1  6556 94 TRANSGENERATIONAL EFFECTS OF POLYETHYLENE MICROPLASTIC FRAGMENTS CONTAINING BENZOPHENONE-3 ADDITIVE IN DAPHNIA MAGNA. MATERNAL EXPOSURE TO MICROPLASTICS (MPS) PLAYS AN IMPORTANT ROLE IN THE FITNESS OF UNEXPOSED PROGENY. IN THIS STUDY, THE TRANSGENERATIONAL EFFECTS OF POLYETHYLENE MP FRAGMENTS (17.35 +/- 5.50 MICROM) CONTAINING BENZOPHENONE-3 (BP-3; 2.85 +/- 0.16% W/W) ON CHRONIC TOXICITY (21 D) IN DAPHNIA MAGNA WERE INVESTIGATED ACROSS FOUR GENERATIONS. ONLY D. MAGNA IN THE F0 GENERATION WAS EXPOSED TO MP FRAGMENTS, MP/BP-3 FRAGMENTS, AND BP-3 LEACHATE TO IDENTIFY THE TRANSGENERATIONAL EFFECT IN THE F3 GENERATION. THE MORTALITY OF D. MAGNA INDUCED BY MP AND MP/BP-3 FRAGMENTS WAS RECOVERED IN THE F3 GENERATION, BUT SOMATIC GROWTH AND REPRODUCTION SIGNIFICANTLY DECREASED COMPARED TO THE CONTROL. ADDITIONALLY, REPRODUCTION OF D. MAGNA EXPOSED TO BP-3 LEACHATE SIGNIFICANTLY DECREASED IN THE F3 GENERATION. THESE FINDINGS CONFIRMED THE TRANSGENERATIONAL EFFECTS OF MP FRAGMENT AND BP-3 ADDITIVE ON D. MAGNA. PARTICULARLY, THE ADVERSE EFFECT ON D. MAGNA REPRODUCTION SEEMED TO BE CUMULATIVE ACROSS FOUR GENERATIONS FOR MP/BP-3 FRAGMENTS, WHILE IT WAS AN ACCLIMATION TREND FOR BP-3 LEACHATE. HOWEVER, THERE WAS NO SIGNIFICANT DIFFERENCE IN GLOBAL DNA METHYLATION IN D. MAGNA ACROSS FOUR GENERATIONS, THUS REQUIRING A GENE-SPECIFIC DNA METHYLATION STUDY TO IDENTIFY DIFFERENT EPIGENETIC TRANSGENERATIONAL INHERITANCE.	2022	
                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                   
2  1816 25 EFFECTS OF CHRONIC EXPOSURE TO BENZOPHENONE AND DICLOFENAC ON DNA METHYLATION LEVELS AND REPRODUCTIVE SUCCESS IN A MARINE COPEPOD. THE UV-FILTER BENZOPHENONE AND THE ANTI-INFLAMMATORY DICLOFENAC ARE COMMONLY DETECTED IN THE ENVIRONMENT. THE AIM OF THIS STUDY WAS TO ASSESS THE MULTIGENERATIONAL EFFECTS OF CHRONIC EXPOSURE TO LOW CONCENTRATIONS OF THESE CHEMICALS ON TOXICITY AND DNA METHYLATION LEVELS IN THE COPEPOD GLADIOFERENS PECTINATUS. ACUTE TOXICITY TESTS WERE CONDUCTED TO DETERMINE THE SENSITIVITY OF G. PECTINATUS TO THE CHEMICALS. ALL CHEMICALS IMPACTED BREEDING, HATCHING AND EGG VIABILITY. DICLOFENAC (1 MG.L(-1)) REDUCED THE NUMBER OF EGGS PER GRAVID FEMALE. BENZOPHENONE (0.5 MG.L(-1)) DECREASED EGG HATCHING SUCCESS. EXPOSURE TO THE REFERENCE TOXICANT COPPER (0.02 MG.L(-1)) LED TO UNSUCCESSFUL HATCHING. EFFECTS ON DNA METHYLATION WAS ESTIMATED BY THE PERCENTAGE OF 5- METHYLCYTOSINE. THE TREATMENTS RESULTED IN STRONG DIFFERENCES IN DNA METHYLATION WITH INCREASED METHYLATION IN THE EXPOSED ANIMALS. THE TWO CHEMICALS IMPACTED BOTH EGG VIABILITY AND THE INDUCTION OF DIFFERENTIAL DNA METHYLATION, SUGGESTING POTENTIAL INTRA- AND TRANS-GENERATIONAL EVOLUTIONARY EFFECTS.	2018	
                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                             
3  4527 28 MULTIGENERATIONAL EFFECTS OF 4-METHYLBENZYLIDENE CAMPHOR (4-MBC) ON THE SURVIVAL, DEVELOPMENT AND REPRODUCTION OF THE MARINE COPEPOD TIGRIOPUS JAPONICUS. ONE OF THE MOST WIDELY USED ORGANIC UV FILTERS, 4-METHYLBENZYLIDENE CAMPHOR (4-MBC), IS PRESENT AT HIGH CONCENTRATIONS IN OFFSHORE WATERS. THE MARINE COPEPOD TIGRIOPUS JAPONICUS WAS EXPOSED TO DIFFERENT CONCENTRATIONS OF 4-MBC (I.E., 0, 0.5, 1, 5 AND 10MUGL(-1)) FOR 4 CONSECUTIVE GENERATIONS (F0-F3) TO EVALUATE THE IMPACT OF 4-MBC ON MARINE ECOSYSTEMS. THE RESULTS SHOWED THAT IN THE F0 GENERATION, 4-MBC CAUSED SIGNIFICANT LETHAL TOXICITY IN T. JAPONICAS AT CONCENTRATIONS OF 5 AND 10MUGL(-1) AND THE NAUPLII WERE MORE SENSITIVE TO 4-MBC TOXICITY THAN THE ADULTS. HOWEVER IN THE F1-F3 GENERATIONS, 4-MBC EXPOSURE DID NOT AFFECT THE SURVIVAL RATE. THE HATCHING RATE AND THE DEVELOPMENTAL DURATION FROM THE NAUPLII TO THE COPEPODITE (N-C) AND FROM THE NAUPLII TO ADULT (N-A) DECREASED SIGNIFICANTLY IN THE F1-F2 GENERATIONS AND IN THE F2-F3 GENERATIONS, RESPECTIVELY, EVEN AT THE LOWEST EXPOSURE CONCENTRATION (0.5MUGL(-1)). IN THE SUBSEQUENT TWO GENERATIONS (I.E., THE F4-F5 GENERATIONS) OF RECOVERY EXPOSURE IN CLEAN SEAWATER, THE GROWTH RATES OF THE ORIGINAL 4-MBC EXPOSURE GROUPS WERE STILL FASTER THAN THE CONTROL IN BOTH THE N-C AND N-A STAGES, SUGGESTING POSSIBLE TRANSGENERATIONAL GENETIC AND/OR EPIGENETIC CHANGES UPON CHRONIC 4-MBC EXPOSURE. THE EXPRESSION OF THE ECDYSONE RECEPTOR GENE WAS UP-REGULATED BY 4-MBC, WHICH WAS CONSISTENT WITH THE DECREASE OF THE N-C/N-A DURATION. IN ADDITION, 4-MBC MAY INDUCE OXIDATIVE STRESS AND TRIGGER APOPTOSIS IN T. JAPONICAS, RESULTING IN DEVELOPMENTAL, REPRODUCTIVE AND EVEN LETHAL TOXICITY. A PRELIMINARY RISK ASSESSMENT SUGGESTED THAT UNDER ENVIRONMENTALLY REALISTIC CONCENTRATIONS, 4-MBC HAD SIGNIFICANT POTENTIAL TO POSE A THREAT TO MARINE CRUSTACEANS AND MARINE ECOSYSTEMS.	2018	
                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                       
4   890 27 CHRONIC DIETARY EXPOSURE OF ROOSTERS TO A GLYPHOSATE-BASED HERBICIDE INCREASES SEMINAL PLASMA GLYPHOSATE AND AMPA CONCENTRATIONS, ALTERS SPERM PARAMETERS, AND INDUCES METABOLIC DISORDERS IN THE PROGENY. THE EFFECTS OF CHRONIC DIETARY ROUNDUP (RU) EXPOSURE ON ROOSTER SPERM PARAMETERS, FERTILITY, AND OFFSPRING ARE UNKNOWN. WE INVESTIGATED THE EFFECTS OF CHRONIC RU DIETARY EXPOSURE (46.8 MG KG(-1) DAY(-1) GLYPHOSATE) FOR 5 WEEKS IN 32-WEEK-OLD ROOSTERS (N = 5 RU-EXPOSED AND N = 5 CONTROL (CT)). ALTHOUGH THE CONCENTRATIONS OF GLYPHOSATE AND ITS MAIN METABOLITE AMPA (AMINOMETHYLPHOSPHONIC ACID) INCREASED IN BLOOD PLASMA AND SEMINAL FLUID DURING EXPOSURE, NO SIGNIFICANT DIFFERENCES IN TESTIS WEIGHT AND SPERM CONCENTRATIONS WERE OBSERVED BETWEEN RU AND CT ROOSTERS. HOWEVER, SPERM MOTILITY WAS SIGNIFICANTLY REDUCED, ASSOCIATED WITH DECREASED CALCIUM AND ATP CONCENTRATIONS IN RU SPERMATOZOA. PLASMA TESTOSTERONE AND OESTRADIOL CONCENTRATIONS INCREASED IN RU ROOSTERS. THESE NEGATIVE EFFECTS CEASED 14 DAYS AFTER RU REMOVAL FROM THE DIET. EPIGENETIC ANALYSIS SHOWED A GLOBAL DNA HYPOMETHYLATION IN RU ROOSTERS. AFTER ARTIFICIAL INSEMINATION OF HENS (N = 40) WITH SPERM FROM CT OR RU ROOSTERS, EGGS WERE COLLECTED AND ARTIFICIALLY INCUBATED. EMBRYO VIABILITY DID NOT DIFFER, BUT CHICKS FROM RU ROOSTERS (N = 118) HAD A HIGHER FOOD CONSUMPTION, BODY WEIGHT AND SUBCUTANEOUS ADIPOSE TISSUE CONTENT. CHRONIC DIETARY RU EXPOSURE IN ROOSTERS REDUCES SPERM MOTILITY AND INCREASES PLASMA TESTOSTERONE LEVELS, GROWTH PERFORMANCE, AND FATTENING IN OFFSPRING.	2021	
                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                  
5  3570 25 IMPACT OF JUVENILE HORMONE ANALOGUE INSECTICIDES ON THE WATER FLEA MOINA MACROCOPA: GROWTH, REPRODUCTION AND TRANSGENERATIONAL EFFECT. THE INCREASING QUANTITIES OF INSECTICIDES THAT LEACH INTO WATER BODIES SEVERELY AFFECT THE HEALTH OF THE AQUATIC ENVIRONMENT. JUVENILE HORMONE ANALOGUE (JHA) INSECTICIDES ARE ENDOCRINE DISRUPTERS THAT INTERFERE WITH HORMONAL ACTIVITY IN INSECTS BY MIMICKING JUVENILE HORMONES (JHS). BECAUSE THE STRUCTURE AND FUNCTIONS OF METHYL FARNESOATE IN CRUSTACEANS ARE SIMILAR TO THE INSECT JHS, EXOGENOUS JHA INSECTICIDES MAY CAUSE ADVERSE EFFECTS ON THE GROWTH AND REPRODUCTION IN CRUSTACEANS SIMILAR TO THOSE OBSERVED IN INSECTS. THIS STUDY EXAMINED THE TOXIC EFFECTS OF TWO JHA INSECTICIDES, METHOPRENE AND FENOXYCARB, ON THE WATER FLEA MOINA MACROCOPA. THE 24-H AND 48-H LC(50) VALUES FOR FENOXYCARB AND METHOPRENE WERE 0.53 AND 0.32 MG/L AND 0.70 AND 0.54 MG/L, RESPECTIVELY. CHRONIC EXPOSURE TO THE TWO JHAS CAUSED A SERIES OF TOXIC EFFECTS IN M. MACROCOPA, INCLUDING SHORTENING OF LIFE EXPECTANCY, REPRESSION OF BODY GROWTH, REDUCTION IN FECUNDITY, AND DISTURBED THE EXPRESSION OF GENES INVOLVED IN THE JH SIGNALING PATHWAY, IN CUTICLE DEVELOPMENT, AND IN THE CARBOHYDRATE, AMINO ACID, AND ATP METABOLIC PROCESSES. MOREOVER, JHA EXPOSURE IMPAIRED THE GROWTH AND REPRODUCTION OF THE OFFSPRING OF M. MACROCOPA EXPOSED TO JHAS, EVEN WHEN THE NEONATES WERE NOT EXPOSED TO THE CHEMICALS. IN ADDITION, CHANGES IN THE EXPRESSION OF GENES RELATED TO HISTONE METHYLATION INDICATE THAT EPIGENETIC CHANGES MAY PROMOTE TRANSGENERATIONAL IMPAIRMENT IN M. MACROCOPA. THESE RESULTS DEMONSTRATE THE TOXIC EFFECTS OF FENOXYCARB AND METHOPRENE ON NON-TARGET AQUATIC ORGANISMS. THE DAMAGES DONE BY THESE JHA INSECTICIDES TO THE AQUATIC ENVIRONMENT IS WORTHY OF OUR ATTENTION AND FURTHER STUDIES.	2020	
                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                
6  3303 19 HIGH-FREQUENCY P16(INK) (4A) PROMOTER METHYLATION IS ASSOCIATED WITH HISTONE METHYLTRANSFERASE SETDB1 EXPRESSION IN SPORADIC CUTANEOUS MELANOMA. EPIGENETIC MECHANISMS PARTICIPATE IN MELANOMA DEVELOPMENT AND PROGRESSION. THE EFFECT OF HISTONE MODIFICATIONS AND THEIR CATALYSING ENZYMES OVER EUCHROMATIC PROMOTER DNA METHYLATION IN MELANOMA REMAINS UNCLEAR. THIS STUDY INVESTIGATED THE POTENTIAL ASSOCIATION OF P16(INK) (4A) PROMOTER METHYLATION WITH HISTONE METHYLTRANSFERASE SETDB1 EXPRESSION IN GREEK PATIENTS WITH SPORADIC MELANOMA AND THEIR CORRELATION WITH CLINICOPATHOLOGICAL CHARACTERISTICS. PROMOTER METHYLATION WAS DETECTED BY METHYLATION-SPECIFIC PCR IN 100 PERIPHERAL BLOOD SAMPLES AND 58 MELANOMA TISSUES FROM THE SAME PATIENTS. CELL PROLIFERATION (KI-67 INDEX), P16(INK) (4A) AND SETDB1 EXPRESSION WERE EVALUATED BY IMMUNOHISTOCHEMISTRY. HIGH-FREQUENCY PROMOTER METHYLATION (25.86%) WAS OBSERVED IN TISSUE SAMPLES AND CORRELATED WITH INCREASED CELL PROLIFERATION (P = 0.0514). P16(INK) (4A) PROMOTER METHYLATION WAS HIGHER IN VERTICAL GROWTH-PHASE (60%) MELANOMAS THAN IN RADIAL (40%, P = 0.063) AND THOSE DISPLAYING EPIDERMAL INVOLVEMENT (P = 0.046). IMPORTANTLY, P16(INK) (4A) METHYLATION CORRELATED WITH INCREASED MELANOMA THICKNESS ACCORDING TO BRESLOW INDEX (P = 0.0495) AND MARGINALLY WITH INCREASED CLARK LEVEL (I/II VS III/IV/V, P = 0.070). LOW (1-30%) P16(INK) (4A) EXPRESSION WAS DETECTED AT THE MAJORITY (19 OF 54) OF MELANOMA CASES (35.19%), BEING MARGINALLY CORRELATED WITH TUMOR LYMPHOCYTIC INFILTRATION (P = 0.078). SETDB1 NUCLEAR IMMUNOREACTIVITY WAS OBSERVED IN 47 OF 57 (82.46%) CASES, WHEREAS 27 OF 57 (47.37%) SHOWED CYTOPLASMIC IMMUNOEXPRESSION. CYTOPLASMIC SETDB1 EXPRESSION CORRELATED WITH HIGHER FREQUENCY OF P16(INK) (4A) METHYLATION AND P16(INK) (4A) EXPRESSION (P = 0.033, P = 0.011, RESPECTIVELY). INCREASED NUCLEAR SETDB1 LEVELS WERE ASSOCIATED WITH HIGHER MITOTIC COUNT (0-5/MM(2) VS >5/MM(2) , P = 0.0869), ADVANCED CLARK LEVEL (III-V, P = 0.0380), EPIDERMAL INVOLVEMENT (P = 0.0331) AND THE NON-CHRONIC SUN EXPOSURE-ASSOCIATED MELANOMA TYPE (P = 0.0664). OUR DATA DEMONSTRATE FOR THE FIRST TIME THE ASSOCIATION OF HISTONE METHYLTRANSFERASE SETDB1 WITH FREQUENT METHYLATION OF THE EUCHROMATIC P16(INK) (4A) PROMOTER AND SEVERAL PROGNOSTIC PARAMETERS IN MELANOMAS.	2014	
                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                               
7  1791 26 EFFECT OF CHRONIC RADIATION ON THE FLAX (LINUM USITATISSIMUM L.) GENOME GROWN FOR SIX CONSECUTIVE GENERATIONS IN THE RADIOACTIVE CHERNOBYL AREA. THE GROWTH OF PLANTS UNDER CHRONIC RADIATION STRESS IN THE CHERNOBYL AREA MAY CAUSE CHANGES IN THE GENOME OF PLANTS. TO ASSESS THE EXTENT OF GENETIC AND EPIGENETIC CHANGES IN NUCLEAR DNA, SEEDS OF THE ANNUAL CROP FLAX (LINUM USITATISSIMUM L.) OF THE KYIVSKYI VARIETY, SOWN 21 YEARS AFTER THE ACCIDENT AND GROWN FOR SIX GENERATIONS IN RADIOACTIVE (RAD) AND REMEDIATED (REM) FIELDS WERE ANALYSED. FLAXSEED USED FOR SOWING FIRST GENERATION, WHICH SERVED AS A REFERENCE (REF), WAS ALSO ANALYSED. THE AFLP (AMPLIFIED FRAGMENT LENGTH POLYMORPHISM) REVEALED A HIGHER NUMBER OF SPECIFIC ECORI-MSEI LOCI (3.4-FOLD) IN POOLED FLAXSEED SAMPLES HARVESTED FROM THE RAD FIELD COMPARED WITH THE REM FIELD, INDICATING A LINK BETWEEN THE MUTATION PROCESS IN THE FLAX GENOME AND THE ONGOING ADAPTATION PROCESS. MSAP (METHYLATION-SENSITIVE AMPLIFIED POLYMORPHISM) DETECTING ECORI-MSPI AND ECORI-HPAII LOCI IN FLAX NUCLEAR DNA GENOME SHOWED NO SIGNIFICANT DIFFERENCES IN METHYLATION LEVEL, REACHING ABOUT 33% IN EACH OF THE GROUPS STUDIED. ON THE OTHER HAND, SIGNIFICANT CHANGES IN THE DNA METHYLATION PATTERN OF FLAXSEED SAMPLES HARVESTED FROM THE RAD FIELD COMPARED WITH CONTROLS WERE DETECTED. PAIRWISE F(ST) COMPARISON REVEALED WITHIN BOTH, ECORI-MSPI AND TRANSFORMED METHYLATION-SENSITIVE DATA SETS MORE THAN A 3-FOLD INCREASE OF GENETIC DIVERGENCE IN THE RAD FIELD COMPARED WITH BOTH CONTROLS. THESE RESULTS INDICATE THAT THE NUCLEAR GENOME OF FLAX EXPOSED TO CHRONIC RADIATION FOR SIX GENERATIONS HAS MORE MUTATIONS AND USES DNA METHYLATION AS ONE OF THE ADAPTATION MECHANISMS FOR SUSTAINABILITY UNDER ADVERSE CONDITIONS.	2022	
                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                        
8   967 19 CHRONIC NICOTINE EXPOSURE AUGMENTS RENAL OXIDATIVE STRESS AND INJURY THROUGH TRANSCRIPTIONAL ACTIVATION OF P66SHC. BACKGROUND: CHRONIC NICOTINE (CH-NIC) EXPOSURE EXACERBATES ISCHEMIA/REPERFUSION (I/R)-INDUCED OXIDATIVE STRESS AND ACUTE KIDNEY INJURY (AKI), AND MITOCHONDRIAL PRODUCTION OF REACTIVE OXYGEN SPECIES (ROS) IN CULTURED RENAL PROXIMAL TUBULE CELLS (RPTCS). BECAUSE SER36-PHOSPHORYLATED P66SHC MODULATES MITOCHONDRIAL ROS PRODUCTION AND INJURY OF RPTCS, WE HYPOTHESIZED THAT CH-NIC EXACERBATES AKI BY INCREASING STRESS-INDUCED PHOSPHORYLATION OF P66SHC. METHODS: WE FIRST TESTED WHETHER CH-NIC AUGMENTS I/R-AKI-INDUCED EXPRESSION AND PHOSPHORYLATION OF P66SHC IN VIVO. WE THEN EXAMINED WHETHER KNOCKING DOWN P66SHC, OR IMPAIRING ITS SER36 PHOSPHORYLATION OR BINDING TO CYTOCHROME C, ALTERS THE EFFECTS OF CH-NIC ON OXIDATIVE STRESS (H(2)O(2))-INDUCED PRODUCTION OF ROS, MITOCHONDRIAL DEPOLARIZATION AND INJURY IN RPTCS IN VITRO. RESULTS: WE FOUND THAT CH-NIC INCREASED THE EXPRESSION OF P66SHC IN THE CONTROL AND ISCHEMIC KIDNEYS, BUT ONLY INCREASED ITS SER36 PHOSPHORYLATION AFTER RENAL I/R. KNOCKING DOWN P66SHC OR IMPAIRING PHOSPHORYLATION OF ITS SER36 RESIDUE, VIA THE S36A MUTATION (BUT NOT THE PHOSPHOMIMETIC S36D MUTATION), BLUNTED CH-NIC + H2O2-DEPENDENT ROS PRODUCTION, MITOCHONDRIAL DEPOLARIZATION AND INJURY IN RPTCS. ADDITIONALLY, CH-NIC + H2O2-DEPENDENT BINDING OF P66SHC TO MITOCHONDRIAL CYTOCHROME C WAS ATTENUATED BY S36A MUTATION OF P66SHC, AND IMPAIRING CYTOCHROME C BINDING (VIA W134F MUTATION) ABOLISHED ROS PRODUCTION, MITOCHONDRIAL DEPOLARIZATION AND INJURY, WHILE ECTOPIC OVEREXPRESSION OF P66SHC (WHICH MIMICS CH-NIC TREATMENT) AUGMENTED OXIDANT INJURY. WE DETERMINED THAT CH-NIC STIMULATES THE P66SHC PROMOTER THROUGH P53- AND EPIGENETIC MODIFICATION (PROMOTER HYPOMETHYLATION). CONCLUSIONS: CH-NIC WORSENS OXIDATIVE STRESS-DEPENDENT ACUTE RENAL INJURY BY INCREASING EXPRESSION AND CONSEQUENT OXIDATIVE STRESS-DEPENDENT SER36 PHOSPHORYLATION OF P66SHC. THUS, TARGETING THIS PATHWAY MAY HAVE THERAPEUTIC RELEVANCE IN PREVENTING/AMELIORATING TOBACCO-RELATED KIDNEY INJURY.	2013	
                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                        
9  3279 21 HERITABLE ALTERATION IN DNA METHYLATION INDUCED BY NITROGEN-DEFICIENCY STRESS ACCOMPANIES ENHANCED TOLERANCE BY PROGENIES TO THE STRESS IN RICE (ORYZA SATIVA L.). CYTOSINE METHYLATION IS RESPONSIVE TO VARIOUS BIOTIC- AND ABIOTIC-STRESSES, WHICH MAY PRODUCE HERITABLE EPIALLELES. NITROGEN (N)-DEFICIENCY IS AN ABIOTIC STRESS BEING REPEATEDLY EXPERIENCED BY PLANTS. TO ADDRESS POSSIBLE EPIGENETIC CONSEQUENCES OF N-DEFICIENCY-STRESS, WE INVESTIGATED THE STABILITY OF CYTOSINE METHYLATION IN RICE (ORYZA SATIVA L.) SUBSEQUENT TO A CHRONIC (A WHOLE-GENERATION) N-DEFICIENCY AT TWO LEVELS, MODERATE (20MG/L) AND SEVERE (10MG/L), UNDER HYDROPONIC CULTURE. MSAP ANALYSIS REVEALED THAT LOCUS-SPECIFIC METHYLATION ALTERATION OCCURRED IN LEAF-TISSUE OF THE STRESSED PLANTS (S(0)) EXPERIENCING EITHER LEVEL OF N-DEFICIENCY, WHICH WAS VALIDATED BY GEL-BLOTTING. ANALYSIS ON THREE NON-STRESSED SELF-FED PROGENIES (S(1), S(2) AND S(3)) BY GEL-BLOTTING INDICATED THAT CA. 50% OF THE ALTERED METHYLATION PATTERNS IN SOMATIC CELLS (LEAF) OF THE STRESSED S(0) PLANTS WERE RECAPTURED IN S(1), WHICH WERE THEN STABLY INHERITED TO S(2) AND S(3). BISULFITE SEQUENCING OF TWO VARIANT MSAP LOCI WITH HOMOLOGY TO LOW-COPY RETROTRANSPOSONS ON ONE STRESSED PLANT (S(0)) AND ITS NON-STRESSED PROGENIES (S(1) AND S(2)) SHOWED THAT WHEREAS ONE LOCUS EXHIBITED LIMITED AND NON-HERITABLE CHH METHYLATION ALTERATION, THE OTHER LOCUS MANIFESTED DRAMATIC HERITABLE HYPERMETHYLATION AT NEARLY ALL CYTOSINE SITES WITHIN THE ASSAYED REGION. INTRIGUINGLY, WHEN TWO GROUPS OF S(2) PLANTS DESCENDED FROM THE SAME N-DEFICIENCY-STRESSED S(0) PLANT WERE RE-SUBJECTED TO THE STRESS, THE GROUP INHERITING THE MODIFIED METHYLATION PATTERNS SHOWED ENHANCED TOLERANCE TO THE N-DEFICIENCY-STRESS COMPARED WITH THE GROUP BEARING THE ORIGINAL PATTERNS. OUR RESULTS THUS DEMONSTRATE HERITABILITY OF AN ACQUIRED ADAPTIVE TRAIT IN RICE, WHICH WAS ACCOMPANIED BY EPIGENETIC INHERITANCE OF MODIFIED CYTOSINE METHYLATION PATTERNS, IMPLICATING AN EPIGENETIC BASIS UNDERLYING THE INHERITANCE OF AN ACQUIRED TRAIT IN PLANTS.	2011	
                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                  
10  1217 25 CREG PROTECTS FROM MYOCARDIAL ISCHEMIA/REPERFUSION INJURY BY REGULATING MYOCARDIAL AUTOPHAGY AND APOPTOSIS. AIMS: HUMAN CELLULAR REPRESSOR OF E1A-STIMULATED GENES (CREG) IS A SECRETED GLYCOPROTEIN THAT REGULATES TISSUE AND CELL HOMEOSTASIS AND HAS BEEN SHOWN TO ANTAGONIZE HEART FIBROSIS, WHICH INDICATES A POTENTIAL PROTECTIVE EFFECT OF CREG AGAINST CARDIOMYOCYTE CHRONIC DAMAGE. HOWEVER, LITTLE IS KNOWN ABOUT THE ROLE OF CREG IN MYOCARDIAL TISSUE ACUTE INJURY, IN THIS STUDY, WE AIMED TO INVESTIGATE THE ROLE OF CREG IN MYOCARDIAL ISCHEMIA/REPERFUSION (MI/R) INJURY AND CLARIFY THE MECHANISM OF ACTION. METHODS AND RESULTS: WILD-TYPE CREG (CREG(+/+)), HETEROZYGOUS CREG (CREG(+/-)) MICE AND MICE PRETREATED WITH INFUSION OF RECOMBINANT 0.3MG/KG.D CREG PROTEIN (RECREG(+/+)) WERE SUBJECTED TO 30MIN OF LEFT ASCENDING CORONARY ISCHEMIA AND 24H OF REPERFUSION. EVAN'S BLUE-TRIPHENYL- TETRAZOLIUM CHLORIDE (TTC) SOLUTION AND ECHOCARDIOGRAPHY ANALYSIS WERE USED TO EVALUATE THE EFFECTS OF CREG ON MI/R MICE. THE UNDERLYING MECHANISMS WERE FURTHER DETERMINED BY CULTURED MYOCARDIAL CELLS IN VITRO. OUR FINDINGS REVEALED THAT THE LEVEL OF CREG PROTEIN IN MOUSE HEARTS WAS SIGNIFICANTLY DECREASED AFTER MICE WERE SUBJECTED TO MI/R. MOREOVER, CREG(+/-) MICE HAD LARGER INFARCTION SIZE 2H AFTER REPERFUSION AND WORSE CARDIAC FUNCTION 28DAYS AFTER MI/R INJURY COMPARED TO THAT IN CREG(+/+) MICE. HOWEVER, RECREG(+/+) MICE COULD MAINTAIN CREG AT A HIGH LEVEL EVEN AFTER MI/R INJURY, AND MITIGATED INFARCTION SIZE AND IMPROVED CARDIAC FUNCTION SIGNIFICANTLY. IN CREG(+/-) MICE, MYOCARDIAL AUTOPHAGY WAS DYSFUNCTIONAL CHARACTERIZED BY ACCUMULATION OF LC3A AND P62, WHILE APOPTOTIC CELL NUMBER INCREASE WAS DETECTED BY CLEAVED CASPASE-3 BLOTTING AND TUNEL STAINING. CONVERSELY, DECREASED APOPTOSIS AND ACTIVATED AUTOPHAGY WERE DETECTED IN RECREG(+/+) MICE. FURTHERMORE, CHLOROQUINE, A KIND OF AUTOPHAGY BLOCKER, WAS USED TO DEMONSTRATE RECOMBINANT CREG PROTECTED CARDIOMYOCYTES AGAINST APOPTOSIS MEDIATED BY ACTIVATING AUTOPHAGY BOTH IN VIVO AND IN VITRO. FINALLY, WE FOUND CREG WAS INVOLVED INTO LYSOSOMAL PROTEIN TRANSFER AND IMPROVE CELLULAR AUTOPHAGY. CONCLUSION: CREG PROTECTS HEART AGAINST MI/R INJURY-INDUCED CARDIOMYOCYTES APOPTOSIS BY ACTIVATING LYSOSOMAL AUTOPHAGY.

11    56 21 A GENOME-WIDE ASSOCIATION META-ANALYSIS OF CIRCULATING SEX HORMONE-BINDING GLOBULIN REVEALS MULTIPLE LOCI IMPLICATED IN SEX STEROID HORMONE REGULATION. SEX HORMONE-BINDING GLOBULIN (SHBG) IS A GLYCOPROTEIN RESPONSIBLE FOR THE TRANSPORT AND BIOLOGIC AVAILABILITY OF SEX STEROID HORMONES, PRIMARILY TESTOSTERONE AND ESTRADIOL. SHBG HAS BEEN ASSOCIATED WITH CHRONIC DISEASES INCLUDING TYPE 2 DIABETES (T2D) AND WITH HORMONE-SENSITIVE CANCERS SUCH AS BREAST AND PROSTATE CANCER. WE PERFORMED A GENOME-WIDE ASSOCIATION STUDY (GWAS) META-ANALYSIS OF 21,791 INDIVIDUALS FROM 10 EPIDEMIOLOGIC STUDIES AND VALIDATED THESE FINDINGS IN 7,046 INDIVIDUALS IN AN ADDITIONAL SIX STUDIES. WE IDENTIFIED TWELVE GENOMIC REGIONS (SNPS) ASSOCIATED WITH CIRCULATING SHBG CONCENTRATIONS. LOCI NEAR THE IDENTIFIED SNPS INCLUDED SHBG (RS12150660, 17P13.1, P = 1.8 X 10(-106)), PRMT6 (RS17496332, 1P13.3, P = 1.4 X 10(-11)), GCKR (RS780093, 2P23.3, P = 2.2 X 10(-16)), ZBTB10 (RS440837, 8Q21.13, P = 3.4 X 10(-09)), JMJD1C (RS7910927, 10Q21.3, P = 6.1 X 10(-35)), SLCO1B1 (RS4149056, 12P12.1, P = 1.9 X 10(-08)), NR2F2 (RS8023580, 15Q26.2, P = 8.3 X 10(-12)), ZNF652 (RS2411984, 17Q21.32, P = 3.5 X 10(-14)), TDGF3 (RS1573036, XQ22.3, P = 4.1 X 10(-14)), LHCGR (RS10454142, 2P16.3, P = 1.3 X 10(-07)), BAIAP2L1 (RS3779195, 7Q21.3, P = 2.7 X 10(-08)), AND UGT2B15 (RS293428, 4Q13.2, P = 5.5 X 10(-06)). THESE GENES ENCOMPASS MULTIPLE BIOLOGIC PATHWAYS, INCLUDING HEPATIC FUNCTION, LIPID METABOLISM, CARBOHYDRATE METABOLISM AND T2D, ANDROGEN AND ESTROGEN RECEPTOR FUNCTION, EPIGENETIC EFFECTS, AND THE BIOLOGY OF SEX STEROID HORMONE-RESPONSIVE CANCERS INCLUDING BREAST AND PROSTATE CANCER. WE FOUND EVIDENCE OF SEX-DIFFERENTIATED GENETIC INFLUENCES ON SHBG. IN A SEX-SPECIFIC GWAS, THE LOCI 4Q13.2-UGT2B15 WAS SIGNIFICANT IN MEN ONLY (MEN P = 2.5 X 10(-08), WOMEN P = 0.66, HETEROGENEITY P = 0.003). ADDITIONALLY, THREE LOCI SHOWED STRONG SEX-DIFFERENTIATED EFFECTS: 17P13.1-SHBG AND XQ22.3-TDGF3 WERE STRONGER IN MEN, WHEREAS 8Q21.12-ZBTB10 WAS STRONGER IN WOMEN. CONDITIONAL ANALYSES IDENTIFIED ADDITIONAL SIGNALS AT THE SHBG GENE THAT TOGETHER ALMOST DOUBLE THE PROPORTION OF VARIANCE EXPLAINED AT THE LOCUS. USING AN INDEPENDENT STUDY OF 1,129 INDIVIDUALS, ALL SNPS IDENTIFIED IN THE OVERALL OR SEX-DIFFERENTIATED OR CONDITIONAL ANALYSES EXPLAINED ~15.6% AND ~8.4% OF THE GENETIC VARIATION OF SHBG CONCENTRATIONS IN MEN AND WOMEN, RESPECTIVELY. THE EVIDENCE FOR SEX-DIFFERENTIATED EFFECTS AND ALLELIC HETEROGENEITY HIGHLIGHT THE IMPORTANCE OF CONSIDERING THESE FEATURES WHEN ESTIMATING COMPLEX TRAIT VARIANCE.	2012	
                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                      
12  4048 16 MAINTENANCE AND PHARMACOLOGIC TARGETING OF ROR1 PROTEIN LEVELS VIA UHRF1 IN T(1;19) PRE-B-ALL. EXPRESSION OF THE TRANSMEMBRANE PSEUDOKINASE ROR1 IS REQUIRED FOR SURVIVAL OF T(1;19)-PRE-B-CELL ACUTE LYMPHOBLASTIC LEUKEMIA (T(1;19) PRE-B-ALL), CHRONIC LYMPHOCYTIC LEUKEMIA, AND MANY SOLID TUMORS. HOWEVER, TARGETING ROR1 WITH SMALL-MOLECULES HAS BEEN CHALLENGING DUE TO THE ABSENCE OF ROR1 KINASE ACTIVITY. TO IDENTIFY GENES THAT REGULATE ROR1 EXPRESSION AND MAY, THEREFORE, SERVE AS SURROGATE DRUG TARGETS, WE EMPLOYED AN SIRNA SCREENING APPROACH AND DETERMINED THAT THE EPIGENETIC REGULATOR AND E3 UBIQUITIN LIGASE, UHRF1, IS REQUIRED FOR T(1;19) PRE-B-ALL CELL VIABILITY IN A ROR1-DEPENDENT MANNER. UPON UHRF1 SILENCING, ROR1 PROTEIN IS REDUCED WITHOUT ALTERING ROR1 MRNA, AND ECTOPICALLY EXPRESSED UHRF1 IS SUFFICIENT TO INCREASE ROR1 LEVELS. ADDITIONALLY, PROTEASOME INHIBITION RESCUES LOSS OF ROR1 PROTEIN AFTER UHRF1 SILENCING, SUGGESTING A ROLE FOR THE PROTEASOME IN THE UHRF1-ROR1 AXIS. FINALLY, WE SHOW THAT ROR1-POSITIVE CELLS ARE TWICE AS SENSITIVE TO THE UHRF1-TARGETING DRUG, NAPHTHAZARIN, AND UNDERGO INCREASED APOPTOSIS COMPARED TO ROR1-NEGATIVE CELLS. NAPHTHAZARIN ELICITS REDUCED EXPRESSION OF UHRF1 AND ROR1, AND COMBINATION OF NAPHTHAZARIN WITH INHIBITORS OF PRE-B CELL RECEPTOR SIGNALING RESULTS IN FURTHER REDUCTION OF CELL SURVIVAL COMPARED WITH EITHER INHIBITOR ALONE. THEREFORE, OUR WORK REVEALS A MECHANISM BY WHICH UHRF1 STABILIZES ROR1, SUGGESTING A POTENTIAL TARGETING STRATEGY TO INHIBIT ROR1 IN T(1;19) PRE-B-ALL AND OTHER MALIGNANCIES.	2018	
                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                   
13  2649 17 EPIGENOMIC, GENOMIC, AND TRANSCRIPTOMIC LANDSCAPE OF SCHWANNOMATOSIS. SCHWANNOMATOSIS (SWNTS) IS A GENETIC CANCER PREDISPOSITION SYNDROME THAT MANIFESTS AS MULTIPLE AND OFTEN PAINFUL NEURONAL TUMORS CALLED SCHWANNOMAS (SWNS). WHILE GERMLINE MUTATIONS IN SMARCB1 OR LZTR1, PLUS SOMATIC MUTATIONS IN NF2 AND LOSS OF HETEROZYGOSITY IN CHROMOSOME 22Q HAVE BEEN IDENTIFIED IN A SUBSET OF PATIENTS, LITTLE IS KNOWN ABOUT THE EPIGENOMIC AND GENOMIC ALTERATIONS THAT DRIVE SWNTS-RELATED SWNS (SWNTS-SWNS) IN A MAJORITY OF THE CASES. WE PERFORMED MULTIPLATFORM GENOMIC ANALYSIS AND ESTABLISHED THE MOLECULAR SIGNATURE OF SWNTS-SWNS. WE SHOW THAT SWNTS-SWNS HARBOR DISTINCT GENOMIC FEATURES RELATIVE TO THE HISTOLOGICALLY IDENTICAL NON-SYNDROMIC SPORADIC SWNS (NS-SWNS). WE DEMONSTRATE THE EXISTENCE OF FOUR DISTINCT DNA METHYLATION SUBGROUPS OF SWNTS-SWNS THAT ARE ASSOCIATED WITH SPECIFIC TRANSCRIPTIONAL PROGRAMS AND TUMOR LOCATION. WE SHOW SEVERAL NOVEL RECURRENT NON-22Q DELETIONS AND STRUCTURAL REARRANGEMENTS. WE DETECTED THE SH3PXD2A-HTRA1 GENE FUSION IN SWNTS-SWNS, WITH PREDOMINANCE IN LZTR1-MUTANT TUMORS. IN ADDITION, WE IDENTIFIED SPECIFIC GENETIC, EPIGENETIC, AND ACTIONABLE TRANSCRIPTIONAL PROGRAMS ASSOCIATED WITH PAINFUL SWNTS-SWNS INCLUDING PIGF, VEGF, MEK, AND MTOR PATHWAYS, WHICH MAY BE HARNESSED FOR MANAGEMENT OF THIS SYNDROME.	2021	
                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                    
14  1496 21 DNA IS HYPOMETHYLATED IN CIRCADIAN MANIFESTATIONS OF BRUXISM. OBJECTIVE: THE AIM OF THIS STUDY WAS TO COMPARE THE GLOBAL DNA METHYLATION LEVELS IN PATIENTS UNDER BRUXISM TREATMENT AND A CONTROL GROUP. METHODS: SUBJECTS UNDERGOING BRUXISM TREATMENT WERE CLASSIFIED IN AWAKE BRUXISM (42 PATIENTS), SLEEP BRUXISM (32 PATIENTS) AND BOTH CONDITIONS (42 PATIENTS). THE CONTROL GROUP INCLUDED 42 INDIVIDUALS. A COLORIMETRIC ASSAY (METHYLFLASH METHYLATED DNA 5-MC QUANTIFICATION KIT, EPIGENETIC GROUP INC., NY, USA) WAS USED TO DETERMINE THE GLOBAL DNA METHYLATION LEVELS. RESULTS: STATISTICALLY SIGNIFICANT DIFFERENCES WERE FOUND IN AMOUNTS OF METHYLATED DNA IN ALL CIRCADIAN MANIFESTATIONS OF BRUXISM COMPARED WITH A CONTROL GROUP (SLEEP BRUXISM = 0.95% +/- 2.02%; AWAKE BRUXISM = 0.87% +/- 2.1%; SLEEP AND AWAKE BRUXISM = 0.17% +/- 0.25%; CONTROL = 1.69% +/- 1.6%; KRUSKAL-WALLIS TEST [P = .0001] FOLLOWED BY DUNN'S TEST [P < .05]). CONCLUSION: PATIENTS UNDERGOING BRUXISM TREATMENT EXHIBITED HYPOMETHYLATED DNA LEVELS WHEN COMPARED TO CONTROL GROUP. OUR RESULTS SUGGEST THAT DNA HYPOMETHYLATION MIGHT BE A NOVEL AETIOLOGIC FACTOR IN BRUXISM AETIOLOGY.

AIMS: DNA METHYLATION HAS ITS DISTRIBUTION INFLUENCED BY DNA DEMETHYLATION PROCESSES WITH THE CATALYTIC CONVERSION OF 5-METHYLCYTOSINE (5MC) INTO 5-HYDROXYMETHYLCYTOSINE (5HMC). MYELODYSPLASTIC SYNDROME (MDS) HAS BEEN ASSOCIATED WITH EPIGENETIC DYSREGULATION OF GENES RELATED TO DNA REPAIR SYSTEM, CHRONIC IMMUNE RESPONSE AND CELL CYCLE. METHODS: WE EVALUATED THE TISSUE DNA METHYLATION/HYDROXYMETHYLATION IN BONE MARROW TREPHINE BIOPSIES OF 73 PATIENTS WITH MDS, TRYING TO CORRELATE WITH THE MRNA EXPRESSION OF 21 GENES (POLH, POLL, REV3L, POLN, POLQ, POLI, POLK, IRF-1, IRF-2, IRF-3, IRF-4, IRF-5, IRF6, IRF-7, IRF-8,IRF-9, MAD2, CDC20, AURKA, AURKB AND TPX2). RESULTS: THE M-SCORE (5MC) WAS SIGNIFICANTLY HIGHER IN PATIENTS WITH CHROMOSOMAL ABNORMALITIES THAN PATIENTS WITH NORMAL KARYOTYPE (95% CI -27.127779 TO -2.368020; P=0.022). WE OBSERVED A HIGHER 5MC/5HMC RATIO IN PATIENTS CLASSIFIED AS HIGH-RISK SUBTYPES COMPARED WITH LOW-RISK SUBTYPES (95% CI -72.922115 TO -1.855662; P=0.040) AS WELL AS PATIENTS WITH HYPERCELLULAR BONE MARROW COMPARED WITH PATIENTS WITH NORMOCELLULAR/HYPOCELLULAR BONE MARROW (95% CI -69.189259 TO -0.511828; P=0.047) AND WITH THE PRESENCE OF DYSERYTHROPOIESIS (95% CI 17.077703 TO 51.331388; P=0.001). DNA POLS WITH TRANSLESION ACTIVITY ARE SIGNIFICANTLY INFLUENCED BY METHYLATION. AS 5MC IMMUNOEXPRESSION INCREASES, THE EXPRESSIONS OF POLH (R=-0.816; R(2) =0.665; P=0.000), POLQ (R=-0.790; R(2)=0.624; P=0.001), PCNA (R=-0.635; R(2)=0.403; P=0.020), POLK (R=-0.633; R(2)=0.400; P=0.036 AND REV1 (R=-0.578; R(2)=0.334; P=0.049) DECREASE. CONCLUSIONS: OUR RESULTS CONFIRM THAT THERE IS AN IMBALANCE IN THE DNA METHYLATION IN MDS, INFLUENCING THE DEVELOPMENT OF CHROMOSOMAL ABNORMALITIES WHICH MAY BE ASSOCIATED WITH THE LOW EXPRESSION OF DNA POLYMERASES WITH TRANSLESION SYNTHESIS POLYMERASES ACTIVITY.	2022	
                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                   
16  5170 20 PREDATION RISK DETERMINES PIGMENTATION PHENOTYPE IN NUTHATCHES BY MELANIN-RELATED GENE EXPRESSION EFFECTS. PIGMENTS DETERMINE THE APPEARANCE OF ORGANISMS. HOWEVER, PIGMENT PRODUCTION CAN BE ASSOCIATED WITH PHYSIOLOGICAL CONSTRAINTS AS IN THE CASE OF PHEOMELANIN, THE SULPHURATED FORM OF MELANIN WHOSE SYNTHESIS IN MELANOCYTES CONSUMES CYSTEINE AND CONSEQUENTLY REDUCES THE AVAILABILITY OF GLUTATHIONE (GSH) TO EXERT ANTIOXIDANT PROTECTION. PHEOMELANOGENESIS MAY THUS INCREASE THE SUSCEPTIBILITY TO SUFFER CHRONIC OXIDATIVE STRESS. I INVESTIGATED THE POSSIBILITY THAT ENVIRONMENTAL LABILITY IN THE EXPRESSION OF GENES REGULATING PHEOMELANOGENESIS PROTECTS FROM OXIDATIVE STRESS, A SITUATION IN WHICH GSH IS MOST REQUIRED. BY BROADCASTING ADULT ALARM CALLS, I MANIPULATED THE PERCEPTION OF PREDATION RISK, A NATURAL SOURCE OF OXIDATIVE STRESS, IN FREE-LIVING EURASIAN NUTHATCH SITTA EUROPAEA NESTLINGS DEVELOPING PHEOMELANIN-PIGMENTED FLANK FEATHERS. THE MANIPULATION AFFECTED THE CONSUMPTION OF GSH THAT RESULTED FROM THE EXPRESSION OF TWO GENES (SLC7A11 AND SLC45A2) INFLUENCING CYSTEINE/GSH AVAILABILITY IN CELLS, AS THESE GENES WERE DOWN-REGULATED IN THE FEATHER MELANOCYTES OF THE NESTLINGS WITH LOWEST INTRACELLULAR ANTIOXIDANT CAPACITY (I.E. LOWEST GSH LEVELS). SYSTEMIC OXIDATIVE DAMAGE INCREASED WITH SLC7A11 EXPRESSION IN FEATHER MELANOCYTES, SUGGESTING THAT THE OBSERVED DOWN-REGULATION WAS PHYSIOLOGICALLY ADVANTAGEOUS. THE NESTLINGS EXPOSED TO AN INCREASED PERCEPTION OF PREDATION RISK DEVELOPED FLANK FEATHERS OF REDUCED COLOUR INTENSITY. THESE RESULTS INDICATE THAT PERCEIVED PREDATION RISK CAN DETERMINE THE PIGMENTATION PHENOTYPE BY (PROBABLY EPIGENETIC) EFFECTS ON GENE EXPRESSION THAT PROTECT FROM PHYSIOLOGICAL CONSTRAINTS IMPOSED BY PHEOMELANIN PRODUCTION.	2018	
                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                 
17  6526 22 TRANSCRIPTIONAL CHANGES IN THE OVARIES OF PERCH FROM CHERNOBYL. FISH HAVE BEEN HIGHLY EXPOSED TO RADIATION IN FRESHWATER SYSTEMS AFTER THE CHERNOBYL NUCLEAR POWER PLANT (NPP) ACCIDENT IN 1986 AND IN FRESHWATER AND MARINE SYSTEMS AFTER THE MORE RECENT FUKUSHIMA NPP ACCIDENT IN 2011. IN THE YEARS AFTER THE ACCIDENT, THE RADIOACTIVITY LEVELS RAPIDLY DECLINED DUE TO RADIOACTIVE DECAY AND ENVIRONMENTAL PROCESSES, BUT CHRONIC LOWER DOSE EXPOSURES PERSISTED. TO GAIN INSIGHTS INTO THE LONG-TERM EFFECTS OF ENVIRONMENTAL LOW DOSE RADIATION ON FISH OVARIES DEVELOPMENT, A HIGH-THROUGHPUT TRANSCRIPTOMIC APPROACH INCLUDING A DE NOVO ASSEMBLY WAS APPLIED TO DIFFERENT GONAD PHENOTYPES OF FEMALE PERCH: DEVELOPED GONADS FROM REFERENCE LAKES, DEVELOPED/IRRADIATED FROM MEDIUM CONTAMINATED LAKE, AND BOTH DEVELOPED/IRRADIATED AND UNDEVELOPED FROM MORE HIGHLY CONTAMINATED LAKES. THIS IS THE MOST COMPREHENSIVE ANALYSIS TO DATE OF THE GENE RESPONSES IN WILDLIFE REPRODUCTIVE SYSTEM TO RADIATION. SOME GENE RESPONSES THAT WERE MODULATED IN IRRADIATED GONADS WERE FOUND TO BE INVOLVED IN BIOLOGICAL PROCESSES INCLUDING CELL DIFFERENTIATION AND PROLIFERATION (GGNB2, MOD5, RERGL), CYTOSKELETON ORGANIZATION (K1C18, MTPN), GONAD DEVELOPMENT (NELL2, TCP4), LIPID METABOLISM (LDAH, AT11B, NLTP), REPRODUCTION (CYB5, CYP17A, OVOS), DNA DAMAGE REPAIR (WDHD1, RAD51, HUS1), AND EPIGENETIC MECHANISMS (DMAP1). IDENTIFICATION OF THESE GENES PROVIDES A BETTER UNDERSTANDING OF THE UNDERLYING MOLECULAR MECHANISMS UNDERPINNING THE DEVELOPMENT OF THE GONAD PHENOTYPES OF WILD PERCH AND HOW FISH MAY RESPOND TO CHRONIC EXPOSURE TO RADIATION IN THEIR NATURAL ENVIRONMENT, THOUGH CAUSAL ATTRIBUTION OF GENE RESPONSES REMAINS UNCLEAR IN THE UNDEVELOPED GONADS.	2020	
                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                             
18    16 21 4CRNA NEAT1 SPONGE ADSORPTION OF MIR-378 MODULATES ACTIVITY OF LIPOPOLYSACCHARIDE-TREATED ARTICULAR CHONDROCYTES AND INFLUENCES THE PATHOLOGICAL DEVELOPMENT OF OSTEOARTHRITIS. CONTEXT: OSTEOARTHRITIS (OA) IS A CHRONIC JOINT DISEASE THAT CAN EVENTUALLY LEAD TO DEGENERATION, FIBROSIS, FRACTURES, AND DEFECTS OF THE ARTICULAR CARTILAGE. LONG NON-CODING RNA (LNCRNA) IS A KEY SUBSTANCE IN MANY PROCESSES, SUCH AS EPIGENETIC REGULATION AND CELL-CYCLE AND CELL-DIFFERENTIATION MODULATION, AND ITS RELATIONSHIP WITH OA HAS BEEN REPEATEDLY VERIFIED. OBJECTIVE: THE STUDY INTENDED TO CLARIFY THE INFLUENCE OF LNCRNA NUCLEAR ENRICHED ABUNDANT TRANSCRIPT 1 (NEAT1), LNCRNA NEAT1, ON LIPOPOLYSACCHARIDE (LPS)-INDUCED OA CHONDROCYTES THROUGH SPONGE ADSORPTION OF MICRORNA-378 (MIR-378) AND TO PROVIDE NOVEL INSIGHTS INTO FUTURE DIAGNOSIS AND TREATMENT OF OA. DESIGN: THE RESEARCH TEAM PERFORMED AN ANIMAL STUDY. SETTING: THE STUDY TOOK PLACE IN THE DEPARTMENT OF REHABILITATION MEDICINE AT LINYI PEOPLE'S HOSPITAL IN LINYI, SHANGDONG, CHINA. ANIMALS: THE STUDY'S ANIMALS WERE 10 SPRAGUE DAWLEY (SD) RATS, 3-5 DAYS OLD AND 10-15 G IN WEIGHT, OF THE SPECIFIC-PATHOGEN-FREE (SPF) GRADE. INTERVENTION: THE RAT CHONDROCYTES FOR THE POSITIVE CONTROL GROUP (THE MODEL GROUP) WERE TREATED WITH 500 NG/ML OF LPS TO INDUCE OA. CHONDROCYTES TREATED WITH THE SAME AMOUNT OF NORMAL SALINE WERE USED AS THE NEGATIVE CONTROL GROUP. THE CHONDROCYTES OF THE LPS-INDUCED RATS WERE INTO SIX GROUPS: (1) A POSITIVE CONTROL GROUP TRANSFECTED WITH NEAT1-INTERFERING RNA, THE SH-NEAT1 GROUP; (2) A NEGATIVE CONTROL GROUP NOT TRANSFECTED WITH NEAT1-INTERFERING RNA, THE NEAT1 EMPTY VECTOR (NC-NEAT1) GROUP; (3) AN INTERVENTION GROUP CO-TRANSFECTED WITH NEAT1 INTERFERING RNA AND THE MIR-378 INHIBITOR SEQUENCE (INH-MIR-378 THE SH-NEAT1+ INH-MIR-378 GROUP; (4) A NEGATIVE CONTROL GROUP TRANSFECTED WITH NEAT1 INTERFERING RNA BUT NOT TRANSFECTED WITH THE MIR-378 INHIBITOR SEQUENCE, THE SH-NEAT1+ MIR-378 NEGATIVE CONTROL (NC-MIR-378) GROUP; (5) A NEGATIVE CONTROL GROUP TRANSFECTED WITH THE MIR-378 INHIBITOR SEQUENCE BUT NOT TRANSFECTED WITH NEAT1 INTERFERING RNA, THE NEAT1 EMPTY VECTOR (NC-NEAT1) + INH-MIR-378 GROUP; (6) A NEGATIVE CONTROL GROUP NOT TRANSFECTED WITH EITHER NEAT1 INTERFERING RNA OR THE MIR-378 INHIBITOR SEQUENCE, THE NC-NEAT1 + NC-MIR-378 GROUP. OUTCOME MEASURES: AN OA-CHONDROCYTE MODEL WAS INDUCED BY LPS AND MEASUREMENTS OF NEAT1 AND MIR-378 EXPRESSION WERE MADE BY REAL-TIME QUANTITATIVE REVERSE TRANSCRIPTION (QRT)- POLYMERASE CHAIN REACTION (PCR). THEN, SMALL NEAT1-INTERFERING RNA (SH-NEAT1), EMPTY VECTOR NEAT1 (NC-NEAT1), INHIBITOR-SEQUENCE-MIR-378 (INH-MIR-378), AND NEGATIVE-CONTROL-MIR-378 (NC-MIR-378) WERE TRANSFECTED INTO CELLS, AND CELL VIABILITY AND APOPTOSIS RATE WERE MEASURED. FINALLY, THE STUDY VERIFIED THE RELATIONSHIP BETWEEN NEAT1 AND MIR-378. RESULTS: COMPARED TO THE CONTROL GROUP, NEAT1 WAS SIGNIFICANTLY ELEVATED IN THE MODEL GROUP, AND ITS MIR-378 WAS SIGNIFICANTLY DECREASED. SILENCING NEAT1 CAN ENHANCE OA-CHONDROCYTE ACTIVITY AND DECREASE APOPTOSIS. WHEN NEAT1 AND MIR-378 WERE INHIBITED TOGETHER, AS SHOWN FORT THE NC-NEAT1 + NC-MIR-378 GROUP, NEAT1 EXPRESSION, AS WELL AS THE MULTIPLICATION AND APOPTOSIS ABILITY OF THE OA-MODEL CELLS, WERE THE SAME AS THOSE OF CELLS TRANSFECTED WITH AN EMPTY VECTOR, THE NC-NEAT1 GROUP. ALSO, THE NEAT1 + NC-MIR-378 GROUP'S CELL ACTIVITY WAS LOWER THAN THAT OF THE SH-NEAT1+NC-MIR-378 GROUP BUT HIGHER THAN THAT OF THE NC-NEAT1 + INH-MIR-378 GROUP. FINALLY, HIGHER FLUORESCENCE ACTIVITY OCCURRED FOR NEAT1-MUTANT TYPE (MUT) TRANSFECTED WITH INH-MIR-378. CONCLUSIONS: NEAT1, WHICH IS HIGHLY EXPRESSED IN OA, MEDIATES LPS-INDUCED OA-CHONDROCYTE ACTIVITY THROUGH SPONGE ADSORPTION OF MIR-378.	2022	

19  3416 24 HTR1A, HTR1B, HTR2A, HTR2C AND HTR6 GENE POLYMORPHISMS AND EXTRAPYRAMIDAL SIDE EFFECTS IN HALOPERIDOL-TREATED PATIENTS WITH SCHIZOPHRENIA. SCHIZOPHRENIA IS A SERIOUS, CHRONIC PSYCHIATRIC DISORDER REQUIRING LIFELONG TREATMENT. EXTRAPYRAMIDAL SIDE EFFECTS (EPS) ARE COMMON ADVERSE REACTIONS TO ANTIPSYCHOTIC MEDICATIONS. IN ADDITION TO THE DOPAMINERGIC SYSTEM, SEROTONERGIC MECHANISMS, INCLUDING SEROTONIN (5-HT) RECEPTORS, MIGHT BE INVOLVED IN EPS DEVELOPMENT. THIS STUDY AIMED TO EXAMINE MOLECULAR ASSOCIATIONS OF HTR1A, HTR1B, HTR2A, HTR2C AND HTR6 GENE POLYMORPHISMS WITH ACUTE EPS IN 229 MALE SCHIZOPHRENIA PATIENTS, FOLLOWING TWO WEEKS OF HALOPERIDOL MONOTHERAPY. THE SIMPSON-ANGUS RATING SCALE FOR EXTRAPYRAMIDAL SIDE EFFECTS (SAS), BARNES AKATHISIA RATING SCALE (BARS) AND EXTRAPYRAMIDAL SYMPTOM RATING SCALE (ESRS) WERE USED TO EVALUATE EPS SEVERITY. GENOTYPING WAS PERFORMED USING REAL-TIME PCR, FOLLOWING EXTRACTION OF BLOOD DNA. SIGNIFICANT ACUTE EPS APPEARED IN 48.03% OF SCHIZOPHRENIA PATIENTS. FOR THE RS13212041 HTR1B GENE POLYMORPHISM, AFFECTING MICRORNA REGULATION OF HTR1B GENE EXPRESSION, A HIGHER FREQUENCY OF TT CARRIERS WAS FOUND AMONG HALOPERIDOL-TREATED PATIENTS WITH AKATHISIA WHEN COMPARED TO THE GROUP WITHOUT AKATHISIA SYMPTOMS. IN COMPARISON TO C-ALLELE CARRIERS, PATIENTS CARRYING THE TT GENOTYPE HAD HIGHER AKATHISIA SEVERITY, AS DETERMINED BY THE SAS, BARS AND ESRS SCALES. THESE MOLECULAR FINDINGS SUGGEST POTENTIAL INVOLVEMENT OF 5-HT(1B) RECEPTORS IN AKATHISIA DEVELOPMENT FOLLOWING HALOPERIDOL TREATMENT, AS WELL AS POSSIBLE EPIGENETIC MECHANISMS OF SEROTONERGIC MODULATION ASSOCIATED WITH ANTIPSYCHOTIC-INDUCED EPS.	2020	
                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                             
20  5487 24 REVERSIBLE ALTERATION IN THE EXPRESSION OF THE GAP JUNCTIONAL PROTEIN CONNEXIN 32 DURING TUMOR PROMOTION IN RAT LIVER AND ITS ROLE DURING CELL PROLIFERATION. ALTHOUGH NUMEROUS BIOCHEMICAL MARKERS CAN IDENTIFY PUTATIVE PRENEOPLASTIC ALTERED HEPATIC FOCI (AHF) IN RAT LIVER, NO CONSISTENT PATTERN OF EXPRESSION DURING HEPATOCARCINOGENESIS HAS EMERGED. USING QUANTITATIVE STEREOLOGIC ANALYSES WE DEMONSTRATED THAT DECREASED EXPRESSION OF THE MAJOR HEPATOCYTE GAP JUNCTION PROTEIN, CONNEXIN 32 (CX32), IN RAT AHF IS A CONSISTENT OBSERVATION IN SEVERAL PROTOCOLS OF MULTISTAGE HEPATOCARCINOGENESIS. THIS CHANGE WAS OBSERVED AFTER INITIATION BY EITHER ETHYLNITROSOUREA (ENU) OR DIETHYLNITROSAMINE (DEN), FOLLOWED BY PROMOTION WITH PHENOBARBITAL (PB), DIOXIN, CHLORENDIC ACID, C.I. SOLVENT YELLOW, OR TAMOXIFEN. AHF GENERATED BY WY-14,643, CIPROFIBRATE, AND A CHOLINE/METHIONINE-DEFICIENT DIETARY REGIMEN ALSO SHOWED DECREASED CX32 EXPRESSION. THE DECREASE OF CX32 IN AHF WAS RAPIDLY REVERSIBLE AFTER WITHDRAWAL OF PB, AND THIS CHANGE PRECEDED A REDUCTION IN PLACENTAL ISOZYME OF GLUTATHIONE-S-TRANSFERASE (GST) EXPRESSION IN THE SAME AHF. WITHIN 20 DAYS OF WITHDRAWAL, FEWER THAN 4% OF GST-POSITIVE AHF WERE CX32 DEFICIENT, WHILE THE VOLUME OF TOTAL AHF DECREASED 30%. CHRONIC PB TREATMENT ALSO RESULTED IN A REVERSIBLE DECREASE IN CX32 SPECIFICALLY IN MID- AND CENTRO-LOBULAR HEPATOCYTES. CONTINUOUS THYMIDINE LABELING DEMONSTRATED THAT CX32 COULD BE UNCOUPLED FROM THE CELL CYCLE, SUGGESTING THAT SOME LIVER PROMOTERS MAY ACT DIRECTLY TO ALTER THE EXPRESSION OF CX32. THESE OBSERVATIONS SUGGEST THAT A DECREASE IN CX32 CONTENT WAS A RELATIVELY COMMON EPIGENETIC CHANGE IN AHF INDUCED DURING HEPATOCARCINOGENESIS BY A NUMBER OF INITIATING AND PROMOTING AGENTS BUT THAT THIS CHANGE WAS NOT SUFFICIENT FOR CARCINOGENESIS. THIS CHANGE, HOWEVER, MAY BE NECESSARY FOR THE MECHANISM(S) OF TUMOR PROMOTION, SINCE CX32-POSITIVE AHF DID NOT PROLIFERATE AS READILY AS CX32-DEFICIENT AHF.	1990
