1  514 125 ASSOCIATION OF SHMT1, MAZ, ERG, AND L3MBTL3 GENE POLYMORPHISMS WITH SUSCEPTIBILITY TO MULTIPLE SCLEROSIS. MULTIPLE SCLEROSIS (MS) IS THE MOST COMMON INFLAMMATORY AND CHRONIC DISEASE OF THE CENTRAL NERVOUS SYSTEM (CNS). A COMPLEX INTERACTION BETWEEN GENETIC, ENVIRONMENTAL, AND EPIGENETIC FACTORS IS INVOLVED IN THE PATHOGENESIS OF MS. WITH THE ADVANCEMENT OF GWAS, VARIOUS VARIANTS ASSOCIATED WITH MS HAVE BEEN IDENTIFIED. THIS STUDY AIMED TO EVALUATE THE ASSOCIATION OF SINGLE-NUCLEOTIDE POLYMORPHISMS (SNPS) RS4925166 AND RS1979277 IN THE SHMT1, MAZ RS34286592, ERG RS2836425, AND L3MBTL3 RS4364506 WITH MS. IN THIS CASE-CONTROL STUDY, THE ASSOCIATION OF FIVE SNPS IN SHMT1, MAZ, ERG, AND L3MBTL3 GENES WITH RELAPSING-REMITTING MS (RR-MS) WAS INVESTIGATED IN 190 PATIENTS AND 200 HEALTHY INDIVIDUALS. FOUR SNPS INCLUDING SHMT1 RS4925166, SHMT1 RS1979277, MAZ RS34286592, AND L3MBTL3 RS4364506 WERE GENOTYPED USING PCR-RFLP AND GENOTYPING OF ERG RS2836425 WAS PERFORMED BY TETRA-PRIMER ARMS PCR. OUR FINDINGS SHOWED A SIGNIFICANT DIFFERENCE IN THE ALLELIC FREQUENCIES FOR THE FOUR SNPS OF SHMT1 RS4925166, SHMT1 RS1979277, MAZ RS34286592, AND ERG RS2836425, WHILE THERE WERE NO DIFFERENCES IN THE ALLELE AND GENOTYPE FREQUENCIES FOR L3MBTL3 RS4364506. THESE SIGNIFICANT ASSOCIATIONS WERE OBSERVED FOR THE FOLLOWING GENOTYPES: TT AND GG GENOTYPES OF SHMT1 RS4925166 (OR 0.47 AND 1.90, RESPECTIVELY) GENOTYPE GG OF SHMT1 RS1979277 (OR 0.63), GENOTYPE GG OF MAZ RS34286592 (OR 0.61), TC AND CC GENOTYPES OF ERG RS2836425 (OR 1.89 AND 0.50, RESPECTIVELY). OUR STUDY HIGHLIGHTED THAT PEOPLE WHO ARE CARRYING GENOTYPES INCLUDING GG (SHMT1 RS4925166) AND TC (ERG RS2836425) HAVE THE HIGHEST SUSCEPTIBILITY CHANCE FOR MS, RESPECTIVELY. HOWEVER, GENOTYPES TT (SHMT1 RS4925166), CC (ERG RS2836425), GG (MAZ RS34286592), AND GG (SHMT1 RS1979277) HAD THE HIGHEST NEGATIVE ASSOCIATION (PROTECTIVE EFFECT) WITH MS, RESPECTIVELY. L3MBTL3 RS4364506 WAS FOUND NEITHER AS A PREDISPOSING NOR A PROTECTIVE VARIANT.	2019	
                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                     
2 3903  39 LEP, LDLR AND APOA4 GENE POLYMORPHISMS AND THEIR RELATIONSHIP WITH THE RISK OF OVERWEIGHT, OBESITY AND CHRONIC DISEASES IN ADULTS OF THE STATE OF SUCRE, VENEZUELA. INTRODUCTION: OVERWEIGHT, OBESITY AND SOME CHRONIC DISEASES HAVE BECOME MORE PREVALENT RECENTLY. IT IS WELL KNOWN THAT THEIR CAUSES MAY BE GENETIC, EPIGENETIC, ENVIRONMENTAL, OR A MIXTURE OF THESE. OBJECTIVE: TO ANALYZE THE RELATIONSHIP BETWEEN NINE SINGLE NUCLEOTIDE POLYMORPHISMS OF GENES LEP (RS2167270), LDLR (RS885765, RS688, RS5925, RS55903358, RS5742911) AND APOA4 (RS5095, RS675, RS5110) WITH OBESITY-RELATED PHENOTYPES AND OTHER COMORBIDITIES. MATERIAL AND METHODS: WE RECRUITED 144 ADULTS (76 MALES AND 68 FEMALES, WITH AVERAGE AGES OF 29.93+/-8.29 AND 32.49+/-11.15 YEARS, RESPECTIVELY) IN THE STATE OF SUCRE, VENEZUELA. CLINICAL AND ANTHROPOMETRIC PARAMETERS WERE OBTAINED. GENOTYPE-RISK ASSOCIATIONS WERE STUDIED. WE THEN COMPARED THE AVERAGES REGISTERED FOR ANTHROPOMETRIC AND BIOCHEMICAL VARIABLES PREVIOUSLY ADJUSTED FOR BIOLOGICAL AND ENVIRONMENTAL FACTORS. RESULTS: ACCORDING TO THE BODY MASS INDEX, 38.9% OF THE INDIVIDUALS IN THE SAMPLE WERE OVERWEIGHT (25</=BMI</=29.9 KG/M2) AND 20.1% WERE OBESE (BMI>/=30 KG/M2). GENOTYPE AND ALLELE FREQUENCIES DID NOT DIFFER STATISTICALLY FOR GROUPS WITH NORMAL AND HIGH BODY MASS INDEX (OVERWEIGHT PLUS OBESITY). THE ASSOCIATION BETWEEN LDLR RS5742911 ANCESTRAL GENOTYPE A/A AND HIGH RISK CONDITION RELATED TO HDL-CHOLESTEROL WAS THE ONLY ONE FOUND TO BE SIGNIFICANT (OR=2.944, 95% CI: 1.446-5.996; P=0.003). THE DIFFERENCE IN ADJUSTED MEAN HDL-CHOLESTEROL FOR LDLR RS5742911 GENOTYPES WAS STATISTICALLY SIGNIFICANT (P=0.005) (A/A: 41.50+/-14.81 MG/DL; A/G: 45.00+/-12.07 MG/DL; G/G: 47.17+/-9.43 MG/DL). CONCLUSIONS: FOR MOST OF THE GENETIC VARIANTS STUDIED, THERE WAS AN ASSOCIATION WITH THE PRESENCE OF OVERWEIGHT AND OBESITY AMONG ANCESTRAL GENOTYPE CARRIERS, ALTHOUGH THIS WAS NOT STATISTICALLY SIGNIFICANT. THE RS5742911 POLYMORPHISM MAY BE USEFUL AS AN INDICATOR OF A RISK OF CHRONIC DISEASES.	2016	
                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                         
3 3574  37 IMPACT OF METHIONINE SYNTHASE REDUCTASE POLYMORPHISMS IN CHRONIC MYELOID LEUKEMIA PATIENTS. INTRODUCTION: METABOLISM METHIONINE AND OF FOLATE PLAY A VITAL FUNCTION IN CELLULAR METHYLATION REACTIONS, DNA SYNTHESIS AND EPIGENETIC PROCESS.HOWEVER, POLYMORPHISMS OF METHIONINE HAVE RECEIVED MUCH ATTENTION IN RECENT MEDICAL GENETICS RESEARCH. OBJECTIVES: TO ASCERTAIN WHETHER THE COMMON POLYMORPHISMS OF THE MTRR (METHIONINE SYNTHASE REDUCTASE) A66G GENE COULD PLAY A ROLE IN AFFECTING SUSCEPTIBILITY TO CHRONIC MYELOID LEUKEMIA (CML) IN SUDANESE INDIVIDUALS. METHODS: IN A CASE-CONTROLLED STUDY, WE EXTRACTED AND ANALYZED DNA FROM 200 CML PATIENTS AND 100 HEALTHY CONTROL SUBJECTS BY THE PCR-RFLP METHOD. RESULTS: WE FOUND NO SIGNIFICANT DIFFERENCE IN AGE ORGENDER BETWEEN THE PATIENT GROUP AND CONTROLS. THE MTRR A66G GENOTYPES WERE DISTRIBUTED BASED ON THE HARDY-WEINBERG EQUILIBRIUM (P > 0.05). THE VARIATION OF MTRR A66G WAS LESS SIGNIFICANTLY FREQUENT IN CASES WITH CML (68.35%) THAN IN CONTROLS (87%) (OR = 0.146, 95% CI = 0.162-0.662, P < 0.002). ADDITIONALLY, AG AND GG GENOTYPES AND G ALLELE WERE REDUCING THE CML RISK (ODDS RATIO [OR] = 0.365; 95% CI [0.179-0.746]; P = 0.006; OR = 0.292; 95% CI [0.145-0.590]; P = 0.001 AND OR = 0.146; 95% CI [0.162-0.662]; P = 0.002 AND OR = 2.0; 95% CI [1.3853-2.817]; RESPECTIVELY, (P = 0.000)). CONCLUSIONS: OUR DATA DEMONSTRATED THAT HETEROZYGOUS AND HOMOZYGOUS MUTANT GENOTYPES OF MTRR POLYMORPHISMS WERE ASSOCIATED WITH DECREASED RISK OF DEVELOPING CML IN THE SUDANESE POPULATION.	2022	
                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                       
4 1496  22 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. FURTHER RESEARCHES MUST BE PERFORMED EXPLORING THE ROLE OF EPIGENETICS MODIFICATIONS IN CIRCADIAN MANIFESTATIONS OF BRUXISM.	2018	
                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                        
5  515  42 ASSOCIATION OF SOCS1 (- 820) (RS33977706) GENE POLYMORPHISM WITH CHRONIC PERIODONTITIS: A CASE-CONTROL STUDY IN BRAZILIANS. IT IS EVIDENT THAT THE ACCUMULATION OF PERIODONTAL PATHOGENS OVER THE TEETH SURFACE TRIGGERS PERIODONTITIS; HOWEVER, ITS AGGRAVATION AND SEVERITY DEPEND ON OTHER ELEMENTS SUCH AS ENVIRONMENTAL FACTORS, SYSTEMIC HEALTH AND THE HOST GENETIC AND/OR EPIGENETIC BACKGROUND. TO ADDRESS THIS ISSUE, WE INVESTIGATED THE ASSOCIATION OF TWO GENETIC POLYMORPHISMS PLACED ON PROMOTER REGION OF SOCS1 GENE WITH CHRONIC PERIODONTAL DISEASE. SOCS1 REGULATES JAK/KINASE SIGNALING PATHWAY AND CHANGES IN ITS MRNA EXPRESSION HAVE BEEN RELATED TO DIFFERENT TYPES OF CANCER AND CHRONIC INFLAMMATION, INCLUDING CHRONIC PERIODONTITIS. THE FREQUENCY OF ALLELES AND GENOTYPES OF TWO POLYMORPHISMS IN SOCS1 GENE PROMOTER (POSITION - 820 (RS33977706) AND POSITION - 1478 (RS33989964)) WERE ANALYZED BY PERFORMING RFLP AND TAQMAN SYSTEM IN A TOTAL OF 257 NON-SMOKING SUBJECTS. WE FOUND A LOW FREQUENCY OF A ALLELE AND A/A GENOTYPE OF SOCS1(- 820) POLYMORPHISM IN THE CHRONIC PERIODONTITIS GROUP, ESPECIALLY WHEN SEVERE PERIODONTITIS SAMPLES WERE SEPARATELY ANALYZED (OR = 0.3933; P = 0.0084 (IC95% 0.2112 < MU < 0.7324)), SUGGESTING THAT A ALLELE PLAYS PROTECTIVE EFFECT AGAINST CHRONIC PERIODONTITIS. WE DID NOT FIND ASSOCIATION BETWEEN SOCS1-1478 POLYMORPHISM AND PERIODONTITIS. IN ADDITION, ANALYSIS OF SOCS1 (- 820/- 1478) HAPLOTYPE REVEALED THAT THE FREQUENCY OF A(- 820)/CA(- 1478) HAPLOTYPE DECREASES IN CHRP (P = 0.0089). IN CONCLUSION, OUR STUDY FOUND THAT SOCS1(- 820) POLYMORPHISM IS ASSOCIATED WITH CHRONIC PERIODONTITIS.	2015	
                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                  
6 3416  42 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

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	
                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                              
8   16  26 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	

9   56  38 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	
                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                      
10 1791  23 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	
                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                      
11 6636  54 UNRAVELING A NEW PLAYER IN MULTIPLE SCLEROSIS PATHOGENESIS: THE RNA-BINDING PROTEIN HUR. BACKGROUND: ELAV-LIKE PROTEINS ARE A SMALL FAMILY OF RNA-BINDING PROTEINS THAT ARE FUNDAMENTAL PLAYERS IN POST-TRANSCRIPTIONAL MECHANISMS AND ARE INVOLVED IN THE PATHOGENESIS OF NEUROLOGIC AND PSYCHIATRIC DISORDERS. HUR, THE UBIQUITOUSLY EXPRESSED MEMBER OF THE FAMILY, IS ALSO IMPLICATED IN SUSTAINING INFLAMMATION AND INFLAMMATORY DISEASES, SUPPORTING THE PRODUCTION OF PRO-INFLAMMATORY CYTOKINES. INFLAMMATION PLAYS A CENTRAL ROLE IN MULTIPLE SCLEROSIS (MS), WHICH REPRESENTS THE MOST COMMON CAUSE OF PERMANENT PHYSICAL DISABILITY IN YOUNG ADULTS. MS IS A CHRONIC AUTOIMMUNE DISEASE AFFECTING THE CENTRAL NERVOUS SYSTEM, WITH A COMPLEX AETIOLOGY INVOLVING GENETIC, ENVIRONMENTAL AND EPIGENETIC FACTORS. NO DATA ARE AVAILABLE ON THE POTENTIAL ENTANGLEMENT OF HUR IN MS PATHOGENESIS IN PATIENTS. IN THE PRESENT WORK, WE AIMED AT EXPLORING HUR PROTEIN LEVELS IN PERIPHERAL BLOOD MONONUCLEAR CELLS (PBMCS) FROM MS PATIENTS, COMPARED TO HEALTHY CONTROLS. TO FURTHER ELUCIDATE THE POSSIBLE INVOLVEMENT OF HUR IN MS, WE ALSO INVESTIGATED THE RELATIONSHIP BETWEEN THIS SPECIFIC RNA-BINDING PROTEIN AND HSP70-2 PROTEIN, ALSO CONSIDERING THE HSP70-2 RS1061581 POLYMORPHISM, GIVEN THAT HSP70-2 MRNA HAS BEEN REPORTED AS A HUR TARGET AND THIS SPECIFIC POLYMORPHISM TO BE ASSOCIATED WITH MS RISK. METHODS: ALLELES AND GENOTYPES FOR HSP70-2 RS1061581 POLYMORPHISM WERE ASSESSED, BY USING A POLYMERASE CHAIN REACTION-RESTRICTION FRAGMENT LENGTH POLYMORPHISM, FOLLOWED BY DIGESTION WITH RESTRICTION ENZYME, IN MS PATIENTS AND HEALTHY CONTROLS. PBMCS FROM A SUBGROUP OF PATIENTS AND CONTROLS WERE USED TO EVALUATE HUR AND HSP70-2 PROTEIN CONTENT BY WESTERN BLOT. RESULTS: PBMCS FROM 52 MS PATIENTS HAD A LOWER HUR AND HIGHER HSP70-2 PROTEIN CONTENT COMPARED TO 43 HEALTHY CONTROLS. AN INCREASE OF 100 UNITS OF HUR SIGNIFICANTLY DECREASED THE RISK OF DEVELOPING MS BY 9.8% (OR: 0.902, 95% CI: 0.83-0.98), CONTROLLING FOR HSP70-2 PROTEIN EXPRESSION, HSP70-2 RS1061581 GENOTYPE, AGE AND SEX. MOREOVER, HOLDING HUR LEVELS, AN INCREASE OF 100 UNITS OF HSP70-2 PROTEIN SIGNIFICANTLY INCREASED THE MS RISK BY 18.1% (OR: 1.181, 95% CI: 1.03-1.36) AND THE GENETIC SUSCEPTIBILITY OF DEVELOPING MS FOR HSP70-2 RS1061581 GG CARRIERS IS CONFIRMED. OF INTEREST, MS PATIENTS WITH A MODERATE TO SEVERE FORM OF MS (MSSS >/= 3) SHOWED A TREND TOWARDS A REDUCTION OF HUR PROTEIN LEVELS COMPARED TO PATIENTS WITH MILD DISEASE SEVERITY (MSSS < 3). CONCLUSIONS: HUR PROTEIN LEVELS ARE REDUCED IN MS PATIENTS COMPARED TO HEALTHY SUBJECTS, AND THE PROTEIN AMOUNT MAY CONTINUE TO DECLINE WITH DISEASE PROGRESSION, SUGGESTING A PUTATIVE ROLE OF THIS RNA-BINDING PROTEIN. MOREOVER, OUR RESULTS SUGGEST THAT MS PATHOLOGY MAY HAVE DISRUPTED THE LINK BETWEEN HUR AND ITS TARGET TRANSCRIPT HSP70-2. IT WILL BE IMPORTANT TO FURTHER EXPLORE THE EXACT ROLE OF HUR IN MS, CONSIDERING THE COMPLEX INTERPLAY WITH OTHER RNA-BINDING FACTORS AND TARGET MRNAS.	2020	
                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                             
12 2649  28 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	
                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                   
13 3788  38 INTERLEUKIN 1 ALPHA (IL1A) POLYMORPHISMS AND RISK OF ENDOMETRIOSIS IN IRANIAN POPULATION: A CASE-CONTROL STUDY. ENDOMETRIOSIS IS ONE OF THE MOST COMMON GYNECOLOGICAL DISEASES AND A MAJOR CAUSE OF PAIN AND INFERTILITY. IT IS INFLUENCED BY GENETIC, EPIGENETIC, AND ENVIRONMENTAL FACTORS. RECENTLY, GENOME-WIDE ASSOCIATION STUDIES HAVE REVEALED A STRONG ASSOCIATION BETWEEN IL1A SINGLE NUCLEOTIDE POLYMORPHISMS (SNPS) AND INCREASED RISK OF ENDOMETRIOSIS IN JAPANESE WOMEN. THE AIM OF THE PRESENT STUDY WAS TO EVALUATE THE ASSOCIATION OF THREE IL1A SNPS, RS17561, RS1304037, AND RS2856836 WITH THE RISK OF ENDOMETRIOSIS IN IRANIAN POPULATION. TOTALLY, 105 WOMEN WITH DIAGNOSIS OF ENDOMETRIOSIS AND 102 HEALTHY WOMEN AS CONTROL GROUP WERE INCLUDED. THREE SNPS OF THE IL1A, RS17561 G/T, RS1304037 A/G, AND RS2856836 T/C, WERE GENOTYPED BY PCR AND RFLP. THE RS2856836 TC GENOTYPE WAS SIGNIFICANTLY HIGHER (P = .002; OR = 3.1, 95% CI: 1.5-6.5) IN THE PATIENTS (28.1%) THAN THE CONTROL GROUP (12.7%). THE RS2856836 CC GENOTYPE WAS SIGNIFICANTLY HIGHER (P = .047; OR = 2.3, 95% CI: 1.0-5.3) IN THE PATIENTS (17.5%) THAN THE CONTROL GROUP (10.8%). THE RS2856836 C ALLELE WAS SIGNIFICANTLY HIGHER (P = .001; OR = 2.2, 95% CI: 1.4-3.6) IN THE PATIENTS (31.6%) THAN THE CONTROL GROUP (17.2%). THE IL1A RS2856836 T/C SNP WAS ASSOCIATED WITH SUSCEPTIBILITY TO ENDOMETRIOSIS AND THE RS2856836 C ALLELE MAY INCREASE THE RISK OF ENDOMETRIOSIS IN IRANIAN WOMEN.	2020	
                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                              
14  890  26 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	
                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                
15  850  23 CHILDREN WITH CHRONIC IMMUNE THROMBOCYTOPENIA EXHIBIT HIGH EXPRESSION OF HUMAN ENDOGENOUS RETROVIRUSES TRIM28 AND SETDB1. CHRONIC IMMUNE THROMBOCYTOPENIA (CITP) IS AN AUTOIMMUNE DISEASE WHOSE UNDERLYING BIOLOGIC MECHANISMS REMAIN ELUSIVE. HUMAN ENDOGENOUS RETROVIRUSES (HERVS) DERIVE FROM ANCESTRAL INFECTIONS AND CONSTITUTE ABOUT 8% OF OUR GENOME. A WEALTH OF CLINICAL AND EXPERIMENTAL STUDIES HIGHLIGHTS THEIR PIVOTAL PATHOGENETIC ROLE IN AUTOIMMUNE DISEASES. EPIGENETIC MECHANISMS, SUCH AS THOSE MODULATED BY TRIM28 AND SETDB1, ARE INVOLVED IN HERV ACTIVATION AND REGULATION OF IMMUNE RESPONSE. WE ASSESSED, THROUGH A POLYMERASE CHAIN REACTION REAL-TIME TAQMAN AMPLIFICATION ASSAY, THE TRANSCRIPTION LEVELS OF POL GENES OF HERV-H, HERV-K, AND HERV-W; ENV GENES OF SYNCYTIN (SYN)1, SYN2, AND HERV-W; AS WELL AS TRIM28 AND SETDB1 IN WHOLE BLOOD FROM 34 CHILDREN WITH CITP AND AGE-MATCHED HEALTHY CONTROLS (HC). THE TRANSCRIPTIONAL LEVELS OF ALL HERV SEQUENCES, WITH THE EXCEPTION OF HERV-W-ENV, WERE SIGNIFICANTLY ENHANCED IN CHILDREN WITH CITP AS COMPARED TO HC. PATIENTS ON ELTROMBOPAG TREATMENT EXHIBITED LOWER EXPRESSION OF SYN1, SYN2, AND HERV-W-ENV AS COMPARED TO UNTREATED PATIENTS. THE MRNA CONCENTRATIONS OF TRIM28 AND SETDB1 WERE SIGNIFICANTLY HIGHER AND WERE POSITIVELY CORRELATED WITH THOSE OF HERVS IN CITP PATIENTS. THE OVER-EXPRESSIONS OF HERVS AND TRIM28/SETDB1 AND THEIR POSITIVE CORRELATIONS IN PATIENTS WITH CITP ARE SUGGESTIVE CLUES OF THEIR CONTRIBUTION TO THE PATHOGENESIS OF THE DISEASE AND SUPPORT INNOVATIVE INTERVENTIONS TO INHIBIT HERV AND TRIM28/SETDB1 EXPRESSIONS IN PATIENTS UNRESPONSIVE TO STANDARD THERAPIES.	2023	
                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                      
16 6632  35 UNDERSTANDING THE ROLE OF THE CHROMOSOME 15Q25.1 IN COPD THROUGH EPIGENETICS AND TRANSCRIPTOMICS. CHRONIC OBSTRUCTIVE PULMONARY DISEASE (COPD) IS A MAJOR HEALTH BURDEN IN ADULTS AND CIGARETTE SMOKING IS CONSIDERED THE MOST IMPORTANT ENVIRONMENTAL RISK FACTOR OF COPD. CHROMOSOME 15Q25.1 LOCUS IS ASSOCIATED WITH BOTH COPD AND SMOKING. OUR STUDY AIMS AT UNDERSTANDING THE MECHANISM UNDERLYING THE ASSOCIATION OF CHROMOSOME 15Q25.1 WITH COPD THROUGH EPIGENETIC AND TRANSCRIPTIONAL VARIATION IN A POPULATION-BASED SETTING. TO ASSESS IF COPD-ASSOCIATED VARIANTS IN 15Q25.1 ARE METHYLATION QUANTITATIVE TRAIT LOCI, EPIGENOME-WIDE ASSOCIATION ANALYSIS OF FOUR GENETIC VARIANTS, PREVIOUSLY ASSOCIATED WITH COPD (P < 5 X 10(-8)) IN THE 15Q25.1 LOCUS (RS12914385:C>T-CHRNA3, RS8034191:T>C-HYKK, RS13180:C>T-IREB2 AND RS8042238:C>T-IREB2), WAS PERFORMED IN THE ROTTERDAM STUDY (N = 1489). ALL FOUR VARIANTS WERE SIGNIFICANTLY ASSOCIATED (P < 1.4 X 10(-6)) WITH BLOOD DNA METHYLATION OF IREB2, CHRNA3 AND PSMA4, OF WHICH TWO, INCLUDING IREB2 AND PSMA4, WERE ALSO DIFFERENTIALLY METHYLATED IN COPD CASES AND CONTROLS (P < 0.04). FURTHER ADDITIVE AND MULTIPLICATIVE EFFECTS OF SMOKING WERE EVALUATED AND NO SIGNIFICANT EFFECT WAS OBSERVED. TO EVALUATE IF THESE FOUR GENETIC VARIANTS ARE EXPRESSION QUANTITATIVE TRAIT LOCI, TRANSCRIPTOME-WIDE ASSOCIATION ANALYSIS WAS PERFORMED IN 1087 LUNG SAMPLES. ALL FOUR VARIANTS WERE ALSO SIGNIFICANTLY ASSOCIATED WITH DIFFERENTIAL EXPRESSION OF THE IREB2 3'UTR IN LUNG TISSUES (P < 5.4 X 10(-95)). WE CONCLUDE THAT REGULATORY MECHANISMS AFFECTING THE EXPRESSION OF IREB2 GENE, SUCH AS DNA METHYLATION, MAY EXPLAIN THE ASSOCIATION BETWEEN GENETIC VARIANTS IN CHROMOSOME 15Q25.1 AND COPD, LARGELY INDEPENDENT OF SMOKING.	2018	
                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                               
17  511  27 ASSOCIATION OF RASSF1A HYPERMETHYLATION WITH RISK OF HBV/HCV-INDUCED HEPATOCELLULAR CARCINOMA: A META-ANALYSIS. BACKGROUND: RESEARCHERS HAVE DISCOVERED A LARGE NUMBER OF DNA METHYLATION PATTERNS IN HUMAN CANCER. THESE CANCER-SPECIFIC METHYLATION PATTERNS CAN PROVIDE INFORMATION FOR THE DIAGNOSIS, TREATMENT, AND PROGNOSIS OF CANCER. METHYLATION STUDIES CAN FIND NEW BIOMARKERS BASED ON EPIGENETIC ANALYSIS AND APPLY THESE BIOMARKERS TO CLINICAL ONCOLOGY. MANY STUDIES ON THE ASSOCIATION BETWEEN RAASF1A METHYLATION STATUS AND SUSCEPTIBILITY TO HEPATITIS B VIRUS (HBV)/HEPATITIS C VIRUS (HCV)-INDUCED HEPATOCELLULAR CARCINOMA (HCC) HAVE REACHED CONTROVERSIAL CONCLUSIONS. HENCE, THE CURRENT REVIEW COMPREHENSIVELY ASSESSED THE CORRELATION BETWEEN RAS ASSOCIATION DOMAIN FAMILY 1A (RASSF1A) METHYLATION AND THE RISK OF THE HCV/HBV-INDUCED HCC. METHODS: THE APPROPRIATED PUBLICATIONS WERE EXTRACTED IN EMBASE, PUBMED, WEB OF SCIENCE, COCHRANE LIBRARY, AND CHINA NATIONAL KNOWLEDGE INFRASTRUCTURE DATABASES USING STATA 5.0 SOFTWARE. THE ODDS RATIOS (ORS) WITH 95 % CONFIDENCE INTERVAL (95 % CI) OF RASSF1A METHYLATION WERE COMPUTED. RESULTS: A TOTAL OF 1015 HBV/HCV-RELATED HCC SAMPLES, 124 NON-HBV/HCV-RELATED HCC (NBNC-HCC) SAMPLES, AND 1225 NONTUMOROUS CONTROLS WERE EXTRACTED AND EXAMINED IN THIS RESEARCH. THE FREQUENCY OF THE METHYLATED RASSF1A IN THE HBV/HCV-RELATED TUMOR CASES DISPLAYED A SIGNIFICANTLY INCREASED OR COMPARED WITH THE OVERALL NONTUMOR SAMPLES (OR = 19.372, 95 % CI = 11.060-33.931, P = 0.000). THE FREQUENCY OF THE METHYLATED RASSF1A IN HBV/HCV-RELATED NEOPLASM CASES DISPLAYED A SIGNIFICANTLY INCREASED OR COMPARED WITH THE NON-HBV/HCV-RELATED NEOPLASM (NBNC-NEOPLASM) SAMPLES (OR = 2.150, 95 % CI = 1.398-3.308, P = 0.000). COMPARED WITH NORMAL, CHRONIC HEPATITIS B OR C, CIRRHOSIS, AND PARACANCEROUS SAMPLES, THE POOLED OR OF THE RASSF1A PROMOTER METHYLATION IN THE HBV/HCV-INDUCED HCC SAMPLES WAS 62.785(95 % CI = 35.224-111.909), 25.07 (95 % CI = 13.85-45.36), 6.89 (95 % CI = 3.33-14.264) AND 9.02 (95 % CI = 0.91-89.80), RESPECTIVELY. THE RATE OF RASSF1A HYPERMETHYLATION WAS ROBUSTLY CORRELATED WITH TUMOR SIZE AND VASCULAR INVASION, AND THE POOLED OR WAS 0.346 (95 % CI = 0.210 - 0.569) AND 0.081 (95 % CI = 0.022 - 0.303), RESPECTIVELY. CONCLUSION: RESULTS SHOWED ROBUST ASSOCIATIONS BETWEEN RASSF1A GENE METHYLATION IN PROMOTER REGION AND ENHANCED HBV/HCV-RELATED HCC SUSCEPTIBILITY, THEREBY REVEALING THAT RASSF1A METHYLATION STATUS MAY SERVE AS AN IMPORTANT INDICATOR FOR HCC ONCOGENESIS.	2020	
                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                    
18 2125  33 EPIGENETIC INACTIVATION OF DLX4 IS ASSOCIATED WITH DISEASE PROGRESSION IN CHRONIC MYELOID LEUKEMIA. ABERRANT DNA METHYLATION OF VARIOUS GENES HAS BEEN IDENTIFIED TO BE ASSOCIATED WITH DISEASE PROGRESSION IN CHRONIC MYELOID LEUKEMIA (CML). OUR STUDY WAS INTENDED TO INVESTIGATE DLX4 METHYLATION PATTERN IN DIFFERENT CLINICAL STAGES OF CML AND FURTHER DETERMINE ITS ROLE IN REGULATING DLX4 EXPRESSION. REAL-TIME QUANTITATIVE METHYLATION-SPECIFIC PCR AND BISULFITE SEQUENCING PCR WERE APPLIED TO DETECT DLX4 METHYLATION. 5-AZA-2'-DEOXYCYTIDINE (5-AZA-DC) WAS USED FOR DEMETHYLATION STUDIES. DLX4 WAS SIGNIFICANTLY HYPERMETHYLATED IN CML PATIENTS (P = 0.002) ESPECIALLY IN BLASTIC PHASE (BC) STAGE (P < 0.001) AS COMPARED WITH CONTROLS. MOREOVER, DLX4 METHYLATION LEVEL IN BC STAGE WAS SIGNIFICANTLY HIGHER THAN IN CHRONIC PHASE (CP) STAGE (P < 0.001). DLX4 METHYLATION DENSITY WAS SIGNIFICANTLY INCREASED DURING THE PROGRESSION OF CML AMONG THE TESTED TWO PATIENTS (P < 0.001). DLX4 HYPERMETHYLATION OCCURRED WITH THE HIGHEST INCIDENCE IN BC STAGE (83%), LOWER INCIDENCE IN ACUTE PHASE (AP) STAGE (43%), AND THE LOWEST INCIDENCE IN CP STAGE (26%) (P = 0.001). MOREOVER, T(9; 22) WITH ADDITIONAL ALTERATION CASES HAD SIGNIFICANTLY HIGHER FREQUENCY OF DLX4 HYPERMETHYLATION COMPARED WITH THE OTHER CYTOGENETICS (P = 0.010). SIGNIFICANTLY NEGATIVE CORRELATION WAS OBSERVED BETWEEN DLX4 METHYLATION AND DLX4-TV2 (THE SHORTER DLX4 ISOFORM) EXPRESSION (R = -0.382, P = 0.001, N = 78) BUT NOT BETWEEN DLX4 METHYLATION AND BP1 (THE LONGER DLX4 ISOFORM) EXPRESSION (R = 0.134, P = 0.244, N = 78) IN CML PATIENTS. BOTH DLX4-TV2 AND BP1 MRNA WERE SIGNIFICANTLY INCREASED AFTER 5-AZA-DC TREATMENT IN K562 CELL LINE (P < 0.001). OUR STUDY INDICATED THAT HYPERMETHYLATION OF DLX4 CORRELATED WITH DISEASE PROGRESSION OF CML. MOREOVER, DLX4 EXPRESSION WAS REGULATED BY ITS METHYLATION IN CML.	2015	
                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                              
19 6072  29 THE DNA METHYLOME OF HUMAN VASCULAR ENDOTHELIUM AND ITS USE IN LIQUID BIOPSIES. BACKGROUND: VASCULAR ENDOTHELIAL CELLS (VECS) ARE AN ESSENTIAL COMPONENT OF EACH TISSUE, CONTRIBUTE TO MULTIPLE PATHOLOGIES, AND ARE TARGETED BY IMPORTANT DRUGS. YET, THERE IS A SHORTAGE OF BIOMARKERS TO ASSESS VEC TURNOVER. METHODS: TO DEVELOP DNA METHYLATION-BASED LIQUID BIOPSIES FOR VECS, WE DETERMINED THE METHYLOME OF VECS ISOLATED FROM FRESHLY DISSOCIATED HUMAN TISSUES. FINDINGS: A COMPARISON WITH A HUMAN CELL-TYPE METHYLOME ATLAS YIELDED THOUSANDS OF LOCI THAT ARE UNIQUELY UNMETHYLATED IN VECS. THESE SITES ARE TYPICALLY GENE ENHANCERS, OFTEN RESIDING ADJACENT TO VEC-SPECIFIC GENES. WE ALSO IDENTIFIED HUNDREDS OF GENOMIC LOCI THAT ARE DIFFERENTIALLY METHYLATED IN ORGANOTYPIC VECS, INDICATING THAT VECS FEEDING SPECIFIC ORGANS ARE DISTINCT CELL TYPES WITH A STABLE EPIGENETIC IDENTITY. WE ESTABLISHED UNIVERSAL AND LUNG-SPECIFIC VEC MARKERS AND EVALUATED THEIR PRESENCE IN CIRCULATING CELL-FREE DNA (CFDNA). NEARLY 2.5% OF CFDNA IN THE PLASMA OF HEALTHY INDIVIDUALS ORIGINATES FROM VECS. SEPSIS, GRAFT VERSUS HOST DISEASE, AND CARDIAC CATHETERIZATION ARE ASSOCIATED WITH ELEVATED LEVELS OF VEC-DERIVED CFDNA, INDICATIVE OF VASCULAR DAMAGE. LUNG-SPECIFIC VEC CFDNA IS SELECTIVELY ELEVATED IN PATIENTS WITH CHRONIC OBSTRUCTIVE PULMONARY DISEASE (COPD) OR LUNG CANCER, REVEALING TISSUE-SPECIFIC VASCULAR TURNOVER. CONCLUSIONS: VEC CFDNA BIOMARKERS INFORM VASCULAR DYNAMICS IN HEALTH AND DISEASE, POTENTIALLY CONTRIBUTING TO EARLY DIAGNOSIS AND MONITORING OF PATHOLOGIES, AND ASSESSMENT OF DRUG ACTIVITY.

20 1421  21 DIFFERENTIAL BRAIN ADRA2A AND ADRA2C GENE EXPRESSION AND EPIGENETIC REGULATION IN SCHIZOPHRENIA. EFFECT OF ANTIPSYCHOTIC DRUG TREATMENT. POSTSYNAPTIC ALPHA(2A)-ADRENOCEPTOR DENSITY IS ENHANCED IN THE DORSOLATERAL PREFRONTAL CORTEX (DLPFC) OF ANTIPSYCHOTIC-TREATED SCHIZOPHRENIA SUBJECTS. THIS ALTERATION MIGHT BE DUE TO TRANSCRIPTIONAL ACTIVATION, AND COULD BE REGULATED BY EPIGENETIC MECHANISMS SUCH AS HISTONE POSTTRANSLATIONAL MODIFICATIONS (PTMS). THE AIM OF THIS STUDY WAS TO EVALUATE ADRA2A AND ADRA2C GENE EXPRESSION (CODIFYING FOR ALPHA(2)-ADRENOCEPTOR SUBTYPES), AND PERMISSIVE AND REPRESSIVE HISTONE PTMS AT GENE PROMOTER REGIONS IN THE DLPFC OF SUBJECTS WITH SCHIZOPHRENIA AND MATCHED CONTROLS (N = 24 PAIRS). WE STUDIED THE EFFECT OF ANTIPSYCHOTIC (AP) TREATMENT IN AP-FREE (N = 12) AND AP-TREATED (N = 12) SUBGROUPS OF SCHIZOPHRENIA SUBJECTS AND IN RATS ACUTELY AND CHRONICALLY TREATED WITH TYPICAL AND ATYPICAL ANTIPSYCHOTICS. ADRA2A MRNA EXPRESSION WAS SELECTIVELY UPREGULATED IN AP-TREATED SCHIZOPHRENIA SUBJECTS (+93%) WHEREAS ADRA2C MRNA EXPRESSION WAS UPREGULATED IN ALL SCHIZOPHRENIA SUBJECTS (+53%) REGARDLESS OF ANTIPSYCHOTIC TREATMENT. ACUTE AND CHRONIC CLOZAPINE TREATMENT IN RATS DID NOT ALTER BRAIN CORTEX ADRA2A MRNA EXPRESSION BUT INCREASED ADRA2C MRNA EXPRESSION. BOTH ADRA2A AND ADRA2C PROMOTER REGIONS SHOWED EPIGENETIC MODIFICATION BY HISTONE METHYLATION AND ACETYLATION IN HUMAN DLPFC. THE UPREGULATION OF ADRA2A EXPRESSION IN AP-TREATED SCHIZOPHRENIA SUBJECTS MIGHT BE RELATED TO OBSERVED BIVALENT CHROMATIN AT ADRA2A PROMOTER REGION IN SCHIZOPHRENIA (DEPICTED BY INCREASED PERMISSIVE H3K4ME3 AND REPRESSIVE H3K27ME3) AND COULD BE TRIGGERED BY THE ENHANCED H4K16AC AT ADRA2A PROMOTER. IN CONCLUSION, EPIGENETIC PREDISPOSITION DIFFERENTIALLY MODULATED ADRA2A AND ADRA2C MRNA EXPRESSION IN DLPFC OF SCHIZOPHRENIA SUBJECTS.	2021
