1 1791 133 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	
                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                        
2 3279  33 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	
                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                  
3 6072  25 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.

4 2649  20 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	
                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                     
5 1421  18 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	
                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                   
6 6636  40 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	
                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                               
7 5487  28 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	
                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                             
8  850  21 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	
                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                        
9 5763  15 SOME COMMENTS ON MASOCHISM AND THE DELUSION OF OMNIPOTENCE FROM A DEVELOPMENTAL PERSPECTIVE. THIS PAPER EXPLORES THE RELATION OF THE DELUSION OF OMNIPOTENCE TO MASOCHISM AND SUGGESTS THAT THIS FANTASY CONSTITUTES A MAJOR COMPONENT OF THE RESISTANCE SO PROMINENT IN WORK WITH MASOCHISTIC PATIENTS. THE CONNECTIONS AMONG MASOCHISM, OMNIPOTENCE, NEGATIVE THERAPEUTIC REACTION, AND CLINGING TO PAIN ARE DISCUSSED. THE CLASSICAL VIEW HAS BEEN THAT THE FAILURE OF INFANTILE OMNIPOTENCE FORCES THE CHILD TO TURN TO REALITY. OUR EXPERIENCE WITH MASOCHISTIC PATIENTS SUGGESTS THAT IT IS THE REAL FAILURE TO ACHIEVE COMPETENT INTERACTIONS WITH OTHERS THAT FORCES THE CHILD TO TURN TO OMNIPOTENT SOLUTIONS. THE DISTINCTION IS MADE BETWEEN FANTASIES THAT ENHANCE THE REAL CAPACITIES OF THE SELF AND THOSE AIMED AT DENYING AND TRANSFORMING THE PAIN AND INADEQUACY OF THE MOTHER-CHILD RELATIONSHIP. THE EPIGENETIC TRANSFORMATIONS OF OMNIPOTENT FANTASIES THROUGH ALL LEVELS OF DEVELOPMENT ARE DESCRIBED. THE PATIENT'S NEED TO PROTECT THE OMNIPOTENT FANTASY IS DISCUSSED IN RELATION TO RESISTANCE AT EACH PHASE OF ANALYSIS.	1991	
                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                              
10 6632  30 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	
                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                
11   16  28 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	

12 2640  17 EPIGENOMIC AND TRANSCRIPTIONAL PROFILING IDENTIFIES IMPAIRED GLYOXYLATE DETOXIFICATION IN NAFLD AS A RISK FACTOR FOR HYPEROXALURIA. EPIGENETIC MODIFICATIONS (E.G. DNA METHYLATION) IN NAFLD AND THEIR CONTRIBUTION TO DISEASE PROGRESSION AND EXTRAHEPATIC COMPLICATIONS ARE POORLY EXPLORED. HERE, WE USE AN INTEGRATED EPIGENOME AND TRANSCRIPTOME ANALYSIS OF MOUSE NAFLD HEPATOCYTES AND IDENTIFY ALTERATIONS IN GLYOXYLATE METABOLISM, A PATHWAY RELEVANT IN KIDNEY DAMAGE VIA OXALATE RELEASE-A HARMFUL WASTE PRODUCT AND KIDNEY STONE-PROMOTING FACTOR. DOWNREGULATION AND HYPERMETHYLATION OF ALANINE-GLYOXYLATE AMINOTRANSFERASE (AGXT), WHICH DETOXIFIES GLYOXYLATE, PREVENTING EXCESSIVE OXALATE ACCUMULATION, IS ACCOMPANIED BY INCREASED OXALATE FORMATION AFTER METABOLISM OF THE PRECURSOR HYDROXYPROLINE. VIRAL-MEDIATED AGXT TRANSFER OR INHIBITING HYDROXYPROLINE CATABOLISM RESCUES EXCESSIVE OXALATE RELEASE. IN HUMAN STEATOTIC HEPATOCYTES, AGXT IS ALSO DOWNREGULATED AND HYPERMETHYLATED, AND IN NAFLD ADOLESCENTS, STEATOSIS SEVERITY CORRELATES WITH URINARY OXALATE EXCRETION. THUS, THIS WORK IDENTIFIES A REDUCED CAPACITY OF THE STEATOTIC LIVER TO DETOXIFY GLYOXYLATE, TRIGGERING ELEVATED OXALATE, AND PROVIDES A MECHANISTIC EXPLANATION FOR THE INCREASED RISK OF KIDNEY STONES AND CHRONIC KIDNEY DISEASE IN NAFLD PATIENTS.	2021	
                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                               
13 5340  28 QUORUM SENSING AND VIRULENCE OF PSEUDOMONAS AERUGINOSA DURING LUNG INFECTION OF CYSTIC FIBROSIS PATIENTS. PSEUDOMONAS AERUGINOSA IS THE PREDOMINANT MICROORGANISM IN CHRONIC LUNG INFECTION OF CYSTIC FIBROSIS PATIENTS. THE CHRONIC LUNG INFECTION IS PRECEDED BY INTERMITTENT COLONIZATION. WHEN THE CHRONIC INFECTION BECOMES ESTABLISHED, IT IS WELL ACCEPTED THAT THE ISOLATED STRAINS DIFFER PHENOTYPICALLY FROM THE INTERMITTENT STRAINS. DOMINATING CHANGES ARE THE SWITCH TO MUCOIDITY (ALGINATE OVERPRODUCTION) AND LOSS OF EPIGENETIC REGULATION OF VIRULENCE SUCH AS THE QUORUM SENSING (QS). TO ELUCIDATE THE DYNAMICS OF P. AERUGINOSA QS SYSTEMS DURING LONG TERM INFECTION OF THE CF LUNG, WE HAVE INVESTIGATED 238 ISOLATES OBTAINED FROM 152 CF PATIENTS AT DIFFERENT STAGES OF INFECTION RANGING FROM INTERMITTENT TO LATE CHRONIC. ISOLATES WERE CHARACTERIZED WITH REGARD TO QS SIGNAL MOLECULES, ALGINATE, RHAMNOLIPID AND ELASTASE PRODUCTION AND MUTANT FREQUENCY. THE GENETIC BASIS FOR CHANGE IN QS REGULATION WERE INVESTIGATED AND IDENTIFIED BY SEQUENCE ANALYSIS OF LASR, RHLR, LASI AND RHLI. THE FIRST QS SYSTEM TO BE LOST WAS THE ONE ENCODED BY LAS SYSTEM 12 YEARS (MEDIAN VALUE) AFTER THE ONSET OF THE LUNG INFECTION WITH SUBSEQUENT LOSS OF THE RHL ENCODED SYSTEM AFTER 17 YEARS (MEDIAN VALUE) SHOWN AS DEFICIENCIES IN PRODUCTION OF THE 3-OXO-C12-HSL AND C4-HSL QS SIGNAL MOLECULES RESPECTIVELY. THE CONCOMITANT DEVELOPMENT OF QS MALFUNCTION SIGNIFICANTLY CORRELATED WITH THE REDUCED PRODUCTION OF RHAMNOLIPIDS AND ELASTASE AND WITH THE OCCURRENCE OF MUTATIONS IN THE REGULATORY GENES LASR AND RHLR. ACCUMULATION OF MUTATIONS IN BOTH LASR AND RHLR CORRELATED WITH DEVELOPMENT OF HYPERMUTABILITY. INTERESTINGLY, A HIGHER NUMBER OF MUCOID ISOLATES WERE FOUND TO PRODUCE C4-HSL SIGNAL MOLECULES AND RHAMNOLIPIDS COMPARED TO THE NON-MUCOID ISOLATES. AS SEEN FROM THE PRESENT DATA, WE CAN CONCLUDE THAT P. AERUGINOSA AND PARTICULARLY THE MUCOID STRAINS DO NOT LOSE THE QS REGULATION OR THE ABILITY TO PRODUCE RHAMNOLIPIDS UNTIL THE LATE STAGE OF THE CHRONIC INFECTION.	2010	
                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                      
14 6036  30 THE CHARACTERISTICS OF EXTRACHROMOSOMAL CIRCULAR DNA IN PATIENTS WITH END-STAGE RENAL DISEASE. BACKGROUND: END-STAGE RENAL DISEASE (ESRD) IS THE FINAL STAGE OF CHRONIC KIDNEY DISEASE (CKD). IN ADDITION TO THE STRUCTURALLY INTACT CHROMOSOME GENOMIC DNA, THERE IS A DOUBLE-STRANDED CIRCULAR DNA CALLED EXTRACHROMOSOMAL CIRCULAR DNA (ECCDNA), WHICH IS THOUGHT TO BE INVOLVED IN THE EPIGENETIC REGULATION OF HUMAN DISEASE. HOWEVER, THE FEATURES OF ECCDNA IN ESRD PATIENTS ARE BARELY KNOWN. IN THIS STUDY, WE IDENTIFIED ECCDNA FROM ESRD PATIENTS AND HEALTHY PEOPLE, AS WELL AS REVEALED THE CHARACTERISTICS OF ECCDNA IN PATIENTS WITH ESRD. METHODS: USING THE HIGH-THROUGHPUT CIRCLE-SEQUENCING TECHNIQUE, WE EXAMINED THE ECCDNA IN PERIPHERAL BLOOD MONONUCLEAR CELLS (PBMCS) FROM HEALTHY PEOPLE (NC) (N = 12) AND ESRD PATIENTS (N = 16). WE ANALYZED THE LENGTH DISTRIBUTION, GENOME ELEMENTS, AND MOTIFS FEATURE OF ECCDNA IN ESRD PATIENTS. THEN, AFTER IDENTIFYING THE SPECIFIC ECCDNA IN ESRD PATIENTS, WE EXPLORED THE POTENTIAL FUNCTIONS OF THE TARGET GENES OF THE SPECIFIC ECCDNA. FINALLY, WE INVESTIGATED THE PROBABLE HUB ECCDNA USING ALGORITHMS. RESULTS: IN TOTAL, 14,431 AND 11,324 ECCDNAS WERE FOUND IN THE ESRD AND NC GROUPS, RESPECTIVELY, WITH SIZES RANGING FROM 0.01 KB TO 60 KB AT MOST. ADDITIONALLY, THE ESRD GROUP HAD A GREATER DISTRIBUTION OF ECCDNA ON CHROMOSOMES 4, 11, 13, AND 20. IN TWO GROUPS, WE ALSO DISCOVERED SEVERAL MOTIFS OF SPECIFIC ECCDNAS. FURTHERMORE, WE IDENTIFIED 13,715 SPECIFIC ECCDNAS IN THE ESRD GROUP AND 10,585 SPECIFIC ECCDNAS IN THE NC GROUP, BOTH OF WHICH WERE LARGELY ANNOTATED AS MRNA CATALOG. PATHWAY STUDIES USING GENE ONTOLOGY (GO) AND THE KYOTO ENCYCLOPEDIA OF GENES AND GENOMES (KEGG) SHOWED THAT THE SPECIFIC ECCDNA IN ESRD WAS MARKEDLY ENRICHED IN CELL JUNCTION AND COMMUNICATION PATHWAYS. FURTHERMORE, WE IDENTIFIED POTENTIALLY 20 HUB ECCDNA-TARGETING GENES FROM ALL ESRD-SPECIFIC ECCDNA-TARGETING GENES. ALSO, WE FOUND THAT 39 ECCDNA-TARGETING GENES WERE ASSOCIATED WITH ESRD, AND SOME OF THESE ECCDNAS MAY BE RELATED TO THE PATHOGENESIS OF ESRD. CONCLUSIONS: OUR FINDINGS REVEALED THE CHARACTERISTICS OF ECCDNA IN ESRD PATIENTS AND DISCOVERED POTENTIALLY HUB AND ESRD-RELEVANT ECCDNA-TARGETING GENES, SUGGESTING A NOVEL PROBABLE MECHANISM OF ESRD.	2023	
                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                 
15 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. FURTHER RESEARCHES MUST BE PERFORMED EXPLORING THE ROLE OF EPIGENETICS MODIFICATIONS IN CIRCADIAN MANIFESTATIONS OF BRUXISM.	2018	
                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                        
16 1217  31 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.

17 1951  20 EPIGENETIC ACTIVATION OF THE TUSC3 GENE AS A POTENTIAL THERAPY FOR XMEN DISEASE. BACKGROUND: X-LINKED MAGT1 DEFICIENCY WITH INCREASED SUSCEPTIBILITY TO EPSTEIN-BARR VIRUS INFECTION AND N-LINKED GLYCOSYLATION DEFECT (XMEN) DISEASE IS A RARE COMBINED IMMUNODEFICIENCY CAUSED BY LOSS-OF-FUNCTION MUTATIONS IN THE MAGNESIUM TRANSPORTER 1 (MAGT1) GENE. MAGT1 DEFICIENCY IMPAIRS MAGNESIUM TRANSPORT AND THE N-LINKED GLYCOSYLATION OF A PANEL OF PROTEINS, WHICH SUBSEQUENTLY ABOLISHES THE EXPRESSION OF KEY IMMUNE RECEPTORS SUCH AS NATURAL KILLER GROUP 2, MEMBER D (AKA NKG2D). THESE EFFECTS INDUCE IMMUNE SYSTEM ABNORMALITIES, CHRONIC EPSTEIN-BARR VIRUS INFECTION, AND NEOPLASIA. RECENT RESEARCH SHOWS THAT MAGT1 AND TUMOR CANDIDATE SUPPRESSOR 3 (TUSC3) SHARE HIGH SEQUENCE AND FUNCTIONAL SIMILARITY. OBJECTIVE: WE SOUGHT TO INVESTIGATE THE FEASIBILITY OF ACTIVATING TUSC3 EXPRESSION TO PROVIDE A POTENTIAL THERAPEUTIC STRATEGY FOR XMEN DISEASE. METHODS: THE EXPRESSION PROFILES OF MAGT1 AND TUSC3 WERE ANALYZED USING MULTIPLE DATABASES, REAL-TIME QUANTITATIVE PCR, AND WESTERN BLOT. THE EFFECTS OF DECITABINE AND PANOBINOSTAT ON THE REGULATION OF TUSC3 EXPRESSION WERE EXPLORED IN BOTH MAGT1 KNOCKOUT (KO)/PATIENT-DERIVED LYMPHOCYTES AND MAGT1 KO HEPATOCYTES. RESULTS: ALTHOUGH TUSC3 IS WIDELY EXPRESSED, IT IS UNDETECTABLE SPECIFICALLY IN THE IMMUNE SYSTEM AND LIVER, CONSISTENT WITH THE MAIN DISEASED TISSUES IN PATIENTS WITH XMEN DISEASE. CRISPR/CAS9-MEDIATED KO OF MAGT1 IN THE NKL CELL LINE SUCCESSFULLY MIMICKED THE PHENOTYPES OF XMEN PATIENT-DERIVED LYMPHOCYTES, AND EXOGENOUS EXPRESSION OF TUSC3 RESCUED THE DEFICIENCIES IN KO NKL CELLS. USING THIS IN VITRO MODEL, WE IDENTIFIED 2 EPIGENETIC DRUGS, DECITABINE AND PANOBINOSTAT, BY SCREENING. COMBINATION TREATMENT USING THESE 2 DRUGS SIGNIFICANTLY UPREGULATED TUSC3 EXPRESSION AND RESCUED THE IMMUNE AND LIVER ABNORMALITIES. CONCLUSIONS: EPIGENETIC ACTIVATION OF TUSC3 EXPRESSION CONSTITUTES AN EFFECTIVE THERAPEUTIC STRATEGY FOR XMEN DISEASE.	2023	
                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                     
18  760  20 CASZ1: CURRENT IMPLICATIONS IN CARDIOVASCULAR DISEASES AND CANCERS. CASTOR ZINC FINGER 1 (CASZ1) IS A C2H2 ZINC FINGER FAMILY PROTEIN THAT HAS TWO SPLICING VARIANTS, CASZ1A AND CASZ1B. IT IS INVOLVED IN MULTIPLE PHYSIOLOGICAL PROCESSES, SUCH AS TISSUE DIFFERENTIATION AND ALDOSTERONE ANTAGONISM. GENETIC AND EPIGENETIC ALTERNATIONS OF CASZ1 HAVE BEEN CHARACTERIZED IN MULTIPLE CARDIOVASCULAR DISORDERS, SUCH AS CONGENITAL HEART DISEASES, CHRONIC VENOUS DISEASES, AND HYPERTENSION. HOWEVER, LITTLE IS KNOWN ABOUT HOW CASZ1 MECHANICALLY PARTICIPATES IN THE PATHOGENESIS OF THESE DISEASES. OVER THE PAST DECADES, AT FIRST GLANCE, PARADOXICAL INFLUENCES ON CELL BEHAVIORS AND PROGRESSIONS OF DIFFERENT CANCER TYPES HAVE BEEN DISCOVERED FOR CASZ1, WHICH MAY BE EXPLAINED BY A "DOUBLE-AGENT" ROLE FOR CASZ1. IN THIS REVIEW, WE DISCUSS THE PHYSIOLOGICAL FUNCTION OF CASZ1, AND FOCUS ON THE ASSOCIATION OF CASZ1 ABERRATIONS WITH THE PATHOGENESIS OF CARDIOVASCULAR DISEASES AND CANCERS.	2023	
                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                               
19 1843  29 EFFECTS OF TELOMERASE INHIBITOR ON EPIGENETIC CHROMATIN MODIFICATION ENZYMES IN MALIGNANCIES. TELOMERASE HAS A CRITICAL ROLE IN CELL PROLIFERATION, TUMOR MAINTAINING, AND THERAPY RESISTANCE, WHICH ACT BY MODIFYING MANY SIGNALING PATHWAYS. 2-[(E)-3-NAPHTALEN-2-YL-BUT-2-ENOYLAMINO]-BENZOIC ACID (BIBR1532) IS ONE OF THE MOST STUDIED TELOMERASE INHIBITORS, AND IT TARGETS TELOMERASE COMPONENTS TERC AND TERT. IN THIS NOVEL STUDY, WE AIMED TO INVESTIGATE THE EPIGENETIC EFFECTS OF BIBR1532 ON BOTH HEMATOLOGIC MALIGNANCIES AND SOLID TUMORS. K-562 HUMAN CHRONIC MYELOID LEUKEMIA CELL LINE AND U87MG GLIOBLASTOMA CELL LINE WERE COMPARED WITH CONTROL GROUPS WITHOUT BIBR1532 TREATMENT. CYTOTOXIC EFFECTS OF BIBR1532 WERE DETERMINED BY USING WST-1 ASSAY. APOPTOTIC EFFECTS OF BIBR1532 WERE DETECTED BY USING ANNEXIN V METHOD. TO ASSESS EXPRESSION CHANGES IN THE HUMAN EPIGENETIC CHROMATIN MODIFICATION ENZYME GENES, TOTAL RNA WAS ISOLATED FROM K-562 AND U87MG CELLS TREATED WITH BIBR1532 AND UNTREATED CONTROL CELLS. BIBR1532 INDUCED 2.41-FOLD APOPTOTIC CELL DEATH IN U87MG CELL LINES COMPARED WITH CONTROL GROUPS. APOPTOSIS WAS SLIGHTLY INDUCED IN K-562 CELLS WITH BIBR1532 TREATMENT COMPARED WITH CONTROL CELLS. WE OBSERVED THAT BIBR1532 ALSO REGULATES SIMILAR GENES IN BOTH CELL LINES, AND IT IS USEFUL ON EPIGENETIC MECHANISMS. AS A RESULT, TELOMERASE INHIBITOR BIBR1532 HAS A SIGNIFICANT EFFECT ON BOTH HEMATOLOGICAL MALIGNANCIES AND SOLID TUMORS.	2018	
                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                           
20 3239  23 HEPATIC INACTIVATION OF THE TYPE 2 DEIODINASE CONFERS RESISTANCE TO ALCOHOLIC LIVER STEATOSIS. BACKGROUND: A MOUSE WITH HEPATOCYTE-SPECIFIC DEIODINASE TYPE II INACTIVATION (ALB-D2KO) IS RESISTANT TO DIET-INDUCED OBESITY, HEPATIC STEATOSIS, AND HYPERTRIGLYCERIDEMIA DUE TO PERINATAL EPIGENETIC MODIFICATIONS IN THE LIVER. THIS PHENOTYPE IS LINKED TO LOW LEVELS OF ZFP125, A HEPATIC TRANSCRIPTIONAL REPRESSOR THAT PROMOTES LIVER STEATOSIS BY INHIBITING GENES INVOLVED IN PACKAGING AND SECRETION OF VERY-LOW-DENSITY LIPOPROTEIN. METHODS: HERE, WE USED CHRONIC AND BINGE ETHANOL (ETOH) IN MICE TO CAUSE LIVER STEATOSIS. RESULTS: THE ETOH TREATMENT CAUSES A 2.3-FOLD INCREASE IN HEPATIC TRIGLYCERIDE CONTENT; ZFP125 LEVELS WERE APPROXIMATELY 50% HIGHER IN THESE ANIMALS. IN CONTRAST, ALB-D2KO MICE DID NOT DEVELOP ETOH-INDUCED LIVER STEATOSIS. THEY ALSO FAILED TO ELEVATE ZFP125 TO THE SAME LEVELS, DESPITE BEING ON THE ETOH-CONTAINING DIET FOR THE SAME PERIOD OF TIME. THEIR PHENOTYPE WAS ASSOCIATED WITH 1.3- TO 2.9-FOLD UP-REGULATION OF HEPATIC GENES INVOLVED IN LIPID TRANSPORT AND EXPORT THAT ARE NORMALLY REPRESSED BY ZFP125, THAT IS, MTTP, ABCA1, LDLR, APOC1, APOC3, APOE, APOH, AND AZGP1. FURTHERMORE, GENES INVOLVED IN THE ETOH METABOLIC PATHWAY, THAT IS, ALDH2 AND ACSS2, WERE ALSO 1.6- TO 3.1-FOLD UP-REGULATED IN ALB-D2KO ETOH MICE COMPARED WITH CONTROL ANIMALS KEPT ON ETOH. CONCLUSIONS: ETOH CONSUMPTION ELEVATES EXPRESSION OF ZFP125. ALB-D2KO ANIMALS, WHICH HAVE LOWER LEVELS OF ZFP125, ARE MUCH LESS SUSCEPTIBLE TO ETOH-INDUCED LIVER STEATOSIS.	2019
