1 6049 157 THE CONCURRENT DECLINE OF SOIL LEAD AND CHILDREN'S BLOOD LEAD IN NEW ORLEANS. LEAD (PB) IS EXTREMELY TOXIC AND A MAJOR CAUSE OF CHRONIC DISEASES WORLDWIDE. PB IS ASSOCIATED WITH HEALTH DISPARITIES, PARTICULARLY WITHIN LOW-INCOME POPULATIONS. IN BIOLOGICAL SYSTEMS, PB MIMICS CALCIUM AND, AMONG OTHER EFFECTS, INTERRUPTS CELL SIGNALING. FURTHERMORE, PB EXPOSURE RESULTS IN EPIGENETIC CHANGES THAT AFFECT MULTIGENERATIONAL GENE EXPRESSION. EXPOSURE TO PB HAS DECREASED THROUGH PRIMARY PREVENTION, INCLUDING REMOVAL OF PB SOLDER FROM CANNED FOOD, REGULATING LEAD-BASED PAINT, AND ESPECIALLY ELIMINATING PB ADDITIVES IN GASOLINE. WHILE RESEARCHERS OBSERVE A CONTINUOUS DECLINE IN CHILDREN'S BLOOD LEAD (BPB), RESERVOIRS OF EXPOSURE PERSIST IN TOPSOIL, WHICH STORES THE LEGACY DUST FROM LEADED GASOLINE AND OTHER SOURCES. OUR SURVEYS OF METROPOLITAN NEW ORLEANS REVEAL THAT MEDIAN TOPSOIL PB IN COMMUNITIES (N = 274) DECREASED 44% FROM 99 MG/KG TO 54 MG/KG (P VALUE OF 2.09 X 10(-08)), WITH A MEDIAN DEPLETION RATE OF APPROXIMATELY 2.4 MG?KG?Y(-1) OVER 15 Y. FROM 2000 THROUGH 2005 TO 2011 THROUGH 2016, CHILDREN'S BPB DECLINED FROM 3.6 MUG/DL TO 1.2 MUG/DL OR 64% (P VALUE OF 2.02 X 10(-85)), A DECREASE OF APPROXIMATELY 0.2 MUG?DL?Y(-1) DURING A MEDIAN OF 12 Y. HERE, WE EXPLORE THE DECLINE OF CHILDREN'S BPB BY EXAMINING A METABOLISM OF CITIES FRAMEWORK OF INPUTS, TRANSFORMATIONS, STORAGES, AND OUTPUTS. OUR FINDINGS INDICATE THAT DECREASING PB IN TOPSOIL IS AN IMPORTANT FACTOR IN THE CONTINUOUS DECLINE OF CHILDREN'S BPB. SIMILAR REDUCTIONS ARE EXPECTED IN OTHER MAJOR US CITIES. THE MOST CONTAMINATED URBAN COMMUNITIES, USUALLY INHABITED BY VULNERABLE POPULATIONS, REQUIRE FURTHER REDUCTIONS OF TOPSOIL PB TO FULFILL PRIMARY PREVENTION FOR THE NATION'S CHILDREN.	2019	
                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                              
2 5353  25 RE-EVALUATION OF POLIHEXANIDE USE IN WOUND ANTISEPSIS IN ORDER TO CLARIFY AMBIGUITIES OF TWO ANIMAL STUDIES. OBJECTIVE: DUE TO CLASSIFICATION OF THE AGENT POLIHEXANIDE (PHMB) IN CATEGORY 2 'MAY CAUSE CANCER' BY THE COMMITTEE FOR RISK ASSESSMENT OF THE EUROPEAN CHEMICALS AGENCY IN 2011, THE USERS OF WOUND ANTISEPTICS MAY BE HIGHLY CONFUSED. IN 2017, THIS STATEMENT WAS UPDATED, DEFINING PHMB UP TO 0.1% AS A PRESERVATIVE SAFE IN ALL COSMETIC PRODUCTS. IN THE INTEREST OF PATIENT SAFETY, A SCIENTIFIC CLARIFICATION OF THE POTENTIAL CARCINOGENICITY OF PHMB IS NECESSARY. METHODS: A MULTIDISCIPLINARY TEAM (MDT) OF MICROBIOLOGISTS, SURGEONS, DERMATOLOGISTS AND BIOCHEMISTS CONDUCTED A BENEFIT-RISK ASSESSMENT TO CLARIFY THE HAZARD OF ANTISEPTIC USE OF PHMB. RESULTS: IN TWO ANIMAL STUDIES, FROM WHICH THE ASSESSMENT OF A CARCINOGENIC RISK WAS DERIVED, PHMB WAS ADMINISTERED ORALLY OVER TWO YEARS IN EXTREMELY HIGH CONCENTRATIONS FAR ABOVE THE NO(A)EL (NO-OBSERVED-(ADVERSE-) EFFECT LEVEL) IN RATS AND MICE. FEEDING IN THE NO(A)EL RANGE RESULTED IN NO ABNORMAL EFFECTS. IN ONE MALE IN THE HIGHEST DOSE GROUP OF 4000PPM PHMB, AN ADENOCARCINOMA WAS FOUND, WHICH THE AUTHOR ATTRIBUTED TO CHRONIC INFLAMMATION OF THE COLON WITH SYSTEMIC ATYPICAL EXPOSURE. THE INCREASING INCIDENCE OF HEMANGIOSARCOMAS HIGHLY PROBABLY RESULTED FROM INCREASED ENDOTHELIAL PROLIFERATION, TRIGGERED BY THE EXCEEDINGLY HIGH DOSAGE FED, BECAUSE PHMB IS NOT GENOTOXIC AND THERE IS NO EVIDENCE FOR EPIGENETIC EFFECTS. DISCUSSION: IT IS WELL KNOWN THAT PHMB IS NOT ABSORBED WHEN APPLIED TOPICALLY. CONSIDERING THE ABSENCE OF GENOTOXICITY AND EPIGENETIC EFFECTS TOGETHER WITH THE INTERPRETATION OF THE ANIMAL STUDIES, IT IS THE CONSENSUS OF THE MULTIDISCIPLINARY EXPERTS THAT A CARCINOGENIC RISK FROM PHMB-USE FOR WOUND ANTISEPSIS CAN BE RULED OUT. CONCLUSION: ON THIS BASIS AND CONSIDERING THEIR EFFECTIVENESS, TOLERABILITY AND CLINICAL EVIDENCE, THE INDICATIONS FOR PHMB BASED WOUND ANTISEPTICS ARE JUSTIFIED.	2019	
                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                         
3 3883  28 KEY CHARACTERISTICS OF CARCINOGENS AS A BASIS FOR ORGANIZING DATA ON MECHANISMS OF CARCINOGENESIS. BACKGROUND: A RECENT REVIEW BY THE INTERNATIONAL AGENCY FOR RESEARCH ON CANCER (IARC) UPDATED THE ASSESSMENTS OF THE > 100 AGENTS CLASSIFIED AS GROUP 1, CARCINOGENIC TO HUMANS (IARC MONOGRAPHS VOLUME 100, PARTS A-F). THIS EXERCISE WAS COMPLICATED BY THE ABSENCE OF A BROADLY ACCEPTED, SYSTEMATIC METHOD FOR EVALUATING MECHANISTIC DATA TO SUPPORT CONCLUSIONS REGARDING HUMAN HAZARD FROM EXPOSURE TO CARCINOGENS. OBJECTIVES AND METHODS: IARC THEREFORE CONVENED TWO WORKSHOPS IN WHICH AN INTERNATIONAL WORKING GROUP OF EXPERTS IDENTIFIED 10 KEY CHARACTERISTICS, ONE OR MORE OF WHICH ARE COMMONLY EXHIBITED BY ESTABLISHED HUMAN CARCINOGENS. DISCUSSION: THESE CHARACTERISTICS PROVIDE THE BASIS FOR AN OBJECTIVE APPROACH TO IDENTIFYING AND ORGANIZING RESULTS FROM PERTINENT MECHANISTIC STUDIES. THE 10 CHARACTERISTICS ARE THE ABILITIES OF AN AGENT TO 1) ACT AS AN ELECTROPHILE EITHER DIRECTLY OR AFTER METABOLIC ACTIVATION; 2) BE GENOTOXIC; 3) ALTER DNA REPAIR OR CAUSE GENOMIC INSTABILITY; 4) INDUCE EPIGENETIC ALTERATIONS; 5) INDUCE OXIDATIVE STRESS; 6) INDUCE CHRONIC INFLAMMATION; 7) BE IMMUNOSUPPRESSIVE; 8) MODULATE RECEPTOR-MEDIATED EFFECTS; 9) CAUSE IMMORTALIZATION; AND 10) ALTER CELL PROLIFERATION, CELL DEATH, OR NUTRIENT SUPPLY. CONCLUSION: WE DESCRIBE THE USE OF THE 10 KEY CHARACTERISTICS TO CONDUCT A SYSTEMATIC LITERATURE SEARCH FOCUSED ON RELEVANT END POINTS AND CONSTRUCT A GRAPHICAL REPRESENTATION OF THE IDENTIFIED MECHANISTIC INFORMATION. NEXT, WE USE BENZENE AND POLYCHLORINATED BIPHENYLS AS EXAMPLES TO ILLUSTRATE HOW THIS APPROACH MAY WORK IN PRACTICE. THE APPROACH DESCRIBED IS SIMILAR IN MANY RESPECTS TO THOSE CURRENTLY BEING IMPLEMENTED BY THE U.S. EPA'S INTEGRATED RISK INFORMATION SYSTEM PROGRAM AND THE U.S. NATIONAL TOXICOLOGY PROGRAM.

4 6636  36 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	

5  645  24 BIRTH DEFECTS IN GAZA: PREVALENCE, TYPES, FAMILIARITY AND CORRELATION WITH ENVIRONMENTAL FACTORS. THIS IS THE FIRST REPORT OF REGISTRATION AT BIRTH, AND OF INCIDENCE OF MAJOR STRUCTURAL BIRTH DEFECTS (BD) OBTAINED IN GAZA AT AL SHIFA HOSPITAL, WHERE 28% OF TOTAL BIRTHS IN GAZA STRIP OCCUR. DOCTORS REGISTERED 4,027 DELIVERIES, WITH A PROTOCOL COMPREHENSIVE OF CLINICAL, DEMOGRAPHIC, KIN AND ENVIRONMENTAL QUESTIONS. PREVALENCE OF BD IS 14/1,000, WITHOUT ASSOCIATION WITH INTERMARRIAGE OR GENDER OF THE CHILD. PREVALENCE OF LATE MISCARRIAGES AND STILL BIRTHS ARE RESPECTIVELY 23.3/1,000 AND 7.4/1,000, AND OF PREMATURE BIRTHS 19.6/1,000. COUPLES WITH A BD CHILD HAVE ABOUT 10 TIMES HIGHER FREQUENCY OF RECURRENCE OF A BD IN THEIR PROGENY THAN THOSE WITH NORMAL CHILDREN, BUT NONE OF THEIR 694 SIBLINGS AND ONLY 10/1,000 OF THEIR 1,423 PROGENY HAD BD, SIMILAR TO THE FREQUENCY IN GENERAL POPULATION. THESE DATA SUGGEST OCCURRENCE OF NOVEL GENETIC AND EPIGENETIC EVENTS IN DETERMINATION OF BD. CHILDREN WITH BD WERE BORN WITH HIGHER FREQUENCY (P < 0 001) IN FAMILIES WHERE ONE OR BOTH PARENTS WERE UNDER "WHITE PHOSPHORUS" ATTACK, THAT IN THE GENERAL POPULATION. BOMBING OF THE FAMILY HOME AND REMOVAL OF THE RUBBLE WERE ALSO FREQUENTLY REPORTED BY COUPLES WITH BD OCCURRENCE. THESE DATA SUGGESTS A CAUSATIVE/FAVORING ROLE OF ACUTE EXPOSURE OF PARENTS TO THE WEAPONS-ASSOCIATED CONTAMINANTS, AND/OR OF THEIR CHRONIC EXPOSURE FROM THEIR PERSISTENCE IN THE ENVIRONMENT ON THE EMBRYONIC DEVELOPMENT OF THEIR CHILDREN.	2012	
                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                          
6 6632  34 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	
                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                  
7 6835  18 [INFLUENCE OF AGE OF PATIENTS WITH BRONCHOPULMONARY PATHOLOGY ON LOW-MOLECULAR DNA CONCENTRATION IN BLOOD PLASMA.]. THE AIM OF THE WORK WAS TO DETERMINE THE CONCENTRATION OF LOW-MOLECULAR-WEIGHT PLASMA DNA (LMDNA) IN PATIENTS WITH COPD AND CHRONIC NON-OBSTRUCTIVE BRONCHITIS (CNONB) OF TWO AGE GROUPS - 34-59 AND 60-80 YEARS. THE LEVELS OF LMDNA IN HEALTHY DONORS, PATIENTS WITH CNONB, HEALTHY RELATIVES OF PATIENTS WITH COPD DID NOT DIFFER, WHILE THE CONCENTRATION OF LMDNA IN PATIENTS WITH COPD WAS SIGNIFICANTLY LOWER. IN COPD PATIENTS AGED 34-59 YEARS, THE LEVEL OF LMDNA WAS REDUCED BY MORE THAN 7 TIMES, AND IN COPD PATIENTS WHO SURVIVED TO 60-80 YEARS, IT WAS 3 TIMES LOWER COMPARED TO THE VALUE OF THIS BIOCHEMICAL INDICATOR IN HEALTHY DONORS OF THE SAME AGE. THE REDUCTION OF LMDNA REFLECTED A REDUCED SYSTEMIC APOPTOTIC ACTIVITY IN THE BODY OF PATIENTS WITH COPD. A SIGNIFICANT DIFFERENCE IN THE CONCENTRATION OF LMDNA IN PATIENTS WITH COPD AND CNONB IN REMISSION CAN BE USED FOR DIFFERENTIAL DIAGNOSIS OF THE DEVELOPMENT OF THESE PATHOLOGICAL PROCESSES. AN INCREASE IN THE LOW LEVEL OF LMDNA IN COPD PATIENTS DURING AGING MAY INDICATE THE INVOLVEMENT OF EPIGENETIC MECHANISMS IN LIFE EXTENSION.	2022	
                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                             
8 5001  21 PERINATAL RISK FACTORS IN TOURETTE'S AND CHRONIC TIC DISORDERS: A TOTAL POPULATION SIBLING COMPARISON STUDY. ADVERSE PERINATAL EVENTS MAY INCREASE THE RISK OF TOURETTE'S AND CHRONIC TIC DISORDERS (TD/CTD), BUT PREVIOUS STUDIES HAVE BEEN UNABLE TO CONTROL FOR UNMEASURED ENVIRONMENTAL AND GENETIC CONFOUNDING. WE AIMED TO PROSPECTIVELY INVESTIGATE POTENTIAL PERINATAL RISK FACTORS FOR TD/CTD, TAKING UNMEASURED FACTORS SHARED BETWEEN FULL SIBLINGS INTO ACCOUNT. A POPULATION-BASED BIRTH COHORT, CONSISTING OF ALL SINGLETONS BORN IN SWEDEN IN 1973-2003, WAS FOLLOWED UNTIL DECEMBER 2013. A TOTAL OF 3 026 861 INDIVIDUALS WERE IDENTIFIED, 5597 OF WHICH HAD A REGISTERED TD/CTD DIAGNOSIS. WE THEN STUDIED DIFFERENTIALLY EXPOSED FULL SIBLINGS FROM 947 942 FAMILIES; OF THESE, 3563 FAMILIES INCLUDED SIBLINGS THAT WERE DISCORDANT FOR TD/CTD. PERINATAL DATA WERE COLLECTED FROM THE MEDICAL BIRTH REGISTER AND TD/CTD DIAGNOSES WERE COLLECTED FROM THE NATIONAL PATIENT REGISTER, USING A PREVIOUSLY VALIDATED ALGORITHM. IN THE FULLY ADJUSTED MODELS, IMPAIRED FETAL GROWTH, PRETERM BIRTH, BREECH PRESENTATION AND CESAREAN SECTION WERE ASSOCIATED WITH A HIGHER RISK OF TD/CTD, LARGELY INDEPENDENT FROM SHARED FAMILY CONFOUNDERS AND MEASURED COVARIATES. MATERNAL SMOKING DURING PREGNANCY WAS ASSOCIATED WITH RISK OF TD/CTD IN A DOSE-RESPONSE MANNER BUT THE ASSOCIATION WAS NO LONGER STATISTICALLY SIGNIFICANT IN THE SIBLING COMPARISON MODELS OR AFTER THE EXCLUSION OF COMORBID ATTENTION-DEFICIT/HYPERACTIVITY DISORDER. A DOSE-RESPONSE RELATIONSHIP BETWEEN THE NUMBER OF ADVERSE PERINATAL EVENTS AND INCREASED RISK FOR TD/CTD WAS ALSO OBSERVED, WITH HAZARD RATIOS RANGING FROM 1.41 (95% CONFIDENCE INTERVAL (CI): 1.33-1.50) FOR ONE EVENT TO 2.42 (95% CI: 1.65-3.53) FOR FIVE OR MORE EVENTS. THESE RESULTS PAVE THE WAY FOR FUTURE GENE BY ENVIRONMENT INTERACTION AND EPIGENETIC STUDIES IN TD/CTD.	2018	
                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                          
9 6036  28 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	
                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                   
10 3907  24 LEUCOCYTIC DNA METHYLATION OF INTERLEUKIN-6 PROMOTER REDUCTION IN PRE-HYPERTENSIVE YOUNG ADULTS. BACKGROUND: PRE-HYPERTENSION IS ASSOCIATED WITH INCREASED RISK OF CARDIOVASCULAR DISEASE. CHRONIC INFLAMMATION PLAYS AN IMPORTANT ROLE IN THE PATHOPHYSIOLOGY OF ESSENTIAL HYPERTENSION, WITH EPIGENETIC DYSREGULATION INVOLVEMENT. NEVERTHELESS, THE ROLE OF DNA METHYLATION IN PREHYPERTENSIVE STATE IS UNKNOWN. THE AIM OF THIS STUDY WAS TO INVESTIGATE THE ASSOCIATION BETWEEN DNA METHYLATION LEVEL OF INTERLEUKIN-6 (IL-6) PROMOTER IN PRE-HYPERTENSIVE (PREHT) AND NORMOTENSIVE (NT) YOUNG ADULTS. METHODS: A TOTAL OF 80 NT AND 80 PREHT HEALTHY SUBJECTS AGED BETWEEN 18-45 YEARS WERE RECRUITED IN KUANTAN, PAHANG, MALAYSIA USING AN OBSERVATIONAL CROSS-SECTIONAL STUDY APPROACH. DNA METHYLATION LEVEL OF IL-6 PROMOTER IN PERIPHERAL LEUKOCYTES WERE MEASURED USING BISULPHITE CONVERSION AND METHYLIGHT ASSAY. RESULTS: THERE WAS NO SIGNIFICANT DIFFERENCE IN AGE BETWEEN NT AND PREHT (P = 0.655). THE MEAN BLOOD PRESSURE WAS 110(8)/73(5) MMHG IN NT AND 125(7)/82(5) MMHG IN PREHT SUBJECTS. THE IL-6 PROMOTER METHYLATION LEVEL WAS SIGNIFICANTLY LOWER IN PREHT COMPARED TO NT SUBJECTS (P < 0.001). CONCLUSION: THE CURRENT STUDY DEMONSTRATES THAT HYPOMETHYLATION OF IL-6 PROMOTER WAS ASSOCIATED WITH PRE-HYPERTENSION IN YOUNG ADULTS. THUS, IL-6 METHYLATION COULD BE USED AS AN EARLY INDICATOR FOR PREDICTING HYPERTENSION AND RELATED RISK OF CARDIOVASCULAR DISEASES IN PREHYPERTENSIVE SUBJECTS. GENE EXPRESSION AND LONGITUDINAL STUDIES ARE WARRANTED TO EXAMINE THE METHYLATION EFFECT ON IL-6 EXPRESSION OVER TIME.	2019	
                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                       
11 4740  27 NOVEL GENETIC VARIANTS ASSOCIATED WITH CHRONIC KIDNEY DISEASE PROGRESSION. SIGNIFICANCE STATEMENT: EGFR SLOPE HAS BEEN USED AS A SURROGATE OUTCOME FOR PROGRESSION OF CKD. HOWEVER, GENETIC MARKERS ASSOCIATED WITH EGFR SLOPE AMONG PATIENTS WITH CKD WERE UNKNOWN. WE AIMED TO IDENTIFY GENETIC SUSCEPTIBILITY LOCI ASSOCIATED WITH EGFR SLOPE. A TWO-PHASE GENOME-WIDE ASSOCIATION STUDY IDENTIFIED SINGLE NUCLEOTIDE POLYMORPHISMS (SNPS) IN TPPP AND FAT1-LINC02374 , AND 22 OF THEM WERE USED TO DERIVE POLYGENIC RISK SCORES THAT MARK THE DECLINE OF EGFR BY DISRUPTING BINDING OF NEARBY TRANSCRIPTION FACTORS. THIS WORK IS THE FIRST TO IDENTIFY THE IMPACT OF TPPP AND FAT1-LINC02374 ON CKD PROGRESSION, PROVIDING PREDICTIVE MARKERS FOR THE DECLINE OF EGFR IN PATIENTS WITH CKD. BACKGROUND: THE INCIDENCE OF CKD IS ASSOCIATED WITH GENETIC FACTORS. HOWEVER, GENETIC MARKERS ASSOCIATED WITH THE PROGRESSION OF CKD HAVE NOT BEEN FULLY ELUCIDATED. METHODS: WE CONDUCTED A GENOME-WIDE ASSOCIATION STUDY AMONG 1738 PATIENTS WITH CKD, MAINLY FROM THE KOREAN COHORT STUDY FOR OUTCOMES IN PATIENTS WITH CKD. THE OUTCOME WAS EGFR SLOPE. WE PERFORMED A REPLICATION STUDY FOR DISCOVERED SINGLE NUCLEOTIDE POLYMORPHISMS (SNPS) WITH P <10 -6 IN 2498 PATIENTS WITH CKD FROM THE CHRONIC RENAL INSUFFICIENCY COHORT STUDY. SEVERAL EXPRESSION QUANTITATIVE TRAIT LOCI (EQTL) STUDIES, PATHWAY ENRICHMENT ANALYSES, EXPLORATION OF EPIGENETIC ARCHITECTURE, AND PREDICTING DISRUPTION OF TRANSCRIPTION FACTOR (TF) BINDING SITES EXPLORED POTENTIAL BIOLOGICAL IMPLICATIONS OF THE LOCI. WE DEVELOPED AND EVALUATED THE EFFECT OF POLYGENIC RISK SCORES (PRS) ON INCIDENT CKD OUTCOMES. RESULTS: SNPS IN TWO NOVEL LOCI, TPPP AND FAT1-LINC02374 , WERE REPLICATED (RS59402340 IN TPPP , PDISCOVERY =7.11X10 -7 , PCRIC =8.13X10 -4 , PMETA =7.23X10 -8 ; RS28629773 IN FAT1-LINC02374 , PDISCOVERY =6.08X10 -7 , PCRIC =4.33X10 -2 , PMETA =1.87X10 -7 ). THE EQTL STUDIES REVEALED THAT THE REPLICATED SNPS REGULATED THE EXPRESSION LEVEL OF NEARBY GENES ASSOCIATED WITH KIDNEY FUNCTION. FURTHERMORE, THESE SNPS WERE NEAR GENE ENHANCER REGIONS AND PREDICTED TO DISRUPT THE BINDING OF TFS. PRS BASED ON THE INDEPENDENTLY SIGNIFICANT TOP 22 SNPS WERE SIGNIFICANTLY ASSOCIATED WITH CKD OUTCOMES. CONCLUSIONS: THIS STUDY DEMONSTRATES THAT SNP MARKERS IN THE TPPP AND FAT1-LINC02374 LOCI COULD BE PREDICTIVE MARKERS FOR THE DECLINE OF EGFR IN PATIENTS WITH CKD.	2023	
                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                
12 1109  27 COMMERCIAL PROCESSED SOY-BASED FOOD PRODUCT CONTAINS GLYCATED AND GLYCOXIDATED LUNASIN PROTEOFORMS. NUTRACEUTICALS HAVE BEEN PROPOSED TO EXERT POSITIVE EFFECTS ON HUMAN HEALTH AND CONFER PROTECTION AGAINST MANY CHRONIC DISEASES. A MAJOR BIOACTIVE COMPONENT OF SOY-BASED FOODS IS LUNASIN PEPTIDE, WHICH HAS POTENTIAL TO EXERT A MAJOR IMPACT ON THE HEALTH OF HUMAN CONSUMERS WORLDWIDE, BUT THE BIOCHEMICAL FEATURES OF DIETARY LUNASIN STILL REMAIN POORLY CHARACTERIZED. IN THIS STUDY, LUNASIN WAS PURIFIED FROM A SOY-BASED FOOD PRODUCT VIA STRONG ANION EXCHANGE SOLID PHASE EXTRACTION AND THEN SUBJECTED TO TOP-DOWN MASS SPECTROMETRY ANALYSIS THAT REVEALED IN DETAIL THE MOLECULAR DIVERSITY OF LUNASIN IN PROCESSED SOYBEAN FOODS. WE DETECTED MULTIPLE GLYCATED PROTEOFORMS TOGETHER WITH POTENTIALLY TOXIC ADVANCED GLYCATION END PRODUCTS (AGES) DERIVED FROM LUNASIN. IN BOTH CASES, MODIFICATION SITES WERE LYS24 AND LYS29 LOCATED AT THE HELICAL REGION THAT SHOWS STRUCTURAL HOMOLOGY WITH A CONSERVED REGION OF CHROMATIN-BINDING PROTEINS. THE IDENTIFIED POST-TRANSLATIONAL MODIFICATIONS MAY HAVE AN IMPORTANT REPERCUSSION ON LUNASIN EPIGENETIC REGULATORY CAPACITY. TAKING TOGETHER, OUR RESULTS DEMONSTRATE THE IMPORTANCE OF PROPER CHEMICAL CHARACTERIZATION OF COMMERCIAL PROCESSED FOOD PRODUCTS TO ASSESS THEIR IMPACT ON CONSUMER'S HEALTH AND RISK OF CHRONIC DISEASES.	2016	
                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                               
13 4492  24 MONOZYGOTIC TWINS DISCORDANT FOR ROHHAD PHENOTYPE. RAPID-ONSET OBESITY WITH HYPOTHALAMIC DYSFUNCTION, HYPOVENTILATION, AND AUTONOMIC DYSREGULATION (ROHHAD) FALLS WITHIN A GROUP OF PEDIATRIC DISORDERS WITH BOTH RESPIRATORY CONTROL AND AUTONOMIC NERVOUS SYSTEM DYSREGULATION. CHILDREN WITH ROHHAD TYPICALLY PRESENT AFTER 1.5 YEARS OF AGE WITH RAPID WEIGHT GAIN AS THE INITIAL SIGN. SUBSEQUENTLY, THEY DEVELOP ALVEOLAR HYPOVENTILATION, AUTONOMIC NERVOUS SYSTEM DYSREGULATION, AND, IF UNTREATED, CARDIORESPIRATORY ARREST. TO OUR KNOWLEDGE, THIS IS THE FIRST REPORT OF DISCORDANT PRESENTATION OF ROHHAD IN MONOZYGOTIC TWINS. TWIN GIRLS, BORN AT TERM, HAD CONCORDANT GROWTH AND DEVELOPMENT UNTIL 8 YEARS OF AGE. FROM 8 TO 12 YEARS OF AGE, THE AFFECTED TWIN DEVELOPED FEATURES CHARACTERISTIC OF ROHHAD INCLUDING OBESITY, ALVEOLAR HYPOVENTILATION, SCOLIOSIS, HYPOTHALAMIC DYSFUNCTION (CENTRAL DIABETES INSIPIDUS, HYPOTHYROIDISM, PREMATURE PUBARCHE, AND GROWTH HORMONE DEFICIENCY), RIGHT PARASPINAL/THORACIC GANGLIONEUROBLASTOMA, SEIZURES, AND AUTONOMIC DYSREGULATION INCLUDING ALTERED PAIN PERCEPTION, LARGE AND SLUGGISHLY REACTIVE PUPILS, HYPOTHERMIA, AND PROFOUND BRADYCARDIA THAT REQUIRED A CARDIAC PACEMAKER. RESULTS OF GENETIC TESTING FOR PHOX2B (CONGENITAL CENTRAL HYPOVENTILATION SYNDROME DISEASE-DEFINING GENE) MUTATIONS WERE NEGATIVE. WITH EARLY RECOGNITION AND CONSERVATIVE MANAGEMENT, THE AFFECTED TWIN HAD EXCELLENT NEUROCOGNITIVE OUTCOME THAT MATCHED THAT OF THE UNAFFECTED TWIN. THE UNAFFECTED TWIN DEMONSTRATED RAPID WEIGHT GAIN LATER IN AGE BUT NOT DEVELOPMENT OF SIGNS/SYMPTOMS CONSISTENT WITH ROHHAD. THIS DISCORDANT TWIN PAIR DEMONSTRATES KEY FEATURES OF ROHHAD INCLUDING THE IMPORTANCE OF EARLY RECOGNITION (ESPECIALLY HYPOVENTILATION), COMPLEXITY OF SIGNS/SYMPTOMS AND CLINICAL COURSE, AND IMPORTANCE OF INITIATING COMPREHENSIVE, MULTISPECIALTY CARE. THESE CASES CONFOUND THE HYPOTHESIS OF A MONOGENIC ETIOLOGY FOR ROHHAD AND INDICATE ALTERNATIVE ETIOLOGIES INCLUDING AUTOIMMUNE OR EPIGENETIC PHENOMENON OR A COMBINATION OF GENETIC PREDISPOSITION AND ACQUIRED PRECIPITANT.	2011	
                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                            
14 2674  29 ETHOSUXIMIDE REDUCES EPILEPTOGENESIS AND BEHAVIORAL COMORBIDITY IN THE GAERS MODEL OF GENETIC GENERALIZED EPILEPSY. PURPOSE: ETHOSUXIMIDE (ESX) IS A DRUG OF CHOICE FOR THE SYMPTOMATIC TREATMENT OF ABSENCE SEIZURES. CHRONIC TREATMENT WITH ESX HAS BEEN REPORTED TO HAVE DISEASE-MODIFYING ANTIEPILEPTOGENIC ACTIVITY IN THE WAG/RIJ RAT MODEL OF GENETIC GENERALIZED EPILEPSY (GGE) WITH ABSENCE SEIZURES. HERE WE EXAMINED WHETHER CHRONIC TREATMENT WITH ESX (1) POSSESSES ANTIEPILEPTOGENIC EFFECTS IN THE GENETIC ABSENCE EPILEPSY RATS FROM STRASBOURG (GAERS) MODEL OF GGE, (2) IS ASSOCIATED WITH A MITIGATION OF BEHAVIORAL COMORBIDITIES, AND (3) INFLUENCES GENE EXPRESSION IN THE SOMATOSENSORY CORTEX REGION WHERE SEIZURES ARE THOUGHT TO ORIGINATE. METHODS: GAERS AND NONEPILEPTIC CONTROL (NEC) RATS WERE CHRONICALLY TREATED WITH ESX (IN DRINKING WATER) OR CONTROL (TAP WATER) FROM 3 TO 22 WEEKS OF AGE. SUBSEQUENTLY, ALL ANIMALS RECEIVED TAP WATER ONLY FOR ANOTHER 12 WEEKS TO ASSESS ENDURING EFFECTS OF TREATMENT. SEIZURE FREQUENCY AND ANXIETY-LIKE BEHAVIORS WERE SERIALLY ASSESSED THROUGHOUT THE EXPERIMENTAL PARADIGM. TREATMENT EFFECTS ON THE EXPRESSION OF KEY COMPONENTS OF THE EPIGENETIC MOLECULAR MACHINERY, THE DNA METHYLTRANSFERASE ENZYMES, WERE ASSESSED USING QUANTITATIVE POLYMERASE CHAIN REACTION (QPCR). KEY FINDINGS: ESX TREATMENT SIGNIFICANTLY REDUCED SEIZURES IN GAERS DURING THE TREATMENT PHASE, AND THIS EFFECT WAS MAINTAINED DURING THE 12-WEEK POSTTREATMENT PHASE (P < 0.05). FURTHERMORE, THE ANXIETY-LIKE BEHAVIORS PRESENT IN GAERS WERE REDUCED BY ESX TREATMENT (P < 0.05). MOLECULAR ANALYSIS REVEALED THAT ESX TREATMENT WAS ASSOCIATED WITH INCREASED EXPRESSION OF DNA METHYLTRANSFERASE ENZYME MESSENGER RNA (MRNA) IN CORTEX. SIGNIFICANCE: CHRONIC ESX TREATMENT HAS DISEASE-MODIFYING EFFECTS IN THE GAERS MODEL OF GGE, WITH ANTIEPILEPTOGENIC EFFECTS AGAINST ABSENCE SEIZURES AND MITIGATION OF BEHAVIORAL COMORBIDITIES. THE CELLULAR MECHANISM FOR THESE EFFECTS MAY INVOLVE EPIGENETIC MODIFICATIONS.	2013	
                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                       
15 1187  30 COPD GWAS VARIANT AT 19Q13.2 IN RELATION WITH DNA METHYLATION AND GENE EXPRESSION. CHRONIC OBSTRUCTIVE PULMONARY DISEASE (COPD) IS AMONG THE MAJOR HEALTH BURDENS IN ADULTS. WHILE CIGARETTE SMOKING IS THE LEADING RISK FACTOR, A GROWING NUMBER OF GENETIC VARIATIONS HAVE BEEN DISCOVERED TO INFLUENCE DISEASE SUSCEPTIBILITY. EPIGENETIC MODIFICATIONS MAY MEDIATE THE RESPONSE OF THE GENOME TO SMOKING AND REGULATE GENE EXPRESSION. CHROMOSOME 19Q13.2 REGION IS ASSOCIATED WITH BOTH SMOKING AND COPD, YET ITS FUNCTIONAL ROLE IS UNCLEAR. OUR STUDY AIMED TO DETERMINE WHETHER RS7937 (RAB4B, EGLN2), A TOP GENETIC VARIANT IN 19Q13.2 REGION IDENTIFIED IN GENOME-WIDE ASSOCIATION STUDIES OF COPD, IS ASSOCIATED WITH DIFFERENTIAL DNA METHYLATION IN BLOOD (N = 1490) AND GENE EXPRESSION IN BLOOD (N = 721) AND LUNGS (N = 1087). WE COMBINED GENETIC AND EPIGENETIC DATA FROM THE ROTTERDAM STUDY (RS) TO PERFORM THE EPIGENOME-WIDE ASSOCIATION ANALYSIS OF RS7937. FURTHER, WE USED GENETIC AND TRANSCRIPTOMIC DATA FROM BLOOD (RS) AND FROM LUNG TISSUE (LUNG EXPRESSION QUANTITATIVE TRAIT LOCI MAPPING STUDY), TO PERFORM THE TRANSCRIPTOME-WIDE ASSOCIATION STUDY OF RS7937. RS7937 WAS SIGNIFICANTLY (FDR < 0.05) AND CONSISTENTLY ASSOCIATED WITH DIFFERENTIAL DNA METHYLATION IN BLOOD AT 4 CPG SITES IN CIS, INDEPENDENT OF SMOKING. ONE METHYLATION SITE (CG11298343-EGLN2) WAS ALSO ASSOCIATED WITH COPD (P = 0.001). ADDITIONALLY, RS7937 WAS ASSOCIATED WITH GENE EXPRESSION LEVELS IN BLOOD IN CIS (EGLN2), 42% MEDIATED THROUGH CG11298343, AND IN LUNG TISSUE, IN CIS AND TRANS (NUMBL, EGLN2, DNMT3A, LOC101929709 AND PAK2). OUR RESULTS SUGGEST THAT CHANGES OF DNA METHYLATION AND GENE EXPRESSION MAY BE INTERMEDIATE STEPS BETWEEN GENETIC VARIANTS AND COPD, BUT FURTHER CAUSAL STUDIES IN LUNG TISSUE SHOULD CONFIRM THIS HYPOTHESIS.	2018	
                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                     
16 6484  20 TOXICOLOGIC PROFILE OF ACRYLONITRILE. ACRYLONITRILE IS A MONOMER USED EXTENSIVELY AS A RAW MATERIAL IN THE MANUFACTURING OF ACRYLIC FIBERS, PLASTICS, SYNTHETIC RUBBERS, AND ACRYLAMIDE. IT HAS BEEN CLASSIFIED AS A PROBABLE HUMAN CARCINOGEN ACCORDING TO THE RESULTS OF NUMEROUS CHRONIC RAT BIOASSAYS. THE PRESENT REPORT SUMMARIZES THE TOXICITY DATA ON ACRYLONITRILE AND REVIEWS AVAILABLE DATA CONCERNING THE MECHANISM (GENETIC VERSUS EPIGENETIC) BY WHICH ACRYLONITRILE IS CARCINOGENIC IN RATS. FROM THE EVALUATION OF THE RELEVANT TOXICITY DATA, IT CAN BE CONCLUDED THAT ACRYLONITRILE IS INDEED CARCINOGENIC TO RATS AFTER EITHER ORAL OR INHALATIONAL EXPOSURE. HOWEVER, INFORMATION ON OTHER MAMMALIAN SPECIES IS LACKING, AND, MOREOVER, THE EXACT MECHANISM OF THE CARCINOGENIC PROCESS IS UNCLEAR. THEREFORE, IT IS RECOMMENDED TO CONDUCT AN ADDITIONAL LONG-TERM INHALATION CARCINOGENICITY STUDY WITH ACRYLONITRILE IN MICE, AS WELL AS STUDIES INTO THE MECHANISM BY WHICH ACRYLONITRILE INDUCES (BRAIN) TUMORS IN RATS (GENETIC VERSUS EPIGENETIC).	1998	
                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                    
17 3074  27 GENOME-WIDE DNA METHYLOME AND TRANSCRIPTOME CHANGES INDUCED BY INORGANIC NANOPARTICLES IN HUMAN KIDNEY CELLS AFTER CHRONIC EXPOSURE. THE UNIQUE PHYSICOCHEMICAL PROPERTIES MAKE INORGANIC NANOPARTICLES (INPS) AN EXCITING TOOL IN DIAGNOSIS AND DISEASE MANAGEMENT. HOWEVER, AS INPS ARE RELATIVELY DIFFICULT TO FULLY DEGRADE AND EXCRETE, THEIR UNINTENDED ACCUMULATION IN THE TISSUE MIGHT RESULT IN ADVERSE HEALTH EFFECTS. HEREIN, WE PROVIDE A METHYLOME-TRANSCRIPTOME FRAMEWORK FOR CHRONIC EFFECTS OF INPS, COMMONLY USED IN BIOMEDICAL APPLICATIONS, IN HUMAN KIDNEY TH-1 CELLS. RENAL CLEARANCE IS ONE OF THE MOST IMPORTANT ROUTES OF NANOPARTICLE EXCRETION; THEREFORE, A DETAILED EVALUATION OF NANOPARTICLE-MEDIATED NEPHROTOXICITY IS AN IMPORTANT TASK. INTEGRATED ANALYSIS OF METHYLOME AND TRANSCRIPTOME CHANGES INDUCED BY INPS (PEG-AUNPS, FE(3)O(4)NPS, SIO(2)NPS, AND TIO(2)NPS) REVEALED SIGNIFICANTLY DEREGULATED GENES WITH FUNCTIONAL CLASSIFICATION IN IMMUNE RESPONSE, DNA DAMAGE, AND CANCER-RELATED PATHWAYS. ALTHOUGH MOST DEREGULATED GENES WERE UNIQUE TO INDIVIDUAL INPS, A RELATIVELY HIGH PROPORTION OF THEM ENCODED THE TRANSCRIPTION FACTORS. INTERESTINGLY, FOS HYPERMETHYLATION INVERSELY CORRELATING WITH GENE EXPRESSION WAS ASSOCIATED WITH ALL INPS EXPOSURES. OUR STUDY EMPHASIZES THE NEED FOR A MORE COMPREHENSIVE INVESTIGATION OF INPS' BIOLOGICAL SAFETY, ESPECIALLY AFTER CHRONIC EXPOSURE.	2022	
                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                  
18 1448  26 DIPEPTIDYL PEPTIDASE-4 INHIBITION AND NARROW-BAND ULTRAVIOLET-B LIGHT IN PSORIASIS (DINUP): STUDY PROTOCOL FOR A RANDOMISED CONTROLLED TRIAL. BACKGROUND: MODERATE TO SEVERE PSORIASIS IS A SYSTEMIC INFLAMMATORY DISEASE ASSOCIATED WITH INSULIN RESISTANCE, OBESITY AND TYPE 2 DIABETES (T2DM). SITAGLIPTIN IS A DIPEPTIDYL PEPTIDASE-4 (DPP-4) INHIBITOR THAT IMPROVES GLYCAEMIA AND HAS A MARKETING AUTHORISATION FOR THE TREATMENT OF T2DM. NON-IMMUNOSUPPRESSIVE THERAPIES THAT ARE EFFECTIVE FOR PSORIASIS AND ITS ASSOCIATED COMORBIDITIES WOULD BE A SIGNIFICANT ADVANCE IN THE TREATMENT OF THIS CHRONIC DISEASE. METHODS/DESIGN: THIS IS A SINGLE CENTRE, 39-WEEK, PROSPECTIVE, RANDOMISED, OPEN LABEL, CLINICAL TRIAL OF ORAL SITAGLIPTIN (JANUVIA((R))) IN PSORIASIS PATIENTS WHO ARE DUE TO UNDERGO A COURSE OF NARROW-BAND ULTRAVIOLET-B (NB-UVB) PHOTOTHERAPY. WE PLAN TO ENROL 120 PARTICIPANTS AND ALLOCATE PARTICIPANTS ON A RANDOM AND 1:1 BASIS TO RECEIVE SITAGLIPTIN 100 MG DAILY FOR 24 WEEKS COMBINED WITH NB-UVB OR NB-UVB MONOTHERAPY. PARTICIPANTS WILL BE FOLLOWED UP FOR 12 WEEKS AFTER SITAGLIPTIN THERAPY IS DISCONTINUED. THE PRIMARY ENDPOINT IS THE CHANGE IN PSORIASIS AREA AND SEVERITY INDEX (PASI) 24 WEEKS AFTER TREATMENT INITIATION. SECONDARY ENDPOINTS INCLUDE CUMULATIVE NB-UVB DOSE, NUMBER OF NB-UVB TREATMENTS REQUIRED TO CLEAR PSORIASIS, PROPORTIONS OF PARTICIPANTS WHO ACHIEVE PASI-50 (50 % REDUCTION IN PASI FROM BASELINE), PASI-75, PASI-90 AND THE PROPORTION OF PARTICIPANTS WHO RELAPSE IN EACH GROUP. WE WILL ALSO ANALYSE CHANGES IN CARDIOVASCULAR DISEASE RISK FACTORS, SERUM CYTOKINE AND HORMONE LEVELS AND PERIPHERAL BLOOD MONONUCLEAR EXPRESSION OF IMMUNE PROTEINS AT 24 AND 36 WEEKS. A SUBGROUP OF PARTICIPANTS WILL HAVE SKIN BIOPSIES TAKEN AND ANALYSED FOR SKIN LEVELS AND EXPRESSION OF IMMUNE CELLS, RECEPTORS, HORMONES AND IMMUNE PROTEINS. THE GENETIC OR EPIGENETIC PROFILE THAT PREDICTS BEST RESPONSE TO DPP-4 INHIBITOR THERAPY WILL BE ANALYSED. THE SAFETY ENDPOINTS INCLUDE THE RATE AND SEVERITY OF ADVERSE EVENTS. DISCUSSION: THIS IS THE FIRST RANDOMISED CLINICAL TRIAL ASSESSING DIPEPTIDYL PEPTIDASE-4 INHIBITION THERAPY IN PSORIASIS. WE HYPOTHESISE THAT SITAGLIPTIN THERAPY IN COMBINATION WITH NB-UVB IMPROVES PSORIASIS SEVERITY COMPARED TO NB-UVB MONOTHERAPY.

19 3381  26 HLA AND AUTOIMMUNE DISEASES: TYPE 1 DIABETES (T1D) AS AN EXAMPLE. AUTOIMMUNE DISEASES NEED TO BE CONSIDERED AT A GENETIC AND MECHANISTIC LEVEL. T1D IS AN AUTOIMMUNE, CHRONIC, MULTIFACTORIAL AND POLYGENIC DISEASE CHARACTERIZED BY THE DESTRUCTION OF THE PANCREATIC BETA-CELLS ASSOCIATED WITH LONG TERM DYSFUNCTION OF SEVERAL ORGANS AND TISSUES. MECHANISMS OF SUSCEPTIBILITY INCLUDE EPI-GENETIC AND POST-TRANSCRIPTIONAL EFFECTS THAT REGULATE TRANSMISSION AND EXPRESSION OF THE INHERITED GENES. THE HLA COMPLEX, CONSTITUTES THE MOST RELEVANT REGION CONTRIBUTING 50% OF THE INHERITED RISK FOR T1D. AN ADDITIONAL 17 GENES WITH VARIABLE BUT SMALL EFFECTS HAVE BEEN DESCRIBED. IN NON-CAUCASIANS, THE PRESENCE OF E-DRBETA1-74 AND/OR D-DRBETA1-57 ARE RELEVANT IN PREDISPOSITION. THE "DIABETOGENIC HAPLOTYPES" IN MEXICANS WERE DRB1*0301-DQA1*0501-DQB1*0201 (OR = 21.4); DRB1*0405-DQA1-*0301-DQB1*0302 (OR = 44.5) AND THE SAME DQA1/DQB1 WITH DRB1*0404/*0401 CONFERRING LOWER RISK, INCREASING (OR = 61.3) WITH AN EARLY AGE AT ONSET AND A HETEROZYGOTE DR3/DR4 GENOTYPE. IN MOST POPULATIONS, THE ABSENCE OF D-57 AND THE PRESENCE OF R-52 ARE IMPORTANT TO THE SUSCEPTIBILITY, BUT IN HISPANICS, ALL DR4S (INCLUDING THE PROTECTIVE DRB1*0403/*0407/*0411) ARE IN LINKAGE DISEQUILIBRIUM WITH DQA1/DQB1 SUSCEPTIBILITY ALLELES. THUS, SUSCEPTIBILITY ALLELES IN LATIN AMERICAN MESTIZOS ARE OF MEDITERRANEAN ANCESTRY WHEREAS PROTECTIVE ALLELES ARE OF AMERINDIAN ORIGIN. IN THIS REVIEW, WE DISCUSS THE COMPLEXITY OF T1D AND SOME ASPECTS OF PREVENTION/INTERVENTION BASED ON IMMUNOGENETICS.	2006	
                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                         
20 4465  26 MOLECULAR MECHANISMS OF POSTTRAUMATIC STRESS DISORDER (PTSD) AS A BASIS FOR INDIVIDUALIZED AND PERSONALIZED THERAPY: RATIONALE, DESIGN AND METHODS OF THE SOUTH EASTERN EUROPE (SEE)-PTSD STUDY. POSTTRAUMATIC STRESS DISORDER (PTSD) IS A MAJOR HEALTH PROBLEM IN SOUTH EASTERN EUROPE (SEE). AVAILABLE TREATMENT OPTIONS ARE NOT EFFICIENT ENOUGH AND THE COURSE IS OFTEN CHRONIC. LITTLE IS KNOWN ABOUT MOLECULAR MEDIATORS AND MODERATORS OF PATHOGENESIS AND THERAPY. GENETIC AND EPIGENETIC VARIATION MAY BE ONE CENTRAL MOLECULAR MECHANISM. WE THEREFORE ESTABLISHED A CONSORTIUM COMBINING CLINICAL EXPERTISE ON PTSD FROM SEE COUNTRIES BOSNIA-HERZEGOVINA (SARAJEVO, TUZLA AND MOSTAR), KOSOVO (PRISHTINA) AND CROATIA (ZAGREB) WITH GENETIC AND EPIGENETIC COMPETENCE FROM GERMANY (WURZBURG) IN 2011 WITHIN THE FRAMEWORK OF THE DAAD (DEUTSCHER AKADEMISCHER AUSTAUSCHDIENST)-FUNDED STABILITY PACT FOR SOUTH EASTERN EUROPE. AFTER OBTAINING ETHICAL VOTES AND PERFORMING RATER TRAININGS AS WELL AS TRAINING IN DNA EXTRACTION FROM EDTA BLOOD BETWEEN 2011 AND 2013, WE RECRUITED 747 INDIVIDUALS WHO HAD EXPERIENCED WAR-RELATED TRAUMA IN THE SEE CONFLICTS BETWEEN 1991 AND 1999. 236 PARTICIPANTS HAD CURRENT PTSD, 161 LIFETIME PTSD AND 350 DID NOT HAVE AND NEVER HAD PTSD. DEMOGRAPHIC AND CLINICAL DATA ARE CURRENTLY MERGED TOGETHER WITH GENETIC AND EPIGENETIC DATA IN A SINGLE DATABASE TO ALLOW FOR A COMPREHENSIVE ANALYSIS OF THE ROLE OF GENETIC AND EPIGENETIC VARIATION IN THE PATHOGENESIS AND THERAPY OF PTSD. ANALYSES WILL BE DONE TO A GREAT DEGREE BY PHD STUDENTS FROM PARTICIPATING SEE CENTERS WHO IN ADDITION TO PARTICIPATION IN THE PROJECT HAD AN OPPORTUNITY TO TAKE PART IN SPRING AND SUMMER SCHOOLS OF THE DFG (DEUTSCHE FORSCHUNGSGEMEINSCHAFT) FUNDED RESEARCH TRAINING GROUP (RTG) 1253 AND THUS MEET PHD STUDENTS FROM GERMANY AND OTHER COUNTRIES WE ARE CONFIDENT THAT OUR PROJECT WILL NOT ONLY CONTRIBUTE TO A BETTER UNDERSTANDING OF GENETIC AND EPIGENETIC MECHANISMS OF PTSD AS A BASIS FOR FUTURE INDIVIDUALIZED AND PERSONALIZED THERAPIES, BUT ALSO TO THE ACADEMIC DEVELOPMENT OF SOUTH EASTERN EUROPE.	2016
