1  4015 162 LOW-DOSE EXPOSURE TO BISPHENOLS A, F AND S OF HUMAN PRIMARY ADIPOCYTE IMPACTS CODING AND NON-CODING RNA PROFILES. BISPHENOL A (BPA) EXPOSURE HAS BEEN SUSPECTED TO BE ASSOCIATED WITH DELETERIOUS EFFECTS ON HEALTH INCLUDING OBESITY AND METABOLICALLY-LINKED DISEASES. ALTHOUGH BISPHENOLS F (BPF) AND S (BPS) ARE BPA STRUCTURAL ANALOGS COMMONLY USED IN MANY MARKETED PRODUCTS AS A REPLACEMENT FOR BPA, ONLY SPARSE TOXICOLOGICAL DATA ARE AVAILABLE YET. OUR OBJECTIVE WAS TO COMPREHENSIVELY CHARACTERIZE BISPHENOLS GENE TARGETS IN A HUMAN PRIMARY ADIPOCYTE MODEL, IN ORDER TO DETERMINE WHETHER THEY MAY INDUCE CELLULAR DYSFUNCTION, USING CHRONIC EXPOSURE AT TWO CONCENTRATIONS: A "LOW-DOSE" SIMILAR TO THE DOSE USUALLY ENCOUNTERED IN HUMAN BIOLOGICAL FLUIDS AND A HIGHER DOSE. THEREFORE, BPA, BPF AND BPS HAVE BEEN ADDED AT 10 NM OR 10 MUM DURING THE DIFFERENTIATION OF HUMAN PRIMARY ADIPOCYTES FROM SUBCUTANEOUS FAT OF THREE NON-DIABETIC CAUCASIAN FEMALE PATIENTS. GENE EXPRESSION (MRNA/LNCRNA) ARRAYS AND MICRORNA ARRAYS, HAVE BEEN USED TO ASSESS CODING AND NON-CODING RNA CHANGES. WE DETECTED SIGNIFICANTLY DEREGULATED MRNA/LNCRNA AND MIRNA AT LOW AND HIGH DOSES. ENRICHMENT IN "CANCER" AND "ORGANISMAL INJURY AND ABNORMALITIES" RELATED PATHWAYS WAS FOUND IN RESPONSE TO THE THREE PRODUCTS. SOME LONG INTERGENIC NON-CODING RNAS AND SMALL NUCLEOLAR RNAS WERE DIFFERENTIALLY EXPRESSED SUGGESTING THAT BISPHENOLS MAY ALSO ACTIVATE MULTIPLE CELLULAR PROCESSES AND EPIGENETIC MODIFICATIONS. THE ANALYSIS OF UPSTREAM REGULATORS OF DEREGULATED GENES HIGHLIGHTED HORMONES OR HORMONE-LIKE CHEMICALS SUGGESTING THAT BPS AND BPF CAN BE SUSPECTED TO INTERFERE, JUST LIKE BPA, WITH HORMONAL REGULATION AND HAVE TO BE CONSIDERED AS ENDOCRINE DISRUPTORS. ALL THESE RESULTS SUGGEST THAT AS BPA, ITS SUBSTITUTES BPS AND BPF SHOULD BE USED WITH THE SAME RESTRICTIONS.	2017	
                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                             
2  5097  39 PLASTICS DERIVED ENDOCRINE-DISRUPTING COMPOUNDS AND THEIR EFFECTS ON EARLY DEVELOPMENT. DESPITE THE FACT THAT THE ESTROGENIC EFFECTS OF BISPHENOLS WERE FIRST DESCRIBED 80 YEARS AGO, RECENT DATA ABOUT ITS POTENTIAL NEGATIVE IMPACT ON BIRTH OUTCOME PARAMETERS RAISES A STRONG RATIONALE TO INVESTIGATE FURTHER. THE ADVERSE HEALTH EFFECTS OF PLASTICS RECOMMEND TO MEASURE THE IMPACTS OF ENDOCRINE-DISRUPTING COMPOUNDS (EDCS) SUCH AS BISPHENOLS (BPA, BPS, BPF), BIS(2-ETHYLHEXYL) PHTHALATE, AND DIBUTYL PHTHALATE (DBP) IN HUMAN HEALTH. EXPOSURE TO THESE COMPOUNDS IN UTERO MAY PROGRAM THE DISEASES OF THE TESTIS, PROSTATE, KIDNEY AND ABNORMALITIES IN THE IMMUNE SYSTEM, AND CAUSE TUMORS, UTERINE HEMORRHAGE DURING PREGNANCY AND POLYCYSTIC OVARY. THESE COMPOUNDS ALSO CONTROL THE PROCESSES OF EPIGENETIC TRANSGENERATIONAL INHERITANCE OF ADULT-ONSET DISEASES BY MODULATING DNA METHYLATION AND EPIMUTATIONS IN REPRODUCTIVE CELLS. THE EARLY DEVELOPMENTAL STAGE IS THE MOST SUSCEPTIBLE WINDOW FOR DEVELOPMENTAL AND GENOMIC PROGRAMMING. THE CRITICAL STAGES OF THE EVENTS FOR A NORMAL HUMAN BIRTH LIE BETWEEN THE MANY TRANSITIONS OCCURRING BETWEEN SPERMATOGENESIS, EGG FERTILIZATION AND THE FULLY FORMED FETUS. AS THE CELLS BEGIN TO GROW AND DIFFERENTIATE, THERE ARE CRITICAL BALANCES OF HORMONES, AND PROTEIN SYNTHESIS. DATA ARE EMERGING ON HOW THESE PLASTIC-DERIVED COMPOUNDS AFFECT EMBRYOGENESIS, PLACENTATION AND FETO-PLACENTAL DEVELOPMENT SINCE PREGNANT WOMEN AND UNBORN FETUSES ARE OFTEN EXPOSED TO THESE FACTORS DURING PRECONCEPTION AND THROUGHOUT GESTATION. IMPAIRED EARLY DEVELOPMENT THAT ULTIMATELY INFLUENCES FETAL OUTCOMES IS AT THE CENTER OF MANY DEVELOPMENTAL DISORDERS AND CONTRIBUTES AN INDEPENDENT RISK FACTOR FOR ADULT CHRONIC DISEASES. THIS REVIEW WILL SUMMARIZE THE CURRENT STATUS ON THE IMPACT OF EXPOSURE TO PLASTIC DERIVED EDCS ON THE GROWTH, GENE EXPRESSION, EPIGENETIC AND ANGIOGENIC ACTIVITIES OF THE EARLY FETAL DEVELOPMENT PROCESS AND THEIR POSSIBLE EFFECTS ON BIRTH OUTCOMES.	2020	
                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                           
3   654  54 BISPHENOL S INDUCED EPIGENETIC AND TRANSCRIPTIONAL CHANGES IN HUMAN BREAST CANCER CELL LINE MCF-7. IN RECENT YEARS, CONCERNS ABOUT USING BISPHENOL A (BPA) IN DAILY CONSUME PRODUCTS AND ITS EFFECTS IN MANY CHRONIC HUMAN DISEASES HAVE PROMPTED THE REMOVAL OF BPA. HOWEVER, THE WIDELY USED BPA ALTERNATIVES, INCLUDING BISPHENOL S (BPS), HAVE A HIGH STRUCTURAL SIMILARITY WITH BPA, SUGGESTING THAT THEY MAY HAVE SIMILAR BIOLOGICAL EFFECTS TOWARDS HUMAN BEINGS. INDEED, BPS WAS ALSO FOUND TO HAVE ENDOCRINE-DISRUPTING EFFECTS. EPIGENETIC MECHANISM WAS REPORTED TO BE INVOLVED IN BPA-INDUCED BIOLOGICAL EFFECTS IN BOTH IN VITRO AND IN VIVO MODELS. HOWEVER, THERE IS NO ASSESSMENT ON WHETHER BPS COULD CAUSE EPIGENETIC CHANGES. IN THIS WORK, WE INVESTIGATED THE POSSIBLE EPIGENETIC EFFECTS OF BPS THAT MIGHT INDUCE IN HUMAN BREAST CANCER CELL LINE MCF-7. WE FOUND THAT BPS COULD CHANGE DNA METHYLATION LEVEL OF TRANSPOSONS. BESIDES, METHYLATION STATUS IN PROMOTER OF BREAST CANCER RELATED GENES CDH1, SFN, TNFRSF10C WERE ALSO CHANGED, WHICH IMPLIED THAT BPS MIGHT PLAY A ROLE IN THE DEVELOPMENT OF BREAST CANCER. GENE EXPRESSION PROFILING SHOWED THAT SOME GENES RELATED TO BREAST CANCER PROGRESSION WERE UPREGULATED, INCLUDING THBS4, PPARGC1A, CREB5, COL5A3. GENE ONTOLOGY (GO) ANALYSIS OF THE DIFFERENTIALLY EXPRESSED GENES REVEALED THE SIGNIFICANTLY CHANGES IN PI3K-AKT SIGNALING PATHWAY AND EXTRACELLULAR MATRIX, WHICH WERE RELATED TO THE PROLIFERATION, MIGRATION AND INVASION OF BREAST CANCER CELLS. THESE RESULTS ILLUSTRATED THAT BPS EXPOSURE MIGHT PLAY ROLES IN THE PROGRESSION OF BREAST CANCER.	2019	
                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                         
4   653  29 BISPHENOL A, HYPERTENSION, AND CARDIOVASCULAR DISEASES: EPIDEMIOLOGICAL, LABORATORY, AND CLINICAL TRIAL EVIDENCE. BISPHENOL A (BPA) EXPOSURE HAS BECOME ONE OF THE MOST COMMON ENVIRONMENTAL CHEMICAL EXPOSURES IN HUMANS. THERE IS GROWING EVIDENCE REGARDING AN ASSOCIATION BETWEEN BPA EXPOSURE, HYPERTENSION, AND CARDIOVASCULAR DISEASES (CVD). IF BPA EXPOSURE IS INDEED ASSOCIATED WITH RAISED BLOOD PRESSURE AND CVD, IT WOULD BE A MAJOR PUBLIC HEALTH PROBLEM. THEREFORE, WE REVIEWED THE EPIDEMIOLOGICAL, LABORATORY, AND CLINICAL TRIAL EVIDENCE FOR AN ASSOCIATION BETWEEN BPA EXPOSURE, CVD, AND HYPERTENSION, AND DISCUSSED THE POSSIBLE MECHANISMS IN THIS ARTICLE. CROSS-SECTIONAL STUDIES IN VARIOUS ETHNICITIES SUGGESTED A POSSIBLE ASSOCIATION BETWEEN BPA EXPOSURE AND HYPERTENSION; THIS ASSOCIATION WAS SUPPORTED BY A PANEL STUDY AND A RANDOMIZED CLINICAL TRIAL. DESPITE THE DISCORDANCE AMONG CROSS-SECTIONAL STUDIES ABOUT AN ASSOCIATION BETWEEN BPA EXPOSURE AND CVD, A LONGITUDINAL STUDY SHOWS THAT BPA EXPOSURE IS A RISK FACTOR FOR CVD. THE EFFECTS OF BPA EXPOSURE SUCH AS ENDOCRINAL DISTURBANCE, INDUCTION OF OXIDATIVE STRESS AND INFLAMMATION, EPIGENETIC CHANGE, AND LINKS WITH OTHER CHRONIC DISEASES MAY HIGHLIGHT A POSSIBLE MECHANISM BETWEEN BPA EXPOSURE, CVD, AND HYPERTENSION. TO CLARIFY THE CAUSAL RELATIONSHIP, WELL-DESIGNED STUDIES ARE NEEDED IN THE FUTURE.	2016	
                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                               
5  6338  31 THE ROLE OF ENDOCRINE-DISRUPTING CHEMICALS IN UTERINE FIBROID PATHOGENESIS. PURPOSE OF REVIEW: UTERINE LEIOMYOMA (FIBROIDS) IS A GYNECOLOGIC DISORDER IMPACTING THE MAJORITY OF WOMEN IN THE UNITED STATES. WHEN SYMPTOMATIC, THESE NONCANCEROUS TUMORS CAN CAUSE SEVERE MORBIDITY INCLUDING PELVIC PAIN, MENORRHAGIA, AND INFERTILITY. ENDOCRINE-DISRUPTING CHEMICALS (EDCS) MAY REPRESENT A MODIFIABLE RISK FACTOR. THE AIM OF THIS REVIEW IS TO SUMMARIZE RECENT HUMAN AND EXPERIMENTAL EVIDENCE ON EDCS EXPOSURES AND FIBROIDS. RECENT FINDINGS: MULTIPLE EDCS ARE ASSOCIATED WITH FIBROID OUTCOMES AND/OR PROCESSES INCLUDING PHTHALATES, PARABENS, ENVIRONMENTAL PHENOLS, ALTERNATE PLASTICIZERS, DIETHYLSTILBESTROL, ORGANOPHOSPHATE ESTERS, AND TRIBUTYLTIN. EPIDEMIOLOGIC STUDIES SUGGEST EXPOSURE TO CERTAIN EDCS, SUCH AS DI-(2-ETHYLHXYL)-PHTHALATE (DEHP), ARE ASSOCIATED WITH INCREASED FIBROID RISK AND SEVERITY. BOTH HUMAN AND EXPERIMENTAL STUDIES INDICATE THAT EPIGENETIC PROCESSES MAY PLAY AN IMPORTANT ROLE IN LINKING EDCS TO FIBROID PATHOGENESIS. IN-VITRO AND IN-VIVO STUDIES SHOW THAT DEHP, BISPHENOL A, AND DIETHYLSTILBESTROL CAN IMPACT BIOLOGICAL PATHWAYS CRITICAL TO FIBROID PATHOGENESIS. SUMMARY: WHILE RESEARCH ON EDCS AND FIBROIDS IS STILL EVOLVING, RECENT EVIDENCE SUGGESTS EDC EXPOSURES MAY CONTRIBUTE TO FIBROID RISK AND PROGRESSION. FURTHER RESEARCH IS NEEDED TO EXAMINE THE IMPACTS OF EDC MIXTURES AND TO IDENTIFY CRITICAL BIOLOGICAL PATHWAYS AND WINDOWS OF EXPOSURE. THESE RESULTS COULD OPEN THE DOOR TO NEW PREVENTION STRATEGIES FOR FIBROIDS.	2020	
                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                          
6  6384  43 THE ROLE OF POLYCARBONATE MONOMER BISPHENOL-A IN INSULIN RESISTANCE. BISPHENOL A (BPA) IS A SYNTHETIC UNIT OF POLYCARBONATE POLYMERS AND EPOXY RESINS, THE TYPES OF PLASTICS THAT COULD BE FOUND IN ESSENTIALLY EVERY HUMAN POPULATION AND INCORPORATED INTO ALMOST EVERY ASPECT OF THE MODERN HUMAN SOCIETY. BPA POLYMERS APPEAR IN A WIDE RANGE OF PRODUCTS, FROM LIQUID STORAGES (PLASTIC BOTTLES, CAN AND GLASS LININGS, WATER PIPES AND TANKS) AND FOOD STORAGES (PLASTICS WRAPS AND CONTAINERS), TO MEDICAL AND DENTAL DEVICES. BPA POLYMERS COULD BE HYDROLYZED SPONTANEOUSLY OR IN A PHOTO- OR TEMPERATURE-CATALYZED PROCESS, PROVIDING WIDESPREAD ENVIRONMENTAL DISTRIBUTION AND CHRONIC EXPOSURE TO THE BPA MONOMER IN CONTEMPORARY HUMAN POPULATIONS. BISPHENOL A IS ALSO A XENOESTROGEN, AN ENDOCRINE-DISRUPTING CHEMICAL (EDC) THAT INTERFERES WITH THE ENDOCRINE SYSTEM MIMICKING THE EFFECTS OF AN ESTROGEN AND COULD POTENTIALLY KEEP OUR ENDOCRINE SYSTEM IN A CONSTANT PERTURBATION THAT PARALLELS ENDOCRINE DISRUPTION ARISING DURING PREGNANCY, SUCH AS INSULIN RESISTANCE (IR). GESTATIONAL INSULIN RESISTANCE REPRESENTS A NATURAL BIOLOGICAL PHENOMENON OF HIGHER INSULIN RESISTANCE IN PERIPHERAL TISSUES OF THE PREGNANT FEMALES, WHEN NUTRIENTS ARE INCREASINGLY BEING DIRECTED TO THE EMBRYO INSTEAD OF BEING STORED IN PERIPHERAL TISSUES. GESTATIONAL DIABETES MELLITUS MAY APPEAR IN HEALTHY NON-DIABETIC FEMALES, DUE TO GESTATIONAL INSULIN RESISTANCE THAT LEADS TO INCREASED BLOOD SUGAR LEVELS AND HYPERINSULINEMIA (INCREASED INSULIN PRODUCTION FROM THE PANCREATIC BETA CELLS). THE HYPOTHESIS STATES THAT UNNOTICED AND CONSTANT EXPOSURE TO THIS ENVIRONMENTAL CHEMICAL MIGHT POTENTIALLY LEAD TO THE FORMATION OF CHRONIC LOW-LEVEL ENDOCRINE DISRUPTIVE STATE THAT RESEMBLES GESTATIONAL INSULIN RESISTANCE, WHICH MIGHT CONTRIBUTE TO THE DEVELOPMENT OF DIABETES. THE INCREASING BODY OF EVIDENCE SUPPORTS THE MAJOR PREMISES OF THIS HYPOTHESIS, AS EXEMPLIFIED BY THE NUMEROUS PUBLICATIONS EXAMINING THE ASSOCIATION OF BPA AND INSULIN RESISTANCE, BOTH EPIDEMIOLOGICAL AND MECHANISTIC. HOWEVER, TO WHAT EXTENT BPA MIGHT CONTRIBUTE TO THE DEVELOPMENT OF DIABETES IN THE MODERN SOCIETIES STILL REMAINS UNKNOWN. IN THIS REVIEW, I DISCUSS THE CHEMICAL PROPERTIES OF BPA AND THE SOURCES OF BPA CONTAMINATION FOUND IN THE ENVIRONMENT AND IN HUMAN TISSUES. I PROVIDE AN OVERVIEW OF MECHANISMS FOR THE PROPOSED ROLE OF BISPHENOL A IN INSULIN RESISTANCE AND DIABETES, AS WELL AS OTHER RELATED DISEASES, SUCH AS CARDIOVASCULAR DISEASES. I DESCRIBE THE TRANSMISSION OF BPA EFFECTS TO THE OFFSPRING AND POSTULATE THAT GENDER RELATED DIFFERENCES MIGHT ORIGINATE FROM DIFFERENCES IN LIVER ENZYME LEVELS, SUCH AS UDP-GLUCURONOSYLTRANSFERASE, WHICH IS INVOLVED IN BPA PROCESSING AND ITS ELIMINATION FROM THE ORGANISM. I DISCUSS THE MOLECULAR MECHANISMS OF BPA ACTION THROUGH NUCLEAR AND MEMBRANE-BOUND ER RECEPTORS, NON-MONOTONIC DOSE RESPONSE, EPIGENETIC MODIFICATIONS OF THE DNA AND PROPOSE THAT CHRONIC EXPOSURE TO WEAK BINDERS, SUCH AS BPA, MAY MIMIC THE EFFECTS OF STRONG BINDERS, SUCH AS ESTROGENS.	2017	

7  6280  49 THE PLASTICIZER BISPHENOL A PERTURBS THE HEPATIC EPIGENOME: A SYSTEMS LEVEL ANALYSIS OF THE MIRNOME. UBIQUITOUS EXPOSURE TO BISPHENOL A (BPA), AN ENDOCRINE DISRUPTOR (ED), HAS RAISED CONCERNS FOR BOTH HUMAN AND ECOSYSTEM HEALTH. EPIGENETIC FACTORS, INCLUDING MICRORNAS (MIRNAS), ARE KEY REGULATORS OF GENE EXPRESSION DURING CANCER. THE EFFECT OF BPA EXPOSURE ON THE ZEBRAFISH EPIGENOME REMAINS POORLY CHARACTERIZED. ZEBRAFISH REPRESENTS AN EXCELLENT MODEL TO STUDY CANCER AS THE ORGANISM DEVELOPS A DISEASE THAT RESEMBLES HUMAN CANCER. USING ZEBRAFISH AS A SYSTEMS TOXICOLOGY MODEL, WE HYPOTHESIZED THAT CHRONIC BPA-EXPOSURE IMPACTS THE MIRNOME IN ADULT ZEBRAFISH AND ESTABLISHES AN EPIGENOME MORE SUSCEPTIBLE TO CANCER DEVELOPMENT. AFTER A 3 WEEK EXPOSURE TO 100 NM BPA, RNA FROM THE LIVER WAS EXTRACTED TO PERFORM HIGH THROUGHPUT MRNA AND MIRNA SEQUENCING. DIFFERENTIAL EXPRESSION (DE) ANALYSES COMPARING BPA-EXPOSED TO CONTROL SPECIMENS WERE PERFORMED USING ESTABLISHED BIOINFORMATICS PIPELINES. IN THE BPA-EXPOSED LIVER, 6188 MRNAS AND 15 MIRNAS WERE DIFFERENTLY EXPRESSED (Q </= 0.1). BY ANALYZING HUMAN ORTHOLOGS OF THE DE ZEBRAFISH GENES, SIGNATURES ASSOCIATED WITH NON-ALCOHOLIC FATTY LIVER DISEASE (NAFLD), OXIDATIVE PHOSPHORYLATION, MITOCHONDRIAL DYSFUNCTION AND CELL CYCLE WERE UNCOVERED. CHRONIC EXPOSURE TO BPA HAS A SIGNIFICANT IMPACT ON THE LIVER MIRNOME AND TRANSCRIPTOME IN ADULT ZEBRAFISH WITH THE POTENTIAL TO CAUSE ADVERSE HEALTH OUTCOMES INCLUDING CANCER.	2017	
                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                               
8    73  35 A MULTI-GENERATIONAL STUDY ON LOW-DOSE BPA EXPOSURE IN WISTAR RATS: EFFECTS ON MATERNAL BEHAVIOR, FLAVOR INTAKE AND DEVELOPMENT. BISPHENOL A (BPA) IS A COMMON ENDOCRINE DISRUPTOR FOUND AS AN ENVIRONMENTAL AND FOOD CONTAMINANT. IT EXERTS BOTH DEVELOPMENTAL AND BEHAVIORAL EFFECTS, MAINLY WHEN EXPOSURE OCCURS IN EARLY LIFE. THE AIM OF THIS STUDY WAS TO DETERMINE THE MULTI-GENERATIONAL EFFECTS OF CHRONIC, HUMAN-RELEVANT LOW-DOSE EXPOSURE TO BPA ON DEVELOPMENT, MATERNAL BEHAVIOR AND FLAVOR PREFERENCE IN WISTAR RATS. BPA WAS ORALLY ADMINISTERED AT A DAILY DOSE OF 5 MUG/KG BODY WEIGHT TO F0 PREGNANT DAMS FROM THE FIRST DAY OF GESTATION (GD 1) UNTIL THE LAST DAY OF LACTATION (LD 21), AND THEN TO F1 OFFSPRING FROM WEANING (PND 21) TO ADULTHOOD (PND 100). F2 OFFSPRING WERE NOT EXPOSED. DEVELOPMENT AND CLINICAL SIGNS OF TOXICITY WERE ASSESSED DAILY. MATERNAL BEHAVIOR WAS EVALUATED BY OBSERVING NURSING AND PUP-CARING ACTIONS, AS WELL AS "NON-MATERNAL" BEHAVIORS IN F0 AND F1 DAMS FROM PARTURITION UNTIL LD 8. THE FLAVOR PREFERENCES OF F1 AND F2 OFFSPRING WERE EVALUATED BASED ON THE INTAKE OF SWEET, SALT AND FAT SOLUTIONS USING THE TWO-BOTTLE CHOICE TEST ON PND 21-34 AND PND 86-99. BPA EXPOSURE: 1) DECREASED MATERNAL BEHAVIOR IN F1 DAMS, 2) CAUSED DEVELOPMENTAL DEFECTS IN BOTH F1 AND F2 OFFSPRING, WITH A NOTICEABLE DECREASE IN ANOGENITAL DISTANCE IN MALE RATS, AND 3) DID NOT AFFECT FLAVORED SOLUTION INTAKE IN F1, BUT INDUCED CHANGES IN SWEET PREFERENCE IN F2 JUVENILES AND IN SALT AND FAT SOLUTION INTAKES IN F2 ADULTS, AND 4) INDUCED A BODY WEIGHT INCREASE IN THE F2 GENERATION ONLY, WHEREAS FOOD INTAKE AND WATER CONSUMPTION DID NOT CHANGE. TAKEN AS A WHOLE, OUR FINDINGS SHOWED THAT BOTH GESTATIONAL (F0) AND LIFELONG (F1) EXPOSURES TO A HUMAN-RELEVANT DOSE OF BPA COULD INDUCE MULTI-GENERATIONAL EFFECTS ON BOTH DEVELOPMENT AND BEHAVIOR. THESE RESULTS SUGGEST POSSIBLE SELECTIVE NEUROENDOCRINE DEFECTS AND/OR EPIGENETIC CHANGES CAUSED BY BPA EXPOSURE.	2014	
                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                       
9   899  36 CHRONIC EXPOSURE TO A LOW CONCENTRATION OF BISPHENOL A DURING FOLLICLE CULTURE AFFECTS THE EPIGENETIC STATUS OF GERMINAL VESICLES AND METAPHASE II OOCYTES. OBJECTIVE: TO DETERMINE WHETHER EXPOSURE TO LOW CONCENTRATIONS OF THE ENDOCRINE DISRUPTING CHEMICAL BISPHENOL A (BPA) DURING FOLLICLE CULTURE AND OOCYTE GROWTH ALTERS THE METHYLATION STATUS OF DIFFERENTIALLY METHYLATED REGIONS (DMRS) OF IMPRINTED GENES AND HISTONE POSTTRANSLATIONAL MODIFICATION PATTERNS IN MAMMALIAN OOCYTES. DESIGN: COMPARATIVE AND CONTROL STUDY. SETTING: EXPERIMENTAL LABORATORY. ANIMAL(S): C57/BL6JXCBA/CA MICE. INTERVENTION(S): EXPOSURE OF OOCYTES TO 3 NM OR 300 NM BPA DURING FOLLICLE CULTURE FROM PREANTRAL TO ANTRAL STAGE. MAIN OUTCOME MEASURE(S): METHYLATION STATUS OF DMRS OF MATERNALLY IMPRINTED (SNRPN, IGF2R, AND MEST) AND PATERNALLY IMPRINTED GENE(S) (H19) IN MOUSE GERMINAL VESICLE OOCYTES; TRIMETHYLATION OF HISTONE H3K9, ACETYLATION OF HISTONE H4K12, AND DISTANCE BETWEEN CENTROMERES OF SISTER CHROMATIDS IN METAPHASE II OOCYTES. RESULT(S): EXPOSURE TO 3 NM BPA WAS ASSOCIATED WITH SLIGHTLY ACCELERATED FOLLICLE DEVELOPMENT, STATISTICALLY SIGNIFICANT INCREASES IN ALLELE METHYLATION ERRORS IN DMRS OF MATERNALLY IMPRINTED GENES, AND STATISTICALLY SIGNIFICANT DECREASES IN HISTONE H3K9 TRIMETHYLATION AND INTERKINETOCHORE DISTANCE. CONCLUSION(S): THE DISTURBANCES IN OOCYTE GENOMIC IMPRINTING AND MODIFICATION OF POSTTRANSLATIONAL HISTONE AND CENTROMERE ARCHITECTURE PROVIDE THE FIRST LINK BETWEEN LOW BPA EXPOSURES AND INDUCTION OF EPIGENETIC CHANGES THAT MAY CONTRIBUTE TO CHROMOSOME CONGRESSION FAILURES AND MEIOTIC ERRORS, AND TO ALTERED GENE EXPRESSION THAT MIGHT AFFECT HEALTH OF THE OFFSPRING.	2013	
                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                          
10  1825  27 EFFECTS OF HIGH-DOSE BISPHENOL A ON THE MOUSE ORAL MUCOSA: A POSSIBLE LINK WITH ORAL CANCERS. BISPHENOL A (BPA) IS AN ENDOCRINE DISRUPTING CHEMICAL ABLE TO PROMOTE HORMONE-RESPONSIVE TUMORS. THE MAJOR ROUTE OF BPA CONTAMINATION BEING ORAL, THE AIM OF THE PRESENT STUDY WAS TO INVESTIGATE BPA EFFECTS ON ORAL CELLS. HERE, WE EVALUATED THE IMPACT OF SUB-CHRONIC IN VIVO EXPOSURE TO BPA AND ITS IN VITRO EFFECTS ON NEOPLASTIC AND NON-NEOPLASTIC ORAL CELLS. WE EVALUATED THE ORAL MUCOSA OF MICE CHRONICALLY EXPOSED TO BPA (200 MG/L). THE RESPONSE OF KERATINOCYTES (NOK-SI) AND HEAD AND NECK (HN) SQUAMOUS CELL CARCINOMA (SCC), HN12 AND HN13 CELL LINES TO BPA WAS EXAMINED. IN VIVO, BPA ACCUMULATED IN ORAL TISSUES AND CAUSED AN INCREASE IN EPITHELIAL PROLIFERATIVE ACTIVITY. BPA DISRUPTED THE FUNCTION OF KERATINOCYTES BY ALTERING PRO-SURVIVAL AND PROLIFERATIVE PATHWAYS AND THE SECRETION OF CYTOKINES AND GROWTH FACTORS. IN TUMOR CELLS, BPA INDUCED PROLIFERATIVE, INVASIVE, PRO-ANGIOGENIC, AND EPIGENETIC PATHS. OUR DATA HIGHLIGHT THE HARMFUL EFFECTS OF BPA ON ORAL MUCOSA AND, TUMORIGENIC AND NON-TUMORIGENIC CELLS. ADDITIONALLY, BPA MAY BE A MODIFIER OF ORAL CANCER CELL BEHAVIOR BY PROMPTING A FUNCTIONAL SHIFT TO A MORE AGGRESSIVE PHENOTYPE.	2021	
                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                        
11  4541  44 MULTISYSTEMIC ALTERATIONS IN HUMANS INDUCED BY BISPHENOL A AND PHTHALATES: EXPERIMENTAL, EPIDEMIOLOGICAL AND CLINICAL STUDIES REVEAL THE NEED TO CHANGE HEALTH POLICIES. A VAST AMOUNT OF EVIDENCE INDICATES THAT BISPHENOL A (BPA) AND PHTHALATES ARE WIDELY DISTRIBUTED IN THE ENVIRONMENT SINCE THESE COMPOUNDS ARE MASS-PRODUCED FOR THE MANUFACTURE OF PLASTICS AND PLASTICIZERS. THESE COMPOUNDS BELONG TO A LARGE GROUP OF SUBSTANCES TERMED ENDOCRINE-DISRUPTING CHEMICALS (EDC). IT IS WELL KNOWN THAT HUMANS AND LIVING ORGANISMS ARE UNAVOIDABLY AND UNINTENTIONALLY EXPOSED TO BPA AND PHTHALATES FROM FOOD PACKAGING MATERIALS AND MANY OTHER EVERYDAY PRODUCTS. BPA AND PHTHALATES EXERT THEIR EFFECT BY INTERFERING WITH HORMONE SYNTHESIS, BIOAVAILABILITY, AND ACTION, THEREBY ALTERING CELLULAR PROLIFERATION AND DIFFERENTIATION, TISSUE DEVELOPMENT, AND THE REGULATION OF SEVERAL PHYSIOLOGICAL PROCESSES. IN FACT, THESE EDC CAN ALTER FETAL PROGRAMMING AT AN EPIGENETIC LEVEL, WHICH CAN BE TRANSGENERATIONAL TRANSMITTED AND MAY BE INVOLVED IN THE DEVELOPMENT OF VARIOUS CHRONIC PATHOLOGIES LATER IN THE ADULTHOOD, INCLUDING METABOLIC, REPRODUCTIVE AND DEGENERATIVE DISEASES, AND CERTAIN TYPES OF CANCER. IN THIS REVIEW, WE DESCRIBE THE MOST RECENT PROPOSED MECHANISMS OF ACTION OF THESE EDC AND OFFER A COMPELLING SELECTION OF EXPERIMENTAL, EPIDEMIOLOGICAL AND CLINICAL STUDIES, WHICH SHOW EVIDENCE OF HOW EXPOSURE TO THESE POLLUTANTS AFFECTS OUR HEALTH DURING DEVELOPMENT, AND THEIR ASSOCIATION WITH A WIDE RANGE OF REPRODUCTIVE, METABOLIC AND NEUROLOGICAL DISEASES, AS WELL AS HORMONE-RELATED CANCERS. WE STRESS THE IMPORTANCE OF CONCERN IN THE GENERAL POPULATION AND THE URGENT NEED FOR THE MEDICAL HEALTH CARE SYSTEM TO CLOSELY MONITOR EDC LEVELS IN THE POPULATION DUE TO UNAVOIDABLE AND INVOLUNTARY EXPOSURE TO THESE POLLUTANTS AND THEIR IMPACT ON HUMAN HEALTH.	2021	
                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                  
12   518  39 ASSOCIATIONS BETWEEN ANTIBIOTIC EXPOSURE DURING PREGNANCY, BIRTH WEIGHT AND ABERRANT METHYLATION AT IMPRINTED GENES AMONG OFFSPRING. OBJECTIVES: LOW BIRTH WEIGHT (LBW) HAS BEEN ASSOCIATED WITH COMMON ADULT-ONSET CHRONIC DISEASES, INCLUDING OBESITY, CARDIOVASCULAR DISEASE, TYPE II DIABETES AND SOME CANCERS. THE ETIOLOGY OF LBW IS MULTI-FACTORIAL. HOWEVER, RECENT EVIDENCE SUGGESTS EXPOSURE TO ANTIBIOTICS MAY ALSO INCREASE THE RISK OF LBW. THE MECHANISMS UNDERLYING THIS ASSOCIATION ARE UNKNOWN, ALTHOUGH EPIGENETIC MECHANISMS ARE HYPOTHESIZED. IN THIS STUDY, WE EVALUATED THE ASSOCIATION BETWEEN MATERNAL ANTIBIOTIC USE AND LBW AND EXAMINED THE POTENTIAL ROLE OF ALTERED DNA METHYLATION THAT CONTROLS GROWTH REGULATORY IMPRINTED GENES IN THESE ASSOCIATIONS. METHODS: BETWEEN 2009-2011, 397 PREGNANT WOMEN WERE ENROLLED AND FOLLOWED UNTIL DELIVERY. PRENATAL ANTIBIOTIC USE WAS ASCERTAINED THROUGH MATERNAL SELF-REPORT. IMPRINTED GENES METHYLATION LEVELS WERE MEASURED AT DIFFERENTIALLY METHYLATED REGIONS (DMRS) USING BISULFITE PYROSEQUENCING. GENERALIZED LINEAR MODELS WERE USED TO EXAMINE ASSOCIATIONS AMONG ANTIBIOTIC USE, BIRTH WEIGHT AND DMR METHYLATION FRACTIONS. RESULTS: AFTER ADJUSTING FOR INFANT GENDER, RACE/ETHNICITY, MATERNAL BODY MASS INDEX, DELIVERY ROUTE, GESTATIONAL WEIGHT GAIN, GESTATIONAL AGE AT DELIVERY, FOLIC ACID INTAKE, PHYSICAL ACTIVITY, MATERNAL SMOKING AND PARITY, ANTIBIOTIC USE DURING PREGNANCY WAS ASSOCIATED WITH 138 G LOWER BIRTH WEIGHT COMPARED WITH NON-ANTIBIOTIC USE (BETA-COEFFICIENT=-132.99, S.E.=50.70, P=0.008). THESE ASSOCIATIONS WERE STRONGEST IN NEWBORNS OF WOMEN WHO REPORTED ANTIBIOTIC USE OTHER THAN PENICILLINS (BETA-COEFFICIENT=-135.57, S.E.=57.38, P=0.02). METHYLATION AT FIVE DMRS, IGF2 (P=0.05), H19 (P=0.15), PLAGL1 (P=0.01), MEG3 (P=0.006) AND PEG3 (P=0.08), WAS ASSOCIATED WITH MATERNAL ANTIBIOTIC USE; AMONG THESE, ONLY METHYLATION AT THE PLAGL1 DMR WAS ALSO ASSOCIATED WITH BIRTH WEIGHT. CONCLUSION: WE REPORT AN INVERSE ASSOCIATION BETWEEN IN UTERO EXPOSURE TO ANTIBIOTICS AND LOWER INFANT BIRTH WEIGHT AND PROVIDE THE FIRST EMPIRICAL EVIDENCE SUPPORTING IMPRINTED GENE PLASTICITY IN THESE ASSOCIATIONS.	2013	
                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                 
13  4065  32 MATERNAL AND GESTATIONAL INFLUENCES ON CHILDHOOD BLOOD PRESSURE. EXPOSURES THAT CONTRIBUTE TO A SUB-OPTIMAL INTRAUTERINE ENVIRONMENT CAN HAVE AN EFFECT ON THE DEVELOPING FETUS. IMPAIRED FETAL GROWTH THAT RESULTS IN LOW BIRTH WEIGHT IS AN ESTABLISHED RISK FACTOR FOR CARDIO-METABOLIC DISORDERS LATER IN LIFE. RECENT EPIDEMIOLOGIC AND PROSPECTIVE COHORT STUDIES THAT INCLUDE THE MATERNAL AND GESTATIONAL PERIOD HAVE IDENTIFIED MATERNAL AND GESTATIONAL CONDITIONS THAT CONFER INCREASED RISK FOR SUBSEQUENT CARDIO-METABOLIC DISORDERS IN THE ABSENCE OF LOW BIRTH WEIGHT. MATERNAL PRE-CONCEPTION HEALTH STATUS, INCLUDING CHRONIC OBESITY AND TYPE 2 DIABETES, INCREASE RISK FOR CHILDHOOD OBESITY AND OBESITY-RELATED HIGHER BLOOD PRESSURE (BP) IN CHILD OFFSPRING. MATERNAL GESTATIONAL EXPOSURES, INCLUDING GESTATIONAL DIABETES, GESTATIONAL HYPERTENSION, AND PREECLAMPSIA, ARE ASSOCIATED WITH HIGHER BP IN OFFSPRING. OTHER MATERNAL EXPOSURES SUCH AS CIGARETTE SMOKE AND AIR POLLUTION ALSO INCREASE RISK FOR HIGHER BP IN CHILD OFFSPRING. RECENT, BUT LIMITED, DATA INDICATE THAT ASSISTED REPRODUCTIVE TECHNOLOGIES CAN BE ASSOCIATED WITH HYPERTENSION IN CHILDHOOD, DESPITE OTHERWISE NORMAL GESTATION AND HEALTHY NEWBORN. GESTATIONAL EXPOSURES ASSOCIATED WITH HIGHER BP IN CHILDHOOD CAN BE RELATED TO FAMILIAL LIFESTYLE FACTORS, GENETICS, OR EPIGENETIC MODIFICATION OF FETAL DEOXYRIBONUCLEIC ACID (DNA). THESE FACTORS, OR COMBINATION OF FACTORS, AS WELL AS OTHER ADVERSE INTRAUTERINE CONDITIONS, COULD INDUCE FETAL PROGRAMING LEADING TO HEALTH CONSEQUENCES IN LATER LIFE. CURRENT AND DEVELOPING RESEARCH WILL PROVIDE ADDITIONAL INSIGHTS ON GESTATIONAL EXPOSURES AND FETAL ADJUSTMENTS THAT INCREASE RISK FOR HIGHER BP LEVELS IN CHILDHOOD.	2020	
                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                       
14   652  48 BISPHENOL A AS EPIGENETIC MODULATOR: SETTING THE STAGE FOR CARCINOGENESIS? BACKGROUND: BISPHENOL A (BPA) IS ONE OF THE MOST WIDELY PRODUCED CHEMICALS WORLDWIDE AND IS OFTEN USED IN THE PRODUCTION OF FOOD AND BEVERAGE CONTAINERS. AS A RESULT OF BPA CONTACT WITH FOOD, DRINK AND TOILETRIES, ITS INGESTION AND ABSORPTION BY HUMANS HAS BEEN GROWING. THE INDUSTRIALIZATION AND MODERN LIFESTYLES BROUGHT A CONSTANT EXPOSURE TO SEVERAL HEALTH-DISTURBING COMPOUNDS AND USHERED A NEW ERA OF CHRONIC DISEASES. THE ENDOCRINE DISRUPTOR POTENTIAL OF BPA IS WELL KNOWN, BUT THE RESEARCH AROUND ITS EPIGENOTOXIC EFFECTS RAISED FURTHER CONCERNS WHETHER CHRONIC EXPOSURE TO BPA CAN CONTRIBUTE TO CHRONIC HUMAN ILLNESS, INCLUDING CANCER IN HORMONE-SENSITIVE ORGANS. MATERIALS AND METHODS: FOCUSING ON COMPUTERIZED DATABASES, WE REVIEWED ORIGINAL AND REVIEW ARTICLES WHICH ELUCIDATE AND LINK SOME OF THE INFORMATION ALREADY AVAILABLE ABOUT BPA AND RELATED EPIGENETIC ALTERATIONS. RESULTS: A NUMBER OF STUDIES INDICATE THAT SHORT-TERM ADMINISTRATION OF LOW OR HIGH-DOSES OF BPA MAY BE ASSOCIATED WITH AN INCREASED RISK OF EPIGENETIC MODIFICATIONS, INCREASING THE RISK FOR CARCINOGENESIS. HOWEVER, IT IS CLEAR THAT MORE STUDIES CONSIDERING REAL DAILY EXPOSURES ARE ESSENTIAL TO DEFINE A REAL TOLERABLE DAILY INTAKE AND TO TIGHTEN UP MANUFACTORY REGULATIONS. CONCLUSION: IN THIS REVIEW, WE HIGHLIGHT SOME EVIDENCES SUGGESTING A RELATIONSHIP BETWEEN BPA EXPOSURE, GENOTOXIC ACTIVITY AND EPIGENETIC MODIFICATIONS, WHICH MAY PRIME FOR CARCINOGENESIS.	2015	
                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                             
15  5179  36 PREGNANCY: AN UNDERUTILIZED WINDOW OF OPPORTUNITY TO IMPROVE LONG-TERM MATERNAL AND INFANT HEALTH-AN APPEAL FOR CONTINUOUS FAMILY CARE AND INTERDISCIPLINARY COMMUNICATION. PHYSIOLOGIC ADAPTATIONS DURING PREGNANCY UNMASK A WOMAN'S PREDISPOSITION TO DISEASES. COMPLICATIONS ARE INCREASINGLY PREDICTED BY FIRST-TRIMESTER ALGORITHMS, AMPLIFY A PRE-EXISTING MATERNAL PHENOTYPE AND ACCELERATE RISKS FOR CHRONIC DISEASES IN THE OFFSPRING UP TO ADULTHOOD (BARKER HYPOTHESIS). RECENT EVIDENCE SUGGESTS THAT VICE VERSA, PREGNANCY DISEASES ALSO INDICATE MATERNAL AND EVEN GRANDPARENT'S RISKS FOR CHRONIC DISEASES (REVERSE BARKER HYPOTHESIS). PUB-MED AND EMBASE WERE REVIEWED FOR MESH TERMS "FETAL PROGRAMMING" AND "PREGNANCY COMPLICATIONS COMBINED WITH MATERNAL DISEASE" UNTIL JANUARY 2017. STUDIES LINKING PREGNANCY COMPLICATIONS TO FUTURE CARDIOVASCULAR, METABOLIC, AND THROMBOTIC RISKS FOR MOTHER AND OFFSPRING WERE REVIEWED. WOMEN WITH A HISTORY OF MISCARRIAGE, FETAL GROWTH RESTRICTION, PREECLAMPSIA, PRETERM DELIVERY, OBESITY, EXCESSIVE GESTATIONAL WEIGHT GAIN, GESTATIONAL DIABETES, SUBFERTILITY, AND THROMBOPHILIA MORE FREQUENTLY DEMONSTRATE WITH ECHOCARDIOGRAPHIC ABNORMALITIES, HIGHER FASTING INSULIN, DEVIATING LIPIDS OR CLOTTING FACTORS AND SHOW DEFECTIVE ENDOTHELIAL FUNCTION. THROMBOPHILIA HINTS TO THROMBOTIC RISKS IN LATER LIFE. PREGNANCY ABNORMALITIES CORRELATE WITH FUTURE CARDIOVASCULAR AND METABOLIC COMPLICATIONS AND EARLIER MORTALITY. CONVERSELY, WOMEN WITH A NORMAL PREGNANCY HAVE LOWER RATES OF SUBSEQUENT DISEASES THAN THE GENERAL FEMALE POPULATION CREATING THE TERM: "PREGNANCY AS A WINDOW FOR FUTURE HEALTH." ALTHOUGH THE PLACENTA WORKS AS A GATEKEEPER, MANY PREGNANCY COMPLICATIONS MAY LEAD TO SICKNESS AND EARLIER DEATH IN LATER LIFE WHEN THE CHILD BECOMES AN ADULT. THE EPIGENETIC MECHANISMS AND THE MISMATCH BETWEEN PRE- AND POSTNATAL LIFE HAVE CREATED THE TERM "FETAL ORIGIN OF ADULT DISEASE." UP TO NOW, THE IMPACT OF CARDIOVASCULAR, METABOLIC, OR THROMBOTIC RISK PROFILES HAS BEEN INVESTIGATED SEPARATELY FOR MOTHER AND CHILD. IN THIS MANUSCRIPT, WE STRIVE TO ILLUSTRATE THE CONSEQUENCES FOR BOTH, FETUS AND MOTHER WITHIN A COHESIVE PERSPECTIVE AND THUS TRY TO DEMONSTRATE THE COMPLEX INTERRELATIONSHIP OF GENETICS AND EPIGENETICS FOR LONG-TERM HEALTH OF SOCIETIES AND FUTURE GENERATIONS. MATERNAL-FETAL MEDICINE SPECIALISTS SHOULD HAVE A KEY ROLE IN THE PREVENTION OF NON-COMMUNICABLE DISEASES BY IMPLEMENTING A FRAMEWORK FOR PATIENT CONSULTATION AND INTERDISCIPLINARY NETWORKS. HEALTH-CARE PROVIDERS AND POLICY MAKERS SHOULD INCREASINGLY INVEST IN A STRATIFIED PRIMARY PREVENTION AND FOLLOW-UP TO REDUCE THE INCREASING NUMBER OF MANIFEST CARDIOVASCULAR AND METABOLIC DISEASES AND TO PREVENT WASTE OF HEALTH-CARE RESOURCES.	2017	
                                                                                                                                                                                                                                                                                                                       
16   418  45 ANCESTRAL EXPOSURE TO STRESS EPIGENETICALLY PROGRAMS PRETERM BIRTH RISK AND ADVERSE MATERNAL AND NEWBORN OUTCOMES. BACKGROUND: CHRONIC STRESS IS CONSIDERED TO BE ONE OF MANY CAUSES OF HUMAN PRETERM BIRTH (PTB), BUT NO DIRECT EVIDENCE HAS YET BEEN PROVIDED. HERE WE SHOW IN RATS THAT STRESS ACROSS GENERATIONS HAS DOWNSTREAM EFFECTS ON ENDOCRINE, METABOLIC AND BEHAVIOURAL MANIFESTATIONS OF PTB POSSIBLY VIA MICRORNA (MIRNA) REGULATION. METHODS: PREGNANT DAMS OF THE PARENTAL GENERATION WERE EXPOSED TO STRESS FROM GESTATIONAL DAYS 12 TO 18. THEIR PREGNANT DAUGHTERS (F1) AND GRAND-DAUGHTERS (F2) EITHER WERE STRESSED OR REMAINED AS NON-STRESSED CONTROLS. GESTATIONAL LENGTH, MATERNAL GESTATIONAL WEIGHT GAIN, BLOOD GLUCOSE AND PLASMA CORTICOSTERONE LEVELS, LITTER SIZE AND OFFSPRING WEIGHT GAIN FROM POSTNATAL DAYS 1 TO 30 WERE RECORDED IN EACH GENERATION, INCLUDING F3. MATERNAL BEHAVIOURS WERE ANALYSED FOR THE FIRST HOUR AFTER COMPLETED PARTURITION, AND OFFSPRING SENSORIMOTOR DEVELOPMENT WAS RECORDED ON POSTNATAL DAY (P) 7. F0 THROUGH F2 MATERNAL BRAIN FRONTAL CORTEX, UTERUS AND PLACENTA MIRNA AND GENE EXPRESSION PATTERNS WERE USED TO IDENTIFY STRESS-INDUCED EPIGENETIC REGULATORY PATHWAYS OF MATERNAL BEHAVIOUR AND PREGNANCY MAINTENANCE. RESULTS: PROGRESSIVELY UP TO THE F2 GENERATION, STRESS GRADUALLY REDUCED GESTATIONAL LENGTH, MATERNAL WEIGHT GAIN AND BEHAVIOURAL ACTIVITY, AND INCREASED BLOOD GLUCOSE LEVELS. REDUCED OFFSPRING GROWTH AND DELAYED BEHAVIOURAL DEVELOPMENT IN THE STRESS COHORT WAS RECOGNIZABLE AS EARLY AS P7, WITH THE GREATEST EFFECT IN THE F3 OFFSPRING OF TRANSGENERATIONALLY STRESSED MOTHERS. FURTHERMORE, STRESS ALTERED MIRNA EXPRESSION PATTERNS IN THE BRAIN AND UTERUS OF F2 MOTHERS, INCLUDING THE MIR-200 FAMILY, WHICH REGULATES PATHWAYS RELATED TO BRAIN PLASTICITY AND PARTURITION, RESPECTIVELY. MAIN MIR-200 FAMILY TARGET GENES IN THE UTERUS, STAT5B, ZEB1 AND ZEB2, WERE DOWNREGULATED BY MULTIGENERATIONAL STRESS IN THE F1 GENERATION. ZEB2 WAS ALSO REDUCED IN THE STRESSED F2 GENERATION, SUGGESTING A CAUSAL MECHANISM FOR DISTURBED PREGNANCY MAINTENANCE. ADDITIONALLY, STRESS INCREASED PLACENTAL MIR-181A, A MARKER OF HUMAN PTB. CONCLUSIONS: THE FINDINGS INDICATE THAT A FAMILY HISTORY OF STRESS MAY PROGRAM CENTRAL AND PERIPHERAL PATHWAYS REGULATING GESTATIONAL LENGTH AND MATERNAL AND NEWBORN HEALTH OUTCOMES IN THE MATERNAL LINEAGE. THIS NEW PARADIGM MAY MODEL THE ORIGIN OF MANY HUMAN PTB CAUSES.	2014	
                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                               
17  3610  29 IN UTERO EXPOSURE TO ENDOCRINE-DISRUPTING CHEMICALS, MATERNAL FACTORS AND ALTERATIONS IN THE EPIGENETIC LANDSCAPE UNDERLYING LATER-LIFE HEALTH EFFECTS. WIDESPREAD PERSISTENCE OF ENDOCRINE-DISRUPTING CHEMICALS (EDCS) IN THE ENVIRONMENT HAS MANDATED THE NEED TO STUDY THEIR POTENTIAL EFFECTS ON AN INDIVIDUAL'S LONG-TERM HEALTH AFTER BOTH ACUTE AND CHRONIC EXPOSURE PERIODS. IN THIS REVIEW ARTICLE A PARTICULAR FOCUS IS GIVEN ON IN UTERO EXPOSURE TO EDCS IN RODENT MODELS WHICH RESULTED IN ALTERED EPIGENETIC PROGRAMMING AND TRANSGENERATIONAL EFFECTS IN THE OFFSPRING CAUSING DISRUPTED REPRODUCTIVE AND METABOLIC PHENOTYPES. THE LITERATURE TO DATE ESTABLISHES THE IMPACT OF TRANSGENERATIONAL EFFECTS OF EDCS POTENTIALLY ASSOCIATED WITH EPIGENETIC MEDIATED MECHANISMS. THEREFORE, THIS REVIEW AIMS TO PROVIDE A COMPREHENSIVE OVERVIEW OF EPIGENETIC PROGRAMMING AND IT'S REGULATION IN MAMMALS, PRIMARILY FOCUSING ON THE EPIGENETIC PLASTICITY AND SUSCEPTIBILITY TO EXOGENOUS HORMONE ACTIVE CHEMICALS DURING THE EARLY DEVELOPMENTAL PERIOD. FURTHER, WE HAVE ALSO IN DEPTH DISCUSSED THE EPIGENETIC ALTERATIONS ASSOCIATED WITH THE EXPOSURE TO SELECTED EDCS SUCH AS BISPHENOL A (BPA), DI-2-ETHYLHEXYL PHTHALATE (DEHP) AND VINCLOZLIN UPON IN UTERO EXPOSURE ESPECIALLY IN RODENT MODELS.	2022	
                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                          
18  5107  32 POLYCYSTIC OVARY SYNDROME: A BRAIN DISORDER CHARACTERIZED BY EATING PROBLEMS ORIGINATING DURING PUBERTY AND ADOLESCENCE. POLYCYSTIC OVARY SYNDROME (PCOS) IS AN ENDOCRINE CONDITION ASSOCIATED WITH REPRODUCTIVE AND PSYCHIATRIC DISORDERS, AND WITH OBESITY. EATING DISORDERS, SUCH AS BULIMIA AND RECURRENT DIETING, ARE ALSO LINKED TO PCOS. THEY CAN LEAD TO THE EPIGENETIC DYSREGULATION OF THE HYPOTHALAMIC-PITUITARY-GONADAL (HPG) AXIS, THEREBY IMPACTING ON OVARIAN FOLLICULOGENESIS. WE POSTULATE THAT PCOS IS INDUCED BY PSYCHOLOGICAL DISTRESS AND EPISODES OF OVEREATING AND/OR DIETING DURING PUBERTY AND ADOLESCENCE, WHEN BODY DISSATISFACTION AND EMOTIONAL DISTRESS ARE OFTEN PRESENT. WE PROPOSE THAT UPREGULATED ACTIVATION OF THE CENTRAL HPG AXIS DURING THIS PERIOD CAN BE EPIGENETICALLY ALTERED BY PSYCHOLOGICAL STRESSORS AND BY BULIMIA/RECURRENT DIETING, WHICH ARE COMMON DURING ADOLESCENCE AND WHICH CAN LEAD TO PCOS. THIS HYPOTHESIS IS BASED ON EVENTS THAT OCCUR DURING A LARGELY NEGLECTED STAGE OF FEMALE REPRODUCTIVE DEVELOPMENT. TO DATE, MOST RESEARCH INTO THE ORIGINS OF PCOS HAS FOCUSED ON THE PRENATAL INDUCTION OF THIS DISORDER, PARTICULARLY IN UTERO ANDROGENIZATION AND THE ROLE OF ANTI-MULLERIAN HORMONE. ESTABLISHING CAUSALITY IN OUR PERIPUBERTAL MODEL REQUIRES PROSPECTIVE COHORT STUDIES FROM INFANCY. MECHANISTIC STUDIES SHOULD CONSIDER THE ROLE OF THE GUT MICROBIOTA IN ADDITION TO THE EPIGENETIC REGULATION OF (NEURO) HORMONES.

PURPOSE: BISPHENOL A (BPA) IS AN ENVIRONMENTAL TOXIN, CLEARLY CAPABLE OF INITIATING EPIGENETIC MODIFICATIONS, LEADING TO THE DEVELOPMENT OF NUMEROUS HUMAN ILLNESSES SUCH AS METABOLIC, REPRODUCTIVE, AND BEHAVIOURAL ABNORMALITIES. IT ALSO CAUSES OXIDATIVE STRESS, WHICH HAS BEEN SHOWN TO BE ALLEVIATED BY SELENIUM SUPPLEMENTATION. THE PURPOSE OF THIS STUDY WAS TO DETERMINE THE EFFECT OF TRAINING OF BPA EXPOSURE DURING PREGNANCY ON URINE BPA LEVELS. METHODS: THIS RESEARCH ENROLLED 30 PREGNANT WOMEN WHO WERE IN THEIR FIRST TRIMESTER AND WERE FREE OF CHRONIC ILLNESS. WOMEN WERE ASKED QUESTIONS ON THEIR SOCIODEMOGRAPHIC FEATURES, ANTHROPOMETRIC MEASURES, OBSTETRIC CHARACTERISTICS, BPA AWARENESS LEVEL, BPA EXPOSURE AND THE HEALTH PRACTICES IN PREGNANCY SCALE AS A PRE-TEST AND POST-TEST. THE INITIAL URINE SAMPLES WERE TAKEN FROM WOMEN IN THEIR FIRST TRIMESTER AND STORED IN BPA-FREE BAGS. THEN, TRAINING WAS DELIVERED TO ENCOURAGE BPA EXPOSURE REDUCTION AND MATERNAL HEALTH AWARENESS. FIRST-TRIMESTER FACE-TO-FACE INSTRUCTION AND BROCHURE DISTRIBUTION WERE FOLLOWED BY REFRESHER, REMINDER, AND FOLLOW-UP TRAININGS DURING THE SECOND AND THIRD TRIMESTERS. URINE SAMPLES FROM WOMEN IN THEIR SECOND AND THIRD TRIMESTERS WERE OBTAINED AGAIN. THE LEVELS OF BPA IN URINE WERE MEASURED USING THE LIQUID CHROMATOGRAPHY-MASS SPECTROMETRY ON 90 SAMPLES. EACH PERSON'S URINE CONCENTRATION DIFFERS, THUS THE CREATININE LEVEL IN ALL SAMPLES WAS ALSO CALCULATED AND COMPARED TO THE BPA CONTENT, AND THE RESULTS WERE EVALUATED. RESULTS: OUR STUDY SHOWN THAT BPA EXPOSURE MAY BE LOWERED BY TRAINING. IT HAS BEEN DEMONSTRATED THAT REDUCING BPA EXPOSURE AND INCREASING KNOWLEDGE CAN RESULT IN AN IMPROVEMENT IN HEALTH STATUS. ADDITIONALLY, IT HAS BEEN DEMONSTRATED THAT TRAININGS GREATLY MINIMIZE EXPOSURE-CAUSING BEHAVIOURS. CONCLUSION: IT WAS DISCOVERED THAT WHILE THE DURATION OF A SINGLE TRAINING DOES NOT MAKE A MEANINGFUL EFFECT, THE CONTINUING OF REMINDER TRAININGS DID MAKE A SUBSTANTIAL DIFFERENCE IN THE URINE BPA LEVEL.	2022	
                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                          
20  1767  33 EARLY-LIFE EXPOSURE TO ENDOCRINE DISRUPTING CHEMICALS AND LATER-LIFE HEALTH OUTCOMES: AN EPIGENETIC BRIDGE? A GROWING BODY OF EVIDENCE DEMONSTRATES THAT ADVERSE EVENTS EARLY IN DEVELOPMENT, AND PARTICULARLY DURING INTRAUTERINE LIFE, MAY PROGRAM RISKS FOR DISEASES IN ADULT LIFE. INCREASING EVIDENCE HAS BEEN ACCUMULATED INDICATING THE IMPORTANT ROLE OF EPIGENETIC REGULATION INCLUDING DNA METHYLATION, HISTONE MODIFICATIONS AND MIRNAS IN DEVELOPMENTAL PROGRAMMING. AMONG THE ENVIRONMENTAL FACTORS WHICH PLAY AN IMPORTANT ROLE IN PROGRAMMING OF CHRONIC PATHOLOGIES, THE ENDOCRINE-DISRUPTING CHEMICALS (EDCS) THAT HAVE ESTROGENIC, ANTI-ESTROGENIC, AND ANTI-ANDROGENIC ACTIVITY ARE OF SPECIFIC CONCERN BECAUSE THE DEVELOPING ORGANISM IS EXTREMELY SENSITIVE TO PERTURBATION BY SUBSTANCES WITH HORMONE-LIKE ACTIVITY. AMONG EDCS, THERE ARE MANY SUBSTANCES THAT ARE CONSTANTLY PRESENT IN THE MODERN HUMAN ENVIRONMENT OR ARE IN WIDESPREAD USE, INCLUDING DIOXIN AND DIOXIN-LIKE COMPOUNDS, PHTHALATES, AGRICULTURAL PESTICIDES, POLYCHLORINATED BIPHENYLS, INDUSTRIAL SOLVENTS, PHARMACEUTICALS, AND HEAVY METALS. APART FROM THEIR COMMON ENDOCRINE ACTIVE PROPERTIES, SEVERAL EDCS HAVE BEEN SHOWN TO DISRUPT DEVELOPMENTAL EPIGENOMIC PROGRAMMING. THE PURPOSE OF THIS REVIEW IS TO PROVIDE A SUMMARY OF RECENT RESEARCH FINDINGS WHICH INDICATE THAT EXPOSURE TO EDCS DURING IN-UTERO AND/OR NEONATAL DEVELOPMENT CAN CAUSE LONG-TERM HEALTH OUTCOMES VIA MECHANISMS OF EPIGENETIC MEMORY.	2014
