1  5294 126 PROTECTIVE EFFECTS OF MATERNAL METHYL DONOR SUPPLEMENTATION ON ADULT OFFSPRING OF HIGH FAT DIET-FED DAMS. OBESITY HAS BECOME A GLOBAL PUBLIC HEALTH PROBLEM ASSOCIATED WITH METABOLIC DYSFUNCTION AND CHRONIC DISORDERS. IT HAS BEEN SHOWN THAT THE RISK OF OBESITY AND THE DNA METHYLATION PROFILES OF THE OFFSPRING CAN BE AFFECTED BY MATERNAL NUTRITION, SUCH AS HIGH-FAT DIET (HFD) CONSUMPTION. THE AIM OF THIS STUDY WAS TO INVESTIGATE WHETHER METABOLIC DYSREGULATION AND PHYSIOLOGICAL ABNORMALITIES IN OFFSPRING CAUSED BY MATERNAL HFD CAN BE ALLEVIATED BY THE TREATMENT OF METHYL DONORS DURING PREGNANCY AND LACTATION OF DAMS. FEMALE C57BL/6 MICE WERE ASSIGNED TO SPECIFIC GROUPS AND GIVEN DIFFERENT NUTRIENTS (CONTROL DIET, CONTROL+MET, HFD AND HFD+MET) THROUGHOUT GESTATION AND LACTATION. OFFSPRING OF EACH GROUP WERE WEANED ONTO A CONTROL DIET AT 3 WEEKS OF AGE. PHYSIOLOGICAL (WEIGHT GAIN AND ADIPOSE COMPOSITION) AND METABOLIC (PLASMA BIOCHEMICAL ANALYSES) OUTCOMES WERE ASSESSED IN MALE AND FEMALE ADULT OFFSPRING. EXPRESSION AND DNA METHYLATION PROFILES OF OBESOGENIC-RELATED GENES INCLUDING PPAR GAMMA, FATTY ACID SYNTHASE, LEPTIN AND ADIPONECTIN WERE ALSO DETECTED IN VISCERAL FAT OF OFFSPRING. THE RESULTS SHOWED THAT DIETARY SUPPLEMENTATION WITH METHYL DONORS CAN PREVENT THE ADVERSE EFFECTS OF MATERNAL HFD ON OFFSPRING. CHANGES IN THE EXPRESSION AND DNA METHYLATION OF OBESOGENIC-RELATED GENES INDICATED THAT EPIGENETIC REGULATION MAY CONTRIBUTE TO THE EFFECTS OF MATERNAL DIETARY FACTORS ON OFFSPRING OUTCOMES.	2016	
                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                    
2  4752  51 NOVEL ROLE OF GESTATIONAL HYDRALAZINE IN LIMITING MATERNAL AND DIETARY OBESITY-RELATED CHRONIC KIDNEY DISEASE. BACKGROUND: MATERNAL OBESITY IS A RISK FACTOR FOR CHRONIC KIDNEY DISEASE (CKD) IN OFFSPRING, UNDERPINNING THE THEORY OF THE DEVELOPMENTAL ORIGINS OF HEALTH AND DISEASE. DNA METHYLATION HAS BEEN IMPLICATED IN THE PROGRAMMING OF ADULT CHRONIC DISEASE BY MATERNAL OBESITY, THEREFORE, DNA DEMETHYLATING AGENTS MAY MITIGATE OFFSPRING RISK OF DISEASE. IN RODENT MODELS, LOW-DOSE HYDRALAZINE HAS PREVIOUSLY BEEN SHOWN TO REDUCE RENAL FIBROSIS VIA DNA DEMETHYLATION. WE USED MOUSE MODELS OF MATERNAL OBESITY AND OFFSPRING OBESITY TO DETERMINE WHETHER ADMINISTRATION OF LOW-DOSE HYDRALAZINE DURING GESTATION CAN PREVENT FETAL PROGRAMMING OF CKD IN OFFSPRING. METHODS: FEMALE C57BL/6 MICE RECEIVED HIGH FAT DIET (HFD) OR CHOW PRIOR TO MATING, DURING GESTATION AND LACTATION. DURING GESTATION, DAMS RECEIVED SUBCUTANEOUS HYDRALAZINE (5 MG/KG) OR SALINE THRICE-WEEKLY. MALE OFFSPRING WEANED TO HFD OR CHOW, WHICH CONTINUED UNTIL ENDPOINT AT 32 WEEKS. BIOMETRIC AND METABOLIC PARAMETERS, RENAL GLOBAL DNA METHYLATION, RENAL FUNCTIONAL AND STRUCTURAL CHANGES, AND RENAL MARKERS OF FIBROSIS, INFLAMMATION AND OXIDATIVE STRESS WERE ASSESSED AT ENDPOINT. RESULTS: OFFSPRING EXPOSED TO MATERNAL OBESITY OR DIET-INDUCED OBESITY HAD SIGNIFICANTLY INCREASED RENAL GLOBAL DNA METHYLATION, TOGETHER WITH OTHER ADVERSE RENAL EFFECTS INCLUDING ALBUMINURIA, GLOMERULOSCLEROSIS, RENAL FIBROSIS, AND OXIDATIVE STRESS. OFFSPRING EXPOSED TO GESTATIONAL HYDRALAZINE HAD SIGNIFICANTLY REDUCED RENAL GLOBAL DNA METHYLATION. IN OBESE OFFSPRING OF OBESE MOTHERS, GESTATIONAL HYDRALAZINE SIGNIFICANTLY DECREASED ALBUMINURIA, GLOMERULOSCLEROSIS, AND SERUM CREATININE. OBESE OFFSPRING OF HYDRALAZINE-TREATED LEAN MOTHERS DISPLAYED REDUCED MARKERS OF RENAL FIBROSIS AND OXIDATIVE STRESS. CONCLUSION: GESTATIONAL HYDRALAZINE DECREASED RENAL GLOBAL DNA METHYLATION AND EXERTED RENOPROTECTIVE EFFECTS IN OFFSPRING. THIS SUPPORTS A POTENTIAL THERAPEUTIC EFFECT OF HYDRALAZINE IN PREVENTING MATERNAL OBESITY OR DIETARY OBESITY-RELATED CKD, THROUGH AN EPIGENETIC MECHANISM.	2021	
                                                                                                                                                                                                                                                                                                         
3  6724  31 VITAMIN D: EFFECTS ON PREGNANCY, MATERNAL, FETAL AND POSTNATAL OUTCOMES. A HIGH PREVALENCE OF VITAMIN D DEFICIENCY AND ITS NEGATIVE CONSEQUENCES FOR HEALTH IS IDENTIFIED AS AREA OF PRIMARY CONCERN FOR SCIENTISTS AND CLINICIANS WORLDWIDE. VITAMIN D DEFICIENCY AFFECTS NOT ONLY BONE HEALTH BUT MANY SOCIALLY SIGNIFICANT ACUTE AND CHRONIC DISEASES. OBSERVATIONAL STUDIES SUPPORT THAT PREGNANT AND LACTATING WOMEN, CHILDREN AND TEENAGERS REPRESENT THE HIGH RISK GROUPS FOR DEVELOPING VITAMIN D DEFICIENCY. CURRENT EVIDENCE HIGHLIGHTS A CRUCIAL ROLE OF VITAMIN D IN PROVIDING THE FETAL LIFE-SUPPORT SYSTEM AND FETUS DEVELOPMENT, INCLUDING IMPLANTATION, PLACENTAL FORMATION, INTRA- AND POSTPARTUM PERIODS. HYPOVITAMINOSIS D DURING PREGNANCY IS ASSOCIATED WITH A HIGHER INCIDENCE OF PLACENTAL INSUFFICIENCY, SPONTANEOUS ABORTIONS AND PRETERM BIRTH, PREECLAMPSIA, GESTATIONAL DIABETES, IMPAIRED FETAL AND CHILDHOOD GROWTH, INCREASED RISK OF AUTOIMMUNE DISEASES FOR OFFSPRINGS. POTENTIAL MECHANISMS FOR THE OBSERVED ASSOCIATIONS CONTAIN METABOLIC, IMMUNOMODULATORY AND ANTIINFLAMMATORY EFFECTS OF VITAMIN D. EPIGENETIC MODIFICATIONS IN VITAMIN D-ASSOCIATED GENES AND FETAL PROGRAMMING ARE OF PARTICULAR INTEREST. THE CONCEPT OF PREVENTING VITAMIN D DEFICIENCY IS ACTIVELY DISCUSSED, INCLUDING SUPPLEMENTATION IN DIFFERENT ETHNIC GROUPS, REQUIRED DOSES, TIME OF INITIATION AND THERAPY DURATION, INFLUENCE ON GESTATION AND CHILDBIRTH. AN ADEQUATE SUPPLY OF VITAMIN D DURING PREGNANCY IMPROVES THE MATERNAL AND FETAL OUTCOMES, SHORT AND LONG TERM HEALTH OF THE OFFSPRING. STILL CURRENT DATA ON RELATIONSHIP BETWEEN MATERNAL VITAMIN D STATUS AND PREGNANCY OUTCOMES REMAINS CONTROVERSIAL. THE LARGE OBSERVATIONAL AND INTERVENTIONAL RANDOMIZED CONTROL TRIALS ARE REQUIRED TO CREATE EVIDENCE-BASED GUIDELINES FOR THE SUPPLEMENTATION OF VITAMIN D IN PREGNANT AND LACTATING WOMEN.	2018	
                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                              
4  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	
                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                         
5  5178  31 PREGNANCY AS A FUNDAMENTAL DETERMINANT OF CHILD HEALTH: A REVIEW. PURPOSE OF REVIEW: MATERNAL CONDITIONS AND EXPOSURES DURING PREGNANCY INCLUDING OVER- AND UNDERNUTRITION ARE ASSOCIATED WITH POOR CHILDBIRTH OUTCOMES, GROWTH, DEVELOPMENT AND CHRONIC CHILDHOOD DISEASES. WE EXAMINED CONTEMPORARY PREGNANCY-RELATED DETERMINANTS OF CHILD HEALTH. RECENT FINDINGS: WHILE MATERNAL UNDERNUTRITION REMAINS A MAJOR CONTRIBUTOR TO LOW BIRTH WEIGHT, MATERNAL OBESITY AFFECTS FOETAL GROWTH, BIRTH WEIGHT, SURVIVAL AND IS ASSOCIATED WITH CHILDHOOD OBESITY, ASTHMA AND AUTISTIC SPECTRUM DISORDERS. EMERGING EVIDENCE SUGGESTS THAT EPIGENETIC CHANGES, THE PRENATAL MICROBIOME AND MATERNAL IMMUNE ACTIVATION (MIA), A NEUROINFLAMMATORY PROCESS INDUCED BY DIET AND OTHER EXPOSURES CAUSE FOETAL PROGRAMMING RESULTING IN THESE CHRONIC CHILDHOOD DISEASES. MATERNAL DIET IS POTENTIALLY A MODIFIABLE RISK FACTOR FOR CONTROLLING LOW BIRTH WEIGHT, OBESITY AND CHRONIC DISEASE IN CHILDHOOD. FURTHER STUDIES ARE WARRANTED TO REFINE GUIDANCE ON DIETARY RESTRICTION AND PHYSICAL ACTIVITY DURING PREGNANCY AND DETERMINE HOW MIA AND PRENATAL MICROBIOTA CAN BE APPLIED TO CONTROL CHILDHOOD DISEASES ARISING FROM PROGRAMMING.	2022	
                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                              
6  4066  37 MATERNAL AND PATERNAL PERICONCEPTIONAL NUTRITION AS AN INDICATOR OF OFFSPRING METABOLIC SYNDROME RISK IN LATER LIFE THROUGH EPIGENETIC IMPRINTING: A SYSTEMATIC REVIEW. AIMS: THIS REVIEW EXAMINED WHETHER MATERNAL AND PATERNAL PERICONCEPTIONAL NUTRITION EFFECTS AN OFFSPRING'S LIKELIHOOD OF DEVELOPING CHRONIC METABOLIC RELATED CONDITIONS DUE TO EPIGENETIC IMPRINTING. METHODS: A LITERATURE SEARCH WAS CONDUCTED IN MULTIPLE SCIENCE DATABASES AND LIMITED TO STUDIES PUBLISHED AFTER 2012, IN ENGLISH LANGUAGE AND PEER REVIEWED. THE DATA FROM SELECTED ARTICLES WERE EXTRACTED AND A QUALITATIVE APPROACH WAS EMPLOYED DUE TO HETEROGENEITY OF RESULTS. RESULTS: NEWBORNS FROM OBESE FATHERS SHOWED ALTERED METHYLATION OVERALL AND SIGNIFICANT HYPOMETHYLATION AT THE INSULIN-LIKE GROWTH FACTOR 2 (IGF2) GENE. HIGH MATERNAL PRE-PREGNANCY BODY MASS INDEX (BMI) WAS ASSOCIATED WITH ALTERED OFFSPRING DNA METHYLATION LEVELS AND GESTATIONAL DIABETES MELLITUS INDUCED SIGNIFICANTLY INCREASED METHYLATION LEVELS IN OFFSPRING. GESTATIONAL WEIGHT GAIN WAS NOT ASSOCIATED WITH DIFFERENTIALLY METHYLATED CORD BLOOD. BIRTH WEIGHT WAS HIGHER IN OFFSPRING EXPOSED TO FAMINE IN EARLY GESTATION. OFFSPRING BORN POST MATERNAL BARIATRIC SURGERY SHOWED A LOWER PERCENTAGE OF BODY FAT AND IMPROVED FASTING INSULIN LEVELS COMPARED TO SIBLINGS BORN PRE-MATERNAL BARIATRIC SURGERY. CONCLUSIONS: THE AVAILABLE EVIDENCE SUGGESTS THAT POOR MATERNAL AND PATERNAL PERICONCEPTIONAL NUTRITION CAN INCREASE THE RISK OF METABOLIC SYNDROME IN OFFSPRING, THROUGH EPIGENETIC IMPRINTING. POTENTIAL PARENTS SHOULD BE ADVISED THAT MAINTAINING A HEALTHY DIET AND BMI IS LIKELY TO REDUCE THE RISK OF METABOLIC SYNDROME IN OFFSPRING.	2017	
                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                    
7    73  36 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	
                                                                                                                                                                                                                                                                                                                                                                                                                                                                                        
8  3595  25 IMPLICATIONS OF MATERNAL CONDITIONS AND PREGNANCY COURSE ON OFFSPRING'S MEDICAL PROBLEMS IN ADULT LIFE. IN THE LAST DECADE, NUMEROUS EPIDEMIOLOGICAL, CLINICAL AND EXPERIMENTAL DATA SHOW THAT PERICONCEPTIONAL, PERINATAL AND POSTNATAL ENVIRONMENT DETERMINES THE OFFSPRING'S RISK FOR LATER-LIFE CHRONIC DISEASE. FOR THIS PHENOMENON, THE TERM "FETAL" OR "PERINATAL PROGRAMMING" IS USED. IN EXPOSED OFFSPRING ALREADY IN CHILDHOOD AND EARLY ADULTHOOD, METABOLIC AND CARDIOVASCULAR CHANGES CAN BE OBSERVED, LEADING TO OBESITY, DIABETES AND HYPERTENSION. NOWADAYS, THE MODE OF CONCEPTION (E.G., IN VITRO FERTILIZATION), MATERNAL METABOLIC CONDITIONS (E.G., UNDERNUTRITION, OVERNUTRITION, DIABETES) AND COMPLICATIONS DURING PREGNANCY (E.G., PREECLAMPSIA, INTRAUTERINE GROWTH RESTRICTION) ARE SUSPECTED TO BE NEGATIVE PREDICTORS FOR OFFSPRING'S LONG-TERM HEALTH. MECHANISMS RESPONSIBLE FOR THESE EFFECTS STILL REMAIN MAINLY UNCLEAR, BUT INCLUDE EPIGENETIC, TRANSCRIPTIONAL, ENDOPLASMIC RETICULUM STRESS, AND REACTIVE OXYGEN SPECIES. THIS REVIEW PRESENTS A PIECE OF THE PUZZLE WITH REGARDS TO PERICONCEPTIONAL AND EARLY PERINATAL CONDITIONS DETERMINING LATER-LIFE RISK FOR CHRONIC ADULT DISEASE.	2016	
                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                    
9  3578  26 IMPACT OF PARENTAL OVER- AND UNDERWEIGHT ON THE HEALTH OF OFFSPRING. PARENTAL EXCESS WEIGHT AND ESPECIALLY PREGESTATIONAL MATERNAL OBESITY AND EXCESSIVE WEIGHT GAIN DURING PREGNANCY HAVE BEEN RELATED TO AN INCREASED RISK OF METABOLIC (OBESITY, TYPE 2 DIABETES, CARDIOVASCULAR DISEASE, METABOLIC SYNDROME) AND NONMETABOLIC (CANCER, OSTEOPOROSIS, ASTHMA, NEUROLOGIC ALTERATIONS) DISEASES IN THE OFFSPRING, PROBABLY MEDIATED BY EPIGENETIC MECHANISMS OF FETAL PROGRAMMING. MATERNAL UNDERWEIGHT IS LESS COMMON IN DEVELOPED SOCIETIES, BUT THE DISCREPANCY BETWEEN A POOR NUTRITIONAL ENVIRONMENT IN UTERO AND A NORMAL OR EXCESSIVE POSTNATAL FOOD SUPPLY WITH RAPID GROWTH CATCH-UP APPEARS TO BE THE MAIN CANDIDATE MECHANISM OF THE DEVELOPMENT OF CHRONIC DISEASES DURING THE OFFSPRING'S ADULTHOOD. THE ROLE OF THE POSTNATAL ENVIRONMENT IN BOTH SCENARIOS (PARENTAL OVERWEIGHT OR UNDERWEIGHT) ALSO SEEMS TO INFLUENCE THE OFFSPRING'S HEALTH. LIFESTYLE INTERVENTIONS BEFORE AND DURING PREGNANCY IN BOTH PARENTS, BUT ESPECIALLY IN THE MOTHER, AS WELL AS IN CHILDREN AFTER BIRTH, ARE ADVISABLE TO COUNTERACT THE MANY UNDESIRABLE CHRONIC CONDITIONS DESCRIBED.	2019	
                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                              
10  4079  45 MATERNAL L-CARNITINE SUPPLEMENTATION AMELIORATES RENAL UNDERDEVELOPMENT AND EPIGENETIC CHANGES IN MALE MICE OFFSPRING DUE TO MATERNAL SMOKING. OBJECTIVES: EPIDEMIOLOGICAL AND ANIMAL STUDIES SHOWED THAT L-CARNITINE (LC) SUPPLEMENTATION CAN AMELIORATE OXIDATIVE STRESS-INDUCED TISSUES DAMAGE. WE HAVE PREVIOUSLY SHOWN THAT MATERNAL CIGARETTE SMOKE EXPOSURE (SE) CAN INCREASE RENAL OXIDATIVE STRESS IN NEWBORN OFFSPRING WITH POSTNATAL KIDNEY UNDERDEVELOPMENT AND RENAL DYSFUNCTION IN ADULTHOOD, WHICH WERE NORMALISED BY LC ADMINISTRATION IN THE SE DAMS DURING PREGNANCY. EXPOSURE TO AN ADVERSE INTRAUTERINE ENVIRONMENT MAY LEAD TO ALTERATION IN THE EPIGENOME, A MECHANISM BY WHICH ADVERSE PRENATAL CONDITIONS INCREASE THE SUSCEPTIBILITY TO CHRONIC DISEASE LATER IN LIFE. THE CURRENT STUDY AIMED TO DETERMINE WHETHER MATERNAL SE INDUCES EPIGENETIC CHANGES IN THE OFFSPRING'S KIDNEY ARE ASSOCIATED WITH RENAL UNDERDEVELOPMENT, AND THE PROTECTIVE EFFECT OF MATERNAL LC SUPPLEMENTATION. METHOD: FEMALE BALB/C MICE (7 WEEKS) WERE EXPOSED TO CIGARETTE SMOKE (SE) OR AIR (SHAM) FOR 6 WEEKS PRIOR TO MATING, DURING GESTATION AND LACTATION. A SUBGROUP OF THE SE DAMS RECEIVED LC VIA DRINKING WATER (SE + LC, 1.5 MMOL/L) THROUGHOUT GESTATION AND LACTATION. MALE OFFSPRING WERE STUDIED AT POSTNATAL DAY (P)1, P20, AND 13 WEEKS. RESULTS: MATERNAL SE ALTERED THE EXPRESSION OF RENAL DEVELOPMENT MARKERS GLIAL CELL LINE-DERIVED NEUROTROPHIC FACTOR AND FIBROBLAST GROWTH FACTOR 2, WHICH WERE ASSOCIATED WITH INCREASED RENAL GLOBAL DNA METHYLATION AND DNA METHYLTRANSFERASE 1 MRNA EXPRESSION AT BIRTH. THESE DISORDERS WERE REVERSED BY MATERNAL LC ADMINISTRATION. CONCLUSION: THE EFFECT OF MATERNAL SE ON RENAL UNDERDEVELOPMENT INVOLVES GLOBAL EPIGENETIC ALTERATIONS FROM BIRTH, WHICH CAN BE PREVENTED BY MATERNAL LC SUPPLEMENTATION.	2019	
                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                              
11  4504  29 MOTHER'S PRE-PREGNANCY BMI AND PLACENTAL CANDIDATE MIRNAS: FINDINGS FROM THE ENVIRONAGE BIRTH COHORT. THERE IS INCREASING EVIDENCE THAT THE PREDISPOSITION FOR DEVELOPMENT OF CHRONIC DISEASES ARISES AT THE EARLIEST TIMES OF LIFE. IN THIS CONTEXT, MATERNAL PRE-PREGNANCY WEIGHT MIGHT MODIFY FETAL METABOLISM AND THE CHILD'S PREDISPOSITION TO DEVELOP DISEASE LATER IN LIFE. THE AIM OF THIS STUDY IS TO INVESTIGATE THE ASSOCIATION BETWEEN MATERNAL PRE-PREGNANCY BODY MASS INDEX (BMI) AND MIRNA ALTERATIONS IN PLACENTAL TISSUE AT BIRTH. IN 211 MOTHER-NEWBORN PAIRS FROM THE ENVIRONAGE BIRTH COHORT, WE ASSESSED PLACENTAL EXPRESSION OF SEVEN MIRNAS IMPORTANT IN CRUCIAL CELLULAR PROCESSES IMPLICATED IN ADIPOGENESIS AND/OR OBESITY. MULTIPLE LINEAR REGRESSION MODELS WERE USED TO ADDRESS THE ASSOCIATIONS BETWEEN PRE-PREGNANCY BMI AND PLACENTAL CANDIDATE MIRNA EXPRESSION. MATERNAL PRE-PREGNANCY BMI AVERAGED (+/-SD) 23.9 (+/-4.1) KG/M(2). IN NEWBORN GIRLS (NOT IN BOYS) PLACENTAL MIR-20A, MIR-34A AND MIR-222 EXPRESSION WAS LOWER WITH HIGHER MATERNAL PRE-PREGNANCY BMI. IN ADDITION, THE ASSOCIATION BETWEEN MATERNAL PRE-PREGNANCY BMI AND PLACENTAL EXPRESSION OF THESE MIRNAS IN GIRLS WAS MODIFIED BY GESTATIONAL WEIGHT GAIN. THE LOWER EXPRESSION OF THESE MIRNAS IN PLACENTA IN ASSOCIATION WITH PRE-PREGNANCY BMI, WAS ONLY EVIDENT IN MOTHERS WITH LOW WEIGHT GAIN (<14 KG). THE PLACENTAL EXPRESSION OF MIR-20A, MIR-34A, MIR-146A, MIR-210 AND MIR-222 MAY PROVIDE A SEX-SPECIFIC BASIS FOR EPIGENETIC EFFECTS OF PRE-PREGNANCY BMI.	2017	
                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                    
12  4086  36 MATERNAL OBESITY DISRUPTS THE METHIONINE CYCLE IN BABOON PREGNANCY. MATERNAL INTAKE OF DIETARY METHYL-MICRONUTRIENTS (E.G. FOLATE, CHOLINE, BETAINE AND VITAMIN B-12) DURING PREGNANCY IS ESSENTIAL FOR NORMAL MATERNAL AND FETAL METHIONINE METABOLISM, AND IS CRITICAL FOR IMPORTANT METABOLIC PROCESSES INCLUDING THOSE INVOLVED IN DEVELOPMENTAL PROGRAMMING. MATERNAL OBESITY AND NUTRIENT EXCESS DURING PREGNANCY INFLUENCE DEVELOPMENTAL PROGRAMMING POTENTIALLY PREDISPOSING ADULT OFFSPRING TO A VARIETY OF CHRONIC HEALTH PROBLEMS. IN THE PRESENT STUDY, WE HYPOTHESIZED THAT MATERNAL OBESITY WOULD DYSREGULATE THE MATERNAL AND FETAL METHIONINE CYCLE. TO TEST THIS HYPOTHESIS, WE DEVELOPED A NULLIPAROUS BABOON OBESITY MODEL FED A HIGH FAT, HIGH ENERGY DIET (HF-HED) PRIOR TO AND DURING GESTATION, AND EXAMINED METHIONINE CYCLE BIOMARKERS (E.G., CIRCULATING CONCENTRATIONS OF HOMOCYSTEINE, METHIONINE, CHOLINE, BETAINE, KEY AMINO ACIDS, FOLATE, AND VITAMIN B-12). ANIMALS WERE GROUP HOUSED ALLOWING FULL PHYSICAL ACTIVITY AND SOCIAL INTERACTION. MATERNAL PREPREGNANCY PERCENT BODY FAT WAS 5% IN CONTROLS AND 19% IN HF-HED MOTHERS, WHILE FETAL WEIGHT WAS 16% LOWER IN OFFSPRING OF HF-HED MOTHERS AT TERM. MATERNAL AND FETAL HOMOCYSTEINE WERE HIGHER, WHILE MATERNAL AND FETAL VITAMIN B-12 AND BETAINE WERE LOWER IN THE HF-HED GROUP. ELEVATIONS IN CIRCULATING MATERNAL FOLATE WERE EVIDENT IN THE HF-HED GROUP INDICATING IMPAIRED FOLATE METABOLISM (METHYL-TRAP) AS A CONSEQUENCE OF MATERNAL VITAMIN B-12 DEPLETION. FINALLY, FETAL METHIONINE, GLYCINE, SERINE, AND TAURINE WERE LOWER IN THE HF-HED FETUSES. THESE DATA SHOW THAT MATERNAL OBESITY DISTURBS THE METHIONINE CYCLE IN PRIMATE PREGNANCY, PROVIDING A MECHANISM FOR THE EPIGENETIC CHANGES OBSERVED AMONG OBESE PREGNANT WOMEN AND SUGGESTING DIAGNOSTIC AND THERAPEUTIC OPPORTUNITIES IN HUMAN PREGNANCIES COMPLICATED BY OBESITY.	2015	
                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                      
13  2077  37 EPIGENETIC DISRUPTION OF PLACENTAL GENES BY CHRONIC MATERNAL CAFETERIA DIET IN RATS. MATERNAL DIET HAS IMPACT ON REPRODUCTION, FETAL DEVELOPMENT AND OFFSPRING BEHAVIOR, ALTHOUGH MOLECULAR MECHANISMS REMAINED UNKNOWN. OUR AIMS WERE TO ASSESS (1) THE EFFECTS OF A CAFETERIA (CAF) DIET (WESTERN DIET HABITS) ON FEMALE REPRODUCTIVE PERFORMANCE, FETAL AND PLACENTAL PARAMETERS ON GESTATIONAL DAY 21 AND LITTER SIZE AND PUP WEIGHT AT BIRTH; AND (2) PLACENTAL MESSENGER RNA (MRNA) EXPRESSION AND EPIGENETIC REGULATION OF INSULIN-LIKE GROWTH FACTOR (IGF) AND VASCULAR ENDOTHELIAL GROWTH FACTOR (VEGF) AND THEIR RECEPTORS. FEMALE WISTAR RATS WERE FED WITH CONTROL OR CAF DIET FROM WEANING UNTIL PARTURITION. AT WEEK 14 AFTER DIETS STARTED, FEMALES WERE MATED AND HALF OF THE ANIMALS WERE EUTHANIZED ON GESTATIONAL DAY 21 TO EVALUATE REPRODUCTIVE PARAMETERS INCLUDING THE PREGNANCY RATE, NUMBER OF CORPORA LUTEA, IMPLANTATION SITES AND RESORPTION SITES. MOREOVER, FETAL WEIGHT AND LENGTH, PLACENTAL WEIGHT, AND PLACENTAL INDEX WERE RECORDED. PLACENTAS WERE COLLECTED FOR MRNA QUANTIFICATION AND DNA METHYLATION ANALYSIS. THE REMAINING ANIMALS WERE ALLOWED TO GIVE BIRTH AND THE NUMBER AND WEIGHT OF THE PUPS WERE EVALUATED. CAF DIET DID NOT AFFECT REPRODUCTIVE PERFORMANCE OR FETAL WEIGHT AND LENGTH. HOWEVER, CAF-FED ANIMALS SHOWED A DECREASE IN PLACENTAL WEIGHT AND INDEX AND THE PUPS EXHIBITED A LOW BIRTH WEIGHT. ADDITIONALLY, WE FOUND AN UPREGULATION OF IGF2 AND A DOWN REGULATION OF VEGF PLACENTAL MRNA EXPRESSION IN CAF DAMS, ASSOCIATED WITH METHYLATION STATUS CHANGES OF THEIR PROMOTERS. WE CONCLUDE THAT FEMALE CHRONIC CAF DIET CONSUMPTION IMPAIRS FETO-PLACENTAL DEVELOPMENT AND COULD BE EXPLAINED BY AN EPIGENETIC DISRUPTION OF IGF AND VEGF SYSTEMS.	2022	
                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                              
14  4886  33 OVERWEIGHT AND OBESITY BEFORE, DURING AND AFTER PREGNANCY: PART 1: PATHOPHYSIOLOGY, MOLECULAR BIOLOGY AND EPIGENETIC CONSEQUENCES. OVERWEIGHT AND OBESITY BEFORE CONCEPTION AS WELL AS EXCESSIVE WEIGHT GAIN DURING PREGNANCY ARE ASSOCIATED WITH ENDOCRINOLOGICAL CHANGES OF MOTHER AND FETUS. INSULIN RESISTANCE PHYSIOLOGICALLY INCREASES DURING PREGNANCY, ADDITIONAL OBESITY FURTHER INCREASES INSULIN RESISTANCE. IN COMBINATION WITH REDUCED INSULIN SECRETION THIS LEADS TO GESTATIONAL DIABETES WHICH MAY DEVELOP INTO TYPE-2-DIABETES. THE ADIPOSE TISSUE PRODUCES TNF-ALPHA, INTERLEUKINS AND LEPTIN AND UPREGULATES THESE ADIPOKINES. INSULIN RESISTANCE AND OBESITY INDUCE INFLAMMATORY PROCESSES AND VASCULAR DYSFUNCTION, WHICH EXPLAINS THE INCREASED RATE OF PREGNANCY-RELATED HYPERTENSION AND PRE-ECLAMPSIA IN OBESE PREGNANT WOMEN. BETWEEN 14 AND 28 GESTATIONAL WEEKS, THE FETAL ADIPOSE TISSUE IS GENERATED AND THE NUMBER OF FAT LOBULES IS DETERMINED. THEREAFTER, AN INCREASE IN ADIPOSE TISSUE IS ARRANGED BY AN ENLARGEMENT OF THE LOBULES (HYPERTROPHY), OR EVEN AN INCREASE IN THE NUMBER OF FAT CELLS (HYPERPLASIA). HUMAN AND ANIMAL STUDIES HAVE SHOWN THAT MATERNAL OBESITY "PROGRAMMES" THE OFFSPRING FOR FURTHER OBESITY AND CHRONIC DISEASE. PREGNANT WOMEN, MIDWIVES, PHYSICIANS AND HEALTH CARE POLITICIANS SHOULD BE BETTER INFORMED ABOUT PREVENTION, PATHOPHYSIOLOGICAL MECHANISMS, AND THE BURDEN FOR SOCIETY CAUSED BY OBESITY BEFORE, DURING AND AFTER PREGNANCY.	2014	
                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                     
15  4069  40 MATERNAL CHRONIC FOLATE SUPPLEMENTATION AMELIORATES BEHAVIOR DISORDERS INDUCED BY PRENATAL HIGH-FAT DIET THROUGH METHYLATION ALTERATION OF BDNF AND GRIN2B IN OFFSPRING HIPPOCAMPUS. SCOPE: MATERNAL CONSUMPTION OF A HIGH-FAT DIET (HFD) DURING PREGNANCY INCREASES THE RISK OF BEHAVIORAL PROBLEMS. FOLATE PLAYS AN IMPORTANT ROLE IN NEUROPLASTICITY AND THE PRESERVATION OF NEURONAL INTEGRITY. THIS STUDY AIMS AT DETERMINING THE INFLUENCE OF DIETS SUPPLEMENTED WITH FOLATE ON OFFSPRING BEHAVIOR, AND THE MECHANISMS INVOLVED. METHODS AND RESULTS: FEMALE MICE WERE FED A CONTROL DIET, AN HFD, CONTROL DIET SUPPLEMENTED WITH FOLATE, OR AN HFD SUPPLEMENTED WITH FOLATE FOR 5 WEEKS BEFORE MATING. OPEN FIELD TASK AND ELEVATED PLUS MAZE ARE USED TO EVALUATE THE OFFSPRING BEHAVIORS. RESULTS SHOWED THAT OFFSPRING COGNITIVE PERFORMANCE AND ANXIETY-RELATED BEHAVIORS, INCLUDING THOSE RELATED TO OPEN FIELD EXPLORATION AND ELEVATED PLUS MAZE, WERE SIGNIFICANTLY IMPROVED WHEN DAMS WERE TREATED WITH FOLATE IN PREGNANCY. MOREOVER, THE MATERNAL FOLATE SUPPLEMENT DECREASED BDNF AND GRIN2B METHYLATION AND UPREGULATED THEIR EXPRESSIONS IN THE BRAIN OF OFFSPRING, WHICH WERE ASSOCIATED WITH DECREASING THE EXPRESSION OF DNA METHYLTRANSFERASES COMPARED WITH THOSE DAMS WERE TREATED ONLY HFD IN PREGNANCY. CONCLUSION: MATERNAL FOLATE SUPPLEMENTATION AMELIORATES BEHAVIOR DISORDERS INDUCED BY PRENATAL HIGH-FAT DIET. THE BENEFICIAL EFFECTS WERE ASSOCIATED WITH METHYLATION AND EXPRESSION ALTERATION OF BDNF AND GRIN2B GENES.	2017	
                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                     
16  1098  32 COLLATERAL DAMAGE: MATERNAL OBESITY DURING PREGNANCY CONTINUES TO RISE. IMPORTANCE: THE PANDEMIC OF OBESITY DURING PREGNANCY NOW AFFLICTS 1 OUT OF EVERY 2 PREGNANT WOMEN IN THE UNITED STATES. EVEN THOUGH UNINTENDED PREGNANCY HAS DECREASED TO 45% OF ALL PREGNANCIES, 50% OF THOSE UNINTENDED PREGNANCIES OCCUR IN OBESE WOMEN. OBJECTIVE: THIS STUDY AIMS TO IDENTIFY WHY CURRENT LIFESTYLE INTERVENTIONS FOR OBESE PREGNANCY ARE NOT EFFECTIVE AND WHAT THE NEWER COMPLICATIONS ARE FOR OBESITY DURING PREGNANCY. EVIDENCE ACQUISITION: AVAILABLE LITERATURES ON CURRENT TREATMENTS FOR MATERNAL OBESITY WERE REVIEWED FOR EFFECTIVENESS. EMERGING MATERNAL AND INFANT COMPLICATIONS FROM OBESITY DURING PREGNANCY WERE EXAMINED FOR SIGNIFICANCE. RESULTS: LIMITATIONS IN SUCCESSFUL INTERVENTIONS FELL INTO 3 BASIC CATEGORIES TO INCLUDE THE FOLLOWING: (1) PRECONCEPTION WEIGHT LOSS; (2) BARIATRIC SURGERY BEFORE PREGNANCY; AND (3) PREVENTION OF EXCESSIVE GESTATIONAL WEIGHT GAIN DURING PREGNANCY. EMERGING SIGNIFICANT PHYSIOLOGICAL CHANGES FROM MATERNAL OBESITY IS COMPOSED OF INFLAMMATION (PLACENTA AND HUMAN MILK), METABOLISM (HORMONES, MICROBIOME, FATTY ACIDS), AND OFFSPRING OUTCOMES (BODY COMPOSITION, CONGENITAL MALFORMATIONS, CHRONIC KIDNEY DISEASE, ASTHMA, NEURODEVELOPMENT, AND BEHAVIOR). CONCLUSIONS AND RELEVANCE: ARE CURRENT PREPREGNANCY LIFESTYLE AND BEHAVIORAL INTERVENTIONS FEASIBLE TO PREVENT MATERNAL OBESITY COMPLICATIONS? EPIGENETIC AND METABOLOMIC RESEARCH WILL BE CRITICAL TO DETERMINE WHAT IS NEEDED TO BLUNT THE EFFECTS OF MATERNAL OBESITY AND TO DISCOVER SUCCESSFUL TREATMENT.	2020	
                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                      
17  2806  33 FETAL PROGRAMMING AND THE RISK OF NONCOMMUNICABLE DISEASE. THE "DEVELOPMENTAL ORIGINS OF HEALTH AND DISEASE" (DOHAD) HYPOTHESIS PROPOSES THAT ENVIRONMENTAL CONDITIONS DURING FETAL AND EARLY POST-NATAL DEVELOPMENT INFLUENCE LIFELONG HEALTH AND CAPACITY THROUGH PERMANENT EFFECTS ON GROWTH, STRUCTURE AND METABOLISM. THIS HAS BEEN CALLED 'PROGRAMMING'. THE HYPOTHESIS IS SUPPORTED BY EPIDEMIOLOGICAL EVIDENCE IN HUMANS LINKING NEWBORN SIZE, AND INFANT GROWTH AND NUTRITION, TO ADULT HEALTH OUTCOMES, AND BY EXPERIMENTS IN ANIMALS SHOWING THAT MATERNAL UNDER- AND OVER-NUTRITION AND OTHER INTERVENTIONS (E.G., GLUCOCORTICOID EXPOSURE) DURING PREGNANCY LEAD TO ABNORMAL METABOLISM AND BODY COMPOSITION IN THE ADULT OFFSPRING. EARLY LIFE PROGRAMMING IS NOW THOUGHT TO BE IMPORTANT IN THE ETIOLOGY OF OBESITY, TYPE 2 DIABETES, AND CARDIOVASCULAR DISEASE, OPENING UP THE POSSIBILITY THAT THESE COMMON DISEASES COULD BE PREVENTED BY ACHIEVING OPTIMAL FETAL AND INFANT DEVELOPMENT. THIS IS LIKELY TO HAVE ADDITIONAL BENEFITS FOR INFANT SURVIVAL AND HUMAN CAPITAL (E.G., IMPROVED COGNITIVE PERFORMANCE AND PHYSICAL WORK CAPACITY). FETAL NUTRITION IS INFLUENCED BY THE MOTHER'S DIET AND BODY SIZE AND COMPOSITION, BUT HARD EVIDENCE THAT THE NUTRITION OF THE HUMAN MOTHER PROGRAMMES CHRONIC DISEASE RISK IN HER OFFSPRING IS CURRENTLY LIMITED. RECENT FINDINGS FROM FOLLOW-UP OF CHILDREN BORN AFTER RANDOMISED NUTRITIONAL INTERVENTIONS IN PREGNANCY ARE MIXED, BUT SHOW SOME EVIDENCE OF BENEFICIAL EFFECTS ON VASCULAR FUNCTION, LIPID CONCENTRATIONS, GLUCOSE TOLERANCE AND INSULIN RESISTANCE. WORK IN EXPERIMENTAL ANIMALS SUGGESTS THAT EPIGENETIC PHENOMENA, WHEREBY GENE EXPRESSION IS MODIFIED BY DNA METHYLATION, AND WHICH ARE SENSITIVE TO THE NUTRITIONAL ENVIRONMENT IN EARLY LIFE, MAY BE ONE MECHANISM UNDERLYING PROGRAMMING.	2013	
                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                               
18  4202  26 METABOLIC SYNDROME IN CHILDREN BORN SMALL-FOR-GESTATIONAL AGE. BEING BORN SMALL-FOR-GESTATIONAL AGE AND A RAPID INCREASE IN WEIGHT DURING EARLY CHILDHOOD AND INFANCY HAS BEEN STRONGLY LINKED WITH CHRONIC DISEASES, INCLUDING METABOLIC SYNDROME, WHICH HAS BEEN RELATED TO INTRAUTERINE LIFE ENVIRONMENT AND LINKED TO EPIGENETIC FETAL PROGRAMMING. METABOLIC SYNDROME INCLUDES WAIST CIRCUMFERENCE >/= 90(TH) PERCENTILE FOR AGE, SEX AND RACE, HIGHER LEVELS OF BLOOD PRESSURE, TRIGLYCERIDES AND FASTING GLUCOSE, AND LOW LEVELS OF HDL-CHOLESTEROL. INSULIN RESISTANCE MAY BE PRESENT AS EARLY AS 1 YEAR OF AGE, AND OBESITY AND/OR TYPE 2 DIABETES ARE MORE PREVALENT IN THOSE BORN SGA THAN THOSE BORN AGA. THE PROGRAMMING OF ADAPTIVE RESPONSES IN CHILDREN BORN SGA INCLUDES AN ASSOCIATION WITH INCREASED BLOOD PRESSURE, CHANGES IN ENDOTHELIAL FUNCTION, ARTERIAL PROPERTIES AND CORONARY DISEASE. EARLY INTERVENTIONS SHOULD BE DIRECTED TO APPROPRIATE MATERNAL NUTRITION, BEFORE AND DURING PREGNANCY, PROMOTION OF BREAST FEEDING, AND PREVENTION OF RAPID WEIGHT GAIN DURING INFANCY, AND TO PROMOTE A HEALTHY LIFESTYLE.	2011	
                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                     
19  2801  30 FEMALE OBESITY: SHORT- AND LONG-TERM CONSEQUENCES ON THE OFFSPRING. THE WORLDWIDE PREVALENCE OF OBESITY HAS RISEN OVER THE PAST FEW DECADES AND WOMEN ARE CURRENTLY MORE LIKELY THAN EVER TO ENTER PREGNANCY OBESE. PRE-PREGNANCY OBESITY AND EXCESSIVE GESTATIONAL WEIGHT GAIN INCREASE MISCARRIAGE RATES AND OBSTETRIC AND NEONATAL COMPLICATIONS, WHICH RESULT IN A LOWER HEALTHY LIVE BIRTH RATE. IN ADDITION TO ITS NEGATIVE CONSEQUENCES FOR THE MOTHER, OBESITY HAS BEEN SHOWN TO BE AN IMPORTANT RISK FACTOR FOR CHRONIC ILLNESSES, SUCH AS CARDIOVASCULAR DISEASE, METABOLIC SYNDROME AND TYPE 2 DIABETES IN THE ADOLESCENCE AND ADULTHOOD OF THE OFFSPRING. MOREOVER, MATERNAL OBESITY CAUSES PSYCHOLOGICAL PROBLEMS, PHYSICAL DISABILITIES AND HIGHER HEALTHCARE COSTS. FETAL PROGRAMMING OF METABOLIC FUNCTION INDUCED BY OBESITY, THROUGH PHYSIOLOGICAL AND/OR EPIGENETIC MECHANISMS, MAY HAVE AN INTERGENERATIONAL EFFECT AND COULD, THUS, PERPETUATE OBESITY IN THE NEXT GENERATION. IN ORDER TO BREAK THIS VICIOUS CIRCLE AND AVOID SERIOUS SHORT- AND LONG-TERM NEGATIVE OUTCOMES FOR BOTH MOTHERS AND FETUSES, THE PREVENTION AND ADEQUATE MANAGEMENT OF OBESITY AND GESTATIONAL WEIGHT GAIN ARE ESSENTIAL.	2013	
                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                      
20   418  42 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
