1  6713 184 VISCERAL ADIPOSITY SYNDROME. THE ASSOCIATION OF ANTHROPOMETRIC (WAIST CIRCUMFERENCE) AND HEMODYNAMIC (BLOOD PRESSURE) CHANGES WITH ABNORMALITIES IN GLUCOSE AND LIPID METABOLISM HAS BEEN MOTIVATION FOR A LOT OF DISCUSSIONS IN THE LAST 30 YEARS. NOWADAYS, BLOOD PRESSURE, BODY MASS INDEX/ABDOMINAL CIRCUMFERENCE, GLYCEMIA, TRIGLYCERIDEMIA, AND HDL-CHOLESTEROL CONCENTRATIONS ARE CONSIDERED IN THE DEFINITION OF METABOLIC SYNDROME, REFERRED AS VISCERAL ADIPOSITY SYNDROME (VAS) IN THE PRESENT REVIEW. HOWEVER, MORE THAN 250 YEARS AGO AN ASSOCIATION BETWEEN VISCERAL AND MEDIASTINAL OBESITY WITH HYPERTENSION, GOUT, AND OBSTRUCTIVE APNEA HAD ALREADY BEEN RECOGNIZED. EXPANSION OF VISCERAL ADIPOSE TISSUE SECONDARY TO CHRONIC OVER-CONSUMPTION OF CALORIES STIMULATES THE RECRUITMENT OF MACROPHAGES, WHICH ASSUME AN INFLAMMATORY PHENOTYPE AND PRODUCE CYTOKINES THAT DIRECTLY INTERFERE WITH INSULIN SIGNALING, RESULTING IN INSULIN RESISTANCE. IN TURN, INSULIN RESISTANCE (IR) MANIFESTS ITSELF IN VARIOUS TISSUES, CONTRIBUTING TO THE OVERALL PHENOTYPE OF VAS. FOR EXAMPLE, IN WHITE ADIPOSE TISSUE, IR RESULTS IN LIPOLYSIS, INCREASED FREE FATTY ACIDS RELEASE AND WORSENING OF INFLAMMATION, SINCE FATTY ACIDS CAN BIND TO TOLL-LIKE RECEPTORS. IN THE LIVER, IR RESULTS IN INCREASED HEPATIC GLUCOSE PRODUCTION, CONTRIBUTING TO HYPERGLYCEMIA; IN THE VASCULAR ENDOTHELIUM AND KIDNEY, IR RESULTS IN VASOCONSTRICTION, SODIUM RETENTION AND, CONSEQUENTLY, ARTERIAL HYPERTENSION. OTHER PLAYERS HAVE BEEN RECOGNIZED IN THE DEVELOPMENT OF VAS, SUCH AS GENETIC PREDISPOSITION, EPIGENETIC FACTORS ASSOCIATED WITH EXPOSURE TO AN UNFAVOURABLE INTRAUTERINE ENVIRONMENT AND THE GUT MICROBIOTA. MORE RECENTLY, EXPERIMENTAL AND CLINICAL STUDIES HAVE SHOWN THE AUTONOMIC NERVOUS SYSTEM PARTICIPATES IN MODULATING VISCERAL ADIPOSE TISSUE. THE SYMPATHETIC NERVOUS SYSTEM IS RELATED TO ADIPOSE TISSUE FUNCTION AND DIFFERENTIATION THROUGH BETA1, BETA2, BETA3, ALPHA1, AND ALPHA2 ADRENERGIC RECEPTORS. THE RELATION IS BIDIRECTIONAL: SYMPATHETIC DENERVATION OF ADIPOSE TISSUE BLOCKS LIPOLYSIS TO A VARIETY OF LIPOLYTIC STIMULI AND ADIPOSE TISSUE SEND INPUTS TO THE BRAIN. AN IMBALANCE OF SYMPATHETIC/PARASYMPATHETIC AND ALPHA2 ADRENERGIC/BETA3 RECEPTOR IS RELATED TO VISCERAL ADIPOSE TISSUE STORAGE AND INSULIN SENSITIVITY. THUS, IN ADDITION TO THE WELL-KNOWN FACTORS CLASSICALLY ASSOCIATED WITH VAS, ABNORMAL AUTONOMIC ACTIVITY ALSO EMERGES AS AN IMPORTANT FACTOR REGULATING WHITE ADIPOSE TISSUE, WHICH HIGHLIGHTS COMPLEX ROLE OF ADIPOSE TISSUE IN THE VAS.	2016	
                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                
2  6742  45 WHITHER THE ETIOPATHOGENESIS (AND SCOLIOGENY) OF ADOLESCENT IDIOPATHIC SCOLIOSIS? ALTHOUGH CONSIDERABLE PROGRESS HAD BEEN MADE IN THE PAST TWO DECADES IN UNDERSTANDING THE ETIOPATHOGENESIS OF ADOLESCENT IDIOPATHIC SCOLIOSIS (AIS), IT STILL LACKS AN AGREED THEORY OF ETIOPATHOGENESIS. ONE PROBLEM MAY BE THAT AIS RESULTS NOT FROM ONE CAUSE, BUT SEVERAL THAT INTERACT WITH VARIOUS GENETIC PREDISPOSING FACTORS. THERE IS A VIEW THERE ARE TWO OTHER PATHOGENIC PROCESSES FOR IDIOPATHIC SCOLIOSIS NAMELY, INITIATING (OR INDUCING), AND THOSE THAT CAUSE CURVE PROGRESSION. TWIN STUDIES AND OBSERVATIONS OF FAMILY AGGREGATION HAVE REVEALED SIGNIFICANT GENETIC CONTRIBUTIONS TO IDIOPATHIC SCOLIOSIS, THAT PLACE AIS AMONG OTHER COMMON DISEASE OR COMPLEX TRAITS WITH A HIGH HERITABILITY INTERPRETED BY THE GENETIC VARIANT HYPOTHESIS OF DISEASE. WE SUMMARIZE ETIOPATHOGENETIC KNOWLEDGE OF AIS AS THEORIES OF PATHOGENESIS INCLUDING RECENT MULTIPLE CONCEPTS, AND BLOOD TESTS FOR AIS BASED ON PREDICTIVE BIOMARKERS AND GENETIC VARIANTS THAT SIGNIFY DISEASE RISK. THERE IS INCREASING EVIDENCE FOR THE POSSIBILITY OF AN UNDERLYING NEUROLOGICAL DISORDER FOR AIS, RESEARCH WHICH HOLDS PROMISE. LIKE BRAIN RESEARCH, MOST AIS WORKERS FOCUS ON THEIR OWN CORNER AND THERE IS A NEED FOR GREATER INTEGRATION OF RESEARCH EFFORT. EPIGENETICS, A RELATIVELY RECENT FIELD, EVALUATES FACTORS CONCERNED WITH GENE EXPRESSION IN RELATION TO ENVIRONMENT, DISEASE, NORMAL DEVELOPMENT AND AGING, WITH A COMPLEX REGULATION ACROSS THE GENOME DURING THE FIRST DECADE OF LIFE. RESEARCH ON THE ROLE OF ENVIRONMENTAL FACTORS, EPIGENETICS AND CHRONIC NON-COMMUNICABLE DISEASES (NCDS) INCLUDING ADIPOSITY, AFTER A SLOW START, HAS EXPLODED IN THE LAST DECADE. NOT SO FOR AIS RESEARCH AND THE ENVIRONMENT WHERE, EXCEPT FOR MONOZYGOTIC TWIN STUDIES, THERE ARE ONLY SPORADIC REPORTS TO SUGGEST THAT ENVIRONMENTAL FACTORS ARE AT WORK IN ETIOLOGY. HERE, WE EXAMINE EPIGENETIC CONCEPTS AS THEY MAY RELATE TO HUMAN DEVELOPMENT, NORMAL LIFE HISTORY PHASES AND AIS PATHOGENESIS. ALTHOUGH AIS IS NOT REGARDED AS AN NCD, LIKE THEM, IT IS ASSOCIATED WITH WHOLE ORGANISM METABOLIC PHENOMENA, INCLUDING LOWER BODY MASS INDEX, LOWER CIRCULATING LEPTIN LEVELS AND OTHER SYSTEMIC DISORDERS. SOME EPIGENETIC RESEARCH APPLIED TO SILVER-RUSSELL SYNDROME AND ADIPOSITY IS EXAMINED, FROM WHICH SUGGESTIONS ARE MADE FOR CONSIDERATION OF AIS EPIGENETIC RESEARCH, CROSS-SECTIONAL AND LONGITUDINAL. THE WORD SCOLIOGENY IS SUGGESTED TO INCLUDE ETIOLOGY, PATHOGENESIS AND PATHOMECHANISM.	2012	
                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                       
3  4202  41 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	
                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                         
4  2699  39 EXCESS BODY WEIGHT: NOVEL INSIGHTS INTO ITS ROLES IN OBESITY COMORBIDITIES. EXCESS BODY WEIGHT IS A GLOBAL HEALTH PROBLEM DUE TO SEDENTARY LIFESTYLE AND UNHEALTHY DIET, AFFECTING 2 BILLION POPULATION WORLDWIDE. OBESITY IS A MAJOR RISK FACTOR FOR METABOLIC DISEASES. NOTABLY, THE METABOLIC RISK OF OBESITY LARGELY DEPENDS ON BODY WEIGHT DISTRIBUTION, OF WHICH VISCERAL ADIPOSE TISSUES BUT NOT SUBCUTANEOUS FATS ARE CLOSELY ASSOCIATED WITH OBESITY COMORBIDITIES, INCLUDING TYPE 2 DIABETES, NON-ALCOHOLIC FATTY LIVER DISEASE, CARDIOVASCULAR DISEASE AND CERTAIN TYPES OF CANCER. LATEST MULTI-OMICS AND MECHANISTICAL STUDIES REPORTED THE CRUCIAL INVOLVEMENT OF GENETIC AND EPIGENETIC ALTERATIONS, ADIPOKINES DYSREGULATION, IMMUNITY CHANGES, IMBALANCE OF WHITE AND BROWN ADIPOSE TISSUES, AND GUT MICROBIAL DYSBIOSIS IN MEDIATING THE PATHOGENIC ASSOCIATION BETWEEN VISCERAL ADIPOSE TISSUES AND COMORBIDITIES. IN THIS REVIEW, WE EXPLORE THE EPIDEMIOLOGY OF EXCESS BODY WEIGHT AND THE UP-TO-DATE MECHANISM OF HOW EXCESS BODY WEIGHT AND OBESITY LEAD TO CHRONIC COMPLICATIONS. WE ALSO EXAMINE THE UTILIZATION OF VISCERAL FAT MEASUREMENT AS AN ACCURATE CLINICAL PARAMETER FOR RISK ASSESSMENT IN HEALTHY INDIVIDUALS AND CLINICAL OUTCOME PREDICTION IN OBESE SUBJECTS. IN ADDITION, CURRENT APPROACHES FOR THE PREVENTION AND TREATMENT OF EXCESS BODY WEIGHT AND ITS RELATED METABOLIC COMORBIDITIES ARE FURTHER DISCUSSED.	2023	
                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                            
5   701  34 BROWN FAT DNMT3B DEFICIENCY AMELIORATES OBESITY IN FEMALE MICE. OBESITY RESULTS FROM A CHRONIC ENERGY IMBALANCE DUE TO ENERGY INTAKE EXCEEDING ENERGY EXPENDITURE. ACTIVATION OF BROWN FAT THERMOGENESIS HAS BEEN SHOWN TO COMBAT OBESITY. EPIGENETIC REGULATION, INCLUDING DNA METHYLATION, HAS EMERGED AS A KEY REGULATOR OF BROWN FAT THERMOGENIC FUNCTION. HERE WE AIMED TO STUDY THE ROLE OF DNMT3B, A DNA METHYLTRANSFERASE INVOLVED IN DE NOVO DNA METHYLATION, IN THE REGULATION OF BROWN FAT THERMOGENESIS AND OBESITY. WE FOUND THAT THE SPECIFIC DELETION OF DNMT3B IN BROWN FAT PROMOTES THE THERMOGENIC AND MITOCHONDRIAL PROGRAM IN BROWN FAT, ENHANCES ENERGY EXPENDITURE, AND DECREASES ADIPOSITY IN FEMALE MICE FED A REGULAR CHOW DIET. WITH A LEAN PHENOTYPE, THE FEMALE KNOCKOUT MICE ALSO EXHIBIT INCREASED INSULIN SENSITIVITY. IN ADDITION, DNMT3B DEFICIENCY IN BROWN FAT ALSO PREVENTS DIET-INDUCED OBESITY AND INSULIN RESISTANCE IN FEMALE MICE. INTERESTINGLY, OUR RNA-SEQ ANALYSIS REVEALED AN UPREGULATION OF THE PI3K-AKT PATHWAY IN THE BROWN FAT OF FEMALE DNMT3B KNOCKOUT MICE. HOWEVER, MALE DNMT3B KNOCKOUT MICE HAVE NO CHANGE IN THEIR BODY WEIGHT, SUGGESTING THE EXISTENCE OF SEXUAL DIMORPHISM IN THE BROWN FAT DNMT3B KNOCKOUT MODEL. OUR DATA DEMONSTRATE THAT DNMT3B PLAYS AN IMPORTANT ROLE IN THE REGULATION OF BROWN FAT FUNCTION, ENERGY METABOLISM AND OBESITY IN FEMALE MICE.	2021	
                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                        
6  4066  31 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  6743  45 WHITHER THE ETIOPATHOGENESIS (AND SCOLIOGENY) OF ADOLESCENT IDIOPATHIC SCOLIOSIS? INCORPORATING PRESENTATIONS ON SCOLIOGENY AT THE 2012 IRSSD AND SRS MEETINGS. THIS PAPER AIMS TO INTEGRATE INTO CURRENT UNDERSTANDING OF AIS CAUSATION, ETIOPATHOGENETIC INFORMATION PRESENTED AT TWO MEETINGS DURING 2012 NAMELY, THE INTERNATIONAL RESEARCH SOCIETY OF SPINAL DEFORMITIES (IRSSD) AND THE SCOLIOSIS RESEARCH SOCIETY (SRS). THE ULTIMATE HOPE IS TO PREVENT THE OCCURRENCE OR PROGRESSION OF THE SPINAL DEFORMITY OF AIS WITH NON-INVASIVE TREATMENT, POSSIBLY MEDICAL. THIS MIGHT BE ATTAINED BY PERSONALISED POLYMECHANISTIC PREVENTIVE THERAPY TARGETING THE APPROPRIATE ETIOLOGY AND/OR ETIOPATHOGENETIC PATHWAYS, TO AVOID FUSION AND MAINTAIN SPINAL MOBILITY. ALTHOUGH CONSIDERABLE PROGRESS HAD BEEN MADE IN THE PAST TWO DECADES IN UNDERSTANDING THE ETIOPATHOGENESIS OF ADOLESCENT IDIOPATHIC SCOLIOSIS (AIS), IT STILL LACKS AN AGREED THEORY OF ETIOPATHOGENESIS. ONE PROBLEM MAY BE THAT AIS RESULTS NOT FROM ONE CAUSE, BUT SEVERAL THAT INTERACT WITH VARIOUS GENETIC PREDISPOSING FACTORS. THERE IS A VIEW THERE ARE TWO OTHER PATHOGENIC PROCESSES FOR IDIOPATHIC SCOLIOSIS NAMELY, INITIATING (OR INDUCING), AND THOSE THAT CAUSE CURVE PROGRESSION. TWIN STUDIES AND OBSERVATIONS OF FAMILY AGGREGATION HAVE REVEALED SIGNIFICANT GENETIC CONTRIBUTIONS TO IDIOPATHIC SCOLIOSIS, THAT PLACE AIS AMONG OTHER COMMON DISEASE OR COMPLEX TRAITS WITH A HIGH HERITABILITY INTERPRETED BY THE GENETIC VARIANT HYPOTHESIS OF DISEASE. WE SUMMARIZE ETIOPATHOGENETIC KNOWLEDGE OF AIS AS THEORIES OF PATHOGENESIS INCLUDING RECENT MULTIPLE CONCEPTS, AND BLOOD TESTS FOR AIS BASED ON PREDICTIVE BIOMARKERS AND GENETIC VARIANTS THAT SIGNIFY DISEASE RISK. THERE IS INCREASING EVIDENCE FOR THE POSSIBILITY OF AN UNDERLYING NEUROLOGICAL DISORDER FOR AIS, RESEARCH WHICH HOLDS PROMISE. LIKE BRAIN RESEARCH, MOST AIS WORKERS FOCUS ON THEIR OWN CORNER AND THERE IS A NEED FOR GREATER INTEGRATION OF RESEARCH EFFORT. EPIGENETICS, A RELATIVELY RECENT FIELD, EVALUATES FACTORS CONCERNED WITH GENE EXPRESSION IN RELATION TO ENVIRONMENT, DISEASE, NORMAL DEVELOPMENT AND AGING, WITH A COMPLEX REGULATION ACROSS THE GENOME DURING THE FIRST DECADE OF LIFE. RESEARCH ON THE ROLE OF ENVIRONMENTAL FACTORS, EPIGENETICS AND CHRONIC NON-COMMUNICABLE DISEASES (NCDS) INCLUDING ADIPOSITY, AFTER A SLOW START, HAS EXPLODED IN THE LAST DECADE. NOT SO FOR AIS RESEARCH AND THE ENVIRONMENT WHERE, EXCEPT FOR MONOZYGOTIC TWIN STUDIES, THERE ARE ONLY SPORADIC REPORTS TO SUGGEST THAT ENVIRONMENTAL FACTORS ARE AT WORK IN ETIOLOGY. HERE, WE EXAMINE EPIGENETIC CONCEPTS AS THEY MAY RELATE TO HUMAN DEVELOPMENT, NORMAL LIFE HISTORY PHASES AND AIS PATHOGENESIS. ALTHOUGH AIS IS NOT REGARDED AS AN NCD, LIKE THEM, IT IS ASSOCIATED WITH WHOLE ORGANISM METABOLIC PHENOMENA, INCLUDING LOWER BODY MASS INDEX, LOWER CIRCULATING LEPTIN LEVELS AND OTHER SYSTEMIC DISORDERS. SOME EPIGENETIC RESEARCH APPLIED TO SILVER-RUSSELL SYNDROME AND ADIPOSITY IS EXAMINED, FROM WHICH SUGGESTIONS ARE MADE FOR CONSIDERATION OF AIS EPIGENETIC RESEARCH, CROSS-SECTIONAL AND LONGITUDINAL. THE WORD SCOLIOGENY IS SUGGESTED TO INCLUDE ETIOLOGY, PATHOGENESIS AND PATHOMECHANISM.	2013	

8  6545  32 TRANSCRIPTOMIC AND EPIGENETIC CHANGES IN THE HYPOTHALAMUS ARE INVOLVED IN AN INCREASED SUSCEPTIBILITY TO A HIGH-FAT-SUCROSE DIET IN PRENATALLY STRESSED FEMALE RATS. DISTURBANCES IN THE PRENATAL PERIOD ARE LINKED TO METABOLIC DISORDERS IN ADULTHOOD, IMPLYING THE HYPOTHALAMIC SYSTEMS OF APPETITE AND ENERGY BALANCE REGULATION. IN ORDER TO ANALYZE THE CENTRAL EFFECTS OF A HIGH-FAT-SUCROSE (HFS) DIET IN PRENATALLY STRESSED (PNS) FEMALE ADULT RATS, WISTAR DAMS WERE EXPOSED TO CHRONIC-MILD-STRESS DURING THE THIRD WEEK OF GESTATION AND WERE THEN COMPARED WITH UNSTRESSED CONTROLS. ADULT FEMALE OFFSPRING WERE FED A CHOW OR HFS DIET FOR 10 WEEKS. CHANGES IN BODY WEIGHT, ADIPOSITY AS WELL AS EXPRESSION AND METHYLATION LEVELS OF SELECTED HYPOTHALAMIC GENES WERE ANALYZED. PNS INDUCED LOWER BIRTHWEIGHT AND BODY LENGTH WITH NO CHANGES IN BODY FAT MASS. AFTER THE HFS DIET, THE EXPECTED OVERWEIGHT MODEL WAS OBSERVED ACCOMPANIED BY HIGHER ADIPOSITY AND INSULIN RESISTANCE, WHICH WAS WORSENED BY PNS. THE STRESS MODEL INDUCED HIGHER ENERGY INTAKE IN ADULTHOOD. HYPOTHALAMIC GENE EXPRESSION ANALYSIS REVEALED THAT THE HFS DIET DECREASED SLC6A3 (DOPAMINE ACTIVE TRANSPORTER), NPY (NEUROPEPTIDE Y) AND IR (INSULIN RECEPTOR) AND INCREASED POMC (PRO-OPIOMELANOCORTIN). HYPOTHALAMIC DNA METHYLATION LEVELS IN THE PROMOTER REGION OF SLC6A3 REVEALED THAT SLC6A3 WAS HYPERMETHYLATED BY THE HFS DIET IN CPG SITE -53 BP TO THE TRANSCRIPTION START SITE. HFS DIET ALSO HYPERMETHYLATED CPG SITE -167 BP OF THE POMC PROMOTER ONLY IN NONSTRESSED ANIMALS. NO CORRELATIONS WERE FOUND BETWEEN GENE EXPRESSION AND DNA METHYLATION LEVELS. THESE RESULTS IMPLY THAT EARLY-LIFE STRESS IN FEMALES INCREASED PREDISPOSITION TO DIET-INDUCED OBESITY IN ADULTHOOD.	2012	
                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                       
9  5584  26 ROLE OF OBESITY IN FEMALE REPRODUCTION. CONTEMPORARY SCIENTISTS NEED NO "P VALUE" AND "RELATIVE RISK" STATISTICS TO BE EXQUISITELY AWARE OF THE INCREASING PREVALENCE OF OBESITY AND COMPLICATIONS POSED BY OBESITY. IT IS NOW WELL RECOGNIZED THAT OBESITY IS STRONGLY ASSOCIATED WITH TYPE 2 DIABETES, HYPERTENSION, VASCULAR DISEASE, TUMORS AND REPRODUCTIVE DISORDERS. OBESE WOMEN SHOW LOWER LEVELS OF GONADOTROPIN HORMONES, REDUCED FECUNDITY, HIGHER MISCARRIAGE RATES AND POORER OUTCOMES OF IN VITRO FERTILIZATION, REVEALING THAT OBESITY AFFECTS FEMALE REPRODUCTION.

10  1373  39 DEVELOPMENTAL ORIGINS OF NONALCOHOLIC FATTY LIVER DISEASE. OBESE PREGNANT WOMEN MAY TRANSMIT THEIR METABOLIC PHENOTYPE TO OFFSPRING, LEADING TO A CYCLE OF OBESITY AND DIABETES OVER GENERATIONS. EARLY CHILDHOOD OBESITY PREDICTS NONALCOHOLIC FATTY LIVER DISEASE (NAFLD), THE MOST COMMON CHRONIC HUMAN LIVER DISEASE. THE FETUS MAY BE VULNERABLE TO STEATOSIS BECAUSE IMMATURE FETAL ADIPOSE DEPOTS ARE NOT AVAILABLE TO BUFFER THE EXCESS TRANSPLACENTAL LIPID DELIVERY IN MATERNAL OBESITY. IN ANIMAL MODELS, IN UTERO HIGH-FAT DIET EXPOSURE RESULTS IN AN INCREASE IN THE ACCUMULATION OF LIVER TRIGLYCERIDES IN OFFSPRING AND INCREASED HEPATIC OXIDATIVE STRESS AND APOPTOSIS, PERHAPS PRIMING THE LIVER FOR LATER DEVELOPMENT OF NAFLD. INNATE IMMUNE DYSFUNCTION AND NECROINFLAMMATORY CHANGES HAVE BEEN OBSERVED IN POSTNATAL OFFSPRING LIVER OF ANIMALS BORN TO HIGH-FAT-FED DAMS. POSTWEANING, LIVERS OF OFFSPRING EXPOSED TO MATERNAL HIGH-FAT FEEDING IN UTERO SHARE PATHOPHYSIOLOGIC FEATURES WITH HUMAN NAFLD, INCLUDING INCREASED DE NOVO LIPOGENESIS AND DECREASED FREE FATTY ACID OXIDATION. HUMAN STUDIES USING MAGNETIC RESONANCE IMAGING HAVE SHOWN THAT MATERNAL BMI PREDICTS INFANT INTRAHEPATOCELLULAR LIPID STORAGE, AS SEEN IN ANIMAL MODELS. THE GENERATIONAL TRANSFER OF NAFLD MAY OCCUR VIA EPIGENETIC CHANGES IN OFFSPRING LIVER. TRANSMISSION OF MICROBIOTA FROM MOTHER TO INFANT MAY IMPACT ENERGY RETENTION AND IMMUNE FUNCTION THAT CONTRIBUTE TO A PREDISPOSITION TO NAFLD.	2014	
                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                   
11  4886  32 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	
                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                        
12  4072  34 MATERNAL DNA METHYLATION SIGNATURES OF ARSENIC EXPOSURE IS ASSOCIATED WITH ADULT OFFSPRING INSULIN RESISTANCE IN THE STRONG HEART STUDY. EXPOSURE TO LOW TO MODERATE ARSENIC (AS) LEVELS HAS BEEN ASSOCIATED WITH TYPE 2 DIABETES (T2D) AND OTHER CHRONIC DISEASES IN AMERICAN INDIAN COMMUNITIES. PRENATAL EXPOSURE TO AS MAY ALSO INCREASE THE RISK FOR T2D IN ADULTHOOD, AND MATERNAL AS HAS BEEN ASSOCIATED WITH ADULT OFFSPRING METABOLIC HEALTH MEASUREMENTS. WE HYPOTHESIZED THAT T2D-RELATED OUTCOMES IN ADULT OFFSPRING BORN TO WOMEN EXPOSED TO LOW TO MODERATE AS CAN BE EVALUATED UTILIZING A MATERNALLY-DERIVED MOLECULAR BIOSIGNATURE OF AS EXPOSURE. HEREIN, WE EVALUATED THE ASSOCIATION OF MATERNAL DNA METHYLATION WITH INCIDENT T2D AND INSULIN RESISTANCE (HOMEOSTATIC MODEL ASSESSMENT OF INSULIN RESISTANCE [HOMA2-IR]) IN ADULT OFFSPRING. FOR DNA METHYLATION, WE USED 20 DIFFERENTIALLY METHYLATED CYTOSINE-GUANINE DINUCLEOTIDES (CPG) PREVIOUSLY ASSOCIATED WITH THE SUM OF INORGANIC AND METHYLATED AS SPECIES (SIGMAAS) IN URINE IN THE STRONG HEART STUDY (SHS). OF THESE 20 CPGS, WE FOUND SIX CPGS NOMINALLY ASSOCIATED (P < 0.05) WITH HOMA2-IR IN A FULLY ADJUSTED MODEL THAT INCLUDED CLINICALLY RELEVANT COVARIATES AND OFFSPRING ADIPOSITY MEASUREMENTS; A SIMILAR MODEL THAT ADJUSTED INSTEAD FOR MATERNAL ADIPOSITY MEASUREMENTS FOUND THREE CPGS NOMINALLY ASSOCIATED WITH HOMA2-IR, TWO OF WHICH OVERLAPPED THE OFFSPRING ADIPOSITY MODEL. AFTER ADJUSTING FOR MULTIPLE COMPARISONS, CG03036214 REMAINED ASSOCIATED WITH HOMA2-IR (Q < 0.10) IN THE OFFSPRING ADIPOSITY MODEL. THE ODDS RATIO OF INCIDENT T2D INCREASED WITH AN INCREASE IN MATERNAL DNA METHYLATION AT ONE HOMA2-IR ASSOCIATED CPG IN THE MODEL ADJUSTING FOR OFFSPRING ADIPOSITY, CG12116137, WHEREAS ADJUSTING FOR MATERNAL ADIPOSITY HAD A MINIMAL EFFECT ON THE ASSOCIATION. OUR DATA SUGGESTS OFFSPRING ADIPOSITY, RATHER THAN MATERNAL ADIPOSITY, POTENTIALLY INFLUENCES THE EFFECTS OF MATERNAL DNAM SIGNATURES ON OFFSPRING METABOLIC HEALTH PARAMETERS. HERE, WE HAVE PRESENTED EVIDENCE SUPPORTING A ROLE FOR EPIGENETIC BIOSIGNATURES OF MATERNAL AS EXPOSURE AS A POTENTIAL BIOMARKER FOR EVALUATING RISK OF T2D-RELATED OUTCOMES IN OFFSPRING LATER IN LIFE.	2023	
                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                   
13  6291  40 THE POTENTIAL TO FIGHT OBESITY WITH ADIPOGENESIS MODULATING COMPOUNDS. OBESITY IS AN INCREASINGLY SEVERE PUBLIC HEALTH PROBLEM, WHICH BRINGS HUGE SOCIAL AND ECONOMIC BURDENS. INCREASED BODY ADIPOSITY IN OBESITY IS NOT ONLY TIGHTLY ASSOCIATED WITH TYPE 2 DIABETES, BUT ALSO SIGNIFICANTLY INCREASES THE RISKS OF OTHER CHRONIC DISEASES INCLUDING CARDIOVASCULAR DISEASES, FATTY LIVER DISEASES AND CANCERS. ADIPOGENESIS DESCRIBES THE PROCESS OF THE DIFFERENTIATION AND MATURATION OF ADIPOCYTES, WHICH ACCUMULATE IN DISTRIBUTED ADIPOSE TISSUE AT VARIOUS SITES IN THE BODY. THE MAJOR FUNCTIONS OF WHITE ADIPOCYTES ARE TO STORE ENERGY AS FAT DURING PERIODS WHEN ENERGY INTAKE EXCEEDS EXPENDITURE AND TO MOBILIZE THIS STORED FUEL WHEN ENERGY EXPENDITURE EXCEEDS INTAKE. BROWN/BEIGE ADIPOCYTES CONTRIBUTE TO NON-SHIVERING THERMOGENESIS UPON COLD EXPOSURE AND ADRENERGIC STIMULATION, AND THEREBY PROMOTE ENERGY CONSUMPTION. THE IMBALANCE OF ENERGY INTAKE AND EXPENDITURE CAUSES OBESITY. RECENT INTEREST IN EPIGENETICS AND SIGNALING PATHWAYS HAS UTILIZED SMALL MOLECULE TOOLS AIMED AT MODIFYING OBESITY-SPECIFIC GENE EXPRESSION. IN THIS REVIEW, WE DISCUSS COMPOUNDS WITH ADIPOGENESIS-RELATED SIGNALING PATHWAYS AND EPIGENETIC MODULATING PROPERTIES THAT HAVE BEEN IDENTIFIED AS POTENTIAL THERAPEUTIC AGENTS WHICH CAST SOME LIGHT ON THE FUTURE TREATMENT OF OBESITY.	2022	
                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                               
14  3557  36 IMPACT OF BMI AND WAIST CIRCUMFERENCE ON EPIGENOME-WIDE DNA METHYLATION AND IDENTIFICATION OF EPIGENETIC BIOMARKERS IN BLOOD: AN EWAS IN MULTI-ETHNIC ASIAN INDIVIDUALS. BACKGROUND: THE PREVALENCE OF OBESITY AND ITS RELATED CHRONIC DISEASES HAVE BEEN INCREASING ESPECIALLY IN ASIAN COUNTRIES. OBESITY-RELATED GENETIC VARIANTS HAVE BEEN IDENTIFIED, BUT THESE EXPLAIN LITTLE OF THE VARIATION IN BMI. RECENT STUDIES REPORTED ASSOCIATIONS BETWEEN DNA METHYLATION AND OBESITY, MOSTLY IN NON-ASIAN POPULATIONS. METHODS: WE PERFORMED AN EPIGENOME-WIDE ASSOCIATION STUDY (EWAS) ON GENERAL ADIPOSITY (BODY MASS INDEX, BMI) AND ABDOMINAL ADIPOSITY (WAIST CIRCUMFERENCE, WC) IN 409 MULTI-ETHNIC ASIAN INDIVIDUALS AND REPLICATED BMI AND WAIST-ASSOCIATED DNA METHYLATION CPGS IDENTIFIED IN OTHER POPULATIONS. THE CROSS-LAGGED PANEL MODEL AND MENDELIAN RANDOMIZATION WERE USED TO ASSESS THE TEMPORAL RELATIONSHIP BETWEEN METHYLATION AND BMI. THE TEMPORAL RELATIONSHIP BETWEEN THE IDENTIFIED CPGS AND INFLAMMATION AND METABOLIC MARKERS WAS ALSO EXAMINED. RESULTS: EWAS IDENTIFIED 116 DNA METHYLATION CPGS INDEPENDENTLY ASSOCIATED WITH BMI AND EIGHT INDEPENDENTLY ASSOCIATED WITH WC AT FALSE DISCOVERY RATE P(FDR) < 0.05 IN 409 ASIAN SAMPLES. WE REPLICATED 110 BMI-ASSOCIATED CPGS PREVIOUSLY REPORTED IN EUROPEANS AND IDENTIFIED SIX NOVEL BMI-ASSOCIATED CPGS AND TWO NOVEL WC-ASSOCIATED CPGS. WE OBSERVED HIGH CONSISTENCY IN ASSOCIATION DIRECTION OF EFFECT COMPARED TO STUDIES IN OTHER POPULATIONS. CAUSAL RELATIONSHIP ANALYSES INDICATED THAT BMI WAS MORE LIKELY TO BE THE CAUSE OF DNA METHYLATION ALTERATION, RATHER THAN THE CONSEQUENCE. THE CAUSAL ANALYSES USING BMI-ASSOCIATED METHYLATION RISK SCORE ALSO SUGGESTED THAT HIGHER LEVELS OF THE INFLAMMATION MARKER IL-6 WERE LIKELY THE CONSEQUENCE OF METHYLATION CHANGE. CONCLUSION: OUR STUDY PROVIDES EVIDENCE OF AN ASSOCIATION BETWEEN OBESITY AND DNA METHYLATION IN MULTI-ETHNIC ASIANS AND SUGGESTS THAT OBESITY CAN DRIVE METHYLATION CHANGE. THE RESULTS ALSO SUGGESTED POSSIBLE CAUSAL INFLUENCE THAT OBESITY-RELATED METHYLATION CHANGES MIGHT HAVE ON INFLAMMATION AND LIPOPROTEIN LEVELS.	2021	
                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                              
15  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	
                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                         
16  4504  25 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	
                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                       
17  5294  31 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	
                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                      
18  3915  37 LINE-1 IN OBESITY AND CARDIOMETABOLIC DISEASES: A SYSTEMATIC REVIEW. EPIGENETIC MECHANISMS MAY PLAY AN IMPORTANT ROLE IN THE ETIOLOGY OF OBESITY AND CARDIOMETABOLIC DISEASES, BY ACTIVATING OR SILENCING THE RELATED-GENES. SCIENTIFIC EVIDENCE HAS SUGGESTED THAT LINE-1 METHYLATION IS ASSOCIATED WITH BODY COMPOSITION AND OBESITY-RELATED DISEASES, INCLUDING INSULIN RESISTANCE, TYPE 2 DIABETES MELLITUS, AND CARDIOVASCULAR DISEASE (CVD). IT ALSO HAS BEEN EVALUATED AS PREDICTOR OF WEIGHT LOSS. THE STUDIES' RESULTS ARE STILL CONFLICTING, AND POSITIVE AND NEGATIVE ASSOCIATIONS HAVE BEEN FOUND TO LINE-1 METHYLATION REGARDING ADIPOSITY AND CARDIOMETABOLIC MARKERS. OVERALL, THIS REVIEW PRESENTS OBSERVATIONAL (CROSS-SECTIONAL AND LONGITUDINAL) STUDIES AND INTERVENTIONS (DIET, EXERCISES, AND BARIATRIC SURGERY) THAT EVALUATED THE RELATIONSHIP OF THE LINE-1 METHYLATION WITH OBESITY, WEIGHT LOSS, DYSLIPIDEMIAS, HYPERTENSION, INSULIN RESISTANCE, CVD, AND METABOLIC SYNDROME. TEACHING POINTS EPIGENETIC MECHANISMS MAY PLAY AN IMPORTANT ROLE IN THE ETIOLOGY OF OBESITY AND CARDIOMETABOLIC DISEASES. MANY STUDIES HAVE RELATED METHYLATION OF LINE-1 WITH CARDIOMETABOLIC DISEASES; HOWEVER, THE RESULTS ARE STILL CONTROVERSIAL. THE RELATIONSHIP BETWEEN THE ETIOLOGY OF CHRONIC DISEASES AND THE METHYLATION OF LINE-1 IS NOT FULLY ELUCIDATED. WITH ADVANCES IN EPIGENETIC STUDIES, RELATED MECHANISMS MAY BE EARLY BIOMARKERS IN WEIGHT CHANGE AND CARDIOMETABOLIC RISK.	2019	
                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                          
19  3578  25 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	
                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                
20  4065  38 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
