1  4407 126 MOLECULAR ANALYSIS OF A MULTISTEP LUNG CANCER MODEL INDUCED BY CHRONIC INFLAMMATION REVEALS EPIGENETIC REGULATION OF P16 AND ACTIVATION OF THE DNA DAMAGE RESPONSE PATHWAY. THE MOLECULAR HALLMARKS OF INFLAMMATION-MEDIATED LUNG CARCINOGENESIS HAVE NOT BEEN FULLY CLARIFIED, MAINLY DUE TO THE SCARCITY OF APPROPRIATE ANIMAL MODELS. WE HAVE USED A SILICA-INDUCED MULTISTEP LUNG CARCINOGENESIS MODEL DRIVEN BY CHRONIC INFLAMMATION TO STUDY THE EVOLUTION OF MOLECULAR MARKERS AND GENETIC ALTERATIONS. WE ANALYZED MARKERS OF DNA DAMAGE RESPONSE (DDR), PROLIFERATIVE STRESS, AND TELOMERIC STRESS: GAMMA-H2AX, P16, P53, AND TERT. LUNG CANCER-RELATED EPIGENETIC AND GENETIC ALTERATIONS, INCLUDING PROMOTER HYPERMETHYLATION STATUS OF P16(CDKN2A), APC, CDH13, RASSF1, AND NORE1A, AS WELL AS MUTATIONS OF TP53, EPIDERMAL GROWTH FACTOR RECEPTOR, K-RAS, N-RAS, AND C-H-RAS, HAVE BEEN ALSO STUDIED. OUR RESULTS SHOWED DDR PATHWAY ACTIVATION IN PRENEOPLASTIC LESIONS, IN ASSOCIATION WITH INDUCIBLE NITRIC OXIDE SYNTHASE AND P53 INDUCTION. P16 WAS ALSO INDUCED IN EARLY TUMORIGENIC PROGRESSION AND WAS INACTIVATED IN BRONCHIOLAR DYSPLASIAS AND TUMORS. REMARKABLY, LACK OF MUTATIONS OF RAS AND EPIDERMAL GROWTH FACTOR RECEPTOR, AND A VERY LOW FREQUENCY OF TP53 MUTATIONS SUGGEST THAT THEY ARE NOT REQUIRED FOR TUMORIGENESIS IN THIS MODEL. IN CONTRAST, EPIGENETIC ALTERATIONS IN P16(CDKN2A), CDH13, AND APC, BUT NOT IN RASSF1 AND NORE1A, WERE CLEARLY OBSERVED. THESE DATA SUGGEST THE EXISTENCE OF A SPECIFIC MOLECULAR SIGNATURE OF INFLAMMATION-DRIVEN LUNG CARCINOGENESIS THAT SHARES SOME, BUT NOT ALL, OF THE MOLECULAR LANDMARKS OF CHEMICALLY INDUCED LUNG CANCER.	2007	
                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                   
2  4991  25 PEDIATRIC NON-ALCOHOLIC FATTY LIVER DISEASE: NUTRITIONAL ORIGINS AND POTENTIAL MOLECULAR MECHANISMS. NON-ALCOHOLIC FATTY LIVER DISEASE (NAFLD) IS THE NUMBER ONE CHRONIC LIVER DISEASE WORLDWIDE AND IS ESTIMATED TO AFFECT NEARLY 40% OF OBESE YOUTH AND UP TO 10% OF THE GENERAL PEDIATRIC POPULATION WITHOUT ANY OBVIOUS SIGNS OR SYMPTOMS. ALTHOUGH THE EARLY STAGES OF NAFLD ARE REVERSIBLE WITH DIET AND LIFESTYLE MODIFICATIONS, DETECTING SUCH STAGES IS HINDERED BY A LACK OF NON-INVASIVE METHODS OF RISK ASSESSMENT AND DIAGNOSIS. THIS ABSENCE OF NON-INVASIVE MEANS OF DIAGNOSIS IS DIRECTLY RELATED TO THE SCARCITY OF LONG-TERM PROSPECTIVE STUDIES OF PEDIATRIC NAFLD IN CHILDREN AND ADOLESCENTS. IN THE MAJORITY OF PEDIATRIC NAFLD CASES, THE MECHANISMS DRIVING THE ORIGIN AND RAPID PROGRESSION OF NAFLD REMAIN UNKNOWN. THE PROGRESSION FROM NAFLD TO NON-ALCOHOLIC STEATOHEPATITIS (NASH) IN YOUTH IS ASSOCIATED WITH UNIQUE HISTOLOGICAL FEATURES AND POSSIBLE IMMUNE PROCESSES AND METABOLIC PATHWAYS THAT MAY REFLECT DIFFERENT MECHANISMS COMPARED WITH ADULTS. RECENT DATA SUGGEST THAT CIRCULATING MICRORNAS (MIRNAS) ARE IMPORTANT NEW BIOMARKERS UNDERLYING PATHWAYS OF LIVER INJURY. SEVERAL FACTORS MAY CONTRIBUTE TO PEDIATRIC NAFLD DEVELOPMENT, INCLUDING HIGH-SUGAR DIETS, IN UTERO EXPOSURES VIA EPIGENETIC ALTERATIONS, CHANGES IN THE NEONATAL MICROBIOME, AND ALTERED IMMUNE SYSTEM DEVELOPMENT AND MITOCHONDRIAL FUNCTION. THIS REVIEW FOCUSES ON THE UNIQUE ASPECTS OF PEDIATRIC NAFLD AND HOW NUTRITIONAL EXPOSURES IMPACT THE IMMUNE SYSTEM, MITOCHONDRIA, AND LIVER/GASTROINTESTINAL METABOLIC HEALTH. THESE FACTORS HIGHLIGHT THE NEED FOR ANSWERS TO HOW NAFLD DEVELOPS IN CHILDREN AND FOR EARLY STAGE-SPECIFIC INTERVENTIONS.	2020	
                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                               
3  3618  26 IN VITRO MODELING OF THE NEUROBIOLOGICAL EFFECTS OF GLUCOCORTICOIDS: A REVIEW. HYPOTHALAMIC-PITUITARY ADRENAL (HPA)AXIS DYSREGULATION HAS LONG BEEN IMPLICATED IN STRESS-RELATED DISORDERS SUCH AS MAJOR DEPRESSION AND POST-TRAUMATIC STRESS DISORDER. GLUCOCORTICOIDS (GCS) ARE RELEASED FROM THE ADRENAL GLANDS AS A RESULT OF HPA-AXIS ACTIVATION. THE RELEASE OF GCS IS IMPLICATED WITH SEVERAL NEUROBIOLOGICAL CHANGES THAT ARE ASSOCIATED WITH NEGATIVE CONSEQUENCES OF CHRONIC STRESS AND THE ONSET AND COURSE OF PSYCHIATRIC DISORDERS. INVESTIGATING THE UNDERLYING NEUROBIOLOGICAL EFFECTS OF GCS MAY HELP TO BETTER UNDERSTAND THE PATHOPHYSIOLOGY OF STRESS-RELATED PSYCHIATRIC DISORDERS. GCS IMPACT A PLETHORA OF NEURONAL PROCESSES AT THE GENETIC, EPIGENETIC, CELLULAR, AND MOLECULAR LEVELS. GIVEN THE SCARCITY AND DIFFICULTY IN ACCESSING HUMAN BRAIN SAMPLES, 2D AND 3D IN VITRO NEURONAL CULTURES ARE BECOMING INCREASINGLY USEFUL IN STUDYING GC EFFECTS. IN THIS REVIEW, WE PROVIDE AN OVERVIEW OF IN VITRO STUDIES INVESTIGATING THE EFFECTS OF GCS ON KEY NEURONAL PROCESSES SUCH AS PROLIFERATION AND SURVIVAL OF PROGENITOR CELLS, NEUROGENESIS, SYNAPTIC PLASTICITY, NEURONAL ACTIVITY, INFLAMMATION, GENETIC VULNERABILITY, AND EPIGENETIC ALTERATIONS. FINALLY, WE DISCUSS THE CHALLENGES IN THE FIELD AND OFFER SUGGESTIONS FOR IMPROVING THE USE OF IN VITRO MODELS TO INVESTIGATE GC EFFECTS.	2023	
                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                              
4   116  34 A STUDY OF DNA METHYLATION OF BLADDER CANCER BIOMARKERS IN THE URINE OF PATIENTS WITH NEUROGENIC LOWER URINARY TRACT DYSFUNCTION. BACKGROUND: BLADDER CANCER (BCA) IN PATIENTS SUFFERING FROM NEUROGENIC LOWER URINARY TRACT DYSFUNCTION (NLUTD) IS A SIGNIFICANT CONCERN DUE TO ITS ADVANCED STAGE AT DIAGNOSIS AND HIGH MORTALITY RATE. CURRENTLY, THERE IS A SCARCITY OF SPECIFIC GUIDELINES FOR BCA SCREENING IN THESE PATIENTS. THE DEVELOPMENT OF URINE BIOMARKERS FOR BCA SEEMS TO BE AN ATTRACTIVE NON-INVASIVE METHOD OF SCREENING OR RISK STRATIFICATION IN THIS PATIENT POPULATION. DNA METHYLATION IS AN EPIGENETIC MODIFICATION, RESULTING IN THE TRANSCRIPTIONAL SILENCING OF TUMOR SUPPRESSION GENES, THAT IS FREQUENTLY DETECTED IN THE URINE OF BCA PATIENTS. OBJECTIVES: WE AIMED TO INVESTIGATE DNA HYPERMETHYLATION IN FIVE GENE PROMOTERS, PREVIOUSLY ASSOCIATED WITH BCA, IN THE URINE OF NLUTD PATIENTS, AND IN COMPARISON WITH HEALTHY CONTROLS. DESIGN, SETTING AND PARTICIPANTS: THIS WAS A PROSPECTIVE CASE-CONTROL STUDY THAT RECRUITED NEUROUROLOGY OUTPATIENTS FROM A PUBLIC TEACHING HOSPITAL WHO HAD SUFFERED FROM NLUTD FOR AT LEAST 5 YEARS. THEY ALL UNDERWENT CYSTOSCOPY COMBINED WITH BIOPSY FOR BCA SCREENING FOLLOWING WRITTEN INFORMED CONSENT. DNA WAS EXTRACTED AND DNA METHYLATION WAS ASSESSED FOR THE RASSF1, RARBETA, DAPK, TERT AND APC GENE PROMOTERS VIA QUANTITATIVE METHYLATION-SPECIFIC PCR IN URINE SPECIMENS FROM THE PATIENTS AND CONTROLS. RESULTS: FORTY-ONE PATIENTS OF MIXED NLUTD ETIOLOGY AND 35 CONTROLS WERE ENROLLED. DNA WAS DETECTED IN 36 PATIENTS' URINE SPECIMENS AND IN THOSE OF 22 CONTROLS. IN THE URINE SPECIMENS, DNA WAS HYPERMETHYLATED IN AT LEAST ONE OF FIVE GENE PROMOTERS IN 17/36 PATIENTS AND IN 3/22 CONTROLS (47.22% VS. 13.64%, RESPECTIVELY, P = 0.009). RASSF1 WAS HYPERMETHYLATED IN 10/17 (58.82%) SPECIMENS WITH DETECTED METHYLATION, APC IN 7/17 (41.18%), DAPK IN 4/17 (23.53%), RAR-BETA2 IN 3/17 (17.56%) AND TERT IN NONE. ACCORDING TO A MULTIVARIATE LOGISTIC REGRESSION ANALYSIS, NLUTD AND MALE GENDER WERE SIGNIFICANTLY ASSOCIATED WITH HYPERMETHYLATION (OR = 7.43, P = 0.007 AND OR = 4.21; P = 0.04, RESPECTIVELY). IN THE TISSUE SPECIMENS, HISTOLOGY REVEALED TALG BCA IN TWO PATIENTS AND UROTHELIAL SQUAMOUS METAPLASIA IN FIVE PATIENTS. CHRONIC BLADDER INFLAMMATION WAS PRESENT IN 35/41 BLADDER BIOPSIES. CONCLUSIONS: DNA HYPERMETHYLATION IN A PANEL OF FIVE BCA-ASSOCIATED GENES IN THE URINE WAS SIGNIFICANTLY MORE FREQUENT IN NLUTD PATIENTS THAN IN THE CONTROLS. OUR RESULTS WARRANT FURTHER EVALUATION IN LONGITUDINAL STUDIES ASSESSING THE CLINICAL IMPLICATIONS AND POSSIBLE ASSOCIATIONS BETWEEN DNA HYPERMETHYLATION, CHRONIC INFLAMMATION AND BCA IN THE NLUTD POPULATION.	2023	
                   
5  6315  33 THE RELATIONSHIP OF MATERNAL AND CHILD METHYLATION OF THE GLUCOCORTICOID RECEPTOR NR3C1 DURING EARLY CHILDHOOD AND SUBSEQUENT CHILD PSYCHOPATHOLOGY AT SCHOOL-AGE IN THE CONTEXT OF MATERNAL INTERPERSONAL VIOLENCE-RELATED POST-TRAUMATIC STRESS DISORDER. INTRODUCTION: INTERPERSONAL VIOLENT (IPV) EXPERIENCES WHEN THEY BEGIN IN CHILDHOOD AND CONTINUE IN VARIOUS FORMS DURING ADULTHOOD OFTEN LEAD TO CHRONIC POST-TRAUMATIC STRESS DISORDER (PTSD) THAT IS ASSOCIATED IN MULTIPLE STUDIES WITH HYPOCORTISOLISM AND LOWER PERCENTAGE OF METHYLATION OF THE PROMOTER REGION OF THE GENE CODING FOR THE GLUCOCORTICOID RECEPTOR (NR3C1). THIS PROSPECTIVE, LONGITUDINAL STUDY EXAMINED THE RELATIONSHIP OF NR3C1 METHYLATION AMONG MOTHERS WITH IPV-RELATED PTSD AND THEIR TODDLERS AND THEN LOOKED AT THE RELATIONSHIP OF MATERNAL NR3C1 METHYLATION AND CHILD PSYCHOPATHOLOGY AT SCHOOL AGE. METHODS: FORTY-EIGHT MOTHERS WERE EVALUATED FOR LIFE-EVENTS HISTORY AND POST-TRAUMATIC STRESS DISORDER VIA STRUCTURED CLINICAL INTERVIEW WHEN THEIR CHILDREN WERE AGES 12-42 MONTHS (MEAN AGE 26.7 MONTHS, SD 8.8). THEIR CHILDREN'S PSYCHOPATHOLOGY IN TERMS OF INTERNALIZING SYMPTOMS AND EXTERNALIZING BEHAVIORS WAS EVALUATED USING THE CHILD BEHAVIOR CHECKLIST AT AGES 5-9 YEARS (MEAN AGE 7 YEARS, SD 1.1). PERCENTAGE OF METHYLATION FOR THE NR3C1 GENE PROMOTER REGION WAS ASSESSED FROM DNA EXTRACTED FROM MATERNAL AND CHILD SALIVA USING BISULFITE PYROSEQUENCING. DATA ANALYSIS INVOLVED PARAMETRIC AND NON-PARAMETRIC CORRELATIONS AND MULTIPLE LINEAR AND LOGISTIC REGRESSION MODELING. RESULTS: LOGISTIC REGRESSION MODELS USING CHILD NR3C1 METHYLATION AS THE DEPENDENT VARIABLE AND MATERNAL NR3C1 METHYLATION AND PTSD GROUP STATUS AS PREDICTORS, AS WELL AS THE INTERACTION INDICATED THAT ALL THREE OF THESE SIGNIFICANTLY PREDICTED CHILD NR3C1 METHYLATION. THESE FINDINGS REMAINED SIGNIFICANT WHEN CONTROLLING FOR CHILD AGE, SEX AND MATERNAL CHILD ABUSE HISTORY. OVERALL, MATERNAL NR3C1 METHYLATION WHEN CHILDREN WERE TODDLERS WAS NEGATIVELY AND SIGNIFICANTLY ASSOCIATED WITH CHILD EXTERNALIZING BEHAVIOR SEVERITY AT SCHOOL AGE. DISCUSSION: WE FOUND THAT CORRELATIONS BETWEEN MOTHERS AND THEIR CHILDREN OF NR3C1 METHYLATION LEVELS OVERALL AND AT ALL INDIVIDUAL CPG SITES OF INTEREST WERE SIGNIFICANT ONLY IN THE IPV-PTSD GROUP. THE LATTER FINDINGS SUPPORT THAT NR3C1 METHYLATION IN MOTHERS POSITIVELY AND STATISTICALLY SIGNIFICANTLY CORRELATES WITH NR3C1 METHYLATION IN THEIR CHILDREN ONLY IN PRESENCE OF IPV-PTSD IN THE MOTHERS. THIS MATERNAL EPIGENETIC SIGNATURE WITH RESPECT TO THIS GLUCOCORTICOID RECEPTOR IS SIGNIFICANTLY ASSOCIATED WITH CHILD BEHAVIOR THAT MAY WELL POSE A RISK FOR INTERGENERATIONAL TRANSMISSION OF VIOLENCE AND RELATED PSYCHOPATHOLOGY.	2022	

6  5200  26 PRENATAL MATERNAL STRESS PREDICTS METHYLATION OF GENES REGULATING THE HYPOTHALAMIC-PITUITARY-ADRENOCORTICAL SYSTEM IN MOTHERS AND NEWBORNS IN THE DEMOCRATIC REPUBLIC OF CONGO. EXPOSURE TO STRESS EARLY IN LIFE PERMANENTLY SHAPES ACTIVITY OF THE HYPOTHALAMIC-PITUITARY-ADRENOCORTICAL (HPA) AXIS AND THE BRAIN. PRENATALLY, GLUCOCORTICOIDS PASS THROUGH THE PLACENTA TO THE FETUS WITH POSTNATAL IMPACTS ON BRAIN DEVELOPMENT, BIRTH WEIGHT (BW), AND HPA AXIS FUNCTIONING. LITTLE IS KNOWN ABOUT THE BIOLOGICAL MECHANISMS BY WHICH PRENATAL STRESS AFFECTS POSTNATAL FUNCTIONING. THIS STUDY ADDRESSES THIS GAP BY EXAMINING THE EFFECT OF CHRONIC STRESS AND TRAUMATIC WAR-RELATED STRESS ON EPIGENETIC CHANGES IN FOUR KEY GENES REGULATING THE HPA AXIS IN NEONATAL CORD BLOOD, PLACENTA, AND MATERNAL BLOOD: CRH, CRHBP, NR3C1, AND FKBP5. PARTICIPANTS WERE 24 MOTHER-NEWBORN DYADS IN THE CONFLICT-RIDDEN REGION OF THE EASTERN DEMOCRATIC REPUBLIC OF CONGO. BW DATA WERE COLLECTED AT DELIVERY AND MATERNAL INTERVIEWS WERE CONDUCTED TO ASSESS CULTURALLY RELEVANT CHRONIC AND WAR-RELATED STRESSORS. CHRONIC STRESS AND WAR TRAUMA HAD WIDESPREAD EFFECTS ON HPA AXIS GENE METHYLATION, WITH SIGNIFICANT EFFECTS OBSERVED AT TRANSCRIPTION FACTOR BINDING (TFB) SITES IN ALL TARGET GENES TESTED. SOME CHANGES IN METHYLATION WERE UNIQUE TO CHRONIC OR WAR STRESS, WHEREAS OTHERS WERE OBSERVED ACROSS BOTH STRESSOR TYPES. MOREOVER, STRESS EXPOSURES IMPACTED MATERNAL AND FETAL TISSUES DIFFERENTLY, SUPPORTING THEORETICAL MODELS THAT STRESS IMPACTS VARY ACCORDING TO LIFE PHASE. METHYLATION IN SEVERAL NR3C1 AND CRH CPG SITES, ALL LOCATED AT TFB SITES, WAS ASSOCIATED WITH BW. THESE FINDINGS SUGGEST THAT PRENATAL STRESS EXPOSURE IMPACTS DEVELOPMENT VIA EPIGENETIC CHANGES IN HPA AXIS GENES.	2016	
                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                
7  6478  23 TOPICAL REVIEW: THE EMERGING FIELD OF EPIGENETICS: INFORMING MODELS OF PEDIATRIC TRAUMA AND PHYSICAL HEALTH. OBJECTIVE: TRAUMA EXPERIENCED DURING CHILDHOOD AND ADOLESCENCE HAS BEEN LINKED TO A NUMBER OF CHRONIC MEDICAL CONCERNS. WE HIGHLIGHT MAJOR FINDINGS FROM THE PEDIATRIC TRAUMA LITERATURE TO PROVIDE A MODEL FOR UNDERSTANDING THIS ASSOCIATION. METHODS: STUDIES EXAMINING THE EFFECTS OF TRAUMA WERE SYSTEMATICALLY REVIEWED AND SYNTHESIZED INTO A MODEL PROPOSING A CENTRAL ROLE FOR EPIGENETICS IN THE WAYS THAT CHILDHOOD EXPERIENCES CAN AFFECT HEALTH. RESULTS: EARLY HYPOTHALAMIC PITUITARY ADRENAL (HPA) AXIS RESPONSE MAY IMPACT INITIAL TRAUMA EXPERIENCE, WITH DOWNSTREAM EFFECTS ON POSTTRAUMA ADJUSTMENT REFLECTED IN POSTTRAUMA NEUROBIOLOGY, PSYCHOLOGICAL HEALTH, AND PHYSICAL HEALTH. CONCLUSIONS: PROSPECTIVE RESEARCH WITH CHILDREN AND ADOLESCENTS EXPOSED TO TRAUMA IS NEEDED TO BETTER CHARACTERIZE THE GENETIC AND EPIGENETIC INFLUENCES ON THE COURSE OF HPA AND IMMUNE PROCESSES AS RELATED TO POSTTRAUMA PSYCHOLOGICAL AND PHYSICAL HEALTH OUTCOMES.	2016	
                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                  
8  2207  29 EPIGENETIC MODIFICATIONS AND GLUCOCORTICOID SENSITIVITY IN MYALGIC ENCEPHALOMYELITIS/CHRONIC FATIGUE SYNDROME (ME/CFS). BACKGROUND: MYALGIC ENCEPHALOMYELITIS/CHRONIC FATIGUE SYNDROME (ME/CFS) IS A DEBILITATING IDIOPATHIC DISEASE CHARACTERIZED BY UNEXPLAINED FATIGUE THAT FAILS TO RESOLVE WITH SUFFICIENT REST. DIAGNOSIS IS BASED ON A LIST OF SYMPTOMS AND EXCLUSION OF OTHER FATIGUE-RELATED HEALTH CONDITIONS. DESPITE A HETEROGENEOUS PATIENT POPULATION, IMMUNE AND HYPOTHALAMIC-PITUITARY-ADRENAL (HPA) AXIS FUNCTION DIFFERENCES, SUCH AS ENHANCED NEGATIVE FEEDBACK TO GLUCOCORTICOIDS, ARE RECURRING FINDINGS IN ME/CFS STUDIES. EPIGENETIC MODIFICATIONS, SUCH AS CPG METHYLATION, ARE KNOWN TO REGULATE LONG-TERM PHENOTYPIC DIFFERENCES AND PREVIOUS WORK BY OUR GROUP FOUND DNA METHYLOME DIFFERENCES IN ME/CFS, HOWEVER THE RELATIONSHIP BETWEEN DNA METHYLOME MODIFICATIONS, CLINICAL AND FUNCTIONAL CHARACTERISTICS ASSOCIATED WITH ME/CFS HAS NOT BEEN EXAMINED. METHODS: WE EXAMINED THE DNA METHYLOME IN PERIPHERAL BLOOD MONONUCLEAR CELLS (PBMCS) OF A LARGER COHORT OF FEMALE ME/CFS PATIENTS USING THE ILLUMINA HUMANMETHYLATION450 BEADCHIP ARRAY. IN PARALLEL TO THE DNA METHYLOME ANALYSIS, WE INVESTIGATED IN VITRO GLUCOCORTICOID SENSITIVITY DIFFERENCES BY STIMULATING PBMCS WITH PHYTOHAEMAGGLUTININ AND SUPPRESSED GROWTH WITH DEXAMETHASONE. WE EXPLORED DNA METHYLATION DIFFERENCES USING BISULFITE PYROSEQUENCING AND STATISTICAL PERMUTATION. LINEAR REGRESSION WAS IMPLEMENTED TO DISCOVER EPIGENOMIC REGIONS ASSOCIATED WITH SELF-REPORTED QUALITY OF LIFE AND NETWORK ANALYSIS OF GENE ONTOLOGY TERMS TO BIOLOGICALLY CONTEXTUALIZE RESULTS. RESULTS: WE DETECTED 12,608 DIFFERENTIALLY METHYLATED SITES BETWEEN ME/CFS PATIENTS AND HEALTHY CONTROLS PREDOMINANTLY LOCALIZED TO CELLULAR METABOLISM GENES, SOME OF WHICH WERE ALSO RELATED TO SELF-REPORTED QUALITY OF LIFE HEALTH SCORES. AMONG ME/CFS PATIENTS, GLUCOCORTICOID SENSITIVITY WAS ASSOCIATED WITH DIFFERENTIAL METHYLATION AT 13 LOCI. CONCLUSIONS: OUR RESULTS INDICATE DNA METHYLATION MODIFICATIONS IN CELLULAR METABOLISM IN ME/CFS DESPITE A HETEROGENEOUS PATIENT POPULATION, IMPLICATING THESE PROCESSES IN IMMUNE AND HPA AXIS DYSFUNCTION IN ME/CFS. MODIFICATIONS TO EPIGENETIC LOCI ASSOCIATED WITH DIFFERENCES IN GLUCOCORTICOID SENSITIVITY MAY BE IMPORTANT AS BIOMARKERS FOR FUTURE CLINICAL TESTING. OVERALL, THESE FINDINGS ALIGN WITH RECENT ME/CFS WORK THAT POINT TOWARDS IMPAIRMENT IN CELLULAR ENERGY PRODUCTION IN THIS PATIENT POPULATION.	2017	
                                                                                                                                                                                                                                              
9  1058  25 CLINICAL MEASURES OF ALLOSTATIC LOAD IN CHILDREN AND ADOLESCENTS WITH FOOD ALLERGY, DEPRESSION, OR ANXIETY. PURPOSE: SUSTAINED HIGH STRESS EXPOSURE RESULTS IN CHRONIC ACTIVATION OF THE STRESS RESPONSE SYSTEM, DYSREGULATED STRESS RESPONSES, HIGH ALLOSTATIC LOAD, AND POOR LATER-LIFE HEALTH. CHILDREN AND ADOLESCENTS WITH CHRONIC HEALTH CONDITIONS FACE STRESSORS RELATED TO THEIR CONDITION IN ADDITION TO THOSE TYPICAL OF CHILDHOOD AND ADOLESCENCE, PLACING THEM AT RISK OF HIGH ALLOSTATIC LOAD. THE PURPOSE OF THIS SECONDARY ANALYSIS WAS TO EXAMINE WHETHER YOUTH WITH CHRONIC HEALTH CONDITIONS DIFFER FROM CONTROLS ON CLINICAL MEASURES OF ALLOSTATIC LOAD. DESIGN AND METHODS: A SECONDARY ANALYSIS OF TWO DATASETS, THE ELECTRONIC HEALTH RECORD OF A TERTIARY CHILDREN'S HOSPITAL AND DATA FROM THE SURVEY OF THE HEALTH OF WISCONSIN, COMPARED YOUTH WITH CHRONIC HEALTH CONDITIONS TO CONTROLS ON CLINICAL MEASURES OF ALLOSTATIC LOAD. ADDITIONAL ANALYSES EXPLORED WHETHER PARENTAL STRESS AND MENTAL HEALTH INFLUENCED THESE RELATIONSHIPS. RESULTS: ANALYSES IDENTIFIED DIFFERENCES IN BMI, BLOOD PRESSURE, AND WAIST CIRCUMFERENCE BETWEEN YOUTH WITH FOOD ALLERGY, ANXIETY, OR DEPRESSION, AND CONTROLS. THESE RELATIONSHIPS DIFFERED FOR MALES AND FEMALES AND FOR THOSE WITH COMORBID MENTAL AND PHYSICAL CONDITIONS, AND WERE INFLUENCED BY PARENT STRESS AND MENTAL HEALTH. CONCLUSIONS: RESULTS SUPPORT FUTURE STUDIES EXPLORING WHETHER HIGH STRESS IN YOUTH WITH CHRONIC HEALTH CONDITIONS LEADS TO INCREASED ALLOSTATIC LOAD. INCORPORATING BIOMARKERS AS WELL AS GENETIC AND EPIGENETIC FACTORS WILL PROVIDE CRITICAL INSIGHTS. PRACTICE IMPLICATIONS: YOUTH WITH MENTAL AND PHYSICAL CHCS MAY BE AT INCREASED RISK OF HIGH ALLOSTATIC LOAD, REFLECTED IN CLINICAL MEASURES OF METABOLISM, AND SHOULD HAVE REGULAR ASSESSMENTS OF THEIR METABOLIC HEALTH.	2021	
                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                               
10  3294  32 HIGH INCIDENCE OF MGMT AND RARBETA PROMOTER METHYLATION IN PRIMARY GLIOBLASTOMAS: ASSOCIATION WITH HISTOPATHOLOGICAL CHARACTERISTICS, INFLAMMATORY MEDIATORS AND CLINICAL OUTCOME. GLIOBLASTOMAS, THE MOST FREQUENT PRIMARY BRAIN TUMORS IN ADULTS, ARE CHARACTERIZED BY A HIGHLY AGGRESSIVE, INFLAMMATORY AND ANGIOGENIC PHENOTYPE. METHYLATION OF CPG ISLANDS IN CANCER-RELATED GENES MAY SERVE AS AN EPIGENETIC BIOMARKER FOR GLIOBLASTOMA DIAGNOSIS AND PROGNOSIS. THE AIM OF THIS STUDY WAS TO ANALYZE THE METHYLATION STATUS OF FOUR CRITICAL TUMOR-ASSOCIATED GENES (MGMT, RARBETA, RASSF1A, CDH13), AND INVESTIGATE POSSIBLE LINKS WITH INFLAMMATORY (INTERLEUKIN [IL]-6, IL-8) AND ANGIOGENIC MEDIATORS (VASCULAR ENDOTHELIAL GROWTH FACTOR [VEGF], CYCLOOXYGENASE [COX]-2) AND CLINICAL OUTCOME IN 23 GLIOMA SAMPLES (6 GRADE II ASTROCYTOMAS, 17 GRADE IV GLIOBLASTOMAS). RARBETA AND MGMT GENES WERE MORE FREQUENTLY METHYLATED IN 70.58% AND 58.8% OF GLIOBLASTOMAS, RESPECTIVELY. RASSF1A AND CDH13 DISPLAYED A SIMILAR METHYLATION FREQUENCY (23.52%) IN GLIOBLASTOMAS. NO GENE METHYLATION WAS OBSERVED IN GRADE II ASTROCYTOMAS. TUMOR GRADE CORRELATED POSITIVELY WITH MGMT AND RARBETA METHYLATION (P = 0.005 AND P = 0.019, RESPECTIVELY) AND THE EXTENT OF NECROSIS (P = 0.001 AND P = 0.003). INTERESTINGLY, THE MARKER OF CHRONIC INFLAMMATION, IL-6, WAS POSITIVELY ASSOCIATED WITH METHYLATION OF MGMT (P = 0.004), RARBETA (P = 0.002), AND RASSF1A (P = 0.0081) AS WELL AS THE TOTAL NUMBER OF METHYLATED GENES (P < 0.0001), INDICATING THE IMPORTANT ROLE OF IL-6 IN MAINTAINING PROMOTER METHYLATION OF THESE GENES. VEGF EXPRESSION CORRELATED POSITIVELY WITH MGMT AND RARBETA METHYLATION ALTHOUGH THESE RELATIONSHIPS WERE OF MARGINAL SIGNIFICANCE (P = 0.0679 AND P = 0.0757). KAPLAN-MEIER UNIVARIATE SURVIVAL ANALYSIS INDICATED AN UNFAVORABLE SURVIVAL PERIOD IN PATIENTS WITH MGMT METHYLATION COMPARED WITH THOSE WITHOUT METHYLATION (P = 0.0474). OUR STUDY HIGHLIGHTS THE IMPLICATION OF MGMT AND RARBETA METHYLATION IN THE AGGRESSIVE PHENOTYPE OF PRIMARY GLIOBLASTOMAS. THE ASSOCIATION OF MGMT METHYLATION WITH CLINICAL OUTCOME INDICATES ITS POTENTIAL PROGNOSTIC VALUE.	2010	
                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                 
11   325  28 ALLELE-SPECIFIC DNA METHYLATION LEVEL OF FKBP5 IS ASSOCIATED WITH POST-TRAUMATIC STRESS DISORDER. BACKGROUND: FK506-BINDING PROTEIN 5 (FKBP5) BINDS TO GLUCOCORTICOID RECEPTORS AND MODULATES GLUCOCORTICOID SENSITIVITY. THE FKBP5 GENE HAS BEEN IMPLICATED IN THE DYSREGULATION OF HUMAN STRESS RESPONSES, CONTRIBUTING TO THE RISK AND TREATMENT RESPONSE OF STRESS-RELATED DISORDERS. THE PRESENT STUDY EXAMINED WHETHER EPIGENETIC CHANGES IN FKBP5 ARE ASSOCIATED WITH CHRONIC POST-TRAUMATIC STRESS DISORDER (PTSD) STATUS IN THE CONTEXT OF FKBP5 GENETIC VARIATION (RS1360780 POLYMORPHISM) AMONG MALE VETERANS EXPOSED TO COMBAT TRAUMA. METHODS: KOREAN MALE VETERANS WHO SERVED ON ACTIVE DUTY DURING THE VIETNAM WAR WERE CATEGORIZED INTO 2 GROUPS: WITH PTSD (N = 123) AND WITHOUT PTSD (N = 116). THE GENOTYPE OF FKBP5 RS1360780 AND DNA METHYLATION LEVELS OF TWO CPG SITES AT THE FKBP5 INTRON 7 REGION WERE ASSESSED IN PERIPHERAL BLOOD. ANALYSIS OF COVARIANCE WAS PERFORMED TO EXAMINE MAIN AND INTERACTION EFFECTS OF PTSD STATUS AND FKBP5 GENOTYPE ON FKBP5 DNA METHYLATION LEVEL, WITH AGE, TRAUMA LEVELS, AND ALCOHOL USE AS COVARIATES. RESULTS: A SIGNIFICANT MAIN EFFECT OF FKBP5 RS1360780 AND PTSD AND AN INTERACTION EFFECT BETWEEN GENOTYPE AND PTSD STATUS WERE FOUND ON MEAN FKBP5 DNA METHYLATION LEVEL. THE T ALLELE OF RS1360780 WAS ASSOCIATED WITH LOWER FKBP5 METHYLATION LEVEL. IN ADDITION, THE PTSD GROUP SHOWED SIGNIFICANTLY HIGHER METHYLATION THAN DID THE NON-PTSD GROUP AMONG VETERANS CARRYING THE RISK T ALLELE (N = 96), WHILE NO GROUP DIFFERENCE WAS OBSERVED ON METHYLATION LEVELS AMONG VETERANS WITH THE CC GENOTYPE (N = 143). AMONG VETERANS CARRYING THE T ALLELE, FKBP5 METHYLATION LEVELS WERE POSITIVELY CORRELATED WITH THE SEVERITY OF PTSD SYMPTOMS. CONCLUSIONS: THE PRESENT STUDY DEMONSTRATED DIFFERENT FKBP5 METHYLATION LEVELS IN PTSD DEPENDING ON FKBP5 GENETIC VARIATION AMONG VETERANS EXPOSED TO COMBAT TRAUMA. THE PRESENT FINDING SUGGESTS THAT THE GENETIC AND EPIGENETIC MODULATION OF FKBP5 IS INVOLVED IN THE PATHOPHYSIOLOGY OF PTSD. FURTHER LONGITUDINAL RESEARCH INVOLVING PEOPLE EXPOSED TO TRAUMA IS REQUIRED TO UNDERSTAND CAUSAL RELATIONSHIPS OF FKBP5 IN THE DEVELOPMENT AND RECOVERY OF PTSD.	2019	
                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                
12  1971  25 EPIGENETIC ALTERATIONS ASSOCIATED WITH CHILDHOOD TRAUMA AND ADULT MENTAL HEALTH OUTCOMES: A SYSTEMATIC REVIEW. OBJECTIVES: MULTIPLE, CHRONIC AND REPEATED TRAUMA EXPOSURE IN CHILDHOOD IS ASSOCIATED WITH ADVERSE MENTAL HEALTH OUTCOMES IN ADULTHOOD. IN THIS PAPER WE SYNTHESISE THE LITERATURE ON EPIGENETIC MODIFICATIONS IN CHILDHOOD TRAUMA (CT) AND THE MEDIATING EFFECTS OF DIFFERENTIAL EPIGENETIC MECHANISMS ON THE ASSOCIATION BETWEEN CT AND THE LATER ONSET OF PSYCHIATRIC DISORDERS.METHODS: WE REVIEWED THE LITERATURE UP TO MARCH 2018 IN FOUR DATABASES: PUBMED, WEB OF SCIENCE, EBSCOHOST AND SCOPUS. NON-HUMAN STUDIES WERE EXCLUDED. ALL STUDIES INVESTIGATING CT EXPOSURE BOTH IN HEALTHY ADULTS (18 YEARS AND OLDER) AND ADULTS WITH PSYCHIATRIC DISORDERS WERE INCLUDED.RESULTS: THIRTY-SIX PUBLICATIONS WERE INCLUDED. FOR MOOD DISORDERS, METHYLATION OF THE GLUCOCORTICOID RECEPTOR NR3C1 GENE, SPECIFICALLY AT THE NGFI-A BINDING SITE IN EXON 1F, AND CORRELATION WITH CT WAS A ROBUST FINDING. SEVERAL STUDIES DOCUMENTED DIFFERENTIAL METHYLATION OF SLC6A4, BDNF, OXTR AND FKBP5 IN ASSOCIATION WITH CT.

13  6329  25 THE ROLE OF CHILDHOOD TRAUMA IN BIPOLAR DISORDERS. THIS REVIEW WILL DISCUSS THE ROLE OF CHILDHOOD TRAUMA IN BIPOLAR DISORDERS. RELEVANT STUDIES WERE IDENTIFIED VIA MEDLINE (PUBMED) AND PSYCINFO DATABASES PUBLISHED UP TO AND INCLUDING JULY 2015. THIS REVIEW CONTRIBUTES TO A NEW UNDERSTANDING OF THE NEGATIVE CONSEQUENCES OF EARLY LIFE STRESS, AS WELL AS SETTING CHILDHOOD TRAUMA IN A BIOLOGICAL CONTEXT OF SUSCEPTIBILITY AND DISCUSSING NOVEL LONG-TERM PATHOPHYSIOLOGICAL CONSEQUENCES IN BIPOLAR DISORDERS. CHILDHOOD TRAUMATIC EVENTS ARE RISK FACTORS FOR DEVELOPING BIPOLAR DISORDERS, IN ADDITION TO A MORE SEVERE CLINICAL PRESENTATION OVER TIME (PRIMARILY AN EARLIER AGE AT ONSET AND AN INCREASED RISK OF SUICIDE ATTEMPT AND SUBSTANCE MISUSE). CHILDHOOD TRAUMA LEADS TO ALTERATIONS OF AFFECT REGULATION, IMPULSE CONTROL, AND COGNITIVE FUNCTIONING THAT MIGHT DECREASE THE ABILITY TO COPE WITH LATER STRESSORS. CHILDHOOD TRAUMA INTERACTS WITH SEVERAL GENES BELONGING TO SEVERAL DIFFERENT BIOLOGICAL PATHWAYS [HYPOTHALAMIC-PITUITARY-ADRENAL (HPA) AXIS, SEROTONERGIC TRANSMISSION, NEUROPLASTICITY, IMMUNITY, CALCIUM SIGNALING, AND CIRCADIAN RHYTHMS] TO DECREASE THE AGE AT THE ONSET OF THE DISORDER OR INCREASE THE RISK OF SUICIDE. EPIGENETIC FACTORS MAY ALSO BE INVOLVED IN THE NEUROBIOLOGICAL CONSEQUENCES OF CHILDHOOD TRAUMA IN BIPOLAR DISORDER. BIOLOGICAL SEQUELAE SUCH AS CHRONIC INFLAMMATION, SLEEP DISTURBANCE, OR TELOMERE SHORTENING ARE POTENTIAL MEDIATORS OF THE NEGATIVE EFFECTS OF CHILDHOOD TRAUMA IN BIPOLAR DISORDERS, IN PARTICULAR WITH REGARD TO PHYSICAL HEALTH. THE MAIN CLINICAL IMPLICATION IS TO SYSTEMATICALLY ASSESS CHILDHOOD TRAUMA IN PATIENTS WITH BIPOLAR DISORDERS, OR AT LEAST IN THOSE WITH A SEVERE OR INSTABLE COURSE. THE CHALLENGE FOR THE NEXT YEARS WILL BE TO FILL THE GAP BETWEEN CLINICAL AND FUNDAMENTAL RESEARCH AND ROUTINE PRACTICE, SINCE RECOMMENDATIONS FOR MANAGING THIS SPECIFIC POPULATION ARE LACKING. IN PARTICULAR, LITTLE IS KNOWN ON WHICH PSYCHOTHERAPIES SHOULD BE PROVIDED OR WHICH TARGETS THERAPISTS SHOULD FOCUS ON, AS WELL AS HOW CHILDHOOD TRAUMA COULD EXPLAIN THE RESISTANCE TO MOOD STABILIZERS.	2016	
                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                       
14  5827  28 STRESS, BURNOUT AND DEPRESSION: A SYSTEMATIC REVIEW ON DNA METHYLATION MECHANISMS. DESPITE THAT BURNOUT PRESENTS A SERIOUS BURDEN FOR MODERN SOCIETY, THERE ARE NO DIAGNOSTIC CRITERIA. ADDITIONAL DIFFICULTY IS THE DIFFERENTIAL DIAGNOSIS WITH DEPRESSION. CONSEQUENTLY, THERE IS A NEED TO DISPOSE OF A BURNOUT BIOMARKER. EPIGENETIC STUDIES SUGGEST THAT DNA METHYLATION IS A POSSIBLE MEDIATOR LINKING INDIVIDUAL RESPONSE TO STRESS AND PSYCHOPATHOLOGY AND COULD BE CONSIDERED AS A POTENTIAL BIOMARKER OF STRESS-RELATED MENTAL DISORDERS. THUS, THE AIM OF THIS REVIEW IS TO PROVIDE AN OVERVIEW OF DNA METHYLATION MECHANISMS IN STRESS, BURNOUT AND DEPRESSION. IN ADDITION TO STATE-OF-THE-ART OVERVIEW, THE GOAL OF THIS REVIEW IS TO PROVIDE A SCIENTIFIC BASE FOR BURNOUT BIOMARKER RESEARCH. WE PERFORMED A SYSTEMATIC LITERATURE SEARCH AND IDENTIFIED 25 PERTINENT ARTICLES. AMONG THESE, 15 FOCUSED ON DEPRESSION, 7 ON CHRONIC STRESS AND ONLY 3 ON WORK STRESS/BURNOUT. THREE EPIGENOME-WIDE STUDIES WERE IDENTIFIED AND THE MAJORITY OF STUDIES USED THE CANDIDATE-GENE APPROACH, ASSESSING 12 DIFFERENT GENES. THE GLUCOCORTICOID RECEPTOR GENE (NR3C1) DISPLAYED DIFFERENT METHYLATION PATTERNS IN CHRONIC STRESS AND DEPRESSION. THE SEROTONIN TRANSPORTER GENE (SLC6A4) METHYLATION WAS SIMILARLY AFFECTED IN STRESS, DEPRESSION AND BURNOUT. WORK-RELATED STRESS AND DEPRESSIVE SYMPTOMS WERE ASSOCIATED WITH DIFFERENT METHYLATION PATTERNS OF THE BRAIN DERIVED NEUROTROPHIC FACTOR GENE (BDNF) IN THE SAME HUMAN SAMPLE. THE TYROSINE HYDROXYLASE (TH) METHYLATION WAS CORRELATED WITH WORK STRESS IN A SINGLE STUDY. ADDITIONAL, THOROUGHLY DESIGNED LONGITUDINAL STUDIES ARE NECESSARY FOR REVEALING THE CAUSE-EFFECT RELATIONSHIP OF WORK STRESS, EPIGENETICS AND BURNOUT, INCLUDING ITS OVERLAP WITH DEPRESSION.	2017	
                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                          
15  5962  29 TELOMERES, OXIDATIVE STRESS, AND TIMING FOR SPONTANEOUS TERM AND PRETERM LABOR. TELOMERES ARE NUCLEOPROTEIN COMPLEXES LOCATED AT THE DISTAL ENDS OF CHROMOSOMES. IN ADULTS, PROGRESSIVE TELOMERE SHORTENING OCCURS THROUGHOUT THE LIFETIME AND IS THOUGHT TO CONTRIBUTE TO PROGRESSIVE AGING, PHYSIOLOGICAL SENESCENCE, MULTIORGAN DYSFUNCTION, AND ULTIMATELY, DEATH. AS DISCUSSED IN THIS REVIEW, MULTIPLE LINES OF EVIDENCE PROVIDE SUPPORT FOR THE BIOLOGICAL PLAUSIBILITY THAT A TELOMERE-BASED CLOCK MECHANISM ALSO DETERMINES THE LENGTH OF GESTATION, LEADING TO THE ONSET OF LABOR (PARTURITION). AFTER TELOMERE EXPANSION AT THE BEGINNING OF PREGNANCY, THE TELOMERE LENGTHS IN THE GESTATIONAL TISSUES (IE, THE PLACENTA AND FETAL MEMBRANES) PROGRESSIVELY SHORTEN THROUGHOUT THE REMAINDER OF PREGNANCY. THE RATE OF TELOMERE SHORTENING CAN BE ACCELERATED BY CONDITIONS THAT AFFECT THE MOTHER AND RESULT IN OXIDATIVE STRESS. PRETERM BIRTHS IN THE UNITED STATES ARE ASSOCIATED WITH MULTIPLE RISK FACTORS THAT ARE LINKED WITH INCREASED OXIDATIVE STRESS. ANTIOXIDANT VITAMINS (IE, VITAMINS E AND C) MITIGATE THE EFFECTS OF OXIDATIVE STRESS AND DELAY OR PREVENT TELOMERE SHORTENING. CLINICAL TRIALS WITH VITAMINS E AND C AND WITH MULTIVITAMINS STARTED DURING THE PERICONCEPTION PERIOD HAVE BEEN ASSOCIATED WITH REDUCED RATES OF PRETERM BIRTHS. IN THE UNITED STATES, AFRICAN-AMERICAN WOMEN HAVE A 2-3-FOLD HIGHER RATE OF PRETERM BIRTH. AFRICAN-AMERICAN WOMEN HAVE MULTIPLE RISK FACTORS FOR PREMATURE BIRTH, ALL OF WHICH ARE DISTINCT AND POTENTIALLY ADDITIVE WITH REGARD TO EPIGENETIC TELOMERE SHORTENING. THE "WEATHERING EFFECT" IS THE HYPOTHESIS TO EXPLAIN THE INCREASED RATES OF CHRONIC ILLNESS, DISABILITIES, AND EARLY DEATH OBSERVED IN AFRICAN-AMERICANS. WITH REGARD TO PREGNANCY, ACCELERATED WEATHERING WITH THE ASSOCIATED TELOMERE SHORTENING IN THE GESTATIONAL TISSUES WOULD NOT ONLY EXPLAIN THE PRETERM BIRTH DISPARITY BUT COULD ALSO EXPLAIN WHY HIGHLY EDUCATED, AFFLUENT AFRICAN-AMERICAN WOMEN CONTINUE TO HAVE AN INCREASED RATE OF PRETERM BIRTH. THESE STUDIES SUGGEST THAT THE RACIAL DISPARITIES IN PRETERM BIRTH ARE POTENTIALLY MEDIATED BY TELOMERE SHORTENING PRODUCED BY LIFETIME OR EVEN GENERATIONAL EXPOSURE TO THE EFFECTS OF SYSTEMIC RACISM AND SOCIOECONOMIC MARGINALIZATION. IN CONCLUSION, THIS REVIEW PRESENTS MULTIPLE LINES OF EVIDENCE SUPPORTING A NOVEL HYPOTHESIS REGARDING THE BIOLOGICAL CLOCK MECHANISM THAT DETERMINES THE LENGTH OF PREGNANCY, AND IT OPENS THE POSSIBILITY OF NEW APPROACHES TO PREVENT OR REDUCE THE RATE OF SPONTANEOUS PRETERM BIRTH.	2022	
                                                                                                                                                                     
16    92  22 A PILOT STUDY INVESTIGATING THE ROLE OF GENDER IN THE INTERGENERATIONAL RELATIONSHIPS BETWEEN GENE EXPRESSION, CHRONIC PAIN, AND ADVERSE CHILDHOOD EXPERIENCES IN A CLINICAL SAMPLE OF YOUTH WITH CHRONIC PAIN. CHRONIC PAIN IS A HIGHLY PREVALENT AND COSTLY ISSUE THAT OFTEN EMERGES DURING CHILDHOOD OR ADOLESCENCE AND PERSISTS INTO ADULTHOOD. ADVERSE CHILDHOOD EXPERIENCES (ACES) INCREASE RISK FOR SEVERAL ADVERSE HEALTH CONDITIONS, INCLUDING CHRONIC PAIN. RECENT EVIDENCE SUGGESTS THAT PARENTAL TRAUMA (ACES, POST-TRAUMATIC STRESS DISORDER (PTSD) SYMPTOMS) CONFERS RISK OF POOR HEALTH OUTCOMES IN THEIR CHILDREN. INTERGENERATIONAL RELATIONSHIPS BETWEEN PARENTAL TRAUMA AND CHILD CHRONIC PAIN MAY BE MEDIATED BY EPIGENETIC MECHANISMS. A CLINICAL SAMPLE OF YOUTH WITH CHRONIC PAIN AND THEIR PARENTS COMPLETED PSYCHOMETRICALLY SOUND QUESTIONNAIRES ASSESSING ACES, PTSD SYMPTOMS, AND CHRONIC PAIN, AND PROVIDED A SALIVA SAMPLE. THESE WERE USED TO INVESTIGATE THE INTERGENERATIONAL RELATIONSHIPS BETWEEN FOUR EPIGENETIC BIOMARKERS (COMT, DRD2, GR, AND SERT), TRAUMA, AND CHRONIC PAIN. THE RESULTS INDICATED THAT THE SIGNIFICANT BIOMARKERS WERE DEPENDENT UPON THE GENDER OF THE CHILD, WHEREIN PARENTAL ACES SIGNIFICANTLY CORRELATED WITH CHANGES IN DRD2 EXPRESSION IN FEMALE CHILDREN AND ALTERED COMT EXPRESSION IN THE PARENTS OF MALE CHILDREN. ADDITIONALLY, THE NATURE OF THE ACE (MALTREATMENT VS. HOUSEHOLD DYSFUNCTION) WAS ASSOCIATED WITH THE SPECIFIC EPIGENETIC CHANGES. THERE MAY BE DIFFERENT PATHWAYS THROUGH WHICH PARENTAL ACES CONFER RISK FOR POOR OUTCOMES FOR MALES AND FEMALES, HIGHLIGHTING THE IMPORTANCE OF CHILD GENDER IN FUTURE INVESTIGATIONS.	2021	
                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                             
17  4622  18 NEUROBIOLOGICAL DEVELOPMENT IN THE CONTEXT OF CHILDHOOD TRAUMA. NEUROBIOLOGICAL SYSTEMS MAY BE PARTICULARLY SUSCEPTIBLE TO DELETERIOUS IMPACT OF CHILDHOOD TRAUMA, AND THE IMPACT OF CHILDHOOD TRAUMA ON DEVELOPMENT AND SUBSEQUENT FUNCTIONAL OUTCOMES ACROSS THE LIFESPAN HAS BEEN WELL-DOCUMENTED. THE CURRENT REVIEW ADDRESSES THE NEUROBIOLOGICAL IMPACT OF EXPOSURE TO INTERPERSONAL TRAUMA IN CHILDHOOD IN THE CONTEXT OF EXECUTIVE FUNCTION, EMOTION REGULATION, AND DISSOCIATION/INTEROCEPTIVE AWARENESS. SUBSEQUENT RISK FOR PTSD AND DEPRESSION IS ALSO DISCUSSED.

18  5787  32 SPUTUM ANALYSIS: NON-INVASIVE EARLY LUNG CANCER DETECTION. LUNG CANCER IS THE LEADING CAUSE OF CANCER-RELATED DEATHS OVER THE WORLD, CHARACTERIZED BY A VERY HIGH MORTALITY RATE. MOLECULAR TECHNIQUE DEVELOPMENT TRIES TO FOCUS ON EARLY DETECTION OF CANCERS BY STUDYING MOLECULAR ALTERATIONS THAT CHARACTERIZE CANCER CELLS. WORLDWIDE LUNG CANCER RESEARCH HAS FOCUSED ON AN EVER-INCREASING NUMBER OF MOLECULAR ELEMENTS OF CARCINOGENESIS AT GENETIC, EPIGENETIC AND PROTEIN LEVELS. THE NON-INVASIVENESS IS THE CHARACTERISTIC THAT ALL CLINICAL TRIALS ON CANCER DETECTION SHOULD HAVE. ABNORMAL CHEST IMAGING AND/OR NON-SPECIFIC SYMPTOMS ARE INITIAL SIGNALS OF LUNG CANCER THAT APPEAR IN AN ADVANCED STAGE OF DISEASE. THIS FACT REPRESENTS THE CAUSE OF THE LOW 5-YEAR SURVIVAL RATE: OVER 90% OF PATIENTS DYING WITHIN 5 YEARS OF DIAGNOSIS. SINCE SMOKERS HAVE HIGHER QUANTITY OF SPUTUM CONTAINING EXFOLIATED CELLS FROM THE BRONCHIAL TREE, AND THE SPUTUM REPRESENTS THE MOST EASILY ACCESSIBLE BIOLOGICAL FLUID AND ITS COLLECTION IS NON-INVASIVE, ANALYSIS OF THIS SAMPLE REPRESENTS A GOOD AREA OF RESEARCH IN EARLY LUNG CANCER DIAGNOSIS. CONTINUED CIGARETTE SMOKING IS THE CAUSE OF CHRONIC OBSTRUCTIVE PULMONARY DISEASE (COPD), WITH AN ESTIMATED ATTRIBUTABLE RISK FACTOR EXCEEDING 80% IN SMOKING AFFECTED INDIVIDUALS. LUNG CANCER IS FOUND IN 40-70% OF PATIENTS WITH COPD, PARTICULARLY IN SEVERE DISEASE, AND IT IS A COMMON CAUSE OF DEATH IN THESE PATIENTS. A LARGE PROSPECTIVE TRIAL OF ALMOST HALF A MILLION NON-SMOKERS SHOWED AS LUNG CANCER IS ALSO COMMON IN PATIENTS WITH COPD WHO HAVE NEVER SMOKED. THIS REVIEW DESCRIBES ISSUES RELATED TO EARLY LUNG CANCER SCREENING USING NON-INVASIVE METHODS.	2013	
                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                          
19  5338  38 QUANTITATIVE EVALUATION OF RASSF1A METHYLATION IN THE NON-LESIONAL, REGENERATIVE AND NEOPLASTIC LIVER. BACKGROUND: EPIGENETIC CHANGES DURING AGEING AND THEIR RELATIONSHIP WITH CANCER ARE UNDER THE FOCUS OF INTENSE RESEARCH. RASSF1A AND NORE1A ARE NOVEL GENES ACTING IN CONCERT IN THE PROAPOPTOTIC PATHWAY OF THE RAS SIGNALLING. WHILE NORE1A HAS NOT BEEN PREVIOUSLY INVESTIGATED IN THE HUMAN LIVER, RECENT REPORTS HAVE SUGGESTED THAT RASSF1A IS FREQUENTLY EPIGENETICALLY METHYLATED NOT ONLY IN HCC BUT ALSO IN THE CIRRHOTIC LIVER. METHODS: TO ADDRESS WHETHER EPIGENETIC CHANGES TAKE PLACE IN CONNECTION TO AGE AND/OR TO THE UNDERLYING DISEASE, WE INVESTIGATED RASSF1A AND NORE1A GENE PROMOTER METHYLATION BY CONVENTIONAL METHYLATION SPECIFIC PCR AND REAL-TIME MSP IN A SERIES OF HEPATITIC AND NON-HEPATITIC LIVERS HARBORING REGENERATIVE/HYPERPLASTIC (CIRRHOSIS/FOCAL NODULAR HYPERPLASIA), DYSPLASTIC (LARGE REGENERATIVE, LOW AND HIGH GRADE DYSPLASTIC NODULES) AND NEOPLASTIC (HEPATOCELLULAR ADENOMA AND CARCINOMA) GROWTHS. RESULTS: IN THE HEPATITIC LIVER (CHRONIC HEPATITIC/CIRRHOSIS, HEPATOCELLULAR NODULES AND HCC) WE FOUND WIDESPREAD RASSF1A GENE PROMOTER METHYLATION WITH A METHYLATION INDEX THAT INCREASED FROM REGENERATIVE CONDITIONS (CIRRHOSIS) TO HEPATOCELLULAR NODULES (P < 0.01) TO HCC (P < 0.001). IN THE NON-HEPATITIC LIVER A CONSISTENT PATTERN OF GENE METHYLATION WAS ALSO FOUND IN BOTH LESIONAL (FOCAL NODULAR HYPERPLASIA AND HEPATOCELLULAR ADENOMA) AND NON-LESIONAL TISSUE. SPECIFICALLY, HEPATOCELLULAR ADENOMAS (HA) SHOWED A METHYLATION INDEX SIGNIFICANTLY HIGHER THAN THAT DETECTED IN FOCAL NODULAR HYPERPLASIA (FNH) (P < 0.01) AND IN NON-LESIONAL TISSUE (P < 0.001). IN NON-LESIONAL LIVER ALSO THE METHYLATION INDEX GRADUALLY INCREASED BY AGEING (P = 0.002), SUGGESTING A PROGRESSIVE SPREADING OF METHYLATED CELLS OVER TIME. AS OPPOSED TO RASSF1A GENE PROMOTER METHYLATION, NORE1A GENE WAS NEVER FOUND EPIGENETICALLY ALTERATED IN BOTH HEPATITIC AND NON-HEPATITIC LIVER. CONCLUSION: WE HAVE SHOWN THAT IN NON-LESIONAL, REGENERATIVE AND NEOPLASTIC LIVER THE RASSF1A GENE IS INCREASINGLY METHYLATED, THAT THIS CONDITION TAKES PLACE AS AN AGE-RELATED PHENOMENON AND THAT THE EARLY SETTING AND SPREADING OVER TIME OF AN EPIGENETICALLY METHYLATED HEPATOCYTE SUBPOPULATION, MIGHT BE RELATED TO LIVER TUMORIGENESIS.	2006	
                                                                                                                                                                                                                                                                                                                                                                                                         
20  6278  28 THE PATHWAYS BETWEEN CORTISOL-RELATED REGULATION GENES AND PTSD PSYCHOTHERAPY. POST-TRAUMATIC STRESS DISORDER (PTSD) ONLY DEVELOPS AFTER EXPOSURE TO A TRAUMATIC EVENT IN SOME INDIVIDUALS. PTSD CAN BE CHRONIC AND DEBILITATING, AND IS ASSOCIATED WITH CO-MORBIDITIES SUCH AS DEPRESSION, SUBSTANCE USE, AND CARDIOMETABOLIC DISORDERS. ONE OF THE MOST IMPORTANT PATHOPHYSIOLOGICAL MECHANISMS UNDERLYING THE DEVELOPMENT OF PTSD AND ITS SUBSEQUENT MAINTENANCE IS A DYSFUNCTIONAL HYPOTHALAMIC-PITUITARY-ADRENAL (HPA) AXIS. THE CORTICOTROPHIN-RELEASING HORMONE, CORTISOL, GLUCOCORTICOID RECEPTOR (GR), AND THEIR RESPECTIVE GENES ARE SOME OF THE MEDIATORS OF PTSD'S PATHOPHYSIOLOGY. SEVERAL TREATMENTS ARE AVAILABLE, INCLUDING MEDICATION AND PSYCHOTHERAPIES, ALTHOUGH THEIR SUCCESS RATE IS LIMITED. SOME PHARMACOLOGICAL THERAPIES BASED ON THE HPA AXIS ARE CURRENTLY BEING TESTED IN CLINICAL TRIALS AND CHANGES IN HPA AXIS BIOMARKERS HAVE BEEN FOUND TO OCCUR IN RESPONSE NOT ONLY TO PHARMACOLOGICAL TREATMENTS, BUT ALSO TO PSYCHOTHERAPY-INCLUDING THE EPIGENETIC MODIFICATION OF THE GR GENE. PSYCHOTHERAPIES ARE CONSIDERED TO BE THE FIRST LINE TREATMENTS FOR PTSD IN SOME GUIDELINES, EVEN THOUGH THEY ARE EFFECTIVE FOR SOME, BUT NOT FOR ALL PATIENTS WITH PTSD. THIS REVIEW AIMS TO ADDRESS HOW KNOWLEDGE OF THE HPA AXIS-RELATED GENETIC MAKEUP CAN INFORM AND PREDICT THE OUTCOMES OF PSYCHOTHERAPEUTIC TREATMENTS.	2020
