1 1157 130 CONTAMINANT METALS AS CARDIOVASCULAR RISK FACTORS: A SCIENTIFIC STATEMENT FROM THE AMERICAN HEART ASSOCIATION. EXPOSURE TO ENVIRONMENTAL POLLUTANTS IS LINKED TO INCREASED RISK OF CARDIOVASCULAR DISEASE. BEYOND THE EXTENSIVE EVIDENCE FOR PARTICULATE AIR POLLUTION, ACCUMULATING EVIDENCE SUPPORTS THAT EXPOSURE TO NONESSENTIAL METALS SUCH AS LEAD, CADMIUM, AND ARSENIC IS A SIGNIFICANT CONTRIBUTOR TO CARDIOVASCULAR DISEASE WORLDWIDE. HUMANS ARE EXPOSED TO METALS THROUGH AIR, WATER, SOIL, AND FOOD AND EXTENSIVE INDUSTRIAL AND PUBLIC USE. CONTAMINANT METALS INTERFERE WITH CRITICAL INTRACELLULAR REACTIONS AND FUNCTIONS LEADING TO OXIDATIVE STRESS AND CHRONIC INFLAMMATION THAT RESULT IN ENDOTHELIAL DYSFUNCTION, HYPERTENSION, EPIGENETIC DYSREGULATION, DYSLIPIDEMIA, AND CHANGES IN MYOCARDIAL EXCITATION AND CONTRACTILE FUNCTION. LEAD, CADMIUM, AND ARSENIC HAVE BEEN LINKED TO SUBCLINICAL ATHEROSCLEROSIS, CORONARY ARTERY STENOSIS, AND CALCIFICATION AS WELL AS TO INCREASED RISK OF ISCHEMIC HEART DISEASE AND STROKE, LEFT VENTRICULAR HYPERTROPHY AND HEART FAILURE, AND PERIPHERAL ARTERY DISEASE. EPIDEMIOLOGICAL STUDIES SHOW THAT EXPOSURE TO LEAD, CADMIUM, OR ARSENIC IS ASSOCIATED WITH CARDIOVASCULAR DEATH MOSTLY ATTRIBUTABLE TO ISCHEMIC HEART DISEASE. PUBLIC HEALTH MEASURES REDUCING METAL EXPOSURE ARE ASSOCIATED WITH REDUCTIONS IN CARDIOVASCULAR DISEASE DEATH. POPULATIONS OF COLOR AND LOW SOCIOECONOMIC MEANS ARE MORE COMMONLY EXPOSED TO METALS AND THEREFORE AT GREATER RISK OF METAL-INDUCED CARDIOVASCULAR DISEASE. TOGETHER WITH STRENGTHENING PUBLIC HEALTH MEASURES TO PREVENT METAL EXPOSURES, DEVELOPMENT OF MORE SENSITIVE AND SELECTIVE MEASUREMENT MODALITIES, CLINICAL MONITORING OF METAL EXPOSURES, AND THE DEVELOPMENT OF METAL CHELATION THERAPIES COULD FURTHER DIMINISH THE BURDEN OF CARDIOVASCULAR DISEASE ATTRIBUTABLE TO METAL EXPOSURE.	2023	
                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                       
2 4881  40 OVERVIEW OF THE CARDIOVASCULAR EFFECTS OF ENVIRONMENTAL METALS: NEW PRECLINICAL AND CLINICAL INSIGHTS. ENVIRONMENTAL CAUSES OF CARDIOVASCULAR DISEASES (CVDS) ARE GLOBAL HEALTH ISSUES. IN PARTICULAR, AN ASSOCIATION BETWEEN METAL EXPOSURE AND CVDS HAS BECOME EVIDENT BUT CAUSAL EVIDENCE STILL LACKS. THEREFORE, THIS SYMPOSIUM AT THE SOCIETY OF TOXICOLOGY 2022 ANNUAL MEETING ADDRESSED EPIDEMIOLOGICAL, CLINICAL, PRE-CLINICAL ANIMAL MODEL-DERIVED AND MECHANISM-BASED EVIDENCE BY FIVE PRESENTATIONS: 1) AN EPIDEMIOLOGIC STUDY ON POTENTIAL CVD RISKS OF INDIVIDUALS EXPOSED OCCUPATIONALLY AND ENVIRONMENTALLY TO HEAVY METALS; 2) BOTH PRESENTATIONS OF THE SECOND AND THIRD WERE CLINICAL STUDIES FOCUSING ON THE POTENTIAL LINK BETWEEN HEAVY METALS AND PULMONARY ARTERIAL HYPERTENSION (PAH), BY PRESENTING ALTERED BLOOD METAL CONCENTRATIONS OF BOTH NON-ESSENTIAL AND ESSENTIAL METALS IN THE PATIENTS WITH PAH AND POTENTIAL THERAPEUTIC APPROACHES; 3) ARSENIC-INDUCED ATHEROSCLEROSIS VIA INFLAMMATORY CELLS IN MOUSE MODEL; 4) PATHOGENIC EFFECTS ON THE HEART BY ADULT CHRONIC EXPOSURE TO VERY LOW-DOSE CADMIUM VIA EPIGENETIC MECHANISMS AND WHOLE LIFE EXPOSURE TO LOW DOSE CADMIUM VIA EXACERBATING HIGH-FAT-DIET-LIPOTOXICITY. THIS SYMPOSIUM HAS BROUGHT EPIDEMIOLOGISTS, THERAPEUTIC INDUSTRY, PHYSICIANS, AND TRANSLATIONAL SCIENTISTS TOGETHER TO DISCUSS THE HEALTH RISKS OF OCCUPATIONAL AND ENVIRONMENTAL EXPOSURE TO HEAVY METALS THROUGH DIRECT CARDIOTOXICITY AND INDIRECT DISRUPTION OF HOMEOSTATIC MECHANISMS REGULATING ESSENTIAL METALS, AS WELL AS LIPID LEVELS. THE DATA SUMMARIZED BY THE PRESENTERS INFERS A POTENTIAL CAUSAL LINK BETWEEN MULTIPLE METALS AND CVDS AND DEFINES DIFFERENCES AND COMMONALITIES. THEREFORE, SUMMARY OF THESE PRESENTATIONS MAY ACCELERATE THE DEVELOPMENT OF EFFICIENT PREVENTIVE AND THERAPEUTIC STRATEGIES BY FACILITATING COLLABORATIONS AMONG MULTIDISCIPLINARY INVESTIGATORS.	2022	
                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                               
3 6781  51 [BREATHING: AMBIENT AIR POLLUTION AND HEALTH - PART III]. THE THIRD PART OF THE DGP STATEMENT INTRODUCES THE CURRENT BODY OF KNOWLEDGE ON LESS STUDIED HEALTH OUTCOMES ASSOCIATED WITH EXPOSURE TO AMBIENT AIR POLLUTION: THE NEGATIVE IMPACT ON METABOLISM LEADING TO IMPAIRED GLUCOSE TOLERANCE AND DIABETES AS WELL AS CONTRIBUTION TO THE DEVELOPMENT OF NEURODEGENERATIVE DISORDERS AND DELAYED COGNITIVE FUNCTION IN CHILDREN. FURTHERMORE, PRENATAL EXPOSURE AND ADVERSE EFFECTS ON MOTHER AND CHILD ARE ADDRESSED. FINALLY, THE CURRENTLY DISCUSSED BIOLOGICAL MECHANISMS UNDERLYING VARIOUS HEALTH EFFECTS ASSOCIATED WITH EXPOSURE TO AIR POLLUTION ARE DESCRIBED.DIFFERING, BUT OFTEN COMPLEMENTARY BIOLOGICAL MECHANISMS CREATE THE BASIS FOR THE DIVERSE HEALTH OUTCOMES CAUSED BY AIR POLLUTION. OXIDATIVE STRESS AND A SUBCLINICAL INFLAMMATORY RESPONSE IN THE LUNGS AND ON A SYSTEMIC LEVEL ("LOW-GRADE SYSTEMIC INFLAMMATION") ARE CONSIDERED TO BE KEY MECHANISMS. THEY PROMOTE SECONDARY ALTERATIONS IN THE BODY, SUCH AS VASCULAR OR METABOLIC PROCESSES, AND MAY ALSO RESULT IN THE CURRENTLY STUDIED EPIGENETIC PHENOMENA OR NEUROINFLAMMATION. IN THIS CONTEXT, THE HEALTH SIGNIFICANCE OF SOLUBLE PARTICULATE MATTER AND THE ROLE OF ULTRAFINE PARTICLES TRANSLOCATED ACROSS BIOLOGICAL MEMBRANES INTO BLOOD VESSEL AND TRANSPORTED VIA THE CIRCULATION TO SECONDARY TARGET ORGANS, SUCH AS LIVER, BRAIN OR THE FETUS, ARE INTENSIVELY DISCUSSED.DIABETES IS ONE OF THE LEADING CHRONIC DISEASES WORLDWIDE, WITH A PREVALENCE OF ALMOST 14 % IN GERMANY. ALTHOUGH LIFESTYLE FACTORS ARE THE MAIN CAUSES, CURRENT EVIDENCE SUGGESTS THAT LONG-TERM EXPOSURE TO AIR POLLUTION MAY ADDITIONALLY INCREASE THE RISK FOR TYPE 2 DIABETES. SUPPORTING EVIDENCE FOR A CAUSAL ROLE OF AIR POLLUTION IS PROVIDED BY STUDIES ADDRESSING THE REGULATION OF THE BLOOD GLUCOSE LEVELS IN METABOLICALLY HEALTHY PARTICIPANTS, INSULIN SENSITIVITY, OR PREGNANCY-RELATED DIABETES. EXPERIMENTAL STUDIES PROVIDE FURTHER SUPPORT FOR PLAUSIBLE BIOLOGICAL MECHANISMS. HOWEVER, PROSPECTIVE STUDIES ARE NEEDED TO GAIN MORE EVIDENCE, TAKING MULTIPLE LIFESTYLE AND ENVIRONMENTAL FACTORS, SUCH AS GREEN SPACE AND NOISE, AND AN IMPROVED INDIVIDUAL EXPOSURE ASSESSMENT INTO ACCOUNT.THE AGING POPULATION HAS AN INCREASED RISK OF NEURODEGENERATIVE DISEASES. FIRST STUDIES POINT TOWARDS A CONTRIBUTION OF CHRONIC EXPOSURE TO AIR POLLUTION, SPECIFICALLY BY PARTICULATE MATTER. SEVERAL STUDIES REPORT ITS ASSOCIATION WITH DECREASED NEUROCOGNITIVE CAPACITY OR AN INCREASED PREVALENCE OF DEMENTIA OR ALZHEIMER'S DISEASE IN ADULTS. HOWEVER, THE STUDIES ARE INHOMOGENEOUS REGARDING DESIGN, EXPOSURE AND OUTCOME, LEADING TO INCONSISTENT RESULTS. WITH RESPECT TO THE INFLUENCE ON NEUROCOGNITIVE DEVELOPMENT OF CHILDREN, FIRST STUDIES SUGGEST AN ASSOCIATION BETWEEN THE LEVEL OF AIR POLLUTION, E. G. AT SCHOOL, AND DELAYED COGNITIVE DEVELOPMENT.EVEN THOUGH THE EVIDENCE FOR THE DIFFERENT BIOLOGICAL ENDPOINTS DURING PREGNANCY IS STILL HETEROGENEOUS, THE STUDIES GENERALLY POINT TOWARDS AN ADVERSE IMPACT OF AIR POLLUTION ON THE MATERNAL AND FETAL ORGANISMS. THE STRONGEST EVIDENCE EXISTS FOR LOW BIRTH WEIGHT, WITH SMALL EFFECT SIZES OF ONLY SOME GRAMS, AND FOR A HIGHER INCIDENCE OF REDUCED BIRTH WEIGHT (< 2500 G). AN INCREASED RISK FOR GESTATIONAL HYPERTENSION AND PREECLAMPSIA UNDERSCORES THE POSSIBLE IMPACT OF EXPOSURE TO AIR POLLUTION ON THE MATERNAL ORGANISM. HOWEVER, THE CURRENT BODY OF EVIDENCE DOES NOT YET ALLOW A FINAL CONCLUSION ON THE INFLUENCE OF INTRAUTERINE EXPOSURE TO AIR POLLUTION REGARDING EARLY CHILDHOOD LUNG FUNCTION AND DEVELOPMENT OF ALLERGIES, PARTICULARLY IN LIGHT OF THE FACT THAT IT IS HARD TO DISTINGUISH IN EPIDEMIOLOGICAL STUDIES BETWEEN THE EFFECTS OF PRE- AND POSTNATAL EXPOSURE.	2019	

4 2849  33 FROM AIR POLLUTION TO CARDIOVASCULAR DISEASES: THE EMERGING ROLE OF EPIGENETICS. THE ASSOCIATION BETWEEN AIR POLLUTION AND A WIDE-RANGING SPECTRUM OF ACUTE AND CHRONIC DISORDERS-INCLUDING CARDIOVASCULAR DISEASES-IS WIDELY ACKNOWLEDGED. EXPOSURE TO AIRBORNE POLLUTANTS TRIGGERS HARMFUL MECHANISMS SUCH AS OXIDATIVE STRESS AND SYSTEMIC INFLAMMATION, WHICH LEAD TO INCREASED INCIDENCE OF MYOCARDIAL INFARCTION, ARTERIAL HYPERTENSION, STROKE, AND HEART FAILURE. SUSTAINED EFFORTS HAVE BEEN MADE IN RECENT YEARS TO DISCOVER HOW ENVIRONMENTAL EXPOSURES AFFECT HUMAN HEALTH THROUGH EPIGENETIC PHENOMENA, SUCH AS DNA METHYLATION, HISTONE MODIFICATIONS AND NON-CODING RNA-MEDIATED GENE REGULATION. THIS REVIEW SUMMARIZES THE CURRENT EVIDENCES ON THE RELATIONSHIP BETWEEN AIR POLLUTION EXPOSURE, EPIGENETIC ALTERATIONS AND CARDIOVASCULAR IMPACT, IN VIEW OF PRESENT IMPLICATIONS AND FUTURE PERSPECTIVES.	2020	
                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                   
5 1932  32 ENVIRONMENTAL EXPOSURES: AN UNDERRECOGNIZED CONTRIBUTION TO NONCOMMUNICABLE DISEASES. PREVIOUS ATTEMPTS TO DETERMINE THE DEGREE TO WHICH EXPOSURE TO ENVIRONMENTAL FACTORS CONTRIBUTE TO NONCOMMUNICABLE DISEASES (NCDS) HAVE BEEN VERY CONSERVATIVE AND HAVE SIGNIFICANTLY UNDERESTIMATED THE ACTUAL CONTRIBUTION OF THE ENVIRONMENT FOR AT LEAST TWO REASONS. FIRSTLY, MOST PREVIOUS REPORTS HAVE EXCLUDED THE CONTRIBUTION OF LIFESTYLE BEHAVIORAL RISK FACTORS, BUT THESE USUALLY INVOLVE SIGNIFICANT EXPOSURE TO ENVIRONMENTAL CHEMICALS THAT INCREASE RISK OF DISEASE. SECONDLY, EARLY LIFE EXPOSURE TO CHEMICAL CONTAMINANTS IS NOW CLEARLY ASSOCIATED WITH AN ELEVATED RISK OF SEVERAL DISEASES LATER IN LIFE, BUT THESE CONNECTIONS ARE OFTEN DIFFICULT TO DISCERN. THIS IS ESPECIALLY TRUE FOR ASTHMA AND NEURODEVELOPMENTAL CONDITIONS, BUT THERE IS ALSO A MAJOR CONTRIBUTION TO THE DEVELOPMENT OF OBESITY AND CHRONIC DISEASES. MOST CANCERS ARE CAUSED BY ENVIRONMENTAL EXPOSURES IN GENETICALLY SUSCEPTIBLE INDIVIDUALS. IN ADDITION, NEW INFORMATION SHOWS SIGNIFICANT ASSOCIATIONS BETWEEN CARDIOVASCULAR DISEASES AND DIABETES AND EXPOSURE TO ENVIRONMENTAL CHEMICALS PRESENT IN AIR, FOOD, AND WATER. THESE RELATIONSHIPS LIKELY REFLECT THE COMBINATION OF EPIGENETIC EFFECTS AND GENE INDUCTION. ENVIRONMENTAL FACTORS CONTRIBUTE SIGNIFICANTLY MORE TO NCDS THAN PREVIOUS REPORTS HAVE SUGGESTED. PREVENTION NEEDS TO SHIFT FOCUS FROM INDIVIDUAL RESPONSIBILITY TO SOCIETAL RESPONSIBILITY AND AN UNDERSTANDING THAT EFFECTIVE PREVENTION OF NCDS ULTIMATELY RELIES ON IMPROVED ENVIRONMENTAL MANAGEMENT TO REDUCE EXPOSURE TO MODIFIABLE RISKS.	2013	
                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                      
6  754  39 CARDIOVASCULAR ADAPTATIONS TO PARTICLE INHALATION EXPOSURE: MOLECULAR MECHANISMS OF THE TOXICOLOGY. AMBIENT AIR, OCCUPATIONAL SETTINGS, AND THE USE AND DISTRIBUTION OF CONSUMER PRODUCTS ALL SERVE AS CONDUITS FOR TOXICANT EXPOSURE THROUGH INHALATION. WHILE THE PULMONARY SYSTEM REMAINS A PRIMARY TARGET FOLLOWING INHALATION EXPOSURE, CARDIOVASCULAR IMPLICATIONS ARE EXCEPTIONALLY CULPABLE FOR INCREASED MORBIDITY AND MORTALITY. THE EPIDEMIOLOGICAL EVIDENCE FOR CARDIOVASCULAR DYSFUNCTION RESULTING FROM ACUTE OR CHRONIC INHALATION EXPOSURE TO PARTICULATE MATTER HAS BEEN WELL DOCUMENTED, BUT THE MECHANISMS DRIVING THE RESULTING DISTURBANCES REMAIN ELUSIVE. IN THE CURRENT REVIEW, WE AIM TO SUMMARIZE THE CELLULAR AND MOLECULAR MECHANISMS THAT ARE DIRECTLY LINKED TO CARDIOVASCULAR HEALTH FOLLOWING EXPOSURE TO A VARIETY OF INHALED TOXICANTS. THE PURPOSE OF THIS REVIEW IS TO PROVIDE A COMPREHENSIVE OVERVIEW OF THE BIOCHEMICAL CHANGES IN THE CARDIOVASCULAR SYSTEM FOLLOWING PARTICLE INHALATION EXPOSURE AND TO HIGHLIGHT POTENTIAL BIOMARKERS THAT EXIST ACROSS MULTIPLE EXPOSURE PARADIGMS. WE ATTEMPT TO INTEGRATE THESE MOLECULAR SIGNATURES IN AN EFFORT TO PROVIDE DIRECTION FOR FUTURE INVESTIGATIONS. THIS REVIEW ALSO CHARACTERIZES HOW MOLECULAR RESPONSES ARE MODIFIED IN AT-RISK POPULATIONS, SPECIFICALLY THE IMPACT OF ENVIRONMENTAL EXPOSURE DURING CRITICAL WINDOWS OF DEVELOPMENT. MATERNAL EXPOSURE TO PARTICULATE MATTER DURING GESTATION CAN LEAD TO FETAL EPIGENETIC REPROGRAMMING, RESULTING IN LONG-TERM DEFICITS TO THE CARDIOVASCULAR SYSTEM. IN BOTH DIRECT AND INDIRECT (GESTATIONAL) EXPOSURES, CONNECTING THE BIOCHEMICAL MECHANISMS WITH FUNCTIONAL DEFICITS OUTLINES PATHWAYS THAT CAN BE TARGETED FOR FUTURE THERAPEUTIC INTERVENTION. ULTIMATELY, FUTURE INVESTIGATIONS INTEGRATING "OMICS"-BASED APPROACHES WILL BETTER ELUCIDATE THE MECHANISMS THAT ARE ALTERED BY XENOBIOTIC INHALATION EXPOSURE, IDENTIFY BIOMARKERS, AND GUIDE IN CLINICAL DECISION MAKING.	2020	
                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                           
7 1919  36 ENVIRONMENTAL ENDOCRINE DISRUPTORS: NEW DIABETOGENS? THE PREVALENCE OF TYPE-2 DIABETES HAS DRAMATICALLY INCREASED WORLDWIDE DURING THE LAST FEW DECADES. WHILE LIFESTYLE FACTORS (SEDENTARINESS, NOXIOUS FOOD), TOGETHER WITH GENETIC SUSCEPTIBILITY, ARE WELL-KNOWN ACTORS, THERE IS ACCUMULATING EVIDENCE SUGGESTING THAT ENDOCRINE DISRUPTING CHEMICALS (EDCS) MAY ALSO PLAY A PATHOPHYSIOLOGICAL ROLE IN THE OCCURRENCE OF METABOLIC DISEASES. BOTH EXPERIMENTAL AND EPIDEMIOLOGICAL EVIDENCE SUPPORT A ROLE FOR EARLY AND CHRONIC EXPOSURE TO LOW DOSES OF CHEMICAL POLLUTANTS WITH ENDOCRINE AND METABOLIC DISRUPTING EFFECTS. MOST ARE PRESENT IN THE FOOD CHAIN AND ACCUMULATE IN THE FAT MASS AFTER ABSORPTION.

8 4626  33 NEURODEVELOPMENTAL DISORDERS AND ENVIRONMENTAL TOXICANTS: EPIGENETICS AS AN UNDERLYING MECHANISM. THE INCREASING PREVALENCE OF NEURODEVELOPMENTAL DISORDERS, ESPECIALLY AUTISM SPECTRUM DISORDERS (ASD) AND ATTENTION DEFICIT HYPERACTIVITY DISORDER (ADHD), CALLS FOR MORE RESEARCH INTO THE IDENTIFICATION OF ETIOLOGIC AND RISK FACTORS. THE DEVELOPMENTAL ORIGIN OF HEALTH AND DISEASE (DOHAD) HYPOTHESIZES THAT THE ENVIRONMENT DURING FETAL AND CHILDHOOD DEVELOPMENT AFFECTS THE RISK FOR MANY CHRONIC DISEASES IN LATER STAGES OF LIFE, INCLUDING NEURODEVELOPMENTAL DISORDERS. EPIGENETICS, A TERM DESCRIBING MECHANISMS THAT CAUSE CHANGES IN THE CHROMOSOME STATE WITHOUT AFFECTING DNA SEQUENCES, IS SUGGESTED TO BE THE UNDERLYING MECHANISM, ACCORDING TO THE DOHAD HYPOTHESIS. MOREOVER, MANY NEURODEVELOPMENTAL DISORDERS ARE ALSO RELATED TO EPIGENETIC ABNORMALITIES. EXPERIMENTAL AND EPIDEMIOLOGICAL STUDIES SUGGEST THAT EXPOSURE TO PRENATAL ENVIRONMENTAL TOXICANTS IS ASSOCIATED WITH NEURODEVELOPMENTAL DISORDERS. IN ADDITION, THERE IS ALSO EVIDENCE THAT ENVIRONMENTAL TOXICANTS CAN RESULT IN EPIGENETIC ALTERATIONS, NOTABLY DNA METHYLATION. IN THIS REVIEW, WE FIRST FOCUS ON THE RELATIONSHIP BETWEEN NEURODEVELOPMENTAL DISORDERS AND ENVIRONMENTAL TOXICANTS, IN PARTICULAR MATERNAL SMOKING, PLASTIC-DERIVED CHEMICALS (BISPHENOL A AND PHTHALATES), PERSISTENT ORGANIC POLLUTANTS, AND HEAVY METALS. WE THEN REVIEW STUDIES SHOWING THE EPIGENETIC EFFECTS OF THOSE ENVIRONMENTAL FACTORS IN HUMANS THAT MAY AFFECT NORMAL NEURODEVELOPMENT.	2017	
                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                              
9 4805  31 OBESITY AND METABOLIC COMORBIDITIES: ENVIRONMENTAL DISEASES? OBESITY AND METABOLIC COMORBIDITIES REPRESENT INCREASING HEALTH PROBLEMS. ENDOCRINE DISRUPTING COMPOUNDS (EDCS) ARE EXOGENOUS AGENTS THAT CHANGE ENDOCRINE FUNCTION AND CAUSE ADVERSE HEALTH EFFECTS. MOST EDCS ARE SYNTHETIC CHEMICALS; SOME ARE NATURAL FOOD COMPONENTS AS PHYTOESTROGENS. PEOPLE ARE EXPOSED TO COMPLEX MIXTURES OF CHEMICALS THROUGHOUT THEIR LIVES. EDCS IMPACT HORMONE-DEPENDENT METABOLIC SYSTEMS AND BRAIN FUNCTION. LABORATORY AND HUMAN STUDIES PROVIDE COMPELLING EVIDENCE THAT HUMAN CHEMICAL CONTAMINATION CAN PLAY A ROLE IN OBESITY EPIDEMIC. CHEMICAL EXPOSURES MAY INCREASE THE RISK OF OBESITY BY ALTERING THE DIFFERENTIATION OF ADIPOCYTES. EDCS CAN ALTER METHYLATION PATTERNS AND NORMAL EPIGENETIC PROGRAMMING IN CELLS. OXIDATIVE STRESS MAY BE INDUCED BY MANY OF THESE CHEMICALS, AND ACCUMULATING EVIDENCE INDICATES THAT IT PLAYS IMPORTANT ROLES IN THE ETIOLOGY OF CHRONIC DISEASES. THE INDIVIDUAL SENSITIVITY TO CHEMICALS IS VARIABLE, DEPENDING ON ENVIRONMENT AND ABILITY TO METABOLIZE HAZARDOUS CHEMICALS. A NUMBER OF GENES, ESPECIALLY THOSE REPRESENTING ANTIOXIDANT AND DETOXIFICATION PATHWAYS, HAVE POTENTIAL APPLICATION AS BIOMARKERS OF RISK ASSESSMENT. THE POTENTIAL HEALTH EFFECTS OF COMBINED EXPOSURES MAKE THE RISK ASSESSMENT PROCESS MORE COMPLEX COMPARED TO THE ASSESSMENT OF SINGLE CHEMICALS. TECHNIQUES AND METHODS NEED TO BE FURTHER DEVELOPED TO FILL DATA GAPS AND INCREASE THE KNOWLEDGE ON HARMFUL EXPOSURE COMBINATIONS.	2013	
                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                        
10 3775  31 INTERACTIONS BETWEEN ARSENIC-INDUCED TOXICITY AND NUTRITION IN EARLY LIFE. EXPOSURE TO ARSENIC THROUGH DRINKING WATER IS A MAJOR PUBLIC HEALTH PROBLEM AFFECTING MOST COUNTRIES, ALTHOUGH THE SITUATION IS PARTICULARLY SEVERE IN LOW-INCOME NATIONS. THE HEALTH CONSEQUENCES OF CHRONIC ARSENIC EXPOSURE INCLUDE INCREASED RISK FOR VARIOUS FORMS OF CANCER AND NUMEROUS NONCANCER EFFECTS, INCLUDING DIABETES, SKIN DISEASES, CHRONIC COUGH, AND TOXIC EFFECTS ON LIVER, KIDNEY, CARDIOVASCULAR SYSTEM, AND PERIPHERAL AND CENTRAL NERVOUS SYSTEMS. IN RECENT YEARS INCREASING REPORTS OF EFFECTS ON FETAL AND CHILD DEVELOPMENT HAVE APPEARED. THERE SEEMS TO BE A WIDE VARIATION IN SUSCEPTIBILITY TO ARSENIC TOXICITY, WHICH IS LIKELY TO BE RELATED TO FACTORS SUCH AS VARIATION IN ARSENIC METABOLISM, NUTRITION, HOST-RELATED DEFENSE MECHANISMS, AND GENETIC PREDISPOSITION. THE MAIN MECHANISMS OF ARSENIC-NUTRITION INTERACTIONS INCLUDE ARSENIC-INDUCED OXIDATIVE STRESS, WHICH REQUIRES NUTRIENT-DEPENDENT DEFENSE SYSTEMS, AND ARSENIC METABOLISM (METHYLATION) VIA 1-CARBON METABOLISM, WHICH REQUIRES METHYL GROUPS, FOLIC ACID, VITAMIN B-12, AND BETAINE FOR THE REMETHYLATION OF HOMOCYSTEINE TO METHIONINE. AN EFFICIENT FIRST METHYLATION STEP IN COMBINATION WITH A SLOW SECOND METHYLATION STEP SEEMS TO BE MOST CRITICAL FROM A TOXICOLOGICAL POINT OF VIEW. A THIRD MODE OF ARSENIC-NUTRITION INTERACTION INVOLVES EPIGENETIC EFFECTS AND FETAL PROGRAMMING VIA DNA METHYLATION.	2007	
                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                     
11 1324  33 DEOXYRIBONUCLEIC ACID (DNA) METHYLATION IN CHILDREN EXPOSED TO AIR POLLUTION: A POSSIBLE MECHANISM UNDERLYING RESPIRATORY HEALTH EFFECTS DEVELOPMENT. AIR POLLUTION IS A SUBSTANTIAL ENVIRONMENTAL THREAT TO CHILDREN AND ACTS AS ACUTE AND CHRONIC DISEASE RISK FACTORS ALIKE. SEVERAL STUDIES HAVE PREVIOUSLY EVALUATED EPIGENETIC MODIFICATIONS CONCERNING ITS EXPOSURE ACROSS VARIOUS LIFE STAGES. HOWEVER, FINDINGS ON EPIGENETIC MODIFICATIONS AS THE CONSEQUENCES OF AIR POLLUTION DURING CHILDHOOD ARE RATHER MINIMAL. THIS REVIEW EVALUATED HIGHLY RELEVANT STUDIES IN THE FIELD TO ANALYZE THE EXISTING LITERATURE REGARDING EXPOSURE TO AIR POLLUTION, WITH A FOCUS ON EPIGENETIC ALTERATIONS DURING CHILDHOOD AND THEIR CONNECTIONS WITH RESPIRATORY HEALTH EFFECTS. THE SEARCH WAS CONDUCTED USING READILY AVAILABLE ELECTRONIC DATABASES (PUBMED AND SCIENCEDIRECT) TO SCREEN FOR CHILDREN'S STUDIES ON EPIGENETIC MECHANISMS FOLLOWING EITHER PRE- OR POST-NATAL EXPOSURE TO AIR POLLUTANTS. STUDIES RELEVANT ENOUGH AND MATCHED THE PREDETERMINED CRITERIA WERE CHOSEN TO BE REVIEWED. NON-ENGLISH ARTICLES AND STUDIES THAT DID NOT REPORT BOTH AIR MONITORING AND EPIGENETIC OUTCOMES IN THE SAME ARTICLE WERE EXCLUDED. THE REVIEW FOUND THAT EPIGENETIC CHANGES HAVE BEEN LINKED WITH EXPOSURE TO AIR POLLUTANTS DURING EARLY LIFE WITH EVIDENCE AND REPORTS OF HOW THEY MAY DEREGULATE THE EPIGENOME BALANCE, THUS INDUCING DISEASE PROGRESSION IN THE FUTURE. EPIGENETIC STUDIES EVOLVE AS A PROMISING NEW APPROACH IN DECIPHERING THE UNDERLYING IMPACTS OF AIR POLLUTION ON DEOXYRIBONUCLEIC ACID (DNA) DUE TO LINKS ESTABLISHED BETWEEN SOME OF THESE EPIGENETIC MECHANISMS AND ILLNESSES.	2021	
                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                           
12 3566  33 IMPACT OF HEAVY METALS ON THE FEMALE REPRODUCTIVE SYSTEM. INTRODUCTION: IT HAS BEEN RECOGNIZED THAT ENVIRONMENTAL POLLUTION CAN AFFECT THE QUALITY OF HEALTH OF THE HUMAN POPULATION. HEAVY METALS ARE AMONG THE GROUP OF HIGHLY EMITTED CONTAMINANTS AND THEIR ADVERSE EFFECT OF LIVING ORGANISMS HAS BEEN WIDELY STUDIED IN RECENT DECADES. LIFESTYLE AND QUALITY OF THE AMBIENT ENVIRONMENT ARE AMONG THESE FACTORS WHICH CAN MAINLY CONTRIBUTE TO THE HEAVY METALS EXPOSURE IN HUMANS. OBJECTIVE: A REVIEW OF LITERATURE LINKING HEAVY METALS AND THE FEMALE REPRODUCTIVE SYSTEM AND DESCRIPTION OF THE POSSIBLE ASSOCIATIONS WITH EMISSION AND EXPOSURE OF HEAVY METALS AND IMPAIRMENTS OF FEMALE REPRODUCTIVE SYSTEM ACCORDING TO CURRENT KNOWLEDGE. RESULTS: THE POTENTIAL HEALTH DISORDERS CAUSED BY CHRONIC OR ACUTE HEAVY METALS TOXICITY INCLUDE IMMUNODEFICIENCY, OSTEOPOROSIS, NEURODEGENERATION AND ORGAN FAILURES. POTENTIAL LINKAGES OF HEAVY METALS CONCENTRATION FOUND IN DIFFERENT HUMAN ORGANS AND BLOOD WITH OESTROGEN-DEPENDENT DISEASES SUCH AS BREAST CANCER, ENDOMETRIAL CANCER, ENDOMETRIOSIS AND SPONTANEOUS ABORTIONS, AS WELL AS PRE-TERM DELIVERIES, STILLBIRTHS AND HYPOTROPHY, HAVE ALSO BEEN REPORTED. CONCLUSIONS: ENVIRONMENTAL DETERIORATION CAN LEAD TO THE ELEVATED RISK OF HUMAN EXPOSURE TO HEAVY METALS, AND CONSEQUENTLY, HEALTH IMPLICATIONS INCLUDING DISTURBANCES IN REPRODUCTION. IT IS THEREFORE IMPORTANT TO CONTINUE THE INVESTIGATIONS ON METAL-INDUCED MECHANISMS OF FERTILITY IMPAIRMENT ON THE GENETIC, EPIGENETIC AND BIOCHEMICAL LEVEL.	2015	
                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                
13  633  33 BIOLOGICAL EFFECTS AND EPIDEMIOLOGICAL CONSEQUENCES OF ARSENIC EXPOSURE, AND REAGENTS THAT CAN AMELIORATE ARSENIC DAMAGE IN VIVO. THROUGH CONTAMINATED DIET, WATER, AND OTHER FORMS OF ENVIRONMENTAL EXPOSURE, ARSENIC AFFECTS HUMAN HEALTH. THERE ARE MANY U.S. AND WORLDWIDE "HOT SPOTS" WHERE THE ARSENIC LEVEL IN PUBLIC WATER EXCEEDS THE MAXIMUM EXPOSURE LIMIT. THE BIOLOGICAL EFFECTS OF CHRONIC ARSENIC EXPOSURE INCLUDE GENERATION OF REACTIVE OXYGEN SPECIES (ROS), LEADING TO OXIDATIVE STRESS AND DNA DAMAGE, EPIGENETIC DNA MODIFICATION, INDUCTION OF GENOMIC INSTABILITY, AND INFLAMMATION AND IMMUNOMODULATION, ALL OF WHICH CAN INITIATE CARCINOGENESIS. HIGH ARSENIC EXPOSURE IS EPIDEMIOLOGICALLY ASSOCIATED WITH SKIN, LUNG, BLADDER, LIVER, KIDNEY AND PANCREATIC CANCER, AND CARDIOVASCULAR, NEURONAL, AND OTHER DISEASES. THIS REVIEW BRIEFLY SUMMARIZES THE BIOLOGICAL EFFECTS OF ARSENIC EXPOSURE AND EPIDEMIOLOGICAL CANCER STUDIES WORLDWIDE, AND PROVIDES AN OVERVIEW FOR EMERGING RODENT-BASED STUDIES OF REAGENTS THAT CAN AMELIORATE THE EFFECTS OF ARSENIC EXPOSURE IN VIVO.

14 5434  25 RELATIONSHIP BETWEEN ENVIRONMENTAL EXPOSURES IN CHILDREN AND ADULT LUNG DISEASE: THE CASE FOR OUTDOOR EXPOSURES. THERE IS A GROWING UNDERSTANDING THAT CHRONIC RESPIRATORY DISEASES IN ADULTS HAVE THEIR ORIGINS IN EARLY LIFE. ADVERSE ENVIRONMENTAL EXPOSURES OCCURRING IN VULNERABLE PERIODS DURING LUNG GROWTH AND DEVELOPMENT IN THE FETAL PERIOD AND IN EARLY CHILDHOOD THAT ALTER LUNG STRUCTURE AND LIMIT THE GROWTH IN LUNG FUNCTION MAY HAVE LIFELONG CONSEQUENCES. EVIDENCE IS INCREASING THAT EXPOSURE TO THE AMBIENT ENVIRONMENT, INCLUDING AIR POLLUTANTS, PERSISTENT TOXIC SUBSTANCES, WATER POLLUTANTS AND RESPIRATORY VIRAL INFECTIONS, CAN INHIBIT LUNG FUNCTION GROWTH AND PREDISPOSE TO CHRONIC NON-MALIGNANT LUNG DISEASES. THESE EXPOSURES GENERALLY INTERACT WITH A GENETIC PREDISPOSITION, AND GENE-ENVIRONMENT INTERACTIONS AND EPIGENETIC PHENOMENA ARE ATTRACTING CONSIDERABLE STUDY. AN UNDERSTANDING OF HOW AMBIENT EXPOSURES IMPACT ON NORMAL LUNG GROWTH AND DEVELOPMENT WILL AID IN UNDERSTANDING OF HOW CHRONIC RESPIRATORY DISEASES OF ADULTS DEVELOP AND MAY LEAD TO NEW PREVENTATIVE STRATEGIES.	2010	
                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                          
15 3210  32 HEALTH EFFECTS ASSOCIATED WITH PRE- AND PERINATAL EXPOSURE TO ARSENIC. INORGANIC ARSENIC IS A WELL-ESTABLISHED HUMAN CARCINOGEN, ABLE TO INDUCE GENETIC AND EPIGENETIC ALTERATIONS. MORE THAN 200 MILLION PEOPLE WORLDWIDE ARE EXPOSED TO ARSENIC CONCENTRATIONS IN DRINKING WATER EXCEEDING THE RECOMMENDED WHO THRESHOLD (10MUG/L). ADDITIONALLY, CHRONIC EXPOSURE TO LEVELS BELOW THIS THRESHOLD IS KNOWN TO RESULT IN LONG-TERM HEALTH EFFECTS IN HUMANS. THE ARSENIC-RELATED HEALTH EFFECTS IN HUMANS ARE ASSOCIATED WITH ITS BIOTRANSFORMATION PROCESS, WHEREBY THE RESULTING METABOLITES CAN INDUCE MOLECULAR DAMAGE THAT ACCUMULATES OVER TIME. THE EFFECTS DERIVED FROM THESE ALTERATIONS INCLUDE GENOMIC INSTABILITY ASSOCIATED WITH OXIDATIVE DAMAGE, ALTERATION OF GENE EXPRESSION (INCLUDING CODING AND NON-CODING RNAS), GLOBAL AND LOCALIZED EPIGENETIC REPROGRAMMING, AND HISTONE POSTTRANSLATIONAL MODIFICATIONS. THESE ALTERATIONS DIRECTLY AFFECT MOLECULAR PATHWAYS INVOLVED IN THE ONSET AND PROGRESSION OF MANY CONDITIONS THAT CAN ARISE EVEN DECADES AFTER THE EXPOSURE OCCURS. IMPORTANTLY, ARSENIC METABOLITES GENERATED DURING ITS BIOTRANSFORMATION CAN ALSO PASS THROUGH THE PLACENTAL BARRIER, RESULTING IN FETAL EXPOSURE TO THIS CARCINOGEN AT SIMILAR LEVELS TO THOSE OF THE MOTHER. AS SUCH, MORE IMMEDIATE EFFECTS OF THE ARSENIC-INDUCED MOLECULAR DAMAGE CAN BE OBSERVED AS DETRIMENTAL EFFECTS ON FETAL DEVELOPMENT, PREGNANCY, AND BIRTH OUTCOMES. IN THIS REVIEW, WE FOCUS ON THE GENETIC AND EPIGENETIC DAMAGE ASSOCIATED WITH EXPOSURE TO LOW LEVELS OF ARSENIC, PARTICULARLY THOSE AFFECTING EARLY DEVELOPMENTAL STAGES. WE ALSO PRESENT HOW THESE ALTERATIONS OCCURRING DURING EARLY LIFE CAN IMPACT THE DEVELOPMENT OF CERTAIN DISEASES IN ADULT LIFE.	2021	
                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                           
16  360  29 AMBIENT AIR POLLUTION AND BIOMARKERS OF HEALTH EFFECT. RECENTLY, THE AIR POLLUTION SITUATION OF OUR COUNTRY IS VERY SERIOUS ALONG WITH THE DEVELOPMENT OF URBANIZATION AND INDUSTRIALIZATION. STUDIES INDICATE THAT THE EXPOSURE OF AIR POLLUTION CAN CAUSE A RISE OF INCIDENCE AND MORTALITY OF MANY DISEASES, SUCH AS CHRONIC OBSTRUCTIVE PULMONARY DISEASE (COPD), ASTHMA, MYOCARDIAL INFARCTION, AND SO ON. HOWEVER, THERE IS NOW GROWING EVIDENCE SHOWING THAT SIGNIFICANT AIR POLLUTION EXPOSURES ARE ASSOCIATED WITH EARLY BIOMARKERS IN VARIOUS SYSTEMS OF THE BODY. IN ORDER TO BETTER PREVENT AND CONTROL THE DAMAGE EFFECT OF AIR POLLUTION, THIS ARTICLE SUMMARIZES COMPREHENSIVELY EPIDEMIOLOGICAL STUDIES ABOUT THE BAD EFFECTS ON THE BIOMARKERS OF RESPIRATORY SYSTEM, CARDIOVASCULAR SYSTEM, AND GENETIC AND EPIGENETIC SYSTEM EXPOSURE TO AMBIENT AIR POLLUTION.	2017	
                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                            
17  625  36 BIOLOGICAL AGE AND ENVIRONMENTAL RISK FACTORS FOR DEMENTIA AND STROKE: MOLECULAR MECHANISMS. SINCE THE DEVELOPMENT OF ANTIBIOTICS AND VACCINATION, AS WELL AS MAJOR IMPROVEMENTS IN PUBLIC HYGIENE, THE MAIN RISK FACTORS FOR MORBIDITY AND MORTALITY ARE AGE AND CHRONIC EXPOSURE TO ENVIRONMENTAL FACTORS, BOTH OF WHICH CAN INTERACT WITH GENETIC PREDISPOSITIONS. AS THE AVERAGE AGE OF THE POPULATION INCREASES, THE PREVALENCE AND COSTS OF CHRONIC DISEASES, ESPECIALLY NEUROLOGICAL CONDITIONS, ARE RAPIDLY INCREASING. THE DELETERIOUS EFFECTS OF AGE AND ENVIRONMENTAL RISK FACTORS, DEVELOP CHRONICALLY OVER RELATIVELY LONG PERIODS OF TIME, IN CONTRAST TO THE RELATIVELY RAPID DELETERIOUS EFFECTS OF INFECTIOUS DISEASES OR ACCIDENTS. OF PARTICULAR INTEREST IS THE HYPOTHESIS THAT THE DELETERIOUS EFFECTS OF ENVIRONMENTAL FACTORS MAY BE MEDIATED BY ACCELERATION OF BIOLOGICAL AGE. THIS HYPOTHESIS IS SUPPORTED BY EVIDENCE THAT DIETARY RESTRICTION, WHICH UNIVERSALLY DELAYS AGE-RELATED DISEASES, ALSO AMELIORATES DELETERIOUS EFFECTS OF ENVIRONMENTAL FACTORS. CONVERSELY, BOTH AGE AND ENVIRONMENTAL RISK FACTORS ARE ASSOCIATED WITH THE ACCUMULATION OF SOMATIC MUTATIONS IN MITOTIC CELLS AND EPIGENETIC MODIFICATIONS THAT ARE A MEASURE OF "BIOLOGICAL AGE", A BETTER PREDICTOR OF AGE-RELATED MORBIDITY AND MORTALITY THAN CHRONOLOGICAL AGE. HERE WE REVIEW EVIDENCE THAT ENVIRONMENTAL RISK FACTORS SUCH AS SMOKING AND AIR POLLUTION MAY ALSO DRIVE NEUROLOGICAL CONDITIONS, INCLUDING ALZHEIMER'S DISEASE, BY THE ACCELERATION OF BIOLOGICAL AGE, MEDIATED BY CUMULATIVE AND PERSISTENT EPIGENETIC EFFECTS AS WELL AS SOMATIC MUTATIONS. ELUCIDATION OF SUCH MECHANISMS COULD PLAUSIBLY ALLOW THE DEVELOPMENT OF INTERVENTIONS WHICH DELAY DELETERIOUS EFFECTS OF BOTH AGING AND ENVIRONMENTAL RISK FACTORS.	2022	
                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                             
18 3106  32 GENOMICS AND THE RESPIRATORY EFFECTS OF AIR POLLUTION EXPOSURE. ADVERSE HEALTH EFFECTS FROM AIR POLLUTANTS REMAIN IMPORTANT, DESPITE IMPROVEMENT IN AIR QUALITY IN THE PAST FEW DECADES. THE EXACT MECHANISMS OF LUNG INJURY FROM EXPOSURE TO AIR POLLUTANTS ARE NOT YET FULLY UNDERSTOOD. STUDYING THE GENOME (E.G. SINGLE-NUCLEOTIDE POLYMORPHISMS (SNP) ), EPIGENOME (E.G. METHYLATION OF GENES), TRANSCRIPTOME (MRNA EXPRESSION) AND MICRORNAOME (MICRORNA EXPRESSION) HAS THE POTENTIAL TO IMPROVE OUR UNDERSTANDING OF THE ADVERSE EFFECTS OF AIR POLLUTANTS. GENOME-WIDE ASSOCIATION STUDIES OF SNP HAVE DETECTED SNP ASSOCIATED WITH RESPIRATORY PHENOTYPES; HOWEVER, TO DATE, ONLY CANDIDATE GENE STUDIES OF AIR POLLUTION EXPOSURE HAVE BEEN PERFORMED. CHANGES IN EPIGENETIC PROCESSES, SUCH DNA METHYLATION THAT LEADS TO GENE SILENCING WITHOUT ALTERING THE DNA SEQUENCE, OCCUR WITH AIR POLLUTANT EXPOSURE, ESPECIALLY GLOBAL AND GENE-SPECIFIC METHYLATION CHANGES. RESPIRATORY CELL LINE AND ANIMAL MODELS DEMONSTRATE DISTINCT GENE EXPRESSION SIGNATURES IN THE TRANSCRIPTOME, ARISING FROM EXPOSURE TO PARTICULATE MATTER OR OZONE. PARTICULATE MATTER AND OTHER ENVIRONMENTAL TOXINS ALTER EXPRESSION OF MICRORNA, WHICH ARE SHORT NON-CODING RNA THAT REGULATE GENE EXPRESSION. WHILE IT IS CLEARLY IMPORTANT TO CONTAIN RISING LEVELS OF AIR POLLUTION, STRATEGIES ALSO NEED TO BE DEVELOPED TO MINIMIZE THE DAMAGING EFFECTS OF AIR POLLUTANT EXPOSURE ON THE LUNG, ESPECIALLY FOR PATIENTS WITH CHRONIC LUNG DISEASE AND FOR PEOPLE AT RISK OF FUTURE LUNG DISEASE. CAREFUL STUDY OF GENOMIC RESPONSES WILL IMPROVE OUR UNDERSTANDING OF MECHANISMS OF LUNG INJURY FROM AIR POLLUTION AND ENABLE FUTURE CLINICAL TESTING OF INTERVENTIONS AGAINST THE TOXIC EFFECTS OF AIR POLLUTANTS.	2012	
                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                               
19 1371  34 DEVELOPMENTAL ORIGINS OF HEALTH AND DISEASE: NEW INSIGHTS. EPIDEMIOLOGICAL AND ANIMAL STUDIES SHOW THAT SMALL CHANGES IN THE DEVELOPMENTAL ENVIRONMENT CAN INDUCE PHENOTYPIC CHANGES AFFECTING AN INDIVIDUAL'S RESPONSES TO THEIR LATER ENVIRONMENT. THESE MAY ALTER THE RISK OF CHRONIC DISEASE SUCH AS METABOLIC SYNDROME OR CARDIOVASCULAR DISEASE. RECENT RESEARCH SHOWS THAT ANIMALS EXPOSED TO SUCH A MISMATCH BETWEEN PRENATAL AND POSTNATAL ENVIRONMENT DEVELOP OBESITY, REDUCED ACTIVITY, LEPTIN AND INSULIN RESISTANCE, ELEVATED BLOOD PRESSURE AND VASCULAR ENDOTHELIAL DYSFUNCTION. EPIGENETIC PROCESSES ARE INVOLVED IN SUCH EFFECTS, TARGETED TO PROMOTER REGIONS OF SPECIFIC GENES IN SPECIFIC TISSUES. SUCH FINE CONTROL OF GENE EXPRESSION SUGGESTS THAT THE MECHANISMS HAVE BEEN RETAINED THROUGH EVOLUTION THROUGH THEIR ADAPTIVE ADVANTAGE, RATHER THAN REPRESENTING EXTREME EFFECTS OF DEVELOPMENTAL DISRUPTION AKIN TO TERATOGENESIS. THERE MAY BE ADAPTIVE ADVANTAGE IN A DEVELOPMENTAL CUE INDUCING A PHENOTYPIC CHANGE IN GENERATIONS BEYOND THE IMMEDIATE PREGNANCY, AND A RANGE OF DATA THAT SUPPORT THIS CONCEPT. IN ANIMALS, EPIGENETIC EFFECTS SUCH AS DNA METHYLATION CAN BE PASSED TO SUCCESSIVE GENERATIONS. ENVIRONMENTAL TOXINS, INCLUDING ENDOCRINE DISRUPTORS, MAY INDUCE GREATER RISK OF CHRONIC DISEASE, EVEN AT LOW EXPOSURE LEVELS, IF THEY AFFECT SUCH NORMAL DEVELOPMENTAL EPIGENETIC PROCESSES. APPROPRIATE INTERVENTIONS MAY HAVE LONG-TERM MULTIGENERATIONAL EFFECTS TO REDUCE THE RISK OF CHRONIC DISEASE.	2008	
                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                     
20  653  33 BISPHENOL A, HYPERTENSION, AND CARDIOVASCULAR DISEASES: EPIDEMIOLOGICAL, LABORATORY, AND CLINICAL TRIAL EVIDENCE. BISPHENOL A (BPA) EXPOSURE HAS BECOME ONE OF THE MOST COMMON ENVIRONMENTAL CHEMICAL EXPOSURES IN HUMANS. THERE IS GROWING EVIDENCE REGARDING AN ASSOCIATION BETWEEN BPA EXPOSURE, HYPERTENSION, AND CARDIOVASCULAR DISEASES (CVD). IF BPA EXPOSURE IS INDEED ASSOCIATED WITH RAISED BLOOD PRESSURE AND CVD, IT WOULD BE A MAJOR PUBLIC HEALTH PROBLEM. THEREFORE, WE REVIEWED THE EPIDEMIOLOGICAL, LABORATORY, AND CLINICAL TRIAL EVIDENCE FOR AN ASSOCIATION BETWEEN BPA EXPOSURE, CVD, AND HYPERTENSION, AND DISCUSSED THE POSSIBLE MECHANISMS IN THIS ARTICLE. CROSS-SECTIONAL STUDIES IN VARIOUS ETHNICITIES SUGGESTED A POSSIBLE ASSOCIATION BETWEEN BPA EXPOSURE AND HYPERTENSION; THIS ASSOCIATION WAS SUPPORTED BY A PANEL STUDY AND A RANDOMIZED CLINICAL TRIAL. DESPITE THE DISCORDANCE AMONG CROSS-SECTIONAL STUDIES ABOUT AN ASSOCIATION BETWEEN BPA EXPOSURE AND CVD, A LONGITUDINAL STUDY SHOWS THAT BPA EXPOSURE IS A RISK FACTOR FOR CVD. THE EFFECTS OF BPA EXPOSURE SUCH AS ENDOCRINAL DISTURBANCE, INDUCTION OF OXIDATIVE STRESS AND INFLAMMATION, EPIGENETIC CHANGE, AND LINKS WITH OTHER CHRONIC DISEASES MAY HIGHLIGHT A POSSIBLE MECHANISM BETWEEN BPA EXPOSURE, CVD, AND HYPERTENSION. TO CLARIFY THE CAUSAL RELATIONSHIP, WELL-DESIGNED STUDIES ARE NEEDED IN THE FUTURE.	2016
