Objective:
The developmental origins hypothesis relates in utero exposures to endocrine disrupting chemicals (EDCs) to children’s physical growth and maturation and the later development of chronic diseases, including metabolic syndrome, a condition affecting up to 25% of U.S. adults and 30% of obese adolescents. Few studies have considered whether subsequent exposures during the pubertal transition may exacerbate impact of prenatal EDC mixtures on growth, maturation and the risk of metabolic syndrome. This center will test the overarching hypothesis that in utero and peripubertal exposures to mixtures of EDCs (BPA, phthalates, lead, cadmium) will, via epigenetic mechanisms, lead to changes in gene expression and alter the tempo of physical growth and maturation as well as metabolic function and increase risk of metabolic syndrome. Because nutrients may serve as agonists or antagonists of toxic effects of environmental chemicals, we further hypothesize that dietary intake will modify the impact of EDC mixtures on metabolic outcomes.
The Specific Aims of the University of Michigan Children’s Environmental Health and Disease Protection Center (UM-CEHC) are to:
- Assess the impact of in utero and peripubertal exposures to mixtures of EDCs (bisphenol A, phthalates, lead and cadmium) on linear growth and weight status (BMI), sexual maturation and reproductive hormones.
- Determine whether EDC mixtures (BPA, phthalates, lead, cadmium) via epigenetic mechanisms induce oxidative stress (tyrosine oxidation products), disrupt metabolic homeostasis (free fatty acids, amino acids, Acyl-carnitine) and lead to changes in gene transcription and metabolic function.
- Conduct tissue- and age-specific unbiased epigenomic analyses (DNA methylation, chromatin structure, transcriptomics) to identify a subset of tissue-independent labile genes to serve as biomarkers of exposure-induced metabolic syndrome.
- Examine the role of dietary intake during pregnancy and adolescence in modifying the impact of EDC mixtures on metabolic homeostasis, oxidative stress and risk of metabolic syndrome.
- Foster career development by assisting new investigators in the advancement of their research skills and knowledge in translational and children's environmental health research.
- Share current research findings on the role that environmental exposures have on children's health in an accurate, relevant way that allows community members, healthcare professionals, and policy makers to incorporate this new knowledge into practice for the protection of children's health.
Progress Summary:
Research Projects
The University of Michigan Children’s Environmental Health and Disease Prevention Center’s (CEHC) three research projects are designed to provide scientific integration across shared environmental exposures and interrelated outcomes to examine the impact of EDC mixtures (bisphenol A, phthalates, lead, cadmium) in utero and during the pubertal transition on physical growth and maturation and leading to alterations in metabolic homeostasis, oxidative stress and metabolic syndrome, using human and animal models. Projects 1 and 2 are human studies, both conducted within the Early Life Exposures in Mexico to ENvironmental Toxicants (ELEMENT) birth cohorts that have been successfully followed for nearly two decades. In addition to ELEMENT participants overseen by Drs. Meeker (Project 1) and Peterson (Project 2), the Michigan Mother Infant Pairs (MMIP) cohort, a U.S. study population established by MPI Padmanabhan, is included in Project 2 of the UM CEHC to extend findings from the ELEMENT cohort to a U.S. study population. Whereas Project 1 focuses on the impact of metals (Cd, Pb) and EDCs (BPA and phthalates) in utero and during peripuberty on children’s growth and sexual maturation (Overall Aim 1) in ELEMENT, Project 2 considers the effect of EDC exposures via epigenetic mechanisms to fetal and peripubertal alterations in metabolic homeostasis and oxidative stress and the potential modifying role of diet (Overall Aims 2, 3, and 4) in both ELEMENT and MMIP cohorts. To parallel the human studies, Project 3 utilizes a mouse model of perinatal environmental exposures to address the influence of perinatal and peripubertal exposure mixtures and diet on life course offspring metabolic status, reproductive development and epigenetic gene regulation (Aims 2, 3, and 4).
Progress for Project 1 in Year 2 included the development of a new exposure assessment of urinary concentrations of phthalate metabolites and BPA at multiple time points in pregnancy, which will allow us to assess potential windows of susceptibility to exposure related developmental effects. Archived urine samples from mothers during their third trimester in pregnancy and from children during peripubertal development also were analyzed for cadmium and a number of other metals. Protocols were finalized for the collection of new biologic and survey data on ELEMENT participants, and fieldwork began in Quarter 3. Recruitment has been faster than originally planned, and we are on track for finishing the first data collection on time or ahead of schedule. We published two papers relevant to Project 1 using our P20 CEHC data (upon which the P01 CEHC builds) on associations between in utero or peripubertal exposure to EDCs and sexual maturation. Our findings among boys were published in the journal Reproductive Toxicology (Ferguson, et al. Reproductive Toxicology 2014;47:70-76). Our findings among girls were presented by Dr. Watkins at the 2014 International Society of Environmental Epidemiology (ISEE) annual conference in Seattle, Washington, and were published in the journal Environmental Research (Watkins, et al. Environmental Research 2014;134:233-241). We also continued to utilize U.S. NHANES data to test hypotheses relevant to Project 1, and published a manuscript examining cross-sectional associations between phthalate metabolites and testosterone levels among men, women and children (Meeker and Ferguson; Journal of Clinical Endocrinology and Metabolism 2014;99(110:4346-4352). Among boys 6-12 years old, ages which overlap with boys from our study presented above, DEHP metabolites were strongly associated with a decrease in testosterone, which is consistent with new results from the ELEMENT cohort (Ferguson, et al. Reproductive Toxicology 2014;47:70-76). Dr. Peterson also presented our analysis of lead exposure at numerous developmental time periods in relation to sexual maturation in a talk at the 2014 ISEE annual conference in Seattle, Washington.
Progress for Project 2 in Year 2 included the development of a new exposure assessment of concentrations of BPA and phthalates metabolites at multiple time points in pregnancy and analysis of cadmium in archived urine samples (via Project 1). Protocols were finalized for the collection of new biologic and survey data on ELEMENT participants. Fieldwork began in Quarter 3 and recruitment has been faster than originally planned. As noted above, we have re-recruited nearly one-half of the sample and are on schedule for finishing the first data collection time point as planned, midway through Year 3. Another accomplishment in Year 2 was the optimization of DNA methylation assays for a targeted profile of 12 candidate genes related to metabolism and growth using both ELEMENT and MMIP cohorts. Four manuscripts were published from Project 2.
MMIP Cohort: Analysis of matched samples from MMIP provided evidence of the use of maternal 3-nitrotyrosine as a biomarker for offspring health. These findings were published as part of a multi-species study in Endocrinology (Veiga-lopez, et al.). Levels of unconjugated BPA and BPA glucuronide in 80 matching MMIP samples also were studied and findings indicate that higher uBPA exposure levels during first trimester and term are associated with gender-specific reduction in birth weight and increase in gestational length, respectively. A manuscript will be submitted reporting the impact of early pregnancy BPA levels on reduction of birth weight as an adverse health outcome. Pilot funds were received to test the feasibility of genome-wide DNA methylation analyses using a subsample of 24 cord blood and 12 matched placental samples from the MMIP cohort.
ELEMENT Cohorts: ELEMENT data were used to examine relationships between exposure mixtures and metabolic outcomes, including new statistical analysis of BPA and phthalates exposures and new data and preliminary analysis of untargeted metabolomics features. Year 2 also included examination of dietary intake in relation to toxicants, maturation and obesity using ELEMENT data. One study examined the effect modification by antioxidant intake of in utero exposure to lead on measures of metabolic syndrome risk at ages 8–15; another analyzed the effects of maternal intakes of selenium (Se), vitamin B2, calcium (Ca) and iron (Fe) on pubertal onset at ages 8–14; and a third considered whether age of introduction and cumulative sugar-sweetened beverage (SSB) consumption increases risk of obesity in children. The first two analyses were presented as posters at scientific meetings and the third is in press (Cantoral, et al. Pediatric Obesity 2015). Finally, sophisticated statistical analysis techniques were developed to correct for batch effects and increase statistical power needed to investigate associations between epigenetic modifications at candidate genes and exposures to environmental toxicants (Goodrich, et al. Epigenetics 2015). .
Project 3 is being implemented in the viable yellow agouti mouse model. In Year 2, six cohorts of mating pairs and litters were established and followed until 10 months of age to assess whether in utero high-fat diets modify the effects of perinatal BPA exposure on metabolic, hormonal, and oxidative stress parameters throughout the life course, and to identify DNA methylation alterations underlying such effects. Data analyses of PND10 offspring and maternal (dam) tissues are underway with two papers drafted that focus on fetal programming of metabolic and oxidative stress pathways in early life. Data on weight, fertility and birth outcomes suggest differences between exposure groups. For example, offspring survival rate was the lowest among the control diet + BPA exposure group. Preliminary analyses examining oxidative stress in PND10 liver suggest that Western diet + BPA exposure results in a more oxidized intracellular environment. Preliminary shotgun lipidomics analyses in female 10 month-old offspring reveal differences in long-chain polyunsaturated fatty acids (LC-PUFAs) between mice prenatally exposed to control vs. Western diet. Additional detail is provided in the Project 3 description. A number of abstracts detailing preliminary analyses from these cohorts have been accepted for presentation at upcoming meetings.
Data Management and Modeling Core (DMMC): In Year 2, the DMMC not only provided data analysis to support the three research projects but also the development of grant applications, including a K99/R00 submitted by Dr. Goodrich informed by work completed for Project 2 on targeted fatty acids and DNA methylation. Dr. Peter Song, Director of the DMMC, also submitted a revised R01 application , which was ranked at the 8th percentile, to focus on the development of novel statistical methodologies and efficient algorithms to evaluate, interpret and predict environmental risk of early life exposure on child health and development outcomes. In addition to analysis, a major accomplishment of the DMMC was creation of methods for cleaning, standardizing and normalizing more than 9,000 metabolic features and for relating these to biochemical pathways impacted by Pb exposure. The DMMC has established a system to integrate the previous P20 database with the P01 database to facilitate efficient data management and analysis, that includes several types of high-dimensional data such as metabolomics, accelerometry data, etc. Research regarding the DMMC methodology of handling inter-batch heterogeneities in the analysis of metabolomics was presented and awarded top five among posters presented at ENAR, the largest biostatistics conference in the world. A data management plan also was developed in Year 2 to capture the DMMC processes and procedures for transferring, sharing, managing and storing data.
Community Outreach and Translation Core (COTC): In Year 2, our COTC worked at the local and regional level with our Community Advisory Board (CAB) in Kent County, Michigan, which includes representatives from Head Start for Kent County, the Healthy Homes Coalition, and the Kent County Health Department. These three organizations have been central to identifying children’s environmental health issues and opportunities for improvement in Kent County. In addition, our CAB has partnered with the West Michigan Environmental Action Council (WMEAC) and the Asthma Network of West Michigan through a collaborative process and a created a partnership with Grand Valley State University, to produce maps illustrating the prevalence and burden of asthma on low-income preschool-age children in Kent County. These maps are being used in presentations to community and other stakeholders to address childhood asthma in Kent County, Michigan. Advancements in CEHC outreach also were achieved through UM contributions to a CEHN white paper. Additionally, the COTC Director, Dr. Miller, and Associate Director (Seema Jolly) attended the October 2014 CEHC meeting in Boston. In March 2015, Lindsey Mitchell, MPH, replaced Ms. Jolly as Center Manager and COTC Associate Director. The Director and Associate Director are active participants in the COTC workgroup where best practices for disseminating education and information to the community are shared. Conference calls with the University of Illinois COTC and the Region 5 Pediatric Environmental Health Specialty Unit (PEHSU) also were held to discuss strategies for disseminating research from the CEHCs to the PEHSUs and to explore how the PEHSUs may be able to advise the creation of educational materials for our community partners. In collaboration with our fieldwork host site in Mexico, the Instituto Nacional de Salud Pública, we also are identifying ways to disseminate research to the ELEMENT cohort. This includes creation of a subcommittee to plan for and define specific methods for this outreach, development of an information sheet that thanks participants for their contributions and provides program updates, and development of a participant questionnaire to learn about the participants’ feedback from their experience in the study. This questionnaire also will help identify opportunities for improvement. In addition, the COTC also began development of a CEHC website at the end of Year 2 that includes information about the center, research projects and findings, the research team, outreach initiatives and more.
Future Activities:
Research Projects: In Year 3, we will finish the first P01 data collection on all ELEMENT subjects and will begin planning for the start of the second data collection to take place in Quarter 4, Year 3. For Project 1, we will utilize our new urinary metals data to address Aim 2 by evaluating how exposure to EDC mixtures (phthalates, BPA, lead, cadmium) during development affect sexual maturation and reproductive hormone levels. For Aim 3, we will utilize our newly available urinary phthalate metabolite and BPA data to identify potential windows of susceptibility during pregnancy and to explore interactions between in utero and peripubertal exposures and their impact on child growth, sexual maturation, and reproductive hormone levels. In addition, as new data from the first P01 visit become available we will continue to expand our analyses to include this new information, and begin to examine associations between EDC exposure and growth velocities (Aim 1).
As part of Project 2 activities related to the ELEMENT cohort, we will focus on statistical analyses, toxicant-diet interactions in relation to metabolic outcomes, and complete pilot analyses of DNA methylation. Also in Project 2, we plan to use MMIP samples to undertake untargeted metabolomics analyses on first trimester and cord blood samples, maternal urinary phthalate measures and relate changes in phthalates and BPA to metabolites and pregnancy outcomes. Bisulfite sequencing will also commence on cord blood samples and we will optimize assays for qPCR gene expression. In Year 2 (April 2015), we applied for and received an Administrative Supplement to Project 2 entitled: High-Dimensional Epigenomic and Metabolomic Responses to Metal and EDC Exposures to be implemented from July 1, 2013. The supplement will examine the effect of repeated exposures to metals and EDCs in pregnancy and adolescence on novel, high-dimensional markers of metabolic homeostasis in longitudinal subsamples from the MMIP and ELEMENT (Mexico City) projects, including lipidomics and untargeted metabolomics and the potential mediation of these associations via changes in genome-wide DNA methylation.
For Project 3, we will begin studies on phthalates mixtures and Pb and high fat diets. Also, during Year 3, the biospecimens collected for Aim 1 and in the next reporting period will be used for Aim 3 to assess epigenetic tissue specificity and time-dependent epigenetic drift using genome wide whole methylome, transcriptome, and histone mark analysis.
The DMMC will continue to provide timely and effective statistical and bioinformatics support for all projects, data management and integration of existing data into a streamlined system. In addition, the DMMC will complete the creation of a P01 database and dictionary for the variables available in the database. Participation of the DMMC in dissemination of research findings, including writing of manuscripts and presentations, also will continue. A major focus in Year 3 will be the completion of the initial analysis of untargeted and targeted metabolites and application of advanced statistical modeling to analyze exposure to EDCs. Dr. Song has been invited to provide a presentation on statistical methods to relate toxicants to DNA methylation in epigenetics to be convened September 2-3, 2015, by the EPA.
The COTC will continue partnerships in Kent County, Michigan in Year 3 and work to actively disseminate findings from our asthma mapping project. This will include presentations at multiple upcoming local and statewide events as well as promotion through social media and articles. We also will work to create similar maps using larger state data. Additionally, we will work with the ELEMENT PI team on strategies to disseminate project findings to the community and enhance participant engagement. A new collaboration with the Healthy Environments Partnership at the University of Michigan also will be established to strengthen the effort to address child environmental health issues in Southeast Michigan. The CEHC website also will be finalized and go live in Quarter 1 of Year 3.
