Abstract

Maternal prenatal exposures, including bisphenol A (BPA), are associated with offspring's risk of disease later in life. Alterations in DNA methylation may be a mechanism through which altered prenatal conditions (e.g. maternal exposure to environmental toxicants) elicit this disease risk. In the Michigan Mother and Infant Pairs Cohort, maternal first-trimester urinary BPA, bisphenol F, and bisphenol S concentrations were tested for association with DNA methylation patterns in infant umbilical cord blood leukocytes ( = 69). We used the Illumina Infinium MethylationEPIC BeadChip to quantitatively evaluate DNA methylation across the epigenome; 822 020 probes passed pre-processing and quality checks. Single-site DNA methylation and bisphenol models were adjusted for infant sex, estimated cell-type proportions (determined using cell-type estimation algorithm), and batch as covariates. Thirty-eight CpG sites [false discovery rate (FDR) <0.05] were significantly associated with maternal BPA exposure. Increasing BPA concentrations were associated with lower DNA methylation at 87% of significant sites. BPA exposure associated DNA methylation sites were enriched for 38 pathways significant at FDR <0.05. The pathway or gene-set with the greatest odds of enrichment for differential methylation (FDR <0.05) was type I interferon receptor binding. This study provides a novel understanding of fetal response to maternal bisphenol exposure through epigenetic change.

摘要

孕妇孕期暴露,包括双酚A(BPA),与后代日后患疾病的风险相关。DNA甲基化改变可能是孕期状况改变(如母亲暴露于环境毒物)引发这种疾病风险的一种机制。在密歇根母婴队列研究中,检测了孕妇孕早期尿液中双酚A、双酚F和双酚S的浓度与婴儿脐带血白细胞(n = 69)中DNA甲基化模式的相关性。我们使用Illumina Infinium MethylationEPIC BeadChip对整个表观基因组的DNA甲基化进行定量评估;822020个探针通过了预处理和质量检查。单位点DNA甲基化和双酚模型针对婴儿性别、估计的细胞类型比例(使用细胞类型估计算法确定)以及批次作为协变量进行了调整。38个CpG位点[错误发现率(FDR)<0.05]与孕妇双酚A暴露显著相关。在87%的显著位点,双酚A浓度升高与较低的DNA甲基化相关。双酚A暴露相关的DNA甲基化位点在FDR<0.05时富集了38条显著通路。差异甲基化(FDR<0.05)富集可能性最大的通路或基因集是I型干扰素受体结合。本研究通过表观遗传变化为胎儿对母体双酚暴露的反应提供了新的认识。
