Abstract

Bisphenol A (BPA), a recognized endocrine-disrupting chemical, is used in the production of epoxy and polycarbonate resins. Since human exposure to BPA has been associated with increased cancer susceptibility, the market has shifted to products often labeled as "BPA free" containing BPA analogs such as bisphenol F (BPF) and bisphenol S (BPS). However, the European legislation on BPF and BPS is still unclear. This study analyzed the effects of BPA, BPF, and BPS exposure on human peripheral blood mononuclear cells by using in vitro micronucleus assay. Furthermore, it investigated the impact of bisphenols exposure on human endogenous retroviruses (HERVs) expression, which is implicated with the pathogenesis of several human diseases. The micronucleus assay revealed a significant genotoxic effect in peripheral blood cells after exposure to BPA and BPF at concentrations of 0.1, 0.05, and 0.025 μg/ml, and to BPS at 0.1 and 0.05 μg/ml. In addition, BPA exposure seems to upregulate the expression of HERVs, while a downregulation was observed after BPF and BPS treatments. Overall, our data showed the toxic effect of BPA and its analogs on circulating cells in the blood and demonstrated that they could modulate the HERVs expression.

摘要

双酚 A(BPA)是一种公认的内分泌干扰化学物质,用于生产环氧树脂和聚碳酸酯树脂。由于人类接触 BPA 与癌症易感性增加有关,市场已转向通常标有“不含 BPA”的产品,这些产品含有 BPA 类似物,如双酚 F(BPF)和双酚 S(BPS)。然而,关于 BPF 和 BPS 的欧洲法规仍不明确。本研究通过体外微核试验分析了 BPA、BPF 和 BPS 暴露对人外周血单个核细胞的影响。此外,还研究了双酚暴露对人类内源性逆转录病毒(HERVs)表达的影响,HERVs 表达与多种人类疾病的发病机制有关。微核试验显示,BPA 和 BPF 在 0.1、0.05 和 0.025μg/ml 浓度,以及 BPS 在 0.1 和 0.05μg/ml 浓度下暴露于外周血细胞后具有明显的遗传毒性作用。此外,BPA 暴露似乎上调了 HERVs 的表达,而 BPF 和 BPS 处理后则下调了 HERVs 的表达。总体而言,我们的数据显示了 BPA 及其类似物对血液中循环细胞的毒性作用,并表明它们可以调节 HERVs 的表达。
