Abstract:

Bisphenol S (BPS), a substitute of bisphenol A (BPA), is widely used for manufacturing different polymers. Due to its wide range of applications, BPS has been frequently detected in the foodstuffs, environment and human blood and excreta. In this study, we examined the effects of the perinatal exposure to BPS on obesity development usingH NMR based on metabolomics strategy combined with gene expression analysis in male mouse offspring at a dosage of 100 ng/g bw/day. We found that perinatal exposure to BPS significantly increased the body weight, the weights of liver and epididymal white adipose tissue (epiWAT), serum alanine aminotransferase (ALT) activity, and the contents of triglyceride (TG) and cholesterol (T-Cho) in the liver. Histopathological analysis showed that lipids were accumulated significantly in liver tissues and epiWAT with BPS exposure. Furthermore, expressions of genes involved in the inflammatory pathways were significantly increased in liver tissues and epiWAT. Meanwhile, serum metabolomics study showed significant changes in the contents of metabolites associated with lipid and glucose metabolism. Correspondingly, the relative expression levels of genes involved in lipid and glucose metabolism were significantly changed in the liver tissue and epiWAT of male mouse offspring. In conclusion, these results showedthat perinatal exposure to BPS may increase the risk of obesity by interfering with lipid and glucose metabolism in male mouse offspring. The potential health risks of BPS in the human required further detailed studies evaluating.
