Abstract:
Bisphenol S (BPS) has been gradually used in all kinds of productions. Our previous study has demonstrated that BPS increases the obesogenic effects of a high-glucose diet through regulating lipid metabolism in Caenorhabditis elegans (C. elegans). Whether the effects pass on to the next generations remains uncovered. In the present study, C. elegans was selected as the model organism to investigate the effects of BPS on lipid metabolism in multiple generations. Oil Red O staining and triglyceride assays showed that multi-generational exposure to BPS in C. elegans significantly increased the fat accumulation in wild type worms, while not in the daf-16 gene-deficient worms. In addition, BPS affected the expressions of fat-7 and acs-2 in four generations of C. elegans. Furthermore, BPS promotes fat storage in C. elegans of multiple generations by the daf-16/nhr-49-mediated signaling pathway.
