Bisphenol AF (BPAF) has been widely used as a main alternative to bisphenol A (BPA), and previous in vitro studies have shown that BPAF has higher reproductive toxicity potentials than BPA. However, data on in vivo toxicity of BPAF is still limited. In this study, Sprague Dawley rats were exposed to BPAF (0, 50, and 100 mg/kg/day) during gestation to study toxicokinetics and reproductive toxicity in offspring.

Article Synopsis
  • Bisphenol AF (BPAF) is shown to transfer more easily from mother to fetus and accumulate in the offspring’s body compared to bisphenol A (BPA), raising health concerns during pregnancy.
  • A study on SD rats exposed to different doses of BPAF during gestation revealed significant bioaccumulation in liver, spleen, and kidneys, leading to various adverse health effects in the offspring, including organ damage and changes in gene expression related to metabolism and inflammation.
  • The research identified 217 altered metabolites in the spleen and significant enrichment in 9 biological pathways, highlighting the systemic toxicity of prenatal BPAF exposure and urging a reevaluation of its safety due to its widespread use.

Estrogen excess in females has been linked to a diverse array of chronic and acute diseases. Emerging research shows that exposure to estrogen-like compounds such as bisphenol S leads to increases in 17β-estradiol levels, but the mechanism of action is unclear. The aim of this study was to reveal the underlying signaling pathway-mediated mechanisms, target site and target molecule of action of bisphenol S causing excessive estrogen synthesis.

Bisphenol S (BPS) exhibited inhibitory effects on androgen synthesis, but its target of action remains unclear. We investigated the effects of BPS exposure at environmentally relevant concentrations (1 μg/L, 10 μg/L and 100 μg/L) for 48 h on androgen synthesis in rat ovarian theca cells and explored the underlying mechanisms, target site and target molecule. The results showed that BPS exposure inhibited the transcript levels of steroidogenic genes and reduced the contents of androgen precursors, testosterone and dihydrotestosterone.
