Bisphenols can enter the body, where they have potential adverse effects on human health, via different routes such as inhalation, dermally or orally. They are known as endocrine disrupting chemicals that activate signaling pathways by mimicking the estrogen actions. In this study, we aimed to investigate effects of bisphenol A (BPA), and its analogues bisphenol F (BPF) and bisphenol S (BPS) on MCF-10A cells and their impact mechanisms on autophagy, apoptosis and reduced glutathion levels. In comparison of the cytotoxic effects, while BPF and BPS showed dose-dependent high toxicity on MCF-10A cells, BPA exerted cytotoxic effects only at the highest doses. Caspase 3 and LC3B are strongly and positively correlated with BPF exposures while significant changes were not detected in the BPA and BPS applied groups. It was clearly observed that BPF and BPS displayed more toxic effects than BPA on human breast cells that are important targets for the bisphenols. These findings provide data for understanding the mechanisms for BPA, BPF and BPS-induced toxicity on human breast cells.
