Bisphenol A (BPA) has been widely reported to exert endocrine disrupting effects, including the induction of adipogenesis in cultured preadipocytes and intact animals. Because of the potential harm to human health, BPA is being substituted by structurally related bisphenols. Whether or not such BPA analogues are safe substitutes, however, remains largely unknown. Here, we investigated the potential of bisphenol B (BPB), bisphenol E (BPE), bisphenol F (BPF), bisphenol S (BPS), and 4-cumylphenol (4-CP) to affect lipid and hormone levels in 3 T3-L1 cells. We found that BPB, BPE, BPF, BPS, and 4-CP all affected lipid accumulation and leptin levels to the same extent and potencies as BPA. Based on these and other results, we conclude that these BPA analogues and 4-CP most likely will elicit similar effects on adipocytes as BPA. Using them to substitute BPA in products should be done with caution.
Keywords: BPA analogues; PPARγ; adipocytes; leptin; obesity.
