- This study was aimed at comparing the toxicity effects on cell viability and the obesogenic activity of Bisphenol A (BPA) and its analogues, Bisphenol S (BPS) and Bisphenol F (BPF), by in vitro assays with a preadipocytic 3T3-L1 cell line. To compare the toxic potential and select the concentrations of each chemical not showing a decrease in cell viability, MTT assay was performed. The cell phenotype was determined in differentiated 3T3-L1 adipocytes by red oil O staining. To determine the expression levels of the different adipogenic proteins the Western Blot test was performed. The results from MTT assay showed a greater toxic effect of BPA - at equal and even lower concentrations-than its analogues. However, BPS followed by BPF showed a greater neutral lipid storage capacity than BPA, which was reflected in the increase of the protein expression of CCAAT/enhancer binding protein α (C/EBPα), peroxisome proliferator-activated receptor gamma γ (PPARγ) and acid-binding protein 4 (FABP4). In summary, these BPA analogues -especially BPS- present a greater endocrine potential activity than BPA.
