The aim of this research was to investigate the influence and potential mechanisms of Bisphenol BP (BPBP) on adipogenesis in 3T3-L1 cells. The results showed that low concentrations (0.01 μM) of BPBP promoted cell fat differentiation and triglyceride accumulation. RNA-seq data revealed differentially expressed genes related to adipocyte differentiation and adipogenesis after BPBP treatment, suggesting the activation of PPAR-γ signaling pathway as a key factor. This study provides evidence for the potential obesogenic effect of BPBP and calls for further research on its safety in food products.
Dihydrxytetraphenylmethane, also known as Bisphenol BP (BPBP), has been increasingly used in industrial production and more frequently detected in the environment as an alternative plasticizer of BPA. However, there are no reports about BPBP in food safety or its effects on cellular lipogenesis. The purpose of this research was to investigate the influence and potential mechanisms of BPBP on adipogenesis in 3T3-L1 cells. Cells were treated with 4 concentrations (0.01, 0.1, 1, and 10 & mu;M) of BPBP and the results showed that treatment with at low concentrations (0.01 & mu;M) promoted cell fat differentiation and triglyceride accumulation. RNA-seq data showed that a total of 370 differentially expressed genes between control and the low-dose BPBP-treated group were determined, including 227 upregulated genes and 143 downregulated genes. Some key genes related to adipo-cyte differentiation and adipogenesis were significantly enriched after BPBP treatment, including PPAR-& gamma;, Adi-poq, Nr1h3 and Plin1. Pathway analyses suggest that the activation of PPAR-& gamma; signaling pathway may be key for BPBP to promote adipocyte differentiation and fat accumulation. Our work provides evidence for the potential obesogenic effect of BPBP and may call for further research on the safety of the chemical in food products.
