We investigated the potential of 10 environmentally relevant EDCs to affect key events of hepatic steatosis in HepG2 human hepatoma cells. Increased lipid droplet formation, a key marker of steatosis, was induced by PFOA, bisphenol F, DDE, butylparaben, and DEHP, within the non-cytotoxic concentration range of 1 nM-25 μM. Cadmium also induced this effect, but at concentrations impairing cell viability (>1 μM). At non-cytotoxic concentrations, these compounds, along with bisphenol A, dysregulated major genes controlling lipid homeostasis.

Bisphenol A downregulated the CPT1A gene involved in fatty acid oxidation. No significant effects on lipid droplet accumulation or lipid metabolism-related genes were observed for PFOS, bisphenol S, and dibutyl phthalate. Among the tested EDCs, lipid accumulation positively correlated with the expression of SREBF1, DGAT1, and CPT1A.
