The mechanism of DEHP-induced lipid accumulation in liver of female zebrafish.

Diethylhexyl phthalate (DEHP) is a typical environmental pollutant and poses a potential threat to organisms by disrupting the lipid metabolism. This study found that DEHP at environmental concentrations, led to lipid accumulation in female zebrafish, as indicated by significant increases in the content of total cholesterol, triglycerides and the lipid droplets, in a concentration-dependent manner. However, how DEHP induces the lipid accumulation remains poorly understood.
