Di-2-ethylhexyl phthalate (DEHP) induced lipid metabolism disorder in liver via activating the LXR/SREBP-1c/PPARα/γ and NF-κB signaling pathway

Di-2-ethylhexyl phthalate (DEHP) has been widely used in many fields (agricultural products, medical instruments, and food packing). As an environmental contaminant, DEHP has a negative impact on human and animal health, and thus toxicity caused by DEHP is increasingly serious health concern. Nevertheless, DEHP-induced liver damage in quail remains unclear. To investigate the mechanism of liver damage caused by DEHP, male quail were treated with DEHP (250, 500, and 750 mg/kg) by gavage. Notably, DEHP exposure results in increased blood lipids and the accumulation of triglycerides (TG), total cholesterol (TC), and non-esterified fatty acid (NEFA) in the liver. Histopathological analysis showed that steatosis and inflammatory cell infiltration were observed in the liver tissue of quails exposed to DEHP. The results…
