AIBP protects drug-induced liver injury by inhibiting MAPK-mediated NR4A1 expression.

ABSTRACT: Drug-induced liver injury (DILI) is an important adverse drug reaction that can lead to acute liver failure or even death in severe cases. AIBP is a binding protein of apolipoprotein AI involved in lipid metabolism and maintenance of oxidative respiration in mitochondria, but its role in DILI is unclear. By constructing AIBP knockout mice, overexpressing and knocking down AIBP in cell lines, we established animal and cell models of DILI. Using western blotting and real-time qPCR assay, we explored the influence of AIBP in activation of mitogen-activated protein kinases (MAPK) signal pathways and possible targets. AIBP was downregulated during hepatocyte injury. AIBP deficient mice develop severe liver injury and more sensitive to drug-induced cell death. Overexpression of AIBP protects cel
