Our findings revealed hepatic inhibition of PI3K/Akt pathway and reduction in bcl2 levels and the elevation in hepatic cleaved caspase 3, p53, and bax levels during the intrahepatic cholestasis induced by ANIT, which further suggest the activation of oxidative stress condition and induction of the apoptotic pathways. The gene discussed is TP53; the disease is intrahepatic cholestasis.
