Modulation of Atg5 Expression by Globular Adiponectin Contributes to Autophagy Flux and Suppression of Ethanol-Induced Cell Death in Liver Cells.
Abstract Globular adiponectin (gAcrp) protects liver cells from ethanol-induced apoptosis via induction of autophagy. However, the underlying mechanisms are unknown. The present study aims to investigate the potential role of autophagy-related protein 5 (Atg5), an essential Atg for the elongation of autophagosomes, in suppression of ethanol-induced cytotoxicity by gAcrp. Here, we demonstrated that suppression of Atg5 expression by ethanol was restored by pretreatment with gAcrp both in primary rat hepatocytes and human hepatoma cell line (HepG2). Moreover, ethanol-induced accumulation of p62 (sequestosome1), a mar...
