Aflatoxin B1-Induced COX-2 Expression Promotes Mitophagy and Contributes to Lipid Accumulation in Hepatocytes In Vitro and In Vivo.

The results of the current study suggested that AFB1 increases the expression of COX-2, which, in turn, elevates the level of mitophagy, thereby disrupting the normal mitochondrial lipid metabolism and causing steatosis. Thus, this study implies that COX-2 may be a potential target for therapy against AFB1-induced steatosis.
