Overdose of acetaminophen (APAP) is the leading cause of acute liver failure (ALF). Although mechanisms of APAP-induced liver injury are well known, those that affect the progression of APAP-induced liver disease and facilitate liver recovery are less understood. The sulfotransferase 2B1b (SULT2B1b) participates various of liver relative diseases including metabolic syndrome, chronic liver injury and hepatocellular carcinoma. Our previous study showed that SULT2B1b is transcriptional regulated by Hepatic Nuclear Factor 4α (HNF4α), which is essential for liver development and function. However, the importance of SULT2B1b in APAP-induced acute liver injury remains unknown. In this study, we examined the role of SULT2B1b in APAP-induced hepatotoxicity. We showed that hepatic overexpression of SULT2B1b in liver sensitized mice to APAP-induced liver injury, whereas ablation of Sult2B1b conferred resistance to the APAP hepatotoxicity. Indeed, upregulation of Sult2B1b by Hnf4α in wild type mice showed more severe liver injury and this effect was abolished in Sult2B1b knockout mice evidenced by comparable liver damage. Therefore, we conclude that SULT2B1b represents a potential therapeutic target for the prevention and treatment of APAP-induced acute liver injury.
