Acetaminophen (APAP) overdose is the leading cause of drug-induced acute liver injury. However, the underlying mechanisms appear to be multifaceted and there are few effective treatments. In this study, we used the 2′-Hydroxycinnamaldehyde (HCA), an active ingredient extracted from cinnamon stem bark to evaluate the therapeutic effect against APAP-induced ALI. The results indicated that pyruvate kinase M2 (PKM2)-mediated aerobic glycolysis may activate NLRP3 inflammasome in APAP-induced ALI, However, this process was prevented by HCA. Additionally, overexpression of PKM2 by adeno-associated virus (AAV9-PKM2) in vivo and plasmid (PKM2-OE) in vitro reversed the inhibition of NLRP3 inflammasome by HCA. Intriguingly, the HCA-triggered repressive pyroptosis was mediated through dephosphorylation and nuclear translocation of PKM2. Furthermore, the therapeutic effect of HCA on APAP-induced ALI was achieved by partially stimulating the Akt-mTOR signaling pathway, thus inhibiting the PKM2-NLRP3 axis. These findings elucidate that a potential drug to the clinical treatment of APAP overdose by HCA. |
