CRAF Methylation by PRMT6 Regulates Aerobic Glycolysis–Driven Hepatocarcinogenesis via ERK‐Dependent PKM2 Nuclear Relocalization and Activation

Abstract

Most tumor cells use aerobic glycolysis (the Warburg effect) to support anabolic growth and promote tumorigenicity and drug resistance. Intriguingly, the molecular mechanisms underlying this phenomenon are not well understood. In this work, using gain‐of‐function and loss‐of‐function in vitro studies in patient‐derived organoid and cell cultures as well as in vivo positron emission tomography–magnetic resonance imaging animal models, we showed that protein arginine N‐methyltransferase 6 (PRMT6) regulates aerobic glycolysis in human hepatocellular carcinoma (HCC) through nuclear relocalization of pyruvate kinase M2 isoform (PKM2), a key regulator of the Warburg effect.
