Obesity increases the risk of hepatocellular carcinoma (HCC) especially in men. Here the authors find a potential mechanistic explanation by showing that, in mice, obesity-induced STAT3 cooperates with the androgen receptor to activate the mTORC pathway through up regulation of CCRK, resulting in hepatic steatosis worsening and HCC development via metabolic and immune reprogramming.
