TNF and hepatocellular carcinoma: In their study, Fang et al84 show that steatohepatitis, elevated expression of tumour necrosis factor (TNF)‐α and interleukin (IL)‐6, and the activation of the signal transducers and activators of transcription 3 (STAT3) and nuclear factor kappa‐light‐chain‐enhancer of activated B cells (NF‐κB) pathways were detected in liver parenchyma of hepatocyte‐specific ARID1A knockout mice, which might contribute to HCC tumorigenesis.
