TNF and hepatocellular carcinoma: Importantly, the higher level of p‐STAT3, E‐cadherin and Vimentin were found in liver injury groups for 6 and 10 weeks compared to 4 weeks (G2/G3 vs G1; Figure 3H), indicating that the increased levels of inflammatory factors (TNF‐α and IL‐6) in liver tissues were concordant with the activation extent of STAT3/EMT signalling pathway in HCC (Figure 3A,C).
