KEAP1 and hepatocellular carcinoma: Previous studies have shown that the higher Keap1 expression is closely related to longer progression‐free survival in non‐small cell lung cancer.[27] However, recent studies have shown that higher Keap1 protein expression levels are closely related to lower survival time in colorectal cancer.[28] In this study, we used a HCC liver tissue microarray to detect the expression of Keap1 and found that Keap1 expression in HCC tissues was higher than in para‐carcinoma tissues (Figure 2B).
