The Spearman’s correlation analysis found that the expression of HNF-1B in HCC tissue had a positive correlation with expression of K7 (r = 0.463, P < 0.001), K19 (r = 0.286, P < 0.001), EpCAM (r = 0.210, P = 0.004), and OV6 (r = 0.279, P < 0.001) (Fig. 3C). Here, KRT19 is linked to hepatocellular carcinoma.
