Among these patients, 69.2% (27/39) HCC tissues were positive for YAP expression in both the nuclei and cytoplasm (Figure 1(a)), whereas 41.0% (16/39) adjacent nontumor tissues were positive for YAP expression (Figure 1(b)); 66.7% (26/39) and 61.5% (24/39) of tumor tissues were, respectively, positive for TAZ and AREG (Figures 1(c) and 1(e)). This evidence concerns the gene AREG and hepatocellular carcinoma.
