More importantly, when we analysed HCC patients that co‐expressed both high c‐Myc and G9a, we could demonstrate a higher probability in terms of predicting overall survival than individual gene expression (Fig. 1K), suggesting that both c‐Myc and G9a plays important roles in HCC patient survival and could be used together as potential prognostic markers. The gene discussed is MYC; the disease is hepatocellular carcinoma.
