We further analyzed the genes in the core regulatory module and found that expression of EXO1, VCAN, has-miR-200c-5p, BMI1, has-miR-204-5p, and KIT was significantly correlated with HCC prognosis in all patients; and thus, these genes were considered key regulators (Figure 5A). The gene discussed is KIT; the disease is hepatocellular carcinoma.
