The expression of six genes in HCC were assessed using starBase and showed that only TGFB2, BRAF, and NRAS expression levels were significantly upregulated in HCC (Figure 7C); survival analysis for the six genes revealed that high expression of three genes (BRAF, IGF1R, and NRAS) possessed poor prognosis of patients with HCC (Figure 7D); expression correlation analysis demonstrated that, among the six genes, only NRAS expression was negatively correlated with miR-145-5p expression in HCC (Figure 7E). The gene discussed is TGFB2; the disease is hepatocellular carcinoma.
