HCC patients with higher expression of CDK1, BRCA1, TUBB, HSPA1A, HSPA1B, and HSPA4 showed significantly worse overall survival (Figure 5), while HCC patients with higher expression of CDK1, CLU7, BRCA1, and TUBB showed significantly worse disease-free survival (Figure 6). This evidence concerns the gene TUBB and hepatocellular carcinoma.
