In addition, 113 hub genes from the normal group, 48 hub genes from the tumor group, and 2 hub genes (CDK1 and KIF11) from both groups were included in the 9427 DEG (p ≤ 0.001 and p ≤ padj) sets, indicating differential expression between the normal and tumor tissues (Supplementary Table 9). The gene discussed is CDK1; the disease is neoplasm.
