Further analysis of the TCGA database indicated that CCNB2 exhibits high levels of expression across a spectrum of cancers, including PCa (Figure 6D, E) and the elevated level of its expression was positively correlated with Gleason score, age, and lymph node metastasis in PCa patients (Figure 6F, G, H), suggesting that the CCNB2 gene was a factor contributing to risk for PCa. This evidence concerns the gene CCNB2 and cancer.
