The results showed that the expression level of CCNA2 was significantly different in different stages of ACC, BRCA, COAD, KICH, KIRC, KIRP, LUAD, SKCM, TGCT, and THCA (Figure S1), suggesting that CCNA2 may play an important role in progression of various carcinomas. This evidence concerns the gene CCNA2 and adrenal cortex carcinoma.
