CCNF was significantly upregulated in BRCA, cervical squamous cell carcinoma and endocervical adenocarcinoma (CESC), CHOL, COAD, lymphoid neoplasm diffuse large B-cell lymphoma (DLBC), ESCA, HNSC, LUAD, LUSC, ovarian serous cystadenocarcinoma (OV), pancreatic adenocarcinoma (PAAD), READ, STAD, testicular germ cell tumors (TGCT), thymoma (THYM), UCEC and uterine carcinosarcoma (UCS) tissues than in normal tissues (P<0.0001) (Figure 1B). Here, CCNF is linked to testicular germ cell tumor.
