Moreover, SKP2 mRNA was found to be highly expressed in 15 tumors — BLCA, CESC, CHOL, COAD, ESCA, GBM, HNSCC, KIRC, LIHC, LUAD, LUSC, PCPG, READ, STAD, and UCEC, and the overexpression status of SKP2 in cancer tissues of CESC, COAD, and STAD was verified at the protein level. This evidence concerns the gene SKP2 and glioblastoma.
