CDK4 is up‐regulated in glioblastoma tissues and cell lines. A, Analysis of TCGA datasets showing high expression of CDK4 mRNA in glioblastoma specimens compared with nontumour brain tissues. B, IHC analysis of CDK4 expression in glioblastoma specimens and normal brain tissues. Scale bar, 100 μm. C, Western blotting of CDK4 expression in glioblastoma specimens and normal brain tissues. D, Comparison of CDK4 expression between NHAs and glioblastoma cell lines by western blotting
