Analysis of The Cancer Genome Atlas (TCGA) dataset (Figure 5A) of glioblastoma tissue specimens and the SKS dataset (Figure 5B) of patient-derived glioblastoma brain tumor initiating cells (BTICs) revealed no notable differential expression of RAD51 or its paralogs in PTEN-mutated or wild-type samples. Here, RAD51 is linked to glioblastoma.
