According to a pan-cancer data set of TGCA, expression levels of SERPINE1 mRNA were significantly increased (p < 0.001) in breast invasive carcinoma (BRCA), colon adenocarcinoma (COAD), stomach adenocarcinoma (STAD), glioblastoma multiforme (GBM), kidney renal clear cell carcinoma (KIRC), and head and neck squamous cell carcinoma (HNSC). This evidence concerns the gene SERPINE1 and glioblastoma.
