In the expression analysis results of matched tumors and normal tissues provided by GEPIA2.0, SLC2A1 was significantly upregulated in adrenocortical carcinoma (ACC), BRCA, CESC, COAD, glioblastoma multiforme (GBM), HNSC, KIRC, LUAD, LUSC, ovarian serous cystadenocarcinoma (OV), pancreatic adenocarcinoma (PAAD), READ, STAD, testicular germ cell tumors (TGCT), UCEC, and uterine carcinosarcoma (UCS) (Figure 1B). This evidence concerns the gene SLC2A1 and glioblastoma.
