More specifically, we found significant positive correlations between TOB2 and stromal score in HNSC and PCPG, BTG1 in BRCA, COAD, GBM, KIRC, KIRP, LAML, LIHC, MESO, PAAD, PCPG, PRAD, SKCM, STAD, TGCT, THCA, UCEC, BTG2 in BRCA, KIRC, LAML, LIHC, LUSC, PRAD, SKCM, STAD, TGCT, THCA and UVM, BTG3 in LGG, PRAD and THCA, and BTG4 in COAD, GBM and LUAD (P < 0.001). This evidence concerns the gene BTG1 and glioblastoma.
