Among these cancers listed in the figure, we observed a significantly high expression level of GLUT1 in 17 cancer types (including ACC, BRCA, CESC, CHOL, COAD, GBM, HNSC, KIRC, LUAD, LUSC, OV, PAAD, READ, STAD, TGCT, UCEC, and UCS), and a significantly low expression level of GLUT1 in 3 cancer types (including KICH, LAML, and SKCM). Here, SLC2A1 is linked to cancer.
