As shown in Fig. 1B, the expression level of GAB2 mRNA increased in some tumors, such as CHOL, KICH, KIRC, LAML, LGG, LIHC, OV, PAAD, PCPG, SKCM, STAD, and TGCT; and the expression was reduced in cancer in ACC, BLCA, BRCA, CESC, DLBC, ESCA, HNSC, LUAD, LUSC, PRAD, THYM, UCEC, and UCS. Here, GAB2 is linked to cancer.
