To assess the expression level of RanGAP1 in cancer, we utilized The Cancer Genome Atlas (TCGA) database and observed elevated levels of RanGAP1 in several cancers, including Colon Adenocarcinoma (COAD) and Rectum Adenocarcinoma (READ) (Fig. 1A, B, Fig. S1A). The gene discussed is RANGAP1; the disease is cancer.
