HIF1A and VEGFA mRNA expressions obtained from the GDC TCGA Kidney Clear Cell Carcinoma (KIRC), GDC TCGA Kidney Papillary Cell Carcinoma (KIRP), and GDC TCGA Kidney Chromophobe (KICH) studies were analyzed to determine the median survival time (mst) and survival rate between low- and high-expression groups (Figure 4). Here, VEGFA is linked to clear cell renal carcinoma.
