HIF1A and clear cell renal carcinoma: The RNA sequencing (RNAseq) data from The Cancer Genome Atlas (TCGA) Kidney Clear Cell Carcinoma (KIRC), TCGA Kidney Papillary Cell Carcinoma (KIRP), TCGA Kidney Chromophobe (KICH), and GTEx Kidney studies was analyzed to determine whether HIF1A and VEGFA were differentially expressed in the analyzed groups, where a two-fold change was considered significant.
