In BLCA (Bladder Urothelial carcinoma), BRCA, CHOL (Cholangiocarcinoma), ESCA (Esophageal carcinoma), HNSC, KIRC (Kidney Renal Clear Cell carcinoma), KIRP (Kidney Renal Papillary Cell carcinoma), LUAD, THCA and UCEC, OAS1 expression was significantly higher in tumor tissues than that in adjacent normal tissues, whereas OAS1 expression was significantly lower in COAD and KICH (Kidney Chromophobe) than that in adjacent normal tissues (Figure 1A). This evidence concerns the gene OAS1 and chromophobe renal cell carcinoma.
