In contrast, WTAP expression was downregulated in breast invasive carcinoma, kidney renal papillary cell carcinoma, kidney chromophobe, bladder urothelial carcinoma, pancreatic adenocarcinoma, thyroid carcinoma, lung adenocarcinoma, and uterine corpus endometrial carcinoma samples compared with that in non-tumor tissues. This evidence concerns the gene WTAP and chromophobe renal cell carcinoma.
