Although roles and mechanisms of WTAP have been elucidated in several types of carcinoma, including colon carcinoma [12], cholangiocarcinoma [14], glioma [15], hepatocellular carcinoma [13], pancreatic carcinoma [8] and renal cell carcinoma [9], they remain elusive in ovarian cancer. This evidence concerns the gene WTAP and renal cell carcinoma.
