METTL13 and nonpapillary renal cell carcinoma: On the one hand, the expression level of METTL13 in ccRCC is likely to be considered a potential molecular indicator in the future, which may assist pathologists in diagnosing clinicopathological characters of the tumors and predicting patients’ prognosis; on the other hand, we could propose new methods using METTL13 agonists, taking advantage of METTL13's tumor suppressing role in ccRCC for renal cancer therapy.
