ZEB1 and nonpapillary renal cell carcinoma: In particular, the expression of PRMT1 and ZEB1 in ccRCC, as well as low-nuclear tumor grade and low-tumor stage were significantly associated with better cancer-specific survival (p = 0.029, p = 0.009, p < 0.001 and p < 0.001, respectively) (Fig. 4 a-d; Table 8).
