NAT10 and nonpapillary renal cell carcinoma: In addition, UALCAN (http://ualcan.path.uab.edu/analysis.html) and TISID8 data (http://cis.hku.hk/TISIDB/) showed that the expression of NAT10 in ccRCC was significantly higher in WHO/ISUP stage IV than in WHO/ISUP stage I (Fig. 1e, Supplementary Fig. S1h), and the immunohistochemical results were also consistent with the above results (Fig. 1f, g).
