RUVBL1 and nonpapillary renal cell carcinoma: The Kaplan–Meier survival curves indicated a significantly poorer OS (p = 0.004) in ccRCC patients with a high RUVBL1 protein expression compared to those with a low expression (median OS of 867 and 1825 days, respectively; HR 1.86, 95% CI 1.21–2.87, p < 0.01; Figure 5, Table 4).
