CTDSP1 and nonpapillary renal cell carcinoma: We also found that the increased expression of the predicted regulatory miRNAs for CTDSP1/2/L (mir-183, mir-15a, and mir-18a; see Table S4), is associated with worse prognosis in ccRCC (p < 0.01 for mir-183 and mir-18a; p < 0.05 for mir-15a, log-rank test; Figure S2A–C).
