AURKB and nonpapillary renal cell carcinoma: To further narrow down the candidate prognosis-related genes, the LASSO Cox regression prognosis model was constructed according to the formula riskScore = geneExp*Coef (Fig. 1J), and the correlation coefficient for AURKB was greater (GTSE1 coef = 0.016, AURKB coef=0.021), suggesting a greater role for AURKB in ccRCC prognosis.
