BMAL2 and nonpapillary renal cell carcinoma: We also verified the associations of ARNTL2 with these three genes by analyzing the RNA-seq of ccRCC cell lines in Cancer Cell Line Encyclopedia (CCLE) database, the results demonstrated that these three genes are significantly correlated with the expression of ARNTL2 in ccRCC cell lines (p < 0.05; Fig. 6c).
