ABCB4 and nonpapillary renal cell carcinoma: Consistent with the bioinformatics analysis, the expression levels of ABCB4, ASNS, CREBBP, PIK3R6, SNHG11, and SNHG20 were upregulated (Figure 5A), while the expression levels of FAAH2, HS3ST3A1, MED25, OXCT1, PLA2G6, and RAB14 were downregulated (Figure 5B) in ccRCC tissues compared with adjacent normal tissue samples.
