In contrast, reduced NCKAP1 expression in renal clear cell carcinoma (KIRC), kidney renal papillary cell carcinoma (KIRP), kidney chromophobe renal cell carcinoma (KICH), and prostate adenocarcinoma (PRAD) was also identified (Figure 1A and Supplemental Figure S1A). Here, NCKAP1 is linked to clear cell renal carcinoma.
