NOC2L and chromophobe renal cell carcinoma: Among kidney cancer subtypes, chromophobe renal cell carcinomas (KICH) showed consistently and significantly reduced expression levels of CEBPZ, NOC2L and NOC3L (Fig. 4C), whereas other subtypes, such as KIRC (clear cell) and KIRP (papillary), displayed more variable expression patterns (Fig. 4D,E).
