ZNF24 and nonpapillary renal cell carcinoma: To further validate these findings, we performed immunohistochemical staining for YOD1 and ZNF24 in a tumor microarray for ccRCC (cohort 1) (Fig. 8E), which consisted of 80 paired tumor and normal tissue samples and an additional 110 surgical tumor samples (cohort 2) (Fig. 8F).
