On the contrary, the CD161 expression was decreased in tumor tissues than in normal tissues in upper tract urothelial cancer (UTUC) and micropapillary urothelial carcinoma (MPUC; Figure 8G), BLCA (Figure 8H), and penile squamous cell carcinoma (PSCC; Figure 8I). This evidence concerns the gene KLRB1 and micropapillary urothelial carcinoma.
