We evaluated the expression of basal markers (cytokeratin (Ck) 5, p63), luminal markers (Ck8, Ck20), a tumor initiating marker (CD44), a proliferating marker (Ki67), and urothelial carcinoma markers (GATA3, uroplakin II (UPKII) (Figure 1D; Figure S2, Supporting Information). The gene discussed is KRT8; the disease is urothelial carcinoma.
