Clinical Significance:
Uroplakin III is present in the urothelial surface membrane of human renal pelvis, ureter, bladder and urethra. It is highly specific to uroepithelial tumors and may be a useful tool in the discrimination of bladder, renal and prostate cancers. Loss of Uroplakin III expression in bladder cancers has been associated with higher grade, muscle-invasive cancer and lymphovascular invasion.
