Urinary proteins with pro-apoptotic and antitumor activity.
Analysis of the protein composition of urine has been the subject of much research that has captured the interest of scientific groups over the years. A number of factors have been isolated from urine that possess anti-neoplastic activities as seen both in vitro and in vivo studies. The urine from pregnant women and commercial preparations of crude clinical grade human chorionic gonadotropin contain factors (HAF for hCG associated factor) with anti-Kaposi's sarcoma activity. Also found in urine with activity are eosinophil-derived neurotoxin (EDN), anti-neoplastic urinary protein (ANUP), inhibin, activin A, and angiostatin. The anti-cancer activity of urinary proteins is associated with apoptosis of endothelial cells and of tumor-associated endothelial cells. A better understanding of the biological functions of these various urinary proteins, and of others that remain to be discovered, should provide insights into novel cell regulatory systems operating during pregnancy.
