Abstract excerpt
Autosomal dominant polycystic kidney disease is characterized by cyst formation in the kidney and other organs and results from mutations of PKD1 or PKD2. Previous studies suggest that their gene products have an important role in growth regulation. We now show that expression of polycystin-1 activates the JAK-STAT pathway, thereby upregulating p21(waf1) and inducing cell cycle arrest in G0/G1. This process...
