| Research Abstract |
We have investigated exocytotic release of ATP from urothelium, especially focusing on vesicular nucleotide transporter (VNUT). VNUT gene and protein was highly expressed in the epithelial layer of mouse bladder tissue and primary urothelial cell culture. The stretch-evoked ATP release was significantly reduced by the treatment of VNUT siRNA or several inhibitors of vesicular exocytosis. These findings suggest that VNUT plays an important role in stretch-elicited ATP release from urothelium.
