Outline of Final Research Achievements |
The effect of focal mechanical stress on the localization of TRPV2 was investigated in HT1080 cells. When focal mechanical stress was applied, subplasma membrane Ca2+ concentration ([Ca2+]s) was increased beneath the pipette, which propagated throughout the cell. The increase in [Ca2+]s was blocked by knocking down TRPV2. The focal mechanical stress induced vinculin conformation change was blocked by knocking down TRPV2. Elevation of [Ca2+]s was not observed by the application of Gd3+ and mechanical stress induced accumulation of TRPV2 -GFP beneath the pipette was not observed.
