| 内容記述 | Aggressively invasive human oral squamous cell carcinoma cells as SAS-H1 have the ability to extend membrane protrusions, invadopodia, into the extracellular matrix . These structures are associated with sites of active matrix degradation. The amount of membrane protrusions has been shown to correlate directly with the invasive potential. Immunofluorescent staining using mAb phospatidylinositol 3-kinase (PI3-K) p85α shows that the P13-K p85 regulatory subunit is predominantly associated with invadopodia, coreresponding to the areas where fibronectin / gelatin degradation occurs. We demonstrate that PI3-K inhibitors (wortmannin and LY294002) blocks local extracellular matrix degradation and formation of invadopodia. The SAS-H1 cells were sheared from the surface of a gelatin matrix to isolate invadopodia. The PI3-K p85 regulatory subunit and PI3-K p110α catalytic subunit were co -immunoprecipitated as a complex from invadopodia by Western blotting. PI3-K activity was higher in the invadopodia fraction than in the cell body fraction. These findings suggest that PI3-K has a direct role in the regulation of invadopodia activity. | |||||
