| Research Abstract |
Invadopodia are membrane protrusions formed by invasive cancer cells that mediate degradation of pericellular ECM and have been implicated in local invasion during cancer metastasis. In this study, we investigated the role of phosphoinositide metabolism in invadopodium formation. We found that PI3 kinase p110α, a frequently mutated gene product in human cancers, is involved in invadopodium formation and invasion by breast cancer cells. This finding suggests that the signaling pathway via p110α is a potential therapeutic target for the treatment of cancer invasion and metastasis.
