| Research Abstract |
The proto-oncogene product c-Src is highly upregulated in various cancer cells. Src function is downregulated in the lipid rafts, indicating the lipid rafts serve as a negative regulator of activated c-Src. However, it has not been known how lipid rafts are altered during c-Src-induced cancer progression. In this study, we newly revealed that raft-localization of c-Src is regulated by lipid metabolism and that inhibition of lipid alteration suppresses c-Src-induced cell transformation. Taken together, Src regulates raft integrity by alteration of lipid metabolism for maintaining c-Src activation.
