Abstract

We examined alterations of lipid constituents induced by hybrid liposomes (HLs) in cancer cells. As early as 1 h after HL treatment, amounts of the raft/caveolae lipids sphingomyelin, ceramide, and ether-type PC were altered. In addition, the structures of caveolae on the cytoplasmic surface of the cell membrane were significantly changed. Our results suggest that alterations of lipid composition in caveolae mediate HL signaling for apoptosis.
