제목 Apoptosis-inducing polypeptide via mitochondrial destabilization and malfunction
초록 Cationic α-helical polypeptides have exhibited a high cell-penetrating ability and have generally been used as cell-penetrating peptides to deliver drugs or genes into cells. Mitochondria play a important role in inducing apoptosis in cells. In this context, we have developed a mitochondrial destabilizing polypeptide (MDP) using the cell-penetrating capability of cationic α-helical polypeptides. In order to confer mitochondrial-destabilizing ability to induce apoptosis of MDP, the lipophilic cation moiety was attached as a pendant to the side chain of the polypeptide. MDP showed high α-helical properties required for cell permeability and mitochondrial-destabilizing ability. MDP also showed an unprecedented high cytotoxicity and apoptotic signal in various cancer cell lines. MDP is likely to be applied in a variety of studies on cancer therapy in relation to unprecedented high mitochondrial-destabilizing capacity.
