The present inventio relats treatment of tumors using a Bax protein fragment to induce apoptosis. More specifically, the present invention relates to the use of the Bax amino terminus 18kDa fragment to induce cytochrome c release and apoptosis in cancer cells. Further provided is the method of inducing cell death even in cancer cells overexpressing Bcl-2 oncoprotein. Further provided is a method using Bax/p18 of triggering cytochrome c release, activation of caspase-3, cleavage of poly(ADP-ribose) polymerase, fragmentation of DNA and induction of cell death. Further provided is a method of introducing Bax/p18 protein into a cancer cell via introducing Bax/p18 cDNA, to cause release of cytochrome c and induction of caspase-3 mediated apoptosis that is not blocked by overexpression of Bcl-2. |
