Abstract
Disclosed is a novel composition and method for chemotherapy in leukemia. Activation of the calcium ion channel by tipifarnib increases intracellular calcium and triggers cell death in leukemia cell lines. Increasing the activity of this channel with 2-aminoethoxydiphenyl borate (2-APB) enhances both the intracellular calcium elevations and cell death, whereas decreasing the activity of the channel with gadolinium or lanthanum blocks the calcium increases and promotes cell survival. The protein target was able to overcome cell adhesion-mediated drug resistance, which often limits the usefulness of other targets. This protein is expressed in other immortalized cell lines, but has limited expression in normal native cell types in humans. Such limited expression would reduce the likelihood of adverse side effects associated with the targeting of this protein.
