Control of Growth and Differentiation of Philadelphia Chromosome-Positive Leukemia Cells by Tyrosine Kinase Inhibitors

Abstract

HONMA, Y., KASUKABE, T, and HOZUMI, M. Control of Growth and Differentiation of Philadelphia Chromosome-Positive Leukemia Cells by Tyrosine Kinase Inhibitors. Tohoku J. Exp. Med., 1992, 168 (2), 387-391- Herbimycin A, a selective inhibitor of tyrosine kinase activity, induced differentiation of leukemia cells isolated from Philadelphia chromosome-positive chronic myelogenous leukemia patients. However, it did not induce differentiation of leukemia cells from acute myelogenous leukemia patients, although these cells could be induced to differentiate by treatment with appropriate compounds. A selective inhibitor of tyrosine kinase might be useful in chemotherapy of Philadelphia chromosome-positive leukemia.- Philadelphia chromosome-positive leukemia; acute myelogenous leukemia; chronic myelogenous leukemia; herbimycin A; tyrosine kinase inhibitor
