Gene Expression upon Proliferation and Differentiation of Hematopoietic Cells with Ph Chromosome ex vivo.

ABSTRACT: The genesp53, mdm2, p21, c-myc,bcr/abl, bcr, bcl2, bax, and gapdh participate in the regulation of cell proliferation and differentiation, apoptosis and cell distribution for the cell cycle ex vivo in the Ph(+)cells of chronic myeloid leukemia containing the Ph chromosome andbcr/abloncogene. Expression of these genes correlates with regulation of cell proliferation and differentiation by alternating proliferation and maturation stages for three main Ph+cell types that occur under chronic myeloid leukemia. Thep53, p21, mdm2, and gapdh genes overexpress in active proliferating myeloid cells in the cell cycle S+ G2/M phases and when the phases are coincident with the proliferation stage. Expression of these genes decreases to a considerable level under alternation of the Ph(+)cell proliferati
