[Alteration of CD38 expression and NAD+ metabolism induced by Doxorubicin in bone marrow cells].
Mechanisms of myelotoxic action of Doxorubicin associated with changes in NAD(+)-glycohydrolase/CD38 expression and activity have been assessed. During the acute and subacute exposure of bone marrow cells to Doxorubicin in vivo, expression of CD38 is decreased corresponding to elevation of intracellular and extracellular NAD+ concentrations. These changes are associated with increased susceptibility of hemopoietic cells to the apoptogenic action of Doxorubicin. Possible role of NAD(+)-glycohydrolase/CD38 in the regulation of sensitivity of the cells to the cytotoxic effects of the xenobiotic is discussed.
