| abstractText | NAD(P)H:quinone oxidoreductase 1(-/-) (NQO1(-/-)), NQO1(+/-) along with NRH:quinone oxidoreductase 2(-/-) (NQO2(-/-)), and wild-type (WT) mice were exposed to five once weekly doses of mitomycin C. The mice were euthanized 15 weeks after the first dose. Blood cell counts and histologic analyses were done. WT and NQO2(-/-) mice showed hypocellularity and a significant increase in adipocytes in bone marrow. They also showed anemia because of the loss of RBC and hemoglobin. The neutrophils and platelets were reduced, whereas other blood cell types and tissues were normal. Interestingly, NQO1(-/-) mice showed a complete resistance to mitomycin C-induced bone marrow cytotoxicity and reduction in RBC, hemoglobin, and neutrophils. NQO1(+/-) mice also showed limited resistance to mitomycin C-induced bone marrow cytotoxicity. These data show a major in vivo role of NQO1 in metabolic activation of mitomycin C with implications in mitomycin C chemotherapy. [Cancer Res 2007;67(17):7966-71]. |
