1 Daunorubicin activates NFkappaB and induces kappaB-dependent gene expression in HL-60 promyelocytic and Jurkat T lymphoma cells. Daunorubicin nuclear factor kappa B subunit 1 Homo sapiens
2 Since the generation of ceramide has been directly linked with the activation of the transcription factor, NFkappaB, this was investigated as a novel target for the action of daunorubicin. Daunorubicin nuclear factor kappa B subunit 1 Homo sapiens
3 Here we describe how treatment of HL-60 promyelocytes and Jurkat T lymphoma cells with daunorubicin results in the activation of the transcription factor NFkappaB. Daunorubicin nuclear factor kappa B subunit 1 Homo sapiens
4 Daunorubicin also induced IkappaB degradation and increased the expression of an NFkappaB-linked reporter gene. Daunorubicin nuclear factor kappa B subunit 1 Homo sapiens
5 These data therefore suggest that the effect of daunorubicin on NFkappaB is unlikely to involve ceramide, but may involve reactive oxygen species generated as a result of endogenous cellular processes rather than reductive metabolism of the drug. Daunorubicin nuclear factor kappa B subunit 1 Homo sapiens
