Induction of NQO1 in cancer cells.
Publisher Summary This chapter focuses on induction of NAD[P]H:[quinone acceptor]oxidoreductase (NQO1) in cancer cells. NQO1 is a flavoenzyme that catalyzes obligatory two-electron reduction ofExpand

Role of NADPH cytochrome P450 reductase in activation of RH1
PurposeRH1 is a new bioreductive agent that is an excellent substrate for the two-electron reducing enzyme, NAD(P)H quinone oxidoreductase 1 (NQO1). RH1 may be an effective NQO1-directed antitumorExpand

Expression of p53 predicts treatment failure in aggressive non-Hodgkin's lymphomas.
Approximately 50% of patients with aggressive non-Hodgkin's lymphomas (NHL) achieve a complete remission (CR) and cure with combination chemotherapy. The International Index is a useful clinicalExpand

Quinone-induced DNA damage and its relationship to antitumor activity in L5178Y lymphoblasts.
The presence of a quinone group in the structure of a series of model compounds was shown to produce cell kill by a mechanism involving free radicals and active oxygen species. Furthermore, theExpand

Evidence for carrier-mediated transport of melphalan by L5178Y lymphoblasts in vitro.
Mechanism of transport of the alkylating agent [14C]melphalan was investigated in L5178Y lymphoblasts in vitro. A time course of melphalan uptake was approximately linear for 5 to 10 min andExpand
