The induction of phase 2 detoxifying enzymes, such as UDP-glucurono-syltransferases (UGTs), in response to an array of naturally occurring and synthetic agents, such as oltipraz (4-methyl-5-[2-pyrazinyl]-1,2-dithiole-3-thione), provides an effective means of protection against a variety of carcinogens. Transcription factor Nrf2 is an essential regulator of(More)
Nuclear factor-erythroid 2 (NF-E2)-related factor 2 (Nrf2), a transcription factor that regulates inducible expression of detoxifying enzymes, is critical in preventing N-nitrosobutyl(4-hydroxybutyl)amine (BBN)-induced urinary bladder carcinogenesis. To explore whether Nrf2 and the tumor suppressor p53 cooperatively act in tumor prevention, we investigated(More)
PURPOSE We have previously demonstrated that the AgNOR count in proliferating cells is a predictor of tumor recurrence in superficial bladder tumor (J. Urol. 162 (1999), 63-68). In the present study, we evaluate the type of AgNOR associated with cell cycles as a prognostic factor in invasive bladder tumor using a double staining technique employing both(More)
