We examined the effects of diquat (0.1 mmol/kg, ip) and ciprofibrate (0.025% w/w, diet), chemicals which induce oxidative stress via different biochemical mechanisms, on the steady-state messenger RNA (mRNA) levels of six cytochrome P450 enzymes, seven glutathione S-transferase (GST) isoenzymes, UDP-glucuronosyl transferase 1-06 (UGT1*06), gamma-glutamylcysteine synthetase (gamma GCS), NADP (H):quinone oxidoreductase (quinone reductase), Cu/Zn superoxide dismutase (SOD), catalase, and 18S ribosomal RNA in the livers of male Sprague-Dawley rats.

The possibility that diquat increased transcription by transfecting cells with a chimeric gene containing 935 bp of the G6PDH promoter (-878 to +57) linked to the gene for chloramphenicol acetyl-transferase (CAT) was examined.

To verify these findings in vivo, male Fisher rats were treated with diquat and menadione.
DNA strandbreaks, evaluated with the terminal deoxynucleotidyl transferase-mediated dUTP nick-end labeling (TUNEL) assay, showed clusters of TUNEL-positive cells, where the staining was predominantly cytosolic and the cells were swollen, indicating oncotic necrosis.

The present studies were to test the hypotheses that glutathione reductase (GR), glutathione peroxidase (GPX), and glutathione S-transferase (GST) activities are expressed in nuclei and nucleoli of rat liver cells, and that differences in activities of these enzymes would correlate with the greater resistance of female than of male Fischer-344 rats to hepatic necrosis in vivo, mediated by reactive oxygen species generated by redox-cycling metabolism of diquat.
