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.

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.

This study examined the response of 7-ethoxyresorufine-O-deethylase, glutathione-S-transferase, glutathione peroxidase, glutathione content, level of thiobarbituric acid reactive compounds and circulating vitellogenin, in three-spined sticklebacks after 21 days of exposure to Diquat herbicide, commercial nonylphenol polyethoxylate adjuvant and mixture between Diquat and adjuvant.

It causes a decrease in glutathione peroxidase activity, an increase in glutathione S-transferase activity, and an increase in the rate of glutathione synthesis.
Selenium-deficient rats are much more sensitive to diquat toxicity than are controls.

Hepatic activities of superoxide dismutase (SOD) and glutathione peroxidase (GPX) were similar in the two genders, and activities of glutathione reductase (GR) and glutathione S-transferase-alpha (GST-alpha) activities were higher in the male rats.
