Abstract

Alterations of antioxidant enzyme activities have been described in a number of psychiatric disorders including major depression. Subsequently, the present study examined the effects of different types of antidepressants (desipramine, imipramine, maprotiline and mirtazapine) in different concentrations (10(-5), 10(-6) and 10(-7) M) on the mRNA levels of various enzymes of the antioxidant system, including both intracellular superoxide dismutase isoforms, glutathione peroxidase and catalase as well as several enzymes of the glutathione metabolism in monocytic U-937 cells after short- and long-term treatment (2.5 and 24 h) via RT-PCR. Results indicated mainly short-term decreases in the mRNA levels of antioxidant enzymes after treatment with these substances in all the concentrations used. In addition, after long-term treatment, significant increases in the mRNA levels were seen in the cases of Cu, Zn superoxide dismutase, gamma-glutamyl-cysteine synthetase, glutathione-S-transferase and glutathione reductase, including the impacts of all the antidepressants used in concentrations of 10(-6) M and 10(-7) M. Based on the large number of significant effects of all types of antidepressants tested on various antioxidant enzymes, we suggest that antioxidant enzymes may represent important targets in the course of antidepressive treatment.

About these checks

Registry, retraction, Cites and statistics results are computed, not judged, with one exception: a printed reference that no index lists is read once by a model before it counts as a citation error. Claims are extracted by a model and kept only when their quote appears verbatim in the text; each cited source is then checked, with a model’s help, for whether it says what the claim relies on. Those verdicts can be wrong — read the claim’s quote and the cited source before relying on one.

Statistics and arithmetic are recomputed, not judged.

Confidence bands are shown only for fields calibrated on our annotated test set. None is calibrated yet, so no band is shown.
