Gender differences in genetic mouse models evaluated for depressive-like and antidepressant behavior.
Journal Title: Pharmacological Reports - Year 2013, Vol 65, Issue 6
Abstract
Depression is a mental disease that affects complex cognitive and emotional functions. It is believed that depression is twice as prevalent in women as in men. This phenomenon may influence the response to various antidepressant therapies, and these differences are still underestimated in clinical treatment. Nevertheless, most of the current findings are based on studies on male animal models, and relatively few of these studies take possible gender differences into consideration. Advancements in genetic engineering over the last two decades have introduced many transgenic lines that have been screened to study the pathomechanisms of depression. In this mini-review, we provide a compendious list of genetically altered mice that underwent tests for depressive-like or antidepressant behavior and determine if and how the gender factor was analyzed in their evaluation. Furthermore, we compile the gender differences in response to antidepressant treatment. On the basis of these analyses, we conclude that in many cases, gender variability is neglected or not taken into consideration in the presented results. We note the necessity of discussing this issue in the phenotypic characterization of transgenic mice, which seems to be particularly important while modeling mental diseases.

NMDA and AMPA receptors are involved in the antidepressant-like activity of tianeptine in the forced swim test in mice.
It is known that tianeptine exhibits antidepressant-like activity. Its influence on the glutamatergic system is also known, but the mechanisms involved in this activity remain to be established. The aim of this study was...
Role of endothelin-1 receptor blockers on hemodynamic parameters and oxidative stress.
Endothelin (ET) was first isolated and described by Yanagisawa et al. and has since been described as one of the most potent known vasoconstrictor compounds. ET-1 mediates its effects via two types of receptors, ETA and...
Influence of acute and subchronic oral administration of dehydroepiandrosterone (DHEA) on nociceptive threshold in rats.
Background: Dehydroepiandrosterone (DHEA), a neurosteroid, is known to be the most abundant hormone in the human body. Its role in the central nervous system has not been well defined. Previous studies indicate that DHEA...
Role of nitric oxide, nitroxidative and oxidative stress in wound healing.
Redox-regulated processes are relevant to wound healing. A balance between bioavailable nitric oxide (NO) concentration and a level of oxidative and nitroxidative stress in wounds may be crucial in wound repair. The high...
Effect of chronic apocynin treatment on nitric oxide and reactive oxygen species production in borderline and spontaneous hypertension.
The purpose of this study was to investigate the effect of NAD(P)H oxidase inhibitor - apocynin (4-hydroxy-3-methoxyacetophenone) on the increase of systolic blood pressure (SBP) in borderline (BHR) and spontaneously hyp...
