Adult female rats were ovariectomized and received a 21-day release pellet containing either (17)beta-estradiol (0.1 mg), tamoxifen (5.0 mg), a combination of estradiol and tamoxifen or no further treatment. At 14 days following ovariectomy +/-…
The secretion of growth hormone (GH) is impaired in the genetically obese Zucker rat where GH gene expression and plasma GH levels are depressed; however, the underlying mechanism of this abnormality remains unclear. We have evaluated the potential…
Estrogen increases methamphetamine (MA)-induced neurotoxicity within the impaired nigrostriatal dopaminergic (NSDA) system of ovariectomized female mice, as defined by enhanced striatal dopamine (DA) depletion. In this study we compared the effects…
Sex differences are reported for methamphetamine (MA)-induced neurotoxicity of the nigrostriatal dopaminergic system. In an attempt to understand some of the bases for these differences, we investigated MA-evoked dopamine (DA) responses from…
In the present experiment we evaluated the dose-response effects of estrogen (estradiol benzoate; EB) and tamoxifen (TMX) in modulating the acute behavioral and chronic effects of methamphetamine (MA) upon the nigrostriatal dopaminergic (NSDA) system…
In this report female and male CD-1 mice were treated with a neurotoxic regimen of methamphetamine (MA) to compare gender differences in striatal dopamine depletion and concordant changes in mRNA markers of the transforming growth factor-beta injury…
