Acute Responses To Estradiol Replacement In The Olfactory System Of Apoe-Deficient And Wild-Type Mice, Britto P. Nathan, Michael Tonsor, Robert G. Struble
Acute Responses To Estradiol Replacement In The Olfactory System Of Apoe-Deficient And Wild-Type Mice, Britto P. Nathan, Michael Tonsor, Robert G. Struble
Britto P. Nathan
Epidemiological studies suggest that estrogen therapy protects against clinical expression of chronic neurological diseases. These beneficial effects of estrogen therapy are highly modified by apolipoprotein E (apoE) through an unknown mechanism. We examined the short-term effects of estradiol replacement in ovariectomized mice on apoE expression and markers for cell proliferation, reactive gliosis, neuronal maturation, and synaptogenesis in the primary olfactory pathway of wild-type (WT) and apoE knockout (KO) mice. Three days of estradiol replacement increased apoE expression in the olfactory nerve and in the glomerular layer. Estradiol treatment also increased cell proliferation, total cell numbers, number of mature neurons in …

The supraspinal control of descending inhibition of genital reflexes (such as ejaculation) is poorly understood but is important in our global comprehension of how neural signals are integrated to produce sexual behavior, and in our understanding of sexual dysfunction. Sexual dysfunctions, such as premature ejaculation/delayed ejaculation in men, and involuntary vaginal spasms, dyspareunia, and anorgasmia in women, are common. An underlying dysregulation of genital reflexes may produce these dysfunctions, especially in those individuals being treated for depression and anxiety with serotonergic drugs. The nucleus paragigantocellularis (nPGi) of the rat medulla has been described as a descending inhibitory system for genital …

Previous studies on MCF-7 breast cancer cells have shown that the G-protein coupled receptor (GPCR) agonist carbachol increases intracellular calcium levels and the activation of extracellular signal-regulated kinase (ERK). Calcium and calmodulin regulate the calcium/calmodulin- dependent kinase (CaM kinase) family of proteins that have been proposed to regulate ERK and gene transcription. Our results suggest that both estrogen (E2) and carbachol treatment of MCF-7 breast cancer cells trigger phosphorylation of ERK I /2 and the transcription factor Elk-1. Carbachol and estrogen triggered nearly a four- to sixfold increase in MCF-7 cell proliferation by 96 h, respectively. Carbachol-stimulated ERK activation and …
