Objective(s): Diabetes is a metabolic disease with an increasing prevalence for which finding new and efficient therapeutic approaches has always been a challenge. Preserving integrity and functionality of pancreatic β-cells as the only source of insulin in the body is such a case. To achieve this goal different cellular targets have been proposed among which pancreatic estrogen receptors have ...

We have recently identified the hADA3 protein, the human homologue of yeast transcriptional coactivator yADA3, as a novel HPV16 E6 target. Using ectopic expression approaches, we further demonstrated that hADA3 directly binds to the 9-cis retinoic acid receptors alpha and beta, and functions as a coactivator for retinoid receptor-mediated transcriptional activation. Here, we examined the role o...

background and objectives: breast cancer is the most common malignancy among women in the world. the aim of this study was to assess estrogen receptor (er), progesterone receptor (pr) and her-2/neu of infiltrating ductal carcinoma (idc) with tumor size, histologic grade, lymph node metastasis and age. methods: this study was carried out on 300 tissue blocks ofpatients with idc who underwent mas...

Estrogen is a crucial hormone in human physiology that regulates a multitude of biological processes. It is also an important target in many diseases such as cancer and skeletal, neurological and immunological conditions. The actions of estrogen have traditionally been ascribed to one of two closely related classical nuclear hormone receptors, ERalpha and ERbeta, which are best characterized fo...

Conjugated equine estrogen therapy is the most common hormone replacement strategy used to treat postmenopausal women. However, the ability of an individual conjugated equine estrogen to modulate NO production and, therefore, to induce cardiovascular protection is largely unknown. The effects of equine and naturally occurring estrogens on NO generation were evaluated in human aortic endothelial...

Spindle cell epitheliomas of the vagina (SCEVs) coexpresses epithelial and mesenchymal markers and were first described as a "mixed tumors of the vagina." However, unlike mixed tumors of other organs, which are believed to originate from myoepithelial cells, SCEVs neither immunohistochemically nor ultrastructurally show features of myoepithelial cells. The present expanded battery of immunohist...

Many biological and physiological events, including growth, development, metabolism of reproductive non-reproductive tissues in men women, are regulated by estrogens estrogen receptors (ERs) [...]

We have recently shown that estrogen negatively modulates the hypotensive effect of clonidine (mixed alpha2-/I1-receptor agonist) in female rats and implicates the cardiovascular autonomic control in this interaction. The present study investigated whether this effect of estrogen involves interaction with alpha2- and/or I1-receptors. Changes evoked by a single intraperitoneal injection of rilme...

BACKGROUND The importance of estrogen in regulation of fluid absorption and sperm maturation in the rodent epididymis has been established from studies on estrogen receptor-alpha knockout mice. However, functional studies on the role of estrogen in primate epididymis have been few. The main objective of this study was therefore to extend these observations and systematically analyze the presenc...
