Research has shown that obesity increases the risk for type 2 diabetes mellitus (Type DM) by promoting insulin resistance, serum estrogen levels upregulation of aromatase, and promotes release reactive oxygen species (ROS) macrophages. Increased circulating glucose been to activate mammalian target rapamycin (mTOR), a significant signaling pathway in breast cancer pathogenesis. Estrogen plays a...

BACKGROUND In a university hospital setting, a 25-year-old woman presented with large vaginal and cervical polyps. Past medical history was significant for stage IV endometriosis. Polypectomy was performed and the polyps were histologically consistent with endometriosis. Gene expression was compared with control vaginal tissue to assess if the altered gene expression profile was similar to peri...

OBJECTIVE Local estrogens are used for the treatment of genitourinary symptoms of menopause. The efficacy and adverse effects of both estrogen-containing vaginal tablets (VT) and estrogen-containing vaginal creams (VC)/gels are comparable. Our objective was to assess the compliance and adherence to treatment in a large population. METHODS A retrospective study on women aged 40 to 89 was perfo...

A major question in transcription factor (TF) biology is why a TF binds to only a small fraction of motif eligible binding sites in the genome. Using the estrogen receptor-α as a model system, we sought to explicitly define parameters that determine TF-binding site selection. By examining 12 genetic and epigenetic parameters, we find that an energetically favorable estrogen response element (ER...

Attention-deficit/hyperactivity disorder (AD/HD) is a common pediatric behavioral disorder associated, in part, with male preponderance and reduced regional cerebral blood flow (rCBF). However, mechanism(s) underlying male preponderance and reduced rCBF in AD/HD are unclear. The present study profiles the expression of angiogenic and hormonal factors likely to underlie these symptoms using a re...

Estrogen stimulation of the medial amygdala (MEA) of the brain promotes male rat mating behavior. However, selective stimulation of either of the estrogen receptor subtypes found in the MEA (ERα or ERβ) does not support mating behavior. We tested the hypothesis that dual stimulation of ERα and ERβ is required to activate estrogen-dependant neural circuits in the MEA responsible for mating by lo...

Considerable research has been devoted to the understanding of how nitric oxide (NO) influences brain function. Few studies, however, have addressed how its production is physiologically regulated. Here, we report that protein-protein interactions between neuronal NO synthase (nNOS) and glutamate NMDA receptors via the scaffolding protein postsynaptic density-95 (PSD-95) in the hypothalamic pre...

Gender has been shown to impact the prevalence of several lung diseases such as cancer, asthma, chronic obstructive pulmonary disease, and pulmonary arterial hypertension (PAH). Controversy over the protective effects of estrogen on the cardiopulmonary system should be of no surprise as clinical trials of hormone replacement therapy have failed to show benefits observed in experimental models. ...

Experimental and population-based evidence has been steadily accumulating that steroid hormones are fundamentally involved in the biology of the lung. Both estrogen and progesterone receptors are present in normal and malignant lung tissue, and the reproductive hormones that bind these receptors have a role in lung development, lung inflammation, and lung cancer. The estrogen receptor-β (ER-β) ...

background: there are some controversial data on application of progesterone and progesterone plus estrogen at luteal phase. objective: to investigate the effects of different luteal support hormones on the alkaline phosphates (alp) activity in the endometrial epithelium and endometrial thickness during superovulation process for obtaining the optimized endometrial receptivity in animal model. ...
