Estrogen has a biphasic effect on growth, stimulatory at low doses but inhibitory at higher doses. Therefore, designing optimal sex hormone replacement treatment in girls with Turner syndrome (TS) who are being treated with growth hormone (GH) involves considering the dose and form of the estrogen as well as the route and timing of its administration. We report here a preliminary analysis of a ...

OBJECTIVE To determine whether estrogen replacement therapy (ERT) adversely affected outcome of breast cancer survivors. METHOD A prospective descriptive study of all breast cancer survivors who requested ERT because of intractable menopausal symptoms. All patients presented voluntarily as gynecological outpatients and were all given oral continuous opposed ERT: 20 premarin and medroxyprogest...

OBJECTIVE Estrogen replacement therapy (ERT) ameliorates symptoms in postmenopausal women with syndrome X. We hypothesized that estrogen deprivation and replacement may modulate coronary expressions of angiogenic molecules, thereby modifying the coronary capillary network in perimenopausal women. METHODS AND RESULTS Middle-aged (40-week-old) female rats were subjected to sham surgery, ovariec...

10.2217/14750708.4.3.349 © 2 Up to 40%of postmenopausal women have symptoms of atrophic vaginitis. Since the condition is attributable to estrogen deficiency, it may also occur in premenopausal women who take antiestrogenic medications or who have medical or surgical conditions that result in decreased levels of estrogen. The thinned vaginal epithelium and increased vaginal pH level induced by ...

Spinal cord injury (SCI) always occurs accidently and leads to motor dysfunction because of biochemical and pathological events. Estrogen has been shown to be neuroprotective against SCI through estrogen receptors (ERs), but the underlying mechanisms have not been fully elucidated. In the present study, we investigated the role of a newly found membrane ER, G protein-coupled estrogen receptor 1...

OBJECTIVES To determine if low-dose estrogen replacement can be added to GnRH agonist therapy after three months to reduce hypoestrogenic symptoms while allowing continued relief of pain in patients with endometriosis. MATERIALS AND METHODS Thirteen women with endometriosis and pain were treated with six months of leuprolide acetate in a prospective, randomized double-blind placebo controlled...

Estrogen replacement therapy is cardioprotective in postmenopausal women; however, the precise molecular mechanisms for this modulation are not fully elucidated. We previously showed that chronic estrogen replacement therapy reduced angiotensin-converting enzyme (ACE) activity in tissue extracts and serum with an associated reduction in plasma angiotensin II. A reverse transcriptase-polymerase ...

Estrogen has been postulated as a contributor for lung cancer development and progression. We reviewed the current knowledge about the expression and prognostic implications of the estrogen receptors (ER) in lung cancer, the effect and signaling pathway of estrogen on lung cancer, the hormone replacement therapy and lung cancer risk and survival, the mechanistic relationship between the ER and ...

Estrogen regulation of myocardial chymase and chymase effects on cardiac remodeling are unknown. To test the hypothesis that estrogen prevents pressure overload-induced adverse cardiac remodeling by inhibiting mast cell (MC) chymase release, transverse aortic constriction or sham surgery was performed in 7-week-old intact and ovariectomized (OVX) rats. Three days before creating the constrictio...
