Herrington, David M., and Karen Potvin Klein. Pharmacogenetics of estrogen replacement therapy. J Appl Physiol 91: 2776–2784, 2001.— There are a number of genetic factors that likely modulate both the beneficial and adverse effects of estrogen. An important domain of consideration is the relationship of estrogen and thrombosis risk. Gene polymorphisms among the key elements of the coagulation a...

We report the fasting and post-challenge plasma insulin and glucose levels in 469 nondiabetic postmenopausal women from the Rancho Bernardo cohort according to the current use of estrogen replacement therapy. In these older women, the use of noncontraceptive estrogen was not associated with impaired glucose tolerance. Estrogen-treated women had lower levels of insulin than women who were not ta...

1. Epidemiological and clinical studies suggest that women may obtain cognitive benefits from oestrogen-replacement therapy (ERT) during menopause transition rather than in the post-menopausal stages. However, the underlying mechanisms remain to be determined. 2. We propose that long-term oestrogen deficiency may result in abnormal distribution and localization of brain oestrogen receptors, bra...

To determine whether mononuclear cell secretory products contribute to the changes in bone turnover that characterize the development of postmenopausal osteoporosis, we evaluated the effects of oophorectomy and subsequent estrogen replacement on the spontaneous secretion of interleukin 1 (IL-1) and tumor necrosis factor alpha (TNF-alpha) and on the phytohemagglutinin A-induced secretion of gran...

in addition to its effect on reproductive organs, estrogen exhibits complex effects on brain structure, function and behavior. in this regard, the influence of gonadal hormones especially estrogens on nociception has recently been accepted. soybean is known as an important phytoestrogen containing plant that is used as an alternative for estrogen replacement therapy. in this study, the influenc...

The complex role of the renin-angiotensin-system (RAS) in arterial pressure regulation has been well documented. Recently, we demonstrated that chronic low-dose angiotensin II (ANG II) infusion decreases arterial pressure in female rats via an AT(2)R-mediated mechanism. Estrogen can differentially regulate components of the RAS and is known to influence arterial pressure regulation. We hypothes...

Aging is associated with structural and functional changes in the vasculature, including endothelial dysfunction, arterial stiffening and remodeling, impaired angiogenesis, and defective vascular repair, and with increased prevalence of atherosclerosis. Cardiovascular risk is similar for older men and women, but lower in women during their fertile years. This age- and sex-related difference poi...

Background. Postmenopausal estrogen replacement therapy has been associated with favorable levels of cardiovascular disease risk factors, but these associations and the relations between estrogen use and subclinical disease have not been examined in large samples of older women. Methods and Results. Present and past estrogen use was ascertained in 2955 women .65 years old in the Cardiovascular ...

Estrogens are commonly used in gynecologic area, such as oral contraception, hormone replacement therapy, and in vitro fertilization-embryo transfer. Although estrogen is a common cause of acute drug-induced pancreatitis, there has been paucity of report in Korea. Clinical course of estrogen-induced acute pancreatitis is usually mild to moderate, but fetal case can occur. In addition, there can...

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...
