Although the ovaries produce majority of estrogens in women before menopause, estrogen is also synthesized peripheral tissues such as adipose tissue (AT). The typical female AT distribution, concentrated subcutaneous and femoro-gluteal regions, estrogen-mediated, but significance synthesis premenopausal poorly understood. Serum visceral homogenates from 28 undergoing non-malignant surgery were ...
Phytoestrogens are polyphenolic non-steroidal plant compounds with estrogen like activity exerted through estrogen receptors. These receptors are distributed in several tissues such as male and female reproductive systems, bones, cardiovascular and central nervous systems. These natural phenolic compounds include isoflavonoids, flavonoids, lignans and stilbenes. Isoflavonoids are the most studi...
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: 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. ...
background: the effect of ovariectomy and accompanying sudden loss of circulating gonad hormones on spatial learning performance in the young adult rats was examined. we hypothesized that spatial learning and memory in a considerable number of women who undergo a surgical menopause and estrogen deprivation before their natural menopause be impaired. methods: in this study, we used 26 wistar rat...
background:estrogens play a substantial role in the proliferation, progression and treatment of breast cancer by binding with two estrogen receptors, alpha and beta (erα and erβ). resistance to endocrine therapy is a major problem in the treatment of breast cancers and, in some cases, may be related to loss of er gene expression. we have already showed that erα methylation occurs in high freque...
background and objective: angiogenesis is a complex program of several steps and it is tightly regulated by pro- and anti-angiogenic factors. angiogenesis is one of the key elements in cutaneous wound healing and skin cancers. estrogen seems to have positive modulating effect on cutaneous wound healing and this effect may be explained by its angiogenic properties. this study aims to investigate...
Background: Breast cancer is one of the most common cancers in women. Nearly 30% of breast cancers are hormone-dependent, and these hormones comprising estrogens influence progression of breast cancers. It is now widely recognized that p53 may be the most frequently mutated protein in breast cancer. High levels of p53 protein are a common feature of many human malignant cancers. Given that, T47...
Background: Endometrial carcinoma (EC) is the most common gynecologic malignancy however, mechanisms underlying its pathogenesis remain obscure. Endometrial carcinoma has been classified into two major categories: type I (related to estrogen or endometrioid adenocarcinoma) and type II (unrelated to estrogen). Estrogen is the main trigger for the abnormal proliferation in the endometrial epithel...
This study was conducted to see the effects of Clomiphene Citrate on fertility hormones estrogen, progesterone, LH, FSH in patients with infertility associated polycystic ovary syndrome. For this fifty infertile PCOS who were given treatment clomiphene citrate (50–150mg/day for 5 days). Ovarian response ovulation monitored by transvaginal ultrasonography and serum levels FSH, estrogen also esti...
