Soybean seeds contain large amounts of isoflavones or phytoestrogens such as genistein, daidzein, and glycitein that display biological effects when ingested by humans and animals. In seeds, the total amount, and amount of each type, of isoflavone varies by 5 fold between cultivars and locations. Isoflavone content and quality are one key to the biological effects of soy foods, dietary suppleme...

Phytoestrogens, plant-derived nonsteroidal estrogens found in high abundance in most soy food products, have been studied for their potential beneficial effects against hormone-dependent cancers and age-related diseases. However, little is known about the influence of phytoestrogens on the brain or behavior. This brief review describes mainly our own studies in rodents that have examined the in...

Shemesh, M. and Shore, L.S. 6 INTRODUCTION The present review describes a number of environmentally caused reproductive disorders in domestic animals which we have observed over the last five decades. This is of interest not only for animal husbandry but these environmental hormones may responsible for human health effects as well. However effects of phytoestrogens or other naturally occuring e...

Phytoestrogens are naturally occurring compounds that have similar molecular structure to estrogen hence able exert estrogenic activities by binding receptors (ERs), ERα and ERβ. been reported suppress cancer cell survival growth in various types of cancers including lung cancer, breast prostate cancer. Moreover, phytoestrogens shown inhibit migration invasion targeting multiple pathways. These...

INTRODUCTION Phytoestrogen genistein may be useful to treat pulmonary arterial hypertension (PAH). However, its mechanism is still not clear. The aim of the present study was to confirm the therapeutic effects of phytoestrogen genistein on PAH in monocrotaline-induced rat model and to explore its mechanism. MATERIALS AND METHODS Sprague-Dawley male rats were randomly divided into 4 groups: co...

Abstract Resveratrol obtained in grape seed and skin is structurally similar to a synthetic estrogen diethylstilbestrol. The endogenous estrogen, 17β-estradiol, induces cellular responses by binding the receptor alpha beta. bone fracture due decreased mineral density postmenopausal women linked reduced estrogen. adverse drug reactions of hormone replacement therapy warrant identifying unique na...

Worldwide, breast cancer is the most common malignant neoplasm and the second most common cause of cancer death in women. This malignancy is recognized to be estrogen-dependent and due to this feature, hormone replacement therapy is regarded as potentially dangerous in breast cancer survivors who seek relief of their menopausal symptoms. Whereas hot flashes are detected in nearly half of postme...

Wild-type erbB-2/neu transgenic mice were used to study the interactions between tamoxifen and dietary phytoestrogens (or isoflavones) by dose and form in vivo. Mice were randomized to one of four dietary formulas and implanted with an 8-week continuous-release tamoxifen or placebo pellet at 8 weeks of age. In placebo-treated mice, soy meal diet (but not diets supplemented with low-dose or high...

Despite their unrivalled value in livestock systems, certain temperate, pasture, legume species and varieties may contain phytoestrogens which can lower flock/herd fertility. Such compounds, whose chemical structure and biological activity resembles that of estradiol-17α, include the isoflavones that have caused devastating effects (some of them permanent) on the fertility of many Australian sh...
