Glycitein is an O-methylated isoflavone which accounts for 5-10% of the total isoflavones in soy food products. Cell proliferation studies on the dietary phytoestrogen, glycitein against human breast carcinoma SKBR-3 cells showed that glycitein exhibits biphasic regulation on SKBR-3 cells. At
Metastasis is a major cause of morbidity and mortality in breast cancer with tumour cell invasion playing a crucial role in the metastatic process. The effects of a panel of phytoestrogens, including isoflavones and lignans on the invasion of a breast cancer cell-line (MDA-MB-231) through Matrigel
The scientific literature contains evidence suggesting that women who have been treated for breast cancer may, as a result of their diagnosis, increase their phyto-oestrogen (PE) intake. In the present paper, we describe the creation of a dietary analysis database (based on Dietplan6) for the
BACKGROUND
Phytoestrogens are a group of compounds found in plants that structurally resemble the hormone oestradiol, and thus have the potential to act as oestrogen agonists or antagonists. Their potential effects may alter the risk of breast cancer, but only a limited range of phytoestrogens has
High consumption of soy products in some Asian countries has been linked to the low incidence of breast cancer in women. The chemopreventive effect of the soy isoflavone, genistein, has been observed through the suppression of cell proliferation, inhibition of angiogenesis and stimulation of
A variety of health benefits, including protection against breast cancer, have been attributed to soy food consumption, primarily because of the soybean isoflavones (genistein, daidzein, glycitein). Isoflavones are considered to be possible selective estrogen receptor modulators but possess
BACKGROUND
Epidemiological studies have associated estrogen replacement therapy with a lower risk of developing Alzheimer's disease, but a higher risk of developing breast cancer and certain cardiovascular disorders. The neuroprotective effect of estrogen prompted us to determine potential
Consumption of soybean products has been implicated in the prevention of breast cancer. This study provides insights into the anti-proliferative activity of 12 anticarcinogens from soybean by single or two-way combination treatment against MCF-7 and MDA-MB-231 human breast cancer cells. Results
Subjects of this study consisted of 333 women (aged 45-75 years) drawn from a large United Kingdom prospective study of diet and cancer, the European Prospective Investigation of Cancer and Nutrition-Norfolk study. Using newly developed gas chromatography/mass spectrometry and liquid
OBJECTIVE
Phytoestrogens are plant compounds that are structurally and functionally similar to mammalian estrogens. By competing for estrogen receptors, phytoestrogens possibly inhibit binding of the more potent endogenous estrogens and decrease their potential effects on breast cancer risk. We
Glycitein is an isoflavone that reportedly inhibits the proliferation of human breast cancer and prostate cancer cells. However, its anti-cancer molecular mechanisms in human gastric cancer remain to be defined. This study evaluated the antitumor effects of glycitein on human gastric cancer cells
Phytoestrogens have attracted attention as being safer alternatives to hormone replacement therapy (HRT) and as chemopreventive reagents for breast cancer because dietary soy isoflavone intake has been correlated with reduction in risk. To identify safe and effective phytoestrogen candidates for HRT
Isoflavonoids are a group of biologically active phytochemicals that humans are exposed to mainly through soy food intake. Because of the similar chemical structure of these compounds and estradiol, it has been hypothesized that isoflavonoids may be related to the risk of breast cancer. Overnight
The development and validation of a bioanalytical assay is described for the simultaneous analysis in human serum of tamoxifen, four of its main metabolites and three flavonoids, which are known constituents in alternative medicine and dietary supplements often used by breast cancer patients. The
The use of phytoestrogens-containing natural sources as alternative hormone replacement therapy (HRT) has been a subject of debate for decades. Development of assays to characterize these phytoestrogens is required. In this study, differential estrogenicities of five isoflavonoids found in red
