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
Crohn's disease (inflammatory bowel syndrome) is caused by gut exposure to harmful reactive oxygen species (ROS) derived from oxygen, such as the superoxide anion ((.)O(2)'), the hydroxyl radical ((.)OH) or the peroxide anion (O(2)''): the superoxide anion is generated by breakdown of
The effects of isoflavones and of a derivative of soybeans fermented with Bacillus subtilis, designated Nattoesse, on the lipopolysaccharide (LPS)-induced production of tumor necrosis factor-alpha (TNF-alpha) and fibrinolysis were investigated in vivo. The dietary supplement Nattoesse contains
BACKGROUND
Epidemiological studies have suggested that soybean isoflavones are associated with a lower risk of prostate cancer. However, the mechanisms of prostate cancer prevention by soybean isoflavones have yet to be fully clarified.
METHODS
Two soybean isoflavones (genistein and daidzein) and
Among many functional foods and their phytochemicals, ingestion of soybean (Glycine max) is highly correlated to reduced risk of cardiovascular diseases. Validation of potential health benefits of functional foods requires information about the bioavailability and metabolism of bioactive compounds.
The roles of isoflavones in the prevention of several hormone-dependent cancers and osteoporosis are of great interest. Despite many pharmacokinetics studies of the isoflavones, the actual types of conjugates circulating in the body and the position(s) of conjugation sites on the flavone skeleton
Commercial processing wastes or by-products of crops were found to be sources of antimutagens and human tumor cell growth suppressors. We developed a microplate method to measure genomic DNA damage in Chinese hamster ovary cells with a modified single cell gel electrophoresis (SCGE) assay. This
Cancer is the eventual outcome of the transformation of normal cells by DNA-reactive, genotoxic carcinogens and the growth promotion of mutated cells by enhancing factors. It is important to discriminate between genotoxic carcinogens and nongenotoxic chemicals because their mechanisms of action are
The potential interaction of daidzin, an ingredient of soy isoflavones, with human telomeric antiparallel G-quadruplex dAG(3)(T(2)AG(3))(3) was studied using ESI-MS, PAGE, CD and molecular simulation. Experimental studies indicated that daidzin molecules interacted with dAG(3)(T(2)AG(3))(3) and
The in vitro anti-tumor promoting effect of hypocotyls from fresh soybeans was evaluated. The dimethyl sulfoxide extracts of hypocotyls showed a stronger inhibitory effect than that of soybeans on Epstein-Barr virus early antigen activation induced by 12-O-tetradecanoylphorbol-13-acetate. Daidzin,
High intake of phytoestrogens through soybeans and their products is thought to be associated with low incidences of prostate and / or breast cancer in Asian countries. Possible chemopreventive effects of genistin or daidzin on rat prostate carcinogenesis were therefore investigated. Male F344 rats
Soybean consumption is associated with reduced rates of breast, prostate, and colon cancer, which is possibly related to the presence of isoflavones that are weakly estrogenic and anticarcinogenic. We examined the effects of soya consumption on circulating steroid hormones in six healthy females
Osteoclasts are multinuclear giant cells responsible for bone resorption in bone loss diseases, including rheumatoid arthritis, periodontitis, and the aseptic loosening of orthopedic implants. Because of injurious side effects with currently available drugs, it is necessary to continue research
Previous studies have suggested that soy isoflavones exert anticarcinogenic effects against prostate cancer. We propose that soy extracts, containing a mixture of soy isoflavones and other bioactive components, would be a more potent chemo-preventive agent than individual soy isoflavones. We
Due to the association of hormone replacement therapy (HRT) with breast cancer risk, estrogenically active soy isoflavones are considered as an HRT alternative to alleviate menopausal symptoms. However, several recent reports challenged the health benefits of soy isoflavones and associated them with
