Isoflavones have multiple actions on cell functions. The most prominent one is the activation of estrogen receptors. Other functions are often overlooked, but are equally important and explain the beneficial health effects of isoflavones. Isoflavones are potent dual PPARα/γ agonists and exert anti-inflammatory activity, which may contribute to the prevention of metabolic syndrome, atheroscleros...

Isoflavones are a subgroup of phytoestrogens, natural plant substances with structure similar to 17-beta-estradiol and capable of binding to estrogen receptors (ERs). Isoflavones possess higher affinity to ERbeta than to ERalpha and may have a potency to activate both genomic and non-genomic estrogen signaling pathways. In addition, isoflavones interact with the metabolism of steroid hormones. ...

Soy intake has been associated with a lower risk of prostate cancer. Soybeans contain isoflavones, genistein, daidzein and glycitein, which have shown anti-cancer effects in cell culture animal studies. Recently clinical trials soy isoflavones humans also promising results. anti-oxidant anti-inflammatory properties may be important for their anticancer effects. In addition, recent studies signi...

Botanicals, being safe because of their natural origin, are associated with potential health benefits due to isoflavones-rich content. Isoflavones as plant-generated secondary metabolites formed defend against environmental stress such UV radiation, mechanical damage, or any other attack from the surroundings. Kudzu (Pueraria roots and flowers), red clover (Trifolium pratense), soy (Glycine max...

BACKGROUND AND AIMS The substantial characteristics of Irritable Bowel Syndrome (IBS) are associated with estrogens in women. Both soy isoflavones and vitamin D can modulate estrogen receptors in the colonic smooth muscles. The aim of this study was to investigate the effects of soy isoflavones, vitamin D and their probable interactions in women with IBS. METHODS In a factorial blinded random...

We previously showed that genistein, the major bioactive component of soy isoflavones, acts as a radiosensitizer and potentiates prostate tumor cell killing by radiation in vitro and in animal tumor models in vivo. However, when given alone in vivo, pure genistein promoted increased lymph node metastasis, which was not observed with a soy isoflavone mixture consisting of genistein, daidzein, an...

Isoflavones have been suggested to have protective effects on certain cancers. However, the association of soya foods or dietary isoflavones with the risk of myelodysplastic syndromes (MDS) has not been examined. Thus, the aim of this hospital-based case-control study undertaken in China in 2012-2013 was to investigate the association between dietary isoflavone intake and MDS risk. The analysis...

Isoflavones contained in the root and flower of Kudzu (Pueraria lobata and related species) are suggested to be the critical component for its effects. Although metabolism of soy isoflavones has been well studied, the composition of isoflavones found in Kudzu is completely different from that of soy isoflavones. In the present study, we investigated whether isoflavones found in the flower of Pu...

Isoflavones are reported to have an estrogenic activity to prevent prostate cancer. Therefore, it is necessary to analyze the factors influencing the absorption and metabolism of isoflavones using detailed and precise dietary information. We evaluated the relationship between the amount of intake of soybean isoflavones in the diet and its serum levels in 88 hospitalized patients (22 with prosta...
