Formononetin is one of the main components of red clover plants, and is considered as a typical phytoestrogen. This study further investigated that formononetin inactivated IGF1/IGF1R-PI3K/Akt pathways and decreased cyclin D1 mRNA and protein expression in human breast cancer cells in vitro and in
BACKGROUND
Calycosin and formononetin are two main components of isoflavones. In our previous studies, we have respectively reported their antitumor activities on breast cancer cell MCF-7. To further investigate the feasibility of isoflavones in clinically treating breast carcinoma, here we
For postmenopausal cardiovascular disease, long-term estrogen therapy may increase the risk of breast cancer. To reduce this risk, estrogen may be replaced with the phytoestrogen formononetin, but how formononetin acts on vascular endothelial cells (ECs) and breast cancer cells is unclear. Here, we
Background
Formononetin, an active ingredient isolated from the traditional Chinese medicinal herb
Astragalus membranaceus, has anticancer and chemoresistance-reducing biological activities. We evaluated the efficacy of
formononetin in improving the tumoricidal effect of
Many breast cancer patients suffer from obvious side effects induced by chemotherapy. Formononetin (FM), one kind ingredient of Chinese herbal medicine, has been suggested to inhibit MCF-7 breast cancer cells. And recently metformin (MET) has gained more attention as a potential anti-cancer drug.
Formononetin is a naturally existing isoflavone, which can be found in the roots of Astragalus membranaceus, Trifolium pratense, Glycyrrhiza glabra, and Pueraria lobata. It was found to be associated with inhibition of cell proliferation and cell cycle progression, as well as induction of apoptosis
Formononetin is one of the main active components of red clover plants, and considered as a phytoestrogen. Its pharmacological effects in vivo may be either estrogenic or anti-estrogenic, mainly depending upon the estrogen levels. Our recent studies suggested that formononetin inactivated
Phytoestrogens can exhibit agonistic actions on estrogen-dependent gene expression in breast cancer cells. Since several different phytoestrogens may be found within a single dietary plant source, we sought to investigate whether estrogen-dependent gene expression may be further influenced by the
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
Formononetin is an isoflavonoid phytoestrogen found in animal fodder and in certain human foodstuffs. Since high consumption of formononetin has been implicated in infertility among ruminants and may relate to human breast cancer, we developed a radioimmunoassay method and applied it to quantitate
Dietary phytoestrogens have been implicated in infertility among ruminants and may relate to human breast cancer risk. Formononetin is an isoflavonoid phytoestrogen found in animal fodder and in certain human foodstuffs. To investigate a possible mechanism by which phytoestrogens might influence
BACKGROUND
Astragali radix (Huang Qi, HQ), a well-known Chinese herbal medicine, is widely coadministered with many other drugs for treating diseases. The potential herb-drug interactions (HDIs) possibly occur during the combination therapy. P-glycoprotein (P-gp) and breast cancer resistance protein
OBJECTIVE
To study the estrogenic activity of formononetin in vitro.
METHODS
We have established a highly sensitive bioassay system by placing estrogen-responsive elements upstream of the luciferase reporter gene, and used this assay to determine the estrogenic activity of formononetin. Cell growth
BACKGROUND
Biochanin A and formononetin are O-methylated isoflavones that are isolated from the root of Astragalus membranaceus, and have antitumorigenic effects. Our previous studies found that formononetin triggered growth-inhibitory and apoptotic activities in MCF-7 breast cancer cells. We
