Although inhibition of tumor cell growth by genistein is mediated by different types of cell cycle arrest, its regulation of genes related to the cell cycle is not clear. In this study, genistein caused a concentration-dependent growth inhibition in the hormone-independent cell line MDA-MB-435S.
The estrogenic soy isoflavone, genistein, stimulates growth of estrogen-dependent human breast cancer (MCF-7) cells in vivo. Genistin is the glycoside form of genistein and the predominant form found in plants. It is generally believed that genistin is metabolized to the aglycone genistein in the
BACKGROUND
The existence of breast cancer stem-like cells (BCSCs) has profound implications for cancer prevention. Genistein, a predominant isoflavone found in soy products, has multiple robust anti-tumor effects in various cancers, especially in the breast and prostate cancer. In this study, we
Genistein, a natural isoflavonoid found in soybean products, has been proposed to be associated with a lower rate of breast cancer in Asian women. Studies from our laboratory and others have shown that genistein can induce apoptosis by regulating the expression of apoptosis-related genes in breast
As an endocrine disruptor, tyrosine kinase inhibitor, and DNA methyltransferase inhibitor, genistein can interfere with breast cancer development. However, as the results of numerous studies are contradictory, it is unclear whether genistein plays a positive or negative role. Retrospective
BACKGROUND
Tamoxifen users sometimes seek complementary and alternative medicine advice for treatment of a variety of illness and co-administer with phytoestrogen-containing herbs, resulting in an increasing concern of its influence in subsequent endometrial cancer risk. Our study aims to determine
Most breast cancers are estrogen dependent and were sensitive to endocrine therapy, and genistein (GEN) shows strong affinity with human oestrogen receptor beta (ERβ).The present study aimed to investigate the anticancer activity of GEN in breast cancer OBJECTIVE
Genistein, an isoflavonoid, plays roles in the inhibition of protein tyrosine kinase phosphorylation, induction of apoptosis, and cell differentiation in breast cancer. This study aims to induce cellular stress by exposing genistein to determine alterations of miRNA expression profiles in
Genistein is a naturally occurring dietary protein tyrosine kinase (PTK) inhibitor that is hypothesized to be responsible for the lower rate of breast cancer observed in Asian women consuming soy. Although genistein is a potent in vitro PTK inhibitor, its mechanism of action in vivo is not known. In
Genistein, a natural isoflavanoid phytoestrogen, is thought to be the active ingredient in soy that possesses breast cancer preventive properties. The molecular mechanisms that are involved in its cancer preventive properties have not been completely understood. The present study is designed to
Breast cancer is the most common cancer in women. Because genetics is believed to account for only 10-15% of breast cancer cases, the environment, including nutrition, is thought to play a significant role in predisposing women to this cancer. Studies of Asian women suggest that those who consume a
Genistein, a natural isoflavonoid phyto-oestrogen, inhibits the tyrosine kinase activity of growth factor receptors and oncogene products, as well as the in vitro growth of some tumour cell lines. The low incidence of breast cancer in countries with a flavonoid-rich soy-based diet and the protection
Genistein (GEN) is a phytoestrogen found in soybeans. GEN exerts its functions through its interaction with the estrogen receptors (ER), ERα and ERβ, and we previously reported that the ERα/ERβ ratio is an important factor to consider in GEN-treated breast cancer cells. The aim of this study was to
The role of beta-glucuronidase in genistein biotransformation was investigated in a human breast cancer MDA-MB-231 xenogeneic athymic mouse model. Genistein combined polysaccharide (GCP), a genistein aglycone rich functional food supplement was used in these experiments. Tumor-bearing mice were
We have hypothesized that early exposure to soy confers lifetime protection against breast cancer. This was investigated in Sprague Dawley CD rats exposed neonatally and prepubertally to injections of pharmacological doses of genistein and perinatally to physiological doses of genistein in the diet.
