Genistein inhibits human papillary thyroid cancer cell detachment, invasion and metastasis
In conclusion, for the first time, our study suggested that genistein has anticarcinoma effect for PTC patients in the range of 2.5 and 80 μg/ml in thyroid carcinoma cells, which was probably through cytoplasmic translocation of β-catenin. Further study will be needed to determine whether genistein could be used in clinical trial of high-risk PTC.

7-Difluoromethoxyl-5,4'-di-n-octyl genistein inhibits the stem-like characteristics of gastric cancer stem-like cells and reverses the phenotype of epithelial-mesenchymal transition in gastric cancer cells.
The objective of the present study was to investigate whether DFOG inhibits the stemness and reverses the epithelial-mesenchymal transition (EMT) phenotype of gastric cancer stem-like cells (GCSLCs) derived from human gastric cancer SGC-7901 cells and to identify its potential mechanism. Sphere-forming cells (SFCs) from the SGC-7901 cells possessed the properties of GCSLCs. DFOG preferentially inhibited self-renewal, cell migration and cell invasion, and downregulated the expression of stem cell biomarkers in a dose-dependent manner. At the molecular level, these effects were accompanied by the downregulation of forkhead b...

Genistein Induces G2/M Arrest in Gastric Cancer Cells by Increasing the Tumor Suppressor PTEN Expression.
Abstract Genistein, a major isoflavone found in soybeans, exhibits anticarcinogenic properties. The inhibitory effect of genistein on cell proliferation is associated with G2/M cell cycle arrest and inhibition of cdc2 activities. Here we assessed the role of PTEN in regulation of genistein-mediated G2/M cell cycle arrest in the gastric cancer cell lines (SGC-7901 and BGC-823). After 24 h following treatment, genistein induced a concentration-dependent accumulation of cells in the G2/M phase of the cell cycle. The sustained G2/M arrest by genistein in SGC-7901 and BGC-823 cells is associated with increased phospho...
