Decreased expression of the cell-cell adhesion molecule, E-cadherin, promotes dedifferentiation and invasiveness of human carcinoma cells, whereas this process can be reversed by reexpression of E-cadherin (U. H. Frixen et al., J. Cell Biol., 113: 173-185, 1991; J. H. Schipper et al., Cancer Res., 51: 6328-6337, 1991). In this work we studied the involvement of extracellular matrix-degrading pr...

BACKGROUND Isodeoxyelephantopin (IDOE) isolated from Elephantopus scaber L. (Didancao) is used in Chinese medicine for the treatment of some types of cancer. The anti-cancer mechanism of IDOE remains unclear. This study aims to investigate the antiproliferative activity of IDOE on breast carcinoma T47D cells and lung carcinoma A549 cells. METHODS The growth inhibitory effects of IDOE on breas...

OBJECTIVES Our aim was to examine how certain signal transduction pathways influence the regulation of hormone-dependent kallikrein (KLK) gene expression in androgen-sensitive breast cancer cell lines. METHODS We used the breast cancer cell lines T47D and BT474, treated with steroid hormones or various pathway inhibitors. KLKs were quantified by ELISA. RT-PCR, Western blots and immunoprecipit...

Metformin, one of the most widely prescribed antihyperglycemic drugs, has recently received increasing attention for its potential effects with regard to cancer prevention and treatment. However, the mechanisms behind the suppression of cancer cell growth by metformin remain far from completely understood. The aim of the present study was to investigate whether metformin could regulate histone ...

During breast carcinoma progression, the three-dimensional (3D) microenvironment is continuously remodeled, and changes in the composition of the extracellular matrix (ECM) occur. High throughput screening platforms have been used to decipher the complexity of the microenvironment and to identify ECM components responsible for cancer progression. However, traditional screening platforms are typ...

Scoparia dulcis Linn plays an important role in treatment because it contains active compounds that are proven to have a variety of activities, including cytotoxicity on various cancer cells. The objective this study is isolate and identify the cytotoxic ethyl acetate fraction dulcis, observe cell cycle inhibition induction apoptosis vitro, carry out molecular studies using silico studies. A ne...

Zearalenone (Zen) is a mycotoxin with estrogenic effect which contaminates cereals. In cell culture, Zen and its metabolite, alpha-Zearalenol (alpha-Zel), stimulate breast cancer cells growth. Today hormone-dependent cancers are important because of high incidence and death rate. Previous studies showed that Zen and alpha-Zel have an effect on hormone-dependent cancers. This study explains the ...
