Hormones and their receptors play an important role in the development and progression of breast cancer. Hormones regulate the proliferation of breast cancer cells through binding between estrogen or progestins and steroid receptors that may reside in the cytoplasm or be transcriptionally activated

Estrogen plays a crucial role in the development of breast cancer, and the inhibition of estrogen synthesis has been an important target for the prevention and treatment of this disease. The rate-limiting reaction of the hormone biosynthesis is catalyzed by cytochrome P450 (CYP) 19 enzyme or

Involvement of a post-transcriptional mechanism in the inhibition of CYP1A1 expression by resveratrol in breast cancer cells.

Resveratrol decreases basal and induced CYP1A1 mRNA/protein levels in both in vitro and in vivo models, and some studies suggest that resveratrol acts as an aryl hydrocarbon receptor (AhR) antagonist. Treatment of T47D or MCF-7 cells with 10 microM resveratrol inhibited induction of CYP1A1 mRNA and

Estrogen and resveratrol regulate Rac and Cdc42 signaling to the actin cytoskeleton of metastatic breast cancer cells.

OBJECTIVE Drug resistance remains a major challenge for effective breast cancer chemotherapy. Resveratrol (Res) is a promising candidate for overcoming cancer chemoresistance, but it has low bioavailability due to poor absorption, and ready metabolism limits its application. This study aims to

The antiproliferative activity of resveratrol results in apoptosis in MCF-7 but not in MDA-MB-231 human breast cancer cells: cell-specific alteration of the cell cycle.

Resveratrol, a natural phytoalexin, has gained much interest on the basis of its potential chemopreventive activity against human cancer. In this work, using the human breast cancer cell lines MCF-7 and MDA-MB-231, we have analyzed a possible mechanism by which resveratrol could interfere with cell
