Cell growth inhibition and gene expression regulation by (-)-epigallocatechin-3-gallate in human cervical cancer cells.

24 Sep 2009 EGCG [(-)-epigallocatechin-3-gallate] has shown its antitumor ability and perhaps a potential regimen for cancer patients. The goal of this study was to investigate the effect of EGCG on human papilloma virus (HPV) positive cervical cancer cell ... Read more...

Apoptosis induction effects of EGCG in laryngeal squamous cell carcinoma cells through telomerase repression.

24 Sep 2009 Epigallocatechin-3-gallate (EGCG), the major component of green tea polyphenol, has potent efficiency to prevent the growth of a variety of cancer cells. As a novel anticancer agent for treatment of cancers, EGCG is promising and the mechanism has ... Read more...

Dietary polyphenols generate nitric oxide from nitrite in the stomach and induce smooth muscle relaxation.

20 Sep 2009 Nitrite, considered a biological waste and toxic product, is being regarded as an important physiological molecule in nitric oxide (NO) biochemistry. Because the interaction of dietary phenolic compounds and nitrite would be kinetically (due to the ... Read more...
