The effects of epigallocatechingallate (EGCG) on the migration and expression of MMP-2 of uveal melanoma cells have not been reported. We studied this effect and relevant signaling pathways in a human uveal melanoma cell line (M17). MTT study found that EGCG did not affect the cell viability of M17 cells up to 100 µM. Wound-healing assay showed that EGCG significantly reduced the migration of m...

The green tea polyphenol epigallocatechin-3-gallate (EGCG) is widely consumed as a dietary supplement. Its potential properties include slowing aging and extending lifespan, although how exactly this is achieved remains unclear. Here, we report that EGCG promoted healthy lifespan in Caenorhabditis elegans when administered throughout or only at early-to-mid adulthood. Specifically, EGCG extende...

Green tea, particularly epigallocatechin-3-gallate (EGCG), may affect body weight and composition, possibly by enhancing fat oxidation. The aim of this double-blind, randomized placebo-controlled cross-over study was to investigate whether 3-day supplementation with EGCG (282 mg/day) stimulates fat oxidation and lipolysis in 24 overweight subjects (age = 30 ± 2 yrs, BMI = 27.7 ± 0.3 kg/m(2)). E...

Epigallocatechin gallate (EGCG), the most abundant flavanoid in green tea, is currently being evaluated in the clinic due to its benefits in the treatment of amyloid disorders. Its anti-amyloidogenic effect has been attributed to direct interaction of the intact molecule with misfolded polypeptides. In addition, antioxidant activity is also involved in the anti-amyloidogenic role. The detailed ...

Toll-like receptors (TLRs) play an important role in recognition of microbial components and induction of innate immunity. The microbial components trigger the activation of two downstream signaling pathways of TLRs; MyD88- and/or TRIF-dependent pathways leading to activation of NF-kappaB. (-)-Epigallocatechin-3-gallate (EGCG), a flavonoid found in green tea, is known to inhibit NF-kappaB activ...

EGCG (Epigallocatechin-3-gallate) is the major active principle catechin found in green tea. Skepticism regarding the safety of consuming EGCG is gaining attention, despite the fact that it is widely being touted for its potential health benefits, including anti-cancer properties. The lack of scientific data on safe dose levels of pure EGCG is of concern, while EGCG has been commonly studied as...

Many diseases, including diabetes mellitus and Alzheimer’s disease, are related to accumulation of aggregated (poly)peptides in tissues. These aggregates called amyloids are insoluble and up till now no adequate treatment of amyloid-related diseases is available. One of the most promising therapeutic agents is the polyphenol epigallocatechin-3-gallate (EGCG). It has been shown that EGCG inhibit...

BACKGROUND This experiment was performed to determine the effect of polyphenolic (-)-epigallocatechin (EGCG), the most abundant catechin of green tea, given at reperfusion period. METHODS Isolated rat hearts were subjected to 30 min of regional ischemia and 2 h of reperfusion. Green tea extract (GT) was perfused with the following concentrations; 0, 0.5, and 1 microM (GT-O, GT-0.5, and GT-1, ...

OBJECTIVES The epigallocatechin-3-gallate (EGCg) that is present in human diet originates mainly from tea leaves. Catechins have a number of possible application as medicines, however, there is no consistent evidence showing their influence on the gastrointestinal tract. Thus, the aim of the present study was to investigate the effect of EGCg on the motility of the murine isolated intestine. ...

Background: Paclitaxel well known as anti-cancer drug has been shown to cause alopecia in chemotherapy. The paclitaxel chemotherapy-mediated alopecia is induced by apoptotic damage in human dermal papilla (HDP) cells. Epigallocatechin-3-gallate (EGCG) inhibits apoptosis against anti-cancer drug such as cisplatin. EGCG, one of the green tea extract ingredients, has been reported to enhance cell ...
