Epigallocatechin-3-gallate (EGCG) is a major constituent of green tea, but its effects on glioma cell growth have not been reported. The aim of this study was to investigate the anticancer effect of EGCG on the growth and invasive ability of glioma cells, as well as the molecular mechanisms responsible for it. Two glioma cell lines were treated with EGCG, and its effect on cell proliferation an...

Inducible nitric oxide synthase (iNOS) is a main enzyme producing nitric oxide during inflammation and thus contributes to the initiation and development of inflammatory cardiovascular diseases such as atherosclerosis. Epigallocatechin-3-gallate (EGCG), the major catechin derived from green tea, has multiple beneficial effects for treating cardiovascular disease, but the effect of EGCG on the e...

Epigallocatechin gallate (EGCG) is the major polyphenol in green tea and the main bioactive compound responsible for the health benefits of tea consumption. The molecule exhibits antimicrobial and anti-inflammatory activities. However, little is known about the molecular mechanisms by which EGCG elicits those activities. In this study, we examined the effects of EGCG on lipopolysaccharide (LPS)...

The major component in green tea polyphenols, epigallocatechin-3-gallate (EGCG), has been demonstrated to prevent carcinogenesis. To improve the effectiveness of EGCG, liposomes were used as a carrier in this study. Reverse-phase evaporation method besides response surface methodology is a simple, rapid, and beneficial approach for liposome preparation and optimization. The optimal preparation ...

The effects of (-)-epigallocatechin gallate (EGCG) on the contraction of floating collagen gel by fibroblasts were investigated. EGCG inhibited collagen gel contraction dose-dependently. On the basis of the fact that platelet-derived growth factor (PDGF) is one of the serum components with stimulatory activity in collagen gel contraction, we examined the possibility that interaction between EGC...

The addition of an aqueous solution diketopiperazine cyclo(Pro-Xxx) (Xxx: amino acid residue) to (?)-epigallocatechin-3-O-gallate (EGCg) led precipitation the complex EGCg and cyclo(Pro-Xxx). molecular capture abilities using were evaluated by ratio amount included in precipitates with that total used. Stronger hydrophobicity side chain residue a higher ability. Furthermore, ability decreased w...

In this study, complexes formed by sodium caseinate (CS) and different concentrations of (−)-epigallocatechin-3-gallate (EGCG) were successfully prepared. The structures the CS–EGCG then analyzed fluorescence spectroscopy, circular dichroism, Fourier transform infrared spectroscopy (FTIR). Their thermodynamic features also Van't Hoff equation before evaluating antioxidant properties as well emu...

Melanoma is the most serious type of skin disease and a leading cause of death from skin disease due to its highly metastatic ability. To develop more effective chemopreventive agents for the prevention of melanoma, we have determined the effect of green tea catechins on the invasive potential of human melanoma cells and the molecular mechanisms underlying these effects using A375 (BRAF-mutated...

STATEMENT OF THE PROBLEM Self-etch adhesives can activate matrix metalloproteinase (MMP) which hydrolyzes organic matrix of demineralized dentin. Epigallocatechin gallate (EGCG), especially found in green tea, could inhibit the activation of MMP. PURPOSE The aim of this study was to evaluate the effect of adding Epigallocatechin gallate (EGCG) into two types of adhesives on dentin bond streng...

Due to the anti-diabetic and antioxidant activity of green tea epigallocatechin-gallate (EGCG), this research study was conducted to evaluate, for the first time, the efficacy of chronic treatment of EGCG on alleviation of hyperalgesia in streptozotocin-diabetic (STZ-diabetic) rats. Male Wistar rats were divided into control, diabetic, EGCG-treated-control and diabetic and sodium salicylate (SS...
