Growing evidence suggests that the flavonoid epigallocatechin-3-gallate (EGCG), notably abundant in green tea, has health-promoting properties. We examined the effect of EGCG on cell survival and apoptosis in the prostate cancer cell line PC3. Cell survival was reduced and apoptosis increased significantly with a low dose of 1 µM EGCG. The ability of the anticancer drug cisplatin to promote apo...

Epigallocatechin gallate (EGCG) is a main constituent of green tea polyphenols that are widely used as food preservatives and are considered to be safe for consumption. However, the underlying antimicrobial mechanism of EGCG and the bacterial response to EGCG are not clearly understood. In the present study, a genome-wide transcriptional analysis of a typical spoilage bacterium, Pseudomonas flu...

Inflammatory Breast Cancer (IBC) is a highly aggressive form of cancer characterized by high rates of proliferation, lymphangiogenesis and metastasis, and an overall poor survival. As regular green tea consumption has been associated with improved prognosis of breast cancer patients, including decreased risk of recurrence, here the effects of the green tea polyphenol epigallocatechin-3-gallate ...

In the absence of a fully effective herpes simplex virus (HSV) vaccine, topical microbicides represent an important strategy for preventing HSV transmission. (-)-Epigallocatechin gallate (EGCG) (molecular weight, 458.4) is the primary catechin in green tea. The present study shows that EGCG has greater anti-HSV activity than other green tea catechins and inactivates multiple clinical isolates o...

We previously demonstrated that epigallocatechin-3-gallate (EGCG) synergizes with the immunomodulatory agent glatiramer acetate (GA) in eliciting anti-inflammatory and neuroprotective effects in the relapsing-remitting EAE model. Thus, we hypothesized that mice with chronic EAE may also benefit from this combination therapy. We first assessed how a treatment with a single dose of GA together wi...

Considering the various pharmacological activities of epigallocatechin-3-O-gallate (EGCG) including anticancer, and anti-inflammatory, antidiabetic, and so forth, relatively less attention has been paid to the antiaging effect of EGCG on primary cells. In this study, the preventive effects of EGCG against serial passage-induced senescence were investigated in primary cells including rat vascula...

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...

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...
