Vascular problems are the most common complications in diabetes. Substantial evidence from epidemiological and pathophysiological studies show that hyperglycemia is a major risk factor for macrovascular complications in patients with diabetes. (-)-Epigallocatechin-3-gallate (EGCG), the major catechin derived from green tea, is known to exert a variety of cardiovascular beneficial effects. The p...

Plant extracts and compounds are applied to a wide variety of diseases in which traditional drugs have proven ineffective. A quickly developing trend in biomedicine is the therapeutic use of siRNA (short interfering RNA) structures. The focus of this study was on evaluating the gene expression involved in the modulation of apoptosis, in cases of combinatorial treatment (-)-epigallocatechin-3-ga...

The study on incorporation of [3H](-)-epigallocatechin gallate (EGCG) into human lung cancer cell line PC-9 indicated that the [3H]EGCG incorporation was significantly enhanced by (-)-epicatechin, an inert tea polyphenol without a galloyl moiety. (-)-Epicatechin enhanced apoptosis, growth inhibition of PC-9 cells, and inhibition of tumor necrosis factor-alpha release from BALB/c-3T3 cells by EG...

Recent years have witnessed a significant interest in phytonutrients as treatment module for range of diseases, including cancers. Catechins, predominant green tea are potent antioxidants belonging to the flavonoid family that been linked epidemiologically lower prevalence prostate pathologies Asian nations. In present work, we investigated ameliorative potential catechins (epigallocatechin, EG...

Background and Aim: Traumatic brain injury is one of the leading causes of mortality and disability in young adults. Epigallocatechin-3-gallate, the antioxidant compound of green tea, has been proposed to have antioxidant and anti-inflammatory properties. This study evaluates the potential effects of epigallocatechin-3-gallate on the early clinical outcome and serum S100B levels (biomarker for ...

The balance between embolic risk and bleeding represents a clinical challenge in cancer patient treatment, encouraging studies on adjuvant oncologic treatments. Thereby, this study evaluated the vitro effect of green tea extract (GTE) epigallocatechin-3-gallate (EGCG) hemostasis modulation antineoplastic melanoma cells (B16-F10) by applying platelet aggregation, angiogenesis viability cell assa...

Background: Epigallocatechin gallate (EGCG), a major constituent of green tea, has been introduced as a potent free radical scavenger and can effectively reduce free radical-induced lipid peroxidation. Since free radical injury plays an important role in neuronal damage in Parkinson’s disease (PD), this study examined whether EGCG administration would reduce functional asymmetry in an experimen...

Reactive oxygen species trigger cardiomyocyte cell death via increased oxidative stress and have been implicated in the pathogenesis of cardiovascular diseases. The prevention of cardiomyocyte apoptosis is a putative therapeutic target in cardioprotection. Polyphenol intake has been associated with reduced incidences of cardiovascular disease and better overall health. Polyphenols like epigallo...

Among black tea polyphenols, theaflavins were generally considered to be the most effective in cancer chemoprevention. In this study, we examined the inhibitory effects of black tea polyphenols, including theaflavin (TF-1), a mixture (TF-2) of theaflavin-3-gallate and theaflavin-3'-gallate, theaflavin-3,3'-digallate (TF-3), and the green tea polyphenol (-)-epigallocatechin-3-gallate (EGCG) on 1...

Progressive cognitive decline is one of the hallmark symptoms of Alzheimer’s disease (AD) which can be modeled by β-amyloid injection into specific regions of brain. Since epigallocatechin-3-gallate (EGCG) is a potent antioxidant agent which its role against oxidative stress and inflammation has been shown in prior studies, we tried to determine whether EGCG administration protects against β-am...
