EGCG fish oil

Jin Feng, He Cai, Hua Wang, Chunyang Li, Songbai Liu
Conjugates of ovalbumin (OVA) with (+)-catechin (C), (-)-epigallocatechin (EGC) or (-)-epigallocatechin gallate (EGCG) were synthesized through a free-radical grafting approach. The covalent binding between OVA and catechins was confirmed by sodium dodecyl sulfate-polyacrylamide gel electrophoresis (SDS-PAGE) and matrix-assisted laser desorption/ionization time-of-flight mass spectrometry (MALDI-TOF-MS). OVA-catechin conjugates were further characterized by a combination of steady-state fluorescence spectroscopy, differential scanning calorimetry (DSC), Fourier transform infrared (FTIR) spectroscopy and circular dichroism (CD) analyses...

Animal and human studies suggest fish oil and green tea may have protective effect on prostate cancer. Fatty acid synthase (FAS) has been hypothesized to be linked to chemoprotective effects of both compounds. This study evaluated the independent and joint effects of fish oil (FO) and green tea supplement (epigallocatechin-3-gallate, EGCG) on FAS and Ki-67 levels in prostate tissue. Through a double-blinded, randomized controlled trial with 2 × 2 factorial design, 89 men scheduled for repeat prostate biopsy following an initial negative prostate biopsy were randomized into either FO alone (1...

Flavonoids and fish oils have anti-inflammatory and immune-modulating influences. The purpose of this study was to determine if a mixed flavonoid-fish oil supplement (Q-Mix; 1000 mg quercetin, 400 mg isoquercetin, 120 mg epigallocatechin (EGCG) from green tea extract, 400 mg n3-PUFAs (omega-3 polyunsaturated fatty acid) (220 mg eicosapentaenoic acid (EPA) and 180 mg docosahexaenoic acid (DHA)) from fish oil, 1000 mg vitamin C, 40 mg niacinamide, and 800 µg folic acid) would reduce complications associated with obesity; that is, reduce inflammatory and oxidative stress markers and alter genomic profiles in overweight women...

The large majority of clinical prostate cancers remain dependent on androgen receptor (AR) activity for proliferation even as they lose their responsiveness to androgen deprivation or antagonism. AR activity can be maintained in these circumstances by increased AR synthesis--often reflecting increased NF-κB activation; upregulation of signaling pathways that promote AR activity in the absence of androgens; and by emergence of AR mutations or splice variants lacking the ligand-binding domain, which render the AR constitutively active...

UNLABELLED: Trout-skin (Oncorhynchus mykiss) gelatin-based films containing antioxidants (epigallocatechin gallate (EGCG), 50 and 250 ppm w/w) and green tea powder (1% and 20% w/w of gelatin) were tested for tensile strength, elastic modulus, and elongation, and oxygen and water vapor transmission rates, in vitro antioxidant activity using the DPPH (2,2-diphenyl-1-picrylhydrazyl) assay and effect on stabilizing cod-liver oil held under mild thermal abuse conditions. Cod-liver oil overlaid with films was stored at 40 °C for 20 d and analyzed for peroxide value (PV) and thiobarbituric acid reactive substances (TBARS)...

Extracellular plaques of beta-amyloid (Abeta) peptides are implicated in Alzheimer's Disease (AD) pathogenesis. Abeta formation is precluded by alpha-secretase, which cleaves within the Abeta domain of APP generating soluble APP-alpha (sAPP-alpha). Thus, alpha-secretase upregulation may be a target AD therapy. We previously showed green tea derived EGCG increased sAPP-alpha in AD mouse models. However, the comparable effective dose of EGCG in humans may exceed clinical convenience and/or safety. Epidemiological studies suggested fish oil consumption is associated with reduced dementia risk...

In this study, we investigated the extent of the cytotoxicity effect of oxidised lipids and whether tea catechins namely (-)epigallocatechin-3 gallate (EGCG) decreased lipid peroxidation in caco-2 cells. Cells treated with 0-100 microg/ml fish oil or methyl linoleate (ML) oxidised by UV irradiation for 24 h, 48 h and 72 h, indicated a substantial decrease in cell viability especially in samples treated with 100 microg/ml oxidised lipid. Addition of malondialdehyde (MDA) and hydroxynonenal (50 microM) also reduced cell viability...

The effect of a combination of (-)-epigallocatechin-3-gallate (EGCG) with fish oil on intestinal tumorigenesis in Apc (Min/+) mice fed a high-fat diet was investigated in the present study. The combined treatment of EGCG and fish oil for 9 weeks reduced the tumor number by 53% as compared to controls while neither agent alone had a significant effect. Apoptosis was significantly increased in all treatment groups. beta-Catenin nuclear positivity in adenomas from the combination group was lower than control mice, implicating the modulation of Wnt signaling by the combination...

UNLABELLED: Heterocyclic amines (HCAs) are potent mutagens and carcinogens formed during cooking of meats or fish. They are, therefore, widely consumed by humans. PURPOSE: A series of studies explore modulation of the mutagenicity and carcinogenicity of typical HCAs like 2-amino-3-methylimidazo[4,5-f]quinoline (IQ), and of 2-amino-1-methyl-6-phenylimidazo-[4,5-b]pyridine (PhIP), through dietary fat, green or black tea, and tea polyphenols like epigallocatechin gallate (EGCG) and theaflavin gallate (TFG)...
