Potential for selection of new peanut genotypes with enhanced polyphenol antioxidant content
… breeding of new peanut genotypes with enhanced polyphenol content and antioxidant capacity. The specific objectives of this project were: 1) to estimate the genotype (G), environment (E) and G x E influence on the expression of polyphenols in a Recombinant Inbred Line (RIL) peanut population; 2) …

Effect of a polyphenol-rich diet on vascular function and other markers of cardiovascular risk
… and intervention evidence to date indicates that polyphenol- rich foods, in particular berries and dark chocolate, may have the potential to influence cardiovascular disease risk. However, there are very few polyphenol-specific dietary intervention studies, and none of sufficiently robust design …

The effects of polyphenol rich chocolate on cardiovascular risk and glycaemic control in type 2 diabetes mellitus
Background:Type 2 diabetes mellitus (T2DM) is characterised by increased rates of morbidity and mortality, much of which is related to cardiovascular disease. T2DM is considered to be a non-communicable disease, with its cause and aetiology linked to a number of genetic factors, which are …

Characterising the techno- and bio-functional properties of milk protein-polyphenol complexes for application in performance nutrition
… hybrid beverages, rich in milk proteins and polyphenols, have considerable potential in this area, because both proteins and polyphenols have been positively linked to muscle strength and recovery. However, there is limited knowledge of the effects of protein-polyphenol interactions on the …

The effect of polyphenol-rich flaxseed muffins on glycaemic, insulinaemic and 24-hour glucose response in healthy adults
… and bioactive compounds, such as antioxidants, polyphenols and dietary fibre. These compounds help to prevent diseases, such as cardiovascular disease (CVD) and Type 2 Diabetes (T2D), and they enhance metabolic health. It is important to investigate the use of flaxseed as a functional ingredient …

Regulation of Tumor Necrosis Factor-alpha Signaling in Rheumatoid Arthritis Synovial Fibroblasts by Green Tea Polyphenol Epigallocatechin-3-gallate
… Epigallocatechin-3-gallate (EGCG) is a polyphenol found in green tea that has been shown to have an anti-inflammatory effect in RA. Previous studies suggest that EGCG blocks IL-1β signaling pathways to inhibit angiogenesis and tissue destruction in RA. However, little research has been …

Green Tea Polyphenol Epigallocatechin-3-gallate Inhibits Hepatocyte Growth Factor-Induced Tumor Cell Migration and Invasion In Vitro and In Vivo
… 효과적으로 억제하는 물질을 찾아보고자하였고 녹차의 성분 중 생체에 영향을 주는 중요한 polyphenol인 Epigallocathechin-3-gallate(EGCG)가 HGF/Met 신호체계를 효과적으로 억제할 수 있다는 것을 발견하였다. EGCG는 HGF에 의한 Met의 활성 방식이 autocrine이든 paracine이든 공히 억제할 수 있었다. 또한 돌연변이 Met(M1268T 돌연변이)의 활성화도 역시 EGCG에 의해서 부분적으로 억제되었다. EGCG는 HGF에 의해 유발된 세포의 이동과 MDCK2 세포들에서의 uPA …
