Regulation of Tumor Necrosis Factor-alpha Signaling in Rheumatoid Arthritis Synovial Fibroblasts by Green Tea Polyphenol Epigallocatechin-3-gallate
… joint damage and destruction. 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 …

Green Tea Polyphenol Epigallocatechin-3-gallate Inhibits Hepatocyte Growth Factor-Induced Tumor Cell Migration and Invasion In Vitro and In Vivo
… 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 활성화를 억제하였다. 더 나아가 시험관내 실험에서 …

Biochemistry and genetics of the pathway for the anaerobic degradation of aromatic compounds by Eubacterium oxidoreducens
… pathway for the anaerobic degradation of gallate, pyrogallol and phloroglucinol by Eubacterium oxidoreducens was investigated. Phloroglucinol reductase was purified 90-fold, from the soluble fraction of cell extract, to electrophoretic homogeneity. The enzyme was an α₂ homodimer with a …

Metabolism of Gallic Acid by Eubacterium Oxidoreducens
Gallate was decarboxylated by cell extracts of Eubacterium oxidoreducens with pyrogallol as the only detectable product. A phloro-glucinol reductase catalyzed the conversion of phloroglucinol to dihydrophloroglucinol, using NADPH as the source of electrons. Extracts of cells grown on gallate and …
