Descripción general

(−)-Epigallocatechin gallate from green tea is the prime bioactive component, accounting for 50-80% of the total catechin content. It comprises a chemical structure similar to that of epicatechin gallate (ECG), an ester of gallic acid and epigallocatechin.

Aplicación

(-)-Epigallocatechin gallate has been used:
  • as an anti-tumor agent on murine TRAMP metastatic prostate cell line by cell proliferation assay, apoptosis detection and modified Boyden-chamber assay
  • induces cell death in acute myeloid leukaemia through death associated protein kinase-2 pathway analyzed through cell viability, cell cycle and apoptosis assay
  • as an inhibitor of osteoclast differentiation in murine preosteoclast cell line RAW264.7
  • to promote myogenic differentiation

Acciones bioquímicas o fisiológicas

(-)-Epigallocatechin gallate (EGCG), an antioxidant polyphenol flavonoid exerts anti-tumor properties by inhibiting telomerase and DNA methyltransferase activity. EGCG inhibits the expression of matrix metalloproteinase-2 (MMP-2), MMP-9 and reduces the invasiveness. EGCG blocks the activation of epidermal growth factor (EGF) receptors and human epidermal growth factor receptor-2 (HER-2). EGCG increases bone mineral density and reduces bone resorption. EGCG inhibits osteoclastogenesis by inhibiting receptor activator of nuclear factor κ-B ligand (RANKL) induced nuclear factor κ B (NF-κB) transcriptional activity. EGCG reduces skeletal muscle atrophy. EGCG has anti-aging property and increases myogenic differentiation. EGCG inhibits fatty acid synthase and glutamate dehydrogenase activity.

Glutamine Metabolism is Dysregulated in Many Cancer Cells

Sigma-Aldrich presents an article about how proliferatively active cells require both a source of carbon and of nitrogen for the synthesis of macromolecules. Although a large proportion of tumor cells utilize aerobic glycolysis and shunt metabolites away from mitochondrial oxidative phosphorylation, many tumor cells exhibit increased mitochondrial activity.

Fatty Acid Synthesis and Metabolism in Cancer Cells

Information on fatty acid synthesis and metabolism in cancer cells. Learn how proliferatively active cells require fatty acids for functions such as membrane generation, protein modification, and bioenergetic requirements. These fatty acids are derived either from dietary sources or are synthesized by the cell.
