一般說明

(−)-表没食子儿茶素没食子酸酯（来源于绿茶）是绿茶中的主要生物活性成分，占儿茶素总含量的50-80%。它的化学结构类似于表儿茶素没食子酸酯(ECG)——没食子酸和表没食子儿茶素形成的酯类物质。

應用

(-)-表没食子儿茶素没食子酸酯已被用于：
  • 作为小鼠TRAMP转移性前列腺细胞系的抗肿瘤剂，用于细胞增殖试验、凋亡检测和改良型Boyden-chamber试验
  • 通过死亡相关蛋白激酶-2途径诱导急性髓细胞白血病细胞死亡，用于细胞活力、细胞周期和凋亡分析
  • 作为小鼠前破骨细胞系RAW264.7的破骨细胞分化的抑制剂
  • 促进成肌细胞分化

生化／生理作用

(-)-表没食子儿茶素没食子酸酯 (EGCG)是一种抗氧化多酚类黄酮化合物，它通过抑制端粒酶和DNA甲基转移酶活性而发挥抗肿瘤作用。EGCG可抑制基质金属蛋白酶-2（MMP-2）、MMP-9的表达并降低肿瘤的侵袭能力。EGCG可阻断表皮生长因子（EGF）受体和人表皮生长因子受体-2（HER-2）的活化。EGCG可增加骨矿物质密度并减少骨吸收。EGCG通过抑制核因子κ-B受体活化因子配体（RANKL）诱导的核因子 κ B(NF-κB)转录活性，进而抑制破骨细胞生成。EGCG可减少骨骼肌萎缩。EGCG具有抗衰老性，可增加成肌细胞分化。EGCG可抑制脂肪酸合成酶和谷氨酸脱氢酶活性。

Glutamine Metabolism is Dysregulated in Many Cancer Cells

This is 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.

Dietary Antioxidants

Antioxidants protect biological systems from oxidative damage produced by oxygen-containing free radicals and from redoxactive transition metal ions such as iron, copper, and cadmium.
