人参皂甙 Rh2,从人参属人参提取的 triterpene saponin,对多重癌症的展览药理学活动。然而,人参皂甙 Rh2 的 anticancer 机制是不清楚的。在这研究,我们发现人参皂甙 Rh2 有效地禁止生长并且导致 HL-60 房间的 apoptosis。用 microarray 技术,我们发现了那个肿瘤坏死因素 --(TNF-) 清楚地是起来调整的。而且, anti-TNF- 抗体经由 caspase-8, caspase-9,和 caspase-3 激活的抑制减轻了导致 Rh2 的 HL-60 房间 apoptosis。另外, TNF- 起来规定也在另外的对待 Rh2 的癌症房间线被观察。这些结果证明 TNF- 在人参皂甙起一个关键作用导致 Rh2 的房间 apoptosis。
Ginsenoside Rh2, a triterpene saponin extracted from Panax ginseng, exhibits pharmacological activity against multiple cancers. However, the anticancer mechanism of ginsenoside Rh2 is unclear. In this study, we found that ginsenoside Rh2 effectively inhibits growth and induces apop- tosis of HL-60 cells. Using microarray technology, we found that tumor necrosis factor-α (TNF-α) is clearly up-regulated. Furthermore, anti-TNF-α antibody relieved the Rh2-induced HL-60 cell apoptosis via suppression of caspase-8, caspase-9, and caspase-3 activation. In addition, TNF-α up-regulation was also observed in other Rh2-treated cancer cell lines. These results demonstrate that TNF-α plays a key role in ginsenoside Rh2-induced cell apoptosis.
