Abstract

|
|
Purpose: This study was carried out to investigate the anti-tumor metastasis effect and activation of innate immunity by extracts of Mori radicis cortex.
Methods: Anti-tumor metastatic experiment was conducted in vitro and in vivo by using colon 26-M3.1 carcinoma cell, L5178Y-R lymphoma cell and HeLa cell. To observe the activation of innate immunity by extracts of Mori radicis cortex, we estimated IL-6, IL-10, IL-12, TNF- from peritoneal macrophages. And we evaluated the activation of NK cell by using anti-asialo-GM1 serum.
Results: We found that the administration of Mori radicis cortex extracts significantly inhibited tumor metastasis. In an in vitro cytotoxicity analysis, Mori radicis cortex affected tumor cell growth above specific concentration. Mori radicis cortex also stimulated peritoneal macrophage, which was followed by the production of various cytokines such as IL-6, IL-10, IL-12, TNF-. The depletion of NK cells by anti-asialo GM1 serum partly abolished the inhibitory effect of Mori radicis cortex on tumor metastasis.
Conclusion: Mori radicis cortex appears to have considerable activity on the anti-metastasis by activation of innate immunity.
