초록

Objective: This study is aimed to investigate the anti-tumor metastasis by innate immunomodulating effects of crude polysaccharide isolated from Polygonati Rhizoma (CP-PR) on 4T1 breast cancer cells.


Methods: CP-PR was isolated from Polygonati Rhizoma. Antimetastatic experiments were conducted in vivo mouse model by using 4T1 breast cancer cells. The cell viability of CP-PR was tested with normal spleen and 4T1 breast cancer cells. To observe the activation of macrophages with/without 4T1 breast cancer cells, production of tumor necrosis factor-α (TNF-α), interleukin-6 (IL-6), IL-10 and IL-12 were measured with enzyme-linked immunosorbent assay (ELISA), respectively. In addition, the lysis of YAC-1 cells and the production of granzymes were measured to observe the activation of natural killer (NK) cell.


Results: Intravenous administration of CP-PR significantly inhibited metastasis of 4T1 breast cancer cells. In an in vitro cytotoxicity analysis, CP-PR affected the growth of normal spleen and 4T1 breast cancer cells above specific concentration. The production of TNF-α, IL-6, IL-10 and IL-12 were significantly increased in macrophages with CP-PR. As compared with control, CP-PR showed significantly higher production of TNF-α, IL-10 and IL-12 in macrophages co-cultured with 4T1 breast cancer cells. The lysis of YAC-1 cells and the production of granzymes were significantly up regulated by CP-PR.


Conclusion: CP-PR appears to have considerable activity on the anti-metastasis by activation of innate immune system.
