BACKGROUND
Ginsenoside Rg3 is an extract from the natural product ginseng. Previous studies have linked Rg3 with anti-metastasis of cancer in vivo and in vitro. CXC receptor 4 (CXCR4) is a vital molecule in migration and homing of cancer to the docking regions.
METHODS
In this study, the effects of Rg3 on CXCR4 expression were investigated in a breast cancer cell line. Immunohistochemistry, chemotaxis and wound healing mobility assays were performed in cultured MDA-MB-231 cells.
RESULTS
At a dosage without obvious cytotoxicity, Rg3 treatment elicits a weak CXCR4 stain color, decreases the number of migrated cells in CXCL12-elicited chemotaxis and reduces the width of the scar in wound healing.
CONCLUSIONS
This work suggests that Rg3 is a new CXCR4 inhibitor from a natural product.
