Abstract:
Objective:To investigate the effect of Ru′ai Shuhou prescription （RSR） drug-containing serum on the proliferation and invasion ability of breast cancer cells MDA-MB-453 based on the biological axis of stromal cell-derived factor-1（SDF-1）/chemokine receptor 4 （CXCR4）. Method:A model of MDA-MB-453 cells with SDF-1-induced high expression of CXCR4 was established， and the rat drug-serum containing RSR and blank rat serum were prepared respectively. The cells were divided into fetal bovine serum control group （Blank）， blank rat serum group， SDF-1+blank rat serum group， SDF-1+RSR group， AMD3100+ SDF-1+blank rat serum group， and AMD3100+ SDF-1+RSR group. After intervention for 48 h， cell proliferation was detected by cell counting kit-8 （CCK-8） assay， cell invasion ability was detected by transwell assay， and mRNA and protein expressions of CXCR4， matrix metalloproteinase-2 （MMP-2） and MMP-9 were detected by Real-time fluorescence quantitative polymerase chain reaction （Real-time PCR） and Western blot， respectively. Result:As compared with the blank serum group， the proliferation of MDA-MB-453 cells was promoted and expression of CXCR4 mRNA was increased significantly when SDF-1 was 100 μg·L-1 （P<0.05）. As compared with SDF-1+blank rat serum group， RSR inhibited the proliferation and invasion of MDA-MB-453 cells induced by SDF-1， and at the same time， down-regulated the mRNA and protein expressions of CXCR4， MMP-2 and MMP-9 （P<0.05）. After pre-treatment with AMD3100 for 24 h， the inhibitory effect of RSR to cell proliferation was significantly increased （P<0.05）， and meanwhile， the decreases in mRNA and protein expression of CXCR4， MMP-2 and MMP-9 were more obvious， with statistically significant differences （P<0.05）. Conclusion:Through SDF-1/CXCR4 biological axis， RSR could down-regulate the expression of MMP-2 and MMP-9， reduce the degradation of extracellular matrix （ECM）， and then inhibit the metastasis of MDA-MB-453 cells. In addition， it has a synergistic effect with CXCR4 inhibitor AMD3100.
