目的
2
以基质细胞衍生因子-1(Stromal cell-derived factor-1,SDF-1)/趋化因子受体4(Chemokine receptor,CXCR4)生物轴为基础,探讨乳癌术后含药血清对乳腺癌细胞MDA-MB-453增殖和侵袭能力的影响。
方法
2
建立SDF-1诱导的CXCR4高表达MDA-MB-453细胞模型,制备乳癌术后方含药血清及空白大鼠血清。实验分空白组,空白大鼠血清组,SDF-1+空白大鼠血清组,SDF-1+乳癌术后方组,AMD3100+SDF-1+空白大鼠血清组和AMD3100+SDF-1+乳癌术后方组。干预48 h,采用cell counting kit-8(CCK-8)法检测细胞增殖情况,transwell小室实验检测细胞侵袭能力,分别用实时荧光定量聚合酶链式反应(Real-time PCR)和蛋白免疫印迹法(Western blot)检测细胞CXCR4,基质金属蛋白酶(matrix metalloproteinase,MMP)-2,MMP-9 mRNA及蛋白表达情况。
结果
2
与空白血清组比较,SDF-1为100 μg·L
-1
时,MDA-MB-453细胞增殖明显,CXCR4 mRNA表达明显增加(
P
<
0.05);与SDF-1+空白大鼠血清组比较,乳癌术后方能抑制SDF-1诱导的MDA-MB-453细胞增殖、侵袭行为,下调CXCR4,MMP-2,MMP-9 mRNA和蛋白表达水平(
P
<
0.05);经AMD3100预处理24 h,乳癌术后方对MDA-MB-453细胞增殖的抑制作用明显增强(
P
<
0.05);同时,乳癌术后方下调CXCR4,MMP-2,MMP-9 mRNA和蛋白表达的作用明显增加(
P
<
0.05)。
结论
2
乳癌术后方可通过调控SDF-1/CXCR4生物轴,降低MDA-MB-453细胞MMP-2,MMP-9表达,减少细胞外基质(extracellular matrix,ECM)降解,进而抑制乳腺癌细胞转移的发生;与CXCR4抑制剂AMD3100具有协同效应。
Objective
2
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
2
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
2
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
2
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.
