Expression of chemokine receptors,MMPs,and VEGF in pancreatic cancer fibroblast cell lines

  • Online:2016-08-25 Published:2016-09-12

摘要:

目的 探讨趋化因子受体(chemokine receptors,CRs)、基质金属蛋白酶 (matrix metalloproteinases,MMPs)、血管内皮生长因子(vascular endothelial growth factor,VEGF)的表达与胰腺癌肿瘤相关成纤维细胞(cancer associated fibroblasts,CAFs)生物学行为的关系。方法 用原代培养的方法建立胰腺癌CAFs和正常成纤维细胞(normal fibroblasts,NFs)。用Real-time PCR方法检测CRs(CXCR1、CXCR2、CXCR4、CXCR7)、MMPs(MMP1、MMP2、MMP7、MMP9)和VEGF mRNA的表达。结果 成功建立胰腺癌CAFs和正常胰腺NFs。在CAFs和NFs中,趋化因子受体CXCR1、CXCR2、CXCR4、CXCR7 mRNA的表达均存在差异,CAFs表达量高于NFs。其中CXCR2、CXCR4 mRNA在两株细胞中的表达差异具有统计学意义(P=0.010,P=0.049)。MMPs和VEGF mRNA的表达同样存在差异,CAFs中MMP7和VEGF mRNA表达明显高于NFs,差异具有统计学意义(P=0.017,P=0.049);CAFs中MMP9 mRNA的表达明显低于NFs,差异具有统计学意义(P=0.012)。结论 在胰腺癌CAFs中CRs、MMPs和VEGF mRNA的表达有差异,可能与其促侵袭转移能力存在一定的相关性。

Abstract:

Objective To establish cancer associated fibroblast(CAF) lines and normal fibroblast (NF) lines and use them to investigate expression of chemokine receptors,MMPs and VEGF and thereby understand the biological behavior of CAFs in pancreatic cancer. Methods Primary cultures of CAFs and NFs were established,and mRNA levels of chemokine receptors,MMPs and VEGF were measured using RT-PCR. Results Expression of mRNAs encoding the chemokine receptors CXCR1,CXCR2,CXCR4,and CXCR7 was higher in CAFs than in NFs. This difference was statistically significant in the case of CXCR2(P=0.010) and CXCR4(P=0.049). Similarly,MMP7 mRNA was expressed at significantly higher levels in CAFs(P=0.017),as was VEGF(P=0.049). Conversely,MMP9 mRNA levels were significantly higher in NFs(P=0.012). Conclusion Differential expression of chemokine receptors,MMPs and VEGF in CAFs may help explain their aggressive behavior in pancreatic cancer.
