摘 要: | 目的:探讨TGF-β1作用于口腔鳞癌侵袭转移的关系。方法:采用发色底物反应法测量不同浓度TGF-β1作用于口腔磷癌TSCCa细胞系及颈淋巴转移癌GNM细胞系u-PA和PAI-1的活性。结果:不同浓度的TGF-β1作用于TSCCa12h后,u-PA和PAI-1活性与对照组相比,无明显差异(P>0.05);而不同浓度的TGF-β1作用于GNM细胞12h后,u-PA和PAI-1活性与对照组相比,有显著性差异(P<0.05-0.01),u-PA和PAI-1活性与TGF-β1有剂量依赖关系。结论:TGF-β1可能与口腔鳞癌侵袭转移有关。

Transforming growth gactor beta 1 modulates activity of urokinase plasminogen activator and plasminogen activator inhibitor-1 in oral squamous cell carcinoma and metastatic carcinoma cell lines |

Abstract: | Objective:To study the role of transforming growth factor β1(TGF-β1) on the invasiveness and metastasis of human oral squamous cell carcinoma (OSCC).Methods:Chromogenic substrate assay was used to determine the activity of urokinase plasminogen activator(u-PA) and plasminogen activator inhibitor-1(PAI-1) in OSCC cell line TSCCa and metastatic carcinoma cell line GNM treated with various concentrations of TGF-β1.Results:TGF-β1 at 0.5~5.0 ng/L had no effect on the activity of u-PA and PAI-1 in TSCCa cells (P>0.05);while TGF-β1 at the same concerntrations increased the activity of u-PA and PAI-1 in GNM cells (P<0.05).Conclusion:TGF-β1 may be a factor associated with invasive and metastatic potential of OSCC. |
