摘要
目的:探讨滋养细胞中STAT3信号通路与侵袭性相关因子MMP-9的相关性。方法:应用免疫印迹实验、荧光定量PCR实验分析人绒毛膜滋养层细胞系JEG-3细胞中STAT3活性与MMP-9的表达水平。结果:SD-1008可特异性降低JEG-3中STAT3的磷酸化水平(0.35±0.14倍,Z=-2.201,P=0.028);与对照组相比,SD-1008处理组细胞中MMP-9mRNA(0.48±0.21倍,t=6.104,P=0.002)和蛋白(0.44±0.19倍,t=7.259,P=0.001)的表达水平均降低。结论:STAT3可能作为胞内信号通路的上游因子调节滋养细胞中MMP-9的表达。
Objective: To explore the correlation between STAT3 signal pathway and matrix metalloproteinase -9 (MMP -9) in trophoblast cells. Methods: Western blot and fluorescent quantitative polymerase chain reaction were used to analyze STAT3 activity and MMP-9 expression level in human chorionic JEG- 3 trophoblast cells. Results: SD -1008 reduced the phosphorylation level of STAT3 specifically by (0. 35 ±0. 14) fold (Z = -2. 201 , P =0. 028) ; compared with control group, the expression levels of MMP -9 mRNA and protein in SD- 1008 treatment group decreased by (0. 48 ±0. 21 ) fold and (0.44 ± 0. 19) fold, respectively (t = 6. 104, P = 0. 002; t = 7. 259, P = 0. 001 ) . Conclusion: STAT3 can regulate the expression of MMP - 9 in trophoblast cells as a upstream regulator of intracellu- lar signal pathway.
