摘要
目的:探讨T淋巴瘤侵袭转移诱导因子1(T-lymphoma invasion and metastasisi nducing proteinI,Tiam1)在早孕小鼠子宫内膜中的表达规律。方法:采用RT-PCR和Western blotting方法分别检测早孕小鼠子宫内膜中Tiam1mRNA和蛋白的表达水平。结果:①Tiam1mRNA的表达量随妊娠天数的增加逐渐增高,到妊娠第5日表达量达到峰值,于妊娠第6日、第7日开始逐渐降低;②Tiam1蛋白表达与其mRNA表达规律基本一致。结论:Tiam1在妊娠早期子宫内膜中持续表达,可能参与小鼠胚胎植入过程。
Objective: To investigate the expression applicability of T-lymphoma invasion and metastasis inducing protein I (Tiaml) in endometria of early pregnant mouse. Methods: The expression of Tiaml mRNA and protein in endometria of early pregnant mice was tested by RT-PCR and Western blotting, respectively. Results: 1) The expression of Tiaml mRNA in endomertria of early pregnant mice was higher than that in non-pregnant mice and it was gradually increased from pregnancy day 2 reaching a maximum level on day 5 and then declining on day 6 and day 7.2) The expression regularity of Tiaml protein was basically as same as that of mRNA. Conclusion: Tiaml is gradually expressed in endometria of early pregnant mouse, and it might play a role in embryo implantation in mouse.
