大鼠趋化素样因子2 mRNA在心肌梗死大鼠心脏中的表达

Expression of chemokine-like factor 2 (CKLF2) mRNA in the rat myocardium after myocardial infarction

目的 :观察大鼠趋化素样因子 2 (rCKLF2 )的mRNA在心肌梗死后大鼠心脏组织的表达。方法 :构建大鼠心肌梗死模型 ,分别于心肌梗死后 1d、3d、1周、2周、3周 (每个时间点各 5例 ) ,取心肌梗死周边区心肌组织 ,提取组织总RNA ,逆转录后行竞争性PCR ,了解rCKLF2mRNA的表达情况。结果 :rCKLF2mRNA在梗死心肌周边区的表达于术后上调 ,并呈动态变化 ,1周达峰值 ,为正常的 6 .7倍。结论

Objective: To investigate the expression of chemokine like factor 2 (CKLF2) mRNA in the rat myocardium after myocardial infarction(MI).Methods: In a rat model of MI, the myocardium surrounding the infarcted area was used for RNA preparation at different time points. After RT, competitive polymerase chain reaction amplification was performed to assess the expression of rCKLF2 mRNA. SAS Kruskal Wallis test was used for statistical comparisons. Results: The gene expression of rCKLF2 at mRNA level was significantly increased in the myocardium surrounding the infarcted area 3 days, 1 week, 2 weeks after infarction.Conclusion: It is possible that CKLF2 contributes to the pathophysiological process and needs to be further investigated.
