摘要
目的检测核酸切除修复交叉互补基因1(ERCC1)在急性缺血性脑卒中(CIS)患者的表达,探讨ERCC1基因与急性CIS的关系。方法收集64例急性CIS患者(卒中组)和70例体检健康者(对照组)外周血样和临床资料。实时荧光定量PCR检测ERCC1基因mRNA在外周血单个核细胞(PBMCs)的相对表达水平,ELISA检测ERCC1蛋白在血浆中的表达水平。结果卒中组ERCC1基因mRNA表达水平显著低于对照组(P<0.05),蛋白表达水平显著高于对照组(P<0.05)。不同卒中类型ERCC1基因mRNA和蛋白表达水平差异均无统计学意义(P>0.05)。ERCC1基因mRNA表达水平与中风史呈负相关(r=-0.409,P=0.013),其蛋白表达水平与之无明显相关性(P>0.05)。结论 ERCC1基因可能参与急性CIS的发生、发展、转归及复发。
Objective The expression level of nucleotide excision repair cross complementing 1(ERCC1)was detected in acute cerebral ischemic stroke(CIS)patients for discussing the relationship between ERCC1 and acute CIS.Methods The peripheral blood samples and clinical data were collected from 64 patients with acute CIS(the stroke group)and 70 healthy controls(the control group).The relative expression level of ERCC1 mRNA in peripheral blood mononuclear cells(PBMCs)was detected by real-time quantitative PCR,and the ERCC1 protein level in plasma was detected by enzyme-linked immunosorbent assay(ELISA).Results The relative expression level of ERCC1 mRNA in the stroke group was lower than that in the control group(P<0.05).The protein level was significantly higher than that in the control group(P<0.05).There was no significant difference on ERCC1 mRNA or protein expression level among different stroke types(P>0.05).There was a negative correlation between ERCC1 mRNA and the history of stroke(r=-0.409,P=0.013).However,there was no significant correlation between the protein expression level and the history of stroke(P>0.05).Conclusion ERCC1 might be related to the occurrence,development,prognosis and recrudescence of acute CIS.
