摘要:

目的 从分子水平揭示富亮氨酸重复激酶2(LRRK2)基因G2019S突变帕金森病的发病机制,为临床诊断及治疗提供新思路。 方法 在公共基因芯片数据库(GEO)中下载LRRK2基因G2019S突变帕金森病的相关基因芯片数据(GSE22491),其中LRRK2(G2019S)突变帕金森病样本10 例,正常控制组样本8 例,利用Qlucore Omics Explorer(QOE)3.0 软件、DAVID、STRING等在线分析软件对LRRK2基因G2019S突变帕金森病差异基因进行生物信息学分析。结果 QOE3.0分析筛选出1752个LRRK2基因G2019S突变帕金森病差异基因,其中上调191个,下调1561个。对其进行生物信息学分析发现,SKP2、RBX1、SKP1、CUL1、CUL4A 等基因以及核糖体信号通路、氧化磷酸化信号通路、蛋白酶体信号通路、白细胞跨内皮迁移信号通路、磷酸戊糖途径信号通路、枸橼酸信号通路、Fcγ受体(FcγR)介导的吞噬通路等在LRRK2基因G2019S突变帕金森病的发生发展中可能起着重要作用。 结论 通过生物信息学分析LRRK2基因G2019S突变帕金森病相关基因芯片数据,提示LRRK2基因G2019S突变帕金森病发病是多种基因、多种分子机制相互作用的结果,对相关分子机制的进一步分析有利于揭示LRRK2基因G2019S突变帕金森病的发病机制。

Abstract:

Objective To investigate the genes from Parkinson’s disease (PD) patients carrying the mutation of leucine-rich repeat kinase 2(LRRK2) gene(G2019S)and explore the molecular mechanism of Parkinson’s disease. Methods Microarray dataset GSE22491 from the Gene Expression Omnibus database, the dataset includes 10 PD and 8 control samples, and analyzed by bioinformatics methods using Qlucore Omics Explorer(QOE)3.0,DAVID and String. Results A total of 1752 genes were identified as differentially expressed genes, of which 191 were upregulated and 1561 were downregulated in PD. The main biological pathways involved included ribosome,oxidative phosphorylation, proteasome, Leukocyte transendothelial migration, pentose phosphate pathway, citrate cycle, Fc gamma R-mediated phagocytosis and genes of SKP2、RBX1、SKP1、CUL1、CUL4A etc may plays important roles in the molecular mechanism of Parkinson’s disease. Conclusion The pathogenesis of PD involves multiple genes, and investigations of these genes may provide valuable insights into the mechanism of PD with mutation of LRRK2 gene (G2019).
