摘要: 目的

基于多组学数据探究奥卡西平靶基因与癫痫基因的相关性,探讨奥卡西平抗痫机制。

方法

借助DrugBank数据库检索奥卡西平靶基因,利用Magama软件及整合单细胞测序数据验证奥卡西平靶基因在全基因组关联分析(genome-wide association study,GWAS)层面与癫痫致病基因的相关性,应用Fisher检验验证奥卡西平靶基因与稀有变异癫痫危险基因存在显著遗传重叠,运用R软件进行奥卡西平靶基因富集,基于DAVID数据库对靶点进行基因本体功能富集分析和京都基因与基因组百科全书信号通路富集分析。

结果

共获得奥卡西平药物靶点25种,主要为钠离子通道、细胞色素P450家族成员、醛酮还原酶家族成员、血清白蛋白、羰基还原酶家族成员。通过癫痫GWAS数据基因集分析,奥卡西平靶基因与癫痫致病基因存在显著关联,且与单基因突变所致癫痫风险基因存在显著重叠,主要为电压门控钠离子通道。通过测序得出奥卡西平富集神经细胞类型主要为下丘脑GABA能神经元和中型多棘神经元。通过靶向富集途径分析,显示奥卡西平药物靶点显著富集在中枢神经系统钠离子通道中。

结论

基于生物信息学整合分析,奥卡西平可能通过作用于下丘脑GABA能神经元、中型多棘神经元中的钠离子通道基因发挥抗痫作用。

Abstract: Objective

To explore the relationship between oxcarbazepine target gene and epileptic gene based on multi-group data, and to explore the antiepileptic mechanism of oxcarbazepine.

Methods

The target gene of oxcarbazepine was searched by DrugBank database. Magama software and integrated single cell sequencing data were used to verify that there was significant association between oxcarbazepine target gene and epileptic pathogenic gene at GWAS level. Fisher test was used to verify that there was significant genetic overlap between oxcarbazepine target gene and rare variant epileptic risk gene. R software was used to enrich oxcarbazepine target gene. Gene ontology function enrichment analysis and Kyoto gene and genome encyclopedia signal pathway enrichment analysis were carried out based on DAVID database.

Results

A total of 25 kinds of oxcarbazepine drug targets were obtained, including sodium channels, cytochrome P450 family members, aldosterone reductase family members, serum albumin and carbonyl reductase family members. Through the gene set analysis of epileptic GWAS data, there is a significant association between oxcarbazepine target gene and epileptic pathogenic gene, and there is a significant "overlap" between oxcarbazepine target gene and epileptic risk gene caused by single gene mutation, which is mainly voltage-gated sodium channel. The main types of neurons enriched by oxcarbazepine were hypothalamic GABA neurons and medium spiny neuron. The analysis of targeted enrichment pathway showed that the drug targets of oxcarbazepine were significantly enriched in the sodium channels of the central nervous system.

Conclusion

Based on bioinformatics integration analysis, oxcarbazepine may play an antiepileptic effect by acting on sodium channel genes in hypothalamic GABA neurons and medium spiny neuron.
