项目摘要
DESCRIPTION (provided by applicant):
Stroke is the third leading cause of mortality and the leading cause of severe disability worldwide. It is a complex disease that results from many different pathologic conditions including atherosclerosis and hypertension and is therefore affected by multiple genetic and environmental factors. Understanding the genetic basis of stroke will allow us to gain a deeper understanding of the mechanisms behind its pathogenesis. As a complex disease trait, the genetic basis of stroke susceptibility can be studied by using quantitative trait loci analysis to identify regions of DNA that are associated with it. In this proposal, we aim to study the susceptibility to cerebral infarction in the presence of focal cerebral ischemia in mice via an integrative strain survey. We hypothesize that susceptibility to cerebral infarction in the presence of ischemia vary among inbred strains of mice and that this phenotypic variability across strains has a genetic basis. We will perform in silico QTL mapping (haplotype association mapping) for inbred strain phenotypes to identify potential chromosomal regions with stroke susceptibility genes. We will integrate the QTL results with that of microarray gene expression analysis and other bioinformatics tools to narrow down the QTL regions for selection of candidate genes causing stroke susceptibility. The single gene analysis will be extended to incorporate probabilistic gene networks. The candidate genes which affect the vulnerability to stroke as predicted by the QTL mapping can be applied to human studies and ultimately lead to therapeutic and predictive tools for cerebral protection in patients with a variety of cerebrovascular diseases.
PUBLIC HEALTH RELEVANCE:
Stroke is a major public health burden. This project uses a mouse model of stroke to examine the genetic basis of stroke susceptibility. This will be accomplished via computational and bioinformatics tools together with the emerging genetics resources.
描述(由申请人提供):
中风是死亡率的第三大主要原因,也是全球严重残疾的主要原因。这是一种复杂的疾病,它来自许多不同的病理状况,包括动脉粥样硬化和高血压,因此受到多种遗传和环境因素的影响。了解中风的遗传基础将使我们能够更深入地了解其发病机理的机制。作为一种复杂的疾病特征,可以通过使用定量性状基因座分析来研究中风易感性的遗传基础,以识别与之相关的DNA区域。在该提案中,我们旨在研究小鼠通过综合菌株调查的局灶性脑缺血的易感性。我们假设在缺血的存在下对脑梗死的易感性在小鼠的杂交菌株之间有所不同,并且这种菌株之间的表型变异性具有遗传基础。我们将对近交菌株表型的硅QTL映射(单倍型关联映射)进行,以鉴定具有中风敏感性基因的潜在染色体区域。我们将将QTL的结果与微阵列基因表达分析和其他生物信息学工具的结果整合在一起,以缩小QTL区域的缩小,以选择引起中风敏感性的候选基因。单个基因分析将扩展以结合概率基因网络。 QTL映射预测的影响中风脆弱性的候选基因可以应用于人类研究,并最终导致各种脑血管疾病患者的脑保护的治疗和预测工具。
公共卫生相关性:
中风是主要的公共卫生负担。该项目使用小鼠中风模型来检查中风敏感性的遗传基础。这将通过计算和生物信息学工具以及新兴的遗传学资源来实现。
