项目摘要

DESCRIPTION (provided by applicant): The original five-year INIA West has identified a large number of candidate genes that are differentially expressed in the brains of mice selectively bred for either high- or low-preference for alcohol. Additional conserved genes were identified in screens for alcohol tolerance in Drosophila. Manipulating the expression of these genes has naturally become a critical component of studies designed to further define their role in the development of alcohol preference or tolerance. The RNA Interference Core (RNAi Core) will provide a means for systematic modification of the target genes' expression in selected and precisely-defined brain areas. Two technological platforms for in vivo RNA interference will be employed: (1) small interfering RNA (siRNA) delivered by a direct injection or infusion into the CNS and (2) short hairpin RNA (shRNA) delivered via a lentiviral vector-based transduction. Initially, these methods will be standardized using transcripts identified in HAP and LAP mice as contributing to alcohol preference drinking behavior, and the functional consequences of the RNAi treatment will be assessed in these mice. The successful implementation of the methodology will provide an important resource for all INIA investigators, including those working with rat models. At the time of this submission, laboratories from California, Colorado, Indiana, Oregon and Texas are already collaborating in both Binge and Dependence Domains. The core will also perform RNAi treatments for INIA investigators, who will develop need for RNAi services with the emergence of additional target genes. Proposed projects will be evaluated for integration with INIA West goals by a Project Evaluation Committee composed of members of the INIA Steering Committee and an independent consultant. The core will capitalize on our ongoing collaboration with Dharmacon Corporation, a leader in the field of siRNA development. Dharmacon will provide many of the necessary reagents and work with us on improving the efficiency of gene silencing in the CNS. The core's goals will be accomplished by successful completion of the following aims: Aim 1. Perform high throughput in vitro screening of the RNAi sequences targeting the genes of interest. Aim 2. Silence expression of selected genes in vivo employing RNAi within precise neuroanatomical targets. Aim 3. Examine behavioral and transcriptional effects of gene silencing. The creation of the RNAi core is a logical extension of the work already completed by the INIA. The core will allow for systematic and high throughput manipulation of genes in the mammalian CNS, facilitating functional studies of these genes in alcohol preference.

描述（由申请人提供）：最初的五年Inia West已确定了大量的候选基因，这些基因在小鼠的大脑中差异表达，选择性地繁殖了针对酒精的高偏见或低选择性。在果蝇中鉴定出其他保守基因，以确保果蝇中的酒精耐受性。操纵这些基因的表达自然已成为旨在进一步定义其在酒精偏好或耐受性发展中的作用的研究的关键组成部分。 RNA干扰核心（RNAi核心）将为靶基因在所选和精确定义的大脑区域中的表达提供系统修饰的手段。将采用两个用于体内RNA干扰的技术平台：（1）通过直接注射或输注到CNS中输送的小型干扰RNA（siRNA），以及（2）通过基于慢病毒载体的转导传递的短发夹RNA（SHRNA）。最初，这些方法将使用在HAP和LAP小鼠中鉴定的转录本进行标准化，以促进酒精偏爱饮酒行为，并且将在这些小鼠中评估RNAi治疗的功能后果。该方法的成功实施将为所有INIA调查人员，包括使用RAT模型的人提供重要资源。在此提交时，来自加利福尼亚，科罗拉多州，印第安纳州，俄勒冈州和德克萨斯州的实验室已经在狂欢和依赖领域都在合作。核心还将为INIA研究人员进行RNAi治疗，他们将随着其他靶基因的出现而发展RNAi服务的需求。由INIA指导委员会成员和独立顾问组成的项目评估委员会和独立顾问组成的项目评估委员会将对拟议的项目进行评估。核心将利用我们与Sirna Development领域领导者Dharmacon Corporation进行的持续合作。佛法将提供许多必要的试剂，并与我们一起提高中枢神经系统中基因沉默的效率。核心的目标将通过成功完成以下目的来实现：目标1。对针对感兴趣基因的RNAi序列进行高吞吐量。目标2。在精确神经解剖靶标内采用RNAi的体内所选基因的沉默表达。目标3。检查基因沉默的行为和转录效应。 RNAi核心的创建是INIA已经完成的工作的逻辑扩展。该核心将允许对哺乳动物中枢神经系统中基因的系统和高吞吐量操纵，从而促进这些基因在酒精偏爱中的功能研究。
