Core B

核心B通过提供对最先进的RNAi工具的访问来支持该计划内的每个项目。短发夹状RNA(ShRNAs)是在该计划的支持下开发的，核心B和计划调查人员正在进行的创新帮助制造了这些极其强大的生物工具。在过去的资助期间，Core设计了快速设计携带受调控shRNA表达盒的小鼠的方法，设计了以多路复用方式对shRNA进行功能验证的策略，并创建了与人类和小鼠的注释蛋白质编码基因相对应的第三代RNAi文库。在即将到来的请求支持期间，核心建议通过五个总体目标来协助方案调查人员。首先，该计划将继续提供对最先进的RNAi工具的访问，用于分析单基因敲除或执行池RNAi筛选。其次，Core将与研究人员合作，操作“传感器分析”，以确定针对感兴趣基因的最佳shRNAs工具。第三，该核心将针对计划研究人员感兴趣的基因集产生定制的RNAi文库。第四，Core将生产携带受监管的RNAi盒式磁带的小鼠，并帮助研究人员将这些与其他所需的遗传损伤结合起来。最后，核心将继续努力改进RNAi技术，并将这些创新提供给该计划和整个社区。

Core B supports every project within the Program by providing access to state-of-the-art RNAi tools. Short hairpin RNAs (shRNAs) were developed with the support of this program, and ongoing innovations by Core B and Program investigators have helped to make these extremely powerful biological tools. During the past funding period, the Core devised methods to rapidly engineer mice carrying regulated shRNA expression cassettes, devised strategies for functionally validating shRNAs in a multiplexed fashion, and created a third generation of RNAi libraries corresponding to annotated protein coding genes in humans and mice. During the upcoming period of requested support, the core proposes to aid Program investigators through five general aims. First, the program will continue to provide access to state-of-the-art RNAi tools for analyzing either single gene knockdowns or for performing pooled RNAi screens. Second, the Core will work with investigators to operate the "sensor assay" to identify optimal shRNAs tools against genes of interest. Third, the core will produce custom RNAi libraries against sets of genes that are of interest to Program investigators. Fourth, the Core will produce mice carrying regulated RNAi cassettes and aid investigators in combining these with other desired genetic lesions. Finally, the Core will carry on its efforts to improve RNAi technologies and make those innovations available to the Program and to the community at large.
