The use of transgenic mice has been instrumental in the characterization and understanding of the genetic basis of mammalian development and physiology. The genetics group at Yale University in particular has utilized transgenic mice to study the evolution of the HOX genes that are essential for normal development, the role of the transcription factor AP-2 in vertebrate morphogenesis, and the role of T-cells in immune system function and development, among other projects. This proposal requests funds to augment the transgenic mouse facility at Yale University. The facility presently has one old transgene injection set-up and one modern set-up for blastocyst injection of stem cells. The transgene apparatus is now 20 years old and despite mechanical wear and tear is used at capacity. This project proposes to add a new transgene injection station, to repair and upgrade the existing apparatus, and to add ancillary equipment that will generally support the overall program in transgene research and education. As transgene techniques continue to expand, the facility comes under even greater use by the faculty and students at Yale. The sheer volume of experimental studies necessitates the acquisition of new instrumentation. New instruments will enhance the efficiency of both research and teaching activities. Additional equipment will also make possible the development of new techniques such as the controlled expression of transgenes, fluorigenic reporter constructs, and the modification of endogenous genes by "knock-in" procedures. The requested equipment will be accessible to a broad spectrum of investigators and students both within and outside of Yale University. Access if facilitated by housing the equipment in an Animal Research Facility managed by a consortium of faculty investigators rather than within a single investigator's group. The facility is self- contained and integrates both animal care and housing and transgene laboratory space.

转基因小鼠的使用有助于表征和理解哺乳动物发育和生理学的遗传基础。 耶鲁大学的遗传学小组特别利用转基因小鼠研究了正常发育所必需的HOX基因的进化，转录因子AP-2在脊椎动物形态发生中的作用，以及T细胞在免疫系统功能和发育中的作用等项目。 该提案要求提供资金，以扩大耶鲁大学的转基因小鼠设施。 该设施目前有一个旧的转基因注射装置和一个用于干细胞胚泡注射的现代装置。 转基因装置现在已经有20年的历史了，尽管有机械磨损，但仍在全力使用。 该项目建议增加一个新的转基因注射站，修复和升级现有设备，并增加辅助设备，以支持转基因研究和教育的整体计划。 随着转基因技术的不断发展，耶鲁大学的教职员工和学生越来越多地使用该设施。 大量的实验研究需要购置新的仪器。 新的工具将提高研究和教学活动的效率。 额外的设备也将使新技术的发展成为可能，如转基因的控制表达，荧光报告结构，以及通过“敲入”程序修饰内源基因。 所要求的设备将提供给耶鲁大学内外的广泛的调查人员和学生。 如果将设备存放在由研究人员组成的联盟管理的动物研究机构中，而不是在单个研究者小组内，则可促进访问。 该设施是独立的，并整合了动物护理和住房和转基因实验室空间。
