中文摘要
核心基础设施(动物基础设施)-基础设施项目总结。
--
这一计划的所有研究和项目都将依赖于转基因小鼠基因工程(GEM)的广泛使用。
模型需要进一步研究核转录因子受体、转录因子和它们的共同调节因子的作用和机制。
在能量代谢、动态平衡和疾病方面。更具体地说,至少有34个宝石和小鼠品系将不会被使用。
在今年第一个资助期结束期间,还将有数千只雄性和10只雌性小鼠在家中通过繁育技术进行繁殖。
因此,通过整合这些昂贵的组件,实现核心BPP的这一动物保护组件是实现这一成功的关键。
设备、先进的生产技术、经验丰富的专业人员和丰富的动物资源。初步调查显示。
研究表明,Core已经培育/建立了多个新的宝石品系,并开发了CRISPR-Cas9介导的小鼠。
基因编辑和系统。我们将致力于帮助实现三个主要目标。首先,我们将继续使用它的专业技术。
专业知识、最先进的技术设备和足够的基础设施,足以为所有外国调查人员创造新的宝石生产线。
PP.我们已经建立了必要的新方法,通过同源基因重组来进一步编辑小鼠的基因组--
基于基因靶向技术在胚胎细胞中的作用,或基于CRISPR/Cas9的基因编辑技术在1-细胞小鼠和胚胎中的作用。
为本次设计方案的调查人员提供所需的所有宝石生产线。第二,酷睿公司将不会提供高品质的鼠标。
旨在更好地管理宝石和克隆的服务,并生产出所有适合所有人的基因型定义的小鼠和年龄/性别匹配的小鼠。
调查人员对这一新的PP进行了审查。具体地说,核心B将继续培育和维护本PPP使用的所有34个新的小鼠品系。
核心B基因将继续使用我们的新殖民地基因扩增协议,以生产大量的基因/年龄/性别匹配的雄性小鼠。
试验性胚胎分析。我们还将继续进行基因分型、超排卵、胚胎移植和精子移植。
冷冻保存、体外受精和体外受精服务旨在帮助更多的调查人员了解如何管理他们的小鼠。
群体,除了保存宝石品系,还包括在不同机构之间转移老鼠品系,保护和拯救畜牧业。
费用。最后,核心动物保护计划将整合所有调查人员对动物保护资源最高效的使用效率。
由于世界上最大的鼠标和鼠标模型的大规模运营,以及产品共享的特点,许多鼠标和鼠标的生产线都在其中。
本次PPP的主要项目包括设备、专业技术和宝贵的鼠标资源的集中管理和集成。
对于科学研究的成功和成本效益来说都是必不可少的。核心技术B将不会最大限度地减少动物的总费用。
实验主要是通过巩固设备、专业技术、动物饲养设施和老鼠的使用和管理水平来实现的。
维护和生产。此外,核心项目B也将作为项目执行项目和技术项目培训项目的主要资源库。
所有动物实验操作的使用都是必要的,他们将监督所有实验动物和小鼠的护理和使用。
英文摘要
Core B (Animal Component) - Project Summary
All research projects of this Program Project (PP) will rely on the use of genetically engineered mouse (GEM)
models to investigate the roles and mechanism of Nuclear Receptors, transcription factors and their coregulators
in energy and metabolic homeostasis and disease. More specifically, at least 34 GEM mouse lines will be used,
and thousands of male and female mice will be produced by breeding in house during the funding period of this
PP. Therefore, this Animal Component of Core B is essential for the success of this PP by integrating expensive
equipment, advanced technology, experienced personnel and animal resources. As shown by preliminary
studies, Core B has generated/established multiple GEM lines and developed CRISPR-Cas9-mediated mouse
gene editing systems. Core B is dedicated to achieving 3 major objectives. Firstly, Core B will use its specialized
expertise, state-of-the-art equipment and adequate facilities to generate GEM lines for all investigators of this
PP. Core B has established the necessary methods to edit the mouse genome by homologous recombination-
based gene targeting in ES cells or CRISPR/Cas9-based gene editing in 1-cell mouse embryos. Core B will
generate all GEM lines needed by the investigators of this PP. Secondly, Core B will provide high quality mouse
services to manage GEM line colonies and produce genotype-defined and age/sex-matched mice for all
investigators of this PP. Specifically, Core B will breed and maintain all of the 34 mouse lines used by this PP.
Core B will use our colony expansion protocol to produce large numbers of genotype/age/sex-matched mice for
experimental analysis. Core B also will perform genotype analysis, super ovulation, embryo and sperm
cryopreservation, and in vitro fertilization services to help the investigators of this PP for managing their mouse
colonies, preserving GEM lines, transferring mouse lines between institutes, and saving animal husbandry
expenses. Finally, Core B will integrate the efficient usage of animal resources by all investigators of this PP.
Because of the large-scale operation of mouse models and the sharing features of multiple mouse lines among
the projects of this PP, centralized integration of equipment, expertise and valuable mouse resource will be
essential for both scientific success and cost effectiveness. Core B will minimize the expenses of animal
experiments by consolidating the usage and management of equipment, expertise, animal facility, mouse
maintenance and production. In addition, Core B will serve as a resource for execution and technical training in
the use of all animal manipulations needed and oversee the care and use of experimental mice for this PP.
