项目摘要

TRANSGENIC AND KNOCKOUT SHARED RESOURCE PROJECT SUMMARY The main purpose of the Mayo Clinic Cancer Center Transgenic and Knockout (TKO) Shared Resource is to assist investigators at all 3 sites with the design and the generation of genetically modified mouse models. Utilization of the resource has been strong with 49 Cancer Center members from 8 different Programs using the Shared Resource during the current funding period (2013-2017). Our services include CRISPR/Cas9 mediated editing of genes of interest in fertilized mouse eggs to generate knockout and knock-in mouse models to inactivate or tag it, or to introduce point mutations, reporter genes, loxP sites or large deletions. Although gene editing by CRISPR/Cas9 is incredibly useful, in some instances it is not as robust as conventional gene targeting in embryonic stem (ES) cells, prompting us to maintain our classical services mainly to insert large (>5 kb) DNA fragments and loxP sites. Additional services offered by the TKO Core include founder screening, founder breeding, sperm cryopreservation, recovery of cryopreserved mouse strains through in vitro fertilization, and standard histopathology. TKO Shared Resource staff also provide advice on DNA preparation, mouse genotyping, handling and husbandry. To stay at the cutting edge of genome editing, the TKO devotes time and effort to develop or implement innovative and experimental procedures. The above activities allow Cancer Center members to implement state-of-the-art mouse models to address key open questions in the field of cancer etiology and to design and test new therapeutic approaches that improve cancer treatment outcome. The TKO Shared Resource achieved a score of Outstanding at the previous site visit.

转基因和敲除共享资源项目摘要梅奥诊所癌症中心转基因和基因敲除 (TKO) 共享资源的主要目的是协助所有 3 个地点的研究人员设计和生成转基因小鼠模型。资源利用率很高，来自 8 个不同项目的 49 名癌症中心成员使用当前资助期间（2013-2017）的共享资源。我们的服务包括 CRISPR/Cas9 介导编辑小鼠受精卵中感兴趣的基因以产生基因敲除和基因敲入小鼠模型使其失活或标记，或引入点突变、报告基因、loxP 位点或大缺失。尽管 CRISPR/Cas9 基因编辑非常有用，但在某些情况下它不如胚胎干 (ES) 细胞中的传统基因靶向，促使我们维持我们的经典服务主要是插入大的（>5 kb）DNA片段和loxP位点。 TKO 核心提供的附加服务包括创始人筛选、创始人繁育、精子冷冻保存、冷冻小鼠恢复通过体外受精和标准组织病理学鉴定菌株。 TKO 共享资源工作人员还提供关于 DNA 制备、小鼠基因分型、处理和饲养的建议。为了保持在最前沿基因组编辑，TKO 投入时间和精力来开发或实施创新和实验程序。上述活动使癌症中心成员能够实施最先进的小鼠模型解决癌症病因学领域的关键开放问题并设计和测试新的治疗方法改善癌症治疗结果。 TKO 共享资源在之前的现场访问。
