项目摘要

SUMMARY: ANIMAL CORE (CORE D) Investigations into brain tumor biology and therapy are best carried out in orthotopic animal models that mimic the natural milieu of the tumor. The ability to reach meaningful conclusions from these in vivo studies is greatly enhanced when uniform, readily reproducible animal models are used. The core also provides support for investigators using genetically engineered mouse models (in particular the RCAS/Ntv-a model). The purpose of the Animal Core is to provide an animal modeling service that centralizes expertise thereby achieving uniformity and reproducibility that permits accurate comparisons between experiments, research groups, and projects in this Brain Cancer SPORE. In the current funding period, the Animal Core performed 546 experiments involving over 15,000 animals for SPORE investigators. In the next 5-year funding period, the Animal Core will continue to provide expert services to all investigators in Brain Cancer SPORE. To this end, the Core will: 1) Provide support for orthotopic animal experiments using patient-derived glioma stem cell lines (GSCs), which are currently considered the gold standard in vivo model of human gliomas. This Core has developed approximately 100 GSCs, over 40 of which have been fully molecularly characterized; 2) Provide support for flank and orthotopic animal experiments using patient-derived tumor explants from the operating room implanted into NOD.Cg-PrkdcscidIl2rgtm1Wjl/SzJ (NSG) mice; 3) Provide support for animal experiments using immunocompetent genetically engineered mouse models (GEMMs), particularly the RCAS/Ntv-a system; 4) Provide support for orthotopic animal experiments testing oncolytic adenoviruses using immunocompetent hamster models that are permissive to viral replication; 5) Provide support for orthotopic animal experiments using traditional profession glioma cell lines from humans (U87, U251, LN229) and mice (GL261); 6) Provide support for in vivo imaging either with bioluminescence imaging (BLI) or magnetic resonance imaging (MRI) to assess efficacy of therapeutic strategies. These services are mission critical and one or more of these services are used by all Projects in this SPORE.

摘要：动物核心（核心D）对脑肿瘤生物学和治疗的研究最好是在模仿的原位动物模型中进行的肿瘤的天然环境。从这些体内研究中得出有意义的结论的能力是极大的当使用均匀，容易再现的动物模型时，增强了。核心还提供了支持研究人员使用基因工程的小鼠模型（特别是RCAS/NTV-A模型）。目的动物核心是提供一种集中专业知识的动物建模服务，从而实现统一性和可重复性，可以在实验，研究小组和项目之间进行准确比较这个脑癌孢子。在当前的资金期间，动物核心进行了546个实验，涉及超过15,000只孢子调查人员的动物。在接下来的5年资金期间，动物核心将继续为脑癌孢子中的所有研究人员提供专家服务。为此，核心将： 1）使用患者衍生的神经胶质瘤干细胞系（GSC），为原位动物实验提供支持，目前被认为是人类神经胶质瘤的体内金标准模型。这个核心有开发了大约100个GSC，其中40多个已完全分子表征。 2）使用来自患者衍生的肿瘤外植体的侧翼和原位动物实验的支持手术室植入了NOD.CG-PRKDCSCIDIL2RGTM1WJL/SZJ（NSG）小鼠； 3）使用免疫能力的基因工程小鼠模型为动物实验提供支持（GEMMS），特别是RCAS/NTV-A系统； 4）提供了使用免疫能力的原始动物实验测试溶瘤腺病毒的支持允许病毒复制的仓鼠模型； 5）使用传统的专业胶质瘤细胞系为原位动物实验提供支持人类（U87，U251，LN229）和小鼠（GL261）； 6）为生物发光成像（BLI）或磁共振的体内成像提供支持成像（MRI）评估治疗策略的功效。这些服务至关重要，这些服务中的一个或多个服务均由该孢子中的所有项目使用。
