ABSTRACT – BIOSPECIMENS CORE The Biospecimens Core will serve as a central resource to coordinate provision of highly translationally relevant animal and human analytical specimens for use in both main research projects and likely several of the anticipated pilot projects. To maximize the translation relevance of the analyses performed on animal specimens, patient-derived xenografts (PDXs) and genetically engineered mouse models (GEMMs) of glioblastoma (GBM) will be used for our pre-clinical studies. We have extensive experience using these models for evaluating the systems biology of intracranial tumors and how pharmacologic manipulations dysregulate critical signaling nodes within these systems. Coupled with these preclinical studies, analysis of operative specimens from GBM patients provides a ‘ground-truth’ for the biological modeling performed. In this context, the Biospecimens Core will capitalize on established collaborations with neurosurgeons at both DFCI and Mayo Clinic and the extensive Neuro-Oncology Biobank available at Mayo Clinic for provision of both archived tumor samples and prospective analysis of image-registered, fresh operative specimens. Derivative cell, organoid, and tissue-slice cultures from both animal and human biospecimens also will be used to enable reverse translation of key findings and to further refine or validate our systems analyses. To capitalize on opportunities for coordinated analyses of the same biological samples across both Projects, a Scientific Manager will coordinate biospecimen collection, quality assurance review, shipment and analyses across laboratories and projects. The Core also will ensure appropriate regulatory review and approvals are in place to support both the animal and human biospecimen collections and analyses. The overall efforts of the Core can be divided into two Aims to support animal and human GBM studies. Specific Aim 1: Develop, manage, and execute in vivo studies in tumor-bearing animals Specific Aim 2: Coordinate the collection and distribution of human biospecimens

摘要 - 生物测量核心 Biospecimens Core将作为协调高度翻译的核心资源 相关的动物和人类分析标本，用于两个主要研究项目，可能有几个 预期的飞行员项目。为了最大化对动物进行的分析的翻译相关性 标本，患者衍生的Xenographictic（PDXS）和基因工程的鼠标模型（GEMM） 胶质母细胞瘤（GBM）将用于我们的临床前研究。使用这些模型，我们有丰富的经验 用于评估颅内肿瘤的系统生物学以及药物操纵如何失调 这些系统中的关键信号节点。加上这些临床前研究，分析运行 GBM患者的标本为进行的生物建模提供了“基地真相”。在这种情况下， Biospecimens核心将利用DFCI和 Mayo诊所和广泛的神经肿瘤生物库可在Mayo Clinic提供两个存档 肿瘤样品和图像注册的新鲜操作标本的前瞻性分析。衍生细胞， 从动物和人类生物测量中的器官和组织片培养物也将用于实现 关键发现的反向翻译，并进一步完善或验证我们的系统分析。大写 在这两个项目中对相同生物样品进行协调分析的机会，这是科学的 经理将协调生物循环收集，质量保证审查，运输和分析 实验室和项目。核心还将确保适当的监管审查和批准 支持动物和人类生物循环收集和分析。核心的总体努力 可以分为两个目标，以支持动物和人类GBM研究。 特定目的1：在肿瘤动物中开发，管理和执行体内研究 特定目标2：协调人类生物测量的收集和分布
