项目摘要

DESCRIPTION (provided by Project Leader): Brain tumors are the most common group of solid malignancies in children, causing devastating mortality and morbidity in a very understudied patient population. The goal of this program project is to improve understanding and treatment of pediatric brain tumors. During the first funding period, Project leaders worked together to develop novel mouse models that provided key biological insights into cerebellar growth regulation and medulloblastoma development, used these models for relevant preclinical testing of new therapeutic agents, and translated research results into clinical trials. The current application expands the focus of the program to encompass additional pediatric brain tumors. Five interactive projects plan directed studies of growth regulation in the brain using human tumors and mouse models to study signal transduction, gene expression and function in the context of pediatric brain tumors and brain development. An Administrative Core, a Bioinformatics and Biotechnology Core and a Neuropathology Core provide essential support to all projects. In Project 1, S. Baker investigates the molecular pathogenesis of pediatric high-grade glioma taking advantage of a large collection of primary tumors and novel mouse models for glioma that she developed. In Project 2, T. Curran investigates the mechanism of action of a small molecule inhibitor of Hedgehog signaling that he showed ablated medulloblastoma in his model systems. In Project 3, R. Gilbertson will define molecular subgroups of medulloblastoma through analysis of human tumors and development of mouse models, and will characterize cancer stem cells and their niches in subclasses of medulloblastoma. In Project 4, P. McKinnon will further his analysis of defective DNA damage response underlying brain tumor development and will determine the effects of DNA repair inhibitors as a therapeutic approach for brain tumors. In Project 5, M. Roussel and C. Sherr will explore mechanisms of oncogenic transformation in medulloblastoma, and will define microRNAs that modulate gene expression in cerebellar development and medulloblastoma. Integrated analyses within the group will identify common and unique signal transduction pathways in pediatric brain tumorigenesis.

描述（由项目负责人提供）：脑肿瘤是儿童中最常见的实体恶性肿瘤，在研究不足的患者群体中造成毁灭性的死亡率和发病率。该计划项目的目标是提高对儿童脑肿瘤的认识和治疗。在第一个资助期间，项目负责人共同开发了新型小鼠模型，为小脑生长调节和髓母细胞瘤发展提供了关键的生物学见解，使用这些模型进行新治疗药物的相关临床前测试，并将研究结果转化为临床试验。目前的申请扩大了该计划的重点，涵盖更多的儿科脑肿瘤。五个互动项目计划利用人类肿瘤和小鼠模型直接研究大脑的生长调节，以研究儿科脑肿瘤和大脑发育背景下的信号转导、基因表达和功能。行政核心、生物信息学和生物技术核心以及神经病理学核心为所有项目提供必要的支持。在项目 1 中，S. Baker 利用大量原发性肿瘤和她开发的新型神经胶质瘤小鼠模型，研究了儿童高级神经胶质瘤的分子发病机制。在项目 2 中，T. Curran 研究了 Hedgehog 信号小分子抑制剂的作用机制，他在模型系统中显示出消融的髓母细胞瘤。在项目 3 中，R. Gilbertson 将通过分析人类肿瘤和开发小鼠模型来定义髓母细胞瘤的分子亚组，并将描述癌症干细胞及其在髓母细胞瘤亚类中的定位。在项目 4 中，P. McKinnon 将进一步分析脑肿瘤发展背后的缺陷 DNA 损伤反应，并将确定 DNA 修复抑制剂作为脑肿瘤治疗方法的效果。在项目 5 中，M. Roussel 和 C. Sherr 将探索髓母细胞瘤的致癌转化机制，并将定义调节小脑发育和髓母细胞瘤中基因表达的 microRNA。该小组内的综合分析将确定儿科脑肿瘤发生中常见和独特的信号转导途径。
