DESCRIPTION (provided by applicant): This application proposes to create an innovative Center of Biomedical Research Excellence (COBRE) focused on the Comparative Biology of Tissue Repair, Regeneration and Aging. Tissue regeneration in mammals is extremely limited. However, robust regeneration is the norm for countless lower vertebrates and invertebrates. In addition, nature has endowed diverse animals with remarkable longevity and robust tissue repair mechanisms that slow aging-induced degenerative processes. The COBRE research theme uniquely focuses on using diverse non-mammalian and mammalian model organisms together with comparative biology approaches to address several overarching and fundamental questions in the field of regenerative biology that can only be addressed at the level of the whole organism. This research focus represents a cornerstone of the long term strategic scientific Vision of the Mount Desert Island Biological Laboratory (MDIBL), and builds on the MDIBL and Maine INBRE success stories and on MDIBL's longstanding and increasingly important expertise in comparative biomedical research. The four proposed COBRE projects have extensive points of intersection and interaction and focus on defining mechanisms of limb and sensory axon regeneration in zebrafish, the impact of aging and somatic mutation load on mouse hematopoietic stem cell tissue homeostasis, and the effects of aging and stress on zebrafish tissue regeneration. Proposed scientific cores will provide essential services and resources to Project Leaders and will be valuable to a larger scientific community. The Comparative Animal Models Core will provide COBRE investigators with resources necessary to utilize diverse non-mammalian animal models in regenerative and aging biology research. The Comparative Functional Genomics Core will provide data management and analysis expertise to COBRE investigators. It will also develop a novel web-based resource that integrates data generated by COBRE investigators with published data sets in order to provide a systems-level view of regeneration that will inform new hypotheses about how genes regulate regenerative responses in diverse organisms. The Administrative Core will provide administrative, scientific, and fiscal leadership; implement a career development plan for junior faculty that facilitates their transition to independence; and implement an evaluation strategy to assess the progress of the COBRE in accomplishing its goals. The proposed COBRE will greatly enhance MDIBL's growth and development, which in turn will contribute to the continued growth and enhancement of the biomedical research infrastructure in Maine.

描述（由申请人提供）：本申请提议创建一个创新的生物医学研究中心（Cobre），该中心侧重于组织修复，再生和衰老的比较生物学。哺乳动物的组织再生非常有限。但是，健壮的再生是无数下脊椎动物和无脊椎动物的规范。此外，自然已经赋予了多种动物，其寿命明显且稳健的组织修复机制缓慢衰老引起的退化过程。鞋底研究主题独特地着重于使用多种非哺乳动物和哺乳动物模型生物以及比较生物学方法，以解决再生生物学领域的几个总体和基本问题，只能在整个生物体的水平上解决。这项研究重点是荒岛山生物实验室（MDIBL）长期战略科学愿景的基石，并建立在MDIBL和缅因州inbre成功案例以及MDIBL在比较生物医学研究方面的长期和越来越重要的专业知识。拟议的四个圆锥形项目具有广泛的交集和相互作用点，并专注于定义斑马鱼中肢体和感觉轴突再生的机制，衰老和体细胞突变负荷对小鼠造血干细胞组织稳态的影响以及衰老和压力对衰老和压力的影响斑马鱼组织再生。拟议的科学核心将为项目领导者提供必不可少的服务和资源，并将对更大的科学界有价值。比较动物模型的核心将为毛cre研究者提供在再生和衰老生物学研究中利用多种非哺乳动物模型的必要资源。比较功能基因组学核心将为毛cor研究者提供数据管理和分析专业知识。它还将开发一种基于Web的新型资源，该资源将Cobre研究者生成的数据与已发表的数据集集成在一起，以提供系统级别的再生视图，该视图将为基因如何调节多种生物的再生反应提供信息。行政核心将提供行政，科学和财政领导；为初级教师实施职业发展计划，以促进他们向独立过渡；并实施评估策略，以评估鞋底实现目标的进度。拟议中的毛线将大大提高MDIBL的增长和发展，这反过来将有助于缅因州生物医学研究基础设施的持续增长和增强。
