In response to RFA-AG-20-007, we address the FOA to “facilitate the characterization of the marmoset as a laboratory animal for research on aging and age-related diseases” by leveraging the expertise and resources of the San Antonio Marmoset Aging Program (SA MAP). Over the last decade, the SA MAP has made major contributions to our understanding of the physiological and functional changes that occur in aging marmosets including physiological (metabolism, body composition, etc.), functional (cognitive, cardiovascular, etc.), pathological and molecular. Moreover, the SA MAP is at the forefront of using the marmoset for geroscience and has directed studies to address the effect of aging interventions on marmoset lifespan. The SA MAP has built an interactive group of researchers from different backgrounds to take interdisciplinary approaches to address fundamental questions that exist in the changes that occur with age in the marmoset and to meet our overarching goal to characterize and provide a marmoset resource for geroscience research. Characterization of the marmoset for geroscience, particularly in terms of the hallmarks of aging will provide a valuable preclinical model for translation with explicit definitions on how aging affects identifiable physiological, pathological and cellular/molecular outcomes. Moreover, the marmoset will be a valuable preclinical tool for testing potential intervention strategies in terms of pharmacology, their effects of age-related health and even their effects on longevity in the marmoset prior to human translation. The rationale for this work is that utilization of functional assays will identify biomarkers that can be linked to phenotypic syndromes of aging. Building on our strengths, we will also test the extent to which anti-aging interventions affect outcomes of these functional assays to identify whether they can be utilized as metrics of aging in marmosets. Perhaps most importantly, the SA MAP resources able to be devoted to this study are unmatched elsewhere; the SA MAP maintains ~100 aged and geriatric (from 5-18 yr) marmosets as well as banks of tissue (e.g., kidney, liver, brain) collected from animals across the age range. Our first aim is to elucidate and establish the extent to which chronological marmoset age affects the hallmarks of aging. Our second aim is to determine the extent to which short-term anti-aging interventions alter hallmarks of aging and functional phenotypes in the marmoset to strengthen the foundation for marmosets in geroscience. Our third aim is to expand the synergistic interdisciplinary research team to further develop cutting-edge research. By building synergistic research relationships, it is anticipated that funding of this proposal will both elucidate research findings regarding the marmoset model in geroscience as well as develop the next generation of cutting-edge research using this animal.

为了回应 RFA-AG-20-007，我们向 FOA 提出通过利用圣安东尼奥狨猴衰老计划 (SA MAP) 的专业知识和资源，“促进狨猴作为实验动物的特征，以研究衰老和年龄相关疾病”。在过去的十年中，SA MAP 为我们了解衰老狨猴的生理和功能变化做出了重大贡献，包括生理（代谢、身体成分等）、功能（认知、心血管等）、病理和分子变化。此外，SA MAP 处于利用狨猴进行老年科学的前沿，并指导研究解决衰老干预措施对狨猴寿命的影响。 SA MAP 建立了一个由不同背景的研究人员组成的互动小组，采用跨学科方法来解决狨猴随年龄变化而存在的基本问题，并实现我们的总体目标，即表征狨猴资源并为老年科学研究提供狨猴资源。狨猴在老年科学中的表征，特别是在衰老特征方面，将为翻译提供有价值的临床前模型，并明确定义衰老如何影响可识别的生理、病理和细胞/分子结果。此外，狨猴将成为一种有价值的临床前工具，用于测试药理学方面的潜在干预策略、其对年龄相关健康的影响，甚至在人类翻译之前对狨猴寿命的影响。这项工作的基本原理是，利用功能测定将识别与衰老表型综合征相关的生物标志物。基于我们的优势，我们还将测试抗衰老干预措施对这些功能测定结果的影响程度，以确定它们是否可以用作狨猴衰老的指标。也许最重要的是，能够用于这项研究的 SA MAP 资源在其他地方是无与伦比的； SA MAP 保存着约 100 只老年和老年（5-18 岁）狨猴以及从各个年龄段的动物身上收集的组织库（例如肾脏、肝脏、大脑）。我们的首要目标是阐明并确定狨猴年龄对衰老特征的影响程度。我们的第二个目标是确定短期抗衰老干预措施在多大程度上改变狨猴的衰老特征和功能表型，以加强狨猴在老年科学方面的基础。我们的第三个目标是扩大协同的跨学科研究团队，进一步发展前沿研究。通过建立协同研究关系，预计该提案的资助将阐明老年科学中狨猴模型的研究成果，并利用这种动物开展下一代尖端研究。
