项目摘要

ABSTRACT Specific aims/significance. In our well-characterized baboon nonhuman primate (NHP) models of developmental programming and aging we use both categorical group and longitudinal, life course approaches to evaluate interactive programming-aging mechanisms. Developmental programming can be defined as responses to challenges in critical developmental time windows that alter life course phenotype. Premises/hypotheses. 1. Aging antecedents are present early in the hippocampal-hypothalamo-pituitary- adrenal (HHPA) axis (HHPAA), brain, and behavior; cardiovascular system (CVS); and metabolism. 2. Programming-aging interactions are major determinants of life course HHPA, brain, behavior, CVS, and metabolic health span. 3. Comparing normative, life course observational control data with data from three interventions that alter aging trajectory provides insights into key aging mechanisms and cellular pathways and information needed for translation to humans to anticipate age-related mechanisms that either increase or decrease health span. Findings enable development of markers and beneficial interventions in human aging. Projects - 1. HHPAA, Brain, and Behavior. 2: CVS Function. 3: Metabolism. Cores - A: Administrative; B: Animal; C: Genomics; D: MRI; E: Samples and Data Management. Synergy: All components study all 96 animals with in vivo MRI and tether studies and in vitro histological, cell culture, and molecular approaches. We study 96 baboons in 4 groups, equal males and females at 6–17 years (y) (human equivalent ~18–68y; 24– 68% of the life course). Groups: 1. 48 normal life course controls (NLC); 2. 16 IUGR offspring (F1) of moderately undernourished mothers; 3. 16 F1 of obese, over-nourished mothers; 4. In 16 at 12–17y we clamp plasma cortisol to normal 5y levels. Comparison of aging mechanisms in NLC and interventions provides information on life course whole animal and cellular mechanisms modified by programming-aging interactions. New preliminary data. We present new evidence of increased cortisol and accelerated brain, CVS, and metabolic aging in IUGR. Responsiveness to PAR-16-143 Complex Integrated Multi-Component Projects in Aging Research (U19). We address requested “Large-scale longitudinal observational studies… integration of multiple outcomes with molecular, genetic, mechanistic data and interventions… animal models for aging- related conditions… multiple endpoints to elucidate mechanisms.” Investigators are from multiple institutions and have worked and published together in aging research and programming and in completing large NIH P01s, R24s, P51s. We share resources worldwide. Innovation. Life course NHP studies are rare. We assembled unique cohorts and built our own custom facility for these studies. We now 1. perform biopsies not euthanasia, enabling further applications on these cohorts; 2. combine U19 in vivo and in vitro data with histological and molecular data from our extensive fetal (130 fetuses) and postnatal archives (120 adults birth to 25y) to produce a new mechanistic programming and aging framework from womb to tomb.
摘要 具体目标/意义。在我们充分表征的狒狒非人灵长类动物(NHP)模型中, 发展规划和老龄化,我们使用分类组和纵向,生命过程的方法 评估交互式编程老化机制。发展规划可以定义为 在关键发育时间窗口中对挑战的反应,改变生命过程表型。 前提/假设。1.衰老的前因存在于大脑的早期-下丘脑-垂体- 肾上腺(HHPA)轴(HHPAA),大脑和行为;心血管系统(CVS);和代谢。2. 编程-老化相互作用是生命过程HHPA、大脑、行为、CVS和 代谢健康寿命。3.比较规范性、生命过程观察性对照数据与来自三个 改变衰老轨迹的干预措施提供了对关键衰老机制和细胞途径的见解, 翻译成人类所需的信息,以预测与年龄相关的机制, 降低健康寿命。研究结果使人类衰老的标志物和有益的干预措施的发展成为可能。 项目- 1.
