项目摘要

Project Summary. Obesity causes substantial social, economic and health burdens. The rate of obesity is escalating disproportionately in children (infants to young adults). This rapid increase is unlikely to be due to environment or genetics alone. Accumulating evidence from our laboratory and others suggests that adult metabolic diseases originate in utero, and likely occur through the reprogramming of gene expression via epigenetic changes in chromatin structure (an altered "histone code"). Of interest, we have observed in a rodent transgenerational model of intrauterine growth restriction (IUGR) that a diet supplemented with essential nutrients, yet unaltered in its caloric content, prevents adult metabolic disease and is associated with abrogation of reprogrammed gene expression. However, although such established models in rodents demonstrate that fetal alterations in the histone code are involved in the persistence and conveyance of the altered postnatal phenotype, little is known about the effects of maternal diet and resultant obesity on primate fetal biology. We hypothesized that a high fat diet in non-human primates would induce changes in hepatic chromatin structure resulting in altered expression of fetal genes critical to the development of childhood and adult obesity. Based on our preliminary data, the focus of this proposal is to apply developed high throughput technology (comparative epigenomics and metabolomics) to decipher the primate epigenome and metabolome in the obese maternal environment and then measure the impact of supplementation on the differentially altered epigenome and resultant disease. The novel innovation and significance resides within its potential to provide (1) an expanded understanding of the mechanism through which a maternal high fat diet reprograms primate gene expression and (2) a simple intervention (essential nutrient supplementation with neither diet nor behavioral modification) with tremendous potential impact given the current obesity epidemic and the lack of efficacious therapeutics.

项目摘要。肥胖造成巨大的社会、经济和健康负担。肥胖率是在儿童（婴儿到年轻人）中不成比例地增加。这种快速增长不太可能是由于环境或基因本身。从我们实验室和其他实验室积累的证据表明，代谢疾病起源于子宫内，并且可能通过基因表达的重编程而发生，染色质结构的表观遗传变化（改变的“组蛋白密码”）。有趣的是，我们观察到，宫内生长受限（IUGR）的啮齿动物跨代模型，即饮食中补充必需的营养素，但其热量含量不变，可预防成人代谢疾病，并与废除重编程基因表达。然而，尽管在啮齿动物中建立了这种模型，表明胎儿组蛋白编码的改变参与了胚胎发育的持续和传递。出生后表型的改变，对母体饮食和由此产生的肥胖对灵长类动物的影响知之甚少。胎儿生物学我们假设非人灵长类动物的高脂肪饮食会诱导肝脏的变化，染色质结构导致对儿童发育至关重要的胎儿基因表达改变，成人肥胖症根据我们的初步数据，该建议的重点是应用开发的高通量技术（比较表观基因组学和代谢组学），以破译灵长类动物表观基因组和代谢组在肥胖的母亲环境中，然后测量补充剂对不同的改变的表观基因组和由此产生的疾病。新的创新和意义在于它的潜力，提供（1）对母体高脂肪饮食重新编程机制的扩展理解灵长类基因表达和（2）简单的干预（既不饮食也不补充必需营养素），行为改变），考虑到目前肥胖的流行和缺乏有效的治疗方法。
