This subproject is one of many research subprojects utilizing the resources provided by a Center grant funded by NIH/NCRR. The subproject and investigator (PI) may have received primary funding from another NIH source, and thus could be represented in other CRISP entries. The institution listed is for the Center, which is not necessarily the institution for the investigator. Significant progress was made during the current funding period on the completion of this study. Socio-environmental factors significantly affect the risk for developing a number of behavioral and psychiatric disorders in people, including anxiety, depression, eating disorders, and addiction. It is becoming increasingly clear that some individuals are more susceptible to developing these pathologies and that this increased risk may be attributed to genetic factors. While identifying genetic/environment influences on behavior presents practical challenges and ethical constraints in people, rhesus monkeys represent an ideal model to begin to identify the genetic contribution to such disorders. The goal of this project is to conduct an analysis of the genetic heritabilities of a number of biobehavioral and physiological traits that are relevant for psychiatric disorders, followed by linkage and association analysis of candidate genes and gene polymorphisms that account for individual differences in these characteristics using the pedigreed rhesus monkey population living in large social groups at the Field Station. In the past year we completed the collection of the behavioral and physiological samples on the animals. These data included behavioral measures of sociality and aggression, anthropometric measures of body weight, height, BMI, and serum hormone measures of leptin, insulin, triiodothyronine, thyroxin, glucose, and cortisol; and CSF measures of monoamines, CRH, vasopressin, cortisol, and oxytocin. As of Jan 2010, we are awaiting the final results of the CSF analyzes at which point we will begin the heritability analyzes. This project represents a unique opportunity to conduct a translational, behavioral genetics study of candidate genes that predispose individuals to the adverse consequences associated with behavioral and psychiatric disorders, including anxiety and depression.

这个子项目是许多利用 由NIH/NCRR资助的中心赠款提供的资源。子项目和 研究者（PI）可能从另一个NIH来源获得了主要资金， 因此可以在其他CRISP条目中表示。列出的机构为 中心，但不一定是研究者所在的机构。 在本供资期间，在完成这项研究方面取得了重大进展。 社会环境因素会显著影响人们发生许多行为和精神障碍的风险，包括焦虑、抑郁、饮食失调和成瘾。 越来越清楚的是，有些人更容易患上这些疾病，这种增加的风险可能归因于遗传因素。 虽然识别遗传/环境对行为的影响对人类提出了实际挑战和道德约束，但恒河猴代表了开始识别遗传对此类疾病的贡献的理想模型。 该项目的目标是对与精神疾病相关的一些生物行为和生理特征的遗传遗传性进行分析，然后对候选基因和基因多态性进行连锁和关联分析，这些基因和基因多态性解释了这些特征中的个体差异，使用生活在野外站大型社会群体中的纯种恒河猴种群。 在过去的一年里，我们完成了动物行为和生理样本的收集。 这些数据包括社交性和攻击性的行为测量，体重、身高、BMI的人体测量，以及瘦素、胰岛素、三碘甲状腺原氨酸、甲状腺素、葡萄糖和皮质醇的血清激素测量;以及单胺、CRH、加压素、皮质醇和催产素的CSF测量。 截至2010年1月，我们正在等待CSF分析的最终结果，届时我们将开始遗传力分析。 这个项目代表了一个独特的机会，进行一个翻译，行为遗传学研究的候选基因，使个人倾向于与行为和精神疾病，包括焦虑和抑郁相关的不良后果。
