This application is a request for a NIAAA Mentored Patient-Oriented Research Career Development Award (K23). Alcoholism is a complex, genetically influenced disorder the cause of which may be better understood through the study of genetically influenced phenotypes that mediate the risk. Alcohol exerts many of its effects via interactions with receptors for the amino acid gamma-aminobutyricacid (GABA), including GABAA receptors, which are formed by the assembly of five subunit proteins and are involved in the reinforcing effects of alcohol. Because differences in sensitivity to alcohol is a risk factor for the development of alcohol use disorders, this study will determine if genetic variation in GABAA -receptor subunit genes mediate, in part, the observed variance in sensitivity to alcohol in a healthy social-drinking population (Specific Aim 1). To test this hypothesis, the time course of subjective and physiological effects obtained repeatedly before and following acute alcohol ingestion will be determined. Specific Aim 2 will determine if genetic variations in GABAA-receptor subunit genes associated with differences in sensitivity to alcohol (as determined in Specific Aim 1) are also associated with alcohol dependence. This hypothesis will be tested using an established DMAdataset collected from a large population of alcohol-dependent and control subjects.This research will expand our understanding of one possible mechanism by which risk of alcoholism may be transmitted. It is hoped that such knowledge will contribute to future pharmacogenetic approaches in the screening and management of alcohol use disorders. The candidate's career development plan is set in a multidisciplinary environment and includes: conducting mentored research in the project described above, developing expertise in human subjects research techniques, acquiring experience in the application of psychological assessment scales, learning laboratory techniques, and gaining skills in genetic analysis. Although the candidate is a well-trained neuroendocrinologist, she requires mentored training to hone skills as an alcohol researcher with a special interest in human genetics. The candidate's long term career goal is to become an independent clinical investigator in the field of alcohol use disorders with expertise in genetics. Specifically, the candidate aspires to make significant contributions to understanding the multifactorial pathogenesis of alcohol abuse and dependence and its translational application to treating these disorders.

该应用程序是NIAAA指导的以患者为导向的研究职业发展奖 （K23）。酒精中毒是一种复杂的，受遗传影响的疾病，可以更好地理解其原因 通过研究介导风险的遗传影响的表型。酒精施加了许多 通过与氨基酸γ-氨基丁酸（GABA）的受体相互作用的影响，包括 GABAA受体，由五种亚基蛋白组装而成，并参与 加强酒精的影响。因为对酒精的敏感性差异是发展的危险因素 酒精使用障碍，这项研究将确定GABAA - 受体亚基基因的遗传变异是否存在 在健康的社交饮食人群中，部分调解了观察到的对酒精敏感性的差异 （特定目标1）。为了检验这一假设，获得的主观和生理效应的时间过程 将在急性摄入之前和之后反复确定。特定目标2将确定是否 与酒精敏感性差异相关的GABAA受体亚基基因的遗传变异（AS 在特定目标中确定1）也与酒精依赖性有关。该假设将进行检验 使用已建立的DMADATASET，这些Dmadataset从大量的酒精依赖和对照中收集 主题。这项研究将扩大我们对酒精中毒风险的一种可能机制的理解 可以传输。希望这种知识将有助于未来的药物遗传学方法 酒精使用障碍的筛查和管理。候选人的职业发展计划已制定 一个多学科环境，包括：在上述项目中进行指导研究， 在人类受试者研究技术方面发展专业知识，获得了应用的经验 心理评估量表，学习实验室技术以及在遗传分析中获得技能。 尽管候选人是训练有素的神经内分泌学家，但她需要进行指导的培训来磨练技能 作为对人类遗传学特别感兴趣的酒精研究人员。候选人的长期职业目标是 成为具有遗传学专业知识的酒精使用障碍领域的独立临床研究者。 具体而言，候选人渴望为理解多因素做出重大贡献 酒精滥用和依赖性的发病机理及其在治疗这些疾病中的转化应用。
