DESCRIPTION (provided by applicant): Excess consumption of ethanol (alcohol) imposes serious problems for human health and has major negative economic impact worldwide, and in the US and Russia especially. A predisposition towards alcohol overconsumption has a genetic component, and the discovery of the genes involved may lead to better control of alcohol consumption. Animal models can provide an efficient tool for discovering such genes. The long-term goal of the parent project is to positionally clone genes affecting voluntary ethanol consumption in C57BL/6ByJ (B6) and 129P3/J (129) mice. This involves developing congenic mouse strains to isolate genetic loci affecting ethanol consumption, and characterizing their behavioral responses to ethanol. The goals of the FIRCA proposal are to optimize experimental procedures and to conduct a comprehensive analysis of chemosensory perception of ethanol in the two parental strains, B6 and 129. To achieve this, we will characterize several aspects of chemosensory responsiveness to ethanol: hedonics, sensitivity, and taste quality perception. We will also examine the contribution of the gustatory, olfactory and trigeminal sensory inputs to the chemosensory responses elicited by ethanol. The most informative tests will then be used to study congenic and consomic mice created in the parent project. These experiments will test the hypothesis that differences between B6 and 129 mice in voluntary ethanol consumption depend in part on differential chemosensory perception of ethanol. The proposed studies will also elucidate the chemosensory modalities responsible for this differential perception. This will help us to elucidate mechanisms underlying the effects of the genetic loci, which will be useful for identification of corresponding candidate genes. Gene identification in mice will be followed by examination of the role of their human orthologs in future studies. This project will set the stage for a long-term collaboration between scientists at the Monell Center and the Pavlov Institute, and will help to build research capabilities at the Pavlov Institute. This research will be done primarily in Russia at the Pavlov Institute of Physiology of the Russian Academy of Sciences in collaboration with Dr. Zolotarev as an extension of the NIH grant # R01 AA011028 of Dr. Bachmanov. Relevance to public health: The goal of this project is to discover genes affecting alcohol consumption, which will lead to better understanding and control of alcohol abuse.

描述（由申请人提供）：乙醇（酒精）的过度消费对人类健康造成严重问题，并在全球范围内产生重大负面经济影响，尤其是在美国和俄罗斯。过度饮酒的倾向有遗传因素，发现相关基因可能会更好地控制饮酒。动物模型可以为发现这些基因提供有效的工具。母项目的长期目标是定位克隆影响C57 BL/6 ByJ（B6）和129 P3/J（129）小鼠自愿乙醇消耗的基因。这涉及开发同类小鼠品系以分离影响乙醇消耗的遗传位点，并表征其对乙醇的行为反应。FIRCA提案的目标是优化实验程序，并对两种亲本菌株B6和129中乙醇的化学感觉进行全面分析。为了实现这一目标，我们将表征几个方面的化学感受器对乙醇的反应：享乐，敏感性和味觉质量感知。我们还将研究的贡献味觉，嗅觉和三叉神经感觉输入乙醇引起的化学感觉反应。然后，将使用信息量最大的试验研究母项目中创建的同类和同源小鼠。这些实验将测试的假设，即B6和129小鼠之间的差异，在自愿的乙醇消费量部分取决于不同的化学感觉知觉的乙醇。拟议的研究还将阐明负责这种差异感知的化学感觉方式。这将有助于我们阐明遗传位点的作用机制，这将有助于识别相应的候选基因。在小鼠中的基因鉴定之后，将在未来的研究中检查其人类直系同源物的作用。该项目将为莫内尔中心和巴甫洛夫研究所的科学家之间的长期合作奠定基础，并将有助于建立巴甫洛夫研究所的研究能力。这项研究将主要在俄罗斯科学院巴甫洛夫生理学研究所与Zolotarev博士合作进行，作为Bachmanov博士的NIH资助#R 01 AA 011028的延伸。与公共卫生的相关性：该项目的目标是发现影响酒精消费的基因，这将导致更好地了解和控制酒精滥用。
