项目摘要

Project Abstract: The overall goals of this project are to establish and pursue an innovative approach combining discovery studies in mammalian systems with translational and functional studies in the powerful genetic model organism Drosophila melanogaster as a novel strategy to identify and characterize genes and proteins underlying the behavioral changes that occur during the development of psychosis. In the search for new medical therapies, and in particular treatments for disorders of the central nervous system involving serotonin, like schizophrenia, psychosis, and depression, there has been increasing recognition that identification of a single biological target is unlikely to be a recipe for success; a broader perspective is required. Systems biology is one such approach, and has been increasingly recognized as a crucial and dynamic area of research, as it places specific molecular targets within a context of overall biochemical action. Understanding the complex interactions between the components within a given biological system that lead to modifications in output, such as changes in behavior, may be important avenues of discovery to identify new therapies. Within this framework, our underlying hypothesis is that molecular events, such as gene expression changes, influenced by aberrant serotonin receptor activation in specific regions of the brain, represent molecules that directly participate in, or regulate signal transduction networks that underlie normal cognitive processes that when perturbed lead to neuropsychiatric disorders. Here, we propose a series of experiments following a systems based approach to determine the functional and behavioral role of specific genes and proteins that respond to pharmacological activation of specific neurotransmitter receptors in the prefrontal cortex of rat brain in a proposed animal model of the neurochemical and genetic events underlying psychosis and schizophrenia. We will: 1) Identify additional, and perhaps more relevant, genes and proteins in specific regions of the rat prefrontal cortex through functional genomic, proteomic, and gene expression analysis; 2) Examine the functional role of these genes and proteins in behaviors in translational studies in the fruit fly, Drosophila melanogaster. We strongly believe that this multidisciplinary systems-based approach combining mammalian CNS pharmacology and whole animal studies in our powerful genetic Drosophila model, is the best route to follow to achieve our goals. Significantly, our results may lead to novel avenues for therapeutics to treat such devastating diseases as schizophrenia and psychosis.

项目摘要：该项目的总体目标是建立和采用一种创新的方法结合在哺乳动物系统中具有转化和功能研究的哺乳动物系统研究遗传模型生物果蝇果蝇作为识别和表征基因的新策略以及在精神病发展过程中发生行为变化的基础的蛋白质。在寻找新的医疗疗法，特别是治疗中枢神经的疾病涉及5-羟色胺的系统，如精神分裂症，精神病和抑郁症，有所增加认识到，识别单个生物学靶标的不太可能成为成功的秘诀。一个需要更广泛的观点。系统生物学就是一种这样的方法，并且越来越多被认为是研究的至关重要和动态领域，因为它将特定的分子靶标放在整体生化作用的背景。了解组件之间的复杂相互作用在给定的生物系统中，导致产出的修改（例如行为变化）可能成为发现新疗法的重要途径。在这个框架内，我们的基础假设是分子事件（例如基因表达变化）受异常5-羟色胺的影响大脑特定区域中的受体激活表示直接参与或参与的分子调节基于正常认知过程的信号转导网络导致神经精神疾病。在这里，我们提出了一系列基于系统的实验确定特定基因和蛋白质的功能和行为作用的方法大鼠脑前额叶皮层中特定神经递质受体的药理激活提出的神经化学和遗传事件的动物模型以及精神病和遗传事件的模型精神分裂症。我们将：1）确定更多的，甚至更相关的基因和蛋白质大鼠前额叶皮层的特定区域通过功能基因组，蛋白质组学和基因表达分析； 2）检查这些基因和蛋白质在行为中的功能作用果蝇中的翻译研究，果蝇Melanogaster。我们坚信这个将哺乳动物CNS药理学和整体的多学科基于系统的方法结合在我们强大的遗传果蝇模型中的动物研究是遵循我们的最佳途径目标。值得注意的是，我们的结果可能导致治疗这种毁灭性的治疗方法的新途径疾病作为精神分裂症和精神病。
