项目摘要

DESCRIPTION (provided by applicant): This application is for a renewal of a NIDA sponsored K02 (DA13926) Independent Scientist Award. The current K02 award (2002-2007) allowed the PI to develop her independent research career that focuses on genetic programming for the expression of drug receptors, in particular, the opioid receptors. It is known that the amounts of opioid receptors are crucial for the analgesic effects of opioid compounds. The control is through genetic programming that instructs the cells to express these genes properly and specifically (transcriptional control) and to produce these proteins from mRNAs (post-transcriptionally) according to the needs. In the previous studies, the major task was to dissect the basic elements responsible for transcriptional and post-transcriptional regulation of opioid receptor genes, that include determining DMA sequences and protein factors required for transcriptional control, identification of post-transcriptional events that modulate the rate, the place and the time of opioid receptor protein production in neurons, and dissecting fundamentally important mechanisms in their regulation. Over the period of 2002-2005 supported by this K02, the Pi's works were published in 35 papers. The renewal proposal will continue systemic investigation into the mechanistic basis of these biological processes and the integration in the animals for understanding the homeostatic control of opioid receptor expression. Thus, the overall direction of the research project remains the same. Specific aims are: 1) to extend studies of transcriptional regulation of KOR gene by focusing on how transcription factors interact with chromatin of the KOR gene, leading to chromatin remodeling of the promoter regions; 2) to identify post-transcriptional events that regulate KOR protein production in neurons by focusing on the control of mRNA transport and local translation in neurons regulated by the 5'- and the 3'-untranslated regions; and 3) to produce transgenic mouse models to answer whether and how these regulatory events affect the manifestation of pharmacological effects and problems of opioids, such as addiction and tolerance. These studies are clinically important for the identification of crucial steps in genetic programming of opioid receptor expression that may shed light on potential targets of interventions for drug abuse problems, and are fundamentally applicable for the understanding of critical biological processes required for neuronal compartment-specific expression of proteins that are of significant pharmacological and neurological consequences. This award is also essential for the Pi's continual career development as an independent scientist in the field of drug abuse research.
描述(由申请人提供):本申请是NIDA赞助的K 02(DA 13926)独立科学家奖的续期。目前的K 02奖(2002-2007)允许PI发展她的独立研究生涯,重点是药物受体表达的遗传编程,特别是阿片受体。已知阿片样物质受体的量对于阿片样物质化合物的镇痛作用至关重要。控制是通过遗传编程,指导细胞正确和特异性地表达这些基因(转录控制),并根据需要从mRNA(转录后)产生这些蛋白质。在以往的研究中,主要任务是剖析负责阿片受体基因转录和转录后调控的基本元件,包括确定转录控制所需的DMA序列和蛋白质因子,鉴定调节神经元中阿片受体蛋白质产生的速率、地点和时间的转录后事件,并剖析其调节中的重要机制。在2002年至2005年期间,由这个K 02支持,Pi的作品发表在35篇论文中。更新提案将继续系统研究这些生物学过程的机制基础和动物中的整合,以了解阿片受体表达的稳态控制。因此,研究项目的总体方向保持不变。具体目标是:1)通过关注转录因子如何与KOR基因的染色质相互作用,导致启动子区域的染色质重塑,扩展KOR基因转录调控的研究; 2)通过关注5 '和3'非翻译区调控的mRNA转运和神经元中的局部翻译,鉴定调节神经元中KOR蛋白产生的转录后事件;以及3)产生转基因小鼠模型以回答这些调节事件是否以及如何影响阿片类药物的药理作用的表现和问题,例如成瘾和耐受。这些研究对于确定阿片受体表达的遗传编程中的关键步骤具有临床重要意义,这些步骤可能揭示药物滥用问题干预措施的潜在目标,并且从根本上适用于理解具有重要药理学和神经学后果的蛋白质的神经元隔室特异性表达所需的关键生物学过程。这个奖项也是必不可少的Pi的持续职业发展作为一个独立的科学家在药物滥用研究领域。
