DESCRIPTION (provided by applicant): This proposal describes a five year training program to develop an academic career in Cardiology. The principal investigator has completed structured residency training in Medicine at Duke University Medical Center and is completing Cardiology fellowship training at the same institution. Now, he will expand upon his clinical and scientific skills through uniquely developed interdepartmental collaborations and mentoring. This program will develop a new field of study, namely the integration of Drosophila genetics and human cardiovascular disease to identify novel genes that cause dilated cardiomyopathy. Dr. Howard Rockman will mentor the principle investigator's scientific development. Dr. Rockman is a recognized leader in the field of receptor biology and the genetics of cardiomyopathy and heart failure. To enhance the training, the program will include the expertise of Dr. Joseph A. Izatt, Assistant Professor of Biomedical Engineering and Dr. Hubert Amrein, Assistant Professor in Molecular Genetics and Microbiology. In addition, a committee of highly-regarded medical scientists will provide scientific and career advice. Recent work in the laboratories of Drs. Rockman and Izatt has demonstrated that optical coherence tomography can accurately and rapidly detect normal and abnormal cardiac function in awake, adult Drosophila. This proposal hypothesizes that studies employing of Drosophila genetics can lead to the identification of genes causing human dilated cardiomyopathies. The specific aims are to: 1) Investigate the biochemical and genetic mechanisms through which mutations in the decapentaplegic (dpp) / bone morphogenetic protein (BMP) signaling pathway lead to dilated cardiomyopathy in adult Drosophila. 2) Identify novel genes that cause cardiomyopathy through a genome-wide screen of adult Drosophila. 3) Investigate the genetic mechanisms that modify survival and cardiac function in adult Drosophila with dilated cardiomyopathy.

描述（由申请人提供）： 该建议描述了一个五年的培训计划，以发展心脏病学学术职业。 首席研究人员已完成杜克大学医学的结构化住院医师培训 医疗中心，正在同一机构完成心脏病学奖学金培训。现在，他会的 通过独特的跨部门扩展他的临床和科学技能 协作和指导。该计划将开发一个新的研究领域，即果蝇遗传学和人类心血管疾病的整合，以鉴定引起扩张心肌病的新基因。霍华德·洛克曼（Howard Rockman）博士将指导主要研究者的科学发展。 Rockman博士是受体生物学领域的公认领导者，以及心肌病和心力衰竭的遗传学。为了增强培训，该计划将包括生物医学工程助理教授Joseph A. Izatt博士和分子遗传学和微生物学助理教授Hubert Amrein博士。此外，由备受瞩目的医学科学家委员会将提供科学和职业建议。 Drs实验室的最新工作。 Rockman和Izatt证明了光学相干断层扫描可以准确，快速检测出醒着的成年果蝇中的正常和异常心脏功能。该提议假设采用果蝇遗传学的研究可以导致鉴定引起人类扩张心肌病的基因。具体目的是：1）研究脱皮术（DPP） /骨形态发生蛋白（BMP）信号通路中突变的生化和遗传机制，导致成人果蝇的心肌病扩张。 2）鉴定通过成年果蝇全基因组筛选引起心肌病的新型基因。 3）研究通过扩张的心肌病改变成人果蝇的生存和心脏功能的遗传机制。 （抽象的结尾）
