项目摘要

 DESCRIPTION (provided by applicant): This proposal describes a five-year training program for mentored career development in academic cardiovascular medicine for Dr. Rajat Gupta. Dr. Gupta is an Instructor at Harvard Medical School and prior trainee of the NIH-sponsored T32 training grant at Brigham and Women's Hospital (BWH) and a Sarnoff Fellow. He has completed clinical training in Cardiovascular Medicine and Internal Medicine through American Board of Internal Medicine. He is now embarking on a research and career development program under the co-mentorship of Drs. Sekar Kathiresan and Kiran Musunuru at the Broad Institute and BWH. Both mentors are leaders in the field of cardiovascular genetics, have a track record of collaboration and mentorship, and are enthusiastic about supporting Dr. Gupta's training and independence in functional genomics and vascular biology. Dr. Gupta's career development plan includes educational resources at Harvard Medical School, the Broad Institute, and the expertise of three leading vascular biologists (Dr. Peter Libby, Dr. Charles Lowenstein, and Dr. Thomas Michel) as advisory committee members to foster his development as an independent vascular biology researcher with training in the genetics of coronary artery disease. Hands-on training in genome-editing technology and histopathologic assessment of atherosclerosis will be supported by the Senior Advisory Committee and expert collaborators in these areas. Additional career development support is provided by the BWH Division of Cardiovascular Medicine, where the PI will serve as attending physician, and the Broad Institute Cardiometabolic Group. He has developed a clear timeline for publication of his work, presentations at national meetings, and the development of independent research projects and funding. Dr. Gupta has worked to identify non-lipid genetic determinants of coronary artery disease and myocardial infarction (CAD/MI). With an international consortium of collaborators he has contributed to the identification of over 50 loci associated with CAD/MI, many of which have an effect on vascular biology. Dr. Gupta has identified 6p24 as one such interesting locus for functional analysis, and has published data identifying the causal variant (rs9349379) and causal gene-phosphatase and actin regulator 1 (PHACTR1). PHACTR1 is expressed in vascular tissue, and preliminary data show an important role in endothelial cell function. Dr. Gupta's primary goals are to determine 1) the importance of the causal variant, rs9349379, on gene expression using edited induced pluripotent stem cells, 2) the role of PHACTR1 in atherosclerosis- relevant endothelial cell function, and 3) the role of PHACTR1 in atherosclerotic vascular disease. Towards these goals Dr. Gupta will utilize innovative approaches such as genome editing in induced pluripotent stem cells and primary vascular cell lines, confocal and live-cell microscopy of endothelial cell migration, and in vivo histopathological assessment of atherosclerosis in a PHACTR1 knockout mouse. Going forward, Dr. Gupta will use these skills and to build a career as an independent, academic physician scientist.
 描述(由申请人提供):本提案描述了一个为期五年的培训计划,为Rajat Gupta博士提供学术心血管医学方面的职业发展指导。古普塔博士是哈佛医学院的讲师,也是布里格姆妇女医院(BWH)NIH赞助的T32培训补助金的前实习生和Sarnoff研究员。他通过美国内科医学委员会完成了心血管医学和内科医学的临床培训。他现在正在布罗德研究所和BWH的Sekar Kathiresan和Kiran Musunuru博士的共同指导下开展研究和职业发展计划。两位导师都是心血管遗传学领域的领导者,有着合作和指导的良好记录,并热衷于支持古普塔博士在功能基因组学和血管生物学方面的培训和独立性。Gupta博士的职业发展计划包括哈佛医学院、布罗德研究所的教育资源,以及三位领先的血管生物学家(Peter Libby博士、Charles Lowenstein博士和托马斯米歇尔博士)作为咨询委员会成员的专业知识,以促进他作为一名独立的血管生物学研究人员的发展,并接受冠状动脉疾病遗传学方面的培训。基因组编辑技术和动脉粥样硬化组织病理学评估方面的实践培训将得到高级咨询委员会和这些领域的专家合作者的支持。BWH心血管医学部提供额外的职业发展支持,PI将担任主治医生,以及Broad Institute Cardiometabolic Group。他为出版他的作品、在国家会议上的演讲以及独立研究项目和资金的发展制定了明确的时间轴。 Gupta博士致力于确定冠状动脉疾病和心肌梗死(CAD/MI)的非脂质遗传决定因素。他与一个国际合作者联盟合作,鉴定了50多个与CAD/MI相关的基因座,其中许多基因座对血管生物学有影响。Gupta博士已经将6p 24确定为一个用于功能分析的有趣位点,并已发表了鉴定致病变体(rs 9349379)和致病基因-磷酸酶和肌动蛋白调节因子1(PHACTR 1)的数据。PHACTR 1在血管组织中表达,初步数据显示在内皮细胞功能中起重要作用。Gupta博士的主要目标是确定1)因果变异rs 9349379对使用编辑的诱导多能干细胞的基因表达的重要性,2)PHACTR 1在动脉粥样硬化相关内皮细胞功能中的作用,以及3)PHACTR 1在动脉粥样硬化血管疾病中的作用。为了实现这些目标,Gupta博士将利用创新方法,如诱导多能干细胞和原代血管细胞系的基因组编辑,内皮细胞迁移的共聚焦和活细胞显微镜,以及PHACTR 1敲除小鼠动脉粥样硬化的体内组织病理学评估。展望未来,古普塔博士将利用这些技能,并建立一个独立的,学术的医生科学家的职业生涯。
