项目摘要
DESCRIPTION (provided by applicant): My long-term career goal is to become an independent physician-scientist, focused on applying genomic technologies to better understand cancer. This proposal describes a 5 year training program for the development of an academic career in genomics, cancer and Anatomic Pathology. Through this training program, I will gain new skills in genomics and systems biology and their application to human disease. Dr. Kevin White, who is a leader in the field and Director of the Institute for Genomics and Systems Biology, will mentor my scientific development. Dr. Olufunmilayo I. Olopade, a recognized leader in the breast cancer research, will serve as a co-mentor on this project. She is the director of the Center for Clinical Cancer Genetics and Global Health at the University of Chicago Medical Center. In addition, an advisory committee of highly-regarded medical scientists will provide scientific and career advice. The project I have designed is not an extension of existing projects in the White or Olopade lab; rather I have taken the development of novel technologies and the White's labs expertise in generating and analyzing large datasets and merged it with my knowledge of cancer and disease to establish an independent line of research. I plan use genomic techniques to study human tumors extensively in my own independent lab, so the mentored phase of my training in the White lab will provide me with a critical additional training period in which to learn how to apply cutting edge genomic technologies to cancer. I have proposed a 5-year training period during which I will acquire skills
necessary to become an independent physician-scientist through interactions with my mentors and participation in formal didactics, national meetings and conferences. I will further develop my scientific skills by pursuing a unique cross-disciplinary research training program in Pathology and Genomics and Systems Biology. In addition to expanding my scientific skill set, I will gain experience in other skills necessary to become a successful independent investigator, such as grant writing, mentoring, and lab management. Furthermore, this additional training will give me time to generate and publish enough data to be competitive for R01 funding. This training will propel the me to an independent investigator position with a deep knowledge of cancer, so that I can make valuable contributions to the cancer field. Breast cancer, the second leading cause of cancer death amongst American women, can be divided into multiple subtypes with different biological behaviors, sensitivity to therapy, and survival. These differences in behavior and treatment sensitivities suggest that the development of subtype-specific therapies will lead to more effective treatment. However, the molecular mechanisms responsible for differences in gene expression, biological behavior, and ultimately outcome, between the different subtypes are poorly understood. We hypothesize that clinically relevant differences between breast cancer subtypes are driven by subtype-specific molecular aberrations. We propose to use RNA sequencing to identify these molecular aberrations. RNA-seq will allow us to analyze several processes, including isoform-specific expression, novel fusion genes, and inherited and somatic genetic variants. Thus, RNA-sequencing will allow me to investigate the role of alternative promoter usage, alterative splicing, chromosomal rearrangements, and inherited and acquired genetic variants in disease heterogeneity in breast cancer. However, unlike most cancer sequencing studies, we will not focus solely on acquired mutations. Given the known role of inherited variants in cancer, and the suspected role of rare alleles in complex disease, we regard both inherited and acquired variants with interest. Indeed, our preliminary studies (see Aim 1 and 2) strongly suggest that we can differentiate two subtypes of breast cancer based on shared genetic variation contained largely in rare deleterious alleles, which include both mutations and inherited variants. Furthermore, our preliminary data suggests that we can differentiate breast cancer subtypes based not only by gene expression, but also by isoform usage alone. Having identified isoforms and genetic variants that distinguish breast cancer subtypes, we will determine if these isoforms or genetic variants alter protein function in cell line models. We will then correlate these effects in human tumor tissue. Thus, through this work we expect to develop a better understanding of the mechanisms underlying shared phenotypic behavior within subtypes of breast cancer. Our contribution here is expected to be the identification of molecular mechanisms, pathways, and processes that differentiate ERBC and TNBC. These mechanisms represent subtype-specific drivers of disease and thus potential targets for therapeutic intervention. By identifying and targeting these mechanisms, we will be able to design more effective, subtype-specific therapies for breast cancer. Furthermore, this work will provide important advances in our understanding of the biology underlying disease heterogeneity. The lessons learned here about the contribution of alternative splicing, fusion-genes, rare, inherited variants and somatic mutations to disease heterogeneity will be applicable to many diseases.
描述(申请人提供):我的长期职业目标是成为一名独立的内科科学家,专注于应用基因组技术更好地了解癌症。这份提案描述了一项为期5年的培训计划,旨在发展基因组学、癌症和解剖病理学方面的学术生涯。通过这个培训计划,我将在基因组学和系统生物学以及它们在人类疾病中的应用方面获得新的技能。凯文·怀特博士是该领域的领导者,也是基因组和系统生物学研究所的主任,他将指导我的科学发展。Olufunmilayo I.Olopade博士是乳腺癌研究领域公认的领导者,他将担任该项目的共同导师。她是芝加哥大学医学中心临床癌症遗传学和全球健康中心的主任。此外,一个由备受尊敬的医学科学家组成的咨询委员会将提供科学和职业建议。我设计的项目并不是White或Olopade实验室现有项目的延伸;相反,我利用了新技术的开发和White实验室在生成和分析大型数据集方面的专业知识,并将其与我对癌症和疾病的知识相结合,建立了一条独立的研究路线。我计划在我自己的独立实验室中使用基因组技术来广泛研究人类肿瘤,所以我在白宫实验室的培训指导阶段将为我提供一个关键的额外培训阶段,在这段时间里,我将学习如何将尖端基因组技术应用于癌症。我提出了一个为期5年的训练期,在此期间我将获得技能
通过与我的导师互动,以及参加正式的教学、国家会议和会议,成为一名独立的内科科学家所必需的。我将通过在病理学、基因组学和系统生物学方面进行独特的跨学科研究培训计划来进一步发展我的科学技能。除了扩展我的科学技能之外,我还将在其他必要的技能方面获得经验,以成为一名成功的独立调查员,如拨款撰写、指导和实验室管理。此外,这一额外的培训将使我有时间生成和发布足够的数据,以具有R01资金的竞争力。这次培训将把我推向一个对癌症有深刻了解的独立研究员职位,这样我就可以为癌症领域做出有价值的贡献。乳腺癌是美国女性癌症死亡的第二大原因,可分为多个亚型,具有不同的生物学行为、对治疗的敏感性和存活率。这些行为和治疗敏感性的差异表明,针对亚型的治疗方法的发展将导致更有效的治疗。然而,导致不同亚型之间基因表达、生物学行为和最终结果差异的分子机制尚不清楚。我们假设乳腺癌亚型之间的临床相关差异是由亚型特有的分子异常所驱动的。我们建议使用RNA测序来鉴定这些分子畸变。RNA-SEQ将使我们能够分析几个过程,包括异构体特异性表达,新的融合基因,以及遗传和体细胞遗传变异。因此,RNA测序将使我能够研究替代启动子的使用、选择性剪接、染色体重排以及遗传和获得性遗传变异在乳腺癌疾病异质性中的作用。然而,与大多数癌症测序研究不同,我们不会只关注获得性突变。鉴于遗传变异在癌症中的已知作用,以及稀有等位基因在复杂疾病中的可疑作用,我们对遗传和获得性变异都很感兴趣。事实上,我们的初步研究(见目标1和2)强烈表明,我们可以根据共同的遗传变异区分两种亚型的乳腺癌,这些变异主要包含在罕见的有害等位基因中,包括突变和遗传变异。此外,我们的初步数据表明,我们不仅可以根据基因表达情况区分乳腺癌亚型,还可以仅通过亚型使用来区分乳腺癌亚型。在确定了区分乳腺癌亚型的异构体和遗传变异后,我们将确定这些异构体或遗传变异是否会改变细胞系模型中的蛋白质功能。然后,我们将在人类肿瘤组织中关联这些效应。因此,通过这项工作,我们希望更好地理解乳腺癌亚型中共同表型行为的潜在机制。我们在这里的贡献是识别区分ERBC和TNBC的分子机制、途径和过程。这些机制代表了疾病的亚型特异性驱动因素,因此是治疗干预的潜在目标。通过识别和定位这些机制,我们将能够设计出更有效的、针对乳腺癌亚型的治疗方法。此外,这项工作将为我们理解疾病异质性的生物学基础提供重要的进展。在这里学到的关于选择性剪接、融合基因、罕见的遗传变异和体细胞突变对疾病异质性的贡献将适用于许多疾病。
