项目摘要

PROJECT SUMMARY Intra-tumoral heterogeneity in human cancers is associated with poor treatment response and prognosis. Head and neck squamous cell carcinoma (HNSCC) is a strikingly heterogeneous tumor, with over 550,000 new cases per year. Unfortunately, this heterogeneity represents a major challenge in targeted therapy and treatment responses, with detailed maps of intra-tumoral heterogeneity just starting to be defined. During my Ph.D. training with Dr. Azad Bonni, I studied normal processes of brain development using sophisticated biochemistry techniques 1,2,3,4, which inspired me to understand the signaling pathways that drive specific biological programs. I applied these skills to studies of glioma, ultimately, defining a dual role for the transcription factor STAT3 as a tumor suppressor and an oncogene 5,6,7. For my post-doctoral training, I joined the laboratory of Dr. Bradley Bernstein, an expert in transcription, epigenetics, and innovative technology, to combine my interests in tumor heterogeneity with my clinical interests in head and neck surgical oncology. Using single cell RNA-seq, we defined the first atlas of HNSCC, identifying a partial epithelial-to-mesenchymal (p-EMT) program associated with lymph node metastasis, lymphovascular invasion, and extracapsular extension8. We also refined tumor subtyping from bulk RNA-seq approaches such as the Cancer Genome Atlas by leveraging our single cell profiles. The objectives of this proposal are to (1) determine expression heterogeneity within 2D and 3D head and neck cancer models and identify suitable models of p-EMT, (2) investigate the regulatory influence of cancer-associated fibroblasts and their ligands on malignant cancer cell states, including the underlying transcriptional and epigenetic mechanisms, and (3) define the signaling pathways downstream of p-EMT and discern their functional importance in tumor behaviors. Dr. Tim Ley and Dr. Greg Longmore are exceptional mentors with an extensive history of trainees in major academic positions. Dr. Ley is an internationally renowned leader in oncology, genomics, and tumor biology, with appointments including Associate Director of the Siteman Cancer and the McDonnell Genome Institute at Washington University St. Louis (WUSTL), National Cancer Advisory Board Member, and former Chair of Board of Scientific Counselors for National Institute Genome Research Institute. Similarly, Dr. Greg Longmore is a world expert in molecular oncology, EMT, and cell biology, with appointments as Co-Director of Molecular Oncology and Director of the Integrating Communications within the Cancer Environment Institute, WUSTL. An exceptional Research Advisory Committee (RAC) will provide additional guidance, including Dr. Ting Wang, Dr. Jose Zevallos, and Dr. Rob Mitra. The K08 award will provide me with the ideal opportunity to succeed in my career goals. The detailed training plan includes a RAC and development of technical/leadership skills that will be invaluable for a transition to independence. Research will be carried out at WUSTL, a prestigious research institute that fosters collaboration, emphasizes intellectual exchange, and boasts unparalleled facilities.

项目总结人类癌症中肿瘤内的异质性与治疗反应和预后不良有关。头颈部鳞状细胞癌(HNSCC)是一种异质性很强的肿瘤，有超过55万新病例每年。不幸的是，这种异质性是靶向治疗和治疗的主要挑战。反应，肿瘤内异质性的详细地图才刚刚开始定义。在我的博士培训期间我和阿扎德·邦尼博士一起，使用复杂的生物化学研究了大脑发育的正常过程技术1、2、3、4，这启发了我理解驱动特定生物程序的信号通路。我将这些技术应用于胶质瘤的研究，最终确定了转录因子STAT3作为一种肿瘤抑制因子和癌基因5，6，7。在博士后培训期间，我加入了布拉德利博士的实验室伯恩斯坦，转录、表观遗传学和创新技术方面的专家，结合了我对肿瘤的兴趣异质性与我在头颈外科肿瘤学的临床兴趣。使用单细胞rna-seq，我们确定了HNSCC的第一个图谱，确定了与之相关的部分上皮到间充质(p-EMT)程序伴有淋巴转移、淋巴管侵犯和包膜外侵犯。我们还提炼了肿瘤利用我们的单个细胞从批量RNA-SEQ方法(如癌症基因组图谱)中进行亚型分型配置文件。该建议目的是(1)确定2D和3D头部内的表达异质性 (2)研究肿瘤相关成纤维细胞及其配体对恶性肿瘤细胞状态的调节影响，包括潜在的转录调控和表观遗传机制，以及(3)确定p-EMT下游的信号通路并区分其在肿瘤行为中的功能重要性。蒂姆·莱伊博士和格雷格·朗莫尔博士都是杰出的导师，他们有广泛的专业实习生历史学术立场。莱伊博士是肿瘤学、基因组学和肿瘤生物学领域的国际知名领导者，任命包括Siteman癌症和McDonnell基因组研究所副主任华盛顿大学圣路易斯分校(WUSTL)，国家癌症咨询委员会成员，前委员会主席国家研究院基因组研究所科学顾问。同样，格雷格·朗莫尔博士也是一个世界分子肿瘤学、EMT和细胞生物学专家，被任命为分子生物学联席主任 WUSTL癌症环境研究所肿瘤学主任兼整合交流主任。一个特别研究咨询委员会(RAC)将提供额外的指导，包括王挺博士、王挺博士、王军博士、王挺博士、王挺博士等。何塞·泽瓦洛斯和罗布·米特拉博士。K08奖将为我提供一个理想的机会，在我的职业目标。详细的培训计划包括RAC和技术/领导技能的发展对于向独立过渡来说是无价的。研究将在WUSTL进行，这是一个享有盛誉的研究促进合作，重视智力交流，拥有无与伦比的设施的研究所。
