项目摘要

PROJECT SUMMARY This diversity supplement to the funded “Mechanisms and Targeted Therapy of NRF2high Esophageal Squamous Cell Carcinoma” (R01CA244236) will expand the scope of the funded grant to study how levels of reactive oxygen species (ROS) governs global kinase activity in ESCC. In the parent grant, we are characterizing the molecular and phenotypic consequences of NRF2 hyperactivation in ESCC, determining the mechanisms of action and efficacy of NRF2 small molecule inhibitors, and identifying NRF2-responsive kinases and their functions in NRF2-driven ESCC biology. As a complement and extension of this work, the proposed diversity supplement fills a void not studied in the parent project—the role of reactive oxygen species in the regulation of kinase activity and kinase signal transduction in ESCC. This supplement will support Dr. Emily Zarbock’s career development, giving her new scientific skills in cancer cell biology, molecular biology and signal transduction. Dr. Zarbock is an expert in analytical chemistry and mass spectrometry, and new expertise in cancer cell biology will enhance her academic career as she builds her independent research program. In the proposed project, Dr. Zarbock aims to: 1) quantify ROS levels and dynamics in ESCC human cell lines grown in 2D and in 3D as spheroids 2) identify Redox-sensitive kinases in ESCC and 3) determine the role of select redox-sensitive kinases on ESCC signal transduction and cell biology. Dr. Zarbock will work to connect reactive oxygen species to kinases, which while being increasingly appreciated, has not been comprehensively studied or examined in ESCC model systems.

项目摘要这种多样性补充了资助的“NRF 2 high食管癌的机制和靶向治疗”，鳞状细胞癌”（R 01 CA 244236）将扩大资助的范围，以研究如何水平活性氧（ROS）的释放控制着ESCC中的整体激酶活性。在父母补助金中，我们表征ESCC中NRF 2过度活化的分子和表型后果， NRF 2小分子抑制剂的作用机制和功效，并鉴定NRF 2响应性抑制剂。激酶及其在NRF 2驱动的ESCC生物学中的功能。作为这项工作的补充和延伸，拟议的多样性补充填补了一个空白，没有研究在母项目-活性氧的作用在食管鳞癌激酶活性调节和激酶信号转导中的作用。该补充将支持艾米丽扎博克博士的职业发展，给她在癌细胞生物学新的科学技能，分子生物学和信号转导。扎伯克博士是分析化学和质谱方面的专家光谱，和新的专业知识，在癌细胞生物学将提高她的学术生涯，因为她建立了她的独立研究计划。在拟议的项目中，Zarbock博士的目标是：1）量化ROS水平，在2D和3D中作为球状体生长的ESCC人细胞系的动力学2）鉴定氧化还原敏感性激酶在ESCC中的作用; 3）确定选择的氧化还原敏感性激酶在ESCC信号转导中的作用和细胞生物学。Zarbock博士将致力于将活性氧与激酶联系起来，越来越多的人认识到，尚未在ESCC模型系统中进行全面的研究或检查。
