Understanding the physiological state of normal and cancerous tumor cells has limited our understanding of how cells grow and respond to their environment. In this collaborative project the PIs will construct synthetic living biosensors that can be mixed with other cells to provide readily detectable and measurable information on the cells physiological state, including the response of tumor cells to therapeutic agents. This will improve our ability to model normal and cancer cell biology, contributing to our understanding of how potential therapeutic agents affect cells. This approach will permit detecting multiple physiological states simultaneously, in a high-throughput manner. In terms of broader impacts this project will enhance ongoing outreach activities to engage undergraduate students, K-12 students, and the public in STEM through several ongoing programs at each institution as well as by new activities to enhance interactions between institutions.This project will develop synthetic biology tools and experimental approaches that will enable the development of more sophisticated models of normal and cancer cell physiological properties, including information about the immediate environment and response to therapeutic agents. The first step will be to develop genetically encoded live cell sensors that will report information about multiple cell physiological states, including treatment biomarkers. The second step will be to develop real-time reporting by the sensors via loading of barcoded synthetic RNA molecules distinct for each biomarker to be detected by next-generation sequencing. The goal of this EAGER is to develop and validate each of the key technological foundations required to be successful. In terms of broader impacts, this project will contribute to the training of the next generation work-force in synthetic, cellular, and cancer biology. This project will also include cross-institutional virtual meetings to enhance student networking by the iGEM teams at each institution.

了解正常和癌性肿瘤细胞的生理状态限制了我们对细胞如何生长和对其环境的反应的理解。 在这个合作项目中，PI将构建合成的活生物传感器，可以与其他细胞混合，以提供有关细胞生理状态的易于检测和测量的信息，包括肿瘤细胞对治疗药物的反应。 这将提高我们模拟正常和癌细胞生物学的能力，有助于我们了解潜在的治疗药物如何影响细胞。 该方法将允许以高通量方式同时检测多个生理状态。 在更广泛的影响方面，该项目将加强正在进行的外联活动，以吸引本科生，K-12学生，该项目将开发合成生物学工具和实验方法，从而能够开发出更复杂的正常和癌细胞生理模型。属性，包括关于直接环境和对治疗剂的反应的信息。 第一步将是开发基因编码的活细胞传感器，该传感器将报告有关多种细胞生理状态的信息，包括治疗生物标志物。 第二步将是通过加载条形码合成RNA分子来开发传感器的实时报告，这些条形码合成RNA分子对于下一代测序检测的每种生物标志物都是不同的。 EAGER的目标是开发和验证成功所需的每个关键技术基础。就更广泛的影响而言，该项目将有助于培养合成、细胞和癌症生物学方面的下一代工作人员。该项目还将包括跨机构的虚拟会议，以加强每个机构的iGEM团队的学生网络。
