该方案的总体目标是建立一个多尺度乳腺癌研究的建模平台， 特别强调肿瘤起始细胞(TIC)的作用。这个建模平台将主要由 两个密切相关的组成部分：生物实验和数学计算模型。对于 实验部分，我们寻求使用新开发的实验和成像方法来识别， 对TIC进行本地化、提纯和表征。进一步的实验将被设计来发现空间定位。 和运动，乳腺癌TIC基因表达和细胞信号的特异性变化。组合在一起 功能基因组学和数据挖掘策略将使我们能够描述新型生长调节剂的特征。此外， 我们的实验和系统生物学相结合的方法将使我们能够评估对实验的反应 可能以一种以前不可能的方式具体抑制或杀死TIC的治疗方法。对于数学方面的 建模组件，我们将开发生物信息学和生物成像模型来整合和分析数据 从生物实验中产生，并利用从数据分析中获得的信息，生物 了解建立电子计算机模型以模拟TIC行为、癌细胞凋亡、细胞迁移、周期和药物 治疗反应。除了为理解乳房的潜在机制提供一个基本框架 癌症干细胞进化的模型也可以催生假说或实验设计。更重要的是， 这些模型将使人们能够预测研究中的生物状态，并预测自然环境 进程将在各种情况下运行。这两个组件之间的迭代反馈将完善我们的 提出了进一步的平台建议。最终目标是建立一个完整的乳腺癌生物学建模平台 可以足够忠实地模拟体内过程，作为h5TD论文生成和筛选工具，并且在 遥远的未来，作为评估临床程序及其预期结果的工具。

The overall goal ofthis proposal is to build a multi-scale modeling platform for investigation ofthe breast cancer, with special emphasis on the roles ofthe tumor-initiating cells (TIC). This modeling platform will mainly consist of two closely related components: biological experiments and mathematical computational modeling. For the experiment component, we seek to use newly developed experimental and imaging methodologies to identify, localize, purify and characterize TIC. Further experiments will be designed to discover the spatial localization and movement, and specific changes in gene expression and cellular signaling of breast cancer TIC. Combined functional genomics and data mining strategies will allow us to characterize novel growth regulators. Further, our combined experimental and systems biology approach will allow us to evaluate responses to experimental therapeutics that may inhibit or kill TIC specifically in a manner not possible before. For the mathematical modeling component, we will develop bioinformatics and bio-imaging models to integrate and analyze the data generated from biological experiments, and make use ofthe information obtained from data analysis, biological knowledge to build in silico models to model TIC behavior, cancer cell apoptosis, cell migration, cycle and drug treatment response. Besides providing a basic framework for understanding the mechanism underlying breast cancer stem cell evolution, the models can also give birth to hypotheses or experimental design. More important, these models will allow one to predict the biological state under investigation and predict how the natural process will behave in various circumstances. Iterative feedback between these two components will refine our proposed platform further. The ultimate goal is an integrated modeling platform of breast cancer biology that can mimic in vivo processes faithfully enough to serve as a h5TDOthesis-generation and screening tool, and in the distant future, as a tool for evaluating clinical procedures and their expected outcomes.
