项目摘要

DESCRIPTION (provided by applicant): The effectiveness of targeted anti-cancer therapeutics is frequently reduced by the acquisition of drug- resistance. A comprehensive understanding of the mutations compatible with oncogene function should define the mutations available to direct drug-resistance and provide a guide for the rational development of improved inhibitors with reduced probability of resistance. Traditional approaches to analyze the functional effects of mutations rely on randomly generated mutants and typically can only identify a handful of mutations with a strongly selected phenotype. We propose an approach to systematically analyze the functional effects of all possible single-nucleotide substitutions for entire oncogenes both in the presence and absence of inhibitors. Our approach will systematically define the positive or negative impact of each mutation on cell growth. Only mutations that are compatible with oncogene function should be available to drug resistance evolution. Therefore, identifying the set of functional mutations provides a powerful structural guide that can be incorporated in the early stages of future drug design efforts.

描述(由申请人提供)：靶向抗癌治疗的有效性经常因获得抗药性而降低。对与癌基因功能相容的突变的全面理解应该确定可用于直接耐药的突变，并为合理开发降低耐药概率的改良抑制剂提供指导。分析功能的传统方法突变的影响依赖于随机产生的突变，通常只能识别少数具有强烈选择表型的突变。我们提出了一种方法来系统地分析所有可能的单核苷酸替换整个癌基因在存在和不存在抑制剂的情况下的功能效应。我们的方法将系统地定义每个突变对细胞生长的积极或消极影响。只有与癌基因功能相容的突变才能用于耐药进化。因此，识别一组功能突变提供了一个强大的结构指南，可以被纳入未来药物设计工作的早期阶段。
