项目摘要
DESCRIPTION (provided by applicant): The goal of this work is to create, validate, and apply an in silico model and tool to predict metabolites that are differentially accumulated in cancer. I is known that metabolites can broadly impact cellular behavior and growth outside of their roles as biosynthetic intermediates, and metabolism is being increasingly recognized as a potential target for cancer therapeutics. We believe that changes in concentration of some metabolites in cancer cells may have an active role in the progression of the disease rather than being just a side effect or consequence of other changes, such that the ability to predict these changes could result in the development of entirely new avenues of metabolism-focused cancer treatment. We have begun to develop an in silico model and tool, named CoMet, to make such predictions. In preliminary work using lymphoblasts, CoMet has successfully identified antiproliferative metabolites, though the accuracy of its predictions of metabolite levels, and its
applicability to other types of cancer, is uncertain. To this end, the first aim of this proposal i to improve CoMet by integrating detailed biological data and using experimental validation results to refine its predictions. To perform our experimental validations, we will use a cutting-edge analytical technique (two-dimensional gas chromatography coupled to mass spectrometry, or GCxGC-MS) to measure the levels of metabolites in cancerous and normal cells and compare these results to predictions made by CoMet. Our second aim is to test the validity of CoMet's predictions of down-regulated and antiproliferative metabolites in multiple types of cancer, and to use these results to further refine CoMet's methodology. Our final aim is to measure the metabolic impact of using metabolites as antiproliferatives, since we suspect that they are having a substantial impact on cellular metabolism. This will allow us to generate hypotheses on their mechanisms of action. This work is a significant step towards gaining a predictive understanding of the metabolic differences between normal and cancerous cells, and of the regulatory roles metabolites play in cancer proliferation and progression. Predicting and understanding these changes would allow for the rational development of drugs that target cancer metabolism, and for advancement of the idea of metabolites that themselves serve as anticancer agents. By attacking such a fundamental aspect of cancer, this work could have a significant and broad long-term impact on cancer mortality and the quality of life of cancer patients.
描述(由申请人提供):这项工作的目标是创建、验证和应用计算机模拟模型和工具,以预测在癌症中差异积累的代谢物。众所周知,代谢物可以广泛地影响细胞行为和生长,而不是作为生物合成中间体,代谢正越来越多地被认为是癌症治疗的潜在靶点。我们认为,癌细胞中某些代谢物浓度的变化可能在疾病的进展中起着积极的作用,而不仅仅是其他变化的副作用或后果,因此预测这些变化的能力可能会导致以代谢为重点的癌症治疗的全新途径的发展。我们已经开始开发一种名为CoMet的计算机模型和工具来进行此类预测。在使用淋巴母细胞的初步工作中,CoMet已经成功地鉴定了抗增殖代谢物,尽管其预测代谢物水平的准确性,
是否适用于其他类型的癌症尚不确定。为此,本提案的第一个目标是通过整合详细的生物数据并使用实验验证结果来改进CoMet的预测。为了进行我们的实验验证,我们将使用尖端的分析技术(二维气相色谱-质谱联用,或GCxGC-MS)来测量癌细胞和正常细胞中代谢物的水平,并将这些结果与CoMet的预测进行比较。我们的第二个目标是测试CoMet对多种类型癌症中下调和抗增殖代谢物预测的有效性,并利用这些结果进一步完善CoMet的方法。我们的最终目的是测量使用代谢物作为抗增殖剂的代谢影响,因为我们怀疑它们对细胞代谢有实质性影响。这将使我们能够产生关于其作用机制的假设。这项工作是朝着预测了解正常细胞和癌细胞之间的代谢差异以及代谢物在癌症增殖和进展中发挥的调节作用迈出的重要一步。预测和理解这些变化将允许合理开发针对癌症代谢的药物,并推进代谢物本身作为抗癌剂的想法。通过攻击癌症的这样一个基本方面,这项工作可能对癌症死亡率和癌症患者的生活质量产生重大而广泛的长期影响。
