With the advancement of high-throughput biotechnologies, we increasingly accumulate biomedical data about diseases, especially cancer. There is a need for computational models and methods to sift through, integrate, and extract new knowledge from the diverse available data, to improve the mechanistic understanding of diseases and patient care. To uncover molecular mechanisms and drug indications for specific cancer types, we develop an integrative framework able to harness a wide range of diverse molecular and pan-cancer data. We show that our approach outperforms the competing methods and can identify new associations. Furthermore, it captures the underlying biology predictive of drug response. Through the joint integration of data sources, our framework can also uncover links between cancer types and molecular entities for which no prior knowledge is available. Our new framework is flexible and can be easily reformulated to study any biomedical problem.
随着高通量生物技术的进步,我们越来越多地积累了有关疾病,尤其是癌症的生物医学数据。需要计算模型和方法来筛选、整合并从各种可用数据中提取新知识,以增进对疾病的机理理解并改善患者护理。为了揭示特定癌症类型的分子机制和药物适应症,我们开发了一个能够利用广泛多样的分子和泛癌数据的综合框架。我们表明,我们的方法优于竞争方法,并且可以识别新的关联。此外,它捕捉了预测药物反应的潜在生物学特性。通过联合整合数据源,我们的框架还可以揭示癌症类型与尚无先验知识的分子实体之间的联系。我们的新框架很灵活,可以轻松重新制定以研究任何生物医学问题。
