DESCRIPTION (provided by applicant): Many complex human diseases (e.g. cancer, diabetes, schizophrenia etc.) have correspondingly complex, polygenic genotypes that initiate and sustain disease progression. Despite significant progress over the past few decades identifying genes critical to mediating phenotype, our understanding of the functional basis of molecular phenotype for complex diseases is insufficient. Signaling pathways that consist of a few proteins interacting in a serial fashion oversimplify and provide inadequate models for the behavior mediated by multiple interacting gene products. Partly revealed by rigorous studies of increasingly well-annotated protein-protein interaction (PPI) networks, it has become clear that many of the proteins in these canonical signaling pathways engage in "crosstalk" with, and are modulated by, an ontologically diverse set of additional proteins, where this crosstalk is frequently mediated in a tissue and/or disease specific manner. We propose to develop and deliver an integrated suite of software tools to the academic and commercial research community to fulfill the unmet demand for quantitative PPI network analysis that can drive practical translational research and validation. The tool DiseaseNet Finder will search for and score candidate disease sub- networks within global PPI networks. It will permit integration of multiple high- dimensional -omic types (GWAS, SNP, CNV, proteomic, miRNA etc.) with PPI networks and include classification tools. Novel aspects of the software include: combinatorial scoring, multi data type integration, node and edge prediction tools, with end-point classification and quantitative scoring seamlessly implemented through graphical user interfaces. PUBLIC HEALTH RELEVANCE: Complex diseases include the contributions of many genes interacting with the environment. Enhanced computational research tools to discover biomarkers and understand complex disease mechanisms are needed to integrate the various types of genomic and proteomics data that are accumulating. This will permit a more rapid development of personalized medicine.

描述（由申请人提供）：许多复杂的人类疾病（如癌症、糖尿病、精神分裂症等）具有相应的复杂的多基因基因型，这些基因型启动并维持疾病进展。尽管在过去的几十年里，鉴定对介导表型至关重要的基因取得了重大进展，但我们对复杂疾病分子表型的功能基础的理解还不够。由几个蛋白以一系列方式相互作用组成的信号通路过于简化，并且为多个相互作用的基因产物介导的行为提供了不充分的模型。对越来越多的蛋白-蛋白相互作用（PPI）网络的严密研究部分揭示了这些典型信号通路中的许多蛋白质与一组本体论上多样化的其他蛋白质进行“串扰”，并被其调节，其中这种串扰经常以组织和/或疾病特定的方式介导。我们建议为学术和商业研究界开发并提供一套集成的软件工具，以满足对定量PPI网络分析的未满足需求，从而推动实际的转化研究和验证。疾病网查找工具将在全球PPI网络中搜索并评分候选疾病子网络。它将允许将多个高维组学类型（GWAS， SNP， CNV，蛋白质组学，miRNA等）与PPI网络集成，并包括分类工具。该软件的新颖方面包括：组合评分，多数据类型集成，节点和边缘预测工具，通过图形用户界面无缝实现端点分类和定量评分。
