DESCRIPTION (provided by applicant): Modern genome-scale experimental techniques enable for the first time in biological research the comprehensive monitoring of the entire molecular regulatory events leading to disease. Their integrative analyses hold the promise of generating specific, experimentally testable hypotheses, paving the way for a systems-level molecular view of complex disease. However, systems-level modeling of metazoan biology must address the challenges of: 1. biological complexity, including individual cell lineages and tissue types, 2. the increasingly large scale of data in higher organisms, and 3. the diversity of biomolecules and interaction mechanisms in the cell. The long-term goal of this research is to address these challenges through the development of bioinformatics frameworks for the study of gene function and regulation in complex biological systems thereby contributing to a greater understanding of human disease. In the initial funding period, we have developed accurate methods for integrating and visualizing diverse functional genomics data in S. cerevisiae and implemented them in interactive web-based systems for the biology community. Our methods have led to experimental discoveries of novel biology, are widely used by the yeast community, and are integrated with the SGD model organism database. We now propose to leverage our previous work to develop novel data integration and analysis methods and implement them in a public system for human data. In the proposed research period, we will create algorithms appropriate for integrating metazoan data in a tissue- and cell-lineage specific manner in health and disease. We will also develop novel hierarchical methods for predicting specific molecular interaction mechanisms and will extend our methods for integrating additional biomolecules. These methods will direct experiments focused on the glomerular kidney filter, a critical and complex component of the human vascular system whose dysfunction directly contributes to microvascular disease. Prediction of these cell-lineage specific functional networks will advance the understanding of the glomerulus function and its role in microvascular disease, leading to better clinical predictors, diagnoses, and treatments. From a technical perspective, application to glomerular biology will enable iterative improvement of the proposed methods based on experimental feedback. The end product of this research will be a general, robust, interactive, and automatically updated system for human data integration and analysis that will be freely available to the biomedical community. We will leverage parallel processing technologies (inspired by Google- type cloud computing solutions) to ensure interactive-analysis speed on the system. This system will allow biomedical researchers to synthesize, analyze, and visualize diverse data in human biology, enabling accurate predictions of biological networks and understanding their cell-lineage specificity and role in disease. Such integrative analyses will provide experimentally testable hypotheses, leading to a deeper understanding of complex disorders and paving the way to molecular-defined tissue targeted therapies and drug development.
