Developing Integrated Biological Models from Data for Understanding Diseases

Nirav P Bhatt

Department of Biotechnology, IIT Madras

The functioning of a cell requires multiple processes to act in an integrated manner. It is important to understand mechanisms of these cellular processes in normal and disease states for discovering novel biomarkers and novel therapeutics. The mathematical models describing these processes such as metabolic reactions, signaling and regulatory pathways and their interactions for different contexts (cell types, tissues, diseases) can help to understand these mechanisms in normal and disease states. In this talk, we will present a mathematical framework for developing context-specific genome-scale metabolic models (GMM) integrated with signaling pathways, reactive species pathways, and also different tissues. We will demonstrate that the integration of these pathways can help to understand different diseases such as cancers, metabolic disorders. We will develop integrated models (reactive species pathways with GMMs) for colorectal cancer, basal-like triple negative breast cancer (TNBC), and high grade serous ovarian cancer (HGSOC) using transcriptomics data. We will demonstrate that the proposed integrated biological networks provide insight into the deregulation of different pathways such as fatty acid oxidation and synthesis, glycerophospholipid metabolism, arachidonic acid metabolism, etc. in cancers and mimic cancer phenotypes in-silico.
