Dr. Nathan Price at the Vancouver Bioinformatics Users Group 2012: “Integrated modeling of metabolic and regulatory networks”

In this presentation at the the Vancouver Bioinformatics Users Group from 2012, Nathan Price  discusses approaches for the creation of quantitative systems models that can harness the power of genomics, by linking genotype to phenotype. The talk focuses particularly on automated methods for integrating metabolic and regulatory networks, such as Probabilistic Regulation of Metabolism (PROM) (Chandrasekaran and Price, PNAS, 2010). PROM is notable in that it represents the successful integration of a top-down reconstructed, statistically inferred regulatory network with a bottom-up reconstructed, biochemically detailed metabolic network, bridging two important classes of systems biology models that are rarely combined quantitatively. A strategy to curate the inference of regulatory interactions from high throughput data using metabolic networks is discussed—providing multiple layers of biological context to the problem of regulation. Finally, an approach for building tissue and cell type specific metabolic models is also presented, applied to 131 different cell types and tissues in the human body.

The Vancouver Bioinformatics Users Group (VanBUG) is an association of Bioinformatics enthusiast in the B.C. Lower Mainland, Canada.

    Bile Acids Provide More Evidence of the Gut Microbiome’s Effect on Alzheimer’s Disease

    ISB researchers and their collaborators are looking beyond the one-drug, one-solution approach that has thus far failed in Alzheimer’s disease research. Instead, they are focusing on other promising research avenues, such as the possible role of the gut microbiome in dementia.

    Variations in the Microbiome Associated with Health, Disease

    ISB researchers examined the associations between the gut microbiomes of about 3,400 people and roughly 150 host characteristics. The team looked at diet, medication use, clinical blood markers, and other lifestyle and clinical factors, and found evidence that variations of the gut microbiome are associated with health and disease.

    ISB Researchers Identify Signals of Metastatic Cancer Years Prior to Diagnosis

    By analyzing blood plasma samples taken at several time points, ISB researchers have identified specific proteins that persistently presented as outliers and signaled metastatic cancer well before patients were diagnosed. The findings were published in the journal Scientific Reports.
