Morning Short Course

Systems Biology: A Molecular Nutrition Perspective 


Monday, February 10, 2014 | 8:30 - 11:30 am | Moscone North Convention Center | San Fransisco, CA 


ABOUT THIS SHORT COURSE:

The health of people is highly influenced by genome-environment interactions and the biggest interaction is through diet. Therefore, genetic variability and diet variability concur to create highly specific environments in which diseases develop and drugs acts. It is more and more obvious that diet is a key variable to prevent and cure multifactorial diseases. In this scenario, is becoming of fundamental importance to understand how different population interact with food (different geo-political areas have very different habit) and how genome reacts to food. The main door of food to our molecular environment is through intestine, where we host more than 1 kg of bacteria, the so called microbiome. Understanding how the individual variability in microbiome influence micronutrient absorption and their consequent interaction with our molecular processes is another fundamental step in including the effect of diet in health maintenance. Finally, the main metabolic processes affected by nutrients are also involved in many diseases and their understanding in relation to diet can open new perspective in the treatment of these diseases. Unfortunately, considering diet as a key player in understanding diseases the complexity of the systems under investigation grows even further with respect to the usual systems biology problems. Therefore innovative computational systems approaches are absolutely essential to manage the complexity. The course will cover the intervention studies to understand population variability with respect to diet, the microbiome studies to deal with nutrient absorption, the molecular mechanism of metabolic processes related to nutrients and the computational techniques that could be used in these contexts.

Talk Title to be Announced

Patrick J. Stover, Ph.D., Professor and Director, Division of Nutritional Sciences, Cornell University

Understanding the “variability in individual responses” to dietary exposures and its relationship to human health and performance continues to be one of the major challenges in the nutritional sciences, including the establishment of population-based dietary recommendations and public health guidelines. Understanding the interactions among nutrients and other bioactive food components, human genetic variation and epigenetic variation is fundamental to elucidating inter- and intra-population differences in responses to diets. The design of physiologically relevant model systems and experimental approaches for studying the connections between one-carbon metabolism and cancer in heterogeneous human populations will be addressed. 

 

Experimental Designs for Systems Nutrition Research

Jim Kaput, Ph.D., Head, Clinical Translation Unit; Delta Vitamin Study Team1, Systems Nutrition and Health Unit, Nestle Institute of Health Sciences

Although systems biology concepts and technologies are beginning to alter experimental design and analyses, research conducted in the 21st century continues to focus on physiological effects caused by providing an individual nutrient to groups of individuals with analysis of a small number of biomarkers. Similarly, geneticists focus on associating an individual polymorphism in a gene to a complex biological process, which typically is a disease. Genome wide association studies (GWAS) rely upon mathematical tools and criteria that analyze the association of multiple but independently-tested SNPs with some complex phenotype.

We are developing strategies for analyses of individual data (n-of-1) for identifying metabolic groups in children ages 6 to 14 in the Delta Obesity Vitamin Study. Our approach analyzed for patterns of plasma and erythrocyte metabolites. The data from n-of-1 studies were aggregated and used to analyze population level results: differences or similarities between sex, by age, by geographic location, or other dichotomous variables. A global protein – protein interaction network was analyzed by topological partitioning with enrichment analysis that grouped functionally related genes. Three modules within this global network contained SNPs that differed statistically between groups defined by patterns of metabolite levels. Two of these modules were involved in digestion and absorption functions and immune functions. Plasma proteins involved in immune functions were also correlated with these patterns of metabolites that better defined the physiological status of the study participants. This systems approach may be a model for analysis of other complex phenotypes.

Computational Approaches for Systems Nutrition and Network Analysis

Professor Corrado Priami, Ph.D., Computer Science, The Microsoft Research - University of Trento Centre for Computational and Systems Biology (COSBI)

Computational approaches that are needed for systems nutrition can be composed in pipelines that start from data collection (including omics data, clinical markers, diet and life style) passing through data analysis and mining till simulation and generation of biological hypothesis to better design new intervention studies or biological experiments. We will present one of such pipelines centered around network analysis and pruning to identify the relevant modules for the phenotype under investigation. Once these modules are identified in a data-driven way, they are functionally annotated and possibly dynamically simulated to see how they behave over time. Finally, the results of these in silico experiments are interpreted for the generation of new hypotheses.

Patrick J. Stover, Ph.D., Professor and Director, Division of Nutritional Sciences, Cornell University

PatrickStoverPatrick J. Stover, Ph.D. is Professor and Director of the Division of Nutritional Sciences at Cornell University. He graduated from Saint Joseph’s University with a BS degree in Chemistry and was awarded the Molloy Chemistry Award at graduation. He received a PhD degree in Biochemistry and Molecular Biophysics from the Medical College of Virginia and performed his postdoctoral studies in Nutritional Sciences at the University of California at Berkeley. The Stover research group investigates the chemical, biochemical, genetic and epigenetic mechanisms that underlie the relationships between one-carbon metabolism and human pathologies including neural tube defects, cardiovascular disease and cancer. Specific interests include the regulation of folate-mediated one-carbon metabolism and genome expression and stability, the molecular basis of the fetal origins hypothesis, development of mouse models to elucidate mechanisms of folate-related pathologies, and translational control of gene expression. Our current focus is on the role of nuclear one-carbon metabolism in de novo thymidylate synthesis in maintaining genome integrity, and its regulation by SUMOylation and UV radiation. We have developed mouse models of altered one-carbon metabolism by gentically manipulating the expression of folate-associated genes to determine the effects of altered one-carbon supply on cellular methylation potential, nucleotide biosynthesis and colon cancer susceptibility. An overarching goal of these studies is to differentiate the contributions of folate-dependent de novo nucleotide biosynthesis and folate-mediated cellular methylation in folate-associated pathologies. Patrick Stover also teaches two classes for graduate students: NS7040, Grant Writing and NS6200 Translational Research and Evidence-based Policy and Practice in Nutrition.
