1. Host cell responses to viral infection can be monitored by a variety of different high throughput experimental methodologies in order to understand the biological systems involved. The Influenza Research Database 1 (IRD, www.fludb.org) and Virus Pathogen Resource 2 (ViPR, http://www.viprbrc.org), free online database resources supported by the U.S. National Institute of Allergy and Infectious Diseases (NIAID) Bioinformatics Resource Centers (BRC) program, recently developed and implemented a “Host Factor” data management and analysis component that contains results from 55 host factor experiments performed by the NIAID-sponsored Systems Biology for Infectious Diseases Research Programs – Systems Virology (www.systemsvirology.org) and Systems Influenza (www.systemsinfluenza.org) 3.www.fludb.org http://www.viprbrc.orgwww.systemsvirology.orgwww.systemsinfluenza.org Comparative analysis of host response transcriptomic and proteomic enrichment profiles in the Influenza Research Database (IRD) and Virus Pathogen Resource (ViPR) Brian D.

Introduction Data from 55 Experiments Available SARS/MERS Pathway Enrichment Study Design Access Data in IRD and ViPR 35 transcriptomic, 16 proteomic, 4 lipidomic experiments supported 2845 experiment samples 590 host factor biosets 24 different viral (influenza, SARS, MERS) and 2 non-viral agents Summary References Similarity in Host Factor Biosets J=0.27 J=0.23 J=0.35 J=0.51 J=0.21 J=0.32 J=0.24 J=0.08 J=0.41 J=0.02 h i j In transcriptomic experiments using the same virus and hosts model system (a – f), similar host responses were observed, with Jaccard index values (J) ranging from 0.23 – 0.51 Proteomics experiments showed less consistency (g) Little overlap was observed between responses to 1918, seasonal and pandemic H1N1 (h, J=0.08) and proteomics and transcriptomics responses (j, J=0.02) Peak transcriptional responses to SARS and MERS infection show a significant up-regulation of genes involved in intracellular signaling, incl. the RIG-I pathway SARS/MERS appear to affect the subset of RIG-I signaling that induces expression of inflammatory cytokines without affecting type I interferons IRD and ViPR provide access to an expanding amount of “omics” host response data derived from the NIAID-sponsored Systems Biology program and others. Similarity in host responses to viral infections detected from similar experiments suggest that the overall data quality is high. Enrichment analysis of SARS/MERS peak responses suggest that pathogenesis may result from the preferential induction of inflammation without interferon.
