Hands-on Cytoscape Clinic.

In this workshop, organized by SDCSB and FluOMICS, the Cytoscape development team used a completely new format to provide a hands-on tutorial in an intimate classroom setting. Attendees at the yearly spring workshop had previously requested a non-lecture format where individuals can pose problems that will be directly addressed by Cytoscape tutors and developers. The fall workshop was held as a clinic, where Cytoscape users signed up for 15 minute slots where he/she presented a problem (preferentially with actual data), and Cytoscape tutors, developers, and users were able to address it directly on the spot. Hosted by Barry Demchak, UCSD.

We would like to announce that a new pilot project has been awarded through the FluOMICS program to:
Benjamin tenOever and Kris White, Icahn School of Medicine at Mount Sinai. New York, NY.

The goal of this project is to develop a novel tool for the study of mRNA degradation rates in the presence of an active IAV infection. We will then apply this new technique to obtain the first comprehensive view of transcriptome stability dynamics during infection. Through bioinformatic analysis of this new and existing data from the U19 consortium we will be able to determine cis-acting mRNA sequences that are targeted and the overall role degradation plays in modulation of the host environment. Specific Aims are (1) to develop novel tools to study intrinsic host mRNA stability throughout the IAV life cycle in vitro, and (2) to determine mRNA stability at a global level in IAV-infected cells.

We have just launched Metascape, a new gene annotation and analysis tool. The aim of Metascape is to develop a set of reliable, productive and intuitive tools that help biomedical research community to analysis gene/protein lists and make better data-driven decisions. Although a plethora of databases and tools exist for gene annotation and gene list enrichment analysis, it remains challenging for researchers, especially those who are not trained to programming, to gather some very basic annotation data for their list of genes.

The Metascape web site and tools enable users to apply popular bioinformatics analyses to one or multiple gene/protein lists in order to make effective data-driven gene prioritization decisions. Just with a few mouse clicks, we can start from lists of gene/protein identifiers, extract rich annotations and identify statistically enriched pathways. http://www.metascape.org/

We would like to announce that a new pilot project has been awarded through the FluOMICS program:

Jeffrey R. Johnson, The J. David Gladstone Institutes. San Francisco, CA

The mass spectrometric analysis of complex protein mixtures is often hindered by a high degree of complexity. Abundant proteins dominate the mass spectrometer’s duty cycle producing spectra that are highly redundant and obscure the detection of less abundant proteins. This proposal aims to develop a novel technology to simplify complex protein mixtures by isolating partially digested N-terminal protein fragments. The successful implementation of such a method will increase the coverage of the proteome that may be captured and reduce the instrument time required to obtain a comprehensive snapshot of the proteome. Eliminating fractionation methods for proteome analysis will also allow for label-free quantification methods to be applied to characterize protein dynamics with high sensitivity and in biologically relevant systems with ease.

We would like to announce that two pilot projects have been awarded through the FluOMICS program:

Global assessment of virus-induced host protein mislocalization events

Sumit Chanda, Sanford Burnham Instititue. La Jolla, CA

The goal of this project is to develop and execute a high-throughput screen to assess alterations in host protein subcellular localization after influenza infection. To address the hypothesis that viruses retarget host protein distribution to evade immune detection, we propose to establish and optimize a high-throughput screening platform to interrogate subcellular (trans)localization events. The screen to be performed will evaluate the impact of influenza infection on the localization of ~500 host proteins that encode a variety of genes related to pattern recognition, interferon signaling and interferon-dependent target genes. To facilitate the highthroughput approach, epitope-tagged cDNAs will be transduced into cells, and after viral challenge, cells will be fixed, stained, and imaged utilizing high-content microscopy. Refined automated imaging analysis algorithms will enable us to computationally identify differential localization events. Validation and kinetic analysis of trafficking events targeted by influenza. To assess the biological relevance of candidate genes identified in SA1, we will assess the translocation events of endogenous proteins (when antibodies are available), as well as perform kinetic analyses of translocation with RFP-tagged proteins (3-5 genes).

Influenza virus-induced changes in host 3D genome architecture

The goal of this highly innovative Fluomics pilot proposal is to characterize changes in the three dimensional configuration of the host genome in response to influenza virus infection to establish how long-range chromatin interactions contribute to regulation of the virus-host transcriptional network. We hypothesize that these events contribute to viral replication and/or disease pathogenicity. For these studies we will employ Hi-C, a powerful technique that couples spatial proximity DNA ligation with massively parallel sequencing technology, and that is capable of resolving promoter-enhancer regulatory domains as well as large scale rearrangement of chromosomes.
