[2017-11] Suhas’ paper LinkedOmics: analyzing multi-omics data within and across 32 cancer types has been published in Nucleic Acids Research. LinkedOmics is a new and unique resource for disseminating and analyzing The Cancer Genome Atlas (TCGA) data. It is also the first multi-omics database that integrates mass spectrometry (MS)-based global proteomics data generated by the Clinical Proteomic Tumor Analysis Consortium (CPTAC) on selected TCGA tumor samples. LinkedOmics has three analysis modules. The LinkFinder module allows flexible exploration of associations between a molecular or clinical attribute of interest and all other attributes, providing the opportunity to analyze and visualize associations between billions of attribute pairs for each cancer cohort. The LinkCompare module enables easy comparison of the associations identified by LinkFinder, which is particularly useful in multi-omics and pan-cancer analyses. The LinkInterpreter module transforms identified associations into biological understanding through pathway and network analysis. In this paper, we used five case studies to demonstrate that LinkedOmics provides a unique platform for biologists and clinicians to access, analyze and compare cancer multi-omics data within and across tumor types. Although the current version of LinkedOmics includes only TCGA and CPTAC data, it can be easily extended to support other cohort-based multi-omics studies.

[2017-05] Jing’s paper WebGestalt 2017: a more comprehensive, powerful, flexible and interactive gene set enrichment analysis toolkit has been published in Nucleic Acids Research. The WebGestalt 2017 knowledge base supports 12 organisms, 324 gene identifiers from various databases and technology platforms, and 150,937 functional categories from public databases and computational analyses. Importantly, omics data with gene identifiers not supported by WebGestalt and functional categories not included in the WebGestalt database can also be uploaded for enrichment analysis. The analysis module supports Over-Representation Analysis, Gene Set Enrichment Analysis, and Network Topology-based Analysis. The input interface is simplified, the output interface allows interactive and efficient exploration, and the complete set of results can be easily downloaded. The new GOView tool makes it easy to compare multiple sets of GO enrichment results in the context of the GO directed acyclic graph (DAG).

[2013-05] Congratulations to Jing on the new Nucleid Acids Research paper WEB-based GEne SeT AnaLysis Toolkit (WebGestalt): update 2013. This is an update from a previous publication on WebGestalt in the same journal in 2005. For the last 7 years, WebGestalt data holdings have grown substantially to satisfy the requirements of users from different research areas. The current version of WebGestalt supports 8 organisms and 201 gene identifiers from various databases and different technology platforms. Meanwhile, by integrating functional categories derived from centrally and publicly curated databases as well as computational analyses, WebGestalt has significantly increased the coverage of functional categories in various biological contexts including Gene Ontology, pathway, network module, gene–phenotype association, gene–disease association, gene–drug association and chromosomal location, leading to a total of 78,612 functional categories. Finally, new interactive features, such as pathway map, hierarchical network visualization and phenotype ontology visualization have been added to WebGestalt to help users better understand the enrichment results. WebGestalt can be freely accessed through http://www.webgestalt.org or http://bioinfo.vanderbilt.edu/webgestalt/ .

Moreover, sequence features known to drive site efficacy in mRNA decay were generally not applicable to translational repression. Congratulations, Qi!
