[2017-12] Xiaojing’s paper Detection of proteome diversity resulted from alternative splicing is limited by trypsin cleavage specificity. has been published in Molecular & Cellular Proteomics. Congratulations, Xiao Jing! Alternative splicing dramatically increases transcriptome complexity but its contribution to proteome diversity remains controversial. Exon-exon junction spanning peptides provide direct evidence for the translation of specific splice isoforms and are critical for delineating protein isoform complexity. In this paper, we studied the proteomic coverage of exon-exon junctions in three publicly available proteomics data sets and found that trypsin preferentially cleaves exon-exon junctions and thus hinders the detection of junction-spanning peptides. This phenomenon was explained by evolutionarily conserved preferential nucleotide usage at exon boundaries according to nucleotide sequence analysis of five eukaryotic genomes. Our in silico and experimental analyses showed that complementary digestion schemes are essential to study the translation of alternative mRNA splicing to proteome diversity.
[2017-11] Dr. Eric Jaehnig joined the group as a Research Associate. Eric received his Ph.D. degree in Biology from the University of California, San Francisco, followed by postdoctoral training in systems biology at the Ludwig Institute for Cancer Research. To enhance his quantitative skills, Eric recently completed a Master’s degree in Bioengineering from the Rice University. Welcome, Eric!
[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).
