The Omics & BioInformatics Core (OBIC) provides comprehensive and innovative support for study design, sample preparation, analysis, interpretation, and integration of a broad range of omics studies.
Expertise in the design and implementation of a broad range of studies, including expertise on:
- study design
- technology platforms
- sample preparation
- other protocols
Sequencing and Bioinformatics services for genomics and epigenomics studies, including:
- microRNA expression
- HumanMethylation450 BeadChip
- reduced representation (RRBS) or whole-genome (WGBS) bisulfite sequencing
- MeDIP-seq, MethylCap-seq, hmeDIP-seq, etc.
- Enrichment testing (pathway analysis), and more
Assistance in publication and grant preparation (including P30 pilot proposals), data sharing, presentations (e.g., data visualization).

Provide genomic analysis resources for all Center-related projects. Researchers will have access to full services for epigenomics experiments; individual labs may submit cells for DNA/RNA extraction or ChIP-DNA for ChIP-Seq. The core will perform sample library preparation for the main DNA methylation platforms and sequencing applications, RNA-seq, or ChIP-seq. Prepared samples will be sent directly to the UM DNA Sequencing core, and generated data will be sent directly for bioinformatics service. In addition to the Epigenomics-related services described above, Center researchers can directly request access to technologies such as whole-genome sequencing, small RNA sequencing, microarrays, etc.
OBIC organizes workshops for environmental scientists and the broader biomedical community to learn more about current omics and bioinformatics approaches. Our most recent workshop was a great success and offered ample time for networking among environmental health scientists. For example:
- Training classes and/or one-on-one consultations are available (see below, for resource details). Suggestions for future offerings are welcome. For more information, contact Marci Brandenburg, Maureen Sartor, or Rich McEachin. Upcoming workshops offered through the Taubman Health Sciences Library can be found here: http://www.lib.umich.edu/taubman-health-sciences-library/workshops-and-instruction
Selected Tools & Resources
- Cytoscape: Cytoscape is an open source bioinformatics platform for visualizing molecular interaction networks and biological pathways and integrating these networks with annotations, gene expression profiles and other state data. The Cytoscape core distribution provides a basic set of features for data integration and visualization. Additional features are available as plugins. (http://www.cytoscape.org)
- MetScape: The MetScape plugin for Cytoscape provides a bioinformatics framework for the visualization and interpretation of metabolomic and gene expression profiling data, in the context of human metabolism. It allows users to build and analyze networks of genes and compounds, identify enriched pathways from expression profiling data, and visualize changes in metabolite data. (http://metscape.ncibi.org)
- GeneGo: Need a tool to make biological sense of high-throughput data? GeneGo provides a commercial solution for using gene/protein/miRNA/RNA/drug/metabolite lists and “omics” data to generate and prioritize hypotheses. MetaCore is an integrated knowledge database and software suite for pathway analysis of experimental data and gene lists. The scope of data types includes microarray and sequence-based gene expression, SNPs and CGH arrays, proteomics, metabolomics, Co-IP pull-out and other custom interactions. ToxHunter is a systems toxicology knowledgebase and data analysis package, designed for the assessment of safety liabilities of drugs, environmental contaminants and other xenobiotics at all stages of discovery and development. CCMB has a license for use of GeneGo. (www.genego.com)
- ConceptGen, LRpath and ChIP-Enrich: ConceptGen is a gene set enrichment and gene set relation mapping tool that can help you identify, explore, and visualize relationships and significant overlaps among sets of genes (concepts). ConceptGen is built on a repository of gene and protein annotation data drawn from diverse sources. (http://conceptgen.ncibi.org). LRpath is an alternative, statistically powerful gene set enrichment testing method that can aid in interpreting high-throughput results, such as from gene expression or DNA methylation experiments (http://lrpath.ncibi.org). ChIP-Enrich is a website and Bioconductor package for functional enrichment testing of ChIP-seq data (http://chip-enrich.med.umich.edu). It’s sister program, Broad-Enrich, is more useful for sets of broad genomic regions, such as those identified by many histone modifications (http://broad-enrich.med.umich.edu)
- Gene2MeSH and Metab2MeSH: Gene2MeSH and Metab2MeSH use a statistical approach to reliably and automatically annotate genes or small compounds, respectively, with the concepts defined in Medical Subject Headings (MeSH). MeSH is the National Library of Medicine’s controlled vocabulary for biology and medicine, and includes diseases, phenotypes, environmental exposures and other chemicals, plus much more. (http://gene2mesh.ncibi.org and http://metab2mesh.ncibi.org)
- Epigenomics web portal (Bisphenol A) – The Epigenomics portal is an integrative, web-based computational platform for the analysis and mining of genomics data, developed at the University of Cincinnati by a BIC external advisor. It is a useful resource especially for those studying BPA. (http://eh3.uc.edu/GenomicsPortals)
- Comparative Toxicogenomic Database (CTD): CTD advances understanding of the effects of environmental chemicals on human health. CTD includes curated data describing cross-species chemical–gene/protein interactions and chemical– and gene–disease relationships to illuminate molecular mechanisms underlying variable susceptibility and environmentally influenced diseases. These data provide insights into complex chemical–gene and protein interaction networks. (http://ctd.mdibl.org)
- GenePattern: GenePattern is a powerful genomic analysis platform developed at the Broad Institute. It provides access to more than 150 tools for gene expression, RNA-seq, proteomics, and SNP analysis; flow cytometry; and common data processing tasks. A web-based interface provides easy access to these tools and allows the creation of multi-step analysis pipelines that enable reproducible in silico research. (http://www.broadinstitute.org/genepattern)
- Genomatix: Genomatix is a leading commercial supplier of technologies to analyze and interpret genomic data. It is based in Munich, Germany and has its US office in Ann Arbor. In particular, MatInspector is Genomatix’ widely used program for identification of transcription factor binding sites. MatBase is a comprehensive transcription factor knowledge base.
