Molecular Signatures Database


The Molecular Signatures Database (MSigDB) is a resource of tens of thousands of annotated gene sets for use with GSEA software, divided into Human and Mouse collections. From this web site, you can

  • Examine a gene set and its annotations. See, for example, the HALLMARK_APOPTOSIS human gene set page.
  • Browse gene sets by name or collection.
  • Search for gene sets by keyword.
  • Investigate gene sets:
    • Compute overlaps between your gene set and gene sets in MSigDB.
    • Categorize members of a gene set by gene families.
    • View the expression profile of a gene set in a provided public expression compendia.
    • Investigate the gene set in the online biological network repository NDEx
  • Download gene sets.

Citing the MSigDB

To cite your use of the Molecular Signatures Database (MSigDB), a joint project of UC San Diego and Broad Institute, please reference Subramanian, Tamayo, et al. (2005, PNAS) and one or more of the following as appropriate: Liberzon, et al. (2011, Bioinformatics), Liberzon, et al. (2015, Cell Systems), and also the source for the gene set as listed on the gene set page. If you use Mouse MSigDB, please also cite Castanza, et al. (2023, Nature Methods).


GSEA and MSigDB are currently funded by a grant from NCI's Informatics Technology for Cancer Research (ITCR)
