The Molecular Signature Database (MSigDB) is a collection of gene sets maintained by the GSEA team. The team welcomes and appreciates contributions to this shared resource and encourages users to submit their gene sets to mailto:gsea@broad.mit.edu. The MSigDB contains four categories of genes sets. Our thanks to the contributors.

These gene sets can be helpful in identifying effects related to epigenetic silencing, dosage compensation, copy number polymorphisms, and aneuploidy or other chromosomal deletions/amplifications.

In addition, contains gene sets representing gene expression signatures of genetic and chemical perturbations that have been culled from experimental results in the literature.

Several colleagues have contributed to this effort, including:

Jean-Pierre Bourquin (Orkin lab)
Ben Ebert (Golub lab)
Yujin Hoshida (Golub lab)
Jean Junior (Student)
John Newman (L2L, Washington University)
Kate Stafford (MIT, UROP)
Lisa Sturla (Pomeroy lab)

Please see the annotation of a gene set in its GeneSetCard or the MSigDB Browser included in the GSEA java desktop application for the source/contributor of a gene set.

The motifs are catalogued in Xie, et al, 2005 and Supplemental Information and represent known or likely regulatory elements in promoters and 3'-untranslated regions.

Database C4, Computed (correlational): Correlation gene sets are groups of genes defined by computationally mining large-scale experimental datasets for co-expressed genes built from the neighborhoods of ~400 cancer related genes (seeds).
