WebOrigins of GSEA GSEA was first described by Mootha et al. (Mootha 2003) in an attempt to shed light on the mechanistic basis of Type 2 diabetes mellitus. They reasoned that alterations in gene expression associated with a disease can manifest at the level of biological pathways or co-regulated gene sets, rather than individual genes. WebGSEA MSigDB Molecular Signatures Database Overview 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.
