    MSigDB (Molecular Signatures Database) gene sets derived from a variety of curated sources

  description: |
    The Curated (C2) collection of the Molecular Signatures Database (MSigDB) 
    comprises gene sets derived from canonical pathway databases (such as KEGG, 
    Reactome, and BioCarta) and from gene expression studies in the literature. 
    These sets represent well-defined biological pathways, signaling cascades, 
    and experimentally derived perturbation signatures. The C2 collection 
    enables systematic assessment of how experimental gene expression profiles 
    align with established biological knowledge.
