msigdbr: MSigDB Gene Sets for Multiple Organisms in a Tidy Data Format

Description

Provides the 'Molecular Signatures Database' (MSigDB) gene sets typically used with the 'Gene Set Enrichment Analysis' (GSEA) software (Subramanian et al. 2005 doi:10.1073/pnas.0506580102, Liberzon et al. 2015 doi:10.1016/j.cels.2015.12.004, Castanza et al. 2023 doi:10.1038/s41592-023-02014-7) as an R data frame. The package includes the human genes as listed in MSigDB as well as the corresponding symbols and IDs for frequently studied model organisms such as mouse, rat, pig, fly, and yeast.

Retrieve the gene sets data frame

Description

Retrieve a data frame of gene sets and their member genes. The original human genes can be converted into their corresponding counterparts in various model organisms, including mouse, rat, pig, zebrafish, fly, and yeast. The output includes gene symbols along with NCBI and Ensembl IDs.

Usage

msigdbr(
  db_species = "HS",
  species = "human",
  collection = NULL,
  subcollection = NULL,
  category = deprecated(),
  subcategory = deprecated()
)

Arguments

Details

Historically, the MSigDB resource has been tailored to the analysis of human-specific datasets, with gene sets exclusively aligned to the human genome. Starting with release 2022.1, MSigDB incorporated a database of mouse-native gene sets and was split into human and mouse divisions ("Hs" and "Mm"). Each one is provided in the approved gene symbols of its respective species.

Mouse MSigDB includes gene sets curated from mouse-centric datasets and specified in native mouse gene identifiers, eliminating the need for ortholog mapping.

Value

A tibble (a data frame with class tibble::tbl_df) of gene sets with one gene per row.

Examples

# Get all human gene sets
gs <- msigdbr()
head(gs)

# Get all mouse gene sets
gs <- msigdbr(db_species = "MM", species = "Mus musculus")
head(gs)

# Get CGP (chemical and genetic perturbations) gene sets with genes mapped to rat orthologs
gs <- msigdbr(species = "Rattus norvegicus", collection = "C2", subcollection = "CGP")
head(gs)
