GSEABase

GSEABase provides R classes and methods for representing and manipulating gene sets and related metadata to support Gene Set Enrichment Analysis (GSEA) within the Bioconductor ecosystem.

Key Features:

• Interoperability: Integrates with other Bioconductor packages to enable combined analyses across the Bioconductor ecosystem.
• Foundational classes and methods: Supplies the essential classes and methods that form the backbone for gene set-based analyses and metadata handling.
• Gene set definitions: Supports defining or importing gene sets based on biological knowledge such as pathways or functional annotations.
• Enrichment analysis support: Provides methodologies for ranking genes and assessing the statistical significance of collective expression changes across conditions.

Scientific Applications:

• Genomics research: Enables identification and interpretation of functional pathways and biological processes perturbed in diseases including cancer, cardiovascular disorders, and neurological conditions.
• Molecular biology studies: Facilitates exploration of molecular mechanisms underlying complex traits and phenotypes using large-scale genomic data.

Methodology:

Provides essential classes and methods for GSEA, enables defining or importing gene sets from biological annotations, and implements methodologies for ranking genes and assessing the significance of their collective expression changes across conditions.
