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.
WebJul 9, 2024 · I've also been giving fgsea a shot, and it definitely seems to be fairly powerful, allowing me to programmatically run enrichment algorithms for multiple genesets at once.
