WebAug 2, 2024 · Gene Set Enrichment Analysis (GSEA) is a common method to analyze RNA-Seq data that determines whether a predefined defined set of genes (for example those in a GO term or KEGG pathway) show statistically significant and concordant differences between two biological phenotypes. WebNov 9, 2016 · Deregulated pathways identified from transcriptome data of two sample groups have played a key role in many genomic studies. Gene-set enrichment analysis (GSEA) has been commonly used for pathway or functional analysis of microarray data, and it is also being applied to RNA-seq data. However, most RNA-seq data so far have only …
