Enrichment plots and heat maps for the gene sets of dendrite, ATPase activity coupled to ion transmembrane movement and cytoskeleton dependent intracellular transport generated by GSEA. (A) Enrichment plot for the gene set of dendrite. Y-axis: value of the ranking metric; X-axis: the rank for all genes. Bottom: plot of the ranked list of all genes. Genes whose expression levels are most closely associated with the HAD or HIV non-dementia group are located at the left or right edge of the list while genes from the gene set dendrite within the ranked list are located at the middle. Top: the running enrichment score for the gene set as the analysis walks along the ranked list. The score at the peak of the plot is the enrichment score (ES) for this gene set and those genes appear before or at the peak are defined as core enrichment genes for this gene set. (B) Heat map of the core enrichment genes of the dendrite gene set, which contributes most to the ES. Rows: gene; columns: samples. Range of colors (red to blue) indicates the range of expression values (high to low). (C) Enrichment plot for the gene set of ATPase activity coupled to ion transmembrane movement. (D) Heat map of the core enrichment genes of the gene set ATPase activity coupled to ion transmembrane movement. (E) Enrichment plot for the gene set of cytoskeleton dependent intracellular transport. (F) Heat map of the core enrichment genes of the gene set cytoskeleton dependent intracellular transport.
