Fig. 6From: Epigenome-wide DNA methylation profiling of conditioned pain modulation in individuals with non-specific chronic low back painOverlap of significantly enriched (p < 0.05) gene ontologies (GO) and functional pathways from annotated differentially methylated genes (DMG) in chronic low back pain (CLBP) and pain-free control (PFC) groups. Venn diagram shows numbers of unique and overlapping biological processes, cellular components, molecular functions, KEGG pathways, and wikipathways enriched by annotated differentially methylated genes between efficient and deficient conditioned pain modulation comparing CLBP to PFC groups. The red circle represents the number of significant GO or pathways within the PFC group; the yellow circle represents the number of significant GO and pathways within the CLBP groupBack to article page
