“Rapid changes in histone deacetylases and inflammatory gene expression in expert meditators” “In contrast (to a control group), after the brief intervention we detected reduced expression of histone deacetylase genes (HDAC 2, 3 and 9), alterations in global modification of histones (H4ac; H3K4me3) and decreased expression of pro-inflammatory genes (RIPK2 and COX2) in meditators compared.
