Abstract

Background:Histone deacetylase (HDAC) inhibition promotes bone formationin vitrovia undefined epigenetic events. Results:Microarray and ChIP-Seq analyses revealed genomic areas where H4 acetylation is altered by HDAC inhibitors and identified differentially regulated genes. Conclusion:Suberoylanilide hydroxamic acid increases H4 acetylation and suppresses phosphorylation of insulin/Akt signaling mediators in osteoblasts. Significance:Epigenetic profiling is a powerful means to gain mechanistic insights into bone anabolic processes.
