I/R induces release of acetylated-HMGB1 from hepatocytes through HDAC1 deactivation and HDAC4 shuttling. The proposed model showing release of acetylated HMGB1 following I/R. Both de-activation of nuclear HDAC1 and cytosplasmic shuttling of HDAC4 contribute to a reduction in overall nuclear HDAC activity, tilting the acetylation/deacetylation balance of HMGB1 toward net acetylation and release.
