Regulation of histone modifications in diabetic wound healing, by mediating macrophage-mediated inflammation. The modification site and modification type are shown on H3 and H4. MOF can acetylate lysine 16 on the histone H4 (H4K16) and regulate NF-κB-mediated inflammatory cytokine expression, thus leading to inflammation and delayed diabetic wound healing. MLL1 can methylate lysine 4 on histone H3 (H3K4) and regulate the COX-2/PGE2 pathway, promoting the expression of inflammatory cytokines, thus leading to inflammation and delayed diabetic wound healing. Setdb2 can methylate lysine 9 on histone 3 (H3K9) and regulate NF-κB-mediated inflammatory cytokine expression and production of uric acid, thus leading to inflammation and delayed diabetic wound healing. JMJD3 can demethylate the lysine 27 site on histone 3 (H3K27) to regulate NF-κB-mediated inflammatory cytokine expression, modulating inflammation and causing delayed diabetic wound healing.
