| 値 | Superoxide dismutase 3 (SOD3) is a SOD isozyme and plays a key role in extracellular redox homeostasis. We previously demonstrated that histone acetylation is involved in 12-O-tetra-decanoylphorbol-13-acetate (TPA)-elicited SOD3 expression in human monocytic THP-1 cells; however, the molecular mechanisms responsible for its expression have not yet been elucidated in detail. The results of the present study demonstrated that the binding of histone deacetylase 1 (HDAC1) to the SOD3 promoter region contributed to SOD3 silencing in basal THP-1 cells. On the other hand, the dissociation of HDAC1 from the SOD3 promoter region and the enrichment of p300, a histone acetyltransferase (HAT), within that region were observed in TPA-induced THP-1 cells. Myocyte enhancer factor 2 (MEF2) functions as a scaffold protein that interacts with histone deacetylases (HDAC) or HAT and regulates gene expression. The present results showed that the MEF2A and MEF2D function as mediators for TPA-elicited SOD3 expression by interacting with HDAC or p300. Additionally, the knockdown of MEF2A or MEF2D in human skin fibroblasts suppressed SOD3 expression at the mRNA and protein levels. Our results provide an insight into epigenetic regulation of redox gene expression, and may ultimately contribute to suppressing the progression of tumours and vascular diseases. | |||||
