Recent studies have shown that microRNA-23a is down regulated in atherosclerotic tissues. In this study we sought to demonstrate that miR-23a directly binds to 3′ untranslated region of HSP90 mRNA thereby suppressing the expression of its protein. To investigate the potential roles of miR-23a in macrophage, THP-1 macrophages were transfected with miR-23a mimics or inhibitors. Our results showed inflammatory factors IL-6 and MCP-1 concentrations in cell culture medium of macrophages and foam cell transfected with miR-23a mimics were decreased. Furthermore, our findings showed that apoptosis of macrophage and foam cells transfected with miR-23a mimics were inhibited. Over expression of miR-23a in foam cells could reduce lipid intake. Meanwhile, inflammatory macrophages and foam cells transfected with miR-23a mimics, showed a significant decrease in both HSP90 and NF-κB proteins. These results demonstrate a novel finding and potential therapeutic target for atherosclerosis.
