ABSTRACT
<p><b>OBJECTIVE</b>To investigate the effect of anti-miR-145 on human airway smooth muscle cell (HASMC) proliferation and osteopontin systhesis in vitro and explore the mechanisms.</p><p><b>METHODS</b>HASMCs were treated with 10-100 nmol/L anti-miR-145, and the cell proliferation and apoptosis were investigated using a CCK-8 assay and flow cytometry, respectively. The changes in osteopontin synthesis after the treatment was quantified with Western blotting.</p><p><b>RESULTS</b>Treatment with 10 and 50 nmol/L anti-miR-145 significantly promoted the proliferation and osteopontin synthesis in HASMCs (P<0.05 or <0.01), and 50 nmol/L anti-miR-145 obviously inhibited the cell apoptosis (P<0.01).</p><p><b>CONCLUSION</b>Anti-miR-145 promotes HASMC proliferation and osteopontin synthesis and inhibits HASMC apoptosis in vitro, indicating the important role of anti-miR-145 in the pathogenesis of airway remodeling.</p>
