Objective To investigate the role and mechanism of microRNA-223( miR-223) in downregulation of high mobility group box 1( HMGB1) secretion from human arterial smooth muscle cells( HASMCs). Methods HASMCs were isolated from the normal arteries of severe traumatic amputees or healthy donors without arteriosclerosis obliterans by tissue explants adherent and then identified by immunofluorescence assay of SM-α actin. Real-time quantitative PCR( RT-q PCR) and Western blotting were used to detect the activity of ...
