Objective To investigate the effect of mutant c-myc on vascular smooth muscle cells(VSMC) migration and invasion.Methods Western blot analysis,luciferase assay,and VSMC migration and invasion assay were used to determine c-myc protein expression,c-myc transcriptional activity,and VSMC migration and invasion ability.Result c-myc protein levels and transcriptional activity were significantly increased in VSMC when transfected with mutant c-myc(T58A,S62A) or wild type(WT) c-myc gene.VSMC migration and invasion...
