Abstract:Objective To investigate the effect of siRNA on Akt1 gene expression in endothelial cells,and its influence on the migration of endothelial cells induced with lung carcinoma A549 cells conditioned medium(CM).Methods Using human umbilical vein endothelial cells (HUVECs) as the target cells,a siRNA sequence targeted Akt1 gene(siAkt1) was designed and trafected into HUVECs
