Outline of Final Research Achievements

We performed the analysis of Angptl2 mRNA expression level in aorta of ApoE knockout mice with chronic administration of nicotin using osmotic pumps. The mRNA expression level of Angptl2 in aorta at 6 week after nicotin administration was significantly increased compared with vehicle control. Moreover, the mRNA expression level of Angptl2 in mouse primary endothelial cells with nicotin treatment was also significantly increased compared with control. To investigate whether the development of atherosclerotic plaque with nicotin treatment was dependent on Angptl2, we analyzed the atherosclerotic plaque of Angptl2; ApoE double KO (DKO) mice with 6-week nicotin administration. No differences were observed in size of atherosclerotic plaques of DKO mice between nicotin administration and vehicle group. These data suggested that nicotin induced Angptl2 expression in endothelial cells and then may promote atherosclerotic plaque.
