Effects of angiotensin Ⅱ on ATP binding cassette transporter A1 in THP-1 derived foam cells / 中国病理生理杂志

ABSTRACT

AIM:To study the influence of angiotensin Ⅱ(AngⅡ) on ATP-binding cassette transporter A1 in THP-1 derived foam cells.The variance of the expression of ABCA1,the content and the effluent rate of cholesterol were also investigated.METHODS: The regulatory effect of AngⅡ on the expression of ABCA1 mRNA and protein in THP-1 derived form cells were measured by RT-PCR and Western blotting.The effect of variance of cholesterol content was measured by zymochemistry via-fluorospectrophotometer,cholesterol effluent was measured by liquid scintillator.RESULTS: A positive facilitative effect of Ang Ⅱon form cells was observed.Total cholesterol content were increased significantly by Ang Ⅱ treatment(P
