Methods:The luciferase reporter plasmids of MDM2 P2 promoter containing different SNP309 were contructed,and cotransfected into CV-1 cells with AML1-ETO,AML1 and SP1 expression plasmid.The transactivities of luciferase were assayed by luminometer to determine the impact of AML1,AML1-ETO,and SP1 on MDM2 P2 promoter.

研究方法：构建含不同SNP309位点的MDM2 P2启动子的报告质粒，与AML1-ETO、AML1以及SP1的表达质粒单独或共转染CV-1细胞，测定荧光素酶的活性，分析AML1-ETO、AML1以及SP1对MDM2 P2启动子的影响。

Firstly, the pGL3-Control vector was reconstructed , the pGL3-Enhancer vector deletious of SV40 promoter gene was obtained . Then the IFN-β promoter gene was cloned into the pGL3-Enhancer vector and pGL-IP21, the Luciferase reporter plasmid with IFN-β promoter was OK. The availability of pGL-IP21 was verified by NDV ,the inductor of IFN-β, the Luciferase activity was assayed in cells transfected with pGL-IP21 by Luminometer.
