摘要

目的小鼠单核细胞趋化蛋白-1（monocyte chemoattractant protein-1， MCP-1）启动子的克隆及其活性分析。方法从小鼠巨噬细胞株ANA-1中分别扩增一长一短2个小鼠MCP-1启动子片段，并克隆入虫荧光素酶报告基因载体中。2个不同长度的MCP-1启动子片段重组报告基因质粒分别与类法尼醇X受体(farnesoid X receptor

FXR)真核表达质粒共转染HEK293细胞中，经鹅脱氧胆汁酸(chenodeoxycholic acid

CDCA)处理后，检测荧光素酶活性。结果小鼠MCP-1启动子报告基因载体构建成功。经CDCA处理后，转染FXR表达质粒可下调2个不同长度的MCP-1启动子活性，且下调幅度相当。结论激活FXR可能通过小鼠MCP-1基因启动子-322～+82 bp区域FXR负性结合元件而下调该基因转录活性。

Abstract

Objective To clone the mouse monocyte chemoattractant protein-1 (MCP-1) promoter and analyze its activity. Methods Two promoter fragments of mouse MCP-1 gene were amplified from murine macrophage cell line ANA-1 and then cloned into luciferase reporter vector. They were respectively transfected with or without farnesoid X receptor (FXR) expression vector into HEK293 cells. The luciferase activity of transfected HEK293 after the treatment of chenodeoxycholic acid (CDCA

50 μmol/L) was determined with chemiluminescent analysis and normalized against β-galactosidase activity. Results The 2 luciferase reporter vectors of MCP-1 promoter were successfully constructed. After treatment with CDCA

FXR expression vector transfection equivalently down-regulated the promoter activity of both mouse MCP-1 promoter fragments in HEK293 cells. Conclusion Activated by CDCA

FXR may down-regulate the activity of mouse MCP-1 promoter through negative FXR element which lies between position -322 and +82 bp.
