Purpose To identify the binding of hypoxia inducible factor-2α( HIF-2α) to the hypoxia-response element( HRE) of the matrixmetallo proteinases-2( MMP-2) gene promoter region and clear the binding site. Methods Electrophoretic mobility shift assay( EMSA) was used to identify the binding of HIF-2α to HRE of the MMP-2 gene promoter region in vitro. At the same time,the chromatin immunoprecipitation assay( CHIP) was used to further determine the binding site.Results Successful prediction of two potential HIF-2α...
