Tissue-specific enhancer-promoter interactions regulate high level constitutive expression of matrix metalloproteinase 2 by glomerular mesangial cells.

Abstract excerpt

The 72-kDa gelatinase A (MMP-2) is a central mediator of the response of the intrinsic glomerular mesangial cell to inflammatory stimuli and is regulated in a unique, cell-specific manner. We isolated a 6-kilobase pair genomic fragment of the rat MMP-2 gene and sequenced and characterized 1686-base pair of the 5'-flanking region. Using a series of 5' deletion constructs of the proximal 5'-flanking region, a...
