A single nucleotide polymorphism in the matrix metalloproteinase-1 (MMP-1) promoter influences amnion cell MMP-1 expression and risk for preterm premature rupture of the fetal membranes.

Abstract excerpt

Interstitial collagen gives fetal membranes tensile strength, and membrane rupture has been attributed to collagen degradation. A polymorphism at -1607 in the matrix metalloproteinase-1 (MMP-1) promoter (an insertion of a guanine (G)) creates a core Ets binding site and increases promoter activity. We investigated whether this polymorphism is functionally significant for MMP-1 expression in amnion cells and...
