Matrix metalloproteinase-7 A-181G and its interaction with matrix metalloproteinase-9 C-1562T polymorphism in preeclamptic patients: association with malondialdehyde level and severe preeclampsia.

Purpose The abnormal activation of matrix metalloproteinases (MMPs) during pregnancy might be involved in the pathogenesis of preeclampsia. The aim of present study was to investigate the possible influence of MMP-7 A-181G and its interaction with MMP-9 C- 1562T polymorphism on the risk of preeclampsia and lipid peroxidation level.
