Overexpression of miR-21 and miR-122 in preeclamptic placentas.

Abstract

The apoptosis-associated miRNAs miR-21 and miR-122 are dysregulated in the term preeclamptic placentas. The increased miRNA expression suggest the downregulation of potential targets mRNAs, which can contribute to the pathogenesis of preeclampsia. The identification of their targets in placenta will improve our understanding of their role in preeclampsia.
