Elevated microRNA-520g in pre-eclampsia inhibits migration and invasion of trophoblasts

Elevated maternal serum level of miR-520g level in first trimester was detected in patients with severe PE. By suppressing the migration and invasion of trophoblast via at least partial inhibition of MMP2 translation inhibition, miR-520g might play a role in the defective spiral artery remodeling, and thus contribute to pre-eclampsia pathophysiology.
