Paternal Expressed Gene 10 (PEG10) is decreased in early-onset preeclampsia

Abstract

Background: Preeclampsia is a severe complication of pregnancy which is attributed to placental dysfunction. The retrotransposon, Paternal Expressed Gene 10 (PEG10) harbours critical placental functions pertaining to placental trophoblast cells. Limited evidence exists on whether PEG10 is involved in preeclampsia pathogenesis. This study characterised the expression and regulation of PEG10 in placentas from patients with early-onset preeclampsia compared to gestation-matched controls. Methods: PEG10 expression was measured in plasma and placentas collected from patients with early-onset preeclampsia (< 34 weeks’) and gestation-matched controls using ELISA (protein) and RT-qPCR (mRNA).
