Abstract

INTRODUCTION: Preeclampsia is a serious complication of pregnancy affecting 5% of pregnancies. Our team identified 137 genes highly expressed in placenta relative to other human tissues. Here, we have explored a role for steroid sulfatase (STS) in preeclampsia by characterising STS expression and the functional effects of STS on primary placental trophoblasts. METHODS: Characterisation of STS was performed on preterm preeclamptic and gestation-matched normotensive preterm controls who delivered at <34 weeks gestation. We characterised placental and maternal whole blood STS mRNA and placental protein expression via qRT-PCR, immunohistochemistry and Western Blot. To assess whether STS is invol..
