Activated PRDM1-CREBBP contributes to preeclampsia by regulating apoptosis and invasion of the human trophoblast cells.

ABSTRACT: Preeclampsia (PE) is a multifactorial disorder of pregnancy, characterized by new-onset gestational hypertension. High-throughput mRNA sequencing (RNA-seq) was performed to analyze the gene expression patterns in placentas from patients with early-onset PE (EOPE). PR domain zinc-finger protein 1 (PRDM1) expression increased in the chorionic villi and placental basal plate from patients with PE and nitro-l-arginine methyl ester (L-NAME)-treated rats. Inhibition of PRDM1 enhanced trophoblast/extravillous trophoblast (EVT) cell invasion/migration and reduced apoptosis under hypoxia/reoxygenation (H/R) conditions. RNA-seq data indicated that the expression of CREB-binding protein (CREBBP), a transcriptional coactivator, was upregulated in preeclamptic placentas and showed a positive cor
