Decreased expression and DNA methylation levels of GATAD1 in preeclamptic placentas.

ABSTRACT: Expression of syncytin-1, or the human endogenous retroviral family W member 1 (HERVWE1) in human placental trophoblasts is regulated by DNA methylation. Increased DNA methylation and decreased expression of syncytin-1 have been observed in preeclamptic placentas. The syncytin-1-mediated fusogenic as well as non-fusogenic activities, e.g., cell cycle promotion, anti-apoptosis, and immune suppression, are implicated in the pathogenic changes in preeclamptic placentas. It is noteworthy that in a close vicinity to syncytin-1 there are two genes, peroxisome biogenesis factor 1 (PEX1) and GATA zinc finger domain containing 1 (GATAD1), as well as multiple CpG islands around these genes. In this study we determined if these adjacent genes might, like syncytin-1, subject to epigenetic regulation i
