1. Abstract

Syncytin-1 serves as an enveloped membrane glycoprotein encoded from env gene and expressed in placenta specifically as HERV-W member product of human genome playing an essential role in cell fusion process of from trophoblast to syncytiotrophoblast during each individual pregnancy. It is widely maintained that unusual expressive levels of syncytin-1 have close relationships to obstetrical syndromes such as pre-eclampsia as a typical gestational hypertension symptom. In this review, correlations between syncytin-1 and related diseases are in detailed discussions.
