Relaxin confers cytotrophoblast protection from hypoxia-reoxygenation injury through the phosphatidylinositol 3-kinase-Akt/protein kinase B cell survival pathway.

ABSTRACT: Preeclampsia is a hypertensive syndrome that manifests after 20 wk of gestation. Contemporary understanding of the maternal-fetal interface in preeclampsia suggests a major role for placental oxidative stress resulting from ischemia-reperfusion injury. We hypothesized that the pregnancy hormone relaxin would reduce cytotrophoblast apoptosis and necrosis (aponecrosis) and, hence, the export of placental debris into the maternal circulation. If so, then relaxin might be employed as a therapeutic intervention to diminish the activation of the maternal systemic inflammatory response central to the development of clinical disease. HTR-8/SVneo cells, a model for first trimester extravillous trophoblast, were subjected to serum deprivation and hypoxia or hypoxia-reoxygenation. The cells were trea
