Euglycemic Hyperinsulinemia Increases Blood Pressure in Pregnant Rats Independent of Placental Antiangiogenic and Inflammatory Factors

Although pregnancies associated with hyperinsulinemia and altered placental angiogenic and inflammatory factors are at increased risk for developing preeclampsia, the effects of euglycemic hyperinsulinemia on placental factors and blood pressure regulation during pregnancy are unclear. We hypothesized that chronic hyperinsulinemia results in increased placental soluble fms-like tyrosine kinase 1(sFlt-1) and tumor necrosis factor α (TNF- α) levels and hypertension in pregnant rats.
