The malfunction in the invasion of trophoblastic cells is thought to be fundamental in the cascade of preeclampsia. Also, the role of NO and HO/CO activity in the release of antiangiogenic factors sFlt-1 and sEng is crucial in the pathogenesis of the disease. By blocking these regulatory points, statins beneficially allow the synthesis of NO by eNOS, leading to vasodilation and decrease of the secretion of antiangiogenic factors. The latter effect results in the increase of VEGF and PIGF which are key components in placental and endothelial integrity. eNOS, endothelial nitric oxidase synthase; ET -1, endothelin 1; HO-1/CO, hemeoxygenase -1/ carbon monoxide; NO, nitric oxide; PIGF, placental growth factor; sEng, soluble endoglin; sFlt-1, soluble Fms- like tyrosine kinase; TGF – β, transforming growth factor β; VEGF, vascular endothelial growth factor.
