Abstract
Background: Overexpression of sFlt-1 or modulation of FKBPL, key antiangiogenic proteins, are important in the pathogenesis of preeclampsia.
Methods: A newly developed nonviral gene-delivery system, RALA, capable of overexpressing sFlt-1 (e15a isoform) was delivered in vivo in transgenic haploinsufficient (Fkbpl+/−) mice. RALA was also used in vitro to deliver human Flt1 (hFlt1) in trophoblast cells.
Results: Serum stable and nontoxic RALA/DNA-based nanoparticles induced an increase in sFlt-1 protein levels in the blood and total protein in the urine; the effect was more pronounced in Fkbpl+/− mice. In vitro, RALA-hFlt nanoparticles significantly reduced secretion of sFlt-1 in trophoblast cells.
Conclusion: The RALA-based genetic nanodelivery system can be safely and effectively applied to emulate preeclampsia-like features or reduce sFlt-1 levels in vitro.
