Placental homing peptide guides HIF1α‑silenced exosomes conjugates for targeted enhancement of invasion of trophoblast cells.

ABSTRACT: There is a current lack of availability of therapeutics to treat Preeclampsia (PE), primarily due to the risk of harm to the fetus. Hypoxia‑inducible factor‑1α (HIF1α) is highly expressed in trophoblast cells and suppresses their invasive ability. Extensive studies have confirmed the positive effects of mesenchymal stem cell (MSC)‑derived exosomes on PE. The aim of the present study was to develop a method for targeted delivery of HIF1α‑silenced exosomes to the placenta. HIF1α was overexpressed in JEG‑3 cells. Then, the glucose uptake, lactate production, proliferation and invasion of HIF1α‑elevated JEG‑3 cells were detected. Exosomal membrane protein lysosome‑associated membrane glycoprotein 2b and placental homing peptide CCGKRK gene sequence amplified by PCR were conjugated using short
