Although it is well known that nitrofen induces congenital diaphragmatic hernia (CDH), including CDH-associated lung hypoplasia and pulmonary hypertension (PH) in rodents, the mechanism of pathogenesis remains largely unclear. It has been reported that pulmonary artery (PA) endothelial cell (EC) dysfunction contributes to the development of PH in CDH. Thus, we hypothesized that there is significant alteration of endothelial dysfunction-associated proteins in nitrofen-induced CDH PAs. Pregnant SD rats received either nitrofen or olive oil on gestational day 9.5. The newborn rats were sacrificed and divided into a CDH (n = 81) and a control (n = 23) group. After PA isolation, the expression of PA endothelial dysfunction-associated proteins was assessed on Western blot and immunostaining. We demonstrate that the expression of C-reactive protein and endothelin-1 and its receptors, ETA and ETB, were significantly increased in the CDH PAs. Levels of phosphorylated myosin light chain were significantly elevated, but those of phosphorylated endothelial nitric oxide synthase, caveolin-1, and mechanistic target of rapamycin were significantly decreased in the CDH PAs. In this work, we elucidate alterations in the expression of endothelial dysfunction-associated proteins specific to nitrofen-induced CDH rodent PAs, thereby advancing our understanding of the critical role of endothelial dysfunction-associated pathways in the pathogenesis of nitrofen-induced CDH.
