Regulatory mechanisms underlying endoplasmic reticulum stress involvement in the development of gestational diabetes mellitus entail the CHOP-PPARα-NF-κB pathway.

Objective: We investigated the proinflammatory functions of endoplasmic reticulum stress and peroxisome proliferator-activated receptor α (PPARα) in the development of gestational diabetes mellitus (GDM) and their relationship in regulating inflammation in GDM.

Methods: This study was performed on placentas of normal pregnant women, women with GDM, and HTR8 cells. Transmission electron microscopy, immunohistochemistry, Western blot analysis, and RT-PCR were performed to analyze ERS and PPARα expression on both normal and GDM pregnancy placentas.

Modulating circulating sFlt1 in an animal model of preeclampsia using PAMAM nanoparticles for siRNA delivery.

Introduction: Excessive circulating sFlt1 plays a major role in the pathogenesis of preeclampsia (PE). Using RNAi to silence sFlt1 may be a therapy for treating PE. Because of the rapid degradation of siRNA, gene therapy in vivo remains limited.

Upregulation of VEGF by small activating RNA and its implications in preeclampsia.

Introduction: Preeclampsia is a severe pregnancy complication mostly due to inadequate vascular dilation and remodeling of spiral arteries. VEGF, the major factor for angiogenesis, is necessary for modulating angiogenic processes in the placenta. Hence reduction of VEGF in gestational hypertension may also lead to hypoperfusion and subsequent hypoxia of the fetus in hypertensive pregnancy.

Downregulation of Mitofusin 2 in Placenta Is Related to Preeclampsia.

Background. Mitofusin 2 (Mfn2) is a novel mitochondrial protein that is implicated in cellular proliferation and metabolism; however, the role of Mfn2 in preeclampsia (PE) remains unknown. This study aimed to explore the relationship between Mfn2 and PE.
