Knockdown of Aurora kinase B alleviates high glucose-triggered trophoblast cells damage and inflammation during gestational diabetes.

Abstract

This research investigates how Aurora kinase B (AURKB) functions in trophoblast cells when they are exposed to high levels of glucose during gestational diabetes. The findings from RT-qPCR and western blotting show that when in a high-glucose environment, AURKB expression increases in both the placenta and trophoblast cells of patients with gestational diabetes mellitus. Additionally, when AURKB is silenced in high-glucose conditions, it leads to boosted proliferation of trophoblast cells and reduced inflammation. Knockdown of AURKB inhibits the expression of phosphoinositide 3-kinase (PI3K)/protein kinase B (AKT) pathway in high glucose (HG) environment. Knockdown of AURKB may ameliorate injury and inflammatory responses in HG-exposed trophoblast cell lines in part by regulating the PI3K/AKT signaling pathway.
