Protein kinase C: A potential therapeutic target for endothelial dysfunction in diabetes

J Diabetes Complications. 2023 Sep;37(9):108565. doi: 10.1016/j.jdiacomp.2023.108565. Epub 2023 Jul 28.

Abstract

Protein kinase C (PKC) is a family of serine/threonine protein kinases that play an important role in many organs and systems and whose activation contributes significantly to endothelial dysfunction in diabetes. The increase in diacylglycerol (DAG) under high glucose conditions mediates PKC activation and synthesis, which stimulates oxidative stress and inflammation, resulting in impaired endothelial cell function. This article reviews the contribution of PKC to the development of diabetes-related endothelial dysfunction and summarizes the drugs that inhibit PKC activation, with the aim of exploring therapeutic modalities that may alleviate endothelial dysfunction in diabetic patients.
