Endothelial Dicer promotes atherosclerosis and vascular inflammation by miRNA-103-mediated suppression of KLF4

Abstract

The RNAse III endonuclease Dicer is crucial for processing of pre-miRNAs in health and disease. Here the authors show that endothelial Dicer promotes atherosclerosis by increasing miR-103 levels leading to suppression of the anti-inflammatory transcription factor KLF4, thus suggesting a novel approach to treat this disease.
