Shear stress sustains atheroprotective endothelial KLF2 expression more potently than statins through mRNA stabilization.
OBJECTIVE The transcription factor KLF2 is considered an important mediator of the anti-inflammatory and anti-thrombotic properties of the endothelium. KLF2 is absent from low-shear, atherosclerosis-prone sites of the vascular tree but is induced by HMG-CoA reductase inhibitors (statins) in vitro. We studied KLF2-dependent induction of important determinants of the atheroprotective status of th...
متن کاملGlyc-oxidized LDL impair endothelial function more potently than oxidized LDL: role of enhanced oxidative stress.
Hypercholesterolemia is associated with impairment of endothelial function due to increased levels of LDL. In diabetic patients, however, attenuation of endothelial function occurs even under normocholesterolemic conditions. Here we assessed whether glycation of LDL potentiates their influence on endothelial function, with particular emphasis on the oxidizability of LDL and the role of O2-. Hum...
متن کاملMolecular Cardiology Flow-Dependent Regulation of Krüppel-Like Factor 2 Is Mediated by MicroRNA-92a
Background—Upregulated by atheroprotective flow, the transcription factor Krüppel-like factor 2 (KLF2) is crucial for maintaining endothelial function. MicroRNAs (miRNAs) are noncoding small RNAs that regulate gene expression at the posttranscriptional level. We examined the role of miRNAs, particularly miR-92a, in the atheroprotective flow–regulated KLF2. Methods and Results—Dicer knockdown in...

متن کاملAtheroprotective mechanisms of shear stress-regulated microRNAs.
MicroRNAs (miRs) are small non-coding RNAs that control gene expression by inhibiting translation or inducing degradation of targeted mRNA. miRs play a crucial role in vascular homeostasis but also during pathophysiological processes. Functionally active endothelial cells maintain homeostasis of the vasculature and protect against cardiovascular disease. The mechanical activation of endothelial...
