MicroRNA-mediated mechanisms of the cellular stress response in atherosclerosis

| Atherosclerosis is characterised by the accumulation of lipid-laden macrophages in atherosclerotic lesions and occurs preferentially at arterial branching points, which are prone to inflammation during hyperlipidaemic stress. The increased susceptibility at branching sites of arteries is attributable to poor adaptation of arterial endothelial cells to disturbed blood flow. In the past 5 years, several studies have provided mechanistic insights into the regulatory roles of microRNAs (miRNAs) in inflammatory activation, proliferation, and regeneration of endothelial cells during this maladaptive process. The intercellular transfer of vesicle-bound miRNAs contributes to arterial homeostasis, and the combinatorial effect of multiple miRNAs controls the unresolved inflammation orchestrated by macrophages in atherosclerotic lesions. In this Review, we highlight the miRNA-dependent regulation of the endothelial phenotype and the proliferative reserve that occurs in response to altered haemodynamic conditions as a prerequisite for atherogenic inflammation. In particular, we discuss the regulation of transcriptional modules by miRNAs and the protective role of complementary strand pairs, which encompasses remote miRNA signalling. In addition, we review the roles of miRNA tandems and describe the relevance of RNA target selection and competition to the behaviour of lesional macrophages. Elucidating miRNA-mediated regulatory mechanisms can aid the development of novel diagnostic and therapeutic strategies for atherosclerosis. Schober, A. et al. Nat. Rev.

“…Importantly, microRNA-144 levels were increased in the plasma of mouse and humans subjected to limb RIC. Plasma carriage of microRNAs, to prevent digestion by circulating RNase, has been demonstrated within lipoprotein complexes in association with specific carrier proteins, such as argonaute, and in exosomes (56–59). Interestingly, the total number of exosomes in mouse plasma after RIC did not increase (60), although others observed increased numbers of exosomes following RIC in both rats and humans (61).…”

In remote ischemic conditioning (RIC) brief, reversible episodes of ischemia with reperfusion in one vascular bed, tissue or organ confer a global protective phenotype and render remote tissues and organs resistant to ischemia/reperfusion injury. The peripheral stimulus can be chemical, mechanical or electrical and involves activation of peripheral sensory nerves. The signal transfer to the heart or other organs is through neuronal and humoral communications. Protection can be transferred, even across species, with plasma-derived dialysate and involves nitric oxide, stromal derived factor-1α, microRNA-144, but also other, not yet identified factors. Intracardiac signal transduction involves: adenosine, bradykinin, cytokines, and chemokines, which activate specific receptors; intracellular kinases; and mitochondrial function. RIC by repeated brief inflation/deflation of a blood pressure cuff protects against endothelial dysfunction and myocardial injury in percutaneous coronary interventions, coronary artery bypass grafting and reperfused acute myocardial infarction. RIC is safe and effective, noninvasive, easily feasible and inexpensive.

MicroRNAs (miRNAs) are small non-coding RNAs that negatively regulate gene expression at the post-transcriptional level. They are involved in important biological processes including development, homeostasis, and ageing. Recently, extracellular miRNAs have been discovered in the bloodstream and bodily fluids. These miRNAs are shown to be secreted and circulating in microvesicles (MVs), or in complex with other factors such as RNA-binding proteins and high-density lipoprotein (HDL) particles. These cell-free, circulating miRNAs can be taken into and function as negative regulators of target genes in recipient cells. Here we review the biogenesis and uptake of circulating miRNAs as well as their profiles in ageing and ageing-related diseases. We discuss the emerging role of circulating miRNAs as biomarkers and therapeutic targets.
