Circulating microRNAs in Carotid Atherosclerosis: Complex Interplay and Possible Associations with Atherothrombotic Stroke.

ABSTRACT: Atherosclerosis is a chronic inflammatory disorder which remains the main cause of cardiovascular morbidity and mortality, with carotid atherosclerosis (CA) being a major cause of ischemic stroke. Epigenetic regulation plays a significant role in CA progression and stroke, yet the impact of circulating microRNA expression, associated with atherogenesis, has not been clearly defined. We included 81 patients with moderate-severe CA (mean age 67 ± 7 years, 53% male), 42% of whom had prior ipsilateral ischemic stroke (i.e., were symptomatic). A total of 24 miRs were identified and their plasma expression levels were measured. We observed that several microRNAs were up-regulated in stroke survivors, namely miR-200c-3p (30.6 vs. 29.7, p = 0.047), miR-106b-3p (31.01 vs. 30.25, p = 0
