Abstract

Lower extremity artery disease (LEAD) is an underestimated chronic vascular disease caused by the formation of atherosclerotic plaques in the lower limb arteries. The pathological processes underlying this disease are regulated by many various factors, including microRNAs (miRNAs). miRNAs constitute a pool of small, non-coding RNAs with a gene expression modulatory function. In the presented study, differentially expressed miRNAs were identified in peripheral blood mononuclear cells from 18 patients with LEAD compared to 10 healthy volunteers using OpenArray RT-qPCR. Sixteen miRNAs were significantly differentially expressed in the LEAD group. Four out of them, hsa-miR-138-5p, -34a-3p, -34a-5p, and -766-3p, were consistent with a previous next-generation sequencing study. The in silico analysis performed for these four miRNAs showed associations with vascular smooth muscle cells differentiation, inflammation, and apoptosis, potentially resulting from modulation of genes involved in cell cycle, cellular adhesion, and Notch signaling. The presented study expands our knowledge on the role of miRNA in the pathology of LEAD, providing potential candidates for biomarkers of this disease.
