Circulating Exosomal Mir21 And Mir320 In Obstructive Sleep Apnea
Resumen: Rational. Epidemiological studies indicate that there may be an association between obstructive sleep apnea (OSA) and cardiovascular and metabolic diseases. Some pro-inflammatory miRs (miR-21, miR320) critical for the immune response or hypoxia are often overexpressed in cancers and atherosclerosis. Aim. To examine the expression of miR-21& miR320 in circulating exosomes from patients with OSA. Methods: From a Sleep Unit and in the frame of a long-term longitudinal cohort study we selected 65 non-smokers OSA patients (apnea-hypopnea index -AHI- 30 events/ti) and 26 age, gender and BMI-matched controls (AHI < 5). All participants were free of comorbidities other than OSA at baseline (GovTrials, NCT014575421). At recruitment and yearly, carotid ultrasound was performed and subclinical atherosclerosis (SA) was defined as by the presence of carotid plaques of by an intima-media thickness > 0.85 mm. Plasma-derived exosomes were isolated by precipitation using miRCURY, , , Exosome Isolation Kit. Exosomes were characterized by transmission electron microscopy, dynamic light scattering assay and Western Blot analysis using CD63 and HSP70. Exosome total RNA was obtained using miRCURY"* RNA isolation kit. miR-21 -5p and miR-320-3p were analysed by real time quantitative PCR (RT-qPCR) using miRCURY LNA~ technology...
