Abstract
miRNAs are important factors for post-transcriptional process that controls gene expression at mRNA level. Various biological processes, including growth and differentiation, are regulated by miRNAs. miRNAs have been demonstrated to play an essential role in development and progression of hearing loss. Nowadays, miRNAs are known as critical factors involved in different physiological, biological, and pathological processes, such as gene expression, progressive sensorineural hearing loss, age-related hearing loss, noise-induced hearing loss, cholesteatoma, schwannomas, and inner ear inflammation. The miR-183 family (miR-183, miR-96 and miR-182) is expressed abundantly in some types of sensory cells in inner ear specially mechanosensory hair cells that exhibit a great expression level of this family. The plasma levels of miR-24-3p, miR-16-5p, miR-185-5p, and miR-451a were upregulated during noise exposures, and increased levels of miR-21 have been found in vestibular schwannomas and human cholesteatoma. In addition, upregulation of pro-apoptotic miRNAs and downregulation of miRNAs which promote differentiation and proliferation in age-related degeneration of the organ of Corti may potentially serve as a helpful biomarker for the early detection of age-related hearing loss. This knowledge represents miRNAs as promising diagnostic and therapeutic tools in the near future.

Abstract
BACKGROUND Enhanced sarcoplasmic reticulum Ca(2+)-leak via ryanodine receptor type-2 (RyR2) contributes to the pathogenesis of atrial fibrillation (AF). Recent studies have shown that the level of RyR2 protein is elevated in atria of patients with paroxysmal AF, suggesting that microRNA-mediated post-transcriptional regulation of RyR2 might be an underlying mechanism. Bioinformatic analysis suggests that miR-106b and miR-93, members of the miR-106b-25 cluster, could bind to RyR2-3'-untranslated region and suppress its translation. Thus, we tested the hypothesis that loss of the miR-106b-25 cluster promotes AF via enhanced RyR2-mediated sarcoplasmic reticulum Ca(2+)-leak. METHODS AND RESULTS Quantitative real-time polymerase chain reaction showed that the levels of mature miR-106b, miR-93, and miR-25 were lower in atria of patients with paroxysmal AF when compared with patients in sinus rhythm. In vitro assay showed that miR-93 reduced RyR2-3'-untranslated region luciferase activity. Total RyR2 protein in atrial tissue of miR-106b-25(-/-) mice was increased by 42% when compared with wild-type littermates but still maintained a normal subcellular distribution. Ca(2+)-spark frequency and total sarcoplasmic reticulum Ca(2+)-leak were increased in atrial myocytes of miR-106b-25(-/-) mice. Telemetry ECG recordings revealed that miR-106b-25(-/-) mice exhibited more frequent atrial ectopy and were also more susceptible to pacing-induced AF than wild-type littermates. Increased sarcoplasmic reticulum Ca(2+)-release and AF susceptibility in miR-106b-25(-/-) mice were abolished by the RyR2 blocker K201. CONCLUSIONS These results suggest that miR-106b-25 cluster-mediated post-transcriptional regulation of RyR2 is a potential molecular mechanism involved in paroxysmal AF pathogenesis. As such, the miR-106b-25 cluster could be a novel gene-therapy target in AF associated with enhanced RyR2 expression.
