Duchenne muscular dystrophy (DMD) is a fatal, X-linked neuromuscular disease that affects 1 boy in 3500 to 5000 boys. The golden retriever muscular dystrophy dog is the best clinically relevant DMD animal model. Here, we used a high-thoughput miRNA sequencing screening for identification of candidate serum miRNA biomarkers in golden retriever muscular dystrophy dogs. We confirmed the dysregulation of the previously described muscle miRNAs, miR-1, miR-133, miR-206, and miR-378, and identified a new candidate muscle miRNA, miR-95. We identified two other classes of dysregulated serum miRNAs in muscular dystrophy: miRNAs belonging to the largest known miRNA cluster that resides in the imprinting DLK1-DIO3 genomic region and miRNAs associated with cardiac disease, including miR-208a, miR-208b, and miR-499. No simple correlation was identified between serum levels of cardiac miRNAs and cardiac functional parameters in golden retriever muscular dystrophy dogs. Finally, we confirmed a dysregulation of miR-95, miR-208a, miR-208b, miR-499, and miR-539 in a small cohort of DMD patients. Given the interspecies conservation of miRNAs and preliminary data in DMD patients, these newly identified dysregulated miRNAs are strong candidate biomarkers for DMD patients.
