A previous study on mice with severe myositis has shown that increased expression of inflammatory miRNAs (miR-146a, miR-142-3p, miR-142-5p, and miR-455-5p) and targeted muscle dystrophins (miR-146a, miR-146b, miR-31, and miR-223) are regulated by NF-κB, and may be related to muscle injury, inflammation, and myasthenia (12). This evidence concerns the gene DMD and myositis disease.
