Here, we treated <jats:italic>mdx<\/jats:italic> mice with various doses of resveratrol (0.04, 0.4, and 4\u2009g\/kg food) for 56 weeks and examined the effects on serum creatine kinase levels and physical activities. Because resveratrol promotes autophagy, we also investigated whether autophagy including mitochondrial autophagy (mitophagy) is involved in resveratrol\u2019s effects. Autophagy\/mitophagy\u2010related genes and autophagic flux were downregulated in the muscle of <jats:italic>mdx<\/jats:italic> mice, and these phenomena were reversed by resveratrol with significant ROS reduction. Resveratrol at 4\u2009g\/kg food reduced the number of immature myofibers containing central nuclei and fine fibers\u2009&lt;\u2009400\u2009<jats:italic>\u03bc<\/jats:italic>m<jats:sup>2<\/jats:sup> and increased that of thicker myofibers in the quadriceps, suggesting that resveratrol decreased myofiber wasting and promoted muscular maturation. Accordingly, resveratrol at 0.4\u2009g\/kg food reduced the creatine kinase levels to one\u2010third of those in untreated <jats:italic>mdx<\/jats:italic> mice and significantly increased the animals\u2019 physical activities. In C2C12 myoblast cells, resveratrol promoted mitophagy and eliminated mitochondria containing high superoxide levels. The clearance of damaged mitochondria and ROS reduction by resveratrol was completely suppressed by an autophagy inhibitor (chloroquine) and by knocking down <jats:italic>Atg5<\/jats:italic> or <jats:italic>Pink1<\/jats:italic>, essential genes for autophagy and mitophagy, respectively. Thus, resveratrol is a potential therapeutic agent for DMD, and the clearance of damaged mitochondria probably contributes to its action.<\/jats:p>","DOI":"10.1155\/2018\/9179270","type":"journal-article","created":{"date-parts":[[2018,10,30]],"date-time":"2018-10-30T02:19:31Z","timestamp":1540865971000},"update-policy":"https:\/\/doi.org\/10.1002\/crossmark_policy","source":"Crossref","is-referenced-by-count":110,"title":["Resveratrol
