Abstract
Antioxidants have a great potential as adjuvant therapeutics in patients with Duchenne muscular dystrophy, although systematic comparisons at pre-clinical level are limited. The present study is a head-to-head assessment, in the exercised mdx mouse model of DMD, of natural compounds, resveratrol and apocynin, and of the amino acid taurine, in comparison with the gold standard α-methyl prednisolone (PDN). The rationale was to target the overproduction of reactive oxygen species (ROS) via disease-related pathways that are worsened by mechanical-metabolic impairment such as inflammation and over-activity of NADPH oxidase (NOX) (taurine and apocynin, respectively) or the failing ROS detoxification mechanisms via sirtuin-1 (SIRT1)-peroxisome proliferator-activated receptor γ coactivator 1α (PGC-1α) (resveratrol). Resveratrol (100mg/kg i.p. 5days/week), apocynin (38mg/kg/day per os), taurine (1g/kg/day per os), and PDN (1mg/kg i.p., 5days/week) were administered for 4-5 weeks to mdx mice in parallel with a standard protocol of treadmill exercise and the outcome was evaluated with a multidisciplinary approach in vivo and ex vivo on pathology-related end-points and biomarkers of oxidative stress. Resveratrol≥taurine>apocynin enhanced in vivo mouse force similarly to PDN. All the compounds reduced the production of superoxide anion, assessed by dihydroethidium staining, with apocynin being as effective as PDN, and ameliorated electrophysiological biomarkers of oxidative stress. Resveratrol also significantly reduced plasma levels of creatine kinase and lactate dehydrogenase. Force of isolated muscles was little ameliorated. However, the three compounds improved histopathology of gastrocnemius muscle more than PDN. Taurine>apocynin>PDN significantly decreased activated NF-kB positive myofibers. Thus, compounds targeting NOX-ROS or SIRT1/PGC-1α pathways differently modulate clinically relevant DMD-related endpoints according to their mechanism of action. With the caution needed in translational research, the results show that the parallel assessment can help the identification of best adjuvant therapies.
