The muscular dystrophies (MDs) are genetic disorders of muscle degeneration due to mutations in genes that encode a wide variety of proteins. Dysferlinopathy are characterized by the absence of dysferlin in skeletal muscle and an autosomal recessive mode of inheritance. Both histological and ultrastructural pathology have been well established in dysferlinopathy patients and dysferlin-deficient animal models. To our knowledge the effect of antioxidant supplementation on this level has not been described previously. This article therefore focuses on the histopathology to reveal the effect of antioxidant supplementation. The study aimed to determine, at cellular level, the histopathological changes in the SJL/J mouse model following a 90 day trial with antioxidant supplementation. Markedly reduced inflammatory insult in the more affected quadriceps muscles of animals treated with high doses of CoQ10 and a combination of resveratrol/CoQ10 were observed. The outcome provides evidence that high doses of antioxidant supplementation resulted in decreased dystrophic markers and enhanced tissue integrity at cellular level.
