dc.description.resumoInflammation and oxidative stress occurs in muscle of Duchenne muscular dystrophy (DMD). The relationship between a panel of biomarkers and the DMD outcome is necessary to indicate of disease progression and response to rehabilitation programs. The aim was to analyze the connective tissue of muscle of Mdx mice and immunoexpression of MMP-2, MMP-9, and 8-OHdG, which signalizes oxidative stress related to DNA damage. Biceps brachii of male C57BL/10 and C57BL/10-Dmdmdx mice was submitted to Hematoxylin-Eosin, Sirius red and immunohistochemistry (MMP-2, MMP-9 and 8-OHdG) analysis. Mdx showed focal lesions with intense inflammation and fibrosis related to immunoexpression of MMP-2 and MMP-9, proving the hypothesis that these MMPs are linked to muscular tissue degeneration, which can be regenerated by their inhibition, improving the treatment of DMD carriers. Histopathological findings related to centralized nuclei increase were related to higher 8-OHdG immunomarked nuclei in Mdx, which signalizes oxidative stress associated with DNA damage provoked by DMD. Such result shows that the evaluation of 8-OHdG during the evolution of the disease could be a method to evaluate DMD disease progressionpt_BR
