title: Age-related changes in dystrophin-glycoprotein complex and in utrophin are not correlated with intrinsic laryngeal muscles protection in mdx mice.
abstract: In this study we investigate whether dystrophic intrinsic laryngeal muscles (ILM) from aged mdx mice show alterations in dystrophin-glycoprotein complex (DGC) components.Immunofluorescence and immunoblotting analyses of beta-sarcoglycan, beta-dystroglycan, and utrophin showed that aged ILM had a similar pattern of changes in aged affected muscles (diaphragm and limb), suggesting that aging leads to changes in utrophin and DGC proteins in dystrophic ILM that cannot be correlated with their protection from dystrophic change.
