Protein aggregate myopathies.
Protein aggregate myopathies (PAMs) based on the morphologic phenomenon of aggregation of proteins within muscle fibers may occur in children (selenoproteinopathies, actinopathies, and myosinopathies) or adults (certain myofibrillar myopathies and myosinopathies). They may be mutation related, which includes virtually all childhood forms but certain other forms as well, or sporadic, which are l...
متن کاملTAR DNA-Binding protein 43 accumulation in protein aggregate myopathies.
Protein aggregate myopathies, including myofibrillar myopathies and sporadic inclusion body myositis (sIBM), are characterized by abnormal protein aggregates composed of various muscular and ectopic proteins. Previous studies have shown the crucial role ofdysregulated transcription factors such as neuron-restrictive silencerfactor in the expression of aberrant proteins in myotilinopathies. Here...
متن کاملProtein aggregation in inclusion body myositis, a sporadic form among protein aggregate myopathies, and in myofibrillar myopathies--a comparative study.
UNLABELLED Protein aggregation has been identified in muscle fibres and, thus, in certain neuromuscular disorders. There are certain similarities between IBM and DRM: midlife or late-onset clinical symptoms, apparently of both sporadic and genetic background, morphologically autophagocytosis by vacuole formation, which is frequent in IBM though rare in DRM, and presence of tubulofilamentous agg...
متن کاملImmunolocalization of protein-bound 3-nitrotyrosine in inflammatory myopathies.
3-nitrotyrosine (3NT) is regarded as a "footprint" of nitric oxide generation. The study aimed at documenting the presence and distribution of 3-nitrotyrosine (3NT) in muscle tissue samples from patients with idiopathic inflammatory myopathies (IIM) as well as from those with non-inflammatory myopathies to consider whether polymyositis (PM) and dermatomyositis (DM) could be distinguished based ...
متن کاملCongenital myopathies.
This review focuses on congenital myopathies, a distinct but markedly heterogeneous group of muscle disorders that present with muscle weakness and typically appear at birth or in infancy. These myopathies have characteristic histopathologic abnormalities on muscle biopsy, allowing a preliminary morphologic classification. Advances in molecular genetics have allowed a more rational classificati...
