| Research Abstract |
GNE was exclusively present in the cytoplasm of mutant GNE gene-transfected cells, which showed normal appearance. Specific 116 genes were detected in GNE-knocked down cells by oligonucleotide microarray. GNE may play a certain role in muscle fiber regeneration.The ubiquitin-proteasome proteolysis pathway as well as lysosomal-proteolysis pathway may mediate the muscle fiber destraction in rimmed vacuolar myopathy such as distal myopathy with rimmed vacuoles and chloroquine-indeced myopathy. IGF-1 treatment may suppress the overdevelopment of rimmed vacuoles in those myopathies.
