The interleukin-6 (IL-6) family of cytokines is thought to be involved in the development and regeneration of peripheral nerves; however, their roles in myelination remain unclear. In this study, we examined the effects of IL-6 on the expression of genes for compact myelin proteins using Schwann cell cultures prepared by multiple explantation of adult rat sciatic nerves. In semi-quantitative re...
Mutations found in the two major glycosylated transmembrane proteins of the PNS myelin, the peripheral myelin protein zero (P0) and peripheral myelin protein 22 (PMP22), have been independently associated with the most common hereditary demyelinating peripheral neuropathies. Genotype-phenotype correlations in humans and transgenic animals have provided functional evidence that P0 and PMP22 are ...
A European collaboration on Charcot-Marie-Tooth type 1 (CMT1) disease and hereditary neuropathy with liability to pressure palsies (HNPP) was established to estimate the duplication and deletion frequency, respectively, on chromosome 17p11.2 and to make an inventory of mutations in the myelin genes, peripheral myelin protein 22 (PMP22), myelin protein zero (MPZ) and connexin 32 (Cx32) located o...
BACKGROUND Sporadic and sometimes contradictory studies have indicated changes in satellite cell behaviour associated with the progressive nature of human Duchenne muscular dystrophy (DMD). Satellite cell proliferation and number are reportedly altered in DMD and the mdx mouse model. We recently found that satellite cells in MSVski transgenic mice, a muscle hypertrophy model showing progressive...
charcot-marie-tooth (cmt) is the commonest neurogenetic disorder with phenotypic and genotyping heterogeneity. cmt1a encompasses approximately 60% of all types of cmt and has ad inheritance. cmt1a maps to chromosome17 p11.2 and is majorly caused by 1.5 mb dna duplication that includes the peripheral protein 22 (pmp) genes. the severity, onset and progression of cmt1a vary markedly within and be...
RATIONALE Hereditary neuropathy with liability to pressure palsy (HNPP) is an episodic, multifocal neuropathy, with a typical clinical presentation of recurrent transient pressure palsies, which is induced by a PMP22 deletion. Another neuropathy caused by a PMP22 duplication is Charcot-Marie-Tooth disease type 1A (CMT1A). PMP22 is a gene coding a protein called peripheral myelin protein 22 (PMP...
Charcot-Marie-Tooth disease type 1A (CMT1A) is caused by duplication of peripheral myelin protein 22 (PMP22) and is the most common hereditary peripheral neuropathy. CMT1A is characterized by demyelination and axonal loss, which underlie slowed motor nerve conduction velocity (MNCV) and reduced compound muscle action potentials (CMAP) in patients. There is currently no known treatment for this ...
Osteosarcoma is the most common primary malignancy of bone. The tumours are characterized by high genomic instability, including the occurrence of multiple regions of amplifications and deletions. Chromosome region 17p11.2-p12 is amplified in about 25% of cases. In previous studies, COPS3 and PMP22 have been identified as candidate oncogenes in this region. Considering the complexity and variat...
