Investigation of New Morpholino Oligomers to Increase Survival Motor Neuron Protein Levels in Spinal Muscular Atrophy
Spinal muscular atrophy (SMA) is an autosomal-recessive childhood motor neuron disease and the main genetic cause of infant mortality. SMA is caused by deletions or mutations in the survival motor neuron 1 (SMN1) gene, which results in SMN protein deficiency. Only one approved drug has recently become available and allows for the correction of aberrant splicing of the paralogous SMN2 gene by an...
متن کاملSurvival motor neuron protein modulates neuron-specific apoptosis.
Spinal muscular atrophy (SMA) is attributed to mutations in the SMN1 gene, leading to loss of spinal cord motor neurons. The neurotropic Sindbis virus vector system was used to investigate a role for the survival motor neuron (SMN) protein in regulating neuronal apoptosis. Here we show that SMN protects primary neurons and differentiated neuron-like stem cells, but not cultured cell lines from ...
متن کاملThe survival motor neuron protein in spinal muscular atrophy.
The 38 kDa survival motor neuron (SMN) protein is encoded by two ubiquitously expressed genes: telomeric SMN (SMN(T)) and centromeric SMN (SMN(C)). Mutations in SMN(T), but not SMN(C), cause proximal spinal muscular atrophy (SMA), an autosomal recessive disorder that results in loss of motor neurons. SMN is found in the cytoplasm and nucleus. The nuclear form is located in structures termed gem...
متن کاملThe survival motor neuron protein of Schizosacharomyces pombe. Conservation of survival motor neuron interaction domains in divergent organisms.
Spinal muscular atrophy is a common often lethal neurodegenerative disease resulting from deletions or mutations in the survival motor neuron gene (SMN). SMN is ubiquitously expressed in metazoan cells and plays a role in small nuclear ribonucleoprotein assembly and pre-mRNA splicing. Here we characterize the Schizosacharomyces pombe orthologue of SMN (yeast SMN (ySMN)). We report that the ySMN...
متن کاملSurvival motor neuron: motor neuron insurance for a whole lifespan?
The SMN (survival motor neuron) gene plays an important role in ontogenesis and its dysfunction leads to immatu-rity of skeletal muscles and motor neurons in the spinal cord. As a result of SMN mutations the affected cells die and clinical symptoms of spinal muscular atrophy (SMA) develop. Physiologically, SMN together with gemins is part of a multiprotein complex of particular importance to mo...
