Diversification of mammalian spinal motor neurons into hundreds of subtypes is critical for the maintenance of body posture and coordination of complex movements.

Selective vulnerability of spinal and cortical motor neuron subpopulations in delta7 SMA mice. [PDF]
Loss of the survival motor neuron gene (SMN1) is responsible for spinal muscular atrophy (SMA), the most common inherited cause of infant mortality. Even though the SMA phenotype is traditionally considered as related to spinal motor neuron loss, it ...

Viral delivery of antioxidant genes as a therapeutic strategy in experimental models of amyotrophic lateral sclerosis. [PDF]
Amyotrophic lateral sclerosis (ALS) is a progressive neurodegenerative disorder with no effective treatment to date. Despite its multi-factorial aetiology, oxidative stress is hypothesized to be one of the key pathogenic mechanisms.

Abnormal motoneuron migration, differentiation, and axon outgrowth in spinal muscular atrophy [PDF]
The role of heterotopic (migratory) motoneurons (HMN) in the pathogenesis of spinal muscular atrophy (SMA) is still controversial. We examined the occurrence and amount of HMN in spinal cord tissue from eight children with SMA (six with SMA-I and two ...

The survival motor neuron protein in spinal muscular atrophy [PDF]
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 survival motor neuron protein of Schizosacharomyces pombe. Conservation of survival motor neuron interaction domains in divergent organisms. [PDF]
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 (

Drosophila Neurotrophins Reveal a Common Mechanism for Nervous System Formation [PDF]
Neurotrophic interactions occur in Drosophila, but to date, no neurotrophic factor had been found. Neurotrophins are the main vertebrate secreted signalling molecules that link nervous system structure and function: they regulate neuronal survival ...

SAM68 is a physiological regulator of SMN2 splicing in spinal muscular atrophy [PDF]
Spinal muscular atrophy (SMA) is a neurodegenerative disease caused by loss of motor neurons in patients with null mutations in the SMN1 gene. The almost identical SMN2 gene is unable to compensate for this deficiency because of the skipping of exon 7 ...

Restoration of SMN in Schwann cells reverses myelination defects and improves neuromuscular function in spinal muscular atrophy [PDF]
Spinal muscular atrophy (SMA) is a neuromuscular disease caused by low levels of SMN protein, primarily affecting lower motor neurons. Recent evidence from SMA and related conditions suggests that glial cells can influence disease severity.

Altered Metabolic Profiles Associate with Toxicity in SOD1G93A Astrocyte-Neuron Co-Cultures
Non-cell autonomous processes involving astrocytes have been shown to contribute to motor neuron degeneration in amyotrophic lateral sclerosis. Mutant superoxide dismutase 1 (SOD1G93A) expression in astrocytes is selectively toxic to motor neurons in co ...
