Transcription profiling of skeletal muscle from amyotrophic lateral sclerosis sod1(G86R) axotomized mice and control mice to monitor denervation-dependent gene expression in an Amyotrophic lateral sclerosis (ALS) mouse model

Amyotrophic lateral sclerosis (ALS) is a fatal adult-onset neuromuscular disorder characterized by the selective degeneration of upper and lower motor neurons, progressive muscle wasting and paralysis. To define the full set of alterations in gene expression in skeletal muscle during the course of the disease, we performed high-density oligonucleotide microarray analysis of gene expression in hind limb skeletal muscles of sod1(G86R) mice, one of the existing transgenic models of ALS. To monitor denervation-dependent gene expression, we determined the effects of short-term acute denervation on the muscle transcriptome after sciatic nerve axotomy.
