(Submitter supplied) Microarray analysis has been applied to the study of ALS in order to investigate gene expression in whole spinal cord homogenates of SOD1 G93A mice and human ALS cases, although the massive presence of glial cells and inflammatory factors has made it difficult to define which gene expression changes were motor neuron specific. Recently, laser capture microdissection (LCM), combined with microarray analysis, has allowed the identification of motor neuron specific changes in gene expression in human ALS cases. more...

Analysis of motor neurons of 60, 90, and 120 day old SOD1 G93A transgenics, a model for familial amyotrophic lateral sclerosis (ALS). ALS is an adult-onset neurodegenerative disease characterized by degeneration of upper and lower motor neurons. Results provide insight into the pathogenesis of ALS.

(Submitter supplied) Familial amyotrophic lateral sclerosis (ALS) represents about 10% of ALS cases. In about 20% of familial ALS patients, a mutation in superoxide dismutase-1 (SOD1) can be found. The ubiquitous SOD1 protein converts superoxide radical anions to oxygen and hydrogen peroxide. Patients with familial ALS caused by mutations in SOD1 can show comorbidity with frontotemporal dementia and develop cognitive impairment, including apathy, inattention, verbal deficits, and hypersexuality. more...

(Submitter supplied) To investigate the role of motor neuron autophagy in ALS, we generated mice in which the critical autophagy gene Atg7 was specifically disrupted in motor neurons (Atg7 cKO). We also bred these mice to the SOD1G93A mouse model of ALS. Then we performed RNA sequencing on lumbar spinal cords from these mice to determine how motor neuron autophagy inhibition altered gene expression.

(Submitter supplied) Gene expression analyses through cDNA microarray of fifteen gastrocnemius muscles from transgenic and wild-type SOD1G93A mouse model by the ages of 40 and 80 days old were performed. We used a customized cDNA array containing the cDNA platform comprised of 2352 spots, 326 of them orthologous to mouse, 1384 additional human cDNA sequences, 496 negative controls (DMSO) and 48 positive controls (the Q gene from λ-phage). more...

(Submitter supplied) Spinal motor axons traverse large distances to innervate target muscle, and thus require local control of cellular events for proper functioning of the distal axon. To interrogate axon-specific processes we developed Axon-seq, a refined method incorporating microfluidic devices and stringent bioinformatic quality controls. Axon-seq demonstrates improved sensitivity and accuracy in whole-transcriptome sequencing of axons compared to previously published studies. more...

(Submitter supplied) The aim of the present study is to combine LCM and microarray analysis to study how astrocytes in the spinal cord of transgenic SOD1 G93A mice and their non-transgenic (NTg) littermates respond to stimuli determined by the presence of the human mutant protein throughout the evolution of the disease by looking at the symptomatic and late-stage disease time points.
