MetabolomicsFamily-based multi-omics reveal gut dysbiosis and circulatory metabolic disruption in amyotrophic lateral sclerosis

Background: Amyotrophic lateral sclerosis (ALS) is a fatal neurodegenerative disorder with unclear etiology and no effective cure. Accumulating evidence implicates gut microbiota dysbiosis and circulatory metabolic al-terations in ALS pathogenesis, potentially driving disease progression and seve...

TranscriptomicsTranscription profiling by array of post-mortem brain cortex from healthy control patients and amyotrophic lateral sclerosis patients that carry an expanded GGGGCC repeat mutation in the chromosome 9 open reading frame 72 (C9ORF72) gene
The purpose of this experiment was to compare differences in the transcript level between RNA samples collected from post-mortem motor cortex from healthy control patients and amyotrophic lateral sclerosis (ALS) patients that carry an expanded GGGGCC repeat mutation in the chromosome 9 open reading ...

ProteomicsMass spectrometric analysis of accumulated TDP-43 in amyotrophic lateral sclerosis brains
TDP-43 is the major disease-associated protein involved in the pathogenesis and progression of amyotrophic lateral sclerosis (ALS) and frontotemporal lobar degeneration with ubiquitin-positive inclusions linked to TDP-43 pathology (FTLD-TDP). Abnormal phosphorylation, truncation and cytoplasmic mis...

TranscriptomicsTranscriptome profile of C9ORF72 ALS fibroblast
The purpose of this experiment was to compare the differences in transcript levels between RNA samples collected from fibroblasts from healthy control patients, amyotrophic lateral sclerosis (ALS) patients carrying an expanded GGGGCC repeat mutation in the chromosome 9 open reading frame 72 gene and...

TranscriptomicsTranscription 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 t...

TranscriptomicsMuscle Gene Expression Is a Marker of Amyotrophic Lateral Sclerosis Severity
This study was designed to identify gene expression changes in skeletal muscle that could define reliably the degree of the severity of Amyotrophic lateral sclerosis (ALS). All samples were from human biopsies, either from healthy muscles or from muscle whose patients were clearly diagnosed as havin...

TranscriptomicsTranscription profiling of mouse model of amyotrophic lateral sclerosis (ALS) vs. wild type
mRNA expression in the spinal cords of the G93A-SOD1 familial ALS transgenic mouse model was compared to that in nontransgenic (Normal mouse) and transgenic mice expressing wild-type (WT)SOD1. Gene Ontology (GO)analysis was used to characterize differences in expression between G93A-SOD1 mouse and ...

TranscriptomicsSignaling pathways in skeletal muscle of Amyotrophic Lateral Sclerosis mouse model
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 mous...
