Transcriptomic profiling of spinal and bulbar muscular atrophy cultured embryonic motor neurons

ABSTRACT: Spinal and bulbar muscular atrophy (SBMA), also known as Kennedy’s Disease, is a slowly progressive adult-onset neuromuscular disease which results from a polyglutamine (polyQ) encoding CAG repeat expansion within the androgen receptor gene (AR). Despite the ubiquitous expression of the androgen receptor, it is unclear why motor neurons selectively degenerate and there are no effective treatments or disease modifying therapies for this debilitating disease. In order to identify potential therapeutic targets, we set out to establish the genes and molecular pathways involved in early motor neuron dysfunction in SBMA. We therefore undertook global transcriptomic profiling of cultured primary embryonic motor neurons from the spinal cord of AR100 mice, which model SBMA.. Four biological replicate samples were used for genome wide analysis using Affymetrix 430 v2.0 mouse arrays. Data was normalised using therobust multichip average (RMA) algorithm.

Spinal and bulbar muscular atrophy (SBMA) results from a CAG repeat expansion within the androgen receptor gene (AR). It is unclear why motor neurons selectively degenerate and there are currently no treatments for this debilitating disease. To uncover the causative genes and pathways involved in motor neuron dysfunction, we undertook transcriptomic profiling of primary embryonic motor neurons from SBMA mice. We show that transcriptional dysregulation occurs early during development in SBMA moto ...[more]

Project description:FUS/TLS is an RNA/DNA-binding protein associated with neurodegenerative diseases including amyotrophic lateral sclerosis and frontotemporal lobar degeneration. Previously, we found that a prion-like domain in the N-terminus of FUS/TLS mediates co-aggregation between FUS/TLS and mutant huntingtin, the gene product of Huntington's disease (HD). Here, we show that heterozygous knockout of FUS/TLS worsened the phenotypes of model mice of Huntington's disease (HD) but not spinal and bulbar muscular atrophy (SBMA). This difference was correlated with the degree of pathological association between disease proteins and FUS/TLS. Co-aggregation between FUS/TLS and mutant huntingtin resulted in the depletion of free FUS/TLS protein in HD mice that was detected as a monomer in SDS-PAGE analysis. Recently, we found that FUS/TLS paralogs, TAF15 and EWS, were up-regulated in homozygous FUS/TLS knockout mice. These two proteins were up-regulated in both HD and FUS/TLS heterozygote mice, and were further elevated in HD-TLS+/- double mutant mice, consistent with the functional impairment of FUS/TLS. These results suggest that FUS/TLS sequestration by co-aggregation is a rate-limiting factor of disease phenotypes of HD and that inclusions may have an adverse aspect, rather than being simply benign or protective. In addition, our results highlight inclusions as repositories of potential modifiers of neurodegeneration. Gene expression profiles were analyzed to examine the effects of FUS/TLS heterozygosity in mouse with or without the transgene of mutant androgen receptor. Overall design: To examine the effect of FUS/TLS heterozygosity on the transcriptome of spinal and bulbar muscular atrophy (SBMA) model mice, we crossed FUS/TLS heterozygous knockout mice with SBMA model mice. We extracted total RNA from the spinal cord of these mice at 8 weeks and used for a microarray analysis. The samples are SBMA transgenic mice with FUS/TLS heterozygosity (SBMA_TLS+/-), SBMA mice with normal FUS/TLS (SBMA_TLS+/+), non-SBMA-transgenic mice with FUS/TLS heterozygosity (NT_TLS+/-), and non-SBMA-transgenic mice with normal FUS/TLS (NT_TLS+/+).

Project description:Emerging evidence implicates transcriptional dyseregulation within skeletal muscle in the pathogenesis of Kennedy disease/spinal bulbar muscular atrophy (KD/SBMA). We therefore broadly characterized gene expression in skeletal muscle of three independently generated mouse models of this disorder. The mouse models included a polyglutamine expanded (polyQ) AR knock-in model (AR113Q KI), a polyQ AR transgenic model (AR97Q Tg), and a transgenic mouse which overexpresses wild type AR solely in muscle (HSA-AR Tg). We performed microarray analysis of lower hindlimb muscles taken from these three models using high density oligonucleotide arrays. Changes in gene expression relative to wild type controls were evaluated separately in each strain. We validated our results using quantitative RT-PCR. Patterns of gene expression that are common to all lines and unique to each are described. When considered globally, the degree of overlap between the three models is approximately equivalent, and several patterns of gene expression relevant to the disease process were observed. Notably, patterns of gene expression typical of loss of AR function were observed in all three models, as were alterations in genes involved in cell adhesion, energy balance, Huntington’s disease, muscle atrophy and myogenesis. By comparing patterns of gene expression in three independent models of KD/SBMA, we have been able to identify candidate genes that might mediate the core myogenic features of KD/SBMA. Keywords: Gene expression in transgenic mice and disease state analysis Overall design: We used microarray (38.5K oligo mouse array, which contain 35,302 of 70mer oligonucleotide probes largely derived from constitutively expressed exons and 3,482 of controls) to analyze gene expression in limb muscles of transgenic mice. Three mouse models of KD/SBMA were used: HSA-AR, AR113Q knock-in and AR97Q. HSA-AR transgenic male mice (n=5) and their WT brothers (n=8, all mice were 110-130 days of age) were used in this experiment. ARQ113-Knock In males (n=3, 3-4 months of age), and transgenic AR97Q males and WT brothers (n= 6 of each) were used in this study. For both HSA-AR and AR113Q samples, the log2 ratio of experimental samples (Cy5) and reference RNA(Cy3) was obtained, and log2 ratios from mutant samples were then subtracted from log2 ratios from WT controls. AR97Q males (Cy5) were simply compared with their WT brothers (Cy3) using a log2 ratio, rather than being first compared with reference RNA.
