Single-nucleus RNA-seq results of AR-97Q and AR-24Q mice at 8 weeks of age.

ABSTRACT: To understand the early pathogenesis of motor neuron degeneration in spinal and bulbar muscular atrophy (SBMA), we conducted single-nucleus RNA-seq (snRNA-seq) on the spinal cords of AR-97Q and AR-24Q mice at 8 weeks of age. REST target genes were up-regulated in motor neurons of AR-97Q mice.

RNA-Seq results of a neuronal cell model of SBMA, AR-97Q cells, compared to AR-24Q cells

Project description:Spinal and bulbar muscular atrophy (SBMA) is a neuromuscular disorder caused by a polyglutamine expansion in the androgen receptor (AR). Transcriptional changes were compared between a muscle cell model of SBMA (AR-97Q cells) and a control model (AR-24Q cells). RNA-seq gene expression analysis revealed that differentially expressed genes were associated with upregulation of transforming growth factor β (TGFβ) signaling, mitogen-activated protein kinase (MAPK), tumor necrosis factor (TNF) signaling, calcium signaling, and NFκB signaling.

Single cell RNA-Seq result of spinal cord of AR-97Q mice and AR-24Q mice at 6 weeks

Project description:To understand the early pathogenesis of SBMA and to systematically assess the role of different cells in the spinal cord of SBMA, we conducted snRNA-seq on the spinal cord of AR-97Q and AR-24Q mice at 6 weeks. The genes related to ion channel and synapse function were up-regulated in oligodendrocytes of AR-97Q mice.

RNA-seq of sipinal cord of WT, AR-24Q, AR-97Q, testosterone-treated AR-97Q mice, Scramble-ASO-treated AR-97Q mice, and Rest4-ASO #3-treated AR-97Q mice at P7

Project description:Testosterone (20 mg) was subcutaneously adminstered to AR-97Q mice at postnatal day 1 (P1). Scramble-ASO and Rest4-ASO #3 were intracerebroventriculary administred to AR-97Q mice at P1.Gene expression profiles were analysed in the spinal cord of WT, AR-24Q, AR-97Q, testosterone-treated AR-97Q mice, Scramble-ASO-treated AR-97Q mice, and Rest4-ASO #3-treated AR-97Q mice at P7.

The gene expression analysis of the spinal cord of SBMA (Spinal Bulbar Muscular Atrophy) model mice

Project description:To identify the gene expression changes that are specific to SBMA, we prepared total mRNA samples from the spinal cords of transgenic mice carrying a full-length human AR with 97 CAGs (AR-97Q), transgenic mice bearing a wild-type allele of AR with 24 CAGs (AR-24Q), and the wild-type littermates of the AR-97Q mice (C57BL/6). We used AR-97Q (Line #7-8) male mice because they show progressive muscular atrophy and weakness as well as SBMA-like pathology such as the accumulation of the pathogenic androgen receptor in the nucleus of motor neurons. Using microarray analysis, we identified the genes with significantly altered expression among the three types of mice. For each group, we examined the male mice at 7-9, 10-12, and 13-15 weeks of age. These stages were chosen because the AR-97Q mice are generally asymptomatic at 7-9 weeks of age (before-onset stage), present with mild motor impairment at 10-12 weeks (early stage), and are severely weakened with profound muscle atrophy at 13-15 weeks (advanced stage). RNA from the total spinal cord, excluding the dorsal root ganglia, was isolated from three mice of each genotype at each stage. For wild-type, pooled sample for three mice were used in each stage.

The gene expression analysis of the spinal cord and skeletal muscle of SBMA (Spinal Bulbar Muscular Atrophy) model mice with or without pioglitazone (PG) treatment

Project description:To identify the gene expression changes by administering PG to SBMA model mice, we prepared total RNA samples from the spinal cords and skeletal muscles of transgenic mice carrying a full-length human AR with 97 CAGs (AR-97Q) that were treated with or without PG. We used AR-97Q (Line #7-8) male mice because they show progressive muscular atrophy and weakness as well as SBMA-like pathology such as the accumulation of the pathogenic androgen receptor in the nucleus of motor neurons. Using microarray analysis, we identified the genes with significantly altered expression of AR-97Q mice by PG treatment. For non-treated and PG-treated groups, we examined the male mice at 13 weeks of age. RNA from the total spinal cord and skeletal muscle was isolated from three mice of each group.

Single cell RNA-Seq result of spinal cord of AR-97Q mice and wild-type mice at four disease stages

Project description:To understand the early pathogenesis of SBMA and to systematically assess the role of different cells in the spinal cord of SBMA, we conducted snRNA-seq on the spinal cord of AR-97Q mice at different stages of the disease. The genes related to ion channel and synapse function were up-regulated in oligodendrocytes in early stages of SBMA although they were down-regulated at the advanced stage.

Mechanism of Mitochondrial Dysfunction in Spinal and Bulbar Muscular Atrophy [AR ChIP-seq]

Project description:Spinal and bulbar muscular atrophy (SBMA) is a neuromuscular disorder caused by a polyglutamine expansion in the androgen receptor (AR). Previous studies have shown that transcriptional dysregulation and mitochondrial impairment occur in SBMA. We used gene-expression analysis and ChIP-sequencing to map transcriptional changes in SBMA induced pluripotent stem cell-derived motor neurons. The SBMA cells had decreased expression of genes encoding electron transport chain subunits and other metabolic proteins, associated with reduced histone acetylation which may be contributing to mitochondrial dysfunction. AR ChIP-sequencing results indicate that this is not a direct transcriptional effect of mutant AR on mitochondrial gene expression. Furthermore, we found decreased acetyl-CoA, and pyruvate supplementation to correct this deficiency improved mitochondrial function and SBMA motor neuron viability. We propose that epigenetic dysregulation of metabolic genes contributes to reduced mitochondrial ATP production. Our results show a molecular link between altered epigenetic regulation and mitochondrial metabolism that contributes to neurodegeneration.
