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.
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.
Project description: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.
Project description:Antisense oligonuleotides targeting human AR (AR-ASO) or Rest4 (Rest4-ASO) are intracerebroventriculary injected to AR-97Q mice at postnatal day 1 (P1). Gene expression profiles were analysed in the spinal cord of WT and AR-97Q mice at P7 and 13 weeks of age.
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.
Project description:Transcriptional changes of AR-97Q cells and AR-17Q cells were compared. RNA-seq gene expression analysis revealed that differentially expressed genes were associated with regulation of signaling and regulation of cell communication as biological process, and membrane was most relevant to the genes as cellular component.
