Abstract:Spinal and bulbar muscular atrophy (SBMA) is a neuromuscular disease caused by an expanded CAG repeat in the androgen receptor (AR) gene. To elucidate the cell type-specific temporal gene expression in SBMA, we performed single-nucleus RNA sequencing on the spinal cords of AR-97Q mice. Among all cell types, oligodendrocytes (OLs) had the highest number of differentially expressed genes before disease onset. Analysis of OL clusters suggested that pathways associated with cation channels and synaptic function we… Show more
