Research Abstract

Spinal and bulbar muscular atrophy (SBMA) is an adult-onset motor neuron disease caused by the expansion of a trinucleotide CAG repeat in androgen receptor (AR).Recent studies suggest that synaptic dysfunction is an early molecular event in the pathogenesis of various neurodegenerative disorders. In this study, we investigated the synapse pathology in a mouse model of SBMA using immunohistochemistry and microarray analysis. Our results showed that neuromuscular junctions of SBMA mice are denervated at pre-symptomatic stage of the disease. The gene expression analysis identified down-regulated genes that have functions including ion binding.
