|Former Common name||B6D2-TgN(hAndR/CAGn)/97Q-7-8-917|
|ES Cell line|
|Strain development||The mice was generated by injecting AR-97Q construct into BDF1 fertilized eggs. The AR-97Q construct consisted of Chicken-actin promoter and human AR fragment harboring 97 CAGs. The founder Tg mice were backcrossed to C57BL/6J.|
|Strain description||Spinal and bulbar muscular atrophy (SBMA) is a polyglutamine disease with expansion of a CAG repeat in the androgen receptor (AR) gene. This transgenic mice serves as a SBMA model carrying a full-length AR containing 97 CAGs. The mice showed progressive muscular atrophy and weakness. The mice also showed diffuse nuclear staining and nuclear inclusions. These phenotypes were significant in male transgenic mice, and rescued by castration. Female transgenic mice showed much limited phenotypes which became more pronounced by administration of testosterone.|
|Colony maintenance||Survival and reproduction are reduced by extensive backcross to B6. Maintenance in the BDF1 background may improve the survival of the Tg.|
