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.
