摘要
The DYT1 gene containing a trinucleotide deletion (Delta GAG) is linked to early-onset dystonia, a neurological movement disorder of involuntary muscle contractions. To understand DYT1's contribution to dystonia, we produced and analyzed Dyt1 knockdown (KD) mice that expressed a reduced level of torsinA protein encoded by Dyt1. Knockdown mice exhibited deficits in motor control and a decreased trend in dopamine with a significant reduction in 3,4-dihydroxyphenylacetic acid. These alterations are similar to those displayed by previously reported Dyt1 Delta GAG knockin heterozygous mice, suggesting that the partial loss of torsinA function contributes to the pathology of the disease.
