The purpose of this research program is to investigate the mechanisms of hereditary neurological diseases, with the ultimate intent of developing effective treatments for these disorders. Recently, the research has focused on three specific neuromuscular diseases: autosomal recessive spinal muscular atrophy (SMA) due to deficiency of the protein SMN, X-linked spinal and bulbar muscular atrophy (SBMA) due to polyglutamine expansion in the androgen receptor, and myofibrillar myopathy caused by mutations in ZASP. Specific research accomplishments in the past year include the following: (1) evaluation of the effects of proteasome inhibitor treatment in a mouse model of SMA, (2) characterization of the effects of IGF-1 in an animal model of SBMA,(3) identification of interacting proteins for wild type and mutant ZASP and developing animal models with ZASP mutation.

该研究计划的目的是调查遗传性神经系统疾病的机制，最终目的是为这些疾病开发有效的治疗方法。最近，研究集中在三种特定的神经肌肉疾病：由于蛋白SMN缺乏引起的常染色体隐性脊髓性肌萎缩症（SMA），由于雄激素受体中的多聚谷氨酰胺扩增引起的X连锁脊髓和延髓肌萎缩症（SBMA），以及由ZASP突变引起的肌原纤维性肌病。过去一年的具体研究成果包括：（1）在SMA小鼠模型中评估蛋白酶体抑制剂治疗的效果，（2）在SBMA动物模型中表征IGF-1的作用，（3）鉴定野生型和突变型ZASP的相互作用蛋白，并开发ZASP突变的动物模型。
