项目摘要

DESCRIPTION (provided by applicant): Spinal muscular atrophy (SMA) is the most common inherited cause of death in infants and young children. SMA is caused by the deletion or mutation in the survival of motor neuron 1 (SMN1) gene, leading to a deficiency of the ubiquitously expressed SMN protein. Currently, there is no effective treatment option available for SMA. Evidence from studies in humans and rodents suggests that increasing SMN protein levels in the central nervous system is sufficient to ameliorate the disease phenotype and prolong survival. To identify protective modifiers of SMN protein levels we performed a genome-wide RNAi screen. Genes we identified in this screen will allow us to investigate genetic modifiers and molecular pathways that regulate SMN protein levels. These targets and pathways should provide novel avenues for therapeutic development for the treatment of SMA.

描述（由适用提供）：脊柱肌肉萎缩（SMA）是婴儿和幼儿中最常见的遗传死亡原因。 SMA是由运动神经元1（SMN1）基因存活中的缺失或突变引起的，导致无处不在表达的SMN蛋白的缺乏。当前，SMA尚无有效的治疗选择。来自人类和啮齿动物的研究的证据表明，中枢神经系统中SMN蛋白水平的提高足以改善疾病表型并延长生存率。为了鉴定SMN蛋白水平的受保护的修饰符，我们进行了全基因组RNAi筛选。我们在此屏幕上鉴定的基因将使我们能够研究调节SMN蛋白水平的遗传修饰剂和分子途径。这些目标和途径应为治疗SMA的治疗发展提供新的途径。
