Among the known causative genes of familial ALS, SOD1mutation is one of the most common. It encodes for the ubiquitous detoxifying copper/zinc binding SOD1 enzyme, whose mutations selectively cause motor neuron death, although the mechanisms are not as yet clear. What is known is that mutant-mediated toxicity is not caused by loss of its detoxifying activity but by a gain-of-function. In order to better understand the pathogenic mechanisms of SOD1 mutation, a human induced pluripotent stem cell (hiPSC) line was generated from the somatic cells of a female patient carrying a missense variation in SOD1 (L145F).
在已知的家族性肌萎缩侧索硬化症(ALS)致病基因中,超氧化物歧化酶1(SOD1)突变是最常见的突变之一。它编码普遍存在的解毒铜/锌结合SOD1酶,尽管其机制尚不清楚,但该酶的突变会选择性地导致运动神经元死亡。已知突变介导的毒性不是由其解毒活性丧失引起的,而是由功能获得引起的。为了更好地理解SOD1突变的致病机制,从一名携带SOD1错义变异(L145F)的女性患者的体细胞中生成了一条人诱导多能干细胞(hiPSC)系。
