卷曲螺旋-螺旋-卷曲螺旋-螺旋结构域10(CHCHD 10)的突变已在患有各种退行性疾病的患者中鉴定,所述退行性疾病包括线粒体肌病、Jokela型脊髓性肌萎缩症、额颞叶痴呆和/或肌萎缩侧索硬化(ALS)。CHCHD 10相关的趋异性疾病的致病机制在很大程度上仍然未知。在这里,我们表明,与CHCHD 10-WT转基因小鼠相比,过表达ALS相关的CHCHD 10 p.R15L突变的转基因小鼠导致寿命缩短。表型的发生和严重程度与转基因拷贝数相关。中枢神经系统(CNS)、骨骼肌和心脏病理学在CHCHD 10-R15 L转基因小鼠中明显。尽管存在病理学,但CHCHD 10-R15 L转基因小鼠在运动行为任务中表现出与对照小鼠相同的能力,直到非常接近死亡。尽管未观察到麻痹,但这些模型提供了对CHCHD 10的多效性性质的深入了解,并表明CNS、骨骼肌和心脏病理学对CHCHD 10 p. R15 L-ALS发病机制的贡献。表达野生型或ALS连接的CHCHD 10 p.R15L的转基因小鼠开发的CHCHD 10-R15 L小鼠在CNS中显示广泛的轴突生长尽管CNS、骨骼肌和心脏病理学,小鼠在运动测试中表现良好CHCHD 10-R15 L小鼠的早期死亡可能是由于心力衰竭分子生理学;分子生物学;神经科学
Mutations in coiled-coil-helix-coiled-coil-helix domain containing 10 (CHCHD10) have been identified in patients suffering from various degenerative diseases including mitochondrial myopathy, spinal muscular atrophy Jokela type, frontotemporal dementia, and/or amyotrophic lateral sclerosis (ALS). The pathogenic mechanism underlying CHCHD10-linked divergent disorders remains largely unknown. Here we show that transgenic mice overexpressing an ALS-linked CHCHD10 p.R15L mutation leads to an abbreviated lifespan compared with CHCHD10-WT transgenic mice. The occurrence and severity of the phenotype correlates to transgene copy number. Central nervous system (CNS), skeletal muscle, and cardiac pathology is apparent in CHCHD10-R15L transgenic mice. Despite the pathology, CHCHD10-R15L transgenic mice perform comparably to control mice in motor behavioral tasks until very close to death. Although paralysis is not observed, these models provide insight into the pleiotropic nature of CHCHD10 and suggest a contribution of CNS, skeletal muscle, and cardiac pathology to CHCHD10 p.R15L-ALS pathogenesis. Transgenic mice expressing wild-type or ALS-linked CHCHD10 p.R15L developed CHCHD10-R15L mice display widespread axonal swellings in the CNS Mice perform well in motor tests despite CNS, skeletal muscle, and cardiac pathology Early death of CHCHD10-R15L mice likely due to cardiac failure Molecular Physiology; Molecular Biology; Neuroscience
