JAMA Neurol:C9orf72重复扩增序列患者预后研究

2019-11-25 MedSci MedSci原创

研究考察了c9orf72重复扩增序列相关疾病患者的生存期差异,其中c9ALS预后最差

C9orf72重复扩增序列(c9或 c9orf72RE)与肌萎缩侧索硬化(ALS)患者生存期缩短相关,近日研究人员考察了c9orf72与额颞叶痴呆(FTD)及ALS预后之间的关系。

本次研究为系统综述及荟萃分析,考察2011-19年间相关研究数据,研究的主要终点是生存期。

206个研究,总计1060名患者,其中c9ALS患者455人、c9FTD患者 296人; c9ALS-FTD患者198人、非典型表型患者111人。c9ALS、c9FTD、c9ALS-FTD患者的平均生存期差异显著,分别为2.8年、9.0年、3.0年,而非典型表型的生存期差异较大。相比于其他患者,c9ALS老年以及球后发作人群的生存期显著缩短。经神经病理证实的额颞叶变性-TDP-43、运动神经元病-TDP-43和额颞叶变性-运动神经元病-TDP-43的临床表型差异显著,对生存期有影响。

研究考察了c9orf72重复扩增序列相关疾病患者的生存期差异,其中c9ALS预后最差。

JAMA Neurol:C9orf72突变携带者症状前认知及脑结构变化

研究发现,C9orf72突变携带者存在认知、脑结构以及脑微结构的改变,实践能力下降以及左侧缘上回局灶性萎缩是C9orf72突变相关的早期表型,而白质改变是额颞叶变性以及肌萎缩性侧索硬化的症状表现

Brain:科学家提出治疗渐冻人症新策略

4月1日,《大脑》杂志在线发表了题为《重新激活无义介导的mRNA降解通路可有效对抗C9orf72双肽重复序列的神经毒性》的研究论文。该项研究揭示了导致部分肌萎缩性侧索硬化症(ALS)的新机制,证实了激活无义介导的mRNA降解通路可以作为治疗ALS的新策略,并发现了一种现有的用于治疗哮喘的药物有可能成为治疗ALS的新药。该研究工作由中国科学院神经科学研究所、神经科学国家重点实验室徐进研究组完成。

Nature:与C9orf72相关神经疾病中的RNA毒性

重复扩张(指产生一前一后重复的RNA序列的额外版本的突变)是造成40多种遗传疾病的原因,它们一般会导致神经问题和神经肌肉问题。 C9orf72六核苷酸重复扩张已被发现是造成“肌萎缩侧索硬化”(ALS)和“额颞痴呆” (FTD)这两种疾病的原因。正常的C9orf72含有多达25个重复片段,而患病者的该基因则会含有数千个。 这项研究表明,RNA毒性的增加在ALS/FTD两种疾病中是造成与C9orf

Nature:常见基因突变为何会引发痴呆

近日,一项刊登在国际杂志Nature上的研究论文中,来自约翰霍普金斯大学的研究人员通过研究揭示常见的基因突变如何引发大脑损伤相关的肌萎缩侧索硬化症(ALS)和额颞痴呆(frontotemporal dementia,FTD),研究者表示,位于人类9号染色体上的C9orf72基因的改变会促进RNA分子阻断蛋白运输的关键通路,从而引发大脑细胞核外部的分子“交通拥挤”,进而影响大脑的正常功能。研究者Je
