摘要:

肌萎缩侧索硬化作为一种神经退行性疾病,其发病机制至今尚未完全阐明,但炎症反应在其发病过程中扮演着重要角色。通过分析散发性肌萎缩侧索硬化和C9orf72相关的肌萎缩侧索硬化患者脑组织样本,探索是否存在影响炎症反应的潜在驱动基因以及潜在思路和靶点具有重要意义。因此实验基于可扩展算法的精确细胞网络重建方法(SJARACNe)的网络驱动基因分析工具NetBID2.0对散发性肌萎缩侧索硬化和C9orf72相关的肌萎缩侧索硬化患者的测序数据进行分析,发现OSMR基因可在肌萎缩侧索硬化发挥关键作用,其可能通过介导神经炎症反应参与肌萎缩侧索硬化发展。此外,还发现散发性肌萎缩侧索硬化和C9orf72相关的肌萎缩侧索硬化患者中OSMR的活性和表达存在差异,这暗示OSMR可能成为潜在的诊断和预后标志物。

Abstract: Amyotrophic lateral sclerosis is a neurodegenerative disease, and the molecular mechanism underlying its pathology remains poorly understood. However, inflammation is known to play an important role in the development of this condition. To identify driver genes that affect the inflammatory response in amyotrophic lateral sclerosis, as well as potential treatment targets, it is crucial to analyze brain tissue samples from patients with both sporadic amyotrophic lateral sclerosis and C9orf72-related amyotrophic lateral sclerosis. Therefore, in this study we used a network-driven gene analysis tool, NetBID2.0, which is based on SJARACNe, a scalable algorithm for the reconstruction of accurate cellular networks, to experimentally analyze sequencing data from patients with sporadic amyotrophic lateral sclerosis. The results showed that the OSMR gene is pathogenic in amyotrophic lateral sclerosis and participates in the progression of amyotrophic lateral sclerosis by mediating the neuroinflammatory response. Furthermore, there were differences in OSMR activity and expression between patients with sporadic amyotrophic lateral sclerosis and those with C9orf72-related amyotrophic lateral sclerosis. These findings suggest that OSMR may be a diagnostic and prognostic marker for amyotrophic lateral sclerosis.
