Spinocerebellar ataxia type 3 (SCA3) is a progressive neurodegenerative disease caused by CAG repeat expansion of the ATXN3 gene encoding ataxin-3 protein and is mainly manifested by motor symptoms such as ataxia and non-motor symptoms such as cognitive dysfunction. In this study, we obtained skin fibroblasts from a SCA3 patient and successfully constructed induced pluripotent stem cells (iPSCs) using the reprogramming plasmids expressing OCT3/4, SOX2, KLF4, LIN28, and L-MYC. The generated iPSC line had a stable karyotype, expressed pluripotency markers, and could differentiate into all three germ layers in vitro. In addition, the iPSC line may be a useful model for identifying SCA3-related pathological mechanisms.
脊髓小脑性共济失调 3 型（SCA3）是一种由 ATXN3 基因 CAG 重复扩展引起的进行性神经退行性疾病，主要表现为共济失调等运动症状和认知功能障碍等非运动症状。本研究中，我们从 SCA3 患者获得皮肤成纤维细胞，并使用表达 OCT3/4、SOX2、KLF4、LIN28 和 L-MYC 的重编程质粒成功构建诱导多能干细胞（iPSC）。生成的 iPSC 系具有稳定的核型，表达多能性标志物，并能在体外分化为三个胚层。此外，该 iPSC 系可能是鉴定 SCA3 相关病理机制的有用模型。
