肿瘤治疗检测基因临床应用结果
摇床大鼠携带自然发生的突变,导致进行性共济失调,其特征是浦肯野细胞 (PC) 丢失。我们之前曾报道过将摇床轨迹精细映射到大鼠 X 染色体的长臂。在这项工作中,我们试图确定振动器表型背后的突变基因,并通过功能互补确认其身份。我们对候选区域进行了精细定位并分析了小脑转录组,确定了与疾病分离的 Slc9a6 基因中的 XM_217630.9 (Slc9a6):c.[191_195delinsA] 变体。我们使用小鼠 L7-6 (L7) 启动子生成了一种将 Slc9a6 表达靶向 PC 的腺相关病毒 (AAV)。我们通过脑室内注射在 PC 变性开始之前管理 AAV,发现它减少了振动器电机、分子和细胞表型。因此,Slc9a6 在摇床中发生突变,基于 AAV 的基因治疗可能是同样由 Slc9a6 突变引起的 Christianson 综合征的可行治疗策略。
肿瘤发生与革命国际数据库描述:
The shaker rat carries a naturally occurring mutation leading to progressive ataxia characterized by Purkinje cell (PC) loss. We previously reported on fine-mapping the shaker locus to the long arm of the rat X chromosome. In this work, we sought to identify the mutated gene underlying the shaker phenotype and confirm its identity by functional complementation. We fine-mapped the candidate region and analyzed cerebellar transcriptomes, identifying a XM_217630.9 (Slc9a6):c.[191_195delinsA] variant in the Slc9a6 gene that segregated with disease. We generated an adeno-associated virus (AAV) targeting Slc9a6 expression to PCs using the mouse L7-6 (L7) promoter. We administered the AAV prior to the onset of PC degeneration through intracerebroventricular injection and found that it reduced the shaker motor, molecular, and cellular phenotypes. Therefore, Slc9a6 is mutated in shaker and AAV-based gene therapy may be a viable therapeutic strategy for Christianson syndrome, also caused by Slc9a6 mutation.
