在这里, 我们描述了一个协议, 以生成一个可行的女性小鼠模型与非随机 X 染色体失活, 即, 母体遗传 x 染色体是不活跃的100% 的细胞。我们还描述了一个方案, 以测试可行性, 耐受性和安全性的药理作用, 在体内的非活性 X 染色体。

该协议可用于生成非随机小鼠模型,用于测试和量化活鼠大脑中不活跃的 X 链接 Mecp2 染色体的重新激活。此模型可以很容易地修改,以研究其他 X 相关疾病模型(如 DDX3X 综合征)中的 Xi 重新激活。我是桑奇塔·巴特纳加尔实验室的博士后,我将和郑泽民一起演示手术过程。

首先将麻醉鼠标定位在立体定向平台中,将切口钩在鼻子抑制器的咬杆上。拧紧鼻夹,同时保持鼠标头在水平平面上。调整耳杆的高度以到达耳道的耳道部分,以保持头部固定。
