品系描述

将CreERT2-pA插入到小鼠Nkx2-1基因起始密码子处。
应用领域:Nkx2-1调节肺的发育,在成年的II型肺细胞和细支气管细胞中表达,Nkx2-1是肿瘤进展的标志物,可用于肺部肿瘤包括肺腺癌的研究

验证数据

图 1 Tamoxifen诱导后,Nkx2-1CreERT2/+; Rosa26tdTomato/+ 小鼠肺上皮细胞中tdTomato表达情况。

经Tamoxifen诱导后,Nkx2-1CreERT2/+; Rosa26tdTomato/+ 双转基因鼠,可在小鼠某些支气管和肺泡的上皮细胞中表达tdTomato。


图 2  Tamoxifen 诱导后,Nkx2-1CreERT2/+; Rosa26tdTomato/+ 小鼠各组织中tdTomato的表达情况。

CreERT2蛋白的活性在肺中被Tamoxifen依赖性诱导表达。此外,在垂体、视网膜、心脏、肝脏、胃、大肠、小肠、肾脏和胰腺等中都没有检测到tdTomato的表达。
