摘要: 提供了一种小鼠早衰模型及其构建方法与应用,所述小鼠早衰模型是通过敲除小鼠骨髓来源细胞中的乙肝病毒X蛋白结合蛋白而获得的。该早衰小鼠在4-8个月龄时出现脱毛、衰老相关基因表达显著上调、血清中衰老相关的分泌表型因子上调、组织器官衰老等典型的早衰表型。通过操控骨髓来源的免疫细胞条件性敲除HBXIP,诱导小鼠早衰具有显著的创新性和良好的应用前景,可用于建立延缓衰老的个性化药物/食材/技术方法等的筛选平台,同时,可用于研究衰老相关疾病,如神经退行性疾病、代谢性疾病、自身免疫及炎症性疾病等发病机制研究,以及相关疾病的预防、诊断和治疗等技术和产品研发。

摘要: Described herein is the discovery that neither the nuclear localization signal (NLS) nor the prion-like domain (PLD) of TDP-43 is necessary for embryonic stem cell culture and differentiation into motor neurons in vitro. The ability of ES cells to express these TDP-43 mutants and differentiate into motor neurons that exhibit an ALS-like phenotype whereby the TDP-43 mutants redistribute to and aggregate in the cytoplasm and fail to regulate cryptic exon splicing allows these cells to act as a model of TDP-43 proteinopathy for the testing of candidate therapeutic agents that may resolve such proteinopathy. Additionally, these ES cells may be used to successfully generate non-human animals, e.g., mice, that also exhibit hallmark symptoms of ALS and that may be used in testing candidate agents useful in treating TDP-43 proteinopathies.
