Shank3基因突变鼠行为及脑内机制变化研究进展
摘 要:
Shank3基因可编码多结构域SHANK3蛋白,该蛋白是兴奋性突触后致密区的支架蛋白,其不同结构域可供各种离子通道、受体和细胞内骨架直接或间接锚定,形成突触后重要的功能复合体。Shank3基因在神经系统分布较多,对维持神经元突触可塑性有重要作用。近年来,Shank3基因的突变被发现与多种神经发育障碍性疾病密切相关。不少实验室开始通过基因编辑技术构建基于Shank3基因突变的转基因鼠类模型,以研究该基因突变引起的疾病的机制问题,探究疾病的可能治疗方法。该文通过文献查阅,对基于Shank3基因突变的转基因鼠造成的异常行为及脑机制进行综述,探究该基因突变在神经疾病机制研究中的重要意义,为后续Shank3基因模式动物的深入研究做铺垫。

Abstract:
Shank3 gene encodes the multi-domain SHANK3 protein, which relates to a variety of scaffolding proteins to form functional complexes. It is widely distributed in the nervous system and plays an important role in maintaining synaptic plasticity of neurons. In recent years, studies have found that the mutation of Shank3 gene is significantly associated with a variety of neurodevelopmental disorders. Many laboratories have started to construct model animals through gene editing technology in order to study the mechanism of Shank3-related diseases and explore possible treatments. This article reviewed the behavior and brain mechanism of Shank3 mutant mice/rats, explored the significance of its mutation in the mechanism research of neurological diseases, laying a foundation for further research on Shank3 gene model animals.
