Description
技术领域

背景技术
公开该背景技术部分的信息仅仅旨在增加对本发明的总体背景的理解,而不必然被视为承认或以任何形式暗示该信息构成已经成为本领域一般技术人员所公知的现有技术。
JunD是一种属于多功能激活剂蛋白-1(activating protein-1,AP-1)家族的转录因子,可以激活或抑制多种靶基因的表达。在生长发育过程中,在各种细胞类型中都呈现出组成性表达。近20年的临床数据及分子生物学研究表明,JunD蛋白的功能受多个复杂过程调控,包括转录控制、转录后调节、蛋白质翻译后修饰及蛋白-蛋白相互作用等。JunD基因表达的精细调控及JunD蛋白与其它蛋白之间的相互作用可调节细胞增殖、分化和凋亡等过程。JunD蛋白活性异常会导致肿瘤、代谢及病毒类疾病的发生。JunD蛋白的转录激活及抑制受复杂调控网络调控,在这个网络调节下,JunD蛋白在细胞的生长调控过程中发挥重要作用。
现有研究指出,在II型糖尿病(T2D)中,氧化应激导致胰腺β细胞功能障碍和丧失。而JUND是胰岛β细胞中的应激反应因子,导致氧化还原失衡,并导致氧化还原失衡和生理病理相关应激期间的细胞凋亡。因此通过干扰JUND的表达可以深入探究JUND在胰岛β细胞中发挥的功能,为研究以JUND作为糖尿病治疗靶点提供技术支持。而目前尚缺乏便捷、有效的干扰胰岛β细胞中JUND的表达技术。
