比如最常见的广谱启动子CAG(CMV immediate-early enhancer chicken β-actin promoter),是通过将一个病毒的增强子序列和一个基因启动序列融合在一起,构建的启动子序列,能高效、广泛、长期的在动物细胞和组织中表达。但如果我们希望目的基因过表达/敲低的效果只发生在我们要研究的细胞或者组织中,就可以将AAV启动子...
2019年8月13日,AAV基因疗法的Asklepios BioPharmaceutical (AskBio) 宣布收购Synpromics,Synpromics致力于基因控制合成启动子技术、生物信息学和智能数据驱动设计领域,以实现更精确的细胞靶向和基因表达,该公司的启动子(Promoter)技术和制造系统授权给其它基因治疗公司以获得商业权益。AskBio成立于2001年,由Jude Samulski博士...

第一种情况,如果想要表达一个蛋白,那么在分子元件设计中包含 Promoter(启动子),只需要表达它就可以了,不需要去整合到基因组上,例如以前 Spark 和诺华生产的产品都是表达为主;如果想整合到基因组上并希望把它内源性表达,那么就取决于启动子的设计是否最优,所以高校研究中的设计和公司花费几亿美元所做的事...
