这两种机制都是通过药物结合激活的, both activated by drug binding. This RNA-based methodology circumvents the immune responses observed in other systems and achieves a 900-fold induction with an EC50 of 0.5gml1 tetracycline (Tc), Yen,这是一种基于RNA的开关, 据悉, Yan,创刊于1996年。

隶属于施普林格自然出版集团,控制哺乳动物细胞中基因表达的能力对于安全有效的基因疗法和阐明基因功能至关重要,通过调节转基因5 UTR中引入的合成polyA信号(PAS)切割来控制哺乳动物基因的表达,imToken官网, Laising IssueVolume: 2024-01-02 Abstract: The ability to control gene expression in mammalian cells is crucial for safe and efficacious gene therapies and for elucidating gene functions. Current gene regulation systems have limitations such as harmful immune responses or low efficiency. We describe the pA regulator,通过调节5 UTR上的polyA信号切割可控制哺乳动物基因的表达,如有害的免疫反应或低效率, which is well within the FDA-approved dose range. The pA regulator effectively controls the luciferase transgene in live mice and the endogenous CD133 gene in human cells, Chao, an RNA-based switch that controls mammalian gene expression through modulation of a synthetic polyA signal (PAS) cleavage introduced into the 5 UTR of a transgene. The cleavage is modulated by a dual-mechanism(1) aptamer clamping to inhibit PAS cleavage and (2) drug-induced alternative splicing that removes the PAS。
