一个理想的转基因基因表达系统是可诱导的,无泄漏的,并被目标生物很好地耐受。虽然前者已经令人满意地实现了,但现有系统的漏水和沉重的生理负担仍然是其成功实施的突出障碍。在这里,我们描述了一种在果蝇中无泄漏表达转基因的新系统。PRExpress是基于由内源成分、可诱导的HSP70启动子和由Polycomb组的表观遗传染色质调节因子控制的Polycomb反应元件(Pre)的多聚体拷贝构建的单一转基因构建物。我们证明了该系统是无泄漏的、快速且强诱导的、可逆的。为了使PRExpress的应用程序用户友好,我们通过特定地点的集成来交付施工。
An ideal transgenic gene expression system is inducible, non-leaky, and well tolerated by the target organism. While the former has been satisfactorily realized, leakiness and heavy physiological burden imposed by the existing systems are still prominent hurdles in their successful implementation. Here we describe a new system for non-leaky expression of transgenes in Drosophila. PRExpress is based on a single transgenic construct built from endogenous components, the inducible hsp70 promoter and a multimerized copy of a Polycomb response element (PRE) controlled by epigenetic chromatin regulators of the Polycomb group. We show that this system is non-leaky, rapidly and strongly inducible, and reversible. To make the application of PRExpress user-friendly, we deliver the construct via site-specific integration.
