Photoswitchable -functionalized tetrafluorinated azobenzene-modified siRNAs (F-azo-siRNAs) were synthesized using solid-phase phosphoramidite chemistry. The activity of an F-azo-siRNA targeting enhanced green fluorescence protein (eGFP) in transgenic (Tg) Japanese Medaka () was reversibly photocontrolled with blue (470 nm) and green (530 nm) light, to activate and inactivate the siRNA, respectively. This study highlights the first reversible study with photoswitchable siRNA. Controlling siRNA function reversibly could open new opportunities for biotech research to better understand gene function and cellular mechanisms.
采用固相亚磷酰胺化学法合成了光可切换功能化全氟偶氮苯修饰的小干扰 RNA(F-azo-siRNA)。靶向增强型绿色荧光蛋白(eGFP)的 F-azo-siRNA 在转基因(Tg)日本青鳉中的活性可分别通过蓝光(470nm)和绿光(530nm)进行可逆光控,以激活和失活 siRNA。本研究首次报道了光可切换 siRNA 的可逆调控。siRNA 功能的可逆调控可能为生物技术研究开辟新的机会,以更好地理解基因功能和细胞机制。
