Abstract

Putative U6snRNA polymerase III (PolIII) promoters were cloned from the Anopheles gambiae and Aedes aegypti genomes. The PolIII promoters were tested for their ability to express short-hairpin RNA (shRNA) targeted to firefly luciferase and to mediate RNA interference (RNAi) knockdown of a co-transfected luciferase reporter gene vector in AG-55 Anopheles gambiae and ATC-10 Aedes aegypti cells. Promoters capable of silencing expression of the co-transfected luciferase plasmid by up to 95% in AG-55 cells and up to 75% in ATC-10 cells were identified. RNase protection experiments allowed detection of the 19 nt luciferase short-interfering RNA (siRNA) in transfected cells. These findings indicate that mosquito U6snRNA gene promoters can be used for production of shRNA to induce the RNAi response in mosquito cells.
