Abstract

RNA interference (RNAi) is a cellular mechanism that is often exploited as a technique for quelling the expression of a specific gene. RNAi studies are carried out in vivo, making this a powerful means for the study of protein function in situ Several trypanosomatids, including those organisms responsible for human and animal diseases, naturally possess the machinery necessary for RNAi manipulations. This allows for the use of RNAi in unraveling many of the pressing questions regarding the parasite's unique biology. The completion of the Trypanosoma brucei genome sequence, coupled with several powerful genetic tools, has resulted in widespread utilization of RNAi in this organism. The key steps for RNAi-based reduction of gene expression, including parasite cell culture, DNA transfection, RNAi expression, and experimental execution, are discussed with a focus on procyclic forms of Trypanosoma brucei.
