Protocols for gene silencing in schistosomes.

ABSTRACT: Schistosomes are parasitic platyhelminths that infect over 200 million people globally. In recent years there have been many advances in schistosome genomics and proteomics and in the development of molecular tools for use with these parasites. Among the more promising methodologies is RNA interference (RNAi) which is a mechanism by which gene-specific double-stranded RNA (dsRNA) triggers degradation of homologous mRNA transcripts. We aim to develop effective protocols utilizing RNAi for use in the intra-mammalian life stages of Schistosoma mansoni. In this work, the gene encoding alkaline phosphatase (SmAP) was targeted by exposing the parasites to dsRNA encoding part of the SmAP coding region. SmAP is known to be expressed in a variety of parasite tissues. We report that both long dsRNAs
