Robust gene silencing mediated by antisense small RNAs in the pathogenic protist Entamoeba histolytica

Abstract excerpt

RNA interference uses small RNAs (sRNA), which target genes for sequence-specific silencing. The parasite Entamoeba histolytica contains an abundant repertoire of 27 nt antisense (AS) sRNA with 5'-polyphosphate termini, but their roles in regulating gene expression have not been well established. We demonstrate that a gene-coding region to which large numbers of AS sRNAs map can serve as a 'trigger' and silence...
