Tissue Specificity of Caenorhabditis elegans Enhanced RNA Interference Mutants

Gene knockdown by RNA interference (RNAi) in Caenorhabditis elegans is readily achieved by feeding bacteria expressing double-stranded RNA (dsRNA). Enhanced RNAi (Eri) mutants facilitate RNAi due to their hypersensitivity to dsRNA. Here, we compare eight Eri mutants for sensitivity to ingested dsRNA, targeting a variety of tissue-specific genes.
