Abstract Small interfering RNAs (siRNAs) can specific silence target genes,and are widely used to elucidate gene function,indentify drug targets and develop more specific therapeutics than are currently available. Off-target effects (OTEs) can complicate the interpretation of phenotypic effects in gene-silencing experiments and can potentially lead to unwanted toxicities. siRNAs OTEs include microRNA-like off-target effects, immune stimulation and saturation of the RNAi machinery. The types of off-target effects of siRNAs and methods to mitigate them was focused, to help enable effective application of RNAi technology.
