Staying On Target with siRNAs: Issues and Solutions
Abstract: siRNA-mediated RNA interference (RNAi) has become a key tool in functional genomics. In this presentation, we will describe how a combination of (1) the first siRNA design algorithm, (2) pooling strategy, and (3) unique chemical modifications ensures high potency of chemically synthesized siRNAs.
We will demonstrate how sequence alignment algorithms (e.g.BLAST and Smith-Waterman) have limited ability to accurately filter siRNAs with potential off-target effects. Moreover, we will show that a primary source of off-target effects is derived from the “seed” region (nucleotides 2-8) of the siRNA’s antisense (guide) strand recognizing the 3’-UTR of an unintended target, resulting in silencing via a microRNA-like mechanism. Finally, we will present strategies that significantly reduce sequence-associated off-targets thus minimizing the incidence of false phenotypes.
The experimental approaches derived from these studies are expected to dramatically improve the quality and reliability of RNAi applications.
Topics presented in this seminar:
• Introduction to RNAi biology
• Strategies to ensure the function and specificity of siRNA sequences
• Transfections
• Use of appropriate controls |
