An Optimized microRNA Backbone for Effective Single-Copy RNAi
Open accessAbstract
Short hairpin RNA (shRNA) technology enables stable and regulated gene repression. For establishing experimentally versatile RNAi tools and minimizing toxicities, synthetic shRNAs can be embedded into endogenous microRNA contexts. However, due to our incomplete understanding of microRNA biogenesis, such "shRNAmirs" often fail to trigger potent knockdown, especially when expressed from a single genomic copy. Following recent advances in design of synthetic shRNAmir stems, here we take a systematic approach to optimize the experimental miR-30 backbone. Among several favorable features, we identify a conserved element 3' of the basal stem as critically required for optimal shRNAmir processing and implement it in an optimized backbone termed "miR-E", which strongly increases mature shRNA levels and knockdown efficacy. Existing miR-30 reagents can be easily converted to miR-E, and its combination with up-to-date design rules establishes a validated and accessible platform for generating effective single-copy shRNA libraries that will facilitate the functional annotation of the genome.

About these checks
Registry, retraction, Cites and statistics results are computed, not judged, with one exception: a printed reference that no index lists is read once by a model before it counts as a citation error. Claims are extracted by a model and kept only when their quote appears verbatim in the text; each cited source is then checked, with a model’s help, for whether it says what the claim relies on. Those verdicts can be wrong — read the claim’s quote and the cited source before relying on one.
Statistics and arithmetic are recomputed, not judged.
Confidence bands are shown only for fields calibrated on our annotated test set. None is calibrated yet, so no band is shown.
