Local gene knockdown in the brain using viral-mediated RNA interference

Abstract

Conditional mutant techniques that allow spatial and temporal control over gene expression can be used to create mice with restricted genetic modifications. These mice serve as powerful disease models in which gene function in adult tissues can be specifically dissected. Current strategies for conditional genetic manipulation are inefficient, however, and often lack sufficient spatial control. Here we use viral-mediated RNA interference (RNAi) to generate a specific knockdown of Th, the gene encoding the dopamine synthesis enzyme tyrosine hydroxylase, within midbrain neurons of adult mice. This localized gene knockdown resulted in behavioral changes, including a motor performance deficit and reduced response to a psychostimulant. These results underscore the potential of using viral-mediated RNAi for the rapid production and testing of new genetic disease models. Similar strategies may be used in other model species, and may ultimately find applications in human gene therapy.

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.
