Recent work found that overexpression of short hairpin RNAs in cells could lead to mortality in mice, this was attributed to interference with the cellular machinery that makes miRNAs. This raised the issue of whether RNA interference-mediated silencing would be therapeutically possible. This paper shows that small interfering RNAs can be systemically administered and effectively suppress gene expression without compromising the activity of various liver miRNAs.
