We describe the use of lentiviral vectors expressing small interfering RNAs (siRNAs) to knock down the expression of specific genes in vitro and in vivo. A lentiviral vector capable of generating siRNA specific for GFP after transduction of 293T-GFP cell lines showed no GFP fluorescence. Furthermore, no GFP-specific RNA could be detected. When eggs from GFP-positive transgenic mice were transduced with lentivirus-expressing siGFP virus, reduced fluorescence could be seen in blastocysts. More interestingly, pups from F(1) progeny, which expressed siGFP, showed considerably diminished fluorescence and decreased GFP. We propose that an approach of combining transgenesis by lentiviral vectors expressing siRNAs can be used successfully to generate a large number of mice in which the expression of a specific gene(s) can be down-regulated substantially. We believe that this approach of generating "knockdown" mice will aid in functional genomics.
