Reverse genetics in the rat: Advantages to using
in vivo RNAi over traditional knock-out methods
• Because of the small size of the sequences encoding shRNAs, these
sequences can be cloned in lentiviral vectors
• Production of transgenic founders with lentivirus is easy and efficient
• In vivo RNAi allows to generate animals with different degrees of gene
deficiency. An allelic series of hypomorphs is often more informative for
modeling human disease phenotypes
• Conditional in vivo RNAi approach is now feasable in the rat using tissue
specific promoters (RNA polymerase II promoters) driving the expression
of shRNAs (embedded in microRNAs)
