abstractText | We have developed a new vector, named pDECAP, to express long double-strand RNA (ds-RNA) from an RNA polymerase II (Pol II) promoter. Because the transcripts from pDECAP lack both the 5'-cap structure and the 3'-poly(A) tail that facilitate ds-RNA export to the cytoplasm, long ds-RNA from pDECAP does not induce the interferon response. Transgenic mice embryos expressing long ds-RNA for the transcriptional corepressor Ski from this vector exhibited phenotypes that were remarkably similar to those of Ski-deficient embryos, including defects of neural tube closure and eye formation. Thus, this vector provides a new tool to efficiently generate tissue-specific knockdown mice for studying gene function in whole animal systems. |
