production methods of functional gene knockdown cells or the like using the same, and siRNA expression system

摘要

A system for expressing the (short interfering) RNA si in the cell, the antisense-encoding DNA that encodes an antisense RNA against any region of the target gene mRNA, in vivo siRNA expression system of the present invention the target a sense code DNA encoding a sense RNA of any region of the gene mRNA, promoter and one or more the expression of the sense RNA and the antisense RNA from the sense-encoding DNA and the antisense-encoding DNA is provided there.
