siRNA EXPRESSION SYSTEM AND PROCESS FO RPRODUCING FUNCTIONAL GENE KNOCKDOWN CELL OR THE LIKE USING THE SAME

摘要

The in vivo siRNA expression system according to this invention is a system that intracellularly expresses small interfering (si) RNAs and comprises antisense and sense code DNAs coding for antisense and sense RNAs targeting any region of a target gene mRNA and one or more promoters that function to express the antisense and sense RNAs from the antisense and sense code DNAs, respectively.
