Specific inhibition of gene expression using a stably integrated, inducible small-interfering-RNA vector.

Abstract

We have designed a doxycycline-regulated form of the H1 promoter of RNA polymerase III that allows the inducible knockdown of gene expression by small interfering RNAs (siRNAs). As a proof-of-principle, we have targeted beta-catenin in colorectal cancer (CRC) cells. T-cell factor (TCF) target-gene expression is induced by accumulated beta-catenin, and is… (More)
