Bloom's syndrome gene-deficient phenotype in mouse primary cells induced by a modified tetracycline-controlled trans-silencer.

Abstract excerpt

We recently reported genome-wide bi-allelic mutagenesis and phenotype-based genetic screening by tetracycline-regulated disruption of the Bloom's syndrome gene (Blm) in mouse embryonic stem (ES) cells. However, the same approach was hampered in mouse tissues owing to leaky expression of the Blm gene, which is the major obstacle in the tetracycline regulatory system. Here we describe a single-chain reverse...
