title: An siRNA-based system for differential regulation of ectopic gene expression constructs.
abstract: We describe an siRNA (short interfering RNA)-based approach for temporary and reversible regulation of engineered expression constructs in cells. Control of cloned genes can be achieved by cotransfection of unique siRNAs, complementary to artificial target sequences, which are integral parts of an expression vector. Application of this method allows simultaneous or mutual-differential regulation of two or more gene constructs within the same cell, reducing unwanted side effects. This method provides several advantages over promoter regulatory systems employing chemical compounds.
