Administration of exogenous miRNA or siRNA

摘要

Certain genes controlled by endogenous miRNA are actually upregulated upon the transfection of exogenous mi/siRNA. Based on this, methods of determining whether administration of mi/siRNA will have a deleterious effect by upregulating certain genes are provided. Comparison of sequences of exogenous mi/siRNA allows selection of exogenous miRNA to be administered to cell to enhance or limit this affect, and therefore to control unwanted disregulation, or to upregulate an endogenous miRNA-regulated gene of interest.
