EWING'S SARCOMA BIFUNCTIONAL SHRNA DESIGN

摘要

The present invention includes compositions and methods of making and using an imaging label comprising an expression vector comprising a promoter; and a nucleic acid insert operably linked to the promoter, wherein the insert encodes one or more short hairpin RNAs (shRNA) capable of inhibiting an expression of a target gene sequence that is a EWS-FLI1 fusion gene, a EWSRl-ERG fusion gene, or both in Ewing's sarcoma via RNA interference; wherein the one or more shRNA comprise a bifunctional RNA molecule that activates a cleavage-dependent and a cleavage-independent RNA-induced silencing complex for reducing the expression level of the target gene.
