DELIVERY OF NUCLEIC ACIDS USING CELL-PENETRATING PEPTIDES

摘要

The present invention is based on the innovative concept of conjugating a cell- penetrating peptide (CPP), including a protein transduction domain, to a nucleic acid molecule to provide a nucleic acid-protein conjugate exhibiting enhanced cellular uptake. Accordingly, the invention provides a method of producing a cell permeable nucleic acid molecule conjugate nucleic acid including a nucleic acid conjugated with a homeodomain of an antennapedia homeotic transcription factor protein (Antp), or functional fragment thereof. The invention further provides compositions and methods treating a subject using the conjugates produced by the method described herein.
