One of the biggest challenges in developing microRNA (miRNA) based therapeutics is the method of delivery. Herein we report the design and synthesis of mPEG-poly(amino acid)s, which we used as a novel nanocarrier for the delivery of miRNA-139-5p. The PEG-poly(amino acid)s/miRNA-139-5p nanoparticle complex is more effective at suppressing tumor growth and migration in mice with colorectal cancer than when treated with miRNA-139-5p solution and blank nanoparticles individually. Our results suggest that PEG-poly(amino acid)s are a promising non-viral gene vector for the delivery of miRNAs to treat cancers.
