A lipid-based cell penetrating nano-assembly for RNAi-mediated anti-angiogenic cancer therapy

Abstract

Limited tumor tissue penetration is one of the key impeding factors retarding successful in vivo exploitations of anti-angiogenic cancer therapy. Herein we report on the design of a cell penetrating peptide-decorated lipid nano-assembly which, upon systemic administration, induces significant mouse tumor growth inhibition via enhanced tumor infiltration of encapsulated anti-angiogenic siRNA.
