Abstract
Bacteriophage phi29 DNA packaging motor is geared by a ring consisting of six packaging RNA (pRNA) molecules. pRNA is able to form a multimeric complex via the interaction of two reengineered interlocking loops. This unique feature makes it an ideal polyvalent vehicle for nanomachine fabrication, pathogen detection, and delivery of siRNA or other therapeutics. This review describes methods in using pRNA as a building block for the construction of RNA dimers, trimers, and hexamers as nanoparticles in medical applications. Methods for industrial-scale production of large and stable RNA nanoparticles will be introduced. The unique favorable PK (pharmacokinetics) profile with a half life (T1/2) of 5-10Â h comparing to 0.25 of conventional 2â²-F siRNA, and advantageous in vivo features such as non-toxicity, non-induction of interferons or non-stimulating of cytokine response in animals will also be reviewed.
