MDRNA, Inc. Completes Exclusive License Agreement to RNAi Delivery Peptides
News Aug 20, 2008
MDRNA, Inc. has announced that it has signed an exclusive license agreement to intellectual property from the University of Michigan covering cationic peptides for enhanced delivery of nucleic acids. Terms of the agreement were not disclosed.
“The University of Michigan peptides have unique characteristics that we believe play an important role in improving the efficacy of delivery of RNAi-based therapeutics,” stated Michael Houston, Ph.D., Vice President of Chemistry and Formulations.
“These cationic peptides have the potential of being critical components of RNAi-based therapeutic formulations. We are currently using these peptides to create siRNA nanoparticles to enhance gene expression knockdown. Together with the DiLA2 Platform of novel delivery lipids, these delivery peptides improve the therapeutic potential of our drug candidates.”
The small cationic peptides covered by the University of Michigan intellectual property are capable of forming stable siRNA nanoparticle complexes, thereby protecting the siRNA while increasing the efficiency and efficacy of the formulations.
In addition, they can also enhance endosomal release, an important step in delivering siRNAs to their site of action inside cells. Results to date have demonstrated both enhanced knockdown of target proteins in vivo as well as improvement in delivery efficiency.
Schizophrenics' Blood Contains RNA From More MicrobesNews
The blood of schizophrenia patients features genetic material from more types of microorganisms than that of people without the debilitating mental illness, research at Oregon State University has found. What’s not known is whether that’s a cause or effect of the severe, chronic condition that strikes about one person in 100.READ MORE
