Aptamer mediated siRNA delivery

Nucleic acids that bind to cells and are subsequently internalized could prove to be novel delivery reagents. An anti-prostate specific membrane antigen aptamer that has previously been shown to bind to prostate tumor cells was coupled to siRNAs via a modular streptavidin bridge. The resulting conjugates could be simply added onto cells without any further preparation, and were taken up within ...

Nanolipoparticles-mediated MDR1 siRNA delivery: preparation, characterization and cellular uptake

Objective(s): Lipid-based nanoparticles (NLP) are PEGylated carriers composed of lipids and encapsulated nucleic acids with a diameter less than 100 nm. The presence of PEG in the NLP formulation improves the particle pharmacokinetic behavior. The purpose of this study was to prepare and characterize NLPs containing MDR1 siRNA and evaluate their cytotoxicity and cellular uptake. MDR1 siRNA coul...

Aptamer mediated niosomal drug delivery

Development of nanoscale carrier systems for targeted drug delivery is crucial for cancer treatment. The current methods of drug delivery exhibit some problems such as lack of therapy efficiency at the desired parts of the body, degradation of the drug before reaching the desired tissue and limitations in cellular penetration. In this work, a novel drug delivery platform was developed to overco...

A Universal Protein Tag for Delivery of SiRNA-Aptamer Chimeras

siRNA-aptamer chimeras have emerged as one of the most promising approaches for targeted delivery of siRNA due to the modularity of their diblock RNA structure, relatively lower cost over other targeted delivery approaches, and, most importantly, the outstanding potential for clinical translation. However, additional challenges must be addressed for efficient RNA interference (RNAi), in particu...

Cell-penetrating-peptide-mediated siRNA lung delivery.

The therapeutic application of siRNA (short interfering RNA) shows promise as an alternative approach to small-molecule inhibitors for the treatment of human disease. However, the major obstacle to its use has been the difficulty in delivering these large anionic molecules in vivo. A potential approach to solving this problem is the chemical conjugation of siRNA to the cationic CPPs (cell-penet...
