Amylose-Based Cationic Star Polymers for siRNA Delivery
A new siRNA delivery system using a cationic glyco-star polymer is described. Spermine-modified 8-arm amylose star polymer (with a degree of polymerization of approximately 60 per arm) was synthesized by chemoenzymatic methods. The cationic star polymer effectively bound to siRNA and formed spherical complexes with an average hydrodynamic diameter of 230 nm. The cationic 8-arm star polymer comp...
متن کاملCationic lipids and polymers for gene delivery
Gene therapy, aiming to eradicate causes rather than symptoms of diseases, is believed to be the therapy of the future. A new promising area for the application of gene therapy is the emerging field of regenerative medicine, where gene delivery can be used to enhance or modify cell functions in an organ/tissue or in engineered substitutes. The aim of gene therapy is to achieve the expression of...

متن کاملEfficient delivery of NF-κB siRNA to human retinal pigment epithelial cells with hyperbranched cationic polysaccharide derivative-based nanoparticles
A hyperbranched cationic polysaccharide derivative-mediated small interfering (si)RNA interference strategy was proposed to inhibit nuclear transcription factor-kappa B (NF-κB) activation in human retinal pigment epithelial (hRPE) cells for the gene therapy of diabetic retinopathy. Two hyperbranched cationic polysaccharide derivatives containing the same amount of cationic residues, but with di...
متن کاملImpact of lipid substitution on assembly and delivery of siRNA by cationic polymers.
Characterization of a polymer library engineered to enhance their ability to protect and deliver their nucleotide cargo to the cells is reported. The ζ-potential continuously increased with higher polymer:siRNA weight ratio, and the ζ-potential of lipid-modified polymers:siRNA complexes were higher than PEI2 at all ratios. At polymer:siRNA ratio of 1:1, all lipid-substituted polymers showed com...
