Abstract:
In certain embodiments METHODS for conditional and target-specific recombination are provided where the methods comprise: providing a mammal comprising cells that express an ER-ligand-inducible CRE recombinase under the control of a promoter, and that comprises a nucleic acid sequence flanked by a pair of loxP sequences; and administering to the mammal biodegradable polymer nanoparticles containing an estrogen receptor ligand where the nanoparticles provide specific delivery to a target tissue of the estrogen receptor ligand thereby activating said CRE recombinase which performs target specific recombination of the nucleic acid between the loxP sequences in said target tissue.
Abstract:
The present invention provides, among other things, a method of intra-articular delivery of messenger RNA (mRNA), comprising administering into a joint of a subject in need of delivery a composition comprising an mRNA encoding a protein, such that the administering of the composition results in expression of the protein encoded by the mRNA in the joint.
Abstract:
L'invention vise un système pour l'intégration d'une molécule d'acide nucléique d'intérêt dans une région chromosomique associée au nucléole, comprenant au moins: - Un vecteur intégratif non viral se localisant dans le nucléole du noyau cellulaire, et dépourvu de source de recombinase fonctionnelle; et - Une source de recombinase fonctionnelle se localisant dans le nucléole du noyau cellulaire, fournie en trans dudit vecteur intégratif non viral.
Abstract:
Provided are a pharmaceutical composition and kit for prevention or treatment of arthritis, and a method of preventing or treating arthritis by using the same. The provided pharmaceutical composition, the kit, and the method have an excellent effect on the prevention and treatment of arthritis.
Abstract:
Provided are compositions and methods for efficient delivery of polynucleotides and/or small molecules to or into cells. The compostions comprises a peptide which as an excess postive charge and self assembles into homopentamers. The homopentmers can non-covalently bind polynucleotides. When encapsulated in lipid systems, such as liposomes, the lipoproteoplexes so formed, are capable of delivering both nucleic acids and small molecules to cells.
Abstract:
Recombinant viral vectors such as AAV vectors designed with expression cassettes that approach the natural packaging capacity of the virus, such as AAV are provided. The recombinant viral vectors reduce residual plasmid DNA impurities.
Abstract:
The invention provides a composition comprising two or more of a) genetic material; b) a condensing agent; c) a membrane destabilizing agent; d) a targeting/stabilizing agent, and optionally e) an ionic cross-linking agent. The components of the composition can self-assemble to form particles via electrostatic and/or lipophilic interactions. Methods of making and using the composition are also provided. The compositions can be used, for example, to transfer genetic material to cells in vitro or in vivo.
