摘要:
This invention relates to the use of lipoproteins with oligonucleotides, both single and double stranded, and their use in delivering dsRNA for RNA interference. More specifically, the present invention relates to composititons containing oligonucleotides and alipoprotein E, which enables tissue-specific delivery and reduction of target expression.
摘要:
This invention relates to methods for increasing the efficiency of siRNA administrations via pre-administration of an agent that lowers LDL receptor levels.
摘要:
This invention relates to compositions containing double-stranded ribonucleic acid (dsRNA) in a lipid formulation, and methods of using the compositions to inhibit the expression of the Human kinesin family member 11 (Eg5) and Vascular Endothelial Growth Factor (VEGF), and methods of using the compositions to treat pathological processes mediated by Eg5 and VEGF expression, such as cancer.
摘要:
The invention relates to a double-stranded ribonucleic acid (dsRNA) for inhibiting the expression of the proprotein convertase subtilisin kexin 9 (PCSK9) gene, comprising an antisense strand having a nucleotide sequence which is less than 30 nucleotides in length, generally 19-25 nucleotides in length, and which is substantially complementary to at least a part of the PCSK9 gene. The invention also relates to a pharmaceutical composition comprising the dsRNA together with a pharmaceutically acceptable carrier; and methods for treating diseases caused by PCSK9 gene expression by using the pharmaceutical composition.
摘要:
The invention features a method of identifying therapeutically relevant compositions which include a therapeutic agent and 2,2-Dilinoley 1-4-dimethylaminomethyl-[1,3]-dioxolane by screening for an effect of the agent on the liver of a model subject.
摘要:
Poly(β-amino esters) prepared from the conjugate addition of bis(secondary amines) or primary amines to a bis(acrylate ester) are described. Methods of preparing these polymers from commercially available starting materials are also provided. These tertiary amine-containing polymers are preferably biodegradable and biocompatible and may be used in a variety of drug delivery systems. Given the poly(amine) nature of these polymers, they are particularly suited for the delivery of polynucleotides. Nanoparticles containing polymer/polynucleotide complexes have been prepared. The inventive polymers may also be used to encapsulate other agents to be delivered. They are particularly useful in delivering labile agents given their ability to buffer the pH of their surroundings. A system for preparing and screening polymers in parallel using semi-automated robotic fluid delivery systems is also provided.
摘要:
This invention relates to new formulated lipid particles (FLiPs) comprising at least one of a single or double stranded oligonucleotide, where the oligonucleotide has been conjugated to a lipophile and at least one of an emulsion or liposome to which the conjugated oligonucleotide has been aggregated, admixed or associated. These particles have surprisingly been shown to effectively deliver oligonucleotides to heart, lung and muscle where they effect gene silencing.
