摘要:
Polynucleotide delivery-enhancing polypeptides are admixed or complexed with, or conjugated to, nucleic acids for enhancing delivery the nucleic acids into cells. The transported nucleic acids are active in target cells as small inhibitory nucleic acids (siNAs) that modulate expression of target genes, mediated at least in part by RNA interference (RNAi). The siNA/polypeptide compositions and methods of the invention provide effective tools to modulate gene expression and alter phenotype in mammalian cells, including by altering phenotype in a manner that eliminates disease symptoms or alters disease potential in targeted cells or subject individuals to which the siNA/polypeptide compositions are administered.

摘要:
Cholesterol moieties are linked to specific ends of double-stranded RNA, preferably a small, interfering (si)RNA or to a dsHybrid. The dsHybrid has one strand comprised of DNA and one strand comprised of RNA. Preferably the sense strand is the DNA strand and the antisense strand is the RNA strand of the dsHybrid. The present invention is based upon the discovery that a cholesterol moiety, if linked to a specific end or ends of the sense or antisense strands of a siRNA, can enhance the delivery and silencing efficiency of the siRNA directed against its target message, in comparison with a corresponding, non-conjugated siRNA. Conjugated siRNAs and dsHybrids of the invention are optionally formulated with, or coordinately administered with, a secondary delivery-enhancing agent, such as a delivery-enhancing peptide, to enhance intracellular delivery and uptake of the conjugated siRNAs or dsHybrid.
