Abstract: The present invention is directed to RNA oligonucleotides or complexes of RNA oligonucleotides, denoted herein together as RNA complexes, containing at least one, but optionally more that one, hydroxymethyl substituted nucleotide monomer(s). By a hydroxymethyl substituted nucleotide monomer is understood a nucleotide monomer containing a hydroxymethyl group (that may be unsubstituted, O-substituted for example with a conjugating group, or converted into an optionally substituted or conjugated aminomethyl group). This hydroxymethyl group is not partaking in formation of an internucleotide linkage and is not the hydroxymethyl group (containing the 5?-hydroxy group) of a natural RNA monomer. The RNA complexes of the invention may be useful for therapeutic applications, diagnostic applications or research applications.

Abstract: Activity-generating delivery molecules comprising the structure R3—(C?O)-Xaa-NH—R4 wherein Xaa is any D- or L-amino acid residue with a non-hydrogen, substituted or unsubstituted side chain, R3—(C?O)— and —NH—R4 are independently a long chain group, each long chain group containing one or more carbon-carbon double bonds, and salts, compositions and methods of use thereof. The activity-generating delivery compounds and compositions are useful for generating activity of an active agent in a cell, tissue, or subject.

Abstract: 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.
