Abstract: The present invention relates to oligomer compounds (oligomers), which target PCSK9 mRNA in a cell, leading to reduced expression of PCSK9. Reduction of PCSK9 expression is beneficial for the treatment of certain medical disorders, such as hypercholesterolemia and related disorders.

Abstract: The invention provides pharmaceutical compositions comprising short single stranded oligonucleotides, of length of between 8 and 26 nucleobases which are complementary to human microRNAs selected from the group consisting of miR19b, miR21, miR122a, miR155 and miR375. The short oligonucleotides are particularly effective at alleviating miRNA repression in vivo. It is found that the incorporation of high affinity nucleotide analogues into the oligonucleotides results in highly effective anti-microRNA molecules which appear to function via the formation of almost irreversible duplexes with the miRNA target, rather than RNA cleavage based mechanisms, such as mechanisms associated with RNaseH or RISC.

Abstract: The invention provides pharmaceutical compositions comprising short single stranded oligonucleotides, of length of between 8 and 17 nucleobases which are complementary to human microRNAs. The short oligonucleotides are particularly effective at alleviating miRNA repression in vivo. It is found that the incorporation of high affinity nucleotide analogues into the oligonucleotides results in highly effective anti-microRNA molecules which appear to function via the formation of almost irreversible duplexes with the miRNA target, rather than RNA cleavage based mechanisms, such as mechanisms associated with RNaseH or RISC.

Abstract: The present invention relates to very short heavily modified oligonucleotides which target and inhibit microRNAs in vivo, and their use in medicaments and pharmaceutical compositions.

Abstract: The current invention provides oligonucleotides which comprise a dinucleotide consisting of a 5? locked nucleic acid (LNA), a phosphorothioate internucleoside linkage bond to a 3? RNA or RNA analogue. The dinucleotide reduces the strength of hybridization of the oligonucleotide to a complementary nucleic acid target. The modification can be used to modulate hybridisation properties in both single stranded oligonucleotides and in double stranded siRNA complexes, particularly in oligonucleotides where the use of LNA results in excessively strong hybridisation properties.

Abstract: The present invention is directed to modified siRNA which are significantly impaired in their ability to support cleavage of mRNA when incorporated into a RISC complex. Such modified siRNA may be useful as therapeutic agents, e.g., in the treatment of various cancer forms. More particularly, the modified siRNA comprises a sense strand and an antisense strand, wherein the sense strand contains a modified RNA nucleotide in at least one of positions 8-14, calculated from the 5?-end.

Abstract: The present invention is directed to novel double-stranded short interfering (siRNA) analogues comprising locked nucleic acid (LNA) monomers. Such compounds induces sequence-specific post-transcriptional gene silencing in many organisms by a process known as RNA interference (RNAi). The compounds disclosed herein has improved properties compared to non-modified siRNAs and may, accordingly, be useful as therapeutic agents, e.g., in the treatment of various cancer forms. More particularly, the present invention is directed to siRNA analogues comprising a sense strand and an antisense strand, wherein each strand comprises 12-35 nucleotides and wherein the siRNA analogues comprise at least one locked nucleic acid (LNA) monomer.
