Patent ID: 8288356

Claim:
An oligomer of a contiguous sequence of 7, 8, 9 or 10 nucleotide units in length, for use in reducing the effective amount of a microRNA target in a cell or an organism, wherein at least 70% of the nucleotide units of the oligomer are selected from the group consisting of LNA (Locked Nucleic Acid) units and 2â€² substituted nucleotide analogues, and wherein at least 50% of the nucleotide units of the oligomer are LNA units, and wherein at least one of the internucleoside linkages present between the nucleotide units of the contiguous nucleotide sequence is a phosphorothioate internucleoside linkage, and wherein the contiguous nucleotide sequence is complementary to a corresponding renion of the microRNA sequence of miR-122 (SEQ ID NO: 150).
