Anti-miR-27b and anti-miR-148a oligonucleotides as therapeutic tools for treating dyslipidemias and cardiovascular diseases
The present invention relates to anti-miR-27b and anti-miR-148a oligonucleotides that are capable of decreasing the level and/or activity of miR-27b and miR-148a, respectively. In conjunction with the oligonucleotide molecules of the present invention, the invention also provides a method for decreasing the level and/or activity of miR-27b and/or miR-148a in a cell. In a further embodiment, the invention provides a method for treating a disease, especially dyslipidemias and cardiovascular diseases.
1. A pharmaceutical composition comprising (i) an oligonucleotide, wherein said oligonucleotide is capable of decreasing the level and/or activity of miR-148a and comprises a sequence complimentary to nucleotides 2-8 at the 5′ end of the mature miRNA sequence of miR-148a, and (ii) one or more active substances selected from the group consisting of statins, niacin, bile-acid resins, fibric acid derivatives, cholesterol absorption inhibitors, and lipid-lowering drugs.
2. The pharmaceutical composition of claim 1 , wherein the mature miRNA sequence of miR-148a is 5′-UCAGUGCACUACAGAACUUUGU-3′ (SEQ ID NOS: 6, 60-61).
3. The pharmaceutical composition of claim 1 , wherein said oligonucleotide comprises the sequence 5′-(T/U)GCAC(T/U)G-3′ (SEQ ID NO: 117).
4. The pharmaceutical composition of claim 1 , wherein said oligonucleotide is a modified oligonucleotide.
5. A pharmaceutical composition comprising
(i) a first oligonucleotide, wherein said first oligonucleotide is capable of decreasing the level and/or activity of miR-148a and comprises a sequence complimentary to nucleotides 2-8 at the 5′ end of the mature miRNA sequence of miR-148a,
(ii) a second oligonucleotide, wherein said second oligonucleotide is capable of decreasing the level and/or activity of miR-27b, and/or a third oligonucleotide, wherein said third oligonucleotide is capable of decreasing the level and/or activity of miR-33, and
(iii) a pharmaceutically acceptable carrier or excipient.
6. The pharmaceutical composition of claim 5 , wherein the mature miRNA sequence of miR-148a is 5′-UCAGUGCACUACAGAACUUUGU-3′ (SEQ ID NOS: 6, 60-61).
7. The pharmaceutical composition of claim 5 , wherein said first oligonucleotide comprises the sequence 5′-(T/U)GCAC(T/U)G-3′ (SEQ ID NO: 117).
8. The pharmaceutical composition of claim 5 , wherein said first oligonucleotide and/or said second oligonucleotide and/or said third oligonucleotide is a modified oligonucleotide.
9. The pharmaceutical composition of claim 5 , wherein said second oligonucleotide comprises a sequence complimentary to nucleotides 2-8 at the 5′ end of the mature miRNA sequence of miR-27b.
10. The pharmaceutical composition of claim 9 , wherein the mature miRNA sequence of miR-27b is 5′-UUCACAGUGGCUAAGUUCUGC-3′ (SEQ ID NOS: 1, 58-59).
11. The pharmaceutical composition of claim 5 , wherein said second oligonucleotide comprises the sequence 5′-AC(T/U)G(T/U)GA-3′ (SEQ ID NO: 114).
