2. The compound of claim 1 , wherein the modified antisense oligonucleotide is single-stranded.
3. The compound of claim 1 , wherein said modified antisense oligonucleotide is at least 95% complementary to SEQ ID NO: 1.
4. The compound of claim 1 , wherein said modified antisense oligonucleotide is at least 98% complementary to SEQ ID NO: 1.
5. The compound of claim 1 , wherein said modified antisense oligonucleotide is 100% complementary to SEQ ID NO: 1.
6. The compound of claim 1 , wherein at least one internucleoside linkage is a modified internucleoside linkage.
7. The compound of claim 6 , wherein each internucleoside linkage is a phosphorothioate internucleoside linkage.
8. The compound of claim 1 , wherein at least one nucleoside of the modified antisense oligonucleotide comprises a modified sugar.
9. The compound of claim 8 , wherein the at least one modified sugar is a bicyclic sugar.
10. The compound of claim 9 , wherein each of the at least one bicyclic sugar comprises a 4′-(CH 2 )—O-2′, 4′-(CH 2 ) 2 —O-2′, or 4′-CH(CH 3 )—O-2′ group.
11. The compound of claim 9 , wherein each of the at least one bicyclic sugar comprises a 4′-CH(CH 3 )—O-2′ bridge.
12. The compound of claim 8 , wherein at least one modified sugar comprises a 2′-O-methoxyethyl group.
13. The compound of claim 1 , wherein at least one nucleoside comprises a modified nucleobase.
14. The compound of claim 13 , wherein the modified nucleobase is a 5-methylcytosine.
15. The compound of claim of claim 1 , wherein the modified antisense oligonucleotide comprises:
a gap segment consisting of linked deoxynucleosides;
a 5′ wing segment consisting of linked nucleosides; and
a 3′ wing segment consisting of linked nucleosides;
wherein the gap segment is positioned between the 5′ wing segment and the 3′ wing segment and wherein each nucleoside of each wing segment comprises a modified sugar.
16. A composition comprising the compound of claim 1 or salt thereof and at least one of a pharmaceutically acceptable carrier or diluent.
17. A method of preventing, treating, ameliorating or delaying the onset of a disease or condition associated with GCCR in an animal comprising administering to the animal a therapeutically or prophylactically effective amount of compound of claim 1 or the composition of claim 16 wherein administering the compound or composition prevents, treats, ameliorates or delays the onset of the disease or condition.
18. The method of claim 17 , wherein the animal is human.
19. The method of claim 17 , wherein the disease or condition is diabetes.
20. The method of claim 17 , wherein the disease or condition is Type 2 diabetes.
21. The method of claim 17 , comprising co-administering the compound or composition and a second agent.
22. The method of claim 21 , wherein the second agent is a glucose lowering agent.
23. The method of claim 22 , wherein the compound or composition and the second agent are administered concomitantly.
24. The compound of claim 1 , wherein the modified oligonucleotide comprises a portion of at least 8 contiguous nucleobases of the sequence of SEQ ID Nos: 5, 8, 13, 14, 15, 16, 22, 23, 24, 30, 31, 32, 45, 46, 47, 48, 49, 50, 51, 52, 53, 54, 55, or 56.
