4 or SEQ ID NO;

151.

4. The compound of claim 2, wherein at least one internucleoside linkage of said modified oligonucleotide is a modified internucleoside linkage.

5. The compound of claim 4, wherein each internucleoside linkage of said modified oligonucleotide is a phosphorothioate internucleoside linkage.

6. The compound of claim 2, wherein at least one nucleoside of said modified oligonucleotide comprises a modified sugar.

7. The compound of claim 6, wherein at least one modified sugar is a bicyclic sugar.

8. The compound of claim 6, wherein at least one modified sugar comprises a 2′

-O-methoxyethyl or a 4′

-(CH₂)_n—

O-2′

bridge, wherein n is 1 or 2.

9. The compound of claim 2, wherein at least one nucleoside of said modified oligonucleotide comprises a modified nucleobase.

10. The compound of claim 9, wherein the modified nucleobase is a 5-methylcytosine.

11. The compound of claim 1, wherein the modified oligonucleotide comprises:

a gap segment consisting of linked deoxynucleosides;

a 5′

wing segment consisting of linked nucleosides;

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.

12. The compound of claim 11, wherein the modified oligonucleotide comprises:
