1. A single-stranded modified oligonucleotide consisting of 20 linked nucleosides and having:
- a gap segment consisting of ten linked deoxynucleosides;
a 5′
wing segment consisting of five linked nucleosides; and
a 3′
wing segment consisting of five linked nucleosides;
wherein the gap segment is positioned between the 5′
wing segment and the 3′
wing segment;
wherein each nucleoside of each wing segment comprises a 2′
O-methoxyethyl sugar;
wherein the internucleoside linkages within the gap segment, the linkages connecting the gap segment to the 5′ and
3′
wing segments, and the linkages for the 5′
-most and 3′
-most nucleosides of each wing segment are all phosphorothioate linkages; and
the internucleoside linkages connecting the rest of the nucleosides of both the 5′ and
3′
wing segments are phosphodiester linkages; and
wherein the nucleobase sequence of the oligonucleotide consists of the sequence recited in SEQ ID NO;
22,or a pharmaceutically acceptable salt thereof.
