Treatment of insulin gene (INS) related diseases by inhibition of natural antisense transcript to an insulin gene (INS)
The present invention relates to antisense oligonucleotides that modulate the expression of and/or function of an Insulin gene (INS), in particular, by targeting natural antisense polynucleotides of an Insulin gene (INS). The invention also relates to the identification of these antisense oligonucleotides and their use in treating diseases and disorders associated with the expression of Insulin Gene (INS).
1. A method of upregulating a function of and/or the expression of an Insulin gene (INS) polynucleotide having SEQ ID NO: 1 in patient cells or tissues in vivo or in vitro comprising: contacting said patient cells or tissues with at least one oligonucleotide of 10 to 30 nucleotides in length that specifically targets and hybridizes to a region of a natural antisense polynucleotide of the Insulin gene (INS) polynucleotide wherein said natural antisense polynucleotide is selected from the group consisting of SEQ ID NOS: 2 and 3; thereby upregulating a function of and/or the expression of the Insulin gene (INS) polynucleotide in patient cells or tissues in vivo or in vitro.
2. The method of claim 1 , wherein a function of and/or the expression of the Insulin gene (INS) is increased in vivo or in vitro with respect to a control.
3. The method of claim 1 , wherein the at least one antisense oligonucleotide comprises one or more modifications selected from: at least one modified sugar moiety, at least one modified internucleoside linkage, at least one modified nucleotide, and combinations thereof.
4. The method of claim 3 , wherein the one or more modifications comprise at least one modified sugar moiety selected from: a 2′-O-methoxyethyl modified sugar moiety, a 2′-methoxy modified sugar moiety, a 2′-O-alkyl modified sugar moiety, a bicyclic sugar moiety, and combinations thereof.
5. The method of claim 3 , wherein the one or more modifications comprise at least one modified internucleoside linkage selected from: a phosphorothioate, alkylphosphonate, phosphorodithioate, alkylphosphonothioate, phosphoramidate, carbamate, carbonate, phosphate triester, acetamidate, carboxymethyl ester, and combinations thereof.
6. The method of claim 3 , wherein the one or more modifications comprise at least one modified nucleotide selected from: a peptide nucleic acid (PNA), a locked nucleic acid (LNA), an arabino-nucleic acid (FANA), an analogue, a derivative, and combinations thereof.
7. The method of claim 1 , wherein the at least one oligonucleotide comprises at least one oligonucleotide sequence set forth as SEQ ID NOS: 4 to 11.
