Abstract

The present invention relates to antisense oligonucleotides that modulate the expression of and/or function of Pyrroline-5-carboxylate reductase 1 (PYCR1), in particular, by targeting natural antisense polynucleotides of Pyrroline-5-carboxylate reductase 1 (PYCR1). The invention also relates to the identification of these antisense oligonucleotides and their use in treating diseases and disorders associated with the expression of PYCR1.

Claims

1. A method of identifying an antisense oligonucleotide which can modulate a function of and/or the expression of a Pyrroline-5-carboxylate reductase 1 (PYCR1) polynucleotide in patient cells or tissues in vivo or in vitro comprising:

identifying at least one antisense oligonucleotide of 10 to 30 nucleotides in length which is at least 90% complementary to a region of a polynucleotide antisense to an RNA transcribed from the PYCR1 polynucleotide;

contacting said at least one antisense oligonucleotide with said polynucleotide antisense to said RNA transcribed from the PYCR1 polynucleotide to form a hybrid;

measuring the thermal melting point of the hybrid of the at least one antisense oligonucleotide with said polynucleotide antisense to said RNA under stringent hybridization conditions;

selecting at least one antisense oligonucleotide having binding affinity to said polynucleotide based upon the thermal melting point results;

determining the modulation activity of the selected at least one antisense oligonucleotide targeted to said polynucleotide antisense to the RNA transcribed from the PYCR1 polynucleotide and

identifying at least one antisense oligonucleotide which modulates a function of and/or expression of the PYCR1 polynucleotide.

2. The method according to claim 1 comprising:

contacting said cells or tissues with at least one antisense oligonucleotide of 10 to 30 nucleotides in length that targets and specifically hybridizes to a region of a natural antisense polynucleotide of the Pyrroline-5-carboxylate reductase 1 (PYCR1) polynucleotide;

thereby modulating a function of and/or the expression of the Pyrroline-5-carboxylate reductase 1 (PYCR1) polynucleotide in patient cells or tissues in vivo or in vitro.

3. The method of claim 2, wherein a function of and/or the expression of the Pyrroline-5-carboxylate reductase 1 (PYCR1) is increased in vivo or in vitro with respect to a control.

4. The method of claim 2, wherein the at least one antisense oligonucleotide targets a natural antisense sequence of a Pyrroline-5-carboxylate reductase 1 (PYCR1) polynucleotide having SEQ ID NO:

2.

5. The method of claim 2, wherein the at least one antisense oligonucleotide targets a natural antisense polynucleotide comprising coding and/or non-coding nucleic acid sequences of a Pyrroline-5-carboxylate reductase 1 (PYCR1) polynucleotide.

6. The method of claim 2, wherein the at least one antisense oligonucleotide targets a natural antisense polynucleotide having overlapping and/or non-overlapping sequences with a Pyrroline-5-carboxylate reductase 1 (PYCR1) polynucleotide.

7. The method of claim 2, 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.

10. The method of claim 7, 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.

11. The method of claim 1, wherein the at least one antisense oligonucleotide comprises at least one oligonucleotide sequence set forth as SEQ ID NOS:

3 to 6.

12. The method according to claim 1 comprising:

contacting said cells or tissues with at least one short interfering RNA (siRNA) oligonucleotide 19 to 30 nucleotides in length, said at least one siRNA oligonucleotide being specific for a non-overlapping region of a natural antisense polynucleotide of a Pyrroline-5-carboxylate reductase 1 (PYCR1) polynucleotide.

13. The method of claim 7, wherein said oligonucleotide comprises at least one phosphorothioate internucleotide linkage.

14. The method of claim 7, wherein said oligonucleotide comprises a backbone of phosphorothioate internucleotide linkages.
