1. A method of selecting a modified 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:
- selecting at least one modified antisense oligonucleotide of 10 to 30 nucleotides in length which is at least 90% complementary to a region of a natural antisense polynucleotide the PYCR1 polynucleotide;
contacting said at least one modified antisense oligonucleotide with said natural antisense polynucleotide to form a hybrid;
measuring the thermal melting point of the hybrid of the at least one modified antisense oligonucleotide with said natural antisense polynucleotide under stringent hybridization conditions;
selecting at least one modified antisense oligonucleotide having binding affinity to said natural antisense polynucleotide based upon the thermal melting point results;
determining the modulation activity of the selected at least one modified antisense oligonucleotide having binding affinity to said natural antisense polynucleotide andselecting at least one modified antisense oligonucleotide which modulates a function of and/or expression of the PYCR1 polynucleotide wherein the at least one modified antisense oligonucleotide comprises one or more modifications selected from;
at least one modified sugar moiety, at least one modified intemucleoside linkage, at least one modified nucleotide, and combinations thereof.

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.
