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.
