Treatment of reprogramming factor related diseases by inhibition of natural antisense transcript to a reprogramming factor
The present invention relates to antisense oligonucleotides that modulate the expression of and/or function of a Reprogramming factor, in particular, by targeting natural antisense polynucleotides of a Reprogramming factor. The invention also relates to the identification of these antisense oligonucleotides and their use in treating diseases and disorders associated with the expression of Reprogramming factors.
