Outline of Final Research Achievements |
Non coding RNA RNY1 (Y1) is a transiently expressed factor during early iPS reprogramming, and induction efficiency to iPS cells is decreased by its knockdown. We analyzed the molecular machinery related to RNY1 and RO60, which form a complex, during cellular reprogramming. DDX6 protein, which involves in RNA metabolism was identified, and the knockout cell for DDX6 also showed a drastic decrease in induction efficiency. We found that the RNY1/RO60/DDX6 axis attributes to mesenchymal epithelial transition, which is essential for initial phase in iPS reprogramming. and proposed a putative molecular model for parental mRNA decay in the nexus of a set of miRNAs.
