Effect of Dnmt3a/3b transient silencing in WT iPSCs and comparison with miR-203 tKI iPSCs


ABSTRACT: The balance between pluripotency and differentiation is critical during development and regeneration. miR-203 is a microRNA previously involved in differentiation of different tissues as well as in tumor suppression in multiple malignancies. We have shown that miR-203 is able to promote differentiation of embryonic stem (ES) and induced pluripotent stem (iPS) cells without decreasing pluripotency. We have observed that transient expression of miR-203 significantly improves the efficiency of ES/iPS cells in the generation of quimeras and tetraploid complementation assays, in addition to inducing complex embryo-like structures when these pluripotent cells are injected in mice. Mechanistically, we have shown that miR-203 mediates such effects, at least in part, by modulating the levels of de novo DNA methyltransferases. In the present RNAseq we have transiently silenced the levels of DNMT3a/3b in order to compare their transcriptomic profile with that observed in PSCs transiently exponed to miR-203.
