Transcriptome analysis of oocytes and early embryos to demonstrate trancriptional regulation during mouse oocyte-to-embryo transition

In this study, we performed RNA-seq to elucidate how transcriptional activities of mouse oocytes and preimplantation embryos are regulated to control oocyte-to-embryo transition. Through analyzing transcriptome alterations of transgenically-modified growing oocytes, early embryos from aged female, early embryos treated with drugs disturbing proteostasis, and embryonic stem cells treated with drugs disturbing proteostasis, we identified critical roles of proteostasis in transcriptional regulation of mouse oocytes and early embryos.
