Title	Distinct transcriptome, translatome, and proteome reprogramming during the oocyte-to-embryo transition
Description	The oocyte-to-embryo transition converts terminally differentiated gametes into a totipotent embryo. Fertilized embryos undergo the resetting of the transcriptional program as the zygotic genome is activated from a silenced state started from the late-stage oocyte. How transcriptome, translatome, and proteome interplay in this critical developmental window remains poorly understood. Utilizing a highly sensitive mass spectrometry, we obtained high-quality proteome landscapes including nearly 6,000 genes spanning 10 stages, from the mouse full-grown oocyte (FGO) to blastocyst, using 100 oocytes/embryos at each stage. By integrative analysis with corresponding transcriptomes and translatomes, we found transcription and translation levels can not reflect protein abundance in most cases. From FGOs to the 4-cell embryos, the proteomes are predominated by FGO-produced proteins, while the transcriptome and the translatome are much more dynamic. FGO-originated proteins frequently persist in embryos after the corresponding transcripts are already downregulated or decayed. Improved concordance between protein and RNA is observed for genes starting translation only upon meiotic resumption or transcribed only in embryos, although the detected protein dynamics often lag behind transcription and translation. Concordance between protein and transcription/translation is associated with protein half-lives. Finally, a kinetic model well predicts protein dynamics when incorporating both the initial protein abundance in FGO and translation kinetics across developmental stages. In sum, our study reveals multilayer control of gene expression during oocyte maturation and embryogenesis.
