Dataset Summary
TitlePreimplantation mouse embryo proteome during 8C to 16C division
DescriptionPreimplantation stages of mouse embryo development involve temporal and spatial specification and segregation of three late blastocyst cell lineages; trophectoderm (TE), primitive endoderm (PrE) and epiblast (EPI). Spatial separation of the outer TE lineage from the two inner-cell-mass (ICM) lineages (PrE and EPI) starts with the 8- to 16-cell transition and concludes following transit through the 16- to 32-cell stages. This results in a nascent early blastocyst ICM derived from descendants of primary founding inner cells and a secondarily contributed population; of which subsequent relative EPI versus PrE potencies are subject to debate. We showed that generation of primary but not the secondary ICM populations is highly dependent on temporally discreet activation of the mammalian target of rapamycin (mTOR – specifically mTORC1) around 8-cell stage M-phase entry. Moreover, that this role is mediated via the regulated function of the 7-methylguanosine- (7mG) cap binding initiation complex (EIF4F) and potentiating the translation of a subset of key but otherwise intransigent mRNAs containing 5’ UTR terminal oligopyrimidine (TOP-) sequence motifs. To find out translation of which mRNAs is regulated by mTOR during 8- to 16-cell transition, we analysed proteomes of control and mTOR-inhibited embryos during this time window.
