How and when embryonic gene activity begins following fertilization are unknown. In a paper just published in Cell Reports (https://doi.org/10.1016/j.celrep.2023.112023), we report a high-resolution time-course that reveals a transcription programme initiating within four hours of fertilization in mouse one-cell embryos. We refer to this programme as immediate embryonic genome activation, or iEGA. The iEGA programme predicts embryonic and cancer-associated pathway expression: regulators predicted by iEGA are also predicted by gene expression in human one-cell embryos, and inhibiting them in the mouse quickly blocks transcription and embryonic development. We hope that parallels between embryos and cancer could in the future be exploited to close gaps in our understanding of both.

In an Opinion piece just published in Trends in Cell Biology ('The initiation of mammalian embryonic transcription: to begin at the beginning': https://doi.org/10.1016/j.tcb.2022.08.008), Tony describes a model to account for the onset of embryonic transcription based on the lab's work on human one-cell embryos. The initiation of gene activity in embryos has parallels to cancer, and the model proposes that the origin of many cancers is epigenetic and recapitulates the initiation of embryogenesis by fertilisation.
