TL;DR
It is found that SP1 was indispensable for zygotic genome activation (ZGA) and the morula-to-blastocyst transition and plicamycin supplementation and microinjection of Sp1 siRNA showed this.
It is shown that disruption of C-terminal binding protein 1/2 activates both DUX-dependent minor ZGA-associated genes and DUX-independent major ZGA- and post-ZGA-associated programs.
In conclusion, pharmacological activation of the mTOR pathway did not positively influence TE differentiation in bovine embryos; however, it effectively rescued the unexpected negative effects induced by the vehicle on TE cell number and YAP1 signaling.
The results indicate that ascidians use a distinct set of transcription factors for ZGA, which resembles those of pioneer transcription factors that trigger zygotic genome activation (ZGA) in other animals, including flies and vertebrates.
It is shown that among the six Pcgf paralogs, Pcgf5, which is most prominently upregulated in 2CLCs and forms an MERVL-driven chimeric transcript (Pcgf5MT2C_Mm) during ZGA in 2-cell embryos, controls exit from the 2C-like state in mouse ESCs.
Type I PRMT-mediated ADMA is identified as an essential epigenetic regulator of early mammalian lineage specification and support a conserved ADMA–Hippo regulatory axis linking arginine methylation to embryonic cell fate decisions.
The link between decreased ZAR1/ZAR2 expression and abnormal epigenetic modifications in aged oocytes, as well as the relationship between human ZAR1 variants and oocyte maturation disorders and preimplantation embryonic developmental arrest, requires further validation through additional functional experiments and cli...
