Gene regulatory network subcircuit controlling a dynamic spatial pattern of signaling in the sea urchin embryo [PDF]
We dissect the transcriptional regulatory relationships coordinating the dynamic expression patterns of two signaling genes, wnt8 and delta, which are central to specification of the sea urchin embryo endomesoderm.

Oct4 regulates DNA methyltransferase 1 transcription by direct binding of the regulatory element
Background The transcription factor Oct4 plays a pivotal role in the pre-implantation development of the mouse embryo. DNA methyltransferase 1 (Dnmt1) maintains the changes in DNA methylation during mammalian early embryonic development.

Highly efficient RNA-guided base editing in rabbit
Base editors can make targeted changes without inducing a double-stranded break. Here, the authors apply the BE3 and ABE7.10 systems to rabbit to create highly efficient targeted base substitutions and various mutation types, and show reduced frequency ...

YBX1 mediates alternative splicing and maternal mRNA decay during pre-implantation development
Background In mammals, maternal gene products decay and zygotic genome activation (ZGA) during maternal to zygotic transition (MZT) is critical for the early embryogenesis.
