Maternal O‐GlcNAc Transferase Is Required for the Asymmetry of Epigenetic Modifications in Mouse Zygotes

The FASEB Journal, Volume 40, Issue 4, 28 February 2026.
OGT inhibition during in vitro oocyte maturation disrupts epigenetic asymmetry in the zygote. It reduces male pronuclear size and eliminates DNA methylation asymmetry by decreasing H3K9me2‐mediated 5mC protection in the female pronucleus and suppressing TET3‐dependent DNA demethylation in the male pronucleus.
