👇 Highlights below
H3K4 methylation-promoted transcriptional memory ensures faithful zygotic genome activation and embryonic development
In the life of a vertebrate embryo, gene expression is initiated for the first time at zygotic genome activation (ZGA). Maternally expressed transcription factors present in the embryo are essential f...

🚀 PREPRINT ALERT!

🐸 Research led by our PI @evahoermanseder.bsky.social reveals H3K4 methylation as an epigenetic memory in Xenopus embryos, vital for zygotic genome activation & development.

👏 Congratulations @meghana-oak.bsky.social & rest of authors.

Looking forward to a great discussion!
My colleague Meghana @meghana-oak.bsky.social will present her work this Thursday at THE virtual Maternal Zygotic Transition symposium!

We are very excited about this opportunity! You can follow her talk by registering here:

Next Wed 12.02. at 6pm CET I will be speaking about our latest preprint: www.biorxiv.org/content/10.1... and present our findings on how we developed a machine learning model that identified new reprogramming barriers, such as H3K27ac, and our in vivo experiments to test it. See you there!

Highlights and key findings from our study in the thread below 👇
Digital Reprogramming Decodes Epigenetic Barriers of Cell Fate Changes
Fates of differentiated cells in our body can be induced to change by nuclear reprogramming. In this way, cells valuable for therapeutic purposes and disease modeling can be produced. However, the eff...
