Congratulations to @groth-anja.bsky.social on receiving the Novo Nordisk Foundation Jacobæus Prize 🏆 we’re proud to see Anja's mentorship, leadership, & pioneering work in epigenetic cell memory getting top recognition 👏 celebrating the contributions of past & present lab members to this work too 🥳

Congratulations Susi! Great work and I am happy to see it out! Hope to see you soon to say cheers together 🥳!

Our latest collaboration with the talented Susi @sbantele.bsky.social and Jiri Lukas is out now @science.org 🤩. We reveal the hidden price for DNA repair, with potential implications for genome function, gene therapy and ageing👇

Repair of DNA double-strand breaks leaves heritable impairment to genome function Upon DNA breakage, a genomic locus undergoes alterations in three-dimensional chromatin architecture to facilitate signaling and repair. Although cells possess mechanisms to repair damaged DNA, it is ...

We don't find that they are susceptible to disrupted histone recycling. There is no correlation between gene length and changes in gene expression in our recycling mutants.

Thank you so much Jenny!

Excited to share my main postdoctoral work and our new insights into epigenome inheritance! Huge thanks to an amazing team—especially Alva Biran (@biranalva.bsky.social) & Anja Groth (@groth-anja.bsky.social). 🧵👇
