Our work on NPC biogenesis is now out! Wanlu Zhang investigated the role of FG-Nups in NPC reassembly, pore dilation, and the nuclear envelope remodelling using acute depletions, correlative EM, and MINFLUX imaging 💫.
Thanks, Wanlu and all the collaborators!

Thanks Aleksander, also for your paper link!

This seems like a really important paper comparing chromosome tracing methods, demonstrating that classical denaturing DNA-FISH and chromosome tracing leads to substantial distortion of 3D genome structure, likely due to the high-temperatures involved (70-90C):

Thank you very much, Takashi!

Mitotic chromosomes form through long, overlapping and self-repelling DNA loops, generated by the Condensin complexes!

Check out our newest paper here, and see below for a short Bluetorial!

Did you know that DNA must form overlapping loops to give rise to the well-known X-shape of chromosomes? 🧬🧪

New research from EMBL's Ellenberg Group provides new insights into the process of chromosome formation.

EMBL scientists have shown how overlapping loops of DNA stack upon each other in dividing cells to give rise to rod-shaped chromosomes

Our new findings on how chromosomes get ready for cell division are now published in @cellpress.bsky.social!

Congratulations, Kai, @andibrunner.bsky.social and everyone else involved! 🤩

We are #hiring!

We have two open postdoc/research scientist positions to join our #ERC funded project MITOFOLD to resolve the organization of mitotic chromosomes!

1) experimental biologist shorturl.at/LjGEM
2) data scientist shorturl.at/nDdhQ
Please share! 🙌

We look forward to your application! 🤩

Congratulations to @andibrunner.bsky.social
and the team, and many thanks to the lab of Jan-Michael Peters for support!

We found that the interphase and mitotic chromatin loop organization have more in common than previously thought:

In both stages big loops are built first, small ones second
jcb.org
@andibrunner.bsky.social et al. @ellenberglab.bsky.social show that interphase organization into Cohesin-driven loops occurs in a sequential and hierarchical manner - just like the mitotic organization by Condensins. https://buff.ly/426gIEu

My first own project is published:

Despite major differences in chromosome shape during #interphase and #mitosis, the underlying #loop-extruder based organization is highly similar

A new data resource and new insights into human chromatin biology! 🧬🥳

Our excellent postdoc Wanlu Zhang is at #CellBio24 and will talk about her unpublished NPC biogensis work tomorrow!

Check it out and say hello 🙌🏼
