- Reposted by Christof Gebhardt(1/n) Excited to present the latest work from the de Wit lab, where we identify and characterise loop extrusion-mediated fountains in mammalian genomes using acute depletion of 3D genome regulators: doi.org/10.1093/nar/.... A Bluetorial🧵:
- The review on live-cell SMT that I contribute to the jmolbiol.bsky.social special issue ‚Imaging of the central dogma‘ is now online as pre-proof: www.sciencedirect.com/science/arti...
- In the review, I give an overview of important steps along the implementation, execution, and analysis of single-molecule tracking in living cells and multicellular organisms. This includes a summary of labeling approaches,
- Reposted by Christof GebhardtThis is a piece that I and @karsten-rippe.bsky.social discussing a lot, and a topic that is very close to my heart. The editors @naturerevgenet.bsky.social gave us the stage to do so, and the final version of our review is now available under this link: rdcu.be/erP1u A short thread follows 1/n

- Reposted by Christof GebhardtGreat to see this published @genesdev.bsky.social. Evidence that enhancers can activate a bystander gene in an adjacent TAD, and that cohesin facilitates this. @uoe-igc.bsky.social. pubmed.ncbi.nlm.nih.gov/40436628/
- Reposted by Christof Gebhardt1/ Super excited to share my first preprint from @andersshansen.bsky.social Lab! We used MINFLUX to track chromatin (H2B-Halo and Fbn2 locus) at an unprecedented 200 μs, then combined it with SPT to span μs-minutes (H2B) or SPT & Super-Res Live-Cell Imaging (SRLCI) to span μs-hours (Fbn2)

- Reposted by Christof GebhardtProgram is out for our first EMBL #singlemolecule gene regulation meeting! Check out the dedicated panel sessions on single molecule genomics, single molecule imaging and theory where we would like to brainstorm the future of the field: Registration is open! 👇 www.embl.org/about/info/c...
- Single molecules, in living zebrafish embryos, during hour-long period of development: Jonas' work on binding kinetics of cohesin and CTCF around ZGA now online. Great collab with labs of @lucagiorgetti.bsky.social @akispapantonis.bsky.social doi.org/10.1038/s414...
- Search gets faster, binding longer, bound fraction of cohesin and CTCF goes up, especially at and after ZGA
- Reposted by Christof Gebhardt#Cellpose 3 paper now out. Not all images are perfect. Restore your images with Cellpose3 to get better segmentations, w/ @marius10p.bsky.social www.nature.com/articles/s41...
- Reposted by Christof GebhardtOur new review on how the #chromatin domain is formed in the cell is now available @Curr Opin Struct Biol.📄✨ We critically discuss the domain formation mechanism from a physical perspective, including #phase-separation and #condensation. 📥 Free-download link: authors.elsevier.com/a/1keGn,LqAr...
- Reposted by Christof GebhardtAfter a long journey, Segment Anything for Microscopy is now published in Nature Methods! We significantly improve SAM for interactive and automatic segmentation in light and electron microscopy and build a user-friendly tool. www.nature.com/articles/s41...

- Reposted by Christof Gebhardt1/n Excited to share our new preprint! Using live imaging in Drosophila embryos, we show that RNA Pol II clusters switch from sites of initiation to elongation during zygotic genome activation and that they are stably associated with an active gene: www.biorxiv.org/content/10.1...
- Great work and very useful developments!
- Making intrabodies from antibodies just got easier! Learn how we made 𝟭𝟵 intrabodies to bind and light up peptides and histone modifications in live cells. And thanks to Academia, all sequences are freely available. (video credit: Yuko Sato @YukoSatoT2) (1/15) www.biorxiv.org/content/10.1...

- Happy to share Duyen's and Philipp's work on effective binding energy landscape and affinity of RBPJ obtained in vivo by on- and off-rate measurements is now published. Great collaboration with labs of Franz Oswald and Tilman Borggrefe doi.org/10.1038/s414...
