Happy to share our new review in @annualreviews.bsky.social on abasic sites and their impact on DNA replication written by @angelotaglialatela.bsky.social. www.annualreviews.org/content/jour...
Thank you for highlighting our work!
It's a wrap! Thanks to all the organisers (@haicovanattikum.bsky.social, @titiasixma.bsky.social, @sylvie-noordermeer.bsky.social, @luijsterburglab.bsky.social, @thedownslab.bsky.social, and many others) for assembling this fantastic conference. One of the best meetings I have attended so far!
🎉 Congratulations to Steven Fesik and Neil Osheroff, who have been honored with 2026 awards from The Protein Society. Learn more about their prestigious awards 👉 www.proteinsociety.org/protein-soci...
Out today in @cp-molcell.bsky.social! We show that proximal polyadenylation site (pPAS) within MRE11 sustains its transcription through promoter–PAS chromatin looping. Congratulations to first author Kaimeng Huang, all co-authors and collaborators. www.sciencedirect.com/science/arti...
An in-press version of our latest paper in @natcomms.nature.com on phospho-activated protein-protein interactions with ssDNA-binding protein RPA during BIR. If your favorite pathway involves RPA, this may be for you! Thanks to the lab, collaborators & @ukri.org! www.nature.com/articles/s41...
Excited to share our new review in Molecular Cell on replicative single-stranded DNA gaps and their role in genome instability and cancer therapy. #DNARepair #ReplicationStress #GenomeStability #CancerResearch #MolecularBiology #PARPinhibitors​​​​​​​​​​​​​​​​ www.cell.com/molecular-ce...
Great to see this team effort out, in which we find a new player in genome stability and a neurodevelopmental disease caused by its loss. Fantastic collaboration with @drjhujh.bsky.social and @profstewartlab.bsky.social alongside @sorenhough.bsky.social and friends in @spjacksongroup.bsky.social.
Happy holiday, everyone! 2026 Social DNAing Schedule is now online. Here is a sneak peek. Check it out and sign up at www.cancer.columbia.edu/research/pro...
Thrilled to share our latest work - now available in full in Nature Communications - led in my lab by @vcherdy.bsky.social, with key collaborative contributions from @nitikataneja.bsky.social . rdcu.be/eVrxX

MRE11 proximal polyadenylation site-mediated looping impacts transcription and genomic stability
Replicative single-stranded DNA gaps arise when DNA synthesis proceeds past lesions or difficult-to-replicate regions. This review delineates the pathways that generate, stabilize, and process these i...

1. A new @cp-molcell.bsky.social paper from @chowdhurylab.bsky.social that shows proximal polyadenylation site (pPAS) within MRE11 sustains its transcription through promoter–PAS chromatin looping. ACS supported this work through Dr. Ke Cong's postdoc fellowship. doi.org/10.1016/j.mo...
It is almost over, so this seems to be a good time to share a few photos taken during the DNA repair meeting in Egmond aan Zee (mostly in the early mornings before sessions). What a fantastic setting to hold a conference!
