- Reposted by Duxin lab'Just bypass it: mechanisms of DNA damage tolerance' takes a fresh look at how cells replicate damaged DNA. The review, by RepliFate-affiliated @duxinlab.bsky.social (@bric-ucph.bsky.social, @ucph.bsky.social), revisits lesion bypass in light of recent advances DOI: 10.1016/j.tibs.2025.07.004

- Reposted by Duxin labWhat makes #cshldnarep special isn’t just the cutting-edge, top-notch science; it’s the chance to meet the authors of the papers we build on every day, exchange ideas, and feel part of this community. Heading home exhausted, grateful, full of ideas and renewed motivation to push my project forward!
- Our PhD student @martaolivasantiago.bsky.social and postdoc @amitash.bsky.social presented their posters on #cshldnarep, turning data into an insightful dialogue. Huge thanks to everyone who stopped by our poster!
- This week we’re at CSHL #cshldnarep where the DNA replication & genome maintenance community has gathered for a week of science, discussions, and late-night brainstorming.
- Reposted by Duxin labSometimes DNA replication hits a 🛑 roadblock. Cells don’t stop; they take clever detours (DNA damage tolerance) 🚗💨 to keep genomes intact. That’s the focus of our new review in @cp-trendsbiochem.bsky.social: “Just bypass it: mechanisms of DNA damage tolerance” 🔗 doi.org/10.1016/j.ti...

- It is not always safe to repair DNA Damage. Sometimes, cells "just bypass it". During DNA replication, repair of lesions on DNA can be dangerous. Cells instead "tolerate" DNA damage and focus on finishing replication. Read our review and find out why and how: doi.org/10.1016/j.ti...
- Reposted by Duxin labJust published! Lecona (@emlecona.bsky.social ) & Méndez #RepliFate labs show that VCP/p97 removes Pol α/primase from chromatin to avoid excess ATR activation during normal #DNAreplication VCP/p97 = checkpoint gatekeeper! Read the full study: doi.org/10.1038/s414...

- Reposted by Duxin labFrogs in the lab? Yep! 🐸 This week, RepliFate PhD students are diving into the Xenopus egg extract system at the @duxinlab.bsky.social (@bric-ucph.bsky.social, @ucph.bsky.social) -where test tubes meet frog magic to unravel the mysteries of DNA replication and genome integrity.
- Our lab’s a little more crowded (and a lot more curious) this week! 🧠🐸 We’re thrilled to welcome @RepliFate students for a hands-on course in Xenopus egg extracts. They're diving into the Xenopus world and learning how this powerful system helps us explore DNA replication and genome stability.
- 🎯 A tenure-track group leader position in translational cancer research is now open at Finsen Laboratory. Come join an excellent and friendly research environment combining both the Rigshospitalet and the KU @ucph.bsky.social affiliated groups candidate.hr-manager.net/ApplicationI...
- Chromosome Biology Club is back today! Join us for two exciting talks: 🧬 Christian Nielsen (CCS/ICMM) on the distinct roles of condensins I & II in mitotic chromosome mechanics 🧬 Judit Pilmark (BRIC) on mutational signatures linked to NER deficiency Starting at 4.45 pm Followed by pizzas and beer

- Reposted by Duxin labthis week 20 years ago, Nature published two seminal papers showing for the first time that BRCA-mutant cells were selectively sensitive to PARP inhibitors, paving the way for clinical trials and approval of PARP inhibitors for patients with BRCA-mutant ovarian and breast cancers, and beyond.
