💫NEW: Saur, Lesage et al. report that RNA:DNA hybrids arise at double-strand breaks in transcribed genes, independently of de novo recruitment of RNA polymerase II/III, as a result of DSB-induced transcriptional repression. @lablegube.bsky.social @cbitoulouse.bsky.social bit.ly/4kFWGr1

Excited to share our lab’s latest preprint! We identify DDIAS as a novel single-stranded DNA-binding component of the TOPBP1–CIP2A complex, which acts in a mitotic DNA damage response pathway to protect chromosome integrity. Short summary below, and read it here: www.biorxiv.org/content/10.1...

New from us in @natrevmcb.nature.com -- @szmyd-radoslaw.bsky.social & @radoncdocgee.bsky.social explore how DNA repair actively shapes cancer cell fate following DNA damage, reframing repair as both a protective process & a driver of treatment response and cell death. www.nature.com/articles/s41...

Sharing our latest work tracking DNA damage inheritance by Live+QIBC www.nature.com/articles/s41.... Huge congrats to @apanagopoulos.bsky.social, M. Stout and all co-authors for this tour de force! Beautifully summarized by @s-j-aitken.bsky.social & E. Reilly www.nature.com/articles/d41...

Excited to share our new paper on Nature - how Ku accommodates Alu expansion in primates by binding to dsRNA, providing a clue for both the high levels of Ku and its essentiality in human cells. Thank @chaolinzhang @hchung03 @LenaSteckelberg More to come www.nature.com/articles/s41...

Happy to share yet another story back from my days as a postdoc 👇 we uncovered how the J2 antibody specifically recognizes #dsRNA. J2 is a quintessential tool used to discover #RNA, QC #RNA therapeutics and much more

We describe how to perform Oligo-seq, a new method to map DNA motifs targeted by base editors. Validated with APOBEC3A and APOBEC3B, but adaptable to AID, CRISPR-Cas9, and more. 🧬 Full protocol 👉 www.sciencedirect.com/science/arti... Thanks to @buissonlab.bsky.social at @ucirvine.bsky.social!

Check out our new pre-print! 🦠🧬🦠🧬🦠 We used a FACS-based CRISPR-Cas9 screening method that exploits translation levels as a readout and identified PACT as a key inhibitor (not an activator!) of PKR during RNA viral infections. @buissonlab.bsky.social www.biorxiv.org/content/10.1...

We’ve been using phase lock tubes to streamline phenol-chloroform extractions. Unfortunately they’ve been discontinued everywhere we’ve looked. We recently tried Molykote (vacuum grease with intermediate density compared to aqueous and organic phases) with great results. Also much cheaper.

New Lab Preprint! We show that ATR inhibition results in hyperactivation of PARP1 at replication forks, driven by APOBEC3B, UNG2, and APE1 reaction cascade targeting unprotected single-stranded DNA at the forks. www.biorxiv.org/content/10.1...

🧬 I'm happy to announce that our latest study, "ATR safeguards replication forks against APOBEC3B-induced toxic PARP1 trapping," is now available on bioRxiv! 🧬 Check it out here: biorxiv.org/content/10.1... @buissonlab.bsky.social
