inally, we demonstrate that PAS‑mediated promoter looping broadly regulates DDR gene expression and genome stability, expanding the conceptual framework for how DDR factors are controlled.

Deletion of the MRE11 pPAS reduces MRN complex abundance and phenocopies hypomorphic MRE11 defects. We further find that loss of the pPAS triggers ectopic DNA replication and confluence‑induced cell death, revealing non‑canonical, non‑DDR functions linked to MRE11.

MRE11 proximal polyadenylation site-mediated looping impacts transcription and genomic stability Alternative polyadenylation (APA) generates transcript isoforms with variable 3′ untranslated regions (UTR) lengths, yet its role in DNA damage respon…

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.

Pharmacologic interrogation of USP28 cellular function in p53 signaling Bratt, Kilgas et al. describe the SAR-driven design of CAS-010, a selective USP28 probe, alongside a control compound and an inhibitor-resistant mutant. They show that USP28 inhibition mimics p53 path...

Excited to share our new paper from the Buhrlage lab & Chowdhury labs! 🎉 We designed CAS-010, a selective, low nanomolar USP28 inhibitor that reduces p53 transcriptional activity, mimics p53 loss & disrupts 53BP1-USP28 binding, offering new insights into USP28 function.

Thank you!

CTC1-STN1-TEN1 controls DNA break repair pathway choice via DNA end resection blockade Antagonistic activities of the 53BP1 axis and the tumor suppressor BRCA1-BARD1 determine whether DNA double-strand breaks (DSBs) are repaired by end joining or homologous recombination. We show that t...

Excited to share our latest publication, out in @science.org! We define a key role for the CST complex in double-strand break repair pathway choice. This study was conducted in close collaboration with the Sung lab at UT Health San Antonio. Congrats to @michelleswift.bsky.social and all authors!
