1/n Have you ever wondered whether an amplified oncogene in a patientβs tumor (HER2/EGFR/CCND1/β¦) is carried on extrachromosomal DNA (ecDNA) vs embedded within a chromosome? Bulk WGS + genome graph can hint, but in practice itβs often hard to resolve. Here is our new preprint.

Most genetic interaction studies measure gene relationships in one condition, but environment can reshape which genes depend on each other.
Today in Molecular Cell, Luke Gilbert & team deliver the first systematic, multi-condition map of genetic rewiring in human cells.

PAF15βPCNA exhaustion governs the strand-specific control of DNA replication
Nature - PCNAβPAF15 has a key role in determining replisome dynamics during genome replication and protecting against genome instability.
Dear Colleagues,
Delighted to share that our first lab paper is now published in Nature.!!! πππ
We identify a previously concealed βsafety limitβ in DNA replication program: cells intrinsically rate-limit PCNA via PAF15, shaping strand-specific and global replication dynamics.

We (sidrituruci.bsky.social et al) discovered that CFAP20 helps clear stalled RNAPII, preventing harmful clashes with DNA replication machinery. This protects cells from R-loops and genome instability.
