Excited to share our latest paper, out today @CellCellPress. We found that large pieces of the human genome can transfer between cells upon direct contact, endowing recipient cells with heritable phenotypic changes. (1/7) cell.com/cell/fulltext/S0092…

Excited to share our new Nature study! 🧬 We (@UruciSidrit et al) discovered that CFAP20 helps clear stalled RNAPII, preventing harmful co-directional clashes with DNA replication machinery. This protects cells from R-loops and genome instability. nature.com/articles/s41586-0…

Our latest paper has just been published in Cell! doi.org/10.1016/j.cell.2025.… We developed a new method called MCC ultra, which allows 3D chromatin structure to be visualised with a 1 base pair pixel size.

Another exciting research article from a member of the #RepliFate network! The @altmeyerlab identified the CNOT1-CCR4-NOT complex as a multi-level suppressor of the 53BP1-p53-p21 signaling axis. Check out their findings here: doi.org/10.1016/j.celrep.202…
