New preprint from @anadopico.bsky.social (who I have had the great pleasure of supervising with Tom Milne) and our fantastic collaborators in the @davieslab.bsky.social www.biorxiv.org/content/10.6... #genomics #GeneRegulation #chromatin
A pictographic model of chromatin folding in the nucleus. DNA wrapped around nucleosomes aggregates into nanoscale domains, whilst newly nucleosome depleted DNA that forms after acute degradation of FACT projects from these domains and engages in long-range interactions that can span TAD boundaries

Excited to share that a part of my PhD work is online now on BioRxiv! www.biorxiv.org/content/10.6... We developed a genome editing approach to target the JAK2 V617F mutation and demonstrate its potential to alleviate MPN hallmarks in primary patient cells. Thread 👇

Fascinating paper on a number of levels… Anyone else think that NASA are basically saying that it’s likely that DNA/RNA/protein based life is likely to predate the solar system and arrived on earth on a comet… So there are likely to be DNA based life forms throughout the universe?

New lab preprint! ERCC6L2 disease is a recessive bone marrow failure syndrome caused by mutations in the putative DNA helicase ERCC6L2. Using mouse genetics, biochemistry and AF3 we uncover ERCC6L2-MRI as a KU-regulatory complex stimulating NHEJ at staggered DSBs: www.biorxiv.org/content/10.1...

Scientists have the most detailed view yet of how DNA folds and functions inside living cells! The breakthrough helps us understand how genetic differences lead to disease and opens up fresh routes for drug discovery 👇 shorturl.at/nQjsx @jojdavies.bsky.social @imm.ox.ac.uk @medsci.ox.ac.uk

Happy to share our latest publication, in which we show that the arrangement of nucleosomes around CTCF sites contributes to higher-order organisation of chromatin into TADs: www.embopress.org/doi/full/10....

Not from Tron or a psychedelic wallpaper. This exquisite pic reveals chromatin at base-pair resolution, captured by #ListerFellow James Davies and collaborators🤩 "For the first time, we can see how the genome's control switches are physically arranged inside cells." @jojdavies.bsky.social

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

New preprint with @gfudenberg.bsky.social We find the rate of cohesin loop extrusion in cells is set by NIPBL dosage and tunes many aspects of chromosome folding. This provides a molecular basis for NIPBL haploinsufficiency in humans. 🧵👇 www.biorxiv.org/content/10.1...
