Delighted to have our work on 🧬 resilience to 🩸cancer led by @g-agarwal.bsky.social & amazing collaborators, including @kharaslab.bsky.social, published in @science.org: www.science.org/doi/10.1126/... 🧵

New @science.org today Discovery of a genomic variant that protects against blood cancer by reducing risk of CHIP (blood stem cell mutation clones, common with aging) @bloodgenes.bsky.social @kharaslab.bsky.social science.org/doi/10.1126/...

Rest in peace. We need to develop better treatments for so many individuals impacted by 🩸 and other cancers!

Enjoyed writing this commentary with @g-agarwal.bsky.social for @bloodjournal.bsky.social: ashpublications.org/blood/articl... Covers an exciting paper from Tapper and co: ashpublications.org/blood/articl... #mpnsm

Happy to highlight an essay I wrote together with @marcdemanuel.bsky.social, @natanaels.bsky.social and Anastasia Stolyarova, trying to think through what sets the mutation rate of a cell type in an animal species: www.biorxiv.org/content/10.6... 1/n

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 👇

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...

How did the devastation of the atomic bombings 80 years ago ultimately help give rise to bone marrow transplantation and modern #stemcell biology? Our historical commentary with Jonas Gudera in @natcellbio.nature.com explores these unappreciated connections: www.nature.com/articles/s41...

In this Nature Medicine paper, we draw from our experiences in evaluating and implementing #genomics in Australia, Canada, England, Hong Kong and the US www.nature.com/articles/s41...

Massive single-cell study by Kanai et al (www.medrxiv.org/content/10.1...): - Once statistical power is high, constrained genes have more (though weaker) eQTLs. - Chromatin-QTLs near constrained genes have "normal" effect sizes, colocalize more with disease, but exhibit attenuated peak-gene effects.

Grateful to Isabella Alves & @cterminiphd.bsky.social for writing this fantastic N&V in @natcellbio.nature.com: www.nature.com/articles/s41... Nicely covers our 📰 led by della Volpe & co: www.nature.com/articles/s41...
