Do not miss this incredible paper from David Fernandez Antoran's team (with some contribution from my team). The paper introduces epithelioids as a powerful 3D culture system for 8 different human tissues, for longitudinal in vitro studies of human epithelia. Great thread from David below.

🚨#Preprint alert! @antoranlab.bsky.social in close collaboration with @imartincorena.bsky.social lab www.biorxiv.org/content/10.6... How can we study human #epithelial tissues for months in the lab, while preserving their native structures and behaviour but without passaging?

Our autoimmunity paper is out today in final form and OA. We found a fascinating landscape of somatic evolution underpinning thyroid autoimmunity, where tens of B cell clones convergently lose immune checkpoints and some acquire 4-6 drivers over years of evolution. www.nature.com/articles/s41...

Polyclonal selection of immune checkpoint mutations in thyroid autoimmunity - Nature

Single-molecule DNA sequencing identifies recurrent somatic mutations in autoimmune B cells that may allow them to escape peripheral tolerance and cause autoimmune disease.

Excited to share our latest work in Nature. Applying single-molecule and single-cell DNA sequencing methods, we uncover an extraordinary landscape of somatic mutations in immune checkpoint genes in autoimmune B cells, suggesting that somatic mutations may be key to autoimmunity [1/n] rdcu.be/fdqbr

How could a simple self-replicating system emerge at the origins of life? RNA polymerase ribozymes can replicate RNA, but existing ones are so large that their self-replication seems impossible. Could they be smaller? Excited to share our latest work in @science.org on a new small polymerase. 1/n

A small polymerase ribozyme that can synthesize itself and its complementary strand

The emergence of a chemical system capable of self-replication and evolution is a critical event in the origin of life. RNA polymerase ribozymes can replicate RNA, but their large size and structural ...

A short thread. For years, I have been surprised by how much confusion our discovery of clones carrying cancer-driver mutations in normal tissues has caused in the cancer community. Typical questions like: (1) if you see these mutations in normal cells, are they really cancer drivers?... [1/4]

Our latest work is out in Nature today. In this paper, we introduce an improved version of NanoSeq, a duplex sequencing protocol with <5 errors per billion bp in single DNA molecules, and use it to study the somatic mutation landscape of oral epithelium in >1000 people www.nature.com/articles/s41...

The stomach is an organ unique in its function, environment and exposures. How does this affect the mutations that normal cells in the stomach acquire? What does this reveal about the origins of stomach cancer? These questions and more in our @nature.com paper: www.nature.com/articles/s41...

A nice article covering some of the surprises in the field of somatic mosaicism in the last decade. As I say there: "Judging by the discoveries that we are making at the moment, the journey has only just started. I expect many surprises in the next few years." knowablemagazine.org/content/arti...

We are all mosaics

Picture your body: It’s a collection of cells carrying thousands of genetic mistakes accrued over a lifetime — many harmless, some bad, and at least a few that may be good for you.

Excited to share a major breakthrough from the lab! D&D-seq is a new technology that bridges a key gap in single-cell multi-omics/genomics : the ability to map DNA:Protein interactions (e.g., TFs or chromatin remodellers). Led by Ivan Raimondi, Wei-Yu Chi and Sang-Ho Yoon

🧬 We’re excited to introduce D&D-seq, a single-cell technology that maps DNA:Protein interactions through molecular footprinting. Check it out here: biorxiv.org/content/10.1... #Genomics #Epigenetics

Resharing here a recent X post. In this preprint, we introduce an improved version of NanoSeq, a duplex sequencing protocol with <5 errors per billion bp in single DNA molecules, and use it to study the somatic mutation landscape of oral epithelium in >1000 people. 1/ www.medrxiv.org/content/10.1...

Somatic mutation and selection at epidemiological scale

As we age, many tissues become colonised by microscopic clones carrying somatic driver mutations ([1][1]–[10][2]. Some of these clones represent a first step towards cancer whereas others may contribu...
