✨ ONLY 100 DAYS TILL #pint26! ✨
Pint of Science is happening 18-20 May 2026 in hundreds of cities worldwide!
We can't wait to explore the wonders of science with you! 🌍🔬

When people celebrate the individual genius of folks in science, they should also
mourn the collective loss of genius of folks who were actively discouraged or disadvantaged from a career in science because of the same person(s)

How do SMC complexes load onto DNA to get ready for loop extrusion?

@roisnehamelinf.bsky.social & co discovered that Wadjet, an SMC complex involved in bacterial DNA immunity, performs some impressive molecular gymnastics 🤸‍♂️🤸‍♂️🤸‍♂️.

Dynamic changes in chromosome and nuclear architecture during maturation of normal and ALS C9orf72 motor neurons We have investigated changes in chromosome conformation, nuclear organization, and transcription during differentiation and maturation of control and mutant motor neurons harboring hexanucleotide expa...

New work from my lab with the Brown lab on how genome folding changes during motor neuron maturation, and how this process goes awry in ALS motor neurons. Led by Dr. Ozgun Uyan.

Functional maps of a genomic locus reveal confinement of an enhancer by its target gene Genes are often activated by enhancers located at large genomic distances, and the importance of this positioning is poorly understood. By relocating promoter-reporter constructs into thousands of alt...

Our reporter hopping scaled up to thousands of integrations in a single locus, to produce high-resolution functional maps, with plenty of interesting insights: www.science.org/doi/10.1126/...

Congrats to all !

Synthetic engineering demonstrates that synergy among enhancers involves an increase in transcriptionally productive enhancer-gene contacts Enhancers are non-coding cis-regulatory elements that control the expression of distally located genes in a tissue- and time-specific manner. Recent studies indicate that enhancers can differ in their...

Excited to share the latest work from the lab led by @eharo84.bsky.social, in which we have used synthetic biology to explore the mechanisms by which different types of long-range enhancers ensure robust and precise developmental gene expression

RNA Pol II-based regulations of chromosome folding How transcription and cohesin complexes interact to regulate 3D genome organization remains unclear. Chapard et al. dissect their respective contributions and their interplay in shaping the genome arc...

Pleased to see this study out, combining experimental work from our lab at the @cbitoulouse.bsky.social, in particular by @nathaliebastie.bsky.social and @beckof.bsky.social, and from Laura Chaptal and @alengronne.bsky.social at IGH Montpellier

Congrats to all!

Two major events today on our campus!
🚴‍♀️First, the Tour de France is passing right next to us — @cnrsoccitanieest.bsky.social!
🧬Second, our latest paper on the role of G-quadruplexes (G4s) at promoters is now online at @natgenet.nature.com!

Predicting gene expression from DNA sequence using deep learning models Nature Reviews Genetics - Barbadilla-Martínez et al. review recent progress in deep-learning-based sequence-to-expression models, which predict gene expression levels solely from DNA sequence....

Together with the De Ridder lab www.deridderlab.nl we just published a review on deep learning as a tool for gene expression analysis/ prediction: rdcu.be/elQCc.

Low overlap of transcription factor DNA binding and regulatory targets - Nature A near-complete survey of transcription factor activities in Saccharomyces cerevisiae reveals that most transcription factors have both activator and repressor activities and limited overlap between t...

To the top of the "to-read" list. Looks like a heroic amount of work from the Hahn lab (large-scale ChEC-seq compendium!) www.nature.com/articles/s41...

Schematic illustrating the structural changes undergone by MukBEF SMC complex during DNA capture and ingestion.

How do SMC complexes capture DNA? 🧪

Led by Frank Bürmann, Jan Löwe’s & Mark Dillingham’s groups have identified the directional loading mechanism the bacterial SMC complex MukBEF uses to capture & ingest DNA, & found a phage inhibitor to this pathway.

Why is it so hard to rewrite a genome? Synthetic biologists have the know-how and ambition to retool whole genomes. But the hidden complexity of biological systems continues to surprise them.
