Sir, you can’t break up with someone who already blocked your number

At the very least, hiring great scientists who also happen to be phenomenal people.

In this mess of a world, arriving to an office like this, stealthily set up by your incredible lab members (@karenyaacoub.bsky.social and Sheryn Suchet), not only makes you feel warm inside but also reassures you that you must be doing something kind of right.

Here is a copy of last year's Twitter thread explaining our preprint - jump to (21) for the new stuff πŸ‘€

Synergy between cis-regulatory elements can render cohesin dispensable for distal enhancer function

now revised and journal accepted at www.science.org/doi/10.1126/...

I am happy, excited and very humbled to have obtained an ERC starting grant to study the interplay betweeen nuclear pores and chromatin organization! Keep posted for job advertisements and pretty microscopy pictures ;-)

β€œOur findings suggest the existence of tens of thousands of enhancers that remain undiscovered by currently available chromatin data, underscoring the continued need for expanding resources for enhancer discovery.”
Great paper and very important finding - many congrats Axel & team! πŸ‘πŸ‘

Amazing work by @charleneboumendil.bsky.social and her team addressing the crucial role of nuclear pores in chromatin organization. A highly recommended read!

OK, this is wild.

In September 2023, geophysicists across the world started monitoring a very odd signal coming from the ground under them.

It was picked up in the Arctic. And Antarctica. It was detected everywhere, every 90 seconds, as regular as a metronome, for *nine days*.

What the HELL?

Redirecting

By definition, enhancers can activate from a distance. But with increased distance between enhancer and promoter, the activation drops. To study this systematically, we build a synthetic locus: www.cell.com/molecular-ce... 1/12

Hi Bluesky! I made a 3D chromatin starter pack.
Let me know if you would like to be added.

In this review @gracebower.bsky.social & I discuss recent evidence showing that, unlike canonical enhancers, long-range enhancers located hundreds of kb from their targets rely on additional mechanisms to ensure robust gene activation during mammal development. www.sciencedirect.com/science/arti...

Schematic overview of the proposed mode of action of the newly discovered REX element. Top: An enhancer can activate a gene at a short distance, but not at at long range. Middle: Presence of (C/T)AATTA motifs within an enhancer enable it to act over long distances. Bottom: Coupling a short-range enhancer to the REX element containing the same motifs turns it into a long-range enhancer.

REX - a mammalian "range extender" element that can turn short-distance enhancers into long-distance enhancers.

New preprint from a collaboration led by Grace Bower and Evgeny Kvon.

Hi all, just to say thanks for all the enthusiasm about the #epigenetics, Chromatin and Gene Regulation starter pack. The interface is a bit unreliable so a few people I added got missed off 😬. If you notice this applies to you, just message me and I'll try again. go.bsky.app/TKp9YAn

2 great labs having drinks in a bar in sunny Montpellier

Just finished hosting @PengyiYang82 and lab members for an amazing week @IGH_MTP filled with learning about scMultiomics, brainstorming and maybe a drink or 3. So proud to see how far we've come since our postdocs in @Jothi_Lab 🍻
