Marthe Gautier, découvreuse oubliée du chromosome de la trisomie 21

Marthe Gautier est à l’origine de la découverte du chromosome surnuméraire de la trisomie 21, anomalie génétique qui touche 50 000 personnes en France. À l’occasion de la Journée mondiale de la trisomie 21, retour sur le parcours de cette scientifique invisibilisée, avec la biologiste Julie Batut.

Let me post a spicy take here: most people don't read or cite other model organisms' work. Because of this, they keep rediscovering things and, most importantly, re-writing the timeline in favor of fewer and fewer models. That, plus an artificial limit of citations per paper equals this 🧪

Figure from the preprint showing sensory neuron morphology with different levels of Cas9 expression.

High levels of Cas9 are toxic in sensory neurons. Reducing Cas9 levels with uORFs avoids toxicity and is compatible with efficient editing. From @thompsonpeerlab.bsky.social. Fly lines @vdrc-flies.bsky.social

FlyBase needs your help! We ask that European labs continue to contribute to Cambridge, UK FlyBase, whereas US and other non-European labs can contribute to US FlyBase. For more information and how to donate: wiki.flybase.org/wiki/FlyBase...

thank you for all your efforts on behalf of the fly community!

A reminder you/your lab can support FlyBase at Cambridge through the following link. Every bit helps. Please share if you yourself can't donate.

Why a database of bug genes could be one of Trump’s most devastating cuts at Harvard FlyBase, the world's only fruit fly database, is in the crosshairs of Trump's attack on Harvard. Here's why it could matter for your health.

MassLive.com recently interviewed several Harvard FlyBase people and wrote this news article about the importance of FlyBase: tinyurl.com/4chpts9f

Images from the linked preprint showing Wingless stainings in the Drosophila wing imaginal disc. Targeting vps15 with two indepependent RNAi lines (paper also shows the same with a third line) does not result in a phenotype. In contrast, targeting vps15 with two independent sgRNA constructs and Cas9 results in strong accumulation of Wingless protein in perturbed cells.

Why use #CRISPR in #Drosophila when RNAi works so well? Because for some genes well is not good enough.

Check out new preprint from the lab demonstrating a role for Vps15 in Wingless trafficking. Something that was missed in several RNAi screens.

Tired of having to explain this again and again, I made an info- graphic of #Drosophila stock keeping. Any comments? @bdsc.bsky.social @flybase.bsky.social

"We should include eugenics in our undergraduate classes, reminding students that scientists must speak out when others lie about science and use it to further their political views," says professor @peiferlabunc.bsky.social.

A photo of a young Lilian Vaughan Morgan, sitting with a book on her lab staring into the distance.

A photo of an older Lilian Vaughan Morgan, sitting at a lab bench with a microscope and dozens of glass milk bottles bunged with cotton. Lilian is in the middle of applying ether to anaesthetize a bottle of flies.

This #InternationalWomensDay I want to tell the story of Lilian Vaughan Morgan. I learned of Lilian this past year - what a badass.

Lilian was a leading scientist when women weren't welcome in the lab, nor even the department. But she contributed immensely to the genetics of sex determination

We are thrilled to announce that IRL JEDI meetings will restart in 2025.
You can already register at flyjedi.sciencesconf.org where you'll find a preliminary program.
Looking forward to meeting you and restart this network of fly people!

Come with me as I troubleshoot this very high GC PCR toward clonable homology arms in an actinobacteria. Testing DMSO, Betaine 1M, and Propylene Glycol to see if we get amplification. Arms are 1000bp. Full length with arms and gene is 2800bp. Let's go!

Fresh off the press, our work on wing deployment in Drosophila 🪰:

Work by: Simon Hadjaje, Ignacio Andrade-Silva, Marie-Julie Dalbe and Raphaël Clément

"We report that numerous “miRNAs” previously reported in EMT and cancer contexts are not incorporated into RISC and are not capable of endogenously silencing target genes, despite the fact that hundreds of publications in the cancer field describe their roles"

www.biorxiv.org/content/10.1...

Our new preprint is out - please share!

We asked: How can we make CRISPR knockouts in vivo more efficient? And set up an assay that enables detection of CRISPR cutting with 100s-1000s of sgRNAs over entire chromosome arms in living animals.
