The actin cortex acts as a mechanical memory of morphology in confined migrating cells - Nature Physics Cells often navigate through confined spaces. Now it is shown that cells retain a mechanical memory of previous confinement events, which makes them more efficient at migrating through narrow microenv...

Excited to share our new publication in Nature Physics about the mechanical memory of morphology in confined migrating cells by @kyohalie.bsky.social 🥳

Super fun collab with @davidbrueckner.bsky.social and @gcharras.bsky.social 👏🏻

Enjoy the reading www.nature.com/articles/s41...

I have some BIG NEWS to share today!

Today I begin my next adventure as

Chief Editor of Nature Biomedical Engineering!!

(a thread) @natmethods.nature.com @natbiomedeng.nature.com @natureportfolio.nature.com

I'm so sorry. Could you confirm if the heating is switched on 😉

Wow

Are you looking for a postdoc?
I will be looking for 2-4 people after the summer to join the lab !!
Do not hesitate to reach out and disseminate !!

1/ Beyond thrilled to see my #PhD work now published in @jcb.org
A short thread (🧵) for #metastasis #metabolism #ExtracellularVesicles (EVs) aficionados

@gounismichalis.bsky.social‬ et al. show that cells that seed early lung #metastasis in #BreastCancer have altered #metabolism. These metabolic alterations lead them to release extracellular vesicles which engender a microenvironment conducive to invasive growth. rupress.org/jcb/article/...

Dynamic regulation of integrin β1 phosphorylation supports invasion of breast cancer cells - Nature Cell Biology Conway et al. show that integrin β1 phosphorylation is regulated through balanced activities of tyrosine kinases, such as Src and Arg, and phosphatases, such as PTP-PEST and Shp2, facilitating invadop...

Latest from @ivaskalab.bsky.social @jrwconway.bsky.social in NCB. We find that SHP-2 inhibition stops TNBC invasion and limits metastasis by blocking integrin dephosphorylation!

New paper from @ivaskalab.bsky.social out now! 🍾 Watch how cancer cell adhesion dynamics are disrupted by inhibiting the phosphatase Shp2 - key to integrin β1 phosphorylation. Blocking Shp2 impairs adhesion and reduces invasion potential. 🎥👇 Read more at: www.nature.com/articles/s41...

Our newest paper is out in NCB. @jrwconway.bsky.social‬ designed a new FRET reporter, Illusia, to show the importance of integrin β1 phosphorylation dynamics in 3D invasion! Video: TNBC cells expressing Illusia with a Src (Saracatinib) or SHP2 (SHP099) inhibitor. www.nature.com/articles/s41...

Amazing news! Warm congratulations to @johannaivaska.bsky.social for the award. Super proud!
