Tumor cell in the maze of the lung vasculature in a mouse.
A #research team investigated how the mechanical properties of tumor cells influence their metastatic pathway.
🔑 🔍: Viscosity – rather than elasticity – determines how tumor cells invade surrounding tissue.

New study finds cancer spread driven by how “thick” tumour cells are
🧬 New study in Nature finds cancer spread depends on how “thick” tumour cells are. Higher cell viscosity helps them survive blood flow and escape into new tissues - a key step in metastasis. 🔬 www.nature.com/artic... #CancerResearch #Science #Health

Pour former des métastases, les cellules cancéreuses doivent franchir une course d’obstacles qui exige des propriétés physiques spécifiques. Une étude montre que leur viscosité joue un rôle crucial, mais pas à toutes les étapes de la progression métastatique.

👩🔬 👨🔬 Who ?
This study has been initiated many years back in the lab when we realized, as many in the field, that CTCs can also get "stuck" in vessels. It was mostly driven by Valentin Gensbittel, whose wizardy was shaped by many members in the lab (and outside), including @naelosmani.bsky.social
📊 In summary : mechanically adaptable tumor cells are most likely to complete the metastatic cascade

2️⃣ Once arrested, they perform better during #extravasation, by endoctrinating
the endothelium ⚙️ The more viscous, the better
3️⃣ Once extravasated, disseminated cells with low viscosity were better at initiating metastatic outgrowth ⚙️ The more viscous, the better
🔬 What have we found ?
In a nutshell, we show that #tumor #cell #viscosity acts as a rheostat of multiple important steps of hashtag#metastasis.
1️⃣ Circulating tumor cells exploit their viscous properties to reach mechanically-constraining capillaries ⚙️ The less viscous, the better
💡 Have you ever wondered how #circulating #tumor cells squeeze through narrow #capillaries during hashtag#metastasis ?

What ? We successfully developed and validated isoform-specific intrabodies targeting Ral oncoproteins. Some of them successfully perturb RalA-specific functions in cells and offer a promising therapeutic strategy for significantly suppressing tumor growth and metastasis in vivo.
