Hot off the press! Delighted to share that our publication “Fat1 deletion promotes hybrid EMT state, tumour stemness and metastasis“, led by Ievgenia Pastushenko and Federico Mauri, from the lab of Cedric Blanpain (Laboratory of Stem Cells and Cancer, Université Libre de Bruxelles (ULB)) is now out in Nature. December 16, 2020. DOI: 10.1038/s41586-020-03046-1 | PMID: 33328637 |

This study shows that FAT1 acts as a tumour suppressor gene, its loss promoting initiation and malignant progression of skin and lung squamous cell carcinomas (SCCs). Through a combination of studies using mouse and human SCC models, this works not only uncovers key mechanisms by which FAT1 disruption promotes a hybrid EMT phenotype, with simultaneous acquisition of mesenchymal characteristics and maintenance of epithelial programs, but also identifies drug vulnerabilities and resistances of FAT1-deficient SCCs, the knowledge of which will be key for personalized medicine

Aix-Marseille University and our CNRS lab are progressively reopening after the Covid-19 lockdown. AMU has announced that we are officially allowed to welcome new interns to start in July. So if you are a student interested by a summer internship with us, we’ll be happy to have you around and offer you a safe environment to start practicing life as a scientist.  Contact me for details.

As a phase of renovations of the IBDM building has started (plan campus), we (half of the IBDM teams) just moved to our new temporary labs, in a lovely part of the Luminy campus, near the CINAM (the last rectangular building left to the CINAM buildings on the map below).
