Last 5th-10th May was held the 2019 Gordon Research Conference on “Fibronectin, Integrins and Related Molecules” where Pere Roca-Cusachs from IBEC and Antoine Khalil from UMCU presented talks discussing Mechanocontrol results on how mechanical signals and the extracellular matrix regulate cell responses and tumour invasion. During the keynote session titled “Mechanisms and Mechanics of Integrin ECM Connections” Pere Roca-Cusachs gave a talk on “Exploring the Substrate Dependence of Integrin-Mediated Mechanotransduction”. Antoine gave an oral presentation where he described how cell-ECM adhesion regulates the positioning of basal cells and their specification into invasive leader cells during collective invasion of breast cancer organoids.
The Gordon Research Conference was held in Lucca, Italy and is the premier international conference for academic, government and industry scientists interested in understanding how integrins and the extracellular matrix regulate virtually every aspect of cell and tissue function. The program of the conference reflected the interdisciplinary nature of the integrin and extracellular matrix field, spanning different areas of biology from inflammation to mechanobiology, cell migration, stem cells, development, and cancer. During the meeting unpublished data was highlighted and stimulated active discussion among all participants.
The application period opens today until the 8th May 2019, where you can submint an abstract if you are interested in giving a short talk during the summer school.
The application does not guarantee acceptance to the Summer School due to the limited number of participants, an email with the resolution of the applicaton process will be sent on June 15th 2019.
The summer school will be held in La Cerdanya at the Eco-Resort located in Prullans in the Catalan Pyrenees.
The participation fee is 300€ (taxes not included) and includes accomodation in shared double room (from 17th-20th September 2019), full-board, workshops and conferences, leisure activities and shuttle bus from Barcelona to the venue.
A review article by Antoine A. Khalil and Johan de Rooij from UMC Utrecht have appeared in the Experimental Cell Research section of Elsevier
Collective invasion drives the spread of multicellular cancer groups, into the normal tissue surrounding several epithelial tumors. Collective invasion recapitulates various aspects of the multicellular organization and collective migration that take place during normal development and repair. Collective migration starts with the specification of leader cells in which a polarized, migratory phenotype is established.
Leader cells initiate and organize the migration of follower cells, to allow the group of cells to move as a cohesive and polarized unit. Leader-follower specification is essential for coordinated and directional collective movement. Forces exerted by cohesive cells represent key signals that dictate multicellular coordination and directionality. Physical forces originate from the contraction of the actomyosin cytoskeleton, which is linked between cells via cadherin-based cell-cell junctions.
The cadherin complex senses and transduces fluctuations in forces into biochemical signals that regulate processes like cell proliferation, motility and polarity. With cadherin junctions being maintained in most collective movements the cadherin complex is ideally positioned to integrate mechanical information into the organization of collective cell migration. Here we discuss the potential roles of cadherin mechanotransduction in the diverse aspects of leader versus follower cell specification during collective migration and neoplastic invasion.
