On-site event
Presidentti auditorium, BioCity
Assoc. Prof. Sirio Dupont, University of Padova, Italy
Mitochondrial fission coordinates the tranional and metabolic response to forces
Host: Johanna Ivaska (johanna.ivaska@utu.fi)
Coffee and sandwich at 11:45, first come first served!
Six PhD researchers and early-career postdocs are welcome to have a lunch in restaurant Mauno and discuss with Assoc. Prof. Dupont after the seminar. This is a great possibility to learn hosting skills in friendly environment and create connections for future. Everyone is welcome to join, BioCity Turku will offer the lunch.

Dupont lab is interested in understanding how the mechanical properties of the extracellular matrix (ECM) regulate signaling pathways, gene tranion and other cellular processes, and how this is relevant for cell behavior, tissue homeostasis and disease. Their goal is to identify novel general principles in vitro, and to push their validation in vivo with the development of new animal models to study mechano-signaling in tissues. Dupont lab uses a multidisciplinary approach that includes custom-built compliant cell culture substrata, ECM micropatterning, cell micromanipulations, optical microscopy, molecular and cell biology techniques, tranional and bioinformatic analyses, proteomics, metabolomics, CRISPR/Cas9 modified cell lines, and genetically-modified mice, also thanks to multiple collaborations with colleagues in Italy and abroad. Dupont lab has identified YAP/TAZ tranional coactivators as readers of ECM mechanical cues and mediators of their effects on cancer cell proliferation and mesenchymal stem cell differentiation, and are now developing genetic tools to study the relevance of F-actin remodeling as regulator of YAP/TAZ activity in vivo. Moreover, they got recently interested in understanding how mechanical cues, YAP/TAZ and metabolism are reciprocally regulated.
