Цел на проекта

Mitochondria are double-membrane organelles that sustain the bioenergetic metabolism of cells by producing ATP at the level of the cristae, convoluted folds of the inner membrane. ATP production efficiency and mitochondrial morphology, including cristae architecture, are tightly linked. Consequently, by being coupled to mitochondrial function, the reshaping of mitochondria across spatial scales regulates the cellular bioenergetic and metabolic states. Mechanical stimuli have recently been shown to modulate cellular metabolism, thus impacting physiological (e.g. cell migration, proliferation, death) and pathological (e.g. cancer progression) processes. Mechanical forces are able to reshape the global morphology of mitochondria. However, cristae remodelling upon mechanical stimuli has not yet been unravelled, and it remains unknown whether mitochondria are the key regulators of bioenergetic mechanometabolism. In Mito-MechaMet project I aim to unveil how force-induced changes in mitochondrial cristae architecture (Aim1) modulate cellular bioenergetic metabolism (Aim2) via nanoscale reorganization of proteins regulating mitochondrial shape (Aim3). These ambitious objectives will be achieved by bringing together my experience and skills on mitochondria imaging, the expertise of the host laboratory (G Giannone lab, CNRS, Bordeaux) on mechanobiology and super-resolution, and the know-how of collaborators regarding mitochondrial metabolism (BioDynaMit lab, CNRS, Bordeaux). Mito-MechaMet results will impact several fields ranging from biophysics and biomechanics to cellular biology, especially cancer biology, where mechanical cues in the tumor microenvironment critically regulate mitochondria dynamics and cancer progression. Altogether, the Mito-MechaMet project represents a uniquely tailored opportunity for me to master the necessary skills, experience and independence to pursue my long-term aspiration of leading an independent lab investigating mitochondrial biomechanics.
