Mechano-metabolism on the rise
Sirio Dupont
Abstract
Cells respond to the physical and geometrical tissue properties by multiple mechanotransduction mechanisms that can profoundly influence cells' decision-making, extending to cell metabolism. This review incorporates the most recent findings on this topic, organized along the idea that the mechano-metabolic connection serves three main functions, namely to inform systemic metabolism on the general functioning of a tissue/organ, to tune cells' energy production with the mechanical requirements imposed by their surroundings, and to coordinate cell metabolism with cell fate choices induced in response to mechanical cues. This connection highlights the pervasive influence of mechanical cues on cell activity, opens interesting questions on its physiological and pathological roles, and lays the foundations for exploiting the mechano-metabolism axis to design new therapeutic approaches.
