Scientific summary

My main research field concerns energy fluxes in cardiac and skeletal muscle cells on a physiological basis starting from the subcellular compartments to the integrated animal models and human. We have been deeply involved in researching the role of the creatine kinase system in cellular energy transfer, and demonstrating intracellular compartmentation of energy fluxes through enzyme-enzyme interactions or direct energy crosstalk between organelles in cardiac and skeletal muscles. We have demonstrated the direct energetic interactions between mitochondria and other organelles like sarcoplasmic reticulum and myofilaments and their alterations in heart failure. We are studying alterations in energy metabolism in heart failure using functional biochemical and molecular approaches. We have shown a down-regulation of the transcriptional pathway of mitochondrial biogenesis in pathological cardiac and skeletal muscle cells. We are the studying signaling pathways involved in the control of muscle energy metabolism including AMPK, sirtuins, thyroid hormones etc... We investigate the relevance of metabolic therapy by resveratrol and exercise in heart failure.
