Topics and objectives

Many diseases as well as aging are often associated with disturbances of amino acid/protein metabolism. This contributes to the occurrence of a catabolic state leading to muscle loss that worsens health and decreases the effectiveness of treatments. We are studying amino acid/protein homeostasis in order to understand the origins and consequences of these dysregulations. The ultimate goal is to develop nutritional and/or pharmacological strategies promoting the maintenance of amino acid homeostasis, focusing our research on the following points:

1) The characterization of the molecular mechanisms involved in the adaptive response to variations in amino acid availability; 2) the regulation of proteosynthesis and proteolysis in tissues; the inter-organ relationships in the use of amino acids.
