Project abstract: 

Modern nuclear magnetic resonance methods will be developed for molecule-based experiments in chemistry and biochemistry, with the aim of translation to the clinic. The proposed methods are centered on metabolic biomarkers, especially molecules related to oxidative stress. Their observation by magnetic resonance will be optimized in vitro and in cells to monitor the impact of therapy on metabolism. Magnetic resonance experiments carried out on healthy, tumorous and immune cells within a short time window – on the order of tens of hours - following treatment using drugs or radiation will enable the evaluation of the efficacy and the toxicity of specific therapies. When translated to non-invasive clinical MRI, the proposed biomarkers will be able to yield crucial information on disease evolution in real time, thus allowing treatment optimization.

 

O1. In vitro observation of enzyme kinetics relevant to metabolites related to oxidative metabolic processes: GSH/GSSG turnover, free-radical production with adapted spin traps and scavenging.

O2. Methods to adapt NMR observation time window to kinetics relevant to the transformation of metabolic substrates such as glucose, glutamine, VitC, GSH, creatine, and choline.

O3. Combined NMR and biological methods for metabolic follow-up in cancer and immune cells.

O4. Assessment of treatment effects on cancer and immune cell metabolism.
