Oxidative Stress and Thiol Redox Regulation


Our interests are above referred to oxidative stress, redox regulation in normal and tumoral cells. In particular, our studies are developed mitochondrial redox regulation especially in relation with glutathione and thioredoxin systems. Thioredoxin system- thioredoxin, thioredoxin reductase and peroxiredoxins-is analyzed also in relation to redox signalling. Inhibitors of thioredoxin reductase such as metal complexes are evaluated and consequently the redox state of the protein targets are investigated.

A second topic of interest is the role of antioxidant molecules in human nutrition.
