Oxidative stress. We have investigated the effect of the supplementation of diets with antioxidants. We have observed that supplementation with CoQ conferred antioxidant protection to the animals reducing also the expression of several antioxidant enzymes which confers to the animals a better redox balance in several tissues. These studies are carried out in animal models of neurodegenerative diseases.

Proteomics. We optimized various proteomic approaches for the study of adipose tissue and brain. The optimization of these techniques allow us to address several studies focused on identifying protein biomarkers associated pathologies originated in both tissues and especially the nervous tissue in neurodegenerative diseases.
