Research topics

The main research goal of our Laboratory is the study of simple and complex lipids in cellular and animal models and in humans, to determine the correlations between quali- and quantitative profiles, metabolism, structures and functions in physiological and pathological conditions.

Particularly, our researches are currently aimed at:
-     study the involvement of membrane lipids in cell proliferation and differentiation, signal transduction and chemoresistance in cancer;
-     analysis of fatty acid transport, metabolism and of molecular targets expression/activity in tumor cells;
-     evaluation of the functional role of lipids and their bioactive metabolites in chronic inflammatory diseases;
-     evaluation of the role of ω-3 PUFAs in human nutrition in healthy subjects and patients with chronic and/or degenerative diseases;
-     development of Functional Foods containing Nutraceuticals with antioxidant activity;
-     evaluation of inflammation and oxidative stress in biological fluids and experimental models;
-     Biochemistry applied to life sciences in space: evaluation of the effects of gravitational fields and cosmic radiation in human culture cells, in vertebrate and invertebrate animal models, and in humans, using simulation facilities (Random Positioning Machine, confinement isolation) and during real space flights (stratospheric balloons, FOTON, Shuttle, ISS).

 

Techniques

Techniques used in Laboratory are:
-    quali-quantitative analyses of lipid, amino acid and metabolic profiles in cell cultures, biological fluids and tissues by LC-MS, LC-ELSD, LC-UV, LC-FD and GC-FID;
-    determination of whole blood fatty acids using a DBS kit (Omega-3 test);
-   cultures of immortalized, stem and primary cells and treatments with enzymatic inhibitors, drugs, cosmetic products, nutraceuticals and liposomes;
-    cytotoxicity assays by MTT test and flow cytometry;
-    evaluation of oxidative stress and antioxidant activity of foods and nutraceuticals in cell cultures, tissues and biological fluids by enzymatic assays, ELISA and LC-UV;
-    subcellular fractionation and isolation / purification of membrane microdomains;
-    protein analysis by SDS-PAGE, western blotting, immunocyto/histochemistry in fluorescence, flow cytometry;
-    extraction, purification and analysis of nucleic acids: cloning and expression of genes in eukaryotic and prokaryotic cells, in vitromutagenesis techniques;
-    exposure to simulated microgravity (RPM) of in vitro and in vivo models and hardware tests for space missions.
