Raffaella Mastrocola has completed her PhD in the 2005 from the University of Torino, Italy. She experienced 10 years of research activity on diabetic complications holding different positions in several departments of the University of Torino. She has published 33 full-length research articles in peer reviewed international journals and has attended as presenter at several international conferences. She is serving as reviewer for reputed journals and as editorial board member of Journal of Diabetes Research.


The worldwide epidemic rise in metabolic disorders is tightly linked to excessive dietary intake of saturated fat and sugars. Although Advanced Glycation End-Products (AGEs) are toxic compounds well-known for their roles in type 1 diabetes complications, recent studies indicate their diet-induced accumulation in several dysmetabolic conditions, as obesity, insulin resistance, and type 2 diabetes. Consistently, we have recently reported in different animal models of diet-induced metabolic disorders the associative link between AGEs and the dysregulated activation of the lipogenic transcription factor SREBP1c. In particular, we have evidenced a double mechanism by which carboxy methyllysine (CML), the most studied AGE, interferes on SREBP1c activation by the direct glycation of its activating protein SCAP and by the reduction of the SREBP1c inhibitor SIRT-1. As consequence of SREBP1c overactivation, a marked lipid deposition was found in liver and skeletal muscle of mice fed high-fat and high-sugar diets. In addition, recent studies highlighted new transcriptional roles for SREBP1c in the development of cell damage and metabolic impairment. Specifically, we analyzed in different target tissues of dysmetabolism, as liver, skeletal muscle and brain, the effect of SREBP1c overactivation on selective pathways involved in the regulation of antioxidant and inflammatory response and structural and metabolic adaptation. Finally, our most recent findings evidenced that the inhibition of CML production by the administration of the anti-glycative compound pyridoxamine to mice fed a high-fructose diet was able to prevent both SREBP1c activation and SREBP1c-depending signaling impairment.
