Research Program. Precision Nutrition and Aging

Metabolic Syndrome Group

Group leader: Dr. Pablo José Fernández Marcos

Objectives: Our group is devoted to the development of nutritional interventions reproducing short-term fasting benefits in metabolic syndrome, cancer and other age-related pathologies, and to the study of the molecular mechanisms underlying these interventions. These are our main lines of research:

• Identification, characterization and development of new bioactive products that reproduce molecular features of short-term fasting: inhibition of the insulin signaling pathway, reversible depolarization of mitochondria or increased levels of the important redox metabolites NAD+ or NADPH.
•Study the molecular mechanisms underlying the beneficial effects of short-term fasting during chemotherapy treatment: reduction of chemotherapy toxicity and induction of anti-tumor immune reaction.
• Study the role of the fasting-induced sirtuin members Sirt1 and Sirt3 in lung and liver cancer development, respectively.

Dr. Pablo José Fernández Marcos

Group leader of the Metabolic Syndrome Group

Dr. Pablo José Fernández Marcos studied Biochemistry in the Universidad Autónoma de Madrid. He obtained his PhD in the laboratory of Dr. Manuel Serrano, at the CNIO, for which he obtained the Special PhD Award and published 8 research articles about mouse models of cancer, metabolism and aging in mice.

He then moved to the laboratory of Prof. Johan Auwerx, at the EPFL, Switzerland, studying mouse models of metabolic alterations and achieving 5 publications. He returned to the CNIO after two years at the EPFL, where he combined studies on cancer with research on metabolism, publishing 9 new articles. In December 2015, he was appointed Group leader Metabolic Syndrome Group at IMDEA Food, focused on nutritional interventions against obesity, diabetes and cancer.

From this standpoint, Dr. Fernández Marcos has participated in several publications about the potential of bioactive products and fasting to improve metabolic status and to enhance chemotherapy safety and efficacy. In total, he counts with 38 publications in prestigious journals as Science, Cell, Cancer Cell, Cell Metabolism, Journal of Clinical Investigations, Nature Communications, PNAS or EMBO Journal, 9 of them as corresponding author (already from IMDEA Food) and 15 as first author
