Graphical Abstract
The research activity concerns the study of the molecular mechanisms that regulate cell cycle, signal transduction and cell growth, with a focus on energetic metabolism and its dysfunctions linked to human diseases. The main topics of research are:
1) The effects of plant-derived bioactive compounds on aging and protein aggregation responsible for neurodegeneration.
2) Serine metabolism as sex-specific hallmarks of Alzheimer’s disease and during astrocyte differentiation
3) The role of Snf1/AMPK in the regulation of metabolism and TORC1 pathway in response to nutrients.

Research interest
Mechanisms regulating metabolism, signaling and cycle cycle; the role of nutrition to prevent diseases; how functional foods and bioactive compounds regulate the molecular pathways governing cellular aging and neurodegeneration.
Research areas
Coccetti’s research activity concerns the study of the molecular mechanisms which regulate signal transduction, cell cycle progression and metabolism by using the budding yeast Saccharomyces cerevisiae as a model organism of eukaryotic systems. In recent years, the study has focused mainly on the effects of specific amino acids on intracellular metabolism, mitochondrial functionality as well as cellular proliferation.
New drugs with anti-proliferative activity on colorectal cancer were also studied in the last few years. A series of novel synthesized molecules, deriving from resveratrol, were evaluated for G2/M cell cycle arrest and inhibition of tubulin polymerization. The antitumor and apoptotic activities were studied both in vitro cultures and in a mouse xenograft model of colorectal cancer, opening the route to a new class of potential therapeutic agents.
Currently, the research activity is focused on the study of the role of nutrition to prevent diseases and to reach a healthy aging. Since food has long been considered an important key to promoting well-being and preventing disease, this line of research is aimed at better understanding the molecular mechanisms that underlie healthy nutrition. Specific legumes, fungi and purified bioactive components from these edible matrices are actually under study to investigate their effect on the specific pathways which regulate cellular aging and neurodegeneration both in unicellular and pluricellular organisms.
