Molecular mechanisms of aging and related diseases. Aging is a complex and heterogeneous process. Among the multiple biological drivers of aging, the so-called “hallmarks of aging”, mitochondria have been long studied as relevant contributors. Since her PhD studies, Anna focused her research on mitochondrial structural and functional changes related to aging. Her research activities have been conducted on preclinical models and in the context of clinical studies through the use of biochemical and molecular biology methodologies that allowed her developing approaches to identify and quantify mutations affecting the mitochondrial genome.
Biomarkers of aging. According to the geroscience hypothesis, perturbations in the “hallmarks of aging”, increase the susceptibility to most chronic diseases, functional loss, and eventually death. Hence, these pathways may represent ideal targets for interventions to foster healthy aging. The collaboration with KI and other international Institutions has allowed developing innovative multi-marker strategies for the identification of biomarkers of aging also related to mitochondrial dysfunction in age-related conditions, including skeletal and cardiac muscle aging, frailty, inflamm-aging, and neurodegenerative diseases. This approach has been applied in several studies Anna has authored and co-authored.
