Scientific Activity

She entered the research group of Cellular Bioenergetics of the Department of Medicine of the University of Udine in 1991. Her main research interest focuses on mitochondrial bioenergetics in different cell models resuming physiological or pathological conditions.
The most recent research topics concern:
• oxidative damage in different cell models, with particular regard to energy metabolism and its implication in cellular cytotoxicity (apoptosis);
• role of ATPsynthase in ischemic and pharmacological preconditioning of myocardium;
• biochemical mechanisms of mitochondrial biogenesis in relation to in vitro differentiation of myoblasts, with particular regard to the definition of the functional/structural state of mitochondrial ATP synthase and its isoform expressed in the plasma membrane;
• mitochondrial biogenesis and function in different models of skeletal muscle plasticity in relation to stress conditions (endurance, bed-rest, ageing) and in some movement pathologies.

Her research activity has been published as works in extenso (most of which in international journals or monographs) as well as communications and proceedings in many national and international congresses.
