Dr Kaidonis is a Post-doctoral Scientist at the Victor Chang Cardiac Research Institute. She is dedicated to understanding cardiac biology in two key areas: (i) the role of adrenergic signaling in the heart's response to pathological (eg. myocardial infarction and hypertension) and physiological (eg. exercise and the 'fight or flight' response) stress and (ii) changing biochemical pathways involved in cardiomyocyte maturation.

Elucidating the cardioprotective role of the α1A-adrenergic receptor

The α1A-adrenergic receptor (α1A-AR) protects cardiomyocytes from catacholamine-mediated damage in the failing heart. However, it is not known whether α1A-ARs also play a role in cardioprotection when the heart is challenged with a physiological stress, such as occurs during the ‘fight or flight’ response. This area of research is important to understanding how the heart has evolved to facilitate the survival of the fittest.


Understanding metabolomic changes during cardiac development

The ability of the heart to repair after injury is lost as the heart grows and matures. Our investigation into developmental changes to cardiac metabolites may provide insights into pathways that can be targeted so that regeneration can be enhanced after cardiac injury in adults. We have used mass spectrometry at key developmental time points to identify these metabolic changes.
