Dr Ugun-Klusek’s research focuses on investigating the biochemical and molecular events that drive neurodegeneration and currently she is exploring the role of Monoamine oxidases (MAOs) in this process. MAOs are mitochondrial enzymes that play a key role in maintaining neurotransmitter levels in the brain but also important in redox homeostasis because they generate reactive oxygen species (ROS) as a catalytic by-product. ROS can chemically modify proteins and alter their biological functions. If not cleared, oxidatively damaged proteins may become cytotoxic. Neurons are particularly vulnerable to ROS and mitochondrial dysfunction due to their high energy demand. Dr Ugun-Klusek’s current research is focusing on investigating the effect of MAO-A generated ROS on mitochondrial health and protein degradation signalling in the context of neurodegeneration. The long-term aim is to identify molecular pathways that control mitochondrial function and neuronal health/survival.
Dr Ugun-Klusek also interested in investigating the role of MAO-A in other pathological conditions such as cancers and the application of proteomics techniques to study disease mechanisms.
Opportunities arise to carry out postgraduate research towards an MPhil / PhD in the areas identified above. Further information may be obtained on the NTU Research Degrees website https://www.ntu.ac.uk/research/research-degrees-at-ntu.
