DR EVA ERZSEBET SZEGEZDI

M.Sc., Ph.D.

 
researcher
 

Biography

Affiliation: Lecturer in Biochemistry, NUI, Galway, Head of the Blood Cancer Biobank in Ireland, Principal investigator of the Cancer Niche Laboratory.  
Career information Dr. Szegezdi received her PhD in medical science in 2000 studying cell death signalling at the University of Debrecen, Hungary. She then joined the Cell Stress and Apoptosis Research laboratory led by Prof. Afshin Samali at the National University of Ireland, Galway in 2001 to study stress-induced cell death in heart and pancreatic cells. In 2010 she established her own research group as a Science Foundation Ireland Starting Investigator (SIRG) and an Irish Cancer Society Research Fellow focusing on how the tissues surrounding cancer cells protect the tumour from chemotherapeutics. She took up a university lecturer position in the Discipline of Biochemistry, National University of Ireland, Galway in 2011 where she is now a lecturer, the director of the Masters degree programme on cancer research and head of the Cancer Niche Research Laboratory and a principal investigator in the recently established Blood Cancer Network Ireland funded by SFI and the Irish Cancer Society.
Research and Clinical Interests: Current projects in her laboratory focus on the molecular wiring of cancer cells to predict how tumour cells respond to chemotherapeutics. A particularly interest of the laboratory is to understand the communication between the leukemia cells and the bone marrow tissue where leukemia cells reside in and how the bone marrow tissue makes the leukemic cells resistant to therapeutic drugs.

Research Interests

Mechanism of signal transduction in order to understand the driving forces of disease progression and to identify targets for therapy.

Identified that the pro-inflammatory cytokines interleukin-1b and interferon g act in synergy to induce beta-cell death and thus contribute to type I diabetes. Induction of nitric oxide synthase is necessary and sufficient to cause pancreatic beta cell apoptosis. Current in vivo studies assess the potential of IFNg neutralization to revert the progression of type I diabetes and promote pancreas recovery.

The potential of adult MSCs to repair ischemic heart damage was studied. The contribution of the components of ischemic conditions (hypoxia, nutrient deprivation, oxygen deprivation, inhibition of glues metabolism) to loss of cardiac muscle contractility and cell death was determined. Found that MSCs well tolerate the conditions which are damaging to cardiomyocyte function and survival. MSCs are able to retain functionality during prolonged ischemia by surviving on glycolytic energy production. Active glycolysis on the other hand provides an essential survival factor in MSCs and inhibition of glycolysis triggers rapid MSC death.

Regulation of apoptotic pathways in cancer cells and to the engineering of death ligands (TNF family of cytokines) for selective death receptor activation or receptor neutralization.

First demonstration that high affinity, receptor-selective variants of the death ligand, TRAIL, generated by computational design are more efficient death receptors activators and inducers of tumour cell death than wild type TRAIL. Found that the apoptosis-inducing potency of TRAIL is limited by its promiscuity, i.e. its ability to bind to four receptors due to formation of inactive heteromeric receptor complexes and fast kinetics of receptor activation is a key element in induction of apoptosis. Identified point mutations in TRAIL that provide receptor selectivity and thus enhance anti-tumour efficacy.

Current studies aim to develop a so called ratiometric analysis of protein expression. The working hypothesis is that rather than the absolute amount of a given protein, its amount relative to other proteins playing a role in a given biological process (i.e. the expression ratio of proteins) determines the biological response of a cell to any given stimulus.
