Frank A.E. Kruyt obtained his PhD in the field of developmental biology at the Hubrecht Laboratory in Utrecht, the Netherlands (Prof. dr. S.W. de Laat/dr. P.T. van der Saag). His postdoctoral research was dedicated to the study of bone marrow failure and cancer prone disorder Fanconi Anemia (FA), cloning new FA genes and elucidating their function, at the VU University in Amsterdam, the Netherlands(with Prof. dr. H. Joenje) and Baylor College of Medicine, Houston, Tx, USA (with Prof. dr. H. Youssoufian). Intrigued by cancer biology and therapy he entered the field of oncology, exploring the possibility of using the FA pathway and apoptosis as targets for cancer therapy at the department of Medical Oncology at the VUMC, Amsterdam, the Netherlands. Currently, as professor in the field of Experimental Oncology at the department of Medical Oncology, UMCG, Groningen, his group is continuing work on targeting cell death regulatory mechanisms and stress responses in cancer. Importantly, recognizing tumor cell heterogeneity, the role and mechanisms of tumor cell differentiation (CSC and EMT) in tumor aggressiveness and targeted therapy are being studied with a focus on aggressive brain tumors (glioblastoma) and lung cancer. He has obtained funding amongst others from the Netherlands Organization for Scientific Research (MWO), Dutch Cancer Society (KWF) and Top Institute Pharma (TIPharma). He is editorial board member of Biochemical Pharmacology and Apoptosis and review editor of Frontiers in Molecular and Cellular Oncology.
1. Targeted therapy: Cell death and ER stress
The selective activation of programmed cell death or apoptosis in cancer cells is one of the main objectives in this research line. Particularly, mechanisms of TRAIL receptor signaling are examined in order to optimize clinical benefit of TRAIL receptor agonists in lung cancer. ER stress/the unfolded protein response (UPR) and autophagy are also important for maintaining cellular homeostasis and survival. Underlying mechanisms and therapeutic value are examined in glioblastoma (stem cell) models.
2. Cancer stem cells and Epithelial-Mesenchymal Transition (EMT): novel therapeutic opportunities
The tumor microenvironment (TME) plays a major role in the development and progression of cancer. This not only includes cancer prone conditions such as shortage in nutrients and oxygen, but also the active secretion of pro-tumorigenic growth factors/cytokines from normal cells like fibroblasts, immune cells and endothelial cells within or surrounding the tumor. In my group, we study the effect of the TME on cancer stem cells (CSC) and differentiation status of tumor cells, including epithelial-to-mesenchymal transition (EMT), known to determine tumor growth and invasive/metastatic activity as well as resistance to therapy. Identified mechanisms are explored for use as new targets for therapy.
