Dipeptidylpeptidáza IV v ortotopických modelech gliomu / Dipeptidyl peptidase IV in orthotopic models of glioma

Malignant gliomas belong to a highly aggressive class of tumours. Average patient survival time generally does not exceed 15 months. Despite intensive research, no therapeutic strategies capable of significantly extending the lives of those affected by the disease have been established to date. One potentially viable area of research into possible therapeutic targets in cancer therapy focuses on cell surface proteases. This group of proteins includes dipeptidyl peptidase IV (DPP-IV). Changes to DPP-IV expression have been established in the case of various cancer types including malignant gliomas. Understanding the role of DPP-IV in the biological processes of this malignant disease may thus contribute to the development of new therapeutic modalities. This thesis is therefore dedicated to establishing an orthotopic xenograft model as well as a genetically engineered model (GEM) of the glioma. The effects of DPP-IV on the growth of an experimental glioma were subsequently examined, as was the ratio of catalytic and non- catalytic mechanisms in this process. The GEM model was used for monitoring enzymatic activity and DPP-IV distribution. Non-invasive fluorescence imaging was employed in order to monitor the intraexperimental dynamics of experimental gliomas. The results indicated that DPP-IV...
