The goal of this project is to investigate the impact of chelators with the ability to inhibit tyrosine kinases on key cellular processes. This project focuses on one of the most aggressive cancer, glioblastoma multiforme (GBM). The epidermal growth factor receptor (EGFR) belongs to the receptor tyrosine kinases (RTKs) family. The presence of mutations in the EGFR region results in increased proliferation and resistance to therapy with older generation of the tyrosine kinase inhibitors (TKIs). One of the most common mutation in the extracellular domain of the EGFR receptor is EGFR variant III (EGFRvIII), characteristic of GBM. It is also worth mentioning that the current knowledge of GBM has many gaps in understanding the origin of the tumor, its heterogeneity and the specificity of the surrounding tissues. Therefore, in the current project, we plan to perform experiments on patient-derived cell lines and 3D spheroid models that reflect the actual tumor conditions. GBM therapy faces the problem of the insufficient drug penetration through the blood-brain barrier. Currently, only osimertinib is a third-generation EGFR inhibitor that penetrates the blood-brain barrier. Iron metabolism is closely related to the EGFR pathway, which seems to be particularly important in the development of GBM. Based on our previous experience, we designed novel multi-targeted drugs (named FeTKIs) by combining iron (Fe) chelation functionality with tyrosine kinase inhibition (TKI). FeTKIs are novel osimertinib analogs with the potential to inhibit EGFR and the ability to bind iron ions. We suggest that this approach will impact several molecular targets and aspects of GBM treatment.
In this project, the PhD student will perform the following research tasks:
- investigation of the cellular response to the incubation with FeTKIs, which are characterized by good metal ion chelating ability, EGFR inhibition and sufficient penetration of the blood-brain barrier
- testing the specificity of FeTKIs against EGRFvIII mutation
- comparison of the results obtained on commercially available cell lines with cells derived from patients (studies on traditional monolayer cultures and 3D spheroids)
- MSc diploma in biotechnology, biology, biophysics, medical physics, medicinal chemistry or related science.
- Knowledge of the basic cell biology and human genetics and molecular biology.
- Experience in cell culture, PCR, RT-qPCR, ELISA, flow cytometry or Western Blot is welcome.
- Good written and oral communication skills in English.
- High motivation to conduct scientific research and ability to work in a team.
- Scientific achievements, especially papers published in science journals and conference presentations will be an additional asset.
- Motivation list with a description of the scientific interests
- List of scientific publications
- Copy of the MSc diploma
- Recommendation opinion from current supervisor
