The aim of this project is to analyze the kinase dependent signal transduction in head & neck cancer to identify tumor specific changes and changes induced by different therapy modalities such as X-rays. Therefore, we analyze established HNSCC cell lines and primary tumor tissue using classical biochemical methods, translational approaches such as tissue micro arrays as well as cutting-edge technologies like differential proteomics and functional kinome profiling (see also below UCCH Kinomics Core Facility). By understanding the signal transduction and biology of HNSCC we aim to use selected kinase inhibitors for individualized therapy approaches. A special focus is on the combination of specific targeting strategies with X-rays to induce radiosensitization.

Signal transduction in HNSCC: From kinome profiling to molecular targeting. (A) Human primary normal tissue and tumor samples (B, C) can be analyzed using functional kinome profiling (see below). (D) Recent studies identified kinases of the Src-family (SFK) to be frequently upregulated in HNSCC. (E) SFK hyperactivity (increased SFK-autophosphorylation) is associated with worth prognosis in advanced HNSCC. (F) Increased SFK-autophosphorylation can also be detected in some HNSCC cell lines using Western blot (G) while inhibition of SFK prior irradiation sensitizes HNSCC cells with increased basal SFK-activity towards X-rays (radiosensitization).

This project focuses on Glioblastoma Multiforme (GBM), which is an aggressive primary brain tumor, characterized by rapid progression and oncogene activation. One common and frequently expressed oncogene in GBM is the constitutively activated epidermal growth factor receptor deletion mutant EGFRvIII. EGFRvIII represents a typical oncoprotein that activates different signaling pathways altering thereby multiple cellular processes. Therefore, analyzing how EGFRvIII impacts therapy relevant processes like DNA repair, replication, transcription and cellular signaling are the main research interests. By understanding these complex processes, we hope to identify specific and new targeting approaches to individualize GBM therapy and to finally form the molecular rationale to improve overall survival.

EGFRvIII expression is associated with increased replication stress and R-loop accumulation: (A) EGFRvIII-/+ model system: EGFRvIII+ cells show an activated replication stress response and (B) increased endogenous DNA damage as indicated by elevated γH2AX-foci. (C) Increased expression and phosphorylation of replication stress markers in EGFRvIII+ areas of GBM samples displaying heterogeneous EGFRvIII expression. (D) Increased transcription rate in EGFRvIII+ cells as measured by EU-incorporation. (E) EGFRvIII+ cells show elevated levels of R-loops compared to isogenetic EGFRvIII- cells

This project is part of the graduate school "Innovative Technologies in Cancer Diagnostics and Therapy" which starts in October 2020.

Glioblastoma (GBM) is one of the most common and aggressive brain tumours. GBM is treated by means of resection, radiotherapy and temozolomide (TMZ). However, there are great differences in the response to the various treatment modalities, although the mechanisms are largely unknown, especially with regard to radiation sensitivity. The primary aim is to identify patterns in the methylom and kinome of GBM cells associated with radiation and TMZ sensitivity. Both basal and radiation- or TMZ-induced patterns will be analysed. Furthermore, the patterns of resistance and sensitivity will be tested on patient material and compared with the response to therapy.

This project started in August 2020. The aim of this project is to identify responder and non-responder to immune checkpoint inhibition (ICI) to guide further therapy of head and neck squamous cell carcinoma (HNSCC) patients.

Immune checkpoint inhibitors have already been approved as 1st and 2nd line therapy of relapsed or distant metastatic head and neck squamous cell carcinoma (R/M-HNSCC). However, only 13-18% respond to therapy with no definitive predictive markers available resulting in a great need to establish predictive tests identifying responding and non-responding patients.

For ICI therapy of advanced malignant melanoma and non small cell lung carcinoma it has been demonstrated, that specific kinase activity clusters of peripheral blood mononuclear cells (PBMC) can be predictive. These clusters result from functional kinome profiling and might be promising in R/M-HNSCC. To test this, liquid biopsies will be collected from HNSCC patients before and under ICI treatment. PBMC will be isolated and functional kinome profiling will be performed. After cluster analysis the kinase activity clusters of the PBMC will be compared with the survival data of the patients.

This method may also allow to monitor the patients` individual response during ICI treatment enabling the early detection of a progresses. Such a predictive test would support to identify responding versus non-responding patients and to guide non-responders to a more appropriate therapy. This would also enable a more efficient economical use of the expensive therapeutics.

In the future, such predictive test may also be transferred to additional entities.

The UCCH Kinomics Core Facilitiy offers functional kinome profiling using a PamStation®12 from PamGene Int. (The Netherlands). The PamTechnology is a microarray-based system which consists PamChips® holding peptides specific for either serine/threonine (STK Chips) or tyrosine kinases (PTK Chips). Sequence specific phosphorylation of the peptides by the kinases within a lysate firstly provides information on the overall kinase activity (A). Subsequent bioinformatic prediction methods (so-called upstream kinase analyses, Bionavigator software) identify the most prominent kinases (B). The technique deduces the activity of the majority of the approx. 500 kinases within the human kinome.

Kinome profiling using the PamGene's microarray assay. (A) The PamGene's microarray assay for kinase activity profiling is based on measuring peptide phosphorylation by protein kinases. The PamChip® disposable consists of 4 identical arrays, each array containing up to 144 (STK) or 196 (PTK) peptides immobilized on a porous ceramic membrane. The peptide sequences (13 amino acids long) harbor phosphorylation sites derived from literature or computational predictions and are correlated with one or multiple upstream kinases. Fluorescently labelled anti-phospho antibodies are used to detect phosphorylation activity of kinases present in the sample. (C) During the assay, the sample solution is pumped through the porous membrane, allowing for faster kinetics and real-time measurements. Images are taken for each array at several exposure times by the CCD camera in the workstation. (BD) Images can later used by the BioNavigator® software to generate heat maps and upstream kinase prediction. The data workflow consistis of image quantification, quality control, statistical analysis, visualization and interpretation.
