Brief summary:
With as many as 14 million new cases each year and accounting for over 8.8 million deaths around the globe, cancer is considered to be one of the most threatening diseases. There is a prominent driving force to develop efficient workflows and tools for faster and more accurate diagnosis. Detecting cancer at its earliest stages often provides better prognosis for recovery. The state of each cell is assessed by the distribution and composition of proteins, lipids and nucleic acids in the cell interior, including the individual organelles. It is important to monitor both, the changes in the overall picture and changes based on specific molecules. It has been observed that certain epigenetic changes, such as DNA methylation, and metabolic alterations, can contribute to the development of cancer, and thus recognized as potential additional biomarkers for diagnosis. Metabolites such as succinate, fumarate and 2- hydroxyglutarate act as oncogenic signals (oncometabolites) and are therefore suggested to be used as biomarkers for monitoring cancer. Our goal is to investigate epigenetic and metabolic changes of melanoma cells (stage I-IV) and compare these with primary melanocytes and other cell types in skin (fibroblasts, keratinocytes). The surveillance of biomarkers is limited due to low reproducibility and accuracy of the monitoring methods. Surface-enhanced Raman Spectroscopy (SERS) allows the measurement of the current cell state and therefore serves to assess the effectiveness of a therapeutic treatment. SERS possesses the potential to investigate metabolic changes in single cells without additional labelling. It further enables the mapping of metabolic changes at the level of organelles, and the discovery of novel biomarkers. A systematic analysis of the sample application onto signal amplifying nanostructured material will be performed to optimize SERS for the biological systems. This project aims to contribute to two major fields of fundamental research: i) the implementation of innovative SERS materials in preventive cancer monitoring by identification of preferably universal biomarkers, and ii) the digitalization of the workflow and translation of high-level data acquisition into clinical routine for reliable data interpretation. Systematic data processing of the acquired spectra will allow the identification of spectral regions decisive for differentiation between the cell conditions. In summary, the analysis of the content of the main components (proteins, lipids, sugars, nucleic acids), oncometabolites and DNA methylation patterns using optimized SERS will provide a comprehensive picture of melanoma cells and is therefore a promising investigative tool that can assist diagnosis and treatment evaluation in cancer.
