Cell interactions in tumour microenvironment as a new tool for therapy response prediction in head and neck cancer
Tumour microenvironment (TME) can activate protecting signalling pathways in tumour cells, especially when TME cells are damaged by chemotherapy. In this project, we will focus on cisplatin resistance conferred to cancer cells by TME. FaDu cells will be co-cultured with primary cell lines derived from tumour tissue of individual head and neck cancer (HNSCC) patients. Effect of co-culture on resistance, invasiveness, and migratory capacity of cancer cells will be assessed. Based on those, we will propose a protocol for detection of tumour-supporting stroma in individual HNSCC patients, which is an important step in personalized medicine of HNSCC. Group of cultures well-supporting and non-supporting chemoresistance will be then analysed for differences in cell stiffness (assessed by atomic force microscopy) and for changes in gene expression (microarray technology) and amino acid profiles (ion-exchange liquid chromatograph). The main aim is to select reliable markers of tumour-supporting stroma detectable in biological samples of HNSCC patients.
