Genetical analysis of head and neck squamous cell carcinomas
Čapková, Markéta ; Plzák, Jan (advisor) ; Smilek, Pavel (referee) ; Čelakovský, Petr (referee)
Head and neck squamous cell carcinoma is the fifth most common cancer worldwide. They are associated with high morbidity and mortality. Despite considerable advances in surgical and oncological treatment over the past two decades, overall treatment outcome has only slightly improved. In my thesis I focused on serum gene expression analysis of head and neck cancer patients, which followed the tissue gene expression analysis in same patients. Further we investigated gene expression analysis in tumour stroma, which is now considered as significant factor in cancer initiation and progression. We revealed several candidate genes, which are involved in signalling pathways connected with cell differentiation and proliferation and are involved in apoptotic pathway (BCl-2, BCl-XL a MAX). As well we detected down-regulation of the main tumour suppressor p 53 protein. In peritumoural tissue we detected overexpression of cytokines typical for embryonal development and ectoderm differentiation - IGF-2 and BMP-4, which significantly influence the phenotype of normal keratinocytes. Further we identified several candidate genes relating with overexpression of Gal-1 in stromal myofibroblasts rich tissue (SPIN1, FUSIP1, TRIM23, SLC25A40, PTPLAD1, MP3K2). HNSCC is a heterogeneous disease despite the presence of...
