The clinical relevance of biomarkers for aggression assessment and prognosis in non-small cell lung cancer
Pražáková, Markéta ; Topolčan, Ondřej (advisor) ; Ludvíková, Marie (referee) ; Molino, Rafael (referee)
Aim: The aim of this thesis was to measure a large spectrum of biomarkers in serum or plasma of patients with operable stage of NSCLC and to evaluate and compare the clinical utility of these biomarkers in the three most important clinical applications for NSCLC: diagnosis, prognosis and postsurgery follow up care. Patients and methods: Total of 22 biomarkers with the most promising profiles were monitored: 8 standard tumor markers (cytokeratines Cyfra 21-1, TPA, TPS, and MonoTotal, CEA, SCC, TK, Chromogranin A) and 14 potential useful biomarkers including pro-inflammatory cytokines IL-6, IL-8, MCP-1, pro-angiogenic cytokine VEGF, matrix metaloproteinases MMP-1, MMP-2, MMP-7, MMP-9 and their inhibitors TIMP-1 and TIMP-2, adhesion molecules ICAM-1, VCAM-1, growth factor IGF-1, and PAI-1 stimulating tumor growth and angiogenesis. With a view of evaluating the clinical relevance of these markers for NSCLC we measured serum or plasma levels of these 22 markers in group of 93 patients with NSCLC undergoing radical surgery and in group of 20 patients with benign lung disease. For biomarker measurement were used conventional immunoanalytic routine methods (IRMA, REA, CLIA, MEIA, TRACE, ELISA) and multiplex immunoanalytic method. Results: Cyfra 21-1, MonoTotal, TPA, TPS, CEA, SCC, Chromogranin A, TIMP-1, MMP-1,...

Relationship of protein SIVA and signaling pathways Hedgehog/GLI and mTOR to the origin and progression of non-small cell lung cancer.
Vachtenheim, Jiří ; Lischke, Robert (advisor) ; Zemanová, Milada (referee) ; Vodička, Josef (referee)
Non-small cell lung cancer belongs to most frequent malignant tumours at all worldwide. Despite significant progress in knowledge about etiopathogenesis and targeted anticancer therapy, basic scientific research in this particular field and development of more effective treatment remains challenging. In case of its inadequate activation, the Hedgehog signaling pathway is involved in non-small cell cancer development. P53 is well known tumour suppressor gene, that serves as anticancer barrier. Its activity is mostly determined by the transcriptional activation of many pro-apoptotic genes, one of which is SIVA-1. Recently, it has been surprisingly shown, that SIVA-1 has also pro-oncogenic properties in a mouse model of non-small cell lung cancer. The aim of this study was to clarify the importance of Hedgehog signaling pathway and protein SIVA-1 and their potential relationship in development and progression of human non-small cell lung cancer. In selected cell lines of human non-small cell lung cancer, expression of each single component of Hedgehog signalign pathway was detected. In the tissue samples of tumour obtained from 39 patients that underwent surgery for non-small cell lung cancer and selected cell lines of the same tumour, expression of SIVA-1 protein was revealed. These findings indicate...
