3. Molecular biomarkers related to DNA damage and repair: their role in carcinogenesis, patients' treatment and monitoring

Author

Vodenková, Soňa, Vodička, Pavel, Anděra, Ladislav, and Černá, Marie

Abstract

Genome instability represents one of the leading forces driving the onset and development of cancer. It arises as a consequence of the combined effect of DNA damage and errors made by the DNA repair system. In many cancers, DNA damage tolerance and DNA repair pathways are disrupted or deregulated, thereby promoting cancer progression. DNA repair also appears to play a substantial role in cancer therapy response. This Dissertation Thesis was performed in response to several unclear and unresolved issues of the role of DNA damage and DNA repair in cancer pathogenesis. The aim of the Thesis was to search for potential novel biomarkers and confirmation of the validity of already existing biomarkers related to DNA damage and DNA repair, which may be associated with cancer susceptibility and patient's clinical outcome. We also explored the biological basis of different biomarkers and their associations. The major outcomes of this Thesis are: 1) The elevated chromosomal aberrations (CAs) in peripheral blood lymphocytes (PBLs) may serve as a biomarker of cancer susceptibility and partially affects patients' clinical outcome. While telomere shortening contributes to the formation of CAs in PBLs only in healthy individuals, less efficient DNA double- strand break repair in PBLs is associated with telomere...

Abstract

The majority of human cancers arise due to cells inabitily to maintain genomic stability. Cytogenetic changes (especially chromosomal aberrations) in peripheral blood lymphocytes which reflect not only the individual exposure to genotoxic factors, but also individual sensitivity to genotoxic effect and the tumor is late consequence to genotoxic effect. Summary epidemiological prospective studies over the last ten years have shown that increased level of chromosomal aberrations in peripheral blood lymphocytes is predictive of cancer risk. This thesis is focused on the detection of particular types of chromosomal damage in patients with choosed types of newly diagnosed cancers compared to healthy control persons. We cytogenetically analyzed 100 patients with colorectal cancer and 298 controls and 123 patients with breast cancer and 123 controls - healthy women. We compared the percentage of aberrant cells, the percentage of total aberrations, the percentages of chromatid and chromosome aberrations found in patients with both types of tumors and in controls and we verified the predictive value of chromosomal aberrations as a biomarker of cancer risk. In patients with colorectal cancer was statistically significantly increased only the level of chromatid aberrations (CHTA) (1,45±1,28) compared to...

Abstract

The comet assay is a versatile method to detect nuclear DNA damage in individual eukaryotic cells, from yeast to human. The types of damage detected encompass DNA strand breaks and alkali-labile sites (e.g., apurinic/apyrimidinic sites), alkylated and oxidized nucleobases, DNA-DNA crosslinks, UV-induced cyclobutane pyrimidine dimers and some chemically induced DNA adducts. Depending on the specimen type, there are important modifications to the comet assay protocol to avoid the formation of additional DNA damage during the processing of samples and to ensure sufficient sensitivity to detect differences in damage levels between sample groups. Various applications of the comet assay have been validated by research groups in academia, industry and regulatory agencies, and its strengths are highlighted by the adoption of the comet assay as an in vivo test for genotoxicity in animal organs by the Organisation for Economic Co-operation and Development. The present document includes a series of consensus protocols that describe the application of the comet assay to a wide variety of cell types, species and types of DNA damage, thereby demonstrating its versatility.The comet assay is commonly used to assess DNA damage. This collection of consensus protocols includes adaptations for a wide range of species and sample types, assay formats and detection of different types of DNA lesions.

7. Significance of mitochondrial DNA in colorectal cancer

Author

Danešová, Natálie, Vodenková, Soňa, and Polívková, Zdeňka

Abstract

Colorectal cancer is the third most commonly diagnosed cancer worldwide and the second leading cause of cancer death. It is a heterogeneous and multifactorial disease, the development of which takes up to 15 years. In addition to genetic risk factors, external, influenceable factors also contribute to the development of the disease. Patients are often diagnosed in the late stages of the disease, which significantly reduces the chances of their successful treatment. It is therefore necessary to identify appropriate screening, diagnostic, prognostic and predictive biomarkers of the disease. Mitochondria are organelles found in almost all eukaryotic cells and their dysfunction is often involved in the development of cancer. Because mitochondria have their own DNA its changes could serve as a potential biomarker for a closer understanding of the pathogenesis and progression of colorectal cancer. The main goal of this bachelor thesis was to summarize previous studies focused on mitochondrial DNA changes in patients with colorectal cancer and their possible use in clinical practise.
