The effects of chemicals on cell lines viability
 Zemanová, Anita ; Obruča, Stanislav (referee) ; Brázda, Václav (advisor)
The subject of this diploma thesis is the influence of selected chemicals on cell lines viability. The theoretical part contains options of cancer treatment by using chemotherapeutics including their mechanism of action and side effects. Additionally, there are described alternative DNA structures with focus on G-quadruplexes and ligands that interact with G-quadruplexes. These compounds are promising drugs in cancer treatment due to their high specificity to G-quadruplexes, which are found in telomeres of chromosomes. G-quadruplex interacting ligands by stabilization of G-quadruplexes can inhibit the enzyme telomerase, which is necessary for telomere lengthening of rapidly dividing cancer cells. Additionally, the possibilities of viability assays are summarized in the theoretical part. The aim of the experimental part was comparing cytotoxic activity between commercially available chemotherapeutics and selected G-quadruplex interacting ligands. Another task was the study of apoptosis and necrosis after the treatment of selected chemicals on cell lines and after the localization of ligands interacting with G-quadruplexes in the cells of the breast cancer cell line. In the experimental part, G-quadruplex interacting ligands have been shown to exhibit similar cytotoxic activity to commercially available chemotherapeutic agents.
