Ovarian cancer is serious and one of the most common gynecologic cancers. Carboplatin is the therapeutic agent of the first choice in the ovarian cancer therapy. However, after the primary therapeutic response to carboplatin, the relapse of the disease may occur with developed resistance to carboplatin. Chemoresistance and insufficient therapy response are considered to be the reason of the high mortality rate of ovarian cancer. The DNA damage response pathways play an important role in the therapeutic response and chemoresistance development. Restoration of homologous recombination function in cancers is the key mechanism of resistance development to platinum agents. Based on this knowledge, we formed our hypothesis, that the inhibition of homologous recombination could increase the sensibility to carboplatin. The main goal of this thesis was to define the role of double-strand breaks repair in response to chemotherapy of ovarian cancer. Protein MRE11 is part of the MRN complex, that participates in double-strand breaks repair. Using mirin as a pharmaceutic inhibitor of MRE11 we were aiming to determine the impact of homologous recombination on the effect of carboplatin and its role in resistant development to carboplatin. In the practical part of the thesis, we described the association between...
