The question of the relationship between the accumulation of DNA damage, disorders in DNA repair pathways, and increased risk of disease development is still relevant. Over the past few years, significant efforts have been made to develop methods for analyzing the activity of DNA repair enzymes in human cells. In this work, we developed fluorescent DNA probes that allow us to determine the activity of key enzymes of base excision DNA repair in cell extracts, namely the DNA glycosylases UNG2, SMUG1, MBD4, TDG, AAG, NEIL1, NTHL1, and OGG1 and the AP endonuclease APE1. The sensitivity of DNA probes was determined on pure enzyme preparations. Determination of the activity of repair enzymes in cell extracts of the human ovarian tumor lines TOV112, 79, OVCAR3, MESOV, SCOV3, and TOV21 revealed significant variability in the level of enzyme activity in these cell lines. These results may become a test system platform for analyzing the activity of the base excision DNA repair system in the human body.",
