Disturbances or even failure of repair processes trigger a chain of reactions leading to genome instability and oncogenic transformation of the cell. \u0000<b>Purpose.</b> To investigate the association of single nucleotide polymorphism in genes of nucleotide excision repair (<i>ERCC2</i> rs13181, <i>XPC</i> rs2228001), AP site repair (<i>APEX</i> rs1130409), homologous recombination (<i>XRCC3</i> rs861539), single-strand DNA break repair (<i>XRCC1</i> rs25487), and double-strand DNA break repair (<i>PARP</i> rs1136410, <i>XRCC4</i> rs2075685) with the risk of development of malignant neoplasms of various localizations in chronically exposed persons. \u0000<b>Materials and methods.</b> The study was perfomred in 861 individuals who were chronically exposed to low-dose low-rate radiation, 274 of which had malignant neoplasms (MN) of various localizations and 587 made up the comparison group (exposed persons without MN). The mean cumulative dose to red bone marrow (RBM) in the group of people with MN was 561.65 ± 25.31 mGy, while in the comparison group it was 543.14 ± 36.06 mGy. Genotyping of polymorphic loci rs13181, rs2228001, rs1130409, rs861539, rs25487, rs1136410, and rs2075685 was performed by real-time PCR. The association of polymorphic loci with the risk of MN development was determined by the odds ratio (OR) and 95% confidence interval (95% CI). A multifactor dimensionality reduction method was used to assess intergenic interactions. \u0000<b>Results.</b> Single-stranded DNA break repair gene (<i>XRCC1</i>) rs25487 polymorphism in accordance with the dominant model is associated with an increased risk of MN development in the combined group of the examined persons (OR = 1.79 (1.12‒2.87), <i>p</i> = 0.01) and in the Slavs group (OR = 2.26; 95% CI 1.06-4.81; <i>p</i> = 0.03).

Therefore, there is a need to identify new agents, such as gallic acid (GAL), that can exert a synergistic effect to elucidate the pathophysiological mechanisms of the chemotherapeutic effects of CIS and to increase the effectiveness of treatment by preventing drug resistance. For this purpose, we investigated the stimulatory role of GAL on CIS-induced human laryngeal cancer (Hep-2) cell death via TRPM2 channel activation. For the study, four groups were formed from human laryngeal cancer (Hep-2) cells as Control, GAL (1OO μM), CIS (25 μM), and GAL + CIS.

CIS treatment caused laryngeal cancer cell cytotoxic and increased Cas-3-9, ROS, IL-1β, TNF-α, IL-6, TOS, LPx, TRPM2, and PARP-1 levels while decreasing cell viability, GSH-Px, GSH, and TAS levels. The combination of GAL and CIS treatment made the treatment even more effective.
