    Opis:
    Objectives Reduced efficiency of DNA repair systems has long been a suspected factor in increasing the risk of cancer. In this work authors investigate influence of selected polymorphisms of DNA repair genes (XRCC1, OGG1 and MUTYH) and level of oxidative damage (measured as level of 8-oxo-guanine, 8-oG) on modulation of the risk of colorectal cancer. Material and Methods In group of 324 patients with colorectal cancer the occurrence of polymorphic variants in Ser326Cys of OGG1, Arg399Gln of XRCC1 and Gln324His of MUTYH were studied with TaqMan technique. In addition level of 8-oG in isolated DNA was determined. Results Studied polymorphisms of OGG1, XRCC1 and MUTYH genes influence the risk of CRC: OGG1 Ser326Cys (OR = 1.259, 95% CI: 1.058–1.499, p = 0.007), XRCC1 Arg399Gln (OR = 2.481, 95% CI: 1.745–3.529, p < 0.0001) and MUTYH Gln324His (OR = 1.421, 95% CI: 1.017–1.984, p = 0.039) increase the risk. At the same time, studies examined level of 8-oG for each of the genotypes in both the patient and control group, and have shown that OGG1 Ser326Cys and XRCC1 Arg399Gln are associated with elevated 8-oG level, while MUTYH Gln324His is not, suggesting, that in case of OGG1 Ser326Cys and XRCC1 Arg399Gln CRC risk modulation is connected to mechanisms associated with 8-oG levels. Conclusions This work shows that patients with CRC not only have an increased level of 8-oG and that the studied polymorphisms modulate risk of cancer, but also indicate a relationship between these 2 phenomena, which may contribute to a better understanding of the mechanism of neoplastic process in case of reduced effectiveness of DNA repair mechanisms.

    Opis:
    Objectives Head and neck cancer (HNC) is one of the most common cancers. Most exogenous HNC is head and neck squamous cell carcinomas. Scientists are striving to develop diagnostic tests that will allow the prognosis of HNC. The aim of the study was to determine the risk of HNC. The research concerned changes caused by polymorphisms in genes encoding proteins responsible for the metabolism of xenobiotics. Material and Methods In group of 280 patients with HNC, the occurrence of polymorphic variants in NAT1(rs72554606), NAT2(rs1799930), CYP1A(rs1799814), CYP2D(rs3892097) were studied with TaqMan technique. The control group consisted of 260 cancer free people. The TNM scale was analyzed. Gene interactions of genotyped polymorphisms were investigated. The effects of smoking and alcohol consumption on HNC were assessed. Results The results indicated an increased risk of HNC in NAT1 polymorphisms in the GC genotype (OR = 1.772, 95% CI: 1.184–2.651, p = 0.005) and NAT2 polymorphism in the GA genotype (OR = 1.506, 95% CI: 1.023–2.216, p = 0.037). The protective phenomenon in the CYP1A polymorphism the GT genotype (OR = 0.587, 95% CI: 0.381–0.903, p = 0.015) and the TT genotype (OR = 0.268, 95% CI: 0.159–0.452, p = 0.001). The coexistence of GA-GC polymorphisms (OR = 2.687, 95% CI: 1.387–5.205, p = 0.003) in NAT2-NAT1 genes increases the risk of HNC. Risk-reducing effect in the polymorphism GG-GT (OR = 0.340, 95% CI: 0.149–0.800, p = 0.011), GG-TT (OR = 0.077, 95% CI: 0.028–0.215, p < 0.0001), GA-TT (OR = 0.250, 95% CI: 0.100–0.622, p = 0.002), AA-GT (OR = 0.276, 95% CI: 0.112–0.676, p = 0.002) in NAT2-CYP1A genes. In the CYP2D-CYP1A genes in the polymorphisms CT-CC (OR = 0.338, 95% CI: 0.132–0.870, p = 0.020), TT-GG (OR = 0.100, 95% CI: 0.027–0.359, p = 0.001), TT-GC (OR = 0.190, 95% CI: 0.072–0.502, p = 0.0004), TT-CC (OR = 0.305, 95% CI: 0.107–0.868, p = 0.024). Correlation was noted between cigarette smoking and HNC (OR = 7.297, 95% CI: 4.989–10.674, p < 0.0001) and consuming alcohol (OR = 1.572, 95% CI: 1.003–2.464, p = 0.047). Conclusions The CYP1A polymorphism shows a protective association with HNC. On the other hand, NAT2, NAT1 polymorphism influence the susceptibility to developing HNC. The coexistence of the NAT2-NAT1 genotypes increases the risk of HNC. In contrast, NAT1-CYP1A and CYP1A-CYP2D reduce this risk. Smoking and alcohol consumption increase the incidence of HNC.
