Назва : DNA damage in tumor cells and peripheral blood lymphocytes of endometrial cancer patients assessed by the comet assay

Анотація: To date, genome instability is considered to be a common feature not only of tumor cells, but also of non-malignant cells of cancer patients, including peripheral blood lymphocytes (PBLs). The issue of the association between genome instability in tumor cells and PBLs, as well as of its relationship with tumor progression remains poorly understood. Aim: To evaluate the level DNA damage in tumor cells and PBLs of endometrial cancer (EC) patients with regard to clinical and morphological characteristics of the patients. Materials and Methods: DNA damage was assessed in 106 PBLs samples and 42 samples of tumor cell suspension from EC patients by comet assay. PBLs from 30 healthy women were used as control. The level of DNA damage was expressed as the percentage of DNA in the comet tails (% tail DNA). Results: It was revealed that the amount of DNA damage in PBLs of EC patients was 2.2 times higher in comparison with that of healthy donors (8.3 ± 0.7 and 3.7 ± 0.4% tail DNA, respectively) (p 0.05). In this study, no association between the levels of DNA damage in endometrial tumor cells and PBLs was observed (r 0.05). The amounts of DNA damage both in tumor cells and PBLs were not related to the degree of tumor differentiation as well as the depth of myometrial invasion, but depended on the body mass index (BMI) of EC patients: high level of lesions was observed in patients with elevated BMI values. Furthermore, the level of DNA damage in tumor cells was associated to familial aggregation of cancer and was significantly higher in endometrial cells from patients with family history of cancer vs that from EC patients with sporadic tumors (32.3 ± 2.9 and 22.8 ± 1.8% tail DNA, respectively) (p 0.05). It was also found that for women who had high level of DNA damage in PBLs, the risk of EC was greater (odds ratio value of 3.5) compared to those with low level of such lesions. Conclusion: Genome instability that appears as an increased level of DNA damage in tumor cells and PBLs of EC patients is associated with BMI and family history of cancer and can reflect a predisposition to cancer

Genomic instability and sensitivity to genotoxic estrogen metabolites in cells of EC patients depend on the DNA repair efficiency. The aim of the study was to analyze the level of DNA damage in peripheral blood lymphocytes (PBL) of EC patients after treatment with the 4OHE2 and to evaluate the repair efficiency of induced DNA damag

Анотація: The development of hormone-dependent cancers, including endometrial carcinomas, in great part may be mediated by the genotoxic effects of estrogen metabolites, among which 4-hydroxyestradiol (4OHE2) is characterized by the most prominent DNA-damaging properties. It is assumed that the individual sensitivity to the 4OHE2 may determine the predisposition to endometrial cancer (EС). Aim: To analyze the sensitivity of peripheral blood lymphocytes (PBLs) of EC patients to the 4OHE2 and to evaluate the repair efficiency of 4OHE2-induced DNA damage. Materials and Methods: The study was performed on the PBLs of 53 EC patients and 20 healthy women. The level of DNA damage was measured using the comet assay and was expressed as % tail DNA. The DNA repair efficiency (%) was evaluated by determining the ratio between the amount of repaired DNA damage and the level of 4OHE2-induced damage that appeared after incubation of PBLs with 4OHE2. Results: In PBLs of EC patients, a higher level of 4OHE2-induced DNA damage (32.0 ± 2.2% tail DNA) and lower DNA repair efficiency (34.0 ± 4.5%) was observed compared to PBLs of healthy women (22.3 ± 2.3% tail DNA and 48.8 ± 4.5%, respectively). PBLs of EC patients with deep tumor invasion of myometrium were characterized by more prominent decrease of DNA repair than those with less invasive tumor ( ½ of myometrium) (20.9 ± 7.8 and 43.7 ± 6.7%, respectively). Furthermore, lower DNA repair efficiency was detected in the PBLs of EC patients with a family history of cancer compared to this parameter in patients with sporadic tumors (20.9±7.8 and 47.1 ± 5.5%, respectively). Conclusion: The PBLs of EC patients are characterized by increased sensitivity to the genotoxic effect of 4OHE2 and reduced repair efficiency regarding 4OHE2-induced DNA damage. A lower level of DNA repair is observed in EC patients with deep tumor myometrial invasion and a family history of cancer

Анотація: Despite a significant number of epidemiological studies on potential carcinogenicity of microwave radiation (MWR) from wireless devices and a bulk of experimental studies on oxidative and mutagenic effects of low intensity MWR, the discussion on potential carcinogenicity of low intensity MWR is going on. This study aims to assess oxidative and mutagenic effects of low intensity MWR from a typical commercial model of a modern smartphone. Materials and Methods: The model of developing quail embryos has been used for the assessment of oxidative and mutagenic effects of Global System for Mobile communication (GSM) 1800 MHz MWR from a commercial model of smartphone. The embryos were exposed in ovo to 0.32 µW/cm2, discontinuously — 48 s — On, 12 s — Off, during 5 days before and 14 days through the incubation period. Results: The exposure of quail embryos before and during the incubation period to low intensity GSM 1800 MHz has resulted in expressive statistically significant oxidative effects in embryonic cells, including a 2-fold increase in superoxide generation rate and 85% increase in nitrogen oxide generation rate, damages of DNA integrity and oxidative damages of DNA (up to twice increased levels of 8-oxo-dG in cells of 1-day old chicks from the exposed embryos). Finally, the exposure resulted in a significant, almost twice, increase of embryo mortality. Conclusion: The exposure of model biological system to low intensity GSM 1800 MHz MWR resulted in significant oxidative and mutagenic effects in exposed cells, and thus should be recognized as a significant risk factor for living cells

Анотація: Recent studies allow to consider the mitochondrial ribosomal protein S18-2 (MRPS18-2, S18-2) as a potential oncoprotein, which suggests the need for further characterization of its expression in tumors of different genesis including breast cancer (BC). The aim of the study was to analyze the expression of the S18-2 protein in BC of luminal A and basal subtypes. Materials and Methods: Operational material of BC patients stage І–ІІ (luminal A subtype, n = 30, and basal subtype, n = 10) was studied with the use of morphological, immunohistochemical, statistical and bioinformatic methods. Results: Using the immunohistochemical analysis, we found that the S18-2 protein showed the nuclear signal in 66.7% of luminal A subtype BC samples and 80.0% of basal subtype BC samples. The variability of the S18-2 expression in both the luminal A and basal subtypes of BC was revealed. Noteworthy, the number of cells expressing S18-2 in high-proliferating tumors of luminal A and basal subtype is significantly higher than in tumors with a low proliferative potential (p 0.05). In 10 samples of luminal A subtype, the nuclear S18-2 signal was higher than median value. Moreover, the S18-2 protein was overexpressed in 4 out of such 10 samples. Metastases in the lymph nodes were found in 3 out of 4 patients with the stage II BC, low differentiation grade of the tumor and high proliferative activity. The bioinformatic analysis confirms our preliminary findings that the trend for increasing expression of the S18-2 protein in tumors correlates with the aggressiveness of malignant BC. Conclusion: The S18-2 protein may be a marker of cancer aggressiveness in BC patients
