Abstract
We present the results of an association study involving hospitalized coronavirus disease 2019 (COVID-19) patients with a clinical background during the 3rd pandemic wave of COVID-19 in Slovakia. Seventeen single nucleotide variants (SNVs) in the eleven most relevant genes, according to the COVID-19 Host Genetics Initiative, were investigated. Our study confirms the validity of the influence of LZTFL1 and 2'-5'-oligoadenylate synthetase (OAS)1/OAS3 genetic variants on the severity of COVID-19. For two LZTFL1 SNVs in complete linkage disequilibrium, rs17713054 and rs73064425, the odds ratios of baseline allelic associations and logistic regressions (LR) adjusted for age and sex ranged in the four tested designs from 2.04 to 2.41 and from 2.05 to 3.98, respectively. The OAS1/OAS3 haplotype 'gttg' carrying a functional allele G of splice-acceptor variant rs10774671 manifested its protective function in the Delta pandemic wave. Significant baseline allelic associations of two DPP9 variants in all tested designs and two IFNAR2 variants in the Omicron pandemic wave were not confirmed by adjusted LR. Nevertheless, adjusted LR showed significant associations of NOTCH4 rs3131294 and TYK2 rs2304256 variants with severity of COVID-19. Hospitalized patients' reported comorbidities were not correlated with genetic variants, except for obesity, smoking (IFNAR2), and hypertension (NOTCH4). The results of our study suggest that host genetic variations have an impact on the severity and duration of acute respiratory syndrome coronavirus 2 (SARS-CoV-2) infection. Considering the differences in allelic associations between pandemic waves, they support the hypothesis that every new SARS-CoV-2 variant may modify the host immune response by reconfiguring involved pathways.

Abstract
INTRODUCTION Lung cancer is the leading cause of cancer-related deaths worldwide. For this reason, huge efforts are being invested in discovering suitable blood biomarkers that would allow early diagnosis and treatment. One of the possible promising candidates for this role are microRNA molecules (miRNAs). The aim of the study was to identify individual blood miRNAs that could be used as potential biomarkers for early diagnosis of lung cancer. METHODS This prospective study analyzed blood samples of 60 patients with early-stage lung cancer, and blood samples of 60 healthy individuals. All study patients with lung cancer had undergone radical pulmonary resection at the University Hospital Ostrava within the study period (2015-2017). Definitive diagnosis of lung cancer was confirmed by histopathology examination of the resected pulmonary specimen. We investigated relative expressions in selected 13 blood miRNAs; the examined miRNAs were miR-126, miR-155, miR-221, miR-21, miR-143, miR-145, miR-133a, let-7a, miR-146a, miR-31, miR-182, let-7g and miR-19b. RESULTS The outcome of this study showed that the levels of the majority of the tested circulating miRNA in lung cancer patients are significantly altered. The most significant serum miRNA biomarkers for the early detection of lung cancer are as follows: miR-143, let-7g, miR-126, let-7a, and miR-145 (miR-143 and miR-145 have oncogene functions, while miR-126, let-7g and let-7a have suppressor functions). CONCLUSIONS We have demonstrated the excellent diagnostic value of several miRNAs (miR-126, miR-143, miR-145, let-7a and let7g). These have an estimated sensitivity and specificity of 75-85% and 0.90-0.93 AUC. However, these individual miRNA biomarkers require further validation in larger prospective cohorts.

Abstract
Targeting metabolomic pathways is a promising strategy for cancer treatment. Alterations in the metabolomic state have also an epigenetic impact, making the metabolomic studies even more interesting. We explored metabolomic changes in the blood plasma of patients with primary and secondary lung cancer and tried to explore their origin. We also applied a discrimination algorithm to the data. In the study, blood samples from 132 patients with primary lung cancer, 47 with secondary lung cancer, and 77 subjectively healthy subjects without any cancer history were used. The samples were measured by NMR spectroscopy. PCA and PLS-DA analyses did not distinguish between patients with primary and secondary lung tumors. Accordingly, no significantly changed levels of plasmatic metabolites were found between these groups. When comparing with healthy controls, significantly increased glucose, citrate, acetate, 3-hydroxybutyrate, and creatinine balanced with decreased pyruvate, lactate, alanine, tyrosine, and tryptophan were found as a common feature of both groups. Metabolomic analysis of blood plasma showed considerable proximity of patients with primary and secondary lung cancer. The changes observed can be partially explained as cancer-derived and also as changes showing ischemic nature. Random Forrest discrimination based on the relative concentration of metabolites in blood plasma performed very promising with AUC of 0.95 against controls; however noticeable parts of differencing metabolites are overlapping with those observed after ischemic injury in other studies.

Abstract
OBJECTIVES Abdominal aortic aneurysm (AAA) and its complications are among the most serious cardiovascular diseases and its occurrence has risen sharply in recent years. The aim of this pilot study is to explore the relationship between the methylation of matrix metalloproteinases and tissue inhibitors of the metalloproteinases genes' promoter region, and abdominal aortic aneurysm (AAA) through the detection of the methylation status of MMP2, TIMP2, TIMP1, and MMP9 genes in peripheral blood. METHODS The study included 43 males with verified AAA (case group) and 34 healthy males (control group). The methylation status of the genes' promoter region was detected by methylation-specific polymerase chain reaction (MS-PCR). RESULTS In adominal aortic aneurysm patients, the methylation ratio of MMP2 gene was positive in 9.3 % (4 cases), 2.3 % (1 case) had methylated TIMP2 gene, 7.0 % (3 cases) had methylated TIMP1 gene, while the methylation ratio of MMP9 gene was positive in 93.0 % (40 cases). In the control group, MMP2 gene was found to be methylated in 5.9 % (2 cases), 5.9 % of cases had methylated TIMP2 and TIMP1 genes (2 cases), and MMP9 gene was found to be methylated in 91.2 % (31 cases). CONCLUSION In our pilot study, we found no association between DNA methylation of gelatinases and their tissue inhibitors, and the development of an abdominal aortic aneurysm (Tab. 2, Fig. 1, Ref. 27).

Abstract
Abdominal aortic aneurysm (AAA) involves complex dynamic remodeling processes in the aortic wall. Gelatinases (MMP2 and MMP9) and their respective tissue inhibitors (TIMP1 and TIMP2) play a crucial role during extracellular matrix (ECM) turnover in aortic tissue. In this study we characterized associations between the haplotypes of genes encoding gelatinase/inhibitor pairs and pathways involved in AAA, a total of 100 AAA patients and 192 controls were enrolled. For males, a significant decrease in the distribution of the minor G allele of the TIMP2 rs8082025 was observed in AAA patients (p = 0.01, 23.1% controls vs. 13.1% AAA). In addition, in males, the major TIMP2 GA haplotype was associated with AAA (86.9% AAA vs. 76.9% control; p = 0.009, OR = 1.997), whereas the TIMP2 GG haplotype (7.7% AAA vs. 13.9% control) was associated with protection against AAA (p = 0.046, OR = 0.518). The minor GAGC MMP9 haplotype was related to AAA for all study subjects as well as the males only subset (p = 0.011, OR = 2.202 and p = 0.025, OR = 2.156, respectively). Small differences in the distribution of gene haplotypes could be associated with different levels of gene expression and in turn influence gelatinases activity in AAA.

Abstract
Phase I enzymes, including cytochrome P450, family 1, subfamily A, and polypeptide 2 (CYP1A2), are involved in the activation of carcinogens to reactive intermediates that are capable of binding covalently to DNA to form DNA adducts, potentially initiating the carcinogenic process. The aim of present study was to investigate the association of CYP1A2 gene polymorphisms and haplotypes with lung cancer risk. A case-control study was carried out on 105 lung cancer patients and 189 controls. To investigate three CYP1A2 polymorphisms: rs2472299, rs2470890, rs11072508 we used a high resolution melting analysis. We found significant allele associations (rs2470890 and rs2422299) with lung cancer risk. We searched for meaningful associations for all variants in the dominant, recessive, and additive genetic models. Genotype associations in the recessive model were of marginal significance for the same single nucleotide polymorphisms. A haplotype analysis included five variants with the frequency higher than 1 %. The haplotype "acc", present with the highest frequency, was associated with increased lung cancer risk (38.7 % vs. 31.5 %; OR 1.38; 95 %CI 0.95-2.01). On the contrary, rare haplotype "gtc" was significantly associated with decreased lung cancer risk in the Slovak population. In conclusion, the present study identified the risk alleles and haploid genotype associations of the CYP1A2 gene in lung cancer.

Abstract
Chromium is a well known carcinogen involved in the lung cancer development. Polymorphism of some of the DNA repair genes may be associated with elevated risk of cancerous transformation. In the present study, we investigated the polymorphisms of the following selected members of the base and nucleotide excision repair genes: XPC (Lys939Gln), XPD (Lys751Gln), XRCC1(Arg399Gln), and hOGG1(Ser326Ser), and the risk they present toward the development of lung cancer, with emphasis on the effect of chromium exposure. We analyzed 119 individuals; 50 patients exposed to chromium with diagnosed lung cancer and 69 healthy controls. Genotypes were determined by a PCR-RFLP method. We found a significantly increased risk of lung cancer development in XPD genotype Lys/Gln (OR=1.94; 95% CI=1.10-3.43; p=0.015) and in the gene combinations: XPD Lys/Gln+XPC Lys/Gln (OR=6.5; 95% CI=1.53-27.49; p=0.009) and XPD Lys/Gln+XPC Gln/Gln(OR=5.2; 95% CI=1.07-25.32; p=0.04). In conclusion, gene polymorphisms in the DNA repair genes may underscore the risk of lung cancer development in the chromium-exposed individuals.

Abstract
Polymorphisms in nucleotide and base excision repair genes are associated with the variability in the risk of developing lung cancer. In the present study, we investigated the polymorphisms of following selected DNA repair genes: XPC (Lys939Gln), XPD (Lys751Gln), hOGG1 (Ser326Cys) and XRCC1 (Arg399Gln), and the risks they present towards the development of lung cancer with the emphasis to gender differences within the Slovak population. We analyzed 761 individuals comprising 382 patients with diagnosed lung cancer and 379 healthy controls. Genotypes were determined by polymerase chain reaction/restriction fragment length polymorphism method. We found out statistically significant increased risk for lung cancer development between genders. Female carrying XPC Gln/Gln, XPC Lys/Gln+Gln/Gln and XRCC1 Arg/Gln, XRCC1 Arg/Gln+Gln/Gln genotypes had significantly increased risk of lung cancer corresponding to OR = 2.06; p = 0.04, OR = 1.66; p = 0.04 and OR = 1.62; p = 0.04, OR = 1.69; p = 0.02 respectively. In total, significantly increased risk of developing lung cancer was found in the following combinations of genotypes: XPD Lys/Gln+XPC Lys/Lys (OR = 1.62; p = 0.04), XRCC1 Gln/Gln+hOGG1 Ser/Ser (OR = 2.14; p = 0.02). After stratification for genders, the following combinations of genotype were found to be significant in male: XPD Lys/Gln+XPC Lys/Lys (OR = 1.87; p = 0.03), XRCC1 Arg/Gln+XPC Lys/Lys (OR = 4.52; p = 0.0007), XRCC1 Arg/Gln+XPC Lys/Gln (OR = 5.44; p < 0.0001). In female, different combinations of the following genotypes were found to be significant: XRCC1 Arg/Gln+hOGG1 Ser/Ser (OR = 1.98; p = 0.04), XRCC1 Gln/Gln+hOGG1 Ser/Ser (OR = 3.75; p = 0.02), XRCC1 Arg/Gln+XPC Lys/Gln (OR = 2.40; p = 0.04), XRCC1 Arg/Gln+XPC Gln/Gln (OR = 3.03; p = 0.04). We found out decreased cancer risk in genotype combinations between female patients and healthy controls: XPD Lys/Lys+XPC Lys/Gln (OR = 0.45; p = 0.02), XPD Lys/Gln+XPC Lys/Lys (OR = 0.32; p = 0.005), XPD Lys/Gln+XPC Lys/Gln (OR = 0.48; p = 0.02). Our results did not show any difference between pooled smokers and non-smokers in observed gene polymorphisms in the association to the lung cancer risk. However, gender stratification indicated the possible effect of heterozygous constitution of hOGG1 gene (Ser/Cys) on lung cancer risk in female non-smokers (OR = 0.20; p = 0.01) and heterozygous constitution of XPC gene (Lys/Gln) in male smokers (OR = 2.70; p = 0.01).

Polymorphisms in tobacco carcinogen metabolizing enzymes may generate interindividual variations towards the risk of developing prostate cancer. One of these enzymes is microsomal epoxide hydrolase (EPHX1) which metabolizes polycyclic aromatic hydrocarbons, or PAH, carcinogens found in cigarette smoke. The activity of this enzyme is affected by two polymorphisms, a substitution of Tyr113 by His in exon 3 and a substitution of His139 by Arg in exon 4. The aim of this study was to use a population-based case-control study to investigate whether or not such genetic polymorphisms in EPHX1 gene can modify the relationship between smoking status and the risk of developing prostate cancer. We used restriction fragment length polymorphism, or PCR-RFLP to determine EPHX1 genotypes in subjects comprising 194 patients with histologically verified prostate cancer and 305 healthy individuals as control. We found no overall association between prostate cancer risk and functional polymorphisms of EPHX1 gene in exon 3 and exon 4. We further analysed the association between the EPHX1 genotypes and smoking. Smokers carrying the exon 3 Tyr/Tyr and Tyr/His genotypes were at no significant risk compared to non-smokers with the "rapid" Tyr/Tyr genotype. By contrast, a significant interaction of smoking and the exon 4 polymorphism was present.

Abstract
OBJECTIVE Workers chronically exposed to hexavalent chromium have elevated risk of lung cancer. Our study investigates the incidence of lung cancer types, age at onset of the disease, and survival time among chromium exposed workers with respect to the expression of anti-apoptotic p53 and pro-apoptotic survivin proteins. MATERIAL AND METHODS 67 chromium exposed workers and 104 male controls diagnosed with lung cancer were analyzed. The mean exposure time among workers was 16.7 ±10.0(SD) years (range 1- 41 years). To investigate the possible regulation of survivin by p53 we examined the expression of both proteins using immohistochemical visualization. RESULTS Chromium exposure significantly decreases the age of onset of the disease by 3.5 years (62.2 ±9.1 in the exposed group vs. 65.7 ±10.5 years in controls; P=0.018). Small cell lung carcinoma (SCLC) amounted for 25.4% of all cases in chromium exposed workers and for 16.3% in non-exposed individuals. The mean survival time in the exposed group was 9.0 ±12.7 vs. 12.1 ±21.9 months in controls, but this difference was not significant. Survivin was predominantly expressed in both cell nucleus and cytoplasm, whereas p53 was expressed in the nucleus. There was a negative correlation between survivin and p53 expression. A decreased intensity of expression and fewer cells positive for survivin was detected in SCLC compared with other types of lung cancer. p53 was expressed in 94.1% and survivin in 79.6% of the samples analyzed. CONCLUSION The study calls attention to decreased expression of survivin, as opposed to p53, in small cell lung carcinoma.

Abstract
Objective The aim of present study was to present the results of a case-control study focused on genetic polymorphisms of selected Phase II metabolizing enzymes (GSTM1, T1, and P1) and to investigate the association of these polymorphisms with lung cancer risk in the Slovakian population. Material and methods The study encompassed 160 lung cancer cases and 220 controls. DNA was extracted from peripheral blood leukocytes, and the polymorphisms of GSTM1, GSTT1 and GSTP1 enzymes were determined by PCR-based methods. We determined the genotype distribution of all these genes and their combinations. The association between specific genotypes and the development of lung cancer were examined using logistic regression analysis to calculate odds ratios (OR) and 95% confidence intervals (CI). Results We found that the GSTM1 null genotype (OR = 1.6; 95% CI = 1.03-2.4; χ2 = 4.08, and P = 0.04) was associated with elevated risk. A significant correlation also was found for the combined genotypes of GSTM1 null and GSTP1 Ile/Val and Val/Val (OR = 2.01; 95% CI = 1.1-6.1; χ2 = 3.6, and P = 0.02) and GSTM1 null and GSTT1 positive (OR = 2.00; 95% CI = 1.2-3.2; χ2 = 7.3, and P = 0.006). Conclusions We conclude that the genotype of metabolizing enzymes and allelic combinations underscore the risk for lung cancer. Individual risk assessment may be further improved by increasing the number of polymorphisms studied and combining them with the traditional epidemiological risk factor.

Abstract
OBJECTIVE Workers chronically exposed to hexavalent chromium have higher incidence of lung cancer. Our study investigates incidence of lung cancer types, age at onset of the disease and survival time among chromium exposed workers (smelters, tapers, crane operators) in comparison to non-exposed persons. METHODS 64 chromium exposed workers and 104 male controls with diagnosed lung cancer were analysed. The average exposure time among workers was 16.71 +/- 10.02 (S.D.) years (range 1- 41 years). RESULTS Chromium exposure significantly decreases the age at the onset of the disease by 3.51 years (62.20 +/- 9.08 years in exposed group and 65.71 +/- 10.50 years in control; P=0.018). Small cell lung carcinoma (SCLC) forms 25.0 % of all cases in chromium exposed workers and 16.34% in non exposed individuals. No correlation was found between the age at the diseases onset and time of exposure. The mean survival time in exposed group was 9.03 +/- 12.73 month, in control 12.14 +/- 21.94 month, but this difference was not significant (P=0.473). CONCLUSION Occupational exposure to chromium was identified as an important risk factor of lung cancer, decreasing the age at the diseases onset. Higher percentage of SCLC was found in chromium exposed individuals.

Abstract
OBJECTIVES Welders, chronically exposed to hexavalent chromium, may exhibit disturbances in chromosomal integrity. Our study investigates chromosomal damage related to chromium exposure, considering the role of polymorphisms in relevant DNA repair genes. METHODS 39 male welders exposed to chromium for 10.2+/-1.67 years and 31 male controls were assayed for structural chromosomal aberrations (conventional cytogenetic analysis). DNA repair gene polymorphisms were determined by Real-Time allelic discrimination assay. RESULTS Total chromosomal aberrations were moderately, but statistically not significant, higher in exposed individuals (1.96%) than in controls (1.55%). Chromosomal type breaks were almost two-fold higher in exposed than in control individuals. The highest frequency of total chromosomal aberrations was recorded in individuals with homozygous variant Gln/Gln cariers (2.14%) in XRCC1* Arg-399Gln and the lowest in those with the wild-type Arg/Arg cariers (1.33%). Polymorphisms in XRCC3 gene did not modulate the frequencies of CAs, CTAs and CSAs. CONCLUSIONS Understanding the effects of chromium on chromosomal integrity in relation to individual susceptibility may be a basis for preventive measures in working process.
