Abstract
Abstract
Heart failure (HF) symptoms are related to reduced circulatory perfusion, peripheral congestion, also impaired peripheral muscle strength & oxygen utilization due to iron deficiency. Despite many premises, the correlation between myocardial iron load and failing heart function was not proved.
The purpose of this study was to assess iron itself and iron-related proteins in human failing (FH) vs non-failing (NFH) myocardium.
The study group consisted of 58 explanted FHs vs the control consisted of 31 NFHs unsuitable for transplantation. HF study group presented with LV dilatation (LVDD 67±8 mm; LVSD 59±13 mm), reduced contraction (LVEF 20±7.5%), RV enlargement (RVD 42±6.5 mm), pulmonary hypertension (2.21±0.93 Wu) and elevated NTproBNP (3955.5±2250.5pg/ml).
We assessed iron serum markers: ferritin (FR), transferrin/saturation (TSAT), transferrin receptor (soluble sTfR), sTFR/log FR; myocardial iron homeostasis assessment: M-Iron (Instrumental Neutron Activation Analysis, μg/g) and iron gathering proteins (by ELISA): divalent metal transporter (DMT-1); L-type calcium channel (L-CH), TfR-1/TfR-2; ferritins: heavy (FT-H), light (FT-L) chain, mitochondrial (FT-MT); ferroportin (FPN) and oxidative stress marker: 4-hydroxynonenal (4-HNE).
In FH vs NFH, M-Iron was reduced (164.6±25.2 vs 182.3±23.9; p=0.0358) however, did not apply to the entire group. Therefore we divvied the FH group into two subgroups (based on M-Iron concentration in NFH controls). Average iron concertation in non-iron-deficient (NIDM) subgroup was 172.5±19.1 (n=35) and in iron-deficient (IDM) subgroup wad 127.0±16.5; (n=23, p=0.0001).
Regardless M-Iron load in FH vs NFH myocardial proteins expressions were reduced: L-CH (NIDM vs IDM vs NFH: 49.2±9.2; 42.5±4.2; 67.3±23.0, p=0.0022); FT-L (16.4±7.3; 11.6±4.8; 26.3±7.5, p= <0.0001, respectively); FT-MT (41.2±7.6; 38.7±4.1; 59.3±10.4 p≤0,0001, respectively). With regard to M-Iron load, only in DMT-1 expression was changed (NIDM vs IDM vs NFH 4.8±0.7; 4.0±0.5; 5.8±0.8; p≤0.0001). 4-HNE levels in FH vs NFH were increased, regardless M-Iron load (NIDM-Iron vs IDM-Iron vs NFH; 55.7±29.2; 57.2±47.8; 9.9±8.1 p≤0.0001).
Interestingly, the iron load (NIDM-Iron vs IDM-Iron) did not modify the assessed clinical parameters.
With regard to commonly used systemic iron markers only sTFR/log FR proved M-Iron load difference (NIDM-Iron vs IDM-Iron 0.6±0.2; 0.7±0.3; p=0.047910)
In FH, we observed, the subgroup with the reduced M-Iron load. The observed reduction of iron gathering proteins were independent on M-Iron load, except DMT-1 the main iron transportation protein into the cell. The results showed that the HF degree and concertation of iron proteins are unlikely to be affected by the M-Iron load, except DMT-1 protein. The oxidative stress was also regardless from M-Iron load, and increased in the whole FH group. Commonly used systemic iron markers except sTFR/log FR did not define M-Iron load.

Abstract
Diesel exhaust emissions (DEE), being one of the main causes of ambient air pollution, exert a detrimental effect on human health and increase morbidity and mortality related to cardiovascular and pulmonary diseases. Therefore, the objective of the present study was to investigate potential adverse effects of exhausts emissions from B7 fuel, the first-generation biofuel containing 7% of fatty acid methyl esters (FAME), and SHB20 fuel, the second-generation biofuel containing 20% FAME/hydrotreated vegetable oil (HVO), after a whole-body exposure with and without diesel particle filter (DPF). The experiment was performed on 95 male Fischer 344 rats, divided into 10 groups (8 experimental, 2 control). Animals were exposed to DEE (diluted with charcoal-filtered room air to 2.1-2.2% (v/v)) for 7 or 28 days (6 h/day, 5 days/week) in an inhalation chamber. DEE originated from Euro 5 engine with or without DPF treatment, run on B7 or SHB20 fuel. Animals in the control groups were exposed to clean air. Our results showed that the majority of haematological and biochemical parameters examined in blood were at a similar level in the exposed and control animals. However, exposure to DEE from the SHB20 fuel caused an increase in the number of red blood cells (RBC) and haemoglobin concentration. Moreover, 7 days exposure to DEE from SHB20 fuel induced genotoxic effects manifested by increased levels of DNA single-strand breaks in peripheral blood lymphocytes. Furthermore, inhalation of both types of DEE induced oxidative stress and caused imbalance of anti-oxidant defence enzymes. In conclusion, exposure to DEE from B7, which was associated with higher exposure to polycyclic aromatic hydrocarbons, resulted in decreased number of T and NK lymphocytes, while DEE from SHB20 induced a higher level of DNA single-strand breaks, oxidative stress and increased red blood cells parameters. Additionally, DPF technology generated increased number of smaller PM and made the DEE more reactive and more harmful, manifested as deregulation of redox balance.

Abstract
Increasing use of silver nanoparticles (AgNPs) results in increased human exposure. AgNPs are able to cross brain-blood barrier and are a risk factor for the brain. Thus, we hypothesized that AgNPs exposure might affect hippocampal dependent memory, which required cognitive coordination processes. To verify the assumption, in this study we evaluated the effects of orally administered bovine serum albumin (BSA)-coated AgNPs on spatial memory, which engage cognitive coordination processes for on-going stimuli segregation. Rats following 28 days of oral administration with 1 mg/kg (n = 10) or 30 mg/kg (n = 10) BSA-AgNPs or saline, a control groups (n = 10, n = 8), were tested with an active place avoidance task in the Carousel Maze test. The study revealed significant impairment of long- and short-term memory, irrespectively of dose of AgNPs, whereas non-cognitive activity was on a similar level. We found significantly higher content of silver in the hippocampus in comparison to the lateral cortex. No silver was found in the cerebellum and the frontal cortex. The nanoSIMS analysis reveal a weak signal of silver in the hippocampus of AgNPs treated animals that should be attributed to the presence of silver in ionic form rather than AgNPs. Our findings indicate that oral exposure to a low dose AgNPs induces detrimental effect on memory and cognitive coordination processes. The presence of silver ions rather than AgNPs in different brain regions, in particular the hippocampus, suggests crucial role of silver ions in AgNPs-induced impairment of the higher brain functions.

Abstract
Background and Purpose—
Atrial fibrillation (AF) is increasingly recognized as the single most important cause of disabling ischemic stroke in the elderly. We undertook an international survey to characterize the frequency of AF-associated stroke, methods of AF detection, and patient features.
Methods—
Consecutive patients hospitalized for ischemic stroke in 2013 to 2014 were surveyed from 19 stroke research centers in 19 different countries. Data were analyzed by global regions and World Bank income levels.
Results—
Of 2144 patients with ischemic stroke, 590 (28%; 95% confidence interval, 25.6–29.5) had AF-associated stroke, with highest frequencies in North America (35%) and Europe (33%) and lowest in Latin America (17%). Most had a history of AF before stroke (15%) or newly detected AF on electrocardiography (10%); only 2% of patients with ischemic stroke had unsuspected AF detected by poststroke cardiac rhythm monitoring. The mean age and 30-day mortality rate of patients with AF-associated stroke (75 years; SD, 11.5 years; 10%; 95% confidence interval, 7.6–12.6, respectively) were substantially higher than those of patients without AF (64 years; SD, 15.58 years; 4%; 95% confidence interval, 3.3–5.4;
P
<0.001 for both comparisons). There was a strong positive correlation between the mean age and the frequency of AF (
r
=0.76;
P
=0.0002).
Conclusions—
This cross-sectional global sample of patients with recent ischemic stroke shows a substantial frequency of AF-associated stroke throughout the world in proportion to the mean age of the stroke population. Most AF is identified by history or electrocardiography; the yield of conventional short-duration cardiac rhythm monitoring is relatively low. Patients with AF-associated stroke were typically elderly (>75 years old) and more often women.

Abstract
Silver nanoparticles (AgNPs) are widely used in industry and medicine but the recent evidence for their cytotoxicity rise a concern about the safety of their use. We have previously shown that human A549 cells are resistant to AgNPs cytotoxicity, as compared with similarly treated HepG2 cells. In order to check for the role of the NF-κB signaling pathway in response of A549 and HepG2 cell lines to the treatment with 20 nm and 200 nm AgNps, we analyzed the expression of 84 key genes related to the functionality of the NF-κB signaling pathway. We observed considerable alternations in gene expression in HepG2 cells treated with 20 nm AgNPs, and minor changes when exposed to 200 nm AgNPs. Surprisingly, no changes in gene expression were observed in A549 cells treated with both size AgNPs. Using the NF-κB luciferase reporter system, we further tested the basal activity and inducibility of the NF-κB pathway in both cell lines and found that the inducibility of NF-κB signaling in A549 cells is approximately 5 times lower than this of HepG2 cells, but the basal activity is approximately 3.5 times higher. In accordance, the NF-κB activation after AgNPs treatment was observed in HepG2 but not in A549. Altogether indicate that NF-kB mediated cellular response to AgNPs is cell type specific and related to the basal activity of NF-κB.

Abstract
The radiolytic degradation of widely used fungicide, carbendazim, in synthetic aqueous solutions and industrial wastewater was investigated employing γ-irradiation. The effect of the absorbed dose, initial concentration and pH of irradiated solution on the effectiveness of carbendazim decomposition were investigated. Decomposition of carbendazim in 100 μM concentration in synthetic aqueous solutions required irradiation with 600 Gy dose. The aqueous solutions of carbendazim have been irradiated in different conditions, where particular active radical species from water radiolysis predominate. The obtained data have been compared with the kinetic modeling. The reversed-phase high-performance liquid chromatography was used for the determination of carbendazim and its radiolytic decomposition products in irradiated solutions. The changes of toxicity of irradiated solutions were examined with different test organisms and human leukemia cells.

Abstract
Radioiodine treatment of hyperthyroid patients with autonomous thyroid nodule leads to cellular DNA damage not only in thyrocytes but also in peripheral blood lymphocytes. The purpose of this study was to evaluate DNA breakage and base damage in thyrocytes and lymphocytes in patients treated with 131-I. In all the patients thyroid scintiscan was performed using 131-I. Damage to DNA was estimated by comet assay. Samples were taken before radioiodine treatment, and 12 and 54 days afterwards. Our results indicate high diversity in the level of DNA damage among the individual patients. However, in all cases, after 54 days the level of DNA damage in lymphocytes was similar or even lower than that in the controls. In contrast, in hot nodule the DNA damage persisted until the 54th day after 131-I application. Differences in the type of DNA damage between thyrocytes and lymphocytes were also observed. In lymphocytes there was more base damage, whereas in thyrocytes single strand breaks prevailed. This may indicate different mechanisms of DNA damage induction and/or DNA repair.

Abstract
A relatively high number of bovine cryopreserved oocytes analyzed by the comet assay (Men et al. 2003 Mol. Reprod. Dev. 64, 245) showed compromised DNA integrity. The DNA fragmentation (comet tails) was found in 29% of slow cooled oocytes, in 20% of oocytes vitrified in straws and in 24% of oocytes vitrified in open pulled straws (OPS). Present study used the comet assay to compare the DNA status of 151 in vitro matured bovine oocytes vitrified in straws, in OPS or in droplets. It was assumed that the droplet method (Papis et al. 2000 Theriogenology 54, 651), which has gentle pre-equilibration prior to vitrification, would offer better protection of DNA. OPS vitrification was performed using a solution consisting of 20% DMSO, 20% ethylene glycol (EG), and 0.5 M sucrose. For in-straw and in-droplet vitrification, VS14 (5.5 M EG and 1.0 M sucrose) solution was used. In these two methods pre-equilibration in 3% EG solution for 15 min was applied. Fresh oocytes exposed to 0.5 mM of hydrogen peroxide for 5 min served as the positive control. Fresh M II oocytes served as the negative control. The comet assay was performed according to the procedure of Men et al. (2003) with some modifications aimed at enhancing the sensitivity of the method. The zona pellucida was removed using 0.5% pronase solution, followed by placing of the oocytes in droplets of low-melting agarose on slides. These were subjected to overnight treatment in lysis buffer, followed by 40 min of DNA unfolding and 30 min electrophoresis. Following air drying, the slides were stained with DAPI fluorochrome and photographed. The pictures were saved as anonymous consecutive files to enable objective assessment. Of 119 vitrified oocytes, 112 (94%) were evaluated. The remainder were lost or displayed atypical pictures. The comets could not be analyzed with the Comet v.3.0 software, possibly due to the large size of each oocyte. Six main classes of comet tails were distinguished ranging from no tail (class 0) to heavy and long tail (class 5). Positive control oocytes displayed class 4 (36%) or 5 (64%) tails. Negative control oocytes formed class 0 (18%) to class 3 (47%) comet tails. The oocytes vitrified using minimum volume methods fell within the same range, with 80% and 76% of oocytes vitrified in droplets and OPS, respectively, forming class 1 or 2 tails. One OPS vitrified oocyte (2.2%) expressed a class 5 tail. A small but significant proportion of oocytes vitrified in straws (15.4%, P d 0.05, ANOVA) formed class 4 tails typical of positive control oocytes. In conclusion, in spite of pre-equilibration, a significant proportion of oocytes vitrified in straws contained detectable levels of DNA fragmentation, due probably to the lower cooling rate. The minimum volume protocols (the droplet and OPS methods) caused virtually no damage as assessed by the DNA comet assay. Results presented here differ from those reported previously. Reasons for differences remain to be established.

Abstract
PURPOSE To investigate the role of poly(ADP-ribosylation) in DNA double-strand break repair and fixation in murine lymphoma L5178Y (LY) sublines, LY-R and LY-S, and a pair of Chinese hamster ovary lines: wild-type and mutant xrs6 cells, that have differences in repair competence and degree of radiosensitization with poly(ADP-ribosylation) inhibitors. MATERIALS AND METHODS Cells (asynchronous, logarithmic phase) were pre-incubated with 2 mM aminobenzamide at 37 or 25 degrees C, X-irradiated with 10 Gy and allowed to repair DNA breaks for 15, 60 and 120 min at 37 or 25 degrees C. The remaining double-strand break were estimated by the neutral comet assay. RESULTS At 37 degrees C, no effect of AB treatment on the repair kinetics was observed either in xrs6 or Chinese hamster ovary (wild-type) cells. In contrast, aminobenzamide decreased the repair of double-strand break in the LY-S line but not the LY-R line, in agreement with the previously observed radiosensitization of LY cells by poly(ADP-ribosylation) inhibition. However, double-strand break rejoining in the repair competent cell lines, Chinese hamster ovary and LY-R, also was affected by aminobenzamide when the post-irradiation incubation was carried out at 25 degrees C. Analysis of these results together with earlier data on LY-S cells have been interpreted in terms of Radford's model of radiation damage fixation. CONCLUSION The reported results indicate that poly(ADP-ribosylation) can be an important modulator of the conversion of DNA damage to lethal events.

Abstract
We examined the response to hydrogen peroxide of two L5178Y (LY) sublines which are inversely cross-sensitive to hydrogen peroxide and X-rays: LY-R cells are radio-resistant and hydrogen peroxide-sensitive, whereas LY-S cells are radiosensitive and hydrogen peroxide-resistant. Higher initial DNA breaks and higher iron content (potentially active in the Fenton reaction) were found in the hydrogen peroxide sensitive LY-R cells than in the hydrogen peroxide resistant LY-S cells, whereas the antioxidant defence of LY-R cells was weaker. In particular, catalase activity is twofold higher in LY-S than in LY-R cells. The content of monobromobimane-reactive thiols is 54% higher in LY-S than in LY-R cells. In contrast, the activity of glutathione peroxidase (GPx) is about two times higher in LY-R than in LY-S cells; however, upon induction with selenium the activity increases 15.6-fold in LY-R cells and 50.3-fold in LY-S cells. Altogether, the sensitivity difference is related to the iron content, the amount of the initial DNA damage, as well as to the efficiency of the antioxidant defence system. Differential nuclear translocation of p65-NF-kappaB in LY sublines is due to the more efficient antioxidant defence in LY-S than in LY-R cells.

Abstract
The L5178Y (LY) murine lymphoma sublines LY-R and LY-S are differentially sensitive to ionizing radiation. The high radiation sensitivity of LY-S cells is related to impaired rejoining of DNA double strand breaks. We found previously that the gamma-ray-induced base damage is higher in the more radiosensitive LY-S subline. Here, we examine the role of the repair of ionizing radiation induced base damage in relation to the radiosensitivity difference of these sublines. We used the GS/MS technique to estimate the repair rates of six types of base damage in gamma-irradiated LY cells. All modified DNA bases identified in the course of this study were typical for irradiated chromatin. The total amount of initial base damage was higher in the radiation sensitive LY-S subline than in the radiation resistant LY-R subline. The repair rates of 5-OHMeUra, 5-OHCyt, 8-OHAde were similar in both cell lines, the repair rates of FapyAde and 8-OHGua were higher in the radiosensitive LY-S cell line, whereas the repair of 5-OHUra was faster in its radioresistant counter, the LY-R. Altogether, the repair rates of the y-ray-induced DNA base damage in LY sublines are related neither to the initial amounts of the damaged bases nor to the differential lethal or mutagenic effects of ionizing radiation in these sublines.

Abstract
Because the toxicity of suicide gene therapeutics is directly related to basal promoter activity, we developed an assay to test for promoter "leakiness" using a diphtheria toxin mutant. Sequences of 15 prostate-specific gene promoter constructs were cloned in an expression plasmid (pBK; Stratagene, La Jolla, CA) backbone driving expression of an attenuated mutant of diphtheria toxin A (tox176). Low expression levels of the DT-tox176 result in significant protein synthesis inhibition reflected by a decreased expression of the luciferase activity of a simultaneously transfected CMV luciferase construct. ID50 (dose of plasmid with 50% luciferase inhibition) was calculated for each promoter construct in different cell lines. Highest transactivational activity (ID50 <75 ng) was found for the CMV promoter in all cell lines, which is in agreement with the dual luciferase assay findings. Unlike the dual luciferase findings, however, the DT-tox176 assay showed protein inhibition of CN65 (PSA promoter/enhancer) and PSE-hK2 (PSA enhancer and basal human kallikrein 2 promoter) in HEK293 and DLD cells indicating "leakiness" of these promoter constructs. Low basal promoter activity in nonprostate cell lines was found for the minimal PSA promoter, hK2, DD3, and OC promoters. The DT-tox176 assay can better predict basal promoter activity compared to less sensitive dual luciferase assay.

Abstract
There are numerous data suggesting that oxidative stress may be involved in the development of atherosclerosis. Therefore, in the present study we measured the amount of 8-hydroxy-2'-deoxyguanosine (8-OH-dG), one of the typical biomarkers of oxidative stress, in DNA isolated from lymphocytes of the patients and in the control group. Levels of antioxidant vitamins (A, C, and E) and intracellular labile iron pool (LIP), which can influence oxidative stress, were also determined. Blood samples were obtained from a control group of 55 healthy persons and from 43 atherosclerotic patients. 8-OH-dG and the vitamin levels were measured by high-performance liquid chromatography. Labile iron pool in lymphocytes was analyzed by fluorescent assay. The levels of 8-OH-dG and LIP were significantly higher and vitamin C concentration was significantly lower in the patient group than in the control group. The rest of the analyzed parameters do not significantly differ between the groups. A lower concentration of vitamin C and higher levels of labile iron pool in a group of atherosclerotic patients when compared with the control group may lead to oxidative stress, which is manifested by a higher level of 8-OH-dG in blood lymphocytes. All these factors may create an environment that promotes the development of atherosclerosis.

Abstract
The L5178Y (LY) murine lymphoma sublines LY-R and LY-S are differentially sensitive to ionizing radiation. The high radiation sensitivity of LY-S cells is related to impaired rejoining of DNA double strand breaks. We found previously that the gamma-ray-induced base damage is higher in the more radiosensitive LY-S subline. Here, we examine the role of the repair of ionizing radiation induced base damage in relation to the radiosensitivity difference of these sublines. We used the GS/MS technique to estimate the repair rates of six types of base damage in gamma-irradiated LY cells. All modified DNA bases identified in the course of this study were typical for irradiated chromatin. The total amount of initial base damage was higher in the radiation sensitive LY-S subline than in the radiation resistant LY-R subline. The repair rates of 5-OHMeUra, 5-OHCyt, 8-OHAde were similar in both cell lines, the repair rates of FapyAde and 8-OHGua were higher in the radiosensitive LY-S cell line, whereas the repair of 5-OHUra was faster in its radioresistant counter, the LY-R. Altogether, the repair rates of the y-ray-induced DNA base damage in LY sublines are related neither to the initial amounts of the damaged bases nor to the differential lethal or mutagenic effects of ionizing radiation in these sublines.

Abstract
We examined the response to hydrogen peroxide of two L5178Y (LY) sublines which are inversely cross-sensitive to hydrogen peroxide and X-rays: LY-R cells are radio-resistant and hydrogen peroxide-sensitive, whereas LY-S cells are radiosensitive and hydrogen peroxide-resistant. Higher initial DNA breaks and higher iron content (potentially active in the Fenton reaction) were found in the hydrogen peroxide sensitive LY-R cells than in the hydrogen peroxide resistant LY-S cells, whereas the antioxidant defence of LY-R cells was weaker. In particular, catalase activity is twofold higher in LY-S than in LY-R cells. The content of monobromobimane-reactive thiols is 54% higher in LY-S than in LY-R cells. In contrast, the activity of glutathione peroxidase (GPx) is about two times higher in LY-R than in LY-S cells; however, upon induction with selenium the activity increases 15.6-fold in LY-R cells and 50.3-fold in LY-S cells. Altogether, the sensitivity difference is related to the iron content, the amount of the initial DNA damage, as well as to the efficiency of the antioxidant defence system. Differential nuclear translocation of p65-NF-kappaB in LY sublines is due to the more efficient antioxidant defence in LY-S than in LY-R cells.

Abstract
Human umbilical cord blood (UCB) has been successfully used as a source of allogeneic hematopoietic cells for transplantation. Banking of the UCB requires its volume reduction to decrease storage space, costs and volume of infused DMSO. In order to select an optimal method for volume reduction we compared several methods of cord blood processing, namely buffy coat centrifugation, red cell lysis, hydroxyethyl starch (HES)-, methylcellulose- and gelatin-sedimentations. The viability of cells and the recoveries of total white blood cells, mononuclear cells and CD34+ cells was evaluated. We also compared the efficacy of red cells depletion from the original UCB sample. Buffy coat centrifugation, red cell lysis, HES, gelatin or methylcellulose resulted in high mononuclear cell recoveries, whereas high hematopoietic cell recovery was observed only after HES sedimentation and buffy coat processing. The HES sedimentation procedure compared to buffy coat processing is more time and labor consuming and resulted in higher red blood cell and platelets depletion. Both methods can be recommended as a method at choice for the umbilical cord blood processing before banking.

Abstract
Following the first successful cord blood transplantation in 1988, several hundreds of patients were treated using same protocol. The main limitation of the wide use of cord blood as a source of haematopoietic cells is the number of available units of this tissue. To make possible selection of HLA-matched cells for individual patient, several thousands of cord blood samples must be collected and stored in liquid nitrogen. The network of cooperating cord blood banks with join accessible database is necessary. In this paper the activity of Jose Carreras memorial Cord Blood Bank established in Warsaw was described. Since the middle of January the collection of cord blood units for clinical purposes was started. During first three months 80 samples of cord blood was collected. Collections were obtained from normal full-term deliveries after the third stage of labour. For the banking the collection over 60 ml or contain over 4 x 10(8) of mononuclear cells were qualified. Whole blood samples and plasma samples obtained following volume reduction were used for HLA and bacteriology tests. After volume reduction the number of nucleated cells (WBC), mononuclear cells (MNC) and hematopoietic cells (CD34+) were evaluated. After processing the cord blood samples were frozen using control freezer and were stored in liquid nitrogen storage tanks. According to results of cord blood transplantation hundred percent of banked samples are suitable for recipients weighing 10 kg and only 7 percent for these weighing 50 kg.

Abstract
The redox properties of iron make this metal a key participant in oxygen-mediated toxicity. Accordingly, L5178Y (LY) mouse lymphoma cell lines, which display a unique inverse cross-sensitivity to ionizing radiation (IR) and hydrogen peroxide (H(2)O(2)), are a suitable model for the study of possible differences in the constitutive control of intracellular iron availability. We report here that the level of iron in the cytosolic labile iron pool (LIP), ie, potentially active in the Fenton reaction, is more than 3-fold higher in IR-resistant, H(2)O(2)-sensitive (LY-R) cells than in IR-sensitive, H(2)O(2)-resistant (LY-S) cells. This difference is associated with markedly greater content of ferritin H-subunits (H-Ft) in LY-S than in LY-R cells. Our results show that different expression of H-Ft in LY cells is a consequence of an up-regulation of H-Ft mRNA in the LY-S mutant cell line. In contrast, posttranscriptional control of iron metabolism mediated by iron-responsive element-iron regulatory proteins (IRPs) interaction is similar in the 2 cell lines, although IRP1 protein levels in iron-rich LY-R cells are twice those in iron-deficient LY-S cells. In showing that LY cell lines exhibit 2 different patterns of intracellular iron regulation, our results highlight both the role of high LIP in the establishment of pro-oxidant status in mammalian cells and the antioxidant role of ferritin.

Abstract
We have previously found different proportions of iron and copper in nuclei of two sublines of murine lymphoma L5178Y (LY) and proposed a model of chromatin organization with these metal ions at the DNA attachment sites. We now examine the effect of chelators, desferal (DFO, iron-specific) and neocupreine (NEO, copper-specific) on DNA of LY-R and LY-S cells, using the comet and micronuclei frequency tests. There is less copper and more iron in LY-R nuclei than in LY-S nuclei. Accordingly, the effect of NEO is more marked in LY-R than in LY-S cells and in both sublines it is expressed as enhanced tail moment (measure of DNA damage in the comet assay) and increased micronuclei frequency. On the contrary, the effect of DFO on the tail moment is less pronounced in LY-R than in LY-S cells. With increasing DFO concentrations, there is a gradual decrease in the tail moment values below the control level in LY-S cells. In LY-R cells the tail moment values initially increase, then gradually decrease, eventually falling below the control level. This points to a dramatic conformational change that masks the effect of DNA discontinuities. The presence of the latter is indicated by the increase in micronuclei frequency. These results support the postulated differential role of iron and copper ions in maintaining the higher order DNA structure in LY sublines.

There was a statistically significant difference in the damage levels between the hazard and control group. In this paper we describe a confounding lack of effect of the smoking habit on the DNA damage in the tested groups. The genotoxic effect of the smoking habit, as well as its modifying effect on genome damage inflicted by other agents, have been firmly established. However, no statistically significant effect of smoking was found in our study, neither in the control nor in the hazard group. This lack of effect was seen in all DNA damage determinations, both direct (DNA strand breakage and alkali-labile lesions) and enzyme-combined (base damage) and did not depend on the comet parameters, which were taken as damage indicators.

Abstract
The role of nuclear proteins in protection of DNA against ionizing radiation and their contribution to the radiation sensitivity was examined by an alkaline version of comet assay in two L5178Y (LY) mouse lymphoma cell lines differing in sensitivity to ionizing radiation. LY-S cells are twice more sensitive to ionizing radiation than LY-R cells (D0 values of survival curves are 0.5 Gy and 1 Gy, respectively). Sequential removal of nuclear proteins by extraction with NaCl of different concentrations increased the X-ray induced DNA damage in LY-R nucleoids. In contrast, in the radiation sensitive LY-S cell line, depletion of nuclear proteins practically did not affect DNA damage. Although there is no doubt that the main cause of LYS cells' sensitivity to ionizing radiation is a defect in the repair of double-strand breaks, our data support the concept that nuclear matrix organisation may contribute to the cellular susceptibility to DNA damaging agents.

Abstract
Radiosensitive L5178Y-S (LY-S) subline and its parental, more radioresistant L5178Y-R (LY-R) subline differ in DNA double strand break (DSB) rejoining. In this work we examined by comet assay the repair of X-ray-induced DNA damage in LY cells treated with OK-1035, a potent DNA-PK inhibitor. The unirradiated cells differ: the respective tail moment values for LY-R and LY-S cells were 9.62+/-2.84 and 3.52+/-0.1, reflecting the susceptibility to lysis conditions as well as the possible endogenous (oxidative) damage level. The level of initial DNA damage measured after irradiation (8 Gy) at DNA-denaturing pH was the same in both LY sublines: the mean tail moment values +/- SD were 92.93+/-10.39 for LY-R cells and 94.93+/-12.94 for LY-S cells. In LY-S cells the repair of 8 Gy X-ray-induced damage proceeded identically in the presence or absence of 2 mM OK-1035 to the same level of residual damage. In contrast, the level of residual damage in inhibitor treated LY-R cells was considerably higher than that in the untreated cells. Moreover, the inhibitor affected LY-R cells in G1 and S phases and not those in G2, in agreement with cell-cycle specificity of DNA-PK. These results may indicate that the DSB repair defect previously identified in LY-S cells is due to a lack of function of DNA-PK or its impaired activation in the irradiated cells.

Abstract
We examined a group of people professionally at risk of exposure to low doses of ionizing radiation (altogether 49 individuals). Age, use of therapeutic drugs, work-related exposure to hazardous agents, previous exposures to diagnostic X-rays, such as patient and nuclear medical examination, were registered. For each individual, the occupational radiation burden received over the past period of 5 years was taken from the official personal records based on film dosimetry controlled every month. A matched group of controls was chosen among the administrative employees (40 individuals). The mean age of the studied population at the time of blood sampling was 49 years (range 24-69). The individuals were divided into groups according to risk of exposure and sex. The alkaline comet assay was used to measure DNA breaks and alkali-labile sites. We compared the mean tail moments, tail length and percentage of DNA in the tail. There was a significant difference between the control and hazard groups in DNA damage. Higher DNA damage was also found for men than for women in the control group. There was no relation of DNA damage to age either in control or hazard group. Additionally, analysis of distributions of tail moment values pointed to a considerable individual diversity even in the control group. Therefore, further investigations were necessary into the suitability of the comet assay as a biological dosimetry method; the results obtained so far warrant such investigations.

Szumiel, Application of the comet assay for monitoring DNA damage in workers exposed to chronic low dose irradiation. I. Strand breakage., Mutat. Res. 416 (1998) 21-35], we reported the results of DNA damage examination carried out for a group of people (49 individuals) professionally at risk of exposure to low doses of ionizing radiation as measured by the alkaline comet assay. Here, we used the method in combination with oxidative base damage-specific endonucleases to estimate base damage in the same individuals. These were endonuclease III (endoIII) and formamidopyrimidine glycosylase (FPG). In contrast to the previous investigations, we found no statistically significant difference in base damage between the control and hazard groups. Interestingly, the hazard group exhibited lower level of enzyme-sensitive sites than the control; however, this different was not significant. No correlation of base damage with age was found, similarly as in the case of DNA damage measured by the alkaline comet assay. Interindividual variability of base damage precluded exposure estimation for single individuals, since several members of the control group exhibited high comet parameters.

Abstract
Seven oxidized DNA bases were quantified, by gas GC/MS-SIM, in chromatin from gamma-rays and H2O2 treated mouse lymphoma L5178Y (LY) cells, inversely cross-sensitive to these agents. In H2O2 treated cells (2 mM, 1 h, 37 degrees C) we found more damage in LY-R cells than in LY-S cells. On the contrary, in gamma-rays (400 Gy) treated cells we found more damaged DNA bases in LY-S cells. The yield of damaged bases in control cells was similar in both cell lines, with the exception of 8OHAde and FapyGua that were found at a much higher level in LY-S cells. The yields of damaged bases were related to cellular sensitivity to damaging agent; this observation points to a relationship between DNA base damage induction, antioxidant defense system in the intracellular milieu and cell sensitivity.

Abstract
The cytotoxicity and mutagenicity of three organic platinum(II) complexes 1-3 have been studied in two strains of murine lymphoma L5178Y cells. (1) [Pt(Amp)Cl] (S,N,N) (Amp, ampicillin); (2) [Pt(Met(O))Cl2] (S,N), (met(O), L-methionine sulfoxide); (3) [Pt(Met(O))(R-IDA)] (S,N) [N,N), (R-IDA, 2,4-N-(dimethylacetanilide)-iminodiacetic acid). It has been confirmed that the cytotoxic and mutagenic action of Pt-complexes depends on the structure of stable ligand and the number and structure of the leaving groups. The highest cytotoxicity and mutagenicity was found in cells treated with the dichloromethioninesulfoxideplatinum(II) complex.

Abstract
Irradiation of human lymphocytes (1 cGy X rays, 37 degrees C) or their treatment with 10 microM hydrogen peroxide (30 min at 37 degrees C) evoked a ca 30% decrease in the frequency of micronuclei upon subsequent X-irradiation (1.5 Gy). The response was reflected in a lower micronuclei frequency, but no change in DNA repair rate was observed as measured by the comet assay, directly after the challenge dose. Treatment of lymphocytes with staurosporine, an inhibitor of protein kinases, or with TMB-8, a calcium antagonist, carried out in parallel with the adaptive dose prevented the development of the adaptive response measured as micronuclei frequency. In lymphocytes that were staurosporine- or TMB-8-treated and irradiated under adaptive conditions showed that the rate of DNA repair was not changed. We conclude that treatment with agents that interfere with the transduction of the signal triggered by the low dose prevents the development of the adaptive response induced by X rays or hydrogen peroxide. Lower chromosome damage revealed by the cytokinesis block-micronuclei test in the adapted lymphocytes is unrelated to DNA repair rate as measured by comet assay.

Abstract
Using a radioresistant subline of murine lymphoma cells L5178(R) DNA damages, their repair and the process of second DNA degradation in dynamics following X-radiation (5 Gy), and in the distant cell progeny have been studied by the method of DNA-comet assay (the alcaline conditions). The repair of DNA damages was found to be finished by 6 h, and by 18 h the second DNA-degradation was observed. The cell progeny was followed throughout 30 generations, with the enhancement of sensitivity to repeat irradiation, and the decrease in repair rate and degree of the second DNA degradation being registered. In the population of the 30th generation, the lack of the second DNA degradation was observed. If the second DNA degradation is indicative of apoptosis, as it is generally considered in literature, it can be supposed that in the distant progeny of irradiated L5178Y(R) cells radiation induces no programmed cell death and is not a trigger of apoptosis.

Abstract
Two sublines of L5178Y (LY) murine lymphoma, differing in sensitivity to hydrogen peroxide, served as a cellular model for examination of the antioxidant defense system. The contribution of catalase, glutathione peroxidase (G-Px) and glutathione were evaluated. Sensitivity to 3-amino-1,2,4-triazole (AMT), inhibitor of catalase, was higher in LY-R (hydrogen peroxide sensitive) than in LY-S (hydrogen peroxide resistant) cells. Accordingly, activity of catalase was twofold lower in LY-R than in LY-S cells. G-Px activity was about two times higher in LY-R than in LY-S cells. After induction with selenium it increased 15.6 times in LY-R cells and 50.3 times in LY-S cells. Reduced glutathione (GSH) content (and possibly other monobromobimane-reactive thiols) were determined fluorimetrically with monobromobimane and fluorescence found 54% higher in LY-S than in LY-R cells. Inhibition of catalase caused GSH decrease in LY-S cells; this decrease was abrogated by inducing G-Px by selenium treatment. On the contrary, in LY-R cells inhibition of catalase decreased GSH content only slightly and selenium treatment did not further change the GSH level. DNA damage (estimated by "comet" assay) was the same in hydrogen peroxide-treated cells in the presence or absence of AMT; however, after induction of G-Px by selenium, DNA damage was considerably lowered. This sparing effect of selenium was accompanied by decreased growth inhibition in selenium pretreated, hydrogen peroxide-treated cell cultures.

Abstract
Irradiation of human lymphocytes (1 cGy X-rays, 37 degrees C) evoked an approximately 30% decrease in the frequency of micronuclei upon subsequent X-irradiation (1.5 Gy). The response was reflected in a lower micronucleus frequency but not in the DNA repair rate measured by the comet assay directly after the challenge dose. Treatment of lymphocytes with anti-CD38 antibody 1 h before irradiation with the adaptive dose prevented the development of the adaptive response measured as micronuclei frequency, but adaptation was not reflected in a lower rate of DNA repair, measured by the alkaline version of the 'comet' assay. In lymphocytes that were anti-CD38-treated and irradiated and or irradiated with the adaptive dose the rate of DNA repair was not changed. However, the mean DNA damage level in adapted anti-CD38-treated lymphocytes was significantly lower than that in the control lymphocytes at all time points. We conclude that ligation of CD38 by antibody initiates signalling that prevents the development of the adaptive response induced by X-rays. Lower chromosome damage revealed by the cytokinesis block-micronucleus test in the adapted lymphocytes is unrelated to DNA repair rate.

Abstract
The L5178Y (LY) murine lymphoma subline, LY-R, is more radioresistant and more sensitive to camptothecin (CPT, inhibitor of topisomerase I) than the second subline used in our investigation, LY-S. Post-irradiation treatment with 3 microM CPT enhanced the radiosensitivity of LY-S cells (D0 decrease from 0.52 to 0.34 Gy), but did not change it in LY-R cells. Treatment with 2 mM benzamide [BZ, inhibitor of poly (ADP-ribosylation)] before x-rays and CPT increased the radiosensitivity of LY-R cells (D0 decrease from 1.15 to 0.52) without further modification of radiosensitivity of LY-S cells. Activity of topoisomerase I was diminished 10 min after x-irradiation (5 Gy) in LY-S, but not in LY-R cells. The data on DNA damage (fluorescent halo or comet assays) showed that the ultimate fate of the cells did not depend on the DNA damage pattern estimated immediately after treatment (e.g. the damage was greater in x-rays plus CPT than in BZ plus x-rays plus CPT treated LY-R cells, although the radiosensitivity was less). Aphidicolin (inhibitor of DNA polymerases alpha and delta) applied concomitantly with CPT in cells not pretreated with BZ prevented the increase in DNA damage in LY-R cells, but was without effect in LY-S cells. Taking into account the differential inhibition by x-rays of DNA synthesis in LY sublines and its reversion by BZ in LY-S but not in LY-R cells, we conclude that the pattern of DNA damage observed by the methods applied depended on the status of DNA replication.

Abstract
Cells from the L5178Y murine lymphoma subline LY-R are twice as resistant to killing by ionizing radiation than the subline LY-S. In contrast, LY-R cells are more sensitive to killing by H2O2, the effect being more pronounced at 37 degrees C than 0 degree C. Initial DNA damage after H2O2 treatment (both temperatures, 5 min) has been estimated by the 'comet' assay (single-cell gel electrophoresis) and fluorescent halo technique. According to both methods, the initial damage is significantly higher in LY-R cells, particularly that inflicted at 0 degree C. Differences between DNA unwinding and rewinding abilities at pH 9 and 6.9 (estimated by the fluorescent halo technique) point to a considerable difference in pH-9-labile damage between the sublines, as observed previously for x-irradiated cells (Kapiszewska et al. 1992). In contrast to findings with x-irradiated cells, however, after H2O2 treatment this damage is more extensive in LY-R cells than in LY-S cells. Thus, the initial pH-9-labile damage corresponds to the pattern of sensitivity to H2O2 and x-rays. We suggest that this is caused by different proportions of cuprous and ferric ions found in the nuclei of LY sublines and by the different ability of these ions to react with H2O2 and water radiolysis products. The copper/iron ratio in the nucleus is 1.31 in LY-R cells and 4.84 in LY-S cells.

Abstract
The L5178Y murine lymphoma subline LY-R is twofold more resistant to killing by ionizing radiation than the subline LY-S. In contrast, LY-R cells are more sensitive to killing by hydrogen peroxide: at 37 degrees C LY-R cells are 1.4 times more sensitive to the killing effect of H2O2 than LY-S cells. Pretreatment with the iron chelator desferroxamine followed by hydrogen peroxide treatment at 37 degrees C gives a considerable sparing effect, which is substantially greater for the LY-R subline than for the LY-S subline. This is reflected in the initial DNA damage (estimated by single cell gel electrophoresis), survival and mutation frequency in the HGPRT locus. Similar results have been obtained with calcium chelators, which, according to recent findings (Sandström and Granström 1993), also are efficient iron chelators. In contrast, the response to X-rays is not modified by the above chelators, with the exception of mutation frequencies: lower mutant numbers are found in desferroxamine pretreated LY-R cells.
