AB  - Aim: Newly synthesized platinum(IV) complexes with ethylenediamine-N,N’-diacetate ligands (EDDA-type) (butyl-Pt and pentyl-Pt) were investigated against two cancer (A549 lung, and HTB 140 melanoma) and one non-cancerous (MRC-5 embryonic lung fibroblast) human cell lines. Materials and Methods: The effects of these agents were compared with those of cisplatin after 6-, 24- and 48-h treatment. Sulforhodamine-B (SRB) assay was performed to estimate the cytotoxic effect, while the inhibitory effect on cell proliferation was measured using 5-bromo-2,-deoxyuridine (BrdU) incorporation assay. Cell cycle analysis was performed by flow cytometry. Type of cell death induced by these agents was determined by electrophoretic analysis of DNA, flow cytometry and by western blot analysis of proteins involved in induction of apoptosis. The effects of gamma irradiation, alone and in combination with platinum-based compounds, were examined by clonogenic and SRB assays. Results: All examined platinum-based compounds had inhibitory and antiproliferative effects on A549 cells, but not on HTB140 and MRC-5 cells. Butyl-Pt, pentyl-Pt and cisplatin arrested the cell cycle in the S-phase and induced apoptotic cell death via regulation of expression of B-cell lymphoma 2 (BCL2) and BCL2-associated X (BAX) proteins. Platinum-based compounds increased the sensitivity of A549 cells to gamma irradiation. Butyl-Pt and pentyl-Pt showed better antitumour effects against A549 cells than did cisplatin, by interfering in cell proliferation and the cell cycle, and by triggering apoptosis. Conclusion: The effects of gamma irradiation on tumour cells may be amplified by pre-treatment of cells with platinum-based compounds.

AB  - The aim of the present study was to investigate effects of pomegranate peel (PP) extract on different human cancer cell lines. MTT was performed to estimate cytotoxic effects of PP extract against HTB140, HTB177, MCF7, HCT116 human cancer cell lines and MRC-5 normal fibroblasts. Clonogenic assay was used to reveal cell survival after the treatment with PP extract. Cell cycle analysis was done using flow cytometry. Wound healing assay was applied to estimate inhibitory effects of PP extract on migration of cancer cells. The results showed that PP extract expressed selective cytotoxicity for cancer cells compared to normal cell line. Analyzed cancer cell lines displayed individual variations in sensitivity to PP extract reflected through changes in clonogenic survival, cell cycle distribution and migration, which may be due to the specific nature of each tested cell line. In conclusion, PP extract exhibits good inhibitory effects on tested cancer cell lines.

AB  - Purpose: Investigation of effects on DNA of γ-irradiated human cancer cells pretreated with free radical scavengers is aimed to create reference data which would enable assessment of the relative efficiency of high linear energy transfer (LET) radiations used in hadron therapy, i.e. protons and carbon ions. Materials and methods: MCF-7 breast and HTB177 lung cancer cells are irradiated with γ-rays. To minimize indirect effects of irradiation, dimethyl sulfoxide (DMSO) or glycerol are applied as free radical scavengers. Biological response to irradiation is evaluated through clonogenic cell survival, immunocytochemical and cell cycle analysis, as well as expression of proteins involved in DNA damage response. Results: Examined cell lines reveal similar level of radioresistance. Application of scavengers leads to the rise of cell survival and decreases the number of DNA double strand breaks in irradiated cells. Differences in cell cycle and protein expression between the two cell lines are probably caused by different DNA damage repair mechanisms that are activated. Conclusion: The obtained results show that DMSO and glycerol have good scavenging capacity, and may be used to minimize DNA damage induced by free radicals. Therefore, they will be used as the reference for comparison with high LET irradiations, as well as good experimental data suitable for validation of numerical simulations. © 2019, © 2019 Taylor & Francis Group, LLC.

AB  - Background: Obesity, diabetes, and associated diseases are increasing all over the world, and pose a great burden on public health. According to the latest reports, 440 million people are suffering from diabetes. Diabetes is caused by impaired ability to produce or respond to the hormone insulin consequently resulting in hyperglycemia. Methods: Data used for this review was obtained by using PUBMED/MEDLINE (1987-2018). The main data search terms were: Gentiana lutea, Gentiana lutea extract, Gentiana lutea constituents, obesity, diabetes mellitus, diabetic complications. Results: In the present review, we describe the potential of root powder of yellow gentian (Gentiana lutea) for the prevention of obesity and diabetes including complications related to this disease. Conclusion: Reasonably effective, low-cost alternatives could fulfill an important role for a large part of the human population and could be of great value for the food market. Even a modest reduction of morbidity and mortality with respect to this disease translates into millions of lives saved. © 2019 Bentham Science Publishers.

AB  - In this study we evaluate apoptosis time window of primary fibroblasts treated with cold atmospheric plasma (CAP), power range 0.4-1.4 W, for 30 sec, using γ-H2AX phosphorylation assay and flow cytometry. In contrast to irradiation where maximum of γ-H2AX foci appeared 30 min after irradiation and apoptosis 24 h later irrespective of radiation dose, treatment with CAP (power of 0.4 and 0.6) induces maximum of γ-H2AX foci 2 h after treatment. Apoptosis occurred in a power-dependent manner, with time shift of 2-3 h. Besides power-dependent time shift in apoptosis induction, apoptosis time window is the same and lasts for 2 h. © 2019, Indian Academy of Sciences.

AB  - The study of cell proliferation is a useful tool in the fields of toxicology, pathophysiology and pharmacology. Cell proliferation and its degree can be evaluated using 5-bromo-2deoxyuridine which is incorporated into the newly synthesized DNA. The aim of this study was the optimization of subcutaneous application of 5-bromo-2-deoxyuridine implantation for continuous and persistent marking of proliferating cells in the rat forestomach. 3-tert-Butyl-4-hydroxyanisole was used as the agent that ensures cell proliferation. In order to determine the optimal dose for proliferating cells labeling, 5-bromo-2-deoxyuridine doses of 50 mg, 100 mg, 200 mg or 350 mg were implemented 2 days prior to sacrifice by flat-faced cylindrical matrices. Immunohistochemical analysis using 5-bromo-2-deoxyuridine in situ detection kit was performed for the detection of 5-bromo-2-deoxyuridine labeled cells. The results showed that for adult rats, the optimum 5-bromo-2-deoxyuridine dose is 200 mg per animal for subcutaneous application. The here described manner of 5-bromo-2-deoxyuridine in vivo labeling provides a simple, efficient, and reliable method for cell labeling, and at the same minimizes stress to animals.

abstract = "The study of cell proliferation is a useful tool in the fields of toxicology, pathophysiology and pharmacology. Cell proliferation and its degree can be evaluated using 5-bromo-2deoxyuridine which is incorporated into the newly synthesized DNA. The aim of this study was the optimization of subcutaneous application of 5-bromo-2-deoxyuridine implantation for continuous and persistent marking of proliferating cells in the rat forestomach. 3-tert-Butyl-4-hydroxyanisole was used as the agent that ensures cell proliferation. In order to determine the optimal dose for proliferating cells labeling, 5-bromo-2-deoxyuridine doses of 50 mg, 100 mg, 200 mg or 350 mg were implemented 2 days prior to sacrifice by flat-faced cylindrical matrices. Immunohistochemical analysis using 5-bromo-2-deoxyuridine in situ detection kit was performed for the detection of 5-bromo-2-deoxyuridine labeled cells. The results showed that for adult rats, the optimum 5-bromo-2-deoxyuridine dose is 200 mg per animal for subcutaneous application. The here described manner of 5-bromo-2-deoxyuridine in vivo labeling provides a simple, efficient, and reliable method for cell labeling, and at the same minimizes stress to animals.",

AB  - The aim of this study was to investigate effects of irradiations with the therapeutic proton and carbon ion beams in two non-small cell lung cancers, CRL5876 adenocarcinoma and HTB177 large cell lung carcinoma. The DNA damage response dynamics, cell cycle regulation, and cell death pathway activation were followed. Viability of both cell lines was lower after carbon ions compared to the therapeutic proton irradiations. HTB177 cells showed higher recovery than CRL5876 cells seven days following the treatments, but the survival rates of both cell lines were lower after exposure to carbon ions with respect to therapeutic protons. When analyzing cell cycle distribution of both CRL5876 and HTB177 cells, it was noticed that therapeutic protons predominantly induced G1 arrest, while the cells after carbon ions were arrested in G2/M phase. The results illustrated that differences in the levels of phosphorylated H2AX, a double-strand break marker, exist after therapeutic proton and carbon ion irradiations. We also observed dose- and time-dependent increase in the p53 and p21 levels after applied irradiations. Carbon ions caused larger increase in the quantity of p53 and p21 compared to therapeutic protons. These results suggested that various repair mechanisms were induced in the treated cells. Considering the fact that we have not observed any distinct change in the Bax/Bcl-2 ratio following irradiations, it seemed that different types of cell death were involved in the response to the two types of irradiations that were applied.

AB  - We studied the colloidal TiO2 nanoparticles as a carrier for controlled delivery of the ruthenium complex to the melanoma cell line. The system demonstrated slower complex release upon visible and increased release rate upon UV light illumination. Accordingly, the light-dependent cytotoxicity of the system was demonstrated on amelanotic melanoma cancer line. The cell death is enhanced by UV and reduced by red light in the presence of investigated nanocomposite system. Both components of the system may act as photosensitizers, by generating reactive oxygen species, which promote cell death. Thus, the system might act dually, as photodynamic therapeutic agent and as the light tunable system for metallo-drug delivery and it might be of interest for development of new more efficient drug delivery approaches by using a light as external stimulus.

AB  - Fanconi anemia is rare inherited disease characterized by wide spectrum of congenital anomalies, progressive pancytopenia, and predisposition to hematological malignancies and solid tumors. Molecular genetic analysis of mutations in FANC genes is of a great importance for diagnosis confirmation, prenatal and carrier testing, as well as for prediction of chemotherapy outcome and disease complications. In this study we performed screening of frequently affected regions of FANCD2 gene for sequence variants in six unrelated FA-D2 patients in Serbia. This is the first molecular analysis of FANCD2 gene in Serbian FA-D2 patients. A total of 10 sequence variants were detected, one in homozygous, and nine in heterozygous state. Two variants were found within exons, and eight within introns, in deep intronic regions. In-silico analysis showed that among all detected variants one exon variant and three intron variants might have impact on splicing mechanism. Heterozygous variants found in intron 3, c. 206-246delG; exon 26, c. 2396 C GT A and intron 28, c. 2715+573 C GT T were not previously reported. In-silico analysis revealed that among them, two (intron 3, c. 206-246 delG and exon 26, c. 2396 C GT A) could be novel disease-causing mutations. Many variants were found in more than one patient, including those unreported, indicating their possible ethnic association. Great number of variants in some patients suggests their non-random emergence in Fanconi anemia pathway.

AB  - In most patients with lung cancer radiation treatment is used either as single agent or in combination with radiosensitizing drugs. However, the mechanisms underlying combined therapy and its impact on different modes of cell death have not yet been fully elucidated. We aimed to examine effects of single and combined treatments with gamma-rays and erlotinib on radioresistant CRL-5876 human lung adenocarcinoma cells with particular emphasis on cell death. CRL-5876 cells were treated with gamma-rays and/or erlotinib and changes in cell cycle, DNA repair dynamics, ultrastructure, nuclear morphology and protein expression were monitored at different time points. To reveal the relationship between types of cell death that arise after these treatments, autophagy was blocked with chloroquine. We found that higher dose of gamma-rays causes G2/M arrest while adding of erlotinib to this treatment decreases the number of cells in S phase. Impact of erlotinib on kinetics of disappearance of irradiation-induced DNA double strand breaks is reflected in the increase of residual gamma-H2AX foci after 24 h. gamma-rays provoke cytoprotective autophagy which precedes development of senescence. Erlotinib predominantly induces apoptosis and enlarges the number of apoptotic cells in the irradiated CRL-5876 cells. Chloroquine improved cytotoxicity induced by radiation and erlotinib, increased apoptosis and decreased senescence in the CRL-5876 cells. The results obtained on CRL-5876 cells indicate significant radiosensitizing effect of erlotinib and suggest that chloroquine in the combination with the above treatments may have an additional antitumor effect in lung adenocarcinoma.

AB  - Background and objectives: The main goal when treating malignancies with radiation is to deprive tumour cells of their reproductive potential. One approach is to induce tumour cell apoptosis. This study was conducted to evaluate the ability of carbon ions (C-12) to induce apoptosis and cell cycle arrest in human HTB140 melanoma cells. Methods: In this in vitro study, human melanoma HTB140 cells were irradiated with the 62 MeV/n carbon (C-12) ion beam, having two different linear energy transfer (LET) values: 197 and 382 keV/mu m. The dose range was 2 to 16 Gy. Cell viability was estimated by the sulforhodamine B assay seven days after irradiation. The cell cycle and apoptosis were evaluated 48 h after irradiation using flow cytometry. At the same time point, protein and gene expression of apoptotic regulators were estimated using the Western blot and q-PCR methods, respectively. Results: Cell viability experiments indicated strong anti-tumour effects of C-12 ions. The analysis of cell cycle showed that C-12 ions blocked HTB140 cells in G2 phase and induced the dose dependent increase of apoptosis. The maximum value of 21.8 per cent was attained after irradiation with LET of 197 keV/mu m at the dose level of 16 Gy. Pro-apoptotic effects of C-12 ions were confirmed by changes of key apoptotic molecules: the p53, Bax, Bcl-2, poly ADP ribose polymerase (PARP) as well as nuclear factor kappa B (NF kappa B). At the level of protein expression, the results indicated significant increases of p53, NF kappa B and Bax/Bcl-2 ratio and PARP cleavage. The Bax/Bcl-2 mRNA ratio was also increased, while no change was detected in the level of NF kappa B mRNA. Interpretation and conclusions: The present results indicated that anti-tumour effects of C-12 ions in human melanoma HTB140 cells were accomplished through induction of the mitochondrial apoptotic pathway as well as G2 arrest.

AB  - Ionizing radiation induces DNA double strand breaks (DSBs) that trigger phosphorylation of the histone protein H2AX (gamma H2AX). Immunofluorescent staining visualizes formation of gamma H2AX foci, allowing their quantification. This method, as opposed to Western blot assay and Flow cytometry, provides more accurate analysis, by showing exact position and intensity of fluorescent signal in each single cell. In practice there are problems in quantification of gamma H2AX. This paper is based on two issues: the determination of which technique should be applied concerning the radiation dose, and how to analyze fluorescent microscopy images obtained by different microscopes. HTB140 melanoma cells were exposed to gamma-rays, in the dose range from 1 to 16 Gy. Radiation effects on the DNA level were analyzed at different time intervals after irradiation by Western blot analysis and immunofluorescence microscopy. Immunochemically stained cells were visualized with two types of microscopes: AxioVision (Zeiss, Germany) microscope, comprising an ApoTome software, and AxioImagerA1 microscope (Zeiss, Germany). Obtained results show that the level of gamma H2AX is time and dose dependent. Immunofluorescence microscopy provided better detection of DSBs for lower irradiation doses, while Western blot analysis was more reliable for higher irradiation doses. AxioVision microscope containing ApoTome software was more suitable for the detection of gamma H2AX foci.

AB  - Background: Fanconi anemia (FA) is a chromosomal instability syndrome characterized by increased frequency of chromosomal breakages, chromosomal radial figures and accelerated telomere shortening. In this work we performed detailed molecular-cytogenetic characterization of breakpoints in primary lymphocytes of FA-D2 patients in different stages of the disease using fluorescent in situ hybridization. Results: We found that chromosomal breakpoints co-localize on the molecular level with common fragile sites, whereas their distribution pattern depends on the severity of the disease. Telomere quantitative fluorescent in situ hybridization revealed that telomere fusions and radial figures, especially radials which involve telomere sequences are the consequence of critically shortened telomeres that increase with the disease progression and could be considered as a predictive parameter during the course of the disease. Sex chromosomes in FA cells are also involved in radial formation indicating that specific X chromosome regions share homology with autosomes and also could serve as repair templates in resolving DNA damage. Conclusions: FA-D2 chromosomal breakpoints co-localize with common fragile sites, but their distribution pattern depends on the disease stage. Telomere fusions and radials figures which involve telomere sequences are the consequence of shortened telomeres, increase with disease progression and could be of predictive value.

AB  - Fanconi anemia (FA) is a rare genetically heterogeneous disorder associated with bone marrow failure, birth defects and cancer susceptibility. Apart from the disease-causing mutations in FANC genes, the identification of specific DNA variations, such as single nucleotide polymorphisms (SNPs), in other candidate genes may lead to a better clinical description of this condition enabling individualized treatment with improvement of the prognosis. In this study, we have assessed 95 SNPs located in 52 key genes involved in base excision repair (BER), nucleotide excision repair (NER), mismatch repair (MMR), double strand break (DSB) repair and cell cycle control using a DNA repair chip (Asper Biotech, Estonia) which includes most of the common variants for the candidate genes. The SNP genotyping was performed in five FA-D2 patients and in one FA-A patient. The polymorphisms studied were synonymous (n=10), nonsynonymous (missense) (n=52) and in non-coding regions of the genome (introns and 5 and 3 untranslated regions (UTR)) (n=33). Polymorphisms found at the homozygous state are selected for further analysis. Our results have shown a significant inter-individual variability among patients in the type and the frequency of SNPs and also elucidate the need for further studies of polymorphisms located in ATM, APEX APE 1, XRCC1, ERCC2, MSH3, PARP4, NBS1, BARD1, CDKN1B, TP53 and TP53BP1 which may be of great importance for better clinical description of FA. In addition, the present report recommends the use of SNPs as predictive and prognostic genetic markers to individualize therapy of FA patients.

AB  - Introduction: Proton radiation offers physical advantages over conventional radiation. Radiosensitivity of human 59M ovarian cancer and HTB140 melanoma cells was investigated after exposure to gamma-rays and protons. Material and methods: Irradiations were performed in the middle of a 62 MeV therapeutic proton spread out Bragg peak with doses ranging from 2 to 16 Gy. The mean energy of protons was 34.88+/-2.15 MeV, corresponding to the linear energy transfer of 4.7+/-0.2 keV/mu m. Irradiations with gamma-rays were performed using the same doses. Viability, proliferation and survival were assessed 7 days after both types of irradiation while analyses of cell cycle and apoptosis were performed 48 h after irradiation. Results: Results showed that gamma-rays and protons reduced the number of viable cells for both cell lines, with stronger inactivation achieved after irradiation with protons. Surviving fractions for 59M were 0.91+/-0.01 for gamma-rays and 0.81+/-0.01 for protons, while those for HTB140 cells were 0.93+/-0.01 for gamma-rays and 0.86+/-0.01 for protons. Relative biological effectiveness of protons, being 2.47+/-0.22 for 59M and 2.08+/-0.36 for HTB140, indicated that protons provoked better cell elimination than gamma-rays. After proton irradiation proliferation capacity of the two cell lines was slightly higher as compared to gamma-rays. Proliferation was higher for 59M than for HTB140 cells after both types of irradiation. Induction of apoptosis and G2 arrest detected after proton irradiation were more prominent in 59M cells. Conclusions: The obtained results suggest that protons exert better antitumour effects on ovarian carcinoma and melanoma cells than gamma-rays. The dissimilar response of these cells to radiation is related to their different features.

The mean energy of protons was 34.88+/-2.15 MeV, corresponding to the linear energy transfer of 4.7+/-0.2 keV/mu m. Irradiations with gamma-rays were performed using the same doses. Viability, proliferation and survival were assessed 7 days after both types of irradiation while analyses of cell cycle and apoptosis were performed 48 h after irradiation. Results: Results showed that gamma-rays and protons reduced the number of viable cells for both cell lines, with stronger inactivation achieved after irradiation with protons. Surviving fractions for 59M were 0.91+/-0.01 for gamma-rays and 0.81+/-0.01 for protons, while those for HTB140 cells were 0.93+/-0.01 for gamma-rays and 0.86+/-0.01 for protons. Relative biological effectiveness of protons, being 2.47+/-0.22 for 59M and 2.08+/-0.36 for HTB140, indicated that protons provoked better cell elimination than gamma-rays. After proton irradiation proliferation capacity of the two cell lines was slightly higher as compared to gamma-rays. Proliferation was higher for 59M than for HTB140 cells after both types of irradiation. Induction of apoptosis and G2 arrest detected after proton irradiation were more prominent in 59M cells. Conclusions: The obtained results suggest that protons exert better antitumour effects on ovarian carcinoma and melanoma cells than gamma-rays. The dissimilar response of these cells to radiation is related to their different features.",

AB  - We use human primary fibroblasts for comparing plasma and gamma rays induced DNA damage. In both cases, DNA strand breaks occur, but of fundamentally different nature. Unlike gamma exposure, contact with plasma predominantly leads to single strand breaks and base-damages, while double strand breaks are mainly consequence of the cell repair mechanisms. Different cell signaling mechanisms are detected confirming this (ataxia telangiectasia mutated - ATM and ataxia telangiectasia and Rad3 related - ATR, respectively). The effective plasma doses can be tuned to match the typical therapeutic doses of 2Gy. Tailoring the effective dose through plasma power and duration of the treatment enables safety precautions mainly by inducing apoptosis and consequently reduced frequency of micronuclei.

AB  - Fluence, depth absorbed dose and linear energy transfer (LET) distributions of proton and carbon ion beams have been investigated using the Monte Carlo code Geant4 (GEometry ANd Tracking). An open source application was developed with the aim to simulate two typical transport beam lines, one used for ocular therapy and cell irradiations with protons and the other for cell irradiations with carbon ions. This tool allows evaluation of the primary and total dose averaged LET and predict their spatial distribution in voxelized or sliced geometries. In order to reproduce the LET distributions in a realistic way, and also the secondary particles contributions due to nuclear interactions were considered in the computations. Pristine and spread-out Bragg peaks were taken into account both for proton and carbon ion beams, with the maximum energy of 62 MeV/n. Depth dose distributions were compared with experimental data, showing good agreement. Primary and total LET distributions were analysed in order to study the influence of contributions of secondary particles in regions at different depths. A non-negligible influence of high-LET components was found in the entrance channel for proton beams, determining the total dose averaged LET by the factor 3 higher than the primary one. A completely different situation was obtained for carbon ions. In this case, secondary particles mainly contributed in the tail that is after the peak. The results showed how the weight of light and heavy secondary ions can considerably influence the computation of LET depth distributions. This has an important role in the interpretation of results coming from radiobiological experiments and, therefore, in hadron treatment planning procedures.

AB  - Molecular targeted cancer therapy is a promising treatment strategy. Considering the central role of the epidermal growth factor receptor in cell proliferation and survival, there are indications that targeted agents like tyrosine kinase inhibitors, i. e., erlotinib, may enhance the antitumor treatment by radiation. The aim of this study is to analyze the inactivation effects of gamma-rays and to test the radiosensitizing potential of erlotinib on human lung adenocarcinoma cells in vitro. Irradiations were performed with doses ranging from 1 Gy to 8 Gy. In order to increase the radiosensitivity of CRL-5876 lung adenocarcinoma cells, the cells were treated with a clinically relevant concentration of 2 mu M erlotinib. The effects of single and combined treatments were monitored using clonogenic survival, cell viability and proliferation assays at different time points. For the detection and visualization of the phosphorylated histone H2AX (gamma-H2AX), an important biological marker of DNA double-strand break formation, fluorescence inununocytochemistry, was performed. The response to the treatment was monitored at four time points: 30 min, 2, 6, and 24 h. Irradiations with gamma-rays resulted in significant cell inactivation regarding all analyzed biological endpoints. Combined treatments revealed consistent cell inactivation. Moreover, compared to gamma-rays alone, elevated levels of gamma-H2AX foci were observed after pretreatment with erlotinib, indicating radiosensitization through impaired DNA repair.

AB  - Purpose: As the Fanconi anemia (FA) pathway is required for appropriate cell cycle progression through mitosis and the completion of cell division, the aim of the present study was to determine the destiny of FA cells after irradiation in vitro and to elucidate any difference in radiosensitivity between FA and control cells. Materials and methods: Analyses of phosphorylated histone H2AX (gamma-H2AX) foci, micronuclei formation and cell cycle analysis were performed in unirradiated (0 min) and irradiated primary FA fibroblasts and in a control group at different post-irradiation times (30 min, 2 h, 5 h and 24 h). Results: The accumulation of gamma-H2AX foci in irradiated FA fibroblasts was observed. At 24 h post-irradiation, 57% of FA cells were gamma-H2AX foci-positive, significantly higher than in the control (p LT 0.01). The cell cycle analysis has shown the transient G2/M arrest in irradiated FA fibroblasts. The portion of cells in the G2/M phase showed initial increase at 30 min post-irradiation and afterwards decreased over time reaching the pretreatment level 24 h after irradiation. Irradiated FA fibroblasts progressed to abnormal mitosis, as is shown by the production of cells with different nuclear morphologies from binucleated to multinucleated surrounded with micronuclei, and also by a high percentage of foci-positive micronuclei. The majority of radiation-induced micronuclei were gamma-H2AX foci-positive, indicating that radiation-induced micronuclei contain fragments of damaged chromosomes. In contrast, in the control group, most of the micronuclei were classified as gamma-H2AX foci-negative, which indicates that cells with unrepaired damage were blocked before entering mitosis. Conclusion: The results clearly indicate that mitotic catastrophe might be an important cell-death mechanism involved in the response of FA fibroblasts to ionizing radiation.

AB  - To investigate genetic subtypes of inherited bone marrow failure syndrome Fanconi anemia (FA) in Sebia. FA-D2 subtype was found to be the most frequent genetic subtype among investigated FA patients; specific observations of FA-D2 phenotype are pointed out. Several biological endpoints of FA cells in vitro such as radiation-induced level of lymphocyte micronuclei (radiosensitivity), base line and radiation induced level of the DNA double strand breaks (DSBs), leukocyte apoptosis, and telomere capping function were assessed. The results indicate that all FA-D2 patients display radioresistant in vitro response, which is seen as significantly reduced yield of radiation-induced micronuclei. On the contrary, FA-A patients display radiosensitive in vitro response seen as increased number of radiation-induced micronuclei (MN). A massive elimination of irradiated cells via apoptosis is found in both FA-A and FA-D2 subtypes. In FA-A subtype apoptosis positively relates with the yield of radiation-induced MN, whereas in FA-D2 subtype apoptosis relates with a high percentage of cells carrying dysfunctional telomeres. The present results unequivocally demonstrate that cytokinesis-block micronucleus (CBMN) assay and analyses of telomere capping function can be used to distinguish FA-D2 and FA-A complementation groups. Considering all biological endpoints were analyzed, it can be concluded that all FA patients are radiosensitive, regardless of their complementation group. Thus, using CBMN test and telomere capping function analysis can discriminate FA-A from FA-D2 complementation groups, which could be important for assessment the conditioning regimens prior to bone marrow transplantation.

AB  - An extensive number of pathologies are associated with mitochondrial dysfunction (MDF) and oxidative stress (OS). Thus, mitochondrial cofactors termed mitochondrial nutrients (MN), such as alpha-lipoic acid (ALA), Coenzyme Q10 (CoQ10), and L-carnitine (CARN) (or its derivatives) have been tested in a number of clinical trials, and this review is focused on the use of MN-based clinical trials. The papers reporting on MN-based clinical trials were retrieved in MedLine up to July 2014, and evaluated for the following endpoints: (a) treated diseases; (b) dosages, number of enrolled patients and duration of treatment; (c) trial success for each MN or MN combinations as reported by authors. The reports satisfying the above endpoints included total numbers of trials and frequencies of randomized, controlled studies, i.e., 81 trials testing ALA, 107 reports testing CoQ10, and 74 reports testing CARN, while only 7 reports were retrieved testing double MN associations, while no report was found testing a triple MN combination. A total of 28 reports tested MN associations with classical antioxidants, such as antioxidant nutrients or drugs. Combinations of MN showed better outcomes than individual MN, suggesting forthcoming clinical studies. The criteria in study design and monitoring MN-based clinical trials are discussed.

AB  - Herbal preparation Chlamyfin was investigated for its total polyphenol content, 2,2-diphenyl-1picrylhydrazyl (DPPH) scavenging activity, and anti-inflammatory and genotoxic properties. A high total polyphenol content provided evidence of high DPPH radical scavenging activity (IC50 = 4.96 +/- 0.23 mu g/ml). Analysis of the electrochemical behavior of Chlamyfin indicated high reducing ability, i.e., high antioxidant capacity, in agreement with the DPPH test. Analysis of myeloperoxidase (MPO) inhibition by Chlamyfin suggested anti-inflammatory action (IC50 values of 5.40 mu g/ml and 4.45 i_tg/m1 for an incubation time of 10 and 30 min, respectively). For genotoxic assessment, oxidative stress was induced by irradiation of peripheral whole blood with gamma-radiation in vitro. In the presence of Chlamyfin, reduced incidence of micronuclei without disturbance to the proliferative potential of cells was evidenced in both irradiated and unirradiated samples, indicating its genoprotective properties. It was shown that Chlamyfm, in addition to its bactericidal effect, also possesses strong antioxidant, anti-inflammatory and anti-genotoxic properties.

AB  - Fanconi anemia (FA) is a rare genetic disease associated with deficiencies in DNA repair pathways. A body of literature points to a pro-oxidant state in FA patients, along with evidence for oxidative stress (OS) in the FA phenotype reported by in vitro, molecular, and animal studies. A highlight arises from the detection of mitochondrial dysfunction (MDF) in FA cell lines of complementation groups A, C, D2, and G. As yet lacking, in vivo studies should focus on FA-associated MDF, which may help in the understanding of the mitochondrial basis of OS detected in cells and body fluids from FA patients. Beyond the in vitro and animal databases, the available analytical devices may prompt the direct observation of metabolic and mitochondrial alterations in FA patients. These studies should evaluate a set of MDF-related endpoints, to be related to OS endpoints. The working hypothesis is raised that, parallel to OS, nitrosative stress might be another, so far unexplored, hallmark of the FA phenotype. The expected results may shed light on the FA pathogenesis and might provide grounds for pilot chemoprevention trials using mitochondrial nutrients. (C) 2013 Elsevier Inc. All rights reserved.
