Abstract
Cytostatic drugs are one of the most important therapeutic options for cancer, a disease that is expected to affect 29 million individuals by 2040. After being excreted, cytostatics reach wastewater treatment plants (WWTPs), which are unable to efficiently remove them, and consequently, they will be released into the aquatic environment. Due to the highly toxic properties of cytostatics, it is particularly relevant to evaluate their potential ecological risk. Yet, cytostatics toxicity data is still not available for various species. In this work, the ecotoxicity of two widely consumed cytostatics, cyclophosphamide (CYP-as a model cytostatic) and mycophenolic acid (MPA-as a priority cytostatic), was evaluated on three freshwater species-Raphidocelis subcapitata, Brachionus calyciflorus, and Danio rerio, and the risk quotient (RQ) was assessed. Both drugs significantly affected the yield and growth inhibition of the microalgae, while for rotifers, the least sensitive species, only significant effects were registered for CYP. These drugs also caused significant effects on the mortality and morphological abnormalities on zebrafish. The estimation of the RQ discloses that CYP seems to pose a low risk to aquatic biota while MPA poses a very high risk. Altogether, these results emphasize the need for more complete environmental risk assessments, to properly prioritize and rank cytostatics according to their potentially toxic effects on the environment and aquatic biota.

Metabolite Profiling Analysis and the Correlation with Biological Activity of Betalain-Rich Portulaca grandiflora Hook. Extracts. Antioxidants (Basel) 2022; 11:antiox11091654. [PMID: 36139728 PMCID: PMC9495615 DOI: 10.3390/antiox11091654] [Citation(s) in RCA: 0] [Impact Index Per Article: 0] [Reference Citation Analysis] [Abstract] [Key Words] [Track Full Text] [Download PDF] [Figures] [Journal Information] [Subscribe] [Scholar Register] [Received: 08/08/2022] [Revised: 08/19/2022] [Accepted: 08/20/2022] [Indexed: 11/25/2022] Open
Abstract
The aim of the study was to evaluate the possible correlation between the bioactivity and the phytochemical profile of four betalain-rich extracts from Portulaca grandiflora Hook. The HPLC-DAD-ESI-MS analysis indicated the presence of 19 betaxanthins and two betacyanins. The highest concentrations of betaxanthins (982 mg/100 g DE) and betacyanins (650 mg/100 g DE) were noticed in orange and purple flowers extracts, respectively. The HPLC-DAD-ESI-HRMS/MS analyses revealed the presence of a total of 71 compounds. Fifteen new betaxanthins and fifty other metabolites were identified for the first time. The antioxidant activity of the studied flower extracts increased in the sequence of yellow < orange < purple < red (0.066−0.176 mM TE/g DE). Betalains showed less effect on the antioxidant activity of extracts than other metabolites did. Extracts from yellow and orange flowers were more active against Gram-positive bacteria (MIC = 4−16 mg/L), whereas extracts from red and purple flowers were slightly more active against Gram-negative bacteria (MIC = 16−32 mg/L). All the extracts showed the same activity against yeasts (MIC = 32 mg/L). Betaxanthins were active against Gram-positive bacteria, whereas betacyanins were active against Gram-negative bacteria. Remaining metabolites also exhibited antimicrobial activities. The cytotoxicity assessment showed that the P. grandiflora extracts were non-toxic to normal VERO cells. No significant antiviral activity towards Human Herpesvirus type 1 was observed (62 µg/mL). Among the tested varieties, the purple one showed anticancer selectivity towards colon carcinoma cells (RKO).

Abstract
The objective of this study was to investigate the effect of polysaccharides from Ostrea rivularis (ORP) relieving reproductive damage by regulating autophagy. The results showed that ORP intervention could alleviate the pathological changes of the testis and alleviate oxidative stress which were caused by cyclophosphamide (CTX) in vivo, including improve sperm symptoms and rise testosterone level. Reduced level of autophagy after ORP intervention was observed by transmission electron microscopy (TEM), which implied that ORP might regulate cell autophagy. In vitro experiments showed that ORP could alleviate the damage of TM4 cells induced by H2O2, reduce the level of intracellular ROS and the content of MDA. Autophagy-related protein expressions of p62, LC3, Beclin-1 before and after 3-MA inhibitor intervention were also proved that ORP could regulate autophagy. Overall, these results confirmed that ORP could reduce reproductive damage related to autophagy.

Abstract
Chlorothalonil is a fungicide widely used in agriculture as well as an active ingredient in antifouling paints. Although it causes toxic effects on non-target organisms and can accumulate in fish tissues, little is known about its sublethal effects. Thus, genotoxic and mutagenic effects of intraperitoneal injected chlorothalonil in Micropogonias furnieri, an estuarine fish of frequent human consumption and a promising test-organism for ecotoxicological assays, were assessed. Chlorothalonil showed to be genotoxic (DNA damage by comet assay) and mutagenic (micronuclei, nuclear buds, apoptotic fragments, and bilobed cells) even at the lowest dose tested (0.35 μg g-1) and in a dose-dependent manner (0.35 and 3.5 μg g-1) for micronuclei, apoptotic fragments, and bilobed cells. As genomic instability may lead to carcinogenesis, the present evidence can assist decision-makers in banning this compound since any benefit toward food production is outweighed by the hazard to aquatic ecosystems and human health.

Abstract
Abstract
Background
Cyclophosphamide (CP) is an anti-neoplastic alkylating agent that is extensively used in different chemotherapy regimens. Adverse effects on the reproductive system, especially spermatogenesis, are one of the most important side effects of this drug. It is medically essential to use complementary and alternative drugs. Herbal drugs have long been used as a complementary treatment. Our purpose was to study the effect of hydroalcoholic Allium atroviolaceum L. extract on spermatogenesis in CP-treated mice.
Results
CP affected a significant decrease in sperm count, motility, viability, and morphology. Sperm count was significantly higher in the all extract groups than in the group of control (p<0.001) and CP group (p<0.001, p<0.01). Sperm motility was significantly greater in the extract (100 and 200mg/kg) groups than in the group of control (p<0.05 and <0.001). Sperm immotility and rotational movement were significantly higher in the CP group than in the CP+extract groups (p<0.001). The sperm viability was significantly greater in the CP+extract (200mg/kg) group than in the CP group (p<0.001). The number of headless sperm, sperm with initial tail, with coiled tail, and sperm with curved body, was significantly lower in the CP+extract (200mg/kg) group than in the CP group (p<0.001).
Conclusion
A. atroviolaceum extract treatment significantly improved CP-induced reproductive toxicity.

Abstract
STUDY QUESTION What are the fertility outcomes of male and female childhood acute lymphoblastic leukaemia (ALL) long-term survivors? SUMMARY ANSWER We observed similar fertility outcomes in both male and female childhood ALL survivors compared with the general population, with the exception of a higher proportion of miscarriages among partners of male survivors. WHAT IS KNOWN ALREADY Survival after childhood ALL is currently >90% and fertility impairments are among the main concerns of the long-term survivors. Few studies have focused on the fertility issues within this selected population and the existing data are difficult to interpret due to the different treatment regimens received by the patients, the small sample sizes and the unavailability of control data in many studies. STUDY DESIGN, SIZE, DURATION Childhood ALL patients enrolled in European Organisation for Research and Treatment of Cancer (EORTC) studies between 1971 and 1998 in France and Belgium, <18 years old at diagnosis and alive and ≥18 years at follow-up were eligible. Among 1418 eligible survivors, 507 (35.8%) participated (277 females, 230 males). Controls from the general population matched one to one by age, province, level of urbanization and sex could be identified for 503 survivors. PARTICIPANTS/MATERIALS, SETTING, METHODS Survivors and controls were invited to fill out a questionnaire including information about their menstrual cycles (for females), intention to have children, having children, use of medical help to become pregnant and occurrence of negative pregnancy outcomes (birth defect, miscarriage, medical abortion or stillbirth). The results were analysed separately for females and males. The association between age at diagnosis and fertility outcomes, adjusted by age at follow-up, study and country were investigated using logistic regression. MAIN RESULTS AND THE ROLE OF CHANCE The median time since diagnosis was 20.1 years and the median age at follow-up was 25 years. There were 144 survivors (97 females, 47 males) who wanted to have children. Among these, craniospinal radiotheraphy (CRT) and haematopoietic stem cell transplantation (HSCT) were administered to 18% and 4%, respectively. Of these who tried to have children, 75% of females and 69% of males succeeded, compared with 72% and 61% of the controls, respectively. These differences were not statistically significant (P = 0.73 for females and P = 0.50 for males). Overall, fertility outcomes were comparable between survivors and controls, except that a higher proportion of miscarriages occurred in partners of male survivors (28.1% versus 5.9%, P = 0.021). Among female survivors, an older age at diagnosis (10-17 years) was associated with a greater risk of pregnancy problems (adjusted OR 5.61, P = 0.046). LIMITATIONS, REASONS FOR CAUTION The interpretation of the incidence of miscarriage among the partners of male survivors is limited by the lack of data regarding the males' partners and by a possibly higher tendency to recall and disclose fertility issues among male survivors compared with male controls. WIDER IMPLICATIONS OF THE FINDINGS Fertility outcomes were similar in childhood ALL survivors and controls, and the low proportion of patients treated with CRT or HSCT might explain this. Further studies should confirm the higher proportion of miscarriages in partners of male survivors.

Cyclophosphamide enhances the antitumor potency of GITR engagement by increasing oligoclonal cytotoxic T cell fitness. JCI Insight 2021; 6:151035.

Abstract
Only a subset of cancer patients responds to checkpoint blockade inhibition in the clinic. Strategies to overcome resistance are promising areas of investigation. Targeting glucocorticoid-induced tumor necrosis factor receptor-related protein (GITR) has shown efficacy in preclinical models, but GITR engagement is ineffective in controlling advanced, poorly immunogenic tumors, such as B16 melanoma, and has not yielded benefit in clinical trials. The alkylating agent cyclophosphamide (CTX) depletes regulatory T cells (Tregs), expands tumor-specific effector T cells (Teffs) via homeostatic proliferation, and induces immunogenic cell death. GITR agonism has an inhibitory effect on Tregs and activates Teffs. We therefore hypothesized that CTX and GITR agonism would promote effective antitumor immunity. Here we show that the combination of CTX and GITR agonism controlled tumor growth in clinically relevant mouse models. Mechanistically, we show that the combination therapy caused tumor cell death, clonal expansion of highly active CD8+ T cells, and depletion of Tregs by activation-induced cell death. Control of tumor growth was associated with the presence of an expanded population of highly activated, tumor-infiltrating, oligoclonal CD8+ T cells that led to a diminished TCR repertoire. Our studies show that the combination of CTX and GITR agonism is a rational chemoimmunotherapeutic approach that warrants further clinical investigation.

Abstract
Metastatic progression and tumor recurrence pertaining to TNBC are certainly the leading cause of breast cancer-related mortality; however, the mechanisms underlying TNBC chemoresistance, metastasis, and tumor relapse remain somewhat ambiguous. TNBCs show 77% of the overall 4-year survival rate compared to other breast cancer subtypes (82.7 to 92.5%). TNBC is the most aggressive subtype of breast cancer, with chemotherapy being the major approved treatment strategy. Activation of ABC transporters and DNA damage response genes alongside an enrichment of cancer stem cells and metabolic reprogramming upon chemotherapy contribute to the selection of chemoresistant cells, majorly responsible for the failure of anti-chemotherapeutic regime. These selected chemoresistant cells further lead to distant metastasis and tumor relapse. The present review discusses the approved standard of care and targetable molecular mechanisms in chemoresistance and provides a comprehensive update regarding the recent advances in TNBC management.

Abstract
Cyclophosphamide is an antitumor agent that causes disorders in fertility. This study aimed to evaluate the protective effects of Spirulina platensis against Cyclophosphamide-induced testicular toxicity. 42 male Wistar rats were randomly divided into six groups. Experimental groups included three groups. The first experimental group received Cyclophosphamide at a dose of 5 mg/kg body weight (BW) orally. The second and third experimental groups received 5 mg/kg BW Cyclophosphamide and 500 and 1,000 mg/kg BW S. platensis orally, respectively. The control groups included a control group, and two S. platensis control groups. Following 28 days, two flow cytometry techniques were used to determine sperm apoptosis and testicular protein expression of tumor protein (p53) and B-cell lymphoma 2 (Bcl-2). p53 is a tumor suppressor protein that causes the cell to enter the apoptosis cycle after DNA damage and Bcl-2 is an anti-apoptotic protein that acts through the mitochondrial pathway of apoptosis. FITC-Annexin V assay was used for sperm apoptosis evaluation. For protein expression assay, primary and secondary antibodies staining were performed. The Cyclophosphamide group showed a significant increase in sperm apoptosis compared to the control group. Cyclophosphamide significantly increased p53 and decreased Bcl-2 expression compared to the control group. S. platensis co-treated groups exhibited a significant decrease in sperm apoptosis compared to the Cyclophosphamide group. Moreover, S. platensis co-treated groups displayed a significant decreasing in p53 and increasing in Bcl-2 expression compared to the Cyclophosphamide group. The results of this study indicated that S. platensis protected rats against Cyclophosphamide-induced reproductive toxicity. PRACTICAL APPLICATIONS: Cyclophosphamide is the chemotherapy agent used to treat different cancers. Cyclophosphamide has side effects on the male reproductive system. Spirulina plantesis has a protective effect because of its antioxidant and anti-apoptotic properties. Co-administration of Spirulina plantesis with Cyclophosphamide reduces sperm apoptosis also decreases P53 protein expression and increases Bcl-2 protein expression. This study validated the anti-apoptotic potential of Spirulina plantesis against Cyclophosphamide-induced male reproductive toxicity.

Abstract
Korean herbal formulation, MYOMI-14, has been reported to improve the idiopathic male infertility condition with poor semen. In this study, four MYOMI formulations were modified from MYOMI-14 by reducing the number of constituents. We investigated the therapeutic effect of MYOMI formulations on cyclophosphamide-induced male infertility using mice model. Cyclophosphamide treatment significantly decreased body weight, testicular weight, sperm count, normal-shaped sperm rate and sperm motility compared to untreated control group, whereas MYOMI formulations restore the cyclophosphamide-induced dysfunction, as determined by increased sperm count and motility, and decreased abnormally shaped spermatozoa. In addition, treatment with MYOMI formulations reduced cyclophosphamide-induced apoptosis of germ cells and oxidative stress. MYOMI-treated mice also showed improved spermatogenesis as shown by the increased expression of spermatogenesis-related genes, as cAMP-responsive element modulator (CREM) and cAMP response element-binding (CREB) protein. Among the MYOMI formulations, MYOMI-7 showed better results in terms of recovering CP-induced damages to testis and improving the fertility. Taken together, this study is expected to make significant contribution to the literature by exploring various formulations that reduced constituents of MYOMI-14, a Korean herbal medicine, in treating CP-induced male infertility.

Abstract
Taste buds in the oral cavity have a complex immune system regulating normal functions and inflammatory reactions. Cyclophosphamide (CYP), a chemotherapy drug, has wide-ranging disruptive effects on the taste system including loss of taste function, taste sensory cells, and capacity for taste cell renewal. In bladder epithelium, CYP also induces inflammation. To determine if CYP induces inflammation in taste buds, we used immunohistochemistry to examine tumor necrosis factor alpha (TNF-α) (a proinflammatory cytokine) expression over a 72-hour period. Expression of TNF-α increased in a subset of PLCβ2 labeled (Type II) cells, but not SNAP-25 labeled (Type III) cells, between 8 and 24 h postinjection and declined slowly thereafter. This inflammatory response may play an important role in the disruptive effects of CYP on the taste system. Further, pretreatment with amifostine, a sulfhydryl drug known to protect normal tissues during chemo- or radiation therapy, reduced the amount of CYP-induced TNF-α expression in taste buds, suggesting this drug is capable of protecting normal cells of the taste system from adverse effects of CYP. Amifostine, used as a pretreatment to CYP and possibly other chemotherapy drugs, may offer clinical support for preventing negative side effects of chemotherapy on the taste system.

Cytotoxic responses of the anticancer drug cyclophosphamide in the mussel Mytilus galloprovincialis and comparative sensitivity with human cells lines. CHEMOSPHERE 2020; 261:127678. [PMID: 32717509 DOI: 10.1016/j.chemosphere.2020.127678] [Citation(s) in RCA: 1] [Impact Index Per Article: 0.3] [Reference Citation Analysis] [Abstract] [Key Words] [MESH Headings] [Track Full Text] [Subscribe] [Scholar Register] [Received: 03/13/2020] [Revised: 07/08/2020] [Accepted: 07/09/2020] [Indexed: 06/11/2023]
Abstract
The rise of cancer cases worldwide led to an increase in production and consumption of anticancer drugs, that ultimately end up in the marine environment and are accumulated in aquatic organisms. Cyclophosphamide (CP) is a cytotoxic alkylating agent frequently prescribed in cancer treatments. This study assess ecotoxicological effects of CP on mussels Mytilus galloprovincialis, through in vivo and ex vivo approaches and compares the sensitivity of mussel haemocytes with well-established human cell lines (RPE and HeLa). Mussels were exposed in vivo to CP (1000 ng L-1) and several biomarkers analysed in gills and digestive glands namely neurotoxicity (AChE activity), oxidative stress (GPx activity), biotransformation (GST activity), lipid peroxidation (LPO) and apoptosis (caspase activity), whereas genotoxicity was determined in mussels' haemocytes. Cytotoxicity was also assessed in haemocytes (in vivo and ex vivo) and human cell lines (in vitro) exposed to a range of CP concentrations (50, 100, 250, 500 and 1000 ng L-1) over 24 h, via neutral red assay. In in vivo exposure, detoxification of CP did not efficiently occur in the gills while in digestive glands GPx and GST activities were induced, jointly with a decrease in lipid peroxidation, indicating a potential outcome of the protective antioxidant mechanisms, whereas no apoptosis was noted. Moreover, cytotoxicity and DNA damage were detected in haemocytes. The ex vivo exposure haemocytes to CP caused cytotoxicity (from 100 ng L-1), whereas no effects occurred in human cell lines. This suggests that, at relevant environmental concentrations, CP cause subtle and irreversible impacts on M. galloprovincialis.

Abstract
Chemo brain, a constellation of cognitive deficiencies followed by chemotherapy drugs, used to treat different types of cancers and adversely impacts the quality of life of a cancer survivor. The underlying mechanism of chemo brain remains vague, thus delaying the advancement of efficient treatments. Unfortunately, there is no US FDA approved medicine for chemo brain and often medicines considered for chemo brain are already the ones approved for other diseases. Nevertheless, researches exploring stem cell transplantation in different neurodegenerative diseases demonstrate that cellular transplantation could reverse chemotherapy-induced chemo brain. This review talks about the mechanism behind the cognitive impairments instigated by different chemotherapy drugs used in cancer treatment, and how stem cell therapy could be advantageous to overcome this disease.

Abstract
Objective Researchers have confirmed that chronic administration of drugs at high doses causes genotoxicity which serve as first step in development of cancers. Apremilast, a phosphodiesterase-4 inhibitor is Food and Drug Administration (FDA) approved drug for Psoriatic Arthritis. The present study designed to conduct genotoxicity testing using the genotoxic study which give simple, sensitive, economical and fast tools for the assessment of damage of genetic material. Methods To conduct genotoxicity study of Apremilast, 60 Swiss albino male mice divided into 6 groups (n = 10). Group1 served as a normal control group without any treatment, Group 2 treated as a disease control and administered with cyclophosphamide 40 mg/kg, IP. Group 3, 4, 5 and 6 treated as test groups and received 10, 20, 40 and 80 mg/kg/day Apremilast respectively. The total duration of study was 13 weeks. At termination day animals were sacrificed and chromosomal aberration assay (BMCAA) and micronucleus assay (BMMNA) were performed to know the genotoxicity potential of Apremilast. Results The results indicates significant rise in chromosomal aberrations (CA) frequency in bone marrow cells and decrease in the MI of the disease control animals as well as Apremilast treated groups. Further significant (p < 0.001; p < 0.0001) increase in score of micronucleated polychromatic erythrocytes (MNPCEs) and percentage of micronucleated PCEs per 1000 PCEs and decrease in the ratio of polychromatic/normochromatic erythrocytes (PCE/NCE) was observed in micronucleus assay. Genotoxic effect increases with the increase of Apremilast dose. Conclusion: Finding of present indicates that Apremilast shows genotoxic potential on high administration although further detailed toxicity studies required for confirmations.

Abstract
OBJECTIVE To develop an evidence-based guideline on contraception, assisted reproductive technologies (ART), fertility preservation with gonadotoxic therapy, use of menopausal hormone replacement therapy (HRT), pregnancy assessment and management, and medication use in patients with rheumatic and musculoskeletal disease (RMD). METHODS We conducted a systematic review of evidence relating to contraception, ART, fertility preservation, HRT, pregnancy and lactation, and medication use in RMD populations, using Grading of Recommendations Assessment, Development and Evaluation methodology to rate the quality of evidence and a group consensus process to determine final recommendations and grade their strength (conditional or strong). Good practice statements were agreed upon when indirect evidence was sufficiently compelling that a formal vote was unnecessary. RESULTS This American College of Rheumatology guideline provides 12 ungraded good practice statements and 131 graded recommendations for reproductive health care in RMD patients. These recommendations are intended to guide care for all patients with RMD, except where indicated as being specific for patients with systemic lupus erythematosus, those positive for antiphospholipid antibody, and/or those positive for anti-Ro/SSA and/or anti-La/SSB antibodies. Recommendations and good practice statements support several guiding principles: use of safe and effective contraception to prevent unplanned pregnancy, pre-pregnancy counseling to encourage conception during periods of disease quiescence and while receiving pregnancy-compatible medications, and ongoing physician-patient discussion with obstetrics/gynecology collaboration for all reproductive health issues, given the overall low level of available evidence that relates specifically to RMD. CONCLUSION This guideline provides evidence-based recommendations developed and reviewed by panels of experts and RMD patients. Many recommendations are conditional, reflecting a lack of data or low-level data. We intend that this guideline be used to inform a shared decision-making process between patients and their physicians on issues related to reproductive health that incorporates patients' values, preferences, and comorbidities.

Abstract
Genotoxicity and carcinogenicity profiles of drugs occasionally vary across species due to species difference in drug metabolic profile. To clarify the effect of species differences in the metabolic profile on micronucleus induction, we conducted an in vitro micronucleus test for seven clastogens (benzo[a]pyrene: BaP, cyclophosphamide monohydrate: CPA coumarin, diclofenac, piroxicam, lansoprazole, and chlorpheniramine) with rat, mouse, monkey, dog, or human liver S9. BaP, CPA, coumarin, diclofenac, piroxicam, and lansoprazole induced micronucleus formation with all species of S9s, whereas chlorpheniramine did not induce micronucleus formation in any of the S9s. BaP and CPA revealed remarkable species differences in micronucleus induction, whereas coumarin, diclofenac, piroxicam, and lansoprazole did not present any differences. Interestingly, the amounts of hydroxy-BaP-epoxides and phosphamide mustard, which might be associated with micronucleus induction by BaP and CPA, respectively, were correlated with the degree of micronucleus induction among the five species. In conclusion, the species difference in micronucleus induction by BaP and CPA was attributable to the differences in the metabolic profiles of these drugs among species. Our results indicate that it is crucial to understand the effect of species differences in the metabolic profile of drug candidates on genotoxicity and carcinogenicity potential and to predict their risk in human.

BRCA1 Promoter Methylation Status in 1031 Primary Breast Cancers Predicts Favorable Outcomes Following Chemotherapy. JNCI Cancer Spectr 2019; 4:pkz100.

Abstract
Background Breast Cancer 1 gene (BRCA1) is known to be inactivated in breast tumors by promoter methylation. Tumor cells in patients carrying a germline mutation in BRCA1 are sensitive to cytotoxic drugs that cause DNA double strand breaks. However, very little is known on whether patients with BRCA1 promoter methylated tumors are similarly sensitive to cytotoxic drugs. In this study, we address this by making use of extensive follow-up data on patients treated with cyclophosphamide, methotrexate, and fluorouracil in Iceland between 1976 and 2007. Methods We analyzed BRCA1 promoter methylation by pyrosequencing DNA from tumor samples from 1031 patients with primary breast cancer. Of those, 965 were sporadic cases, 61 were BRCA2, and five were BRCA1 germline mutation carriers. All cases were examined with respect to clinicopathological parameters and breast cancer–specific survival in patients treated with cytotoxic drugs. Information on chemotherapy treatment in noncarriers was available for 26 BRCA1 methylated tumors and 857 unmethylated tumors. Results BRCA1 was promoter methylated in 29 sporadic tumors or in 3.0% of cases (29 of 965), whereas none of the tumors derived from BRCA germline mutation carriers were promoter methylated. Important to note, patients with BRCA1 promoter methylation receiving chemotherapeutic drug treatment show highly improved breast cancer–specific survival compared with unmethylated controls (hazard ratio = 0.10, 95% confidence interval = 0.01 to 0.75, two-sided P = .02). Conclusions BRCA1 promoter methylation is predictive of improved disease outcome in patients receiving cyclophosphamide, methotrexate, and fluorouracil drug treatment. Our results support the use of markers indicative of “BRCAness” in sporadic breast cancers to identify patients that are likely to benefit from the use of DNA-damaging agents.

Abstract
The genotoxic potential of glucocorticoid receptor (GR)-targeted liposomal formulations of the anticancer drug molecule ESC8 was studied in vivo. A methodical literature review discovered no previous studies on the genotoxicity of ESC8. Genotoxicity was assessed in both male and female mice by various assay systems, such as comet assay, chromosomal aberrations and micronuclei assay, which detect different abnormalities. Eleven groups of male mice and eleven groups of female mice, containing six animals per group, were used in the present study: group I served as vehicle control; group II received the positive control (cyclophosphamide 40 mg/kg; CYP); and animals in group III to XI received free drug (ESC8), DX liposome and drug-associated DX liposomal formulation (DXE), respectively, dissolved in 5% solution of glucose at a drug-dose of 1.83, 3.67 and 7.34 mg/kg, respectively. Same drug treatments were followed for the female mice groups. The obtained data revealed the safety of DXE, which did not show substantial genotoxic effects at different dose levels. In contrast, the positive control, CYP, exhibited highly substantial irregular cytogenetic variations in comparison with the control group in different assays.

Abstract
Chemotherapy is one of the most common treatments for cancer; however, a side effect is often altered taste. This study examined how cyclophosphamide, a chemotherapy drug, affects salt taste in mice. On the basis of previous findings, it was predicted that cyclophosphamide-induced disruptions in salt taste would be observed near days 2-4, 8-12, and 22-24 posttreatment, and that multiple, smaller doses would cause more severe disruptions to taste. To test these predictions, two experiments were performed, one using brief access testing to measure appetitive qualities, and another using operant conditioning to measure detection thresholds. After a single 100 mg/kg cyclophosphamide injection, peak alterations in brief access lick rates were seen near days 5-8 and 15 posttreatment, whereas peak alterations in detection thresholds were seen days 6, 14, and 20 posttreatment. After five 20 mg/kg injections of cyclophosphamide, brief access lick rates revealed disruptions only on postinjection day 8 whereas thresholds appeared to cycle, gradually increased to and decreased from peak elevations on posttreatment days 4, 10, 15, 20, and 23. Although salt taste functions were disrupted by cyclophosphamide, the patterns of these disruptions were less severe and shorter than expected from cell morphology studies, suggesting a functional adjustment to maintain behavioral accuracy. Fractionation of cyclophosphamide dosing had minimum effect on brief access responses but caused longer, cyclic-like disruptions of detection thresholds compared to single-dose administration.

Abstract
This study investigated both the mutagenicity and anti-mutagenicity of alpha-lipoic acid (ALA) in the bone marrow cells of mice using a chromosomal aberration assay. Cyclophosphamide (CP) 40 mg/kg was used as a clastogen in the positive control, and a vehicle-treated negative control group was also included. Multiple dose levels (15, 30, and 100 mg/kg of ALA) were given by intraperitoneal injection (IP) alone and in combination with CP (CP was administered 1 h prior to ALA). Bone marrow samples were collected 12 and 24 h after drug administration. The results demonstrated a significant increase in the frequency of chromosomal aberrations (CA) in bone marrow cells with depressions in the mitotic index (MI) of the positive control group of mice. However, in the groups of mice treated with different doses of ALA in the presence of CP, the percentages of CA decreased significantly with increases in mitotic activity. The results also indicate that ALA given alone in different doses had no mutagenic effect on mouse bone marrow cells. ALA has a dose and time-dependent protective effect against the mutagenicity induced by CP.

Abstract
Chemotherapy often causes side effects that include disturbances in taste functions. Cyclophosphamide (CYP) is a chemotherapy drug that, after a single dose, elevates murine taste thresholds at times related to drug-induced losses of taste sensory cells and disruptions of proliferating cells that renew taste sensory cells. Pretreatment with amifostine can protect the taste system from many of these effects. This study compared the effects of a single dose (75 mg/kg) of CYP with effects generated by fractionated dosing of CYP (5 doses of 15 mg/kg), a dosing approach often used during chemotherapy, on the taste system of mice using immunohistochemistry. Dose fractionation prolonged the suppressive effects of CYP on cell proliferation responsible for renewal of taste sensory cells. Fractionation also reduced the total number of cells and the proportion of Type II cells within taste buds. The post-injection time of these losses coincided with the life span of Type I and II taste cells combined with lack of replacement cells. Fractionated dosing also decreased Type III cells more than a single dose, but loss of these cells may be due to factors related to the general health and/or cell renewal of taste buds rather than the life span of Type III cells. In general, pretreatment with amifostine appeared to protect taste cell renewal and the population of cells within taste buds from the cytotoxic effects of CYP with few observable adverse effects due to repeated administration. These findings may have important implications for patients undergoing chemotherapy.

MUTATION RESEARCH-GENETIC TOXICOLOGY AND ENVIRONMENTAL MUTAGENESIS 2019; 847:403032. [PMID: 31699349 DOI: 10.1016/j.mrgentox.2019.03.005] [Citation(s) in RCA: 17] [Impact Index Per Article: 3.4] [Reference Citation Analysis] [Abstract] [Track Full Text] [Subscribe] [Scholar Register] [Received: 11/23/2018] [Revised: 02/10/2019] [Accepted: 03/13/2019] [Indexed: 12/13/2022]
Abstract
Aneuploidy is regarded as a hallmark of cancer, however, its role is complex with both pro- and anti-carcinogenic effects evident. In this IWGT review, we consider the role of aneuploidy in cancer biology; cancer risk associated with constitutive aneuploidy; rodent carcinogenesis with known chemical aneugens; and chemotherapy-related malignant neoplasms. Aneuploidy is seen at various stages in carcinogenesis. However, the relationship between induced aneuploidy occurring after exposure and clonal aneuploidy present in tumours is not clear. Recent evidence indicates that the induction of chromosomal instability (CIN), may be more important than aneuploidy per se, in the carcinogenic process. Down Syndrome, trisomy 21, is associated with altered hematopoiesis in utero which, in combination with subsequent mutations, results in an increased risk for acute megakaryoblastic and lymphoblastic leukemias. In contrast, there is reduced cancer risk for most solid tumours in Down Syndrome. Mouse models with high levels of aneuploidy are also associated with increased cancer risk for particular tumours with long latencies, but paradoxically other types of tumour often show decreased incidence. The aneugens reviewed that induce cancer in humans and animals all possess other carcinogenic properties, such as mutagenicity, clastogenicity, cytotoxicity, organ toxicities, hormonal and epigenetic changes which likely account for, or interact with aneuploidy, to cause carcinogenesis. Although the role that aneuploidy plays in carcinogenesis has not been fully established, in many cases, it may not play a primary causative role. Tubulin-disrupting aneugens that do not possess other properties linked to carcinogenesis, were not carcinogenic in rodents. Similarly, in humans, for the tubulin-disrupting aneugens colchicine and albendazole, there is no reported association with increased cancer risk. There is a need for further mechanistic studies on agents that induce aneuploidy, particularly by mechanisms other than tubulin disruption and to determine the role of aneuploidy in pre-neoplastic events and in early and late stage neoplasia.

Abstract
Antineoplastic drugs (AD) have been increasingly used, but the disposal of their wastes in the environment via hospital effluent and domestic sewage has emerged as an environmental issue. The current risks posed to these animals and effects of pollutants on the reptiles' population level remain unknown due to lack of studies on the topic. The aim of the present study was to evaluate the mutagenicity of neonate Podocnemis expansa exposed to environmental concentrations (EC) of cyclophosphamide (Cyc). The adopted doses were EC-I 0.2 μg/L and EC-II 0.5 μg/L Cyc. These doses correspond to 1/10 and ¼ of concentrations previously identified in hospital effluents. Turtles exposed to the CyC recorded larger total number of erythrocyte nuclear abnormalities than the ones in the control group after 48-h exposure. The total number of abnormalities for both groups (EC-I and EC-II) 96 h after the experiment had started was statistically similar to that of animals exposed to high Cyc concentration (positive control 5 × 104 μg/L). This outcome confirms the mutagenic potential of Cyc, even at low concentrations. On the other hand, when the animals were taken to a pollutant-free environment, their mutagenic damages disappeared after 240 h. After such period, their total of abnormalities matched the basal levels recorded for the control group. Therefore, our study is the first evidence of AD mutagenicity in reptiles, even at EC and short-term exposure, as well as of turtles' recovery capability after the exposure to Cyc.

Abstract
The effect of Cereus jamacaru ethanolic extract in rats was analyzed using genotoxicity assays and liver ABCB1 and CYP2D4 gene expression. The lyophilized extract of C. jamacaru cladodes was analyzed with LC-MS/MS. Male Wistar rats (n=36) were equally distributed into six groups that did (+) or did not (-) receive cyclophosphamide treatments: Control (-); Control (+); EXP 1 (-), and EXP 1 (+), both treated with 210 mg/kg of ethanolic extract; and EXP 2 (-) and EXP 2 (+), both treated with 420 mg/kg of ethanolic extract. After 30 d of treatment, body weight and food and water intake were monitored. Right femur of the rats and spinal canal fluid were harvested and used for genotoxicity assays, and the liver samples were used for gene expression studies. The phytochemical analysis identified novel compounds. Animals treated with C. jamacaru showed lower body weight and food ingestion compared to controls (P<0.05). The genotoxicity assay showed an absence of ethanolic extract cytotoxicity. CYP2D4 expression was higher in EXP 2 groups compared with EXP 1 (-) group (P<0.05). ABCB1A expression was higher in negative groups compared with the positive groups. These results indicated a new phytochemical characterization of C. jamacaru and its effect on food ingestion and body weight gain. Moreover, the genotoxicity assay suggested that C. jamacaru ethanolic extract treatment presents significant intrinsic genotoxic potential and the enhanced expression of ABCB1 and CYP2D4 on C. jamacaru extract treatment suggests a role of the efflux transporter and microsomal enzyme, respectively, in C. jamacaru pharmacokinetics.

Abstract
Mesenchymal stem/stromal cells (MSCs) within the bone marrow (BM) are vitally important in forming the micro-environment supporting haematopoiesis after myeloablative chemotherapy. MSCs are known to be damaged phenotypically and functionally by chemotherapy; however, to the best our knowledge, the persistence of genotoxic effects of chemotherapy on the BM micro-environment has not been studied. We therefore aimed to evaluate genotoxic effects of chemotherapy on the BM both in vitro and in vivo, using the comet and micronucleus assays, focussing on the persistence of DNA lesions that may contribute to complications in the patient. The MSC cell line (HS-5) and primary cord blood mononuclear cells (CBMNCs: a source of undamaged DNA) were exposed to the chemotherapeutic agent cyclophosphamide (CY) within a physiologically relevant in vitro model. CY treatment resulted in significant increases in CBMNC DNA damage at all time points tested (3-48 h exposure). Similarly, HS-5 cells exposed to CY exhibited significant increases in DNA damage as measured by the comet assay, with increased numbers of abnormal cells visible in the micronucleus assay. In addition, even 48 h after removal of 48-h CY treatment, DNA damage remains significantly increased in treated cells relative to controls. In patients treated with chemotherapy for haematological malignancy, highly significant increases in damaged DNA were seen in BM cells isolated from one individual 1 year after completion of therapy for acute leukaemia compared with pretreatment (P < 0.001). Similarly, two individuals treated 7 and 17 years previously with chemotherapy exhibited significant increases of damaged DNA in MSC compared with untreated age- and sex-matched controls (P < 0.05). Unlike haematopoietic cells, MSCs are not replaced following a stem cell transplant. Therefore, long-term damage to MSC may impact on engraftment of either allogeneic or autologous transplants. In addition, persistence of DNA lesions may lead to genetic instability, correlating with the significant number of chemotherapy-treated individuals who have therapy-related malignancies.

Abstract
We investigated the relationship between metabolic activities of cytochrome P450 (CYP) isozymes present in microsomal fractions derived from the livers of 78 donors and micronucleus induction by cyclophosphamide (CPA). Consequently, a wide inter-individual variation in CYP activities was observed among the 78 donors. The CYP activities were partially correlated with the metabolic phenotypes predicted for the donors based on their single nucleotide polymorphisms. In addition, CPA induced micronucleus formation was seen for 47 out of 52 donors whose samples were tested with CPA doses ranging from 18.8 to 100 μg/mL. The CPA dose at which micronucleated cells were observed varied among the donors. Furthermore, a close correlation was identified between the catalytic activities of the CYP2B6, CYP2C9, CYP2C19, and CYP3A4 isozymes and micronucleus induction by CPA. To elucidate the mechanism underlying CPA-induced micronucleus formation in vitro tests were conducted on expression systems of CYP2B6, CYP2C9, CYP2C19, CYP2D6, and CYP3A4. Additionally, the metabolites of CPA generated by the expression systems were quantified by a liquid chromatography tandem mass spectrometer. Interestingly, several metabolites including the 4-hydroxyl form of CPA (4-OH-CPA) and phosphamide mustard were detected in the CYP2B6, CYP2C19, and CYP3A4 expression systems, but not in the CYP2C9 and CYP2D6 system. The presence of these metabolites was correlated with micronucleus induction by CPA. The absence of CPA metabolites in the CYP2C9 expression system might be associated with the lower 4-hydroxylase activity of this system. The present results suggest that inter-individual variability in the metabolic capacity of each donor was associated with potential micronucleus induction due to CPA. Additionally, CPA metabolites like 4-OH-CPA and phosphamide mustard produced by human CYP2B6, CYP2C9, CYP2C19, and CYP3A4 are suggested to be major determinants of micronucleus induction by CPA.

Abstract
This study is aimed at analysing biochemical and genetic endpoints of toxic effects after administration of adrenaline. For this purpose, the study was carried out on Wistar rats and three doses of adrenaline were used: 0.75 mg/kg, 1.5 mg/kg, and 3 mg/kg body weight. To achieve these aims, we investigated the effects of adrenaline on catalase (CAT), Cu, Zn-superoxide dismutase (SOD), malondialdehyde (MDA), nitrite (NO2−), carbonyl groups (PCC), and nitrotyrosine (3-NT). Total activity of lactate dehydrogenase (LDH), its relative distribution (LDH1–LDH5) activity, level of acute phase proteins (APPs), and genotoxic effect were also evaluated. The obtained results revealed that all doses of adrenaline induced a significant rise in CAT activity, MDA level, PCC, NO2−, and 3-NT and a significant decrease in SOD activity compared to control. Adrenaline exerted an increase in total activity of LDH, LDH1, and LDH2 isoenzymes. Further study showed that adrenaline significantly decreased serum albumin level and albumin-globulin ratio, while the level of APPs (α1-acid glycoprotein and haptoglobulin) is increased. The micronucleus test revealed a genotoxic effect of adrenaline at higher concentrations (1.5 mg/kg and 3 mg/kg body weight) compared to untreated rats. It can be concluded that adrenaline exerts oxidative and nitrative stress in rats, increased damage to lipids and proteins, and damage of cardiomyocytes and cytogenetic damage. Obtained results may contribute to better understanding of the toxicity of adrenaline with aims to preventing its harmful effects.

Abstract
In drug development, genetic toxicology studies are conducted using in vitro and in vivo assays to identify potential mutagenic and clastogenic effects, as outlined in the International Council for Harmonisation (ICH) S2 regulatory guideline. (Quantitative) structure-activity relationship ((Q)SAR) models that predict assay outcomes can be used as an early screen to prioritize pharmaceutical candidates, or later during product development to evaluate safety when experimental data are unavailable or inconclusive. In the current study, two commercial QSAR platforms were used to build models for in vitro chromosomal aberrations in Chinese hamster lung (CHL) and Chinese hamster ovary (CHO) cells. Cross-validated CHL model predictive performance showed sensitivity of 80 and 82%, and negative predictivity of 75 and 76% based on 875 training set compounds. For CHO, sensitivity of 61 and 67% and negative predictivity of 68 and 74% was achieved based on 817 training set compounds. The predictive performance of structural alerts in a commercial expert rule-based SAR software was also investigated and showed positive predictivity of 48-100% for selected alerts. Case studies examining incorrectly-predicted compounds, non-DNA-reactive clastogens, and recently-approved pharmaceuticals are presented, exploring how an investigational approach using similarity searching and expert knowledge can improve upon individual (Q)SAR predictions of the clastogenicity of drugs.

Fonseca TG, Auguste M, Ribeiro F, Cardoso C, Mestre NC, Abessa DMS, Bebianno MJ. Environmental relevant levels of the cytotoxic drug cyclophosphamide produce harmful effects in the polychaete Nereis diversicolor. THE SCIENCE OF THE TOTAL ENVIRONMENT 2018; 636:798-809. [PMID: 29727846 DOI: 10.1016/j.scitotenv.2018.04.318] [Citation(s) in RCA: 6] [Impact Index Per Article: 1.0] [Reference Citation Analysis] [Abstract] [Key Words] [MESH Headings] [Track Full Text] [Subscribe] [Scholar Register] [Received: 01/18/2018] [Revised: 04/23/2018] [Accepted: 04/24/2018] [Indexed: 06/08/2023]
Abstract
Cytotoxic drugs applied in chemotherapy enter the aquatic environment after patient's metabolism and excretion, in both main compounds and their respective metabolites. The increased consumption and discharge of these drugs raise concern on the genotoxic burden to non-target aquatic species, due to their unselective action on DNA. Settlement and adsorption of cytotoxic drugs to aquatic sediments pose risks to benthic species through chronic exposure. The aim of the present study was to assess the effects induced by the anticancer drug cyclophosphamide (CP) on the polychaete Nereis diversicolor, after 14 days of exposure to environmental relevant concentrations (10, 100, 500 and 1000 ng L-1). Burrowing impairment, neurotoxicity (Acetylcholinesterase - AChE activity), oxidative stress (superoxide dismutase - SOD; catalase - CAT; glutathione peroxidases - GPXs activities), biotransformation (glutathione-S-transferases - GST), oxidative damage (lipid peroxidation - LPO) and genotoxicity (DNA damage) were assessed. Burrowing impairments were higher at the lowest CP concentrations tested. The higher CP levels tested (500 and 1000 ng L-1) induced a significant inhibition on the enzymatic antioxidant system (SOD, GPx) and on GST activity. DNA damage was also significant at these concentrations as an outcome of CP metabolism, and high levels of oxidative damage occurred. The results showed that the prodrug CP was metabolically activated in the benthic biological model N. diversicolor. In addition to the potential cytotoxic impact likely to be caused in aquatic species with similar metabolism, N. diversicolor proved to be reliable and vulnerable to the cytotoxic mode of action of CP, even at the lower doses.

Abstract
Aims and Background The aim of the present study was to evaluate the individual sensitivity of cancer patients to different antineoplastic drugs administered in standard protocols by assessing their acute cytogenetic effects on peripheral blood lymphocytes. Methods and Study Design In 12 patients undergoing cancer chemotherapy, acute cytogenetic effects on peripheral blood lymphocytes were evaluated by analysis of structural chromosome aberrations and micronuclei. All patients were given antineoplastic drugs, mainly as polychemotherapy. The frequencies of both cytogenetic biomarkers determined after the first chemotherapy cycle were compared with their pre-treatment (baseline) values. Results All chemotherapy protocols employed induced clear cytogenetic effects in both tests studied. The results obtained indicate interindividual variations between cytogenetic damage in peripheral blood lymphocytes among cancer patients. Statistically significant increases in the total number of structural chromosome aberrations and micronuclei in lymphocytes analyzed after chemotherapy compared to pre-therapy samples were observed in almost all patients studied. The highest level of chromosome damage as well as the highest incidence of micronuclei was observed following administration of the ACOP protocol (adriamycin, cyclophosphamide and vincristine). The proportions of signal-positive and signal-negative micronuclei were evaluated using DAPI staining, while silver staining revealed Ag-NOR+ and Ag-NOR− micronuclei. In some patients the incidence of signal-positive and Ag-NOR+ micronuclei after treatment was increased, indicating a more pronounced susceptibility of particular chromosomes to damage caused by antineoplastic drugs. Conclusions With regard to the results obtained we may conclude that both parameters used in the present study on peripheral lymphocytes are sensitive biomarkers and can be successfully employed for biomonitoring of acute cytogenetic effects induced by antineoplastic drugs in standard clinical protocols for cancer treatment.

BMC Cancer 2018; 18:87.

Abstract
BACKGROUND Patients with highly mutated tumors, such as melanoma or smoking-related lung cancer, have higher rates of response to immune checkpoint blockade therapy, perhaps due to increased neoantigen expression. Many chemotherapies including platinum compounds are known to be mutagenic, but the impact of standard treatment protocols on mutational burden and resulting neoantigen expression in most human cancers is unknown. METHODS We sought to quantify the effect of chemotherapy treatment on computationally predicted neoantigen expression for high grade serous ovarian carcinoma patients enrolled in the Australian Ovarian Cancer Study. In this series, 35 of 114 samples were collected after exposure to chemotherapy; 14 are matched with an untreated sample from the same patient. Our approach integrates whole genome and RNA sequencing of bulk tumor samples with class I MHC binding prediction and mutational signatures extracted from studies of chemotherapy-exposed Caenorhabditis elegans and Gallus gallus cells. We additionally investigated the relationship between neoantigens, tumor infiltrating immune cells estimated from RNA-seq with CIBERSORT, and patient survival. RESULTS Greater neoantigen burden and CD8+ T cell infiltration in primary, pre-treatment samples were independently associated with improved survival. Relapse samples collected after chemotherapy harbored a median of 78% more expressed neoantigens than untreated primary samples, a figure that combines the effects of chemotherapy and other processes operative during relapse. The contribution from chemotherapy-associated signatures was small, accounting for a mean of 5% (range 0-16) of the expressed neoantigen burden in relapse samples. In both treated and untreated samples, most neoantigens were attributed to COSMIC Signature (3), associated with BRCA disruption, Signature (1), associated with a slow mutagenic process active in healthy tissue, and Signature (8), of unknown etiology. CONCLUSION Relapsed ovarian cancers harbor more predicted neoantigens than primary tumors, but the increase is due to pre-existing mutational processes, not mutagenesis from chemotherapy.

Abstract
Anticancer drugs enter aquatic environment predominantly via hospital and municipal wastewater effluents where they may, due to their genotoxic potential, cause adverse environmental effects even at very low doses. In this study we evaluated cytotoxic and genotoxic potential of two widely used anticancer drugs, cyclophosphamide (CP) and ifosfamide (IF) as individual compounds and in a complex mixture together with 5-fluorouracil (5-FU) and cisplatin (CDDP) because these four drugs have been frequently detected in an oncological ward effluents. As an experimental model we used zebrafish liver cell (ZFL) line. The cytotoxicity was determined with the MTS assay and genotoxicity with the comet assay and cytokinesis block micronucleus (CBMN) assay that measure the formation of DNA strand breaks and genomic instability, respectively. CP and IF exerted low cytotoxicity towards ZFL cells. Both compounds induced DNA strand breaks and genomic instability, however at relatively high concentrations that are not relevant for the contamination of aquatic environment. The mixture of CP, IF, 5-FU and CDDP was tested at maximal detected concentrations of each drug as determined in the effluents from the oncological ward. The mixture was not cytotoxic and did not induce genomic instability, but it induced significant increase in the formation of DNA strand breaks at concentrations of individual compounds that were several orders of magnitude lower from those that were effective when tested as individual compounds. The results indicate that such mixtures of anticancer drugs may pose a threat to aquatic organisms at environmentally relevant concentrations and contribute to the accumulating evidence that it is not always possible to predict adverse effects of complex mixtures based on the toxicological data for individual compounds.

Abstract
Effects of Lepidium meyenii (Maca) on cyclophosphamide (CYP)-induced gonadal toxicity in male mice were investigated. Mice were assigned to six treatment groups: Vehicle control, CYP control, CYP plus oral Maca (500 or 1,000 mg/kg), and oral Maca (500 or 1,000 mg/kg). CYP was administered via the intraperitoneal route (days 1-2), while vehicle or Maca were administered daily for 28 days. On day 28, half of the animals in each group were either sacrificed or paired with age-matched females for fertility assessment. Plasma testosterone assay, sperm analysis and assessment of tissue antioxidant/morphological status were also carried out. CYP administration was associated with oxidative stress, subfertility and morphometric/morphological indices of gonadal injury, while administration of Maca mitigated CYP-induced gonadal toxicity and subfertility. This study shows that Maca is beneficial in the mitigation of CYP-induced male gonadal insufficiency and/or testicular morphological changes; however, further studies will be needed to ascertain its usability for this purpose in humans.

Abstract
Cyclophosphamide is a drug used for chemotherapy and as an immune-suppressive in the organ transplantation. Despite its many clinical implications in the treatment of cancers, this drug has toxic effects on the reproductive system. This study aimed to evaluate the effect of ghrelin against the damages caused by cyclophosphamide. In this experimental study, 40 male mice were randomly divided into four groups: (i) control; (ii) cyclophosphamide; (iii) cyclophosphamide + ghrelin; and (iv) ghrelin. Cyclophosphamide (100 mg/kg body weight), once a week, and ghrelin (80 μg/kg body weight), daily, were administered intraperitoneally for 5 weeks. After 5 weeks, the epididymides were removed and the lipid peroxidation, total antioxidant capacity and sperm parameters were examined. The fertility rate was evaluated by performance in vitro fertilisation. In the mice exposed to cyclophosphamide, the number of spermatozoa and viability, as well as total antioxidant capacity, decreased significantly (p < .05). The increase in the abnormal sperm and MDA levels was observed (p < .05). In addition, the fertility rate decreased in this group, while the use of ghrelin significantly improved the above disorders in the treatment group (p < .05). The findings of this study showed that ghrelin attenuates negative effects caused by cyclophosphamide in the sperm parameters and enhances the fertility.

Abstract
BACKGROUND We investigated whether GSTT1 ("null" allele), GSTM1 ("null"allele), GSTP1 (A313G), RFC1 (G80A), MTHFR (C677T), TS (2R/3R) polymorphisms were associated with toxicity and survival in patients with early breast cancer (EBC) treated with adjuvant chemotherapy (CT). METHODS This prospective trial included patients with stage I-III BC subjected to CT with CMF or FEC regimens. PCR-RFLP was performed for MTHFR, RFC1 and GSTP1, while PCR for TS, GSTT1 and GSTM1 genes. RESULTS Among the 244 patients consecutively enrolled, 48.7% were treated with FEC and 51.3% with CMF. Patients with TS2R/3R genotype showed less frequently severe neutropenia (G3/G4) than those with TS2R/2R and 3R/3R genotype (p = 0.038). Patients with MTHFRCT genotype had a higher probability of developing severe neutropenia than those with MTHFR CC genotype (p = 0.043). Patients with RFC1GG or GSTT1-null genotype or their combination (GSTT1-null/RFC1GG) were significantly associated with a shorter disease free survival (DFS) (p = 0.009, p = 0.053, p = 0.003, respectively) and overall survival (OS) (p = 0.036, p = 0.015, p = 0.005, respectively). Multivariate analysis confirmed the association of RFC1GG genotype with a shorter DFS (p = 0.018) and of GSTT1-null genotype of a worse OS (p = 0.003), as well as for the combined genotypes GSTT1-null/RFC1GG, (DFS: p = 0.004 and OS: p = 0.003). CONCLUSIONS Our data suggest that TS2R/2R and 3R/3R or MTHFR CT genotypes have a potential role in identifying patients with greater risk of toxicity to CMF/FEC and that RFC1 GG and GSTT1-null genotypes alone or in combination could be important markers in predicting clinical outcome in EBC patients.

Abstract
Pendimethalin (PND) is one of the common herbicides used worldwide. Fresh water fish, Channa punctatus, was exposed to PND in aquaria wherein its LC50 value was recorded to be 3.6 mg/L. Three sublethal (SL) concentrations, namely, 0.9, 1.8, and 2.7 mg/L were selected for the evaluation of genotoxicity and oxidative stress generated in the fish. In vivo comet assay was carried out in the blood, liver, and gill cells after exposing the fish to aforesaid SL concentrations of PND for 24, 48, 72, and 96 h. The results of the comet assay demonstrated the genotoxicity of PND in all the three tissues. Induction of oxidative stress in the gill cells was affirmed by the increased lipid peroxidation (LPO) and decreased levels of reduced glutathione, superoxide dismutase, and catalase. Frequencies of erythrocytic nuclear abnormalities (ENA) and micronuclei (MN) were also used to assess the genotoxic potential of PND on C. punctatus. MN frequency did not show any enhancement after PND exposure, but the frequency of ENA such as kidney-shaped nuclei, segmented nuclei and lobed nuclei, showed a significant increase after 24-96 h. Thus, ENA seems to be a better biomarker than MN for PND induced genotoxicity. © 2015 Wiley Periodicals, Inc. Environ Toxicol 31: 1520-1529, 2016.

The aim of this study was to evaluate the genotoxicity of the herbicide diuron in the wing-spot test and a novel wing imaginal disk comet assay in Drosophila melanogaster. The wing-spot test was performed with standard (ST) and high-bioactivation (HB) crosses after providing chronic 48 h treatment to third instar larvae. A positive dose-response effect was observed in both crosses, but statistically reduced spot frequencies were registered for the HB cross compared with the ST. This latter finding suggests that metabolism differences play an important role in the genotoxic effect of diuron. To verify diuron's ability to produce DNA damage, a wing imaginal disk comet assay was performed after providing 24 h diuron treatment to ST and HB third instar larvae. DNA damage induced by the herbicide had a significantly positive dose-response effect even at very low concentrations in both strains. However, as noted for the wing-spot test, a significant difference between strains was not observed that could be related to the duration of exposure between both assays. A positive correlation between the comet assay and the wing-spot test was found with regard to diuron genotoxicity.

Abstract
Reproductive toxicity is one of the side effects of cyclophosphamide (CP) in cancer treatment. Pumpkin seeds and Zingiber officinale are natural sources of antioxidants. We investigated the possible protective effect of combined pumpkin seed and Zingiber officinale extracts on sperm characteristics, epididymal histology and biochemical parameters of CP-treated rats. Male adult Wistar rats were divided randomly into six groups. Group 1, as a control, received an isotonic saline solution injection intraperitoneally (IP). Group 2 were injected IP with a single dose of CP (100 mg/kg) once. Groups 3 and 4 received CP plus 300 and 600 mg/kg combined pumpkin seed and Zingiber officinale extract (50:50). Groups 5 and 6 received only 300 and 600 mg/kg combined pumpkin seed and Zingiber officinale extract. Six weeks after treatment, sperm characteristics, histopathological changes and biochemical parameters were assessed. In CP-treated rats, motile spermatozoa were decreased, and abnormal or dead spermatozoa increased significantly (P < 0.001) but administration of the mixed extract improved sperm parameters. Epididymal epithelium and fibromascular thickness were also improved in extract-treated rats compared to control or CP groups. Biochemical analysis showed that the administration of combined extracts could increase the total antioxidant capacity (TAC) level significantly in groups 3, 4, 5 and 6. Interestingly, the mixed extract could decrease most of the side effects of CP such as vacuolization and separation of epididymal tissue. Our findings indicated that the combined extracts might be used as a protective agent against CP-induced reproductive toxicity.

Abstract
The development of a tool that can provide early-stage predictive toxicology data may accelerate the identification of safer drug candidates, and thereby improve the clinical progression of drug candidates to pharmaceuticals. Such a system would require an accurate and reliable technique that is amenable to the large number of drug candidates that must be screened in the lead discovery and optimization stages of drug development. A key component of predictive toxicology is the ability to harness the metabolite-generating capacity of human cytochromes P450, which are involved in first-pass drug metabolism function of the liver. We have miniaturized P450 catalysis into a microarray format consisting of up to 11,200 isolated P450 reactions, each in 5 nL sol-gel spots, on a single functionalized glass microscope-size biochip. This dramatic scale down from more conventional 96 and 384-well plate scales (at least a 1000-fold reduction in volume) did not adversely affect P450 catalytic activity. Based on the functionality of the P450-containing microarray, we developed the metabolizing enzyme toxicology assay Chip (MetaChip), which combines high-throughput P450 catalysis with cell-based screening on a microscale platform. Proof of concept was demonstrated using anticancer prodrugs cyclophosphamide and Tegafur, as well as the analgesic acetaminophen. The MetaChip may provide a high-throughput microscale alternative to currently used in vitro methods for human metabolism and toxicology screening.

Abstract
Increased survival of children with juvenile systemic lupus erythematosus (jSLE) and improved prognosis have led to a change in the long-term health issues arising for jSLE patients. Preservation of gonadal functioning and fertility are of increasing importance for young adults with jSLE. Events during childhood, such as exposure to alkylating agents, may compromise the reproductive potential. Even in the absence of gonadotoxic therapies, fertility may be decreased through organs specific involvement with jSLE. Strategies to preserve the reproductive potential of girl and boys with jSLE are discussed. Lupus (2007) 16, 593—599.
