Ameliorative Effect of Chitosan/ Spirulina platensis Ethanolic Extract Nanoformulation against Cyclophosphamide-Induced Ovarian Toxicity: Role of PPAR-γ/Nrf-2/HO-1 and NF-kB/TNF-α Signaling Pathways. Mar Drugs 2024; 22:395. [PMID: 39330276 PMCID: PMC11433581 DOI: 10.3390/md22090395] [Citation(s) in RCA: 0] [Impact Index Per Article: 0] [Reference Citation Analysis] [Abstract] [Key Words] [MESH Headings] [Track Full Text] [Journal Information] [Subscribe] [Scholar Register] [Received: 06/10/2024] [Revised: 08/14/2024] [Accepted: 08/27/2024] [Indexed: 09/28/2024] Open
Abstract
Cyclophosphamide (CP) is an anticancer drug that causes infertility disorders. This study was designed to evaluate a nanoformulation of chitosan with an ethanolic extract from Spirulina platensis in terms of its protection against cyclophosphamide-induced ovarian toxicity. Nine groups of female Wistar rats were randomly assigned as follows: 1: control vehicle, 2: chitosan polymer, 3: telmisartan, 4: Spirulina platensis extract, 5: nanoformulation of the Spirulina platensis, and 6: single injection of CP; groups 7, 8, and 9 received the same treatments as those used in groups 3, 4, and 5, respectively, with a single dose of CP (200 mg/kg, I.P). The results displayed that the CP treatment decreased estradiol, progesterone, anti-mullerian hormone, and GSH content, and it downregulated PPAR-γ, Nrf-2, and HO-1 gene expression. In addition, the CP treatment caused an increase in the FSH, LH, and MDA levels. In the same manner, the protein expression of caspase-3, NF-kB, and TNF-α was upregulated in response to the CP treatment, while PPAR-γ was downregulated in comparison with the control. The rats treated with SPNPs exhibited a substantial reduction in the detrimental effects of oxidative stress and inflammation of the ovarian tissue. This study's conclusions showed that SPNPs counteracted the effects of CP, preventing the death of ovarian follicles and restoring the gonadotropin hormone balance and normal ovarian histological appearance.

Abstract
Cyclophosphamide, an oxazaphosphorine prodrug is frequently used in treatment of neuroblastoma, which is one of the most prevalent solid organ malignancies in infants and young children. Cytochrome P450 2B6 (CYP2B6) is the major catalyst and CYP2C19 is the minor enzyme in bioactivation and inactivation pathways of cyclophosphamide. CYP-mediated metabolism may contribute to the variable pharmacokinetics of cyclophosphamide and its toxic byproducts leading to insufficient response to the therapy and development of clinically significant side effects. The aim of the study was to reveal the contribution of pharmacogenetic variability in CYP2B6 and CYP2C19 to the treatment efficacy and cyclophosphamide-induced side effects in pediatric neuroblastoma patients under cyclophosphamide therapy (N = 50). Cyclophosphamide-induced hematologic toxicities were pivotal in all patients, whereas only moderate hepatorenal toxicity was developed. The patients' CYP2B6 metabolizer phenotypes were associated with the occurrence of lymphopenia, thrombocytopenia, and monocytopenia as well as of liver injury, but not with kidney or urinary bladder (hemorrhagic cystitis) toxicities. Furthermore, the patients' age (< 1.5 years, P = 0.03) and female gender (P ≤ 0.02), but not CYP2B6 or CYP2C19 metabolizer phenotypes appeared as significant prognostic factors in treatment outcomes. Our results may contribute to a better understanding of the impact of CYP2B6 variability on cyclophosphamide-induced side effects.

Abstract
PURPOSE Cyclophosphamide is an alkylating agent with nephrotoxicity that constrains its clinical application. Berberine is an isoquinoline derivative alkaloid with biological functions like antioxidant and anti-inflammatory. The current research intended to examine the nephroprotective impacts of berberine against cyclophosphamide-stimulated nephrotoxicity. METHODS Forty animal subjects were randomly separated into five categories of control (Group I), cyclophosphamide (200 mg/kg, i.p., on 7th day) (Group II), and groups III and IV that received berberine 50 and 100 mg/kg orally for seven days and a single injection of cyclophosphamide on 7th day. Group V as berberine (100 mg/kg, alone). On day 8, blood samples were drawn from the retro-orbital sinus to determine serum levels of blood urea nitrogen (BUN), creatinine (Cr), neutrophil gelatinase-associated lipocalin (NGAL), and kidney injury molecule-1 (KIM-1) as biomarkers for kidney injury. Nitric oxide (NO), malondialdehyde (MDA) and glutathione (GSH) levels, catalase (CAT), superoxide dismutase (SOD), glutathione peroxidase (GPx) activities as oxidative stress factors, tumor necrosis factor-α (TNF-α) and interleukin 1 beta (IL-1β) levels as inflammatory mediators were assessed in kidney tissue. RESULTS The results of this study demonstrated that berberine was able to protect remarkably the kidney from CP-induced injury through decreasing the level of BUN, Cr, NGAL, KIM-1, NO, MDA TNF-α, IL-1β and increasing the level of GSH, CAT, SOD, and GPx activities. CONCLUSION Berberine may be employed as a natural agent to prevent cyclophosphamide-induced nephrotoxicity through anti-oxidant and anti-inflammatory effects.

Abstract
Hemorrhagic cystitis is a potentially deadly complication associated with radiation therapy and chemotherapy. This study explored the protective effect of edaravone (ED) on cyclophosphamide (CP)-induced hemorrhagic cystitis, oxidative stress, and inflammation in rats. The animals received 20 mg/kg ED for 10 days and a single injection of 200 mg/kg CP on day 7. CP induced tissue injury manifested by the diffuse necrotic changes, disorganization of lining mucosa, focal hemorrhagic patches, mucosal/submucosal inflammatory cells infiltrates, and edema. CP increased malondialdehyde (MDA), nitric oxide (NO), tumor necrosis factor-alpha, and interleukin 6 (IL-6), decreased IL-10, and upregulated toll-like receptor 4 (TLR-4), nuclear factor-kappa B (NF-κB) p65, Janus kinase 1 (JAK1), and signal transducer and activator of transcription 3 (STAT3) in the urinary bladder of rats. ED effectively prevented the histopathological alterations, decreased MDA, NO, and inflammatory mediators, and downregulated TLR-4, NF-κB, JAK1, and STAT3 in CP-induced rats. Treatment with ED upregulated ikβ kinase β, IL-10, nuclear factor-erythroid 2 related factor 2 (Nrf2), and cytoglobin, and boosted glutathione, superoxide dismutase, and glutathione S-transferase. Molecular docking simulations revealed the ability of ED to bind TLR-4, NF-κB, JAK1, and STAT3. In vitro, ED increased the cytotoxic activity of CP against HeLa, Caco-2, and K562 cell lines. In conclusion, ED prevented CP-induced hemorrhagic cystitis in rats by attenuating oxidative stress, suppressing TLR-4/NF-κB, and JAK1/STAT3 signaling and boosted Nrf2, cytoglobin, and antioxidants.

J Food Biochem 2021; 45:e13854. [PMID: 34245022 DOI: 10.1111/jfbc.13854] [Citation(s) in RCA: 0] [Impact Index Per Article: 0] [Reference Citation Analysis] [Abstract] [Key Words] [Grants] [Track Full Text] [Journal Information] [Subscribe] [Scholar Register] [Received: 04/12/2021] [Revised: 06/14/2021] [Accepted: 06/23/2021] [Indexed: 12/01/2022]
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
Cyclophosphamide is anticancer drug with a well-Known nephrotoxicity. This work was applied to study the lucrative antioxidant influence of metformin as co-therapy on the nephrotoxicity induced by cyclophosphamide in the treatment of different cancer diseases. Four groups of male Sprague Dawley rats were used; Control group (C) received single I.P. injection of 0.2 ml saline, Metformin (MET) group received daily gavage of 200 mg/kg metformin for two weeks, Cyclophosphamide (CP) group received single I.P. injection of 200 mg/kg CP, Protector group (CP.MET) received daily gavage of 200 mg/kg metformin for two weeks and single I.P. injection of 200 mg/kg CP at day 7. By day 14 rats were euthanized. Samples were collected from kidney tissues and blood for kidney function evaluation, histopathological and assessment of oxidative stress markers. The results disclosed that CP yields many functional and structural damage to the kidney, worsened oxidative stress markers and kidney function indicators. The protector group displayed better kidney tissue morphology, acceptable kidney function indicators as well as satisfactory oxidative stress markers. In assumption, metformin could be combined with CP owing to its lucrative effect counter to CP persuaded nephrotoxicity.

Abstract
Cyclophosphamide (CP) is a chemotherapeutic agent which is extensively used in the treatment of multiple neoplastic and nonneoplastic diseases like breast cancer, lymphomas, systemic lupus erythematosus, and multiple sclerosis. Dose-limiting side effects, mainly nephrotoxicity is a major problem hindering its use in the clinical practice. CP induces nephrogenic syndrome of inappropriate antidiuresis mostly via the activation of arginine vasopressin V2 receptors. Moreover, CP produces reactive metabolites which is responsible for augmentation of lipid peroxidation and oxidative stress. Tolvaptan (TOL) is a selective vasopressin V2 receptor antagonist used in the treatment of clinically significant hyponatremia, volume overload in heart failure, and liver cirrhosis with edema. The present study aimed to investigate the potential protective effect of TOL in CP-induced nephrotoxicity. Twenty-four adult male albino rats were randomly divided into four groups: the control group, TOL group that treated daily with tolvaptan (10 mg/kg/d, orally), CP group where CP was administered intraperitoneally 75 mg/kg on days 3, 4, 5, 19, 20, and 21 of study, and the CP + TOL group where animals were treated with TOL daily with (10 mg/kg/d, orally) for 22 days with concomitant administration of CP as described before. Coadministration of TOL with CP induces significant improvement in the level of urine volume, serum Na+, serum osmolarity, urinary creatinine, and free water clearance in addition to significant reduction of body weight, serum creatinine, urea, serum K+, blood pressure, urine osmolarity, and the fractional excretion of sodium as compared to CP-treated group. In addition, coadministration of TOL significantly reduced MDA, the marker of lipid peroxidation, and different pro-inflammatory cytokines. Histopathological changes showed improvement in the signs of nephrotoxicity with the coadministration of TOL. Also, co-treatment with TOL significantly decreased the level of markers of apoptosis as caspase-3 and Bax with increased expression of antiapoptotic Bcl-2 in renal tissue as compared to CP-treated group.

Abstract
The clinical use of cyclophosphamide and ifosfamide is limited by a resultant bladder toxicity which has been attributed to the metabolite acrolein. Another metabolite chloroacetaldehyde (CAA) associated with nephrotoxicity, has not been investigated for toxicity in the bladder and this study investigates the effects of acrolein and CAA on human urothelial cells in vitro. Human urothelial cells (RT4 and T24) were treated with acrolein or CAA and changes in cell viability, reactive oxygen species, caspase-3 activity and release of urothelial mediators ATP, acetylcholine, PGE2 were measured. The protective effects of N-acetyl cysteine (NAC) were also assessed. Both metabolites were toxic to human urothelial cells, however, CAA significantly decreased cell viability at a ten-fold lower concentration (10 µM) than acrolein (100 µM). This was associated with increased ROS production and caspase-3 activity. NAC protected cells from these changes. In RT4 cells 100 µM acrolein caused a significant increase in basal and stretch-induced ATP, Ach and PGE2 release. In T24 cells chloroacetaldehyde (10 µM) increased basal and stimulated ATP and PGE2 levels. Again, NAC protected against changes in urothelial mediator release following acrolein or CAA. This study is the first to report that CAA in addition to acrolein contributes to the urotoxicity of cyclophosphamide and ifosfamide. Both metabolites altered urothelial mediator levels which could contribute to the sensory and functional bladder changes experienced by patients after treatment with cyclophosphamide or ifosfamide. Alterations in urothelial cell viability and mediator release may be causally linked to oxidative stress, with NAC providing protection against these changes.

Abstract
In this study, we aimed to evaluate whether the encapsulation of ellagic acid (EA) into nanoliposomes would improve its potential in preventing cyclophosphamide-induced liver damage. Stability and antioxidative potential of free and encapsulated EA were determined. Experimental study conducted in vivo included ten groups of rats treated with cyclophosphamide and ellagic acid in its free and encapsulated form during 5 days. The protective effect of EA in its free and encapsulated form was determined based on serum liver function, liver tissue antioxidative capacities, and oxidative tissue damage parameters. Also, tissue morphological changes following cyclophosphamide administration were studied using standard histopathological and immunohistochemical analyses. The encapsulation of EA significantly prevented its degradation and improved its antioxidant properties in in vitro conditions. In in vivo experiments in both forms of EA were found to prevent rat liver damage induced by cyclophosphamide estimated through the changes in serum liver-damage parameters and tissue antioxidant capacities, as well as based on oxidatively modified lipids and proteins. Also, changes in morphology of liver cells and the expressions of Bcl-2, HIF-1α, and CD15 molecules in livers of animals of different experimental groups are in accordance with the obtained biochemical parameters. Thus, the encapsulation process might be effective in preventing EA from different environmental influences and could significantly increase its hepatoprotective potential. The encapsulation could prevent ellagic acid degradation and might deliver this potent compound to its target tissue in significantly larger quantities than when it is administered in its free form.

IPSE, a urogenital parasite-derived immunomodulatory protein, ameliorates ifosfamide-induced hemorrhagic cystitis through downregulation of pro-inflammatory pathways. Sci Rep 2019; 9:1586.

Abstract
Ifosfamide and other oxazaphosphorines can result in hemorrhagic cystitis, a constellation of complications caused by acrolein metabolites. We previously showed that a single dose of IPSE (Interleukin-4-inducing principle from Schistosoma eggs), a schistosome-derived host modulatory protein, can ameliorate ifosfamide-related cystitis; however, the mechanisms underlying this urotoxicity and its prevention are not fully understood. To provide insights into IPSE’s protective mechanism, we undertook transcriptional profiling of bladders from ifosfamide-treated mice, with or without pretreatment with IPSE or IPSE-NLS (a mutant of IPSE lacking nuclear localization sequence). Ifosfamide treatment upregulated a range of proinflammatory genes. The IL-1β-TNFα-IL-6 proinflammatory cascade via NFκB and STAT3 pathways was identified as the key driver of inflammation. The NRF2-mediated oxidative stress response pathway, which regulates heme homoeostasis and expression of antioxidant enzymes, was highly activated. Anti-inflammatory cascades, namely Wnt, Hedgehog and PPAR pathways, were downregulated. IPSE drove significant downregulation of major proinflammatory pathways including the IL-1β-TNFα-IL-6 pathways, interferon signaling, and reduction in oxidative stress. IPSE-NLS reduced inflammation but not oxidative stress. Taken together, we have identified signatures of acute-phase inflammation and oxidative stress in ifosfamide-injured bladder, which are reversed by pretreatment with IPSE. This work revealed several pathways that could be therapeutically targeted to prevent ifosfamide-induced hemorrhagic cystitis.

Abstract
Drug shortages in tertiary care hospitals always limit the health system's ability to provide quality care to the patients. Immediately following the existing shortage of 5 different oncology drugs in Pakistan, numerous patients are finding themselves in a desperate state of no cure for their illness. Cardinal factors responsible for this unfortunate situation include interruption in vendor supplies and regulatory authorities' issues related to approval and pricing. Effective review of policies by regulatory authorities for availability of drugs will certainly avoid this miserable condition in the future and ensure continuation of high-quality care to patients by health care systems.

Abstract
Chemotherapy-induced hemorrhagic cystitis (CHC) can be difficult to manage. Prior work suggests that IL-4 alleviates ifosfamide-induced hemorrhagic cystitis (IHC), but systemically administered IL-4 causes significant side effects. We hypothesized that the Schistosoma hematobium homolog of IL-4-inducing principle from Schistosoma mansoni eggs (H-IPSE), would reduce IHC and associated bladder pathology. IPSE binds IgE on basophils and mast cells, triggering IL-4 secretion by these cells. IPSE is also an “infiltrin,” translocating into the host nucleus to modulate gene transcription. Mice were administered IL-4, H-IPSE protein or its nuclear localization sequence (NLS) mutant, with or without neutralizing anti-IL-4 antibody, or 2-mercaptoethane sulfonate sodium (MESNA; a drug used to prevent IHC), followed by ifosfamide. Bladder tissue damage and hemoglobin content were measured. Spontaneous and evoked pain, urinary frequency, and bladdergene expression analysis were assessed. Pain behaviors were interpreted in a blinded fashion. One dose of H-IPSE was superior to MESNA and IL-4 in suppressing bladder hemorrhage in an IL-4-dependent fashion and comparable with MESNA in dampening ifosfamide-triggered pain behaviors in an NLS-dependent manner. H-IPSE also accelerated urothelial repair following IHC. Our work represents the first therapeutic exploitation of a uropathogen-derived host modulatory molecule in a clinically relevant bladder disease model and indicates that IPSE may be an alternative to MESNA for mitigating CHC.—Mbanefo, E.

Abstract
In folklore medicine, the plant Emilia sonchifolia, belonging to the family Asteraceae, is used for treating tumour and inflammation. In our previous studies, we have done a thorough phytochemical investigation of E. sonchifolia with a report on its potent antimetastatic activity. Further, we isolated and characterised its active fraction (AFES) containing the major compound γ-humulene with an evaluation of the antiangiogenic effect of AFES (5 mg/kg b.wt.). In the first part of the present study, AFES in different concentrations was used for the assessment of its possible anti-inflammatory effect employing three in vivo inflammatory models. Further using the most effective concentration of AFES 5 mg/kg b.wt, its effect on proinflammatory cytokine levels was recorded along with a confirmatory gene expression analysis. The results manifested with a reduction in the paw oedema significantly decreased levels of proinflammatory cytokines, C-reactive protein, nitric oxide and also there was an efficient downregulation of cyclooxygenase-2 and inducible nitric oxide. Urotoxicity is one of the major side effects of conventional chemotherapy. So in the second part of the study, we used AFES in combination with the conventional therapeutic agent cyclophosphamide in vivo in mice. The effect of AFES on urotoxicity was assessed from various biochemical parameters, cytokine markers and finally with a histopathology of the bladder. The current study revealed the protective effects of AFES, implicating reduced levels of urea nitrogen, by revamping of glutathione and marker cytokine levels towards positive amelioration. The results obtained altogether proved the safeguarding effect of AFES in murine experimental models.

Abstract
Gamma-glutamylcysteine ethyl ester (GCEE) is a precursor of glutathione (GSH) with promising hepatoprotective effects. This investigation aimed to evaluate the hepatoprotective effects of GCEE against cyclophosphamide- (CP-) induced toxicity, pointing to the possible role of peroxisome proliferator activated receptor gamma (PPARγ). Wistar rats were given GCEE two weeks prior to CP. Five days after CP administration, animals were sacrificed and samples were collected. Pretreatment with GCEE significantly alleviated CP-induced liver injury by reducing serum aminotransferases, increasing albumin, and preventing histopathological and hematological alterations. GCEE suppressed lipid peroxidation and nitric oxide production and restored GSH and enzymatic antioxidants in the liver, which were associated with downregulation of COX-2, iNOS, and NF-κB. In addition, CP administration significantly increased serum proinflammatory cytokines and the expression of liver caspase-3 and BAX, an effect that was reversed by GCEE. CP-induced rats showed significant downregulation of PPARγ which was markedly upregulated by GCEE treatment. These data demonstrated that pretreatment with GCEE protected against CP-induced hepatotoxicity, possibly by activating PPARγ, preventing GSH depletion, and attenuating oxidative stress, inflammation, and apoptosis. Our findings point to the role of PPARγ and suggest that GCEE might be a promising agent for the prevention of CP-induced liver injury.

Abstract
Objective Haemorrhagic cystitis (HC) is a relatively common complication of chemotherapy and radiotherapy to the pelvic area, but can be a challenging condition to treat, particularly since there is currently a lack of UK-led guidelines available on how it should optimally be defined and managed. Materials and methods A comprehensive literature search was undertaken to evaluate the evidence for the diagnosis, prevention and management of cancer treatment-induced HC. Results Recommendations and a proposed management algorithm for the diagnosis, prevention and treatment of HC, as well as the management of intractable haematuria, have been developed based on the expert opinion of the multidisciplinary consensus panel following a comprehensive review of the available clinical data. Conclusion These guidelines are relevant and applicable to current clinical practice and will help clinicians optimally define and manage this potentially serious condition.

Abstract
Background: Gallic acid (GA) is an endogenous plant phenol known to have antioxidant, free radical scavenging ability, anti-inflammatory, anti-cancer, and anti-fungal properties. The aim of this study was to assess the protective effect of GA on cyclophosphamide (CPA)-induced hepatotoxicity in male Wistar rats. Methods: Sixty rats were grouped into six groups of 10 rats per group. Group 1 received distilled water. Group 2 received CPA at 200 mg/kg single dose intraperitoneally on day 1. Groups 3 and 4 received a single dose of CPA (200 mg/kg) intraperitoneally on day 1 and then were treated with GA at 60 and 120 mg/kg body weight for 14 days, respectively. Rats in Groups 5 and 6 only received GA at 60 and 120 mg/kg body weight for 14 days, respectively. GA was administered orally. Results: CPA induced hepatic damage as indicated by significant elevation (P < 0.05) in aspartate aminotransferase, organ weight, and evidence by the histological study. CPA also induced hepatic oxidative stress as indicated by significant elevation (P < 0.05) in malondialdehyde content, hydrogen peroxide (H2O2) generation, nitrite level, and the level of glutathione (GSH) peroxidase crashed in the CPA-treated group. GA enhanced the antioxidant defense system as indicated by significant elevation (P < 0.05) in GSH level, catalase activity, and GSH-S-transferase activity. Conclusions: Taken together, the result of this present study shows that GA has a protective effect on CPA-induced hepatotoxicity.

Abstract
Cyclophosphamide is a chemotherapeutic agent which was first discovered in experimental tumours in rats, and it has since been widely used to treat malignancies and severe manifestations of various auto-immune diseases. High-dose chemotherapy and continuous daily oral regimens are associated with significant toxicity profiles, but i.v. pulsed regimens have lowered the rates of adverse effects in rheumatological studies. Cyclophosphamide has been shown to be useful in the treatment of severe autoimmune conditions due to its powerful immunosuppressive ability; however, it remains a relatively underused modality in dermatology. This article reviews the current literature on cyclophosphamide and its clinical applications in dermatology.

Abstract
Abstract Cytotoxic chemotherapy, hormonal therapy and molecular targeted therapy are the three major classes of drugs used to treat breast cancer. Imaging modalities such as computed tomography (CT), magnetic resonance imaging (MRI), 18F-FDG positron emission tomography (PET)/CT and bone scintigraphy each have a distinct role in monitoring response and detecting drug toxicities associated with these treatments. The purpose of this article is to elucidate the various systemic therapies used in breast cancer, with an emphasis on the role of imaging in assessing treatment response and detecting treatment-related toxicities. Teaching Points • Cytotoxic chemotherapy is often used in combination with HER2-targeted and endocrine therapies. • Endocrine and HER2-targeted therapies are recommended in hormone-receptor- and HER2-positive cases. • CT is the workhorse for assessment of treatment response in breast cancer metastases. • Alternate treatment response criteria can help in interpreting pseudoprogression in metastasis. • Unique toxicities are associated with cytotoxic chemotherapy and with endocrine and HER2-targeted therapies.

Abstract
Cyclophosphamide (CYP) induces urothelial injury and causes excretion of cellular exudates at 24 h, followed by rapid restoration at 72 h. We investigated the role of urinary uroplakin II (UPII) levels in a CYP-induced cystitis model. For the purpose of this study, 10 controls and 26 CYP-injected female Sprague Dawley rats were killed at 24 h and 72 h postinjection. The vesical weight, severity of hematuria, and expression of UPII in the urinary bladder and urine were measured. CYP decreased the level of vesical UPII messenger RNA at 24 h, followed by rapid recovery at 72 h. Contrary to the negligible levels of urinary UPII and hematuria in controls, CYP treatment abruptly increased the excretion of urinary UPII at 24 h. The excretion had subsided at 72 h. Similarly, severe hematuria was observed at 24 h, with improvement at 72 h. However, some rats still exhibited hematuria at 72 h. CYP caused increase in vesical weight. The vesical weight at 24 h after CYP injection was negatively correlated with the vesical UPII level. Rats with significant hematuria demonstrated higher urinary UPII levels than those with insignificant hematuria. Vesical UPII could be an important barrier for early CYP-related injury, while the levels of urinary UPII may be associated with the severity of hematuria during dynamic periods in the urothelium.

Background Urothelial carcinoma (UC), also known as transitional cell carcinoma (TCC), of the bladder is the most common neoplasm affecting the canine urogenital system. To facilitate study of the disease in vitro, cell line models have been established from primary tumor biopsies. Their resemblance to the primary disease, however, has not been well defined. In the present study, we evaluated five canine UC cell lines via oligonucleotide array comparative genomic hybridization (oaCGH), fluorescence in situ hybridization (FISH), and gene expression analysis. Results Comparison of genome wide DNA copy number profiles of the cell lines with primary biopsy specimens revealed redundancies in genomic aberrations, indicating that the cell lines retain the gross genomic architecture of primary tumors. As in the primary tumors, gain of canine chromosomes 13 and 36 and loss of chromosome 19 were among the most frequent aberrations evident in the cell lines. FISH analysis revealed chromosome structural aberrations, including tandem duplications, bi-armed chromosomes, and chromosome fusions, suggesting genome instability during neoplastic transformation. Gene expression profiling highlighted numerous differentially expressed genes, including many previously shown as dysregulated in primary canine UC and human bladder cancer. Pathway enrichment analysis emphasized pathways suspected to be at the crux of UC pathogenesis, including xenobiotic and lipid compound metabolism. Conclusions These data support valid use of the canine UC cell lines evaluated by confirming they provide an accurate and practical means to interrogate the UC at a molecular level. Moreover, the cell lines may provide a valuable model for furthering our understanding of aberrant metabolic pathways in UC development.

Abstract
UNLABELLED Nephrotoxicity is a common adverse effect of many chemotherapeutic agents. The agents most commonly associated with chemotherapy-associated nephrotoxicity are methotrexate, semustine, streptozocin, mithramycin, and cisplatin. Certain chemotherapeutic agents have adverse effects on the kidneys and urothelium that can be visualized radiographically, including cystic change, interstitial nephritis, papillary necrosis, urothelial changes, haemorrhagic cystitis, acute tubular necrosis, and infarction. This review focuses on imaging features identifying complications of chemotherapy in the kidneys and collecting system and provides didactic cases to alert referring clinicians. TEACHING POINTS • Nephrotoxicity is a common adverse effect of many chemotherapeutic agents. • Chemotherapies have adverse renal and urothelial effects that can be visualized radiographically. • Crizotinib use can result in the development of complex renal cysts.

Abstract
AbstractCyclophosphamide (CP) treatment is associated with the risk of haemorrhagic cystitis (HC). Moreover, CP-induced HC is complicated by autonomic nervous system (ANS) dysfunction. Pemirolast is thought to be a mast cell stabiliser that inhibits the release of many inflammatory mediators and sensory neuropeptides, and thus, it may be considered a potential chemoprotective HC agent. The aim of the study was to indirectly estimate the effect of pemirolast in experimental HC by measuring ANS activity with the heart rate variability (HRV) method. In CP-treated rats, we found a decreasing trend of overall autonomic activity, together with an imbalance between the main components, and a dominant very low frequency (VLF) power component. Pemirolast treatment did not improve the total HRV power value or the main non-normalized HRV components. Moreover, CP-HC animals treated with pemirolast displayed a different disproportion of normalized spectral components as compared to both control and CP-HC animals without pemirolast treatment, with the balance between normalized low frequency (nLF) and normalized high frequency (nHF) shifted towards nLF. This finding, together with a relatively high VLF tension, indicates that the pemirolast treatment resulted in high sympathetic activity that may contribute to HC exacerbation; thus, this agent seems to be ineffective in CP-induced HC.

Abstract
Ifosfamide (IFO) is an alkylating nitrogen mustard, administrated as an antineoplasmic agent. It is characterized by its intense urotoxic action, leading to hemorrhagic cystitis. This side effect of IFO raises the requirement for the co-administration with sodium 2-sulfanylethanesulfonate (Mesna) aiming to avoid or minimize this effect. IFO and Mesna were administrated separately on rabbit's lymphocytes in vivo, which were later developed in vitro. Cytogenetic markers for sister chromatid exchanges (SCEs), proliferation rate index (PRI) and Mitotic Index were recorded. Mesna's action, in conjunction with IFO reduces the frequency of SCEs, in comparison with the SCEs recordings obtained when IFO is administered alone. In addition to this, when high concentrations of Mesna were administered alone significant reductions of the PRI were noted, than with IFO acting at the same concentration on the lymphocytes. Mesna significantly reduces IFO's genotoxicity, while when administered in high concentrations it acts in an inhibitory fashion on the cytostatic action of the drug.

Abstract
Hematopoietic stem cell transplantation (HSCT) is a curative treatment for several malignant and nonmalignant disorders. Busulfan (Bu) and cyclophosphamide (Cy) are the most commonly used alkylators in high-dose pretransplant conditioning for HSCT; a treatment that is correlated with drug-related toxicity and relapse. Pharmacogenetic investigations have shown that CYP450, as well as aldehyde dehydrogenase, are clearly involved with Cy metabolism and are associated with altered treatment response, Cy metabolism and the unique stem-cell sparing capacity. Moreover, glutathione-S-transferase isoenzymes have been associated with cellular outward transport of various alkylating agents, including Cy metabolites, melphalan, Bu and chlorambucil. A shift from genetic-based studies to whole-genome-based investigations of Cy- and Bu-associated markers may contribute to personalizing the conditioning therapy and enhancing the clinical outcome of HSCT.

Abstract
The glycine deportation system is an essential component of glycine catabolism in man whereby 400 to 800mg glycine per day are deported into urine as hippuric acid. The molecular escort for this deportation is benzoic acid, which derives from the diet and from gut microbiota metabolism of dietary precursors. Three components of this system, involving hepatic and renal metabolism, and renal active tubular secretion help regulate systemic and central nervous system levels of glycine. When glycine levels are pathologically high, as in congenital nonketotic hyperglycinemia, the glycine deportation system can be upregulated with pharmacological doses of benzoic acid to assist in normalization of glycine homeostasis. In congenital urea cycle enzymopathies, similar activation of the glycine deportation system with benzoic acid is useful for the excretion of excess nitrogen in the form of glycine. Drugs which can substitute for benzoic acid as substrates for the glycine deportation system have adverse reactions that may involve perturbations of glycine homeostasis. The cancer chemotherapeutic agent ifosfamide has an unacceptably high incidence of encephalopathy. This would appear to arise as a result of the production of toxic aldehyde metabolites which deplete ATP production and sequester NADH in the mitochondrial matrix, thereby inhibiting the glycine deportation system and causing de novo glycine synthesis by the glycine cleavage system. We hypothesize that this would result in hyperglycinemia and encephalopathy. This understanding may lead to novel prophylactic strategies for ifosfamide encephalopathy. Thus, the glycine deportation system plays multiple key roles in physiological and neurotoxicological processes involving glycine.

Abstract
The effects of Phyllanthus niruri hydroalcoholic extract and the isolated compounds quercetin, rutin, and gallic acid were examined in the mouse model of cyclophosphamide (CYP)-induced hemorrhagic cystitis (HC). HC was induced by a single CYP injection (300 mg/kg, IP), and the animals were evaluated 4 and 6 h after. Some animals were orally treated with the reference compound 2-mercaptoethane sodium sulfonate (Mesna) 80 mg/kg (30 min before CYP) and 160 mg/kg (2 h after CYP). Other groups were treated with P. niruri extract (30 and 50 mg/kg), or quercetin, rutin, and gallic acid (10 and 20 mg/kg), given orally, at the same intervals described for Mesna. P. niruri extract and its active components produced a significant attenuation of the nociception, edema, and hemorrhage evoked by CYP, which was similar to that seen for Mesna. Gallic acid and rutin displayed greater anti-inflammatory effects, whereas quercetin presented superior antinociceptive activities. Noteworthy is that P. niruri extract and compounds significantly reduced CYP-induced liver lipid peroxidation. Our results shed new light on the beneficial effects of P. niruri extract and its active compounds in attenuating the collateral effects elicited by the chemotherapeutic agent CYP.

Abstract
Cyclophosphamide (CP) is a commonly used anti-cancer drug which causes toxicity by its reactive metabolites. In this study we investigated the effect of Tinospora cordifolia on urotoxicity induced by acute dose of CP using Swiss albino mice model. Administration of an alcoholic extract of the plant T. cordifolia (Family: Menispermaceae) (200 mg/kg i.p.) for 5 days reduced CP (1.5 mmol/kg body wt. i.p.) induced urotoxicity as evident from the morphological analysis of bladder, decreased the relative bladder and liver weights and also decreased level of urea nitrogen and protein in blood as well as urine. Severely inflamed and dark coloured urinary bladders of the CP alone treated animals were found to be normalized by the treatment of T. cordifolia. GSH content, which was drastically reduced by CP administration in both bladder and liver was enhanced by treatment with T. cordifolia. Histopathological analysis of the bladder of CP alone-treated group showed severe necrotic damage where as the T. cordifolia-treated group showed normal bladder architecture. The lowered levels of cytokines IFN-γ, IL-2, after CP treatment were found to be increased in treated animals. At the same time the level of pro-inflammatory cytokine TNF-α, which was elevated during CP administration, was significantly reduced by extract administration. This study clearly demonstrates uroprotective role of T. cordifolia from CP induced toxicities by modulating GSH and pro-inflammatory cytokine levels.
