The development of a novel antioxidant-based antiemetic drug to improve quality of life during anticancer therapy. Biochem Biophys Rep 2022; 32:101363. [PMID: 36237446 PMCID: PMC9552029 DOI: 10.1016/j.bbrep.2022.101363] [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: 07/30/2022] [Revised: 09/30/2022] [Accepted: 10/04/2022] [Indexed: 11/09/2022] Open
Abstract
Anticancer agents can effectively treat several types of cancers but are often limited in clinical settings due to various adverse effects. In particular, nausea and vomiting are serious side effects that markedly reduce the patients' quality of life. Accordingly, the development of novel antiemetic drugs that lack side effects is crucial, given that most conventional antiemetic drugs are known to possess side effects. In addition, reactive oxygen species generated by anticancer agents are involved in nausea and vomiting; hence, appropriate antioxidants might also be effective toward nausea and vomiting. Silicon (Si)-based agents can abundantly generate antioxidant hydrogen in the intestine. Therefore, we assessed whether Si-based agents could be effective against nausea associated with anticancer agents in cisplatin-injected mice. We observed numerous neurons expressing c-Fos protein, a neuronal activity marker, in the nausea-associated regions of the dorsal medulla (area postrema, nuclei of the solitary tract, and dorsal vagal nuclei) 24 h after cisplatin injection. Conversely, mice fed a diet containing 2.5% Si-based agents showed a reduction in c-Fos-positive neurons. These findings revealed that the Si-based agent alleviated cisplatin-induced nausea. Si-based agents demonstrate potent antioxidant effects by producing hydrogen, which has no known side effects and will be a safer antiemetic agent and greatly help improve the quality of life of patients undergoing anticancer drug treatment. Si-based agent can continuously generate a large amount of hydrogen, which has an antioxidant effect. Cisplatin was used at a concentration that is not nephrotoxic and induces only nausea and vomiting. Si-based agent alleviated nausea and vomiting associated with cisplatin administration.

Comp Biochem Physiol C Toxicol Pharmacol 2022; 259:109395.

Abstract
Pharmaceuticals and personal care products are emerging environmental pollutants. Cisplatin, one of the most widely used platinum-based chemotherapeutic agents, has been found to contaminate aquatic environments. Using zebrafish embryos as a model, cisplatin was previously found to impair skin ionocytes and ion regulation. The purpose of this study was to further investigate how cisplatin damages ionocytes. Zebrafish embryos were exposed to cisplatin (0, 50, and 100 μM) for 96 h (4-100 h post-fertilization) and then stained with fluorescent dyes to reveal mitochondrial activity (rhodamine123), apoptosis (acridine orange), and oxidative stress (CellROX/MitoSOX) in ionocytes of living embryos. Results showed that cisplatin exposure decreased rhodamine 123-labeled ionocytes, induced oxidative stress in ionocytes, and promoted apoptosis in a concentration-dependent manner. Quantitative PCR analysis showed that mRNA levels of antioxidative genes (sod1, sod2, gpx1a, and cat) and an apoptotic gene (caps3a) were induced. In the time-course experiment at 96-98 h post-fertilization, cisplatin increased oxidative stress and apoptosis in ionocytes in a time-dependent manner. In conclusion, this study demonstrates that cisplatin exposure induces oxidative stress, mitochondrial damage, and apoptosis in ionocytes of zebrafish embryos.

Abstract
Cisplatin, a first-line chemotherapeutic agent commonly used to treat various solid tumors, induce severe adverse effects, especially nephrotoxicity, which largely limits its clinical application. However, the currently used measures to prevent nephrotoxicity are not ideal owing to the mechanisms underlying cisplatin-induced nephrotoxicity are not comprehensively understood. Herein, we examined the effects of silibinin on cisplatin-induced nephrotoxicity and found that silibinin exerted cytoprotection effects during cisplatin treatment in HEK293 cells and in a cisplatin-induced acute kidney injury (AKI) model. Mechanistically, silibinin ameliorated cisplatin-induced AKI via decreasing ROS-mediated MAPK signaling pathway activation, which was confirmed using the inhibitor N-acetylcysteine. Moreover, the protective effect of silibinin against cisplatin-induced ROS generation through the antioxidant transcription factor nuclear factor-erythroid 2-related factor 1 (Nfe2l1), rather than Nfe2l2, mediates HO1 expression. Furthermore, interference with the abundance of Nfe2l1 using siRNA or an overexpression plasmid enhanced or decreased the effect of cisplatin-induced apoptosis, respectively, in HEK293 cells. Interestingly, Nfe2l1 protein stability was more sensitive to cisplatin than that of Nfe2l2. More importantly, the mechanism that silibinin activates Nfe2l1-mediated antioxidant responses was confirmed in a cisplatin-induced AKI model. Silibinin rescued cisplatin-induced Nfe2l1 inhibition by regulating its transcription and post-translational modifications. Taken together, our results reveal a novel mechanism by which silibinin ameliorates cisplatin-induced AKI via activating Nfe2l1-mediated antioxidative response, which provides a new insights to protect patients receiving cisplatin-based cancer treatment against AKI.

Alleviation of Oral Exposure to Aflatoxin B1-Induced Renal Dysfunction, Oxidative Stress, and Cell Apoptosis in Mice Kidney by Curcumin. Antioxidants (Basel) 2022; 11:antiox11061082. [PMID: 35739979 PMCID: PMC9219944 DOI: 10.3390/antiox11061082] [Citation(s) in RCA: 30] [Impact Index Per Article: 15.0] [Reference Citation Analysis] [Abstract] [Track Full Text] [Download PDF] [Figures] [Journal Information] [Subscribe] [Scholar Register] [Received: 05/07/2022] [Revised: 05/23/2022] [Accepted: 05/27/2022] [Indexed: 02/06/2023] Open
Abstract
Aflatoxin B1 is a contaminant widely found in food and livestock feed, posing a major threat to human and animal health. Recently, much attention from the pharmaceutical and food industries has been focused on curcumin due to its strong antioxidant capacity. However, the therapeutic impacts and potential mechanisms of curcumin on kidney damage caused by AFB1 are still incomplete. In this study, AFB1 triggered renal injury in mice, as reflected by pathological changes and renal dysfunction. AFB1 induced renal oxidative stress and interfered with the Keap1–Nrf2 pathway and its downstream genes (CAT, SOD1, NQO1, GSS, GCLC, and GCLM), as manifested by elevated oxidative stress metabolites and reduced antioxidant enzymes activities. Additionally, AFB1 was found to increase apoptotic cells percentage in the kidney via the TUNEL assay, along with increased expression of Cyt-c, Bax, cleaved-Caspase-3, Caspase-9, and decreased expression of Bcl-2 at the transcriptional and protein levels; in contrast, for mice given curcumin, there was a significant reversal in kidney coefficient, biochemical parameters, pathological changes, and the expression of genes and proteins involved in oxidative stress and apoptosis. These results indicate that curcumin could antagonize oxidative stress and apoptosis to attenuate AFB1-induced kidney damage.

Abstract
One of the main antineoplastic chemotherapy medications is cisplatin, of which nephropathy is a major side effect. In this current study, we aim to investigate the molecular protective effect of Spirulina platensis (SP) on cisplatin-induced nephrotoxicity. In total, 48 healthy male albino rats were allocated into 4 groups. Group 1 received saline intraperitoneally (IP) twice per week (normal rats). Group 2 received SP (100 mg/kg BW orally). Group 3 were injected with cisplatin (1.5 mg/kg IP) twice per week. Group 4 received SP and on the 4th day received cisplatin (1.5 mg/kg IP) for 21 days. After 3 weeks of experiment, blood and renal tissues were taken for serum analysis, gene expression using qRT-polymerase chain reaction, and renal histopathology. As per our findings, it was found that SP significantly ameliorated the alterations in body weight, relative kidney weight, and the disturbance in examined renal markers. Furthermore, SP recovered and restored cisplatin-induced oxidative stress biomarkers (MDA and NO) and antioxidant activity (SOD and GSH) and cisplatin-induced upregulation in the gene expression of TNF-α, inducible nitric oxide synthase, TGF1-β, IL-1β, and IL-6. Interestingly, these gene expressions were ameliorated by the SP pre-administration. Furthermore, cisplatin upregulated pro-apoptotic gene Bax, whereas it downregulated anti-apoptotic gene Bcl2. Interestingly, SP mitigated this alteration in apoptosis and anti-apoptotic associated genes. Renal histopathology revealed the protective impacts of SP against cisplatin-induced severe glomerular congestion, hemorrhage, inflammatory cell infiltration, degeneration, and severe necrosis in renal glomeruli and tubules. In conclusion, SP has a protective effect against cisplatin-induced renal damage through modulating oxidative stress and anti-inflammatory, anti-necrotic, and anti-apoptotic-associated genes.

Abstract
Two newly synthesized 4-hydroxycoumarin bidentate ligands (L1 and L2) and their palladium(II) complexes (C1 and C2) were screened for their biological activities, in vitro and in vivo. Structures of new compounds were established based on elemental analysis, 1H NMR, 13C NMR, and IR spectroscopic techniques. The obtained compounds were tested for their antioxidative and cytotoxic activities and results pointed to selective antiradical activity of palladium(II) complexes towards •OH and -•OOH radicals and anti-ABTS (2,2′-Azino-bis(3-ethylbenzothiazoline-6-sulfonic acid) cation radical) activity comparable to that of ascorbate. Results indicated the effect of C1 and C2 on the enzymatic activity of the antioxidative defense system. In vitro cytotoxicity assay performed on different carcinoma cell lines (HCT166, A375, and MIA PaCa-2), and one healthy fibroblast cell line (MRC-5) showed a cytotoxic effect of both C1 and C2, expressed as a decrease in carcinoma cells' viability, mostly by induction of apoptosis. In vivo toxicity tests performed on zebrafish embryos indicated different effects of C1 and C2, ranging from adverse developmental effect to no toxicity, depending on tested concentration. According to docking studies, both complexes (C1 and C2) showed better inhibitory activity in comparison to other palladium(II) complexes.

Abstract
This review summarizes the adverse effects on the central and/or peripheral nervous systems that may occur in response to antineoplastic drugs. In particular, we describe the neurotoxic side effects of the most commonly used drugs, such as platinum compounds, doxorubicin, ifosfamide, 5-fluorouracil, vinca alkaloids, taxanes, methotrexate, bortezomib and thalidomide. Neurotoxicity may result from direct action of compounds on the nervous system or from metabolic alterations produced indirectly by these drugs, and either the central nervous system or the peripheral nervous system, or both, may be affected. The incidence and severity of neurotoxicity are principally related to the dose, to the duration of treatment, and to the dose intensity, though other factors, such as age, concurrent pathologies, and genetic predisposition may enhance the occurrence of side effects. To avoid or reduce the onset and severity of these neurotoxic effects, the use of neuroprotective compounds and/or strategies may be helpful, thereby enhancing the therapeutic effectiveness of antineoplastic drug.

Abstract
Background Nephrotoxicity of cisplatin has been recognized since its introduction more than 25 years ago. However, despite intense efforts to develop less toxic and equally effective alternatives, cisplatin continues to be widely prescribed. Aim and Objectives. The study is aimed at assessing the possible prophylactic effect of coenzyme Q10 (CoQ10) and alpha-lipoic acid (ALA) (separately or in combination) on experimentally cisplatin-induced nephrotoxicity. Subjects and Methods. An experimental study was performed on adult male albino rats (n = 40), weighing 200–250 g. Rats were randomly divided into 5 groups: group I (normal saline control), group II (cisplatin control), group III (CoQ10 and cisplatin), group IV (ALA and cisplatin), and group V (CoQ10, ALA, and cisplatin). CoQ10 and/or ALA were given as pretreatment for 9 days, followed by cisplatin injection in the 10th day of the study, followed by a short posttreatment course for 3 days. Renal functions, tissue antioxidant activity, and inflammatory markers (tumor necrosis factor, TNF) were estimated along with histopathological study. Results Renal function tests and urinary proteins were significantly higher within group II compared with other groups (P value <0.001). Creatinine clearance was significantly higher with combination therapy (group V compared to other groups). Both TNF and malondialdehyde (MDA) were significantly higher within group II whereas GSH content, catalase, and superoxide dismutase (SOD) were significantly lower in group II. MDA level was significantly lower when combination therapy was used. Marked renal damage was histologically detected in the cisplatin group, whereas the least renal damage was noticed in the combination group. Conclusion The study confirmed the role of antioxidants in preventing nephrotoxicity caused by cisplatin; the prophylactic effect of combined therapy with CoQ10 and ALA is superior to that of monotherapy.

Abstract
Cisplatin is a potent anti-cancer drug, however, its accompanied organ-toxicity hampers its clinical applications. Cisplatin-associated kidney injury is known to result from its accumulation in the renal tubule with excessive generation of reactive oxygen species. In this study, we encapsulated honokiol, a natural lipophilic polyphenol constituent extracted from Magnolia officinalis into nano-sized liposomes (nanosome honokiol) and examined the in vivo countering effects on cisplatin-induced renal injury. We observed that 5 mg/kg body weight. nanosome honokiol was the lowest effective dosage to efficiently restore renal functions of cisplatin-treated animals. The improvement is likely due the maintenance of cellular localization of cytochrome c and thus preserves mitochondria integrity and their redox activity, which as a consequence, reduced cellular oxidative stress and caspase 3-associated apoptosis. These improvements at the cellular level are later reflected on the observed reduction of kidney inflammation and fibrosis. In agreement with our earlier in vitro study showing protective effects of honokiol on kidney cell lines, we demonstrated further in the current study, that nanosuspension-formulated honokiol provides protective effects against cisplatin-induced chronic kidney damages in vivo. Our findings not only benefit cisplatin-receiving patients with reduced renal side effects, but also provide potential alternative and synergic solutions to improve clinical safety and efficacy of cisplatin treatment on cancer patients.

Abstract
Leber's hereditary optic neuropathy (LHON) is a maternally inherited mitochondrial disorder characterized by acute bilateral vision loss. The pathophysiology involves reactive oxygen species (ROS), which can be affected by medications. This article reviews the evidence for medications with demonstrated and theoretical effects on mitochondrial function, specifically in relation to increased ROS production. The data reviewed provides guidance when selecting medications for individuals with LHON mutations (carriers) and are susceptible to conversion to affected. However, as with all medications, the proven benefits of these therapies must be weighed against, in some cases, purely theoretical risks for this unique patient population.

Abstract
Cisplatin is a potent anti-cancer drug that has been widely used in the treatment of various cancers; however, cisplatin administration results in severe nephrotoxicity and impedes its clinical applications. In this study, we showed that honokiol, a polyphenol constituent extracted from Magnolia officinalis exhibited a short-term protective effect against cisplatin-induced damages in renal epithelial cells in vitro. The protective effects of honokiol were resulted from the combination of (1) reduced cellular oxidative stress ranging from 53 to 32% reduction during a 24-h incubation, (2) the maintenance of cellular antioxidant capacity and (3) the stabilization of cytoskeletal structure of the kidney epithelial cells. By promoting the polymerization of actin (1.6-fold increase) and tubulin (1.8-fold increase) cytoskeleton, honokiol not only maintained epithelial cell morphology, but also stabilized cellular localizations of tight junction protein Occludin and adhesion junction protein E-Cadherin. With stabilized junction protein complexes and structural polymerized cytoskeleton network, honokiol preserved epithelial cell polarity and morphology and thus reduced cisplatin-induced cell disruption and damages. Our data demonstrated for the first time that honokiol could counteract with cisplatin-induced damages in renal epithelial cells in vitro, future in vivo studies would further validate the potential clinical application of honokiol in cisplatin-based cancer treatments with reduced nephrotoxicity.

Abstract
Oxidative stress is one of the important mechanisms of cisplatin-induced nephrotoxicity. Therefore, this study was designed to explore the potential protective effects of morin and/or hesperidin on oxidative stress in cisplatin-induced nephrotoxicity. This study was performed on 42 Wistar rats. Rats were divided into seven groups: control, morin, hesperidin, cisplatin, cisplatin + morin, cisplatin + hesperidin, and cisplatin + morin + hesperidin. Morin and/or hesperidin were given for 10 consecutive days by oral gavage and on the 4th day a single dose of cisplatin (7 mg/kg) was injected intraperitoneally. After administrations, on the 11th day of the experiment the animals were killed, and malondialdehyde (MDA), nitric oxide (NOx), glutathione (GSH) levels and myeloperoxidase (MPO), catalase (CAT), superoxide dismutase (SOD) activity were measured. Cisplatin-treated rats showed increased levels of MDA, and decreased levels of NOx also activity of CAT. Morin and/or hesperidin pretreatment prevent oxidative stress in kidney tissue, while they increase the NOx level, CAT activity, and decrease MPO activity. In conclusion, morin + hesperidin pretreatment may have a significant potential for protection of cisplatin-induced nephrotoxicity.

Abstract
Cisplatin is one of the most widely-used drugs to treat cancers. However, its nephrotoxic and ototoxic side-effects remain major clinical limitations. Recent studies have improved our understanding of the molecular mechanisms of cisplatin-induced nephrotoxicity and ototoxicity. While cisplatin binding to DNA is the major cytotoxic mechanism in proliferating (cancer) cells, nephrotoxicity and ototoxicity appear to result from toxic levels of reactive oxygen species and protein dysregulation within various cellular compartments. In this review, we discuss molecular mechanisms of cisplatin-induced nephrotoxicity and ototoxicity. We also discuss potential clinical strategies to prevent nephrotoxicity and ototoxicity and their current limitations.

Abstract
Background Cisplatin (CIS) is one of the most effective anticancer drug used in the treatment of several solid tumors .Its use is limited by its nephrotoxicity. The present study was designed to assess the role of a natural product resveratrol (RSVL) on sensitization of mammary carcinoma (Ehrlich ascites carcinoma) to the action of CIS and the possible protective effect against CIS-induced nephrotoxicity in rats. Methods The percent survival of female tumor bearing mice was used for determination the cytotoxic activity of CIS in the presence or the absence of RSVL. Uptake and cell cycle effect, serum creatinine (CREA), blood urea nitrogen (BUN), Reduced Glutathione (GSH) and histopatholgical examination of kidney tissues after CIS and/or RSVL therapy were also investigated. Results RSVL increased the intracellular level of CIS in EAC cells and there was a strong correlation between the high cellular level of CIS and its cytotoxicity. CIS at a dose level of 5 mg/kg increased the mean survival time of female tumor bearing mice to 25 days compared with 17 days for tumor-bearing control mice. Administration of RSVL at a dose level of 25 mg/kg simultaneously with CIS increased the mean survival time to 48 days with 60% survival of the tumor-bearing animals. Cell cycle analysis of tumor cells showed that CIS treatment decreases the proliferation index of tumor cells while in presence of RSVL there was more significant inhibitions. Also, CIS treatment caused increase in level of creatinine and blood urea with significant decrease in the GSH level. While, in the presence of RSVL, level of creatinine and blood urea restored to control level. Conclusion This study suggests that RSVL could increase the cytotoxic activity of CIS and protect against its nephrotoxicity.

Abstract
PURPOSE Cisplatin is a widely used anti-cancer drug in the treatment of a wide range of tumors; however, its application is limited by nephrotoxicity, which is affected by oxidative stress. We have reported that molecular hydrogen (H(2)) acts as an efficient antioxidant (Ohsawa et al. in Nat Med 13:688-694, 2007). Here we show that hydrogen efficiently mitigates the side effects of cisplatin by reducing oxidative stress. METHODS Mice were administered cisplatin followed by inhaling hydrogen gas (1% H(2) in air). Furthermore, instead of inhaling hydrogen gas, we examined whether drinking water containing hydrogen (hydrogen water; 0.8 mM H(2) in water) is applicable by examining oxidative stress, mortality, and body-weight loss. Nephrotoxicity was assessed by morphological changes, serum creatinine and blood urea nitrogen (BUN) levels. RESULTS Inhalation of hydrogen gas improved mortality and body-weight loss caused by cisplatin, and alleviated nephrotoxicity. Hydrogen was detected in blood when hydrogen water was placed in the stomach of a rat. Consuming hydrogen water ad libitum also reduced oxidative stress, mortality, and body-weight loss induced by cisplatin in mice. Hydrogen water improved metamorphosis accompanying decreased apoptosis in the kidney, and nephrotoxicity as assessed by serum creatinine and BUN levels. Despite its protective effects against cisplatin-induced toxicity, hydrogen did not impair anti-tumor activity of cisplatin against cancer cell lines in vitro and tumor-bearing mice in vivo. CONCLUSION Hydrogen has potential for improving the quality of life of patients during chemotherapy by efficiently mitigating the side effects of cisplatin.

Abstract
Cisplatin is a DNA-damaging anti-cancer agent that is widely used to treat a range of tumour types. Despite its clinical success, cisplatin treatment is still associated with a number of dose-limiting toxic side effects. The purpose of this study was to clarify the molecular events that are important in the anti-tumour activity of cisplatin, using gene expression profiling techniques. Currently, our incomplete understanding of this drug's mechanism of action hinders the development of more efficient and less harmful cisplatin-based chemotherapeutics. In this study the effect of cisplatin on gene expression in human foreskin fibroblasts has been investigated using human 19K oligonucleotide microarrays. In addition its clinically inactive isomer, transplatin, was also tested. Dualfluor microarray experiments comparing treated and untreated cells were performed in quadruplicate. Cisplatin treatment was shown to significantly up- or down-regulate a consistent subset of genes. Many of these genes responded similarly to treatment with transplatin, the therapeutically inactive isomer of cisplatin. However, a smaller proportion of these transcripts underwent differential expression changes in response to the two isomers. Some of these genes may constitute part of the DNA damage response induced by cisplatin that is critical for its anti-tumour activity. Ultimately, the identification of gene expression responses unique to clinically active compounds, like cisplatin, could thus greatly benefit the design and development of improved chemotherapeutics.

Abstract
Arylamine N-acetyltransferase 1 (NAT1) is a phase II xenobiotic-metabolizing enzyme that plays an important role in the biotransformation of aromatic drugs and carcinogens. NAT1 activity has long been associated with susceptibility to various cancers. Evidence for a role of NAT1 in malignant progression has also been obtained, particularly for breast and prostate cancer. Cisplatin is widely used in chemotherapy against human cancers, and it is thought to act principally by forming DNA adducts. However, recent studies have suggested that some of the pharmacological and/or toxicological effects of cisplatin may be due to the direct targeting and inhibition of certain cellular enzymes. We show here that the exposure of breast cancer cells, known to express functional NAT1 enzyme, to therapeutically relevant concentrations of cisplatin impairs the catalytic activity of endogenous NAT1. Endogenous NAT1 was also found to be inactivated, in vivo, in the tissues of mice treated with cisplatin. Mechanistic studies with purified human NAT1 indicated that this inhibition resulted from the irreversible formation of a cisplatin adduct with the active-site cysteine residue of the enzyme. Kinetic studies suggested that NAT1 interacts rapidly with cisplatin, with a second-order rate inhibition constant of 700 M(-1) min(-1). This rate constant is one the highest ever reported for the reaction of cisplatin with a biological macromolecule. Few enzymes have been clearly shown to be inactivated by cisplatin. We provide here molecular and cellular evidence suggesting that NAT1 is one of the targets of cisplatin in cells.

Abstract
The effect of dehydrotarplatin (DTP), a new antineoplastic drug analogous to cisplatin, and its metabolite (Triacid) on the hepatic, renal and testicular CYP and antioxidant enzymes of male rats was investigated. The rats were treated i.p. with a single dose of DTP (25 mg kg(-1) day(-1)) or Triacid (17.5 mg kg(-1) day(-1)) and analysed 3 or 7 days post treatment. Three days after treatment, both drugs reduced body and liver weights, which partially recovered the control level after 7 days. DTP and, to a less extent, Triacid caused a depletion of plasmatic testosterone content and a down regulation in the liver of androgen dependent male specific CYP 2C11, but not of CYP 1A and 2E1, as determined by a significant decrease of 2alpha- and 16alpha-testosterone hydroxylase activities (markers for CYP 2C11) and of apoprotein immunoreactive with anti-rat CYP 2C11 antibodies. However, the activity of testicular 17alpha-progesterone hydroxylase, a key reaction in steroidogenesis, was not altered by these drugs. The DTP and Triacid administration did not cause any alteration of the plasmatic urea nitrogen and creatinine, known as markers of kidney toxicity. However, treatment with DTP, not Triacid, either 3 and 7 days post treatment, caused in the kidney microsomes a significant increase of the total CYP content, the CYP 4A-dependent (omega)- and (omega - 1)-lauric acid hydroxylase activities and apoprotein immunoreactive with anti-rat CYP 4A1. The present study also examined the enzymatic antioxidant status of kidney and liver. Neither DTP nor Triacid administration induced, with respect to control values, any alteration of hepatic and renal glutathione reductase, glutathione S-transferase, catalase, superoxide dismutase activities, hepatic GSH level and renal microsomal lipid peroxidation level. Among the antioxidant enzymes assayed, only the renal activity of glutathione peroxidase was significantly increased after DTP but not Triacid treatment. These results indicate that DTP at a dose of 25 mg/kg and Triacid cause a feminization of the CYP enzymes in male rat liver similar to that reported for cisplatin when administered at a low dose (5 mg/kg). However, unlike cisplatin, DTP and its metabolite were unable to enhance BUN and creatinine and cause any depression of CYP activities and antioxidant enzymes in the kidney, suggesting that DTP may have low or even no potential in inducing nephrotoxicity.

Abstract
Bacillus anthracis lethal toxin (LT) produces symptoms of anthrax in mice and induces rapid lysis of macrophages derived from certain inbred strains. LT is comprised of a receptor binding component, protective antigen (PA), which delivers the enzymatic component, lethal factor (LF), into cells. We found that mouse macrophages were protected from toxin by the antitumor drug cis-diammineplatinum (II) dichloride (cisplatin). Cisplatin was shown to inhibit LT-mediated cleavage of cellular mitogen-activated protein kinases (MEKs) without inhibiting LF's in vitro proteolytic activity. Cisplatin-treated PA lost 100% of its ability to function in toxicity assays when paired with untreated LF, despite maintaining the ability to bind to cells. Cisplatin-treated PA was unable to form heptameric oligomers required for LF binding and translocation. The drug was shown to modify PA in a reversible noncovalent manner. Not surprisingly, cisplatin also blocked the actions of anthrax edema toxin and of LF-Pseudomonas aeruginosa exotoxin A fusion peptide (FP59), both of which require PA for translocation. Treatment of BALB/cJ mice or Fischer F344 rats with cisplatin at biologically relevant concentrations completely protected the animals from a coadministered lethal dose of LT. However, treatment with cisplatin 2 hours before or after animals received a lethal bolus of toxin did not protect them.

Abstract
This study aims to elucidate the molecular mechanism(s) of cisplatin nephrotoxicity and the possible protective effects of antioxidant food supplementation on this toxicity. Twenty eight rats were used throughout the study. Cisplatin was administered intraperitoneally (i.p.) in a single dose (10 mg kg(-1)). Antioxidant food supplementation was started 3 days before cisplatin treatment. In each group (control, cisplatin, cisplatin plus dried black grape and cisplatin plus tomato juice), there were seven animals. Rats were killed 72 h after treatment. The kidneys were removed and prepared for biochemical and histopathological investigations. Oxidant (sensitivity to oxidation, xanthine oxidase enzyme and malondialdehyde level) and antioxidant (superoxide dismutase, glutathione peroxidase and catalase enzymes, and antioxidant potential value) parameters were measured in kidney tissues of the groups. Histopathological examination was also performed. Significant decreases were measured in the renal activities of catalase and glutathione peroxidase enzymes. There was, however, a significant increase in the activity of xanthine oxidase enzyme in the cisplatin-treated animals compared with the control group. The kidney tissue malondialdehyde levels were found to be increased, but sensitivity to oxidation and antioxidant potential values to be decreased in the cisplatin group. In the food supplemented groups, it has been observed that black grape eliminated oxidant stress by increasing antioxidant potential, but tomato did not. Histopathological examination results also revealed significant damage in the kidney tissues from the cisplatin-treated rats. In the black grape group, significant improvements were observed compared with the cisplatin group. In the tomato group, there were also some improvements but to a lesser degree compared with the black grape group. The results suggest that cisplatin treatment causes significant oxidant load to the kidneys through both xanthine oxidase activation and impaired antioxidant defense system, which resulted in accelerated oxidation reactions in the kidney tissue. It is proposed that supplementation of some foods such as black grape which has resveratrol as an antioxidant can provide significant protection against cisplatin nephrotoxicity.

Abstract
Liver fatty acid binding protein (L-FABP) contains amino acids that are known to possess antioxidant function. In this study, we tested the hypothesis that L-FABP may serve as an effective endogenous cytoprotectant against oxidative stress. Chang liver cells were selected as the experimental model because of their undetectable L-FABP mRNA level. Full-length L-FABP cDNA was subcloned into the mammalian expression vector pcDNA3.1 (pcDNA-FABP). Chang cells were stably transfected with pc-DNA-FABP or vector (pcDNA3.1) alone. Oxidative stress was induced by incubating cells with 400 micromol/L H2O2 or by subjecting cells to hypoxia/reoxygenation. Total cellular reactive oxygen species (ROS) was determined using the fluorescent probe DCF. Cellular damage induced by hypoxia/reoxygenation was assayed by lactate dehydrogenase (LDH) release. Expression of L-FABP was documented by regular reverse transcription polymerase chain reaction (RT-PCR), real-time RT-PCR, and Western blot. The pcDNA-FABP-transfected cells expressed full-length L-FABP mRNA, which was absent from vector-transfected control cells. Western blot showed expression of 14-kd L-FABP protein in pcDNA-FABP-transfected cells, but not in vector-transfected cells. Transfected cells showed decreased DCF fluorescence intensity under oxidative stress (H2O2 and hypoxia/reoxygenation) conditions versus control in inverse proportion to the level of L-FABP expression. Lower LDH release was observed in the higher L-FABP-expressed cells in hypoxia/reoxygenation experiments. In conclusion, we successfully transfected and cloned a Chang liver cell line that expressed the L-FABP gene. The L-FABP-expressing cell line had a reduced intracellular ROS level versus control. This finding implies that L-FABP has a significant role in oxidative stress.
