Abstract
Methotrexate (MTX) is a folic acid reductase inhibitor that manages various malignancies as well as immune-mediated inflammatory chronic diseases. Despite being frequently prescribed, MTX's severe multiple toxicities can occasionally limit its therapeutic potential. Intestinal toxicity is a severe adverse effect associated with the administration of MTX, and patients are significantly burdened by MTX-provoked intestinal mucositis. However, the mechanism of such intestinal toxicity is not entirely understood, mechanistic studies demonstrated oxidative stress and inflammatory reactions as key factors that lead to the development of MTX-induced intestinal injury. Besides, MTX causes intestinal cells to express pro-inflammatory cytokines like interleukin-6 (IL-6) and tumor necrosis factor-alpha (TNF-α), which activate nuclear factor-kappa B (NF-κB). This is followed by the activation of the Janus kinase/signal transducer and activator of the transcription3 (JAK/STAT3) signaling pathway. Moreover, because of its dual anti-inflammatory and antioxidative properties, nuclear factor erythroid-2-related factor 2/heme oxygenase-1 (Nrf2/HO-1) has been considered a critical signaling pathway that counteracts oxidative stress in MTX-induced intestinal injury. Several agents have potential protective effects in counteracting MTX-provoked intestinal injury such as omega-3 polyunsaturated fatty acids, taurine, umbelliferone, vinpocetine, perindopril, rutin, hesperidin, lycopene, quercetin, apocynin, lactobacillus, berberine, zinc, and nifuroxazide. This review aims to summarize the potential redox molecular mechanisms of MTX-induced intestinal injury and how they can be alleviated. In conclusion, studying these molecular pathways might open the way for early alleviation of the intestinal damage and the development of various agent plans to attenuate MTX-mediated intestinal injury.

Abstract
Methotrexate (MTX) is an inhibitor of folic acid reductase used in managing a variety of malignancies. Testicular injury by MTX is one of its serious adverse effects. The current investigation aims to assess the protective effects of diacerein (DIA) on testicular injury by MTX and clarify the possible underlying mechanisms. Testicular injury in rats was induced by a single injection of 20 mg/kg body weight of MTX. DIA was given in 25 mg/kg body weight/day and 50 mg/kg body weight/day doses for 10 days. Compared to the MTX group, DIA attenuated testicular intoxication as evidenced by improvement of testicular histopathological abnormalities and increased serum testosterone and luteinizing hormone. DIA attenuated testicular oxidative stress changes by lowering testicular MDA and boosting GSH content and SOD activity. Moreover, administration of DIA attenuated MTX-induced testicular inflammation, as proved by decreased TNF-α and IL-6. At the molecular level, DIA induced significant upregulation in Nrf2, HO-1, PPAR-γ, and cytoglobin protein expression. The present results proved that DIA, in a dose-dependent manner, exhibited notable amelioration of testicular toxicity induced by MTX through augmentation of anti-inflammatory and antioxidant effects combined by upregulating Nrf2/HO-1, PPAR-γ, and cytoglobin signaling.

Bioactive Compounds Protect Mammalian Reproductive Cells from Xenobiotics and Heat Stress-Induced Oxidative Distress via Nrf2 Signaling Activation: A Narrative Review. Antioxidants (Basel) 2024; 13:597. [PMID: 38790702 PMCID: PMC11118937 DOI: 10.3390/antiox13050597] [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: 04/03/2024] [Revised: 05/08/2024] [Accepted: 05/10/2024] [Indexed: 05/26/2024] Open
Abstract
Oxidative stress occurs when there is an imbalance between the production of reactive oxygen species (ROS) and the body's antioxidant defenses. It poses a significant threat to the physiological function of reproductive cells. Factors such as xenobiotics and heat can worsen this stress, leading to cellular damage and apoptosis, ultimately decreasing reproductive efficiency. The nuclear factor erythroid 2-related factor 2 (Nrf2) signaling pathway plays a crucial role in defending against oxidative stress and protecting reproductive cells via enhancing antioxidant responses. Dysregulation of Nrf2 signaling has been associated with infertility and suboptimal reproductive performance in mammals. Recent advancements in therapeutic interventions have underscored the critical role of Nrf2 in mitigating oxidative damage and restoring the functional integrity of reproductive cells. In this narrative review, we delineate the harmful effects of heat and xenobiotic-induced oxidative stress on reproductive cells and explain how Nrf2 signaling provides protection against these challenges. Recent studies have shown that activating the Nrf2 signaling pathway using various bioactive compounds can ameliorate heat stress and xenobiotic-induced oxidative distress and apoptosis in mammalian reproductive cells. By comprehensively analyzing the existing literature, we propose Nrf2 as a key therapeutic target for mitigating oxidative damage and apoptosis in reproductive cells caused by exposure to xenobiotic exposure and heat stress. Additionally, based on the synthesis of these findings, we discuss the potential of therapies focused on the Nrf2 signaling pathway to improve mammalian reproductive efficiency.

Abstract
Studies have identified Coenzyme Q10 (CoQ10) as a promising agent in improving idiopathic male infertility; however, its role in chemically or environmentally induced testicular dysfunction is not well-established. We investigated the potential of CoQ10 to attenuate methotrexate (MTX)-induced testicular damage and to identify molecular targets of CoQ10 effects. Wistar rats received a single intraperitoneal dose of 20 mg/kg MTX on the fifth day of the 10-day experimental protocol. 100 mg/kg CoQ10 was given orally daily for ten days, alone or combined with MTX. The testes of MTX-treated animals showed thickened tunica albuginea, distortion of seminiferous tubules with a marked reduction of germinal lining, a few primary spermatocytes with no spermatozoa, apoptotic cells, congested sub-capsular and interstitial blood vessels, and interstitial edema. Reduction of reproductive hormones and increased oxidative, inflammatory, and apoptotic biomarkers levels were also seen in the MTX-treated rats. CoQ10 + MTX-treated rats were protected against MTX-induced testicular histological changes and showed improvement in testosterone, luteinizing-, and follicle-stimulating hormone serum levels compared to the MTX group. The testes of the CoQ10 + MTX-treated rats showed reduced malondialdehyde, myloperoxidase, tumor necrosis factor -α, interleukin-6 and -1β and Bax: Bcl2 ratio and enhanced glutathione, and catalase compared to MTX alone. CoQ10 enhanced MTX-induced downregulation of Nrf2 and PPAR-γ signaling and modulated its downstream targets, the inducible nitric oxide synthase, NF-κB, Bax, and Bcl2. In conclusion, CoQ10 targeted the Nrf2-PPAR-γ signaling loop and its downstream pathways, mitigating MTX-induced oxidative stress-related damages and alleviating the testicular dysfunction MTX caused. Our data suggest Nrf2-PPAR-γ signaling as a potential therapeutic target in testicular toxicity, where oxidative stress, inflammation, and apoptosis trigger damage.

Abstract
OBJECTIVES Methotrexate (MTX) is an antimetabolite agent widely used to manage a variety of tumors and autoimmune diseases. Nonetheless, MTX-induced intestinal intoxication is a serious adverse effect limiting its clinical utility. Inflammation and oxidative stress are possible mechanisms for MTX-induced intestinal toxicity. Vinpocetine (VNP) is a derivative of the alkaloid vincamine with potent anti-inflammatory and antioxidant effects. The current study investigated the protective intestinal impact of VNP in attenuating MTX-induced intestinal intoxication in rats. MATERIALS AND METHODS VNP was administered orally in a dose of 20 mg/kg, while MTX was injected intraperitoneal in a dose of 20 mg/kg. RESULTS VNP administration attenuated drastic histological changes induced by MTX and preserved both normal villus and crypt histology. VNP significantly attenuated oxidative injury by upregulating intestinal Nrf2 and HO-1 expression. VNP attenuated inflammation by reducing MPO, NO2-, TNF-α, and IL-1β levels mediated by downregulating NF-κB, NDAPH-oxidase, IRF3, p-JAK-1, and p-STAT-3 expressions. Moreover, VNP potently counteracted intestinal necroptosis by effectively downregulating RIPK1, RIPK3, MLKL, and caspase-8 proteins. CONCLUSION Therefore, VNP may represent a promising approach that can attenuate intestinal toxicity in patients receiving MTX.

Abstract
Methotrexate (MTX) has long manifested therapeutic efficacy in several neoplastic and autoimmune disorders. However, MTX-associated intestinal toxicity restricts the continuation of treatment. Nifuroxazide (NIF) is an oral antibiotic approved for gastrointestinal infections as an effective antidiarrheal agent with a high safety profile. The current study was designed to explore the potential efficacy of NIF in alleviating intestinal toxicity associated with MTX chemotherapy with the elucidation of the proposed molecular mechanisms. Rats were administered NIF (50 mg/kg; p.o.) for ten days. On day five, a single i.p. injection of MTX (20 mg/kg) was given to induce intestinal intoxication. At the end of the experiment, duodenal tissue samples were isolated for biochemical, Western blotting, immunohistochemical (IHC), and histopathological analysis via H&E, PSA, and Alcian blue stains. NIF showed antioxidant enteroprotective effects against MTX intestinal intoxication through enhanced expression of the redox-sensitive signals of PPAR-γ, SIRT1, and Nrf2 estimated by IHC. Moreover, NIF down-regulated the pro-inflammatory cytokines (TNF-α, IL-1β, IL-6), NF-κB protein expression, and the phosphorylation of JAK1/STAT3 proteins, leading to mitigation of intestinal inflammation. In accordance, the histological investigation revealed that NIF ameliorated the intestinal pathological changes, preserved the goblet cells, and reduced the inflammatory cells infiltration. Therefore, NIF could be a promising candidate for adjunctive therapy with MTX to mitigate the associated intestinal injury and increase its tolerability.

Abstract
Cisplatin is a chemotherapeutic agent usually used in treating different patterns of malignancies. One of the significant apparent complications of cisplatin chemotherapy is brain toxicity. The present study was conducted to evaluate the protective effects of lansoprazole on cisplatin-induced cortical intoxication. Thirty-two rats were allocated into four groups (8 rats/group); group I: received only a vehicle for 10 days, group II: lansoprazole was administered (50 mg/kg) via oral gavage for 10 days, group III: On 5th day of the experiment, rats were given cisplatin (10 mg/kg) i.p. once to induce cortical injury. Group IV: rats were given lansoprazole for 5 days before cisplatin and 5 days afterward. Lansoprazole administration significantly improved cisplatin-induced behavioral changes, as evidenced by decreasing the immobility time in forced swimming and open field tests. Besides, lansoprazole improved cortical histological changes, restored cortical redox balance, enhanced Nrf2/ARE expression, cisplatin-induced neuronal apoptosis, and dampened cisplatin inflammation. In addition, lansoprazole modulated cortical Akt/p53 signal. The present work was the first to show that lansoprazole co-administration reduced cortical toxicity in cisplatin-treated rats via multiple signaling pathways. The current findings provided crucial information for developing novel protective strategies to reduce cisplatin cortical toxicity.

Abstract
Methotrexate (MTX) is a chemotherapeutic agent widely used to treat a variety of tumors. Nonetheless, MTX-induced hippocampal neurotoxicity is a well-defined dose-limiting adverse effect that limits clinical utility. Proinflammatory cytokine production and oxidative stress are possible mechanisms for MTX-induced neurotoxicity. Buspirone (BSP), a partial agonist of the 5-HT1a receptor (5-HT1aR), has emerged as an anxiolytic drug. BSP has been shown to possess antioxidant and anti-inflammatory effects. The current study investigated BSP's potential anti-inflammatory and antioxidant effects in attenuating MTX-induced hippocampal toxicity. Rats received either BSP (1.5 mg/kg) orally for 10 days and MTX (20 mg/kg) i.p. on Day 5. BSP administration markedly protected hippocampal neurons from drastic degenerated neuronal changes induced by MTX. BSP significantly attenuated oxidative injury by downregulating Kelch-like ECH-associated protein 1 expression while potently elevating hippocampal Nrf2, heme oxygenase-1, and peroxisome proliferator-activated receptor expression. BSP dampened inflammation by reducing NO2 - , tumor necrosis factor-alpha, IL-6, and interleukin 1 beta levels mediated by downregulating NF-κB and neuronal nitric oxides synthase expression. Moreover, BSP potently counteracted hippocampal pyroptosis by downregulating NLRP3, ASC, and cleaved-caspase-1 proteins. Therefore, BSP may represent a promising approach to attenuate neurotoxicity in patients receiving MTX.

Abstract
Obesity involves chronic low-grade inflammation within adipose tissue. Apocynin (APO) is a therapeutic agent for the treatment of inflammatory diseases. Therefore, the present study aimed to investigate whether APO can reduce weight gain and obesity-induced adipose tissue inflammation. C57BL/6 mice were administered APO or orlistat (Orli) as a positive control with a high-fat diet (HFD) for 12 weeks. Lipopolysaccharide-stimulated 3T3-L1 adipocytes were used for the in vitro study. Our results showed a significantly lower white adipose tissue (WAT) mass index in 10 mg/kg APO-treated mice than in 20 mg/kg Orli-treated mice. Moreover, the protein expression of adipose triglyceride lipase, fatty acid synthase, sterol regulatory element-binding transcription factor 1, and peroxisome proliferator-activated receptor γ was reversed in the WAT of 10 mg/kg APO-treated mice. Furthermore, APO reduced the expression of the macrophage marker F4/80, decreased the mRNA levels of tumor necrosis factor-α and monocyte chemoattractant protein-1, and increased the mRNA levels of interleukin-10 in WAT. APO decreased the phosphorylation of c-Jun N-terminal kinase, extracellular signal-regulated kinase, and p65 in vivo and in vitro. Notably, APO had a stronger effect on the amelioration of adipose tissue inflammation than Orli did. Our findings lay the foundation for research on the use of APO as an agent to ameliorate weight gain and obesity-induced inflammatory diseases.

Abstract
Intestinal injury is a common adverse effect of methotrexate (MTX) therapy, limiting its clinical use. Despite oxidative stress and inflammation being the most embedded mechanism of injury, pharmacological agents that exhibit antioxidant and anti-inflammatory impacts could prevent such toxicities. This study aimed to assess the enteroprotective effect of lactobacillus acidophilus (LB) and/or umbelliferone (UMB) against MTX-induced intestinal injury. Histologically, pretreatment with LB, UMB, or their combinations preserve the intestinal histological structure and mucin content with superior effect in combination therapy. In addition, oral pretreatment with UMB, LB, or their combinations significantly restored oxidant/antioxidant status, as evidenced by the upregulation of Nrf2, SOD3, HO-1, GSH, and GST levels concurrent with a decline in MDA contents. Besides, they suppressed the inflammatory burden by inhibiting STAT3, MPO, TLR4, NF-κB, TNF-α, and IL-6 levels. Moreover, LB, UMB, or their combinations significantly upregulated Wnt and β-catenin expression. Notably, pretreatment with the combination therapy is superior to monotherapy in protecting rats' small intestines from MTX-induced enteritis. In conclusion, combined pretreatment with LB and UMB could be a novel therapeutic regimen for conditions of intestinal injury induced by MTX via restoring oxidant/antioxidant balance and suppressing inflammatory burden.

Edaravone alleviates methotrexate-induced testicular injury in rats: Implications on inflammation, steroidogenesis, and Akt/p53 signaling. Int Immunopharmacol 2023; 117:109969. [PMID: 37012866 DOI: 10.1016/j.intimp.2023.109969] [Citation(s) in RCA: 2] [Impact Index Per Article: 2.0] [Reference Citation Analysis] [Abstract] [Track Full Text] [Journal Information] [Subscribe] [Scholar Register] [Received: 01/04/2023] [Revised: 02/21/2023] [Accepted: 02/27/2023] [Indexed: 03/11/2023]
Abstract
Edaravone (ED) is a neuroprotective drug with beneficial effects against several disorders due to its prominent antioxidant activity. However, its effect against methotrexate (MTX)-induced testicular damage was not previously investigated. Therefore, we aimed to investigate the ability of ED to prevent the oxidative stress, inflammation, and apoptosis induced by MTX on the rat testis and to examine whether ED administration modulated the Akt/p53 signaling and steroidogenesis process. Rats were allocated into; Normal, ED (20 mg/kg, PO, for 10 days), MTX (20 mg/kg, i.p., on the 5th day), and ED + MTX groups. The results showed that MTX group exhibited higher serum activities of ALT, AST, ALP, and LDH in addition to histopathological alterations in the rat testis, compared to normal group. Furthermore, MTX induced down-regulation of the steroidogenic genes; StAR, CYP11a1, and HSD17B3 and reduced FSH, LH, and testosterone levels. The MTX group also showed higher levels of MDA, NO, MPO, NF-kB, TNF-α, IL-6, IL-1β, Bax, and caspase 3, as well as, lower levels of GSH, GPx, SOD, IL-10, Bcl2 compared to normal rats, p < 0.05. In addition, MTX treatment resulted in increased p53 expression and decreased p-Akt expression. Remarkably, ED administration significantly prevented all the biochemical, genetic, and histological damage induced by MTX. Hence, ED treatment protected the rat testis from apoptosis, oxidative stress, inflammation, and impaired steroidogenesis induced by MTX. This novel protective effect was mediated by decreasing p53 while increasing p-Akt protein expression.

Abstract
Cardiac toxicity is a public health issue that can be caused by both environmental and occupational exposures. The current study aimed to investigate the effectiveness of carvedilol (CV), Acetovanillone (ACET), and their combination for ameliorating cadmium (Cd)-induced oxidative stress, inflammation, and necroptosis. Rats were assigned to; the normal group, Cd group (2 mg/kg; i.p., single dose), and the other three groups received orally CV (10 mg/kg), ACET (25 mg/kg), and CV plus ACET, respectively and a single dose of Cd. Oral administration of CV, ACET, and their combination significantly dampens cardiac oxidative injury by increasing antioxidants GSH and SOD levels, while it decreases MDA and NADPH oxidase levels mediated by decreasing cardiac abundance of Nrf2, HO-1, and SIRT1 and downregulating KEAP-1 and FOXO-3 levels. Also, they significantly attenuated inflammatory response as indicated by reducing MPO and NOx as well as proinflammatory cytokines TNF-α and IL-6 mediated by downregulating TLR4, iNOS, and NF-κB proteins expression as well as IκB upregulation. Moreover, they potently counteracted cardiac necroptosis by downregulating RIPK1, RIPK3, MLKL, and caspase-8 proteins expression. Of note, the combination of CV and ACET have marked protection that exceeded each drug alone. Conclusively, CV ad ACET potently mitigated Cd-induced cardiac intoxication by regulating NADPH oxidase, KEAP-1/Nrf2/HO-1, SIRT1/FOXO-3, TLR4/NF-κB/iNOS, and RIPK1/RIPK3/MLKL signals.

Abstract
Cisplatin (CDDP) is an effective chemotherapeutic drug that has been used successfully in treating various tumors. Although its higher antineoplastic agent activity, CDDP exhibited severe side effects that limit its use. CDDP-induced toxicity is attributed to oxidative stress and inflammation. Apocynin (APO) is a bioactive phytochemical with potent antioxidant and anti-inflammatory properties. However, pharmaceutical experts face significant hurdles due to the limited bioavailability and quick elimination of APO. Therefore, we synthesized a chitosan (CTS)-based nano delivery system using the ionic gelation method to enhance APO bioactivity. CTS-APO-NPs were characterized using different physical and chemical approaches, including FTIR, XRD, TGA, Zeta-sizer, SEM, and TEM. In addition, the protective effect of CTS-APO-NPs against CDDP-induced nephrotoxicity, hepatotoxicity, and cardiotoxicity in rats was evaluated. CTS-APO-NPs restored serum biomarkers and antioxidants to their normal levels. Also, histopathological examination was used to assess the recovery of heart, kidney, and liver tissues. CTS-APO-NPs attenuated the oxidative stress mediated by Nrf2 activation while it dampened inflammation mediated by NF-κB suppression. CTS-APO-NPs is a potentially attractive target for more therapeutic trials.

Abstract
Ovarian ischemia-reperfusion (I-R) injury may damage remote organs, including the lungs. We investigated whether apocynin, a NADPH oxidase inhibitor, might protect against ovarian I-R induced apoptosis in the lungs of rats. Bilateral ovarian I-R was induced for 3 h, then apocynin was applied at two concentrations. Lung tissue was evaluated using spectrophotometric and immunohistochemical methods. We found that I-R increased total oxidant status (TOS), oxidative stress index (OSI) and myeloperoxidase (MPO) levels, and immunostaining of nuclear factor kappa-B (NF-κB), light chain 3B (LC3B), interleukin 1-beta (IL-1β), caspase-3 and tumor necrosis factor-alpha (TNF-α), but decreased superoxide dismutase (SOD) values. Apocynin application to I-R injured rats enhanced recovery of lung tissue oxidants and improved both histology and frequency of apoptosis.

Abstract
Leydig cells are responsible for testosterone production in male testis upon stimulation by luteinizing hormone. Inflammation and oxidative stress related Leydig cell dysfunction is one of the major causes of male infertility. Cytoglobin (CYGB) and Neuroglobin (NGB) are two globin family member proteins which protect cells against oxidative stress. In the current study, we established a Lipopolysaccharide (LPS)-induced inflammation model in TM3 Leydig cell culture to study the function of CYGB and NGB proteins under inflammatory conditions. CYGB and NGB were downregulated using siRNA and shRNA based experimental strategies. Overexpression was conducted using lentiviral pLenti-III-CYGB-2A-GFP, and pLenti-III-NGB-2A-GFP vector systems. As testicular macrophages regulate immune function upon inflammation and steroidogenesis of Leydig cells, we generated direct/indirect co-culture systems of TM3 and mouse macrophage (RAW264.7) cells ex vivo. Downregulation of CYGB and NGB induced nitride oxide (NO) release, blocked cell cycle progression, reduced testosterone production and increased inflammatory and apoptotic pathway gene expression in the presence and absence of LPS. On the other hand, CYGB and NGB overexpression reduced TNFα and COX-2 protein expressions and increased the expression of testosterone biogenesis pathway genes upon LPS stimulation. In addition, CYGB and NGB overexpression upregulated testosterone production. The present study successfully established an inflammatory interaction model of TM3 and RAW264.7 cells. Suppression of CYGB and NGB in TM3 cells changed macrophage morphology, enhanced macrophage cell number and NO release in co-culture experiments upon LPS exposure. In summary, these results demonstrate that globin family members might control LPS induced inflammation by regulating apoptotic mechanisms and macrophage response.

Abstract
Methotrexate (MTX) is commonly used as a therapeutic agent in the treatment of malignancies and autoimmune disorders. Risk of subsequent infertility following MTX administration has been reported as a significant side effect due to testicular toxicity. The aim of the study was to evaluate the modulatory effects of Ginkgo biloba (standardized extract, EGb 761) on MTX-induced testicular oxidative stress, energy deficits and spermatogenic status in rats. All groups received intraperitoneal injection of MTX (0.5 mg/kg) twice weekly for four weeks except the control group that received the corresponding vehicles. Other groups received oral EGb761, at doses 25, 50 or 100 mg/kg/day, for four weeks, concurrently with MTX. Blood and semen sampling followed by testis dissection were performed 24 h after last EGb 761 treatment. Semen was examined for sperm progressive motility, percent of normal spermatozoa and sperm cell concentration as well as seminal plasma essential and non-essential amino acids. Serum LH, FSH and testosterone were detected as well as testicular MDA, GSH, GSSG, TNF-α, IL-1β, IL-6, NF-κB and the nuclear, cytoplasmic and mRNA expression levels of Nrf-2 besides the testicular cell energy; AMP, ADP and ATP. Histopathological studies of interstitial fibrosis and the severity of germ cell degeneration were also conducted. MTX induced significant decline in sperm quality along with decreased essential and non-essential amino acids in seminal plasma. MTX reduced serum FSH, LH and testosterone as well as testicular ATP, GSH and Nrf2, while increased levels of testicular ADP, AMP, MDA, GSSG and TNF-α. Results were confirmed by prominent interstitial fibrosis and severe germ cell degeneration in MTX group. Concurrent treatment with EGb 761 alleviated MTX-induced testicular insult evidenced by amelioration of oxidative stress biomarkers, energy functions, seminal sperms abnormalities and spermatogenesis status. The present study suggests a beneficial role of EGb 761 in MTX-induced testicular injury and subsequent distortion of spermatogenesis.
