Alleviation of Liver Dysfunction, Oxidative Stress and Inflammation Underlies the Protective Effect of Ferulic Acid in Methotrexate-Induced Hepatotoxicity. DRUG DESIGN DEVELOPMENT AND THERAPY 2020; 14:1933-1941. [PMID: 32546960 PMCID: PMC7250701 DOI: 10.2147/dddt.s237107] [Citation(s) in RCA: 35] [Impact Index Per Article: 8.8] [Reference Citation Analysis] [Abstract] [Key Words] [Track Full Text] [Download PDF] [Figures] [Subscribe] [Scholar Register] [Received: 11/02/2019] [Accepted: 04/27/2020] [Indexed: 01/11/2023]
Abstract
Introduction In multiple studies, involvement of oxidative stress in the pathogenesis of methotrexate (MTX)-mediated liver damage has been confirmed. Use of many drugs has been examined experimentally in order to prevent or diminish oxidative stress. However, no study has yet examined the effects of ferulic acid (FA) on MTX-induced liver damage. This study aimed at evaluating the effects of FA on protection against liver damage induced by MTX in mice. Materials and Methods In this the mice were divided into five groups in a random manner: I) control; II) MTX (20 mg/kg); III and IV) FA (50 and 100 mg/kg) + MTX; and V) FA (100 mg/kg), and we measured serum factors, oxidative stress and inflammatory factors. Results In the MTX group, accumulation of inflammatory cells, accumulation of red blood cell (RBC), and nuclear pyknosis (NP) were detected in the liver. In line with the histological data, the levels of nitric oxide (NO), malondialdehyde (MDA), interleukin-6 (IL-6), and tumor necrosis factor-α increased (TNF-α), whereas the reduced glutathione (GSH), catalase (CAT), total antioxidant capacity (TAC), superoxide dismutase (SOD), and glutathione peroxidase (GPx) content reduced in the MTX group. However, FA ameliorated these hazardous effects in the antioxidant and anti-inflammatory systems in MTX-treated groups. Conclusion Based on our findings, oxidative stress impairment and MTX-induced liver damage were ameliorated following FA pretreatment at both histological and biochemical levels. Therefore, FA can be effectively used in abrogation of MTX-induced toxicity.

Abstract
Pretubulysin (PT), a potent tubulin-binding antitumoral drug, and the well-established antimetabolite methotrexate (MTX) were tested separately or in combination (PT+MTX) for antitumoral activity in L1210 leukemia cells or KB cervix carcinoma cells in vitro and in vivo in NMRI-nu/nu tumor mouse models. In cultured L1210 cells, treatment with PT or MTX displays strong antitumoral effects in vitro, and the combination PT+MTX exceeds the effect of single drugs. PT also potently kills the MTX resistant KB cell line, without significant MTX combination effect. Cell cycle analysis reveals the expected arrest in G1/S by MTX and in G2/M by PT. In both cell lines, the PT+MTX combination induces a G2/M arrest which is stronger than the PT-triggered G2/M arrest. PT+MTX does not change rates of apoptotic L1210 or KB cells as compared to single drug applications. Confocal laser scanning microscopy images show the microtubule disruption and nuclear fragmentation induced by PT treatment of L1210 and KB cells. MTX changes the architecture of the F-actin skeleton. PT+MTX combines the toxic effects of both drugs. In the in vivo setting, the antitumoral activity of drugs differs from their in vitro cytotoxicity, but their combination effects are more pronounced. MTX on its own does not display significant antitumoral activity, whereas PT reduces tumor growth in both L1210 and KB in vivo models. Consistent with the cell cycle effects, MTX combined at moderate dose boosts the antitumoral effect of PT in both in vivo tumor models. Therefore, the PT+MTX combination may present a promising therapeutic approach for different types of cancer.

Abstract
The new generation of nanoparticles (NPs) encompass attributes of lipids and polymers and are referred to as 'lipid-polymer hybrid nanoparticles' (LPHNPs). LPHNPs have helped shed light on the mechanisms involved in targeted and non-specific drug delivery. Research has also highlighted the opportunities and challenges faced by the use of nanomedicine as personalized therapies in oncology. Here, we review the development of LPHNPs as cancer therapeutics, focusing on the methods deployed for enhancing the targeting efficiency and applications of LPHNPs.

Abstract
Methotrexate (MTX) is effective therapeutic agent treated many tumors and autoimmune diseases. The aim of our study was to design an effective delivery nanocarrier for methotrexate to improve stability and biodistribution, reduce adverse effects and maximize clinical efficacy. Magnetite nanoparticles (Fe3O4-NPs) were synthesized using Pterocladiella. The size of Fe3O4-NPs, CS-Fe3O4-NPs and MTX/CS-Fe3O4-NPs were 37.6, 61.4 and 150 nm respectively. Methotrexate loading efficiency was 74.15% of total amount of MTX loaded on CS-Fe3O4-NPs and 39.8% of the loaded drug was initially released and the remaining amount was released through 120 h. The IC50 of MTX and MTX/CS-Fe3O4-NPs was 51.4 and 9.7 μg/ml respectively after 72 h. MTX/CS-Fe3O4-NPs caused remarkable damage to the membrane of MCF-7 cells led to increasing the LDH activity 5 fold in MCF-7 cells as compared with MTX treated once. DNA fragmentation and caspase-3 activity were higher in MCF-7 cells treated with MTX/CS-Fe3O4-NPs than that of MTX. Up-regulation of caspase3 and DHFR genes expression was observed in the treatment with MTX/CS-Fe3O4-NPs. The loading of MTX on chitosan coated Fe3O4-NPs improves the release and anticancer efficacy of MTX for effective cancer treatment.

Abstract
Side effects of methotrexate (MTX) especially hepatotoxicity limits clinical applications of this anticancer agent. Carboxypeptidase G2 (CPG2) is administrated for the treatment of elevated plasma concentrations of MTX. In this study, we have investigated the intracellular delivery of CPG2 fused to the transactivator transduction domain (TAT) and its protective effects against MTX-induced cell death of HepG2 cells. We have observed that both native and denatured forms of the enzyme transduced into the HepG2 cells efficiently in a concentration and time-dependent manner. The denatured protein transduced with higher efficiency than the native form and was functional inside the cells. MTX exposure significantly decreased HepG2 cell viability in a dose- and time-dependent manner. The cell viability after 24 and 48 h of incubation with 100 μM MTX was reduced to 44.37% and 17.69%, respectively. In cells pretreated with native and denatured TAT-CPG2 protein the cell viability was 98.63% and 86.31% after 24 and 48 h, respectively. Treatment with MTX increased the number of apoptotic HepG2 cells to 90.23% after 48 h. However, the apoptosis percentage in cells pretreated with native and denatured TAT-CPG2 was 21.49% and 22.28%, respectively. Our results showed that TAT-CPG2 significantly prevents MTX-induced oxidative stress by decreasing the formation of ROS and increasing the content of glutathione (GSH) and catalase activity. Our finding indicates that both native and denatured TAT-CPG2 strongly protect HepG2 cells against MTX-induced oxidative stress and apoptosis. Hence, intracellular delivery of CPG2 might provide a new therapeutic strategy for protecting against MTX mediated cytotoxicity.

Abstract
OBJECTIVE The aim of the study was to compare the natural menopause ages of healthy women with those of women with methotrexate (MTX)-treated rheumatoid arthritis (RA), and to specifically assess the effect of disease onset and activity and the use of MTX on the age of the last menstruation. METHODS We performed a retrospective review of medical records to identify the ages at which menopause occurred in women with premenopausal RA treated with MTX and in women with postmenopausal onset, irrespective of therapy. Natural menopause ages were also compared between participants with and without RA. RESULTS Women with premenopausal onset of RA underwent menopause at a significantly younger age than did healthy women (P < 0.001) or those with postmenopausal disease onset (P = 0.001). Menopause also occurred at younger ages in participants with postmenopausal disease onset than in healthy controls (P = 0.012). The study suggested that menopause age was positively correlated with the age at which RA was diagnosed (R = 0.51; P < 0.001) in women with premenopausal RA onset, but was independent of the participant's age at menarche, number of pregnancies, or MTX therapy. Participants with RA onset at ≤ 35 years of age had a ninefold higher risk of premature menopause (P = 0.008). CONCLUSIONS The age at which menopause occurs in a patient with RA depends on the patient's age at the time of disease onset and its duration, but is not influenced by MTX treatment.

Abstract
Gestational Trophoblastic Neoplasia (GTN) is a term used for a group of malignant gynecological tumors including choriocarcinoma. Low-risk neoplasias can be cured using single agents Methotrexate (MTX) and actinomycin-D (ACD), but in certain cases, decreased responsiveness and serious side effects occur. Therefore, researchers have been attempting to find new treatment modalities. One of the most popular way for increasing cancer patient survival rates is supporting treatment with adjuvant molecules or chemosensitizers. For this purpose, we investigated epigallocatechin-3-gallate (EGCG), a green tea cathecin, and Erlotinib, an EGFR tyrosine kinase inhibitor, as single agents and combined with MTX or ACD. In accordance with this, JAR (human placenta choriocarcinoma) cell line was used as an in vitro model and MTT, LDH, caspase-3 activation, RT-PCR, and Western Blot analyses were performed to investigate the effects of the test materials. Our studies demonstrate that combination of Erlotinib and EGCG with MTX and ACD decreases JAR cell proliferation and metastatic HER2 protein synthesis and increases caspase-3 activation compared to ACD or MTX alone. In addition, significant increase was observed in the apoptotic Bax gene, but no notable protein synthesis occurred in the Western Blot analysis, which suggests that combination of Erlotinib and EGCG with classical chemotherapeutics ACD or MTX may lead the JAR cells to apoptosis, but not by a mitochondrial pathway. All the results indicate that the synergetic effect of Erlotinib and EGCG with classical chemotherapeutics may help to increase patient survival rates of choriocarcinoma, but the detailed mechanism needs further investigation.

Abstract
The present study was designed to engineer surface-anchored and methotrexate loaded lipobrid nano-constructs for targeting breast cancer. Ligands (fucose, galactose and mannose) anchored lipobrid nano-constructs were used to compare and assess delivery efficiency in breast cancer cell lines as well as in DMBA induced breast cancer animal model. The developed and characterized formulations were used to comparatively assess cellular uptake, cell-viability, apoptosis, lysosomal membrane permeability, bioavailability, bio-distribution, changes in tumor volume and animal survival. Our results show greater cellular uptake, cytotoxicity at low IC50, apoptosis with altered lysosomal membrane permeability and greater rate of degradation of lysosomal membrane. We saw better bioavailability and tumor targeting efficiency with minimum secondary organ drug distribution. The significant reduction was seen in tumor burden with ligand anchored lipobrids in comparison to plain and MTX-lipobrid formulations. In conclusion, fucose anchored MTX-lipobrid formulation showed promising results, and warrants to explore the development of therapeutic interventions for breast cancer.

Abstract
Oridonin is one of the most important antitumor active ingredients of Rabdosia rubescens. Recently published studies from our laboratory have demonstrated that oridonin was able to arrest human gastric cancer SGC-7901 cells at G2/M phase. However, little is known about inducing apoptosis in gastric cancer. The aim of this study was to investigate the effect of oridonin on antineoplastic capability of SGC-7901 cells and the detailed molecular mechanism of oridonin-mediated intrinsic pathway of apoptosis. Cell proliferation was assessed by MTT assay while apoptosis induced by oridonin was determined by Hoechst 33342 staining assay and Annexin V/PI double staining assay. Early apoptotic rate was stained by Annexin V/PI and detected by flow cytometry. Apoptosis pathway was analyzed by western blot analysis of Bcl-2, Bax, cytochrome c and caspase-3 expression. The results showed that oridonin was able to inhibit the SGC-7901 cell proliferation, the 50% growth inhibition (IC50) was 22.74 µM. Oridonin could induce cell apoptosis of SGC-7901 cells and the early apoptotic rates induced by 0, 20, 40, 80 µmol/l oridonin were 1.53±0.67, 3.33±0.29, 84.80±0.82 and 96.43±0.51%, respectively. Western blot analysis revealed that oridonin downregulated Bcl-2 protein (the anti-apoptotic factor) and upregulated Bax protein (pro-apoptotic factor), eventually leading to a reduction in the ratio of Bcl-2/Bax proteins. Furthermore, oridonin induced the release of cytochrome c from the mitochondria to the cytosol and the activation of caspase-3. Taken together, the current study suggested that oridonin induced apoptosis in SGC-7901 cells via the mitochondrial signal pathway, which may represent one of the major mechanisms of oridonin-mediated apoptosis in SGC-7901 cells.

Abstract
Objectives Propolis is a potent antioxidant and a free radical scavenger. Pharmacological induction of heat shock proteins (HSPs) has been investigated for restoring normal cellular function following an injury. In this study, effect of propolis on HSP-70 expression in methotrexate-induced nephrotoxicity and direct preventive effect of propolis in this toxicity were investigated. Material and methods A total of 40 male Wistar albino rats were divided into four groups: Group 1 was the untreated control. On the eighth day of the experiment, groups 2 and 3 received single intraperitoneal injections of methotrexate (MTX) at 20 mg/kg. Groups 3 and 4 received 100 mg/kg/day propolis (by oral gavage) for 15 d by the first day of the experimental protocol. Then the rats were decapitated under ketamine esthesia and their kidney tissues were removed. HSP-70 expression, apoptosis, and histopathological damage scores were then compared. Results MTX caused epithelial desquamation into the lumen of the tubules, dilatation, and congestion of the peritubular vessels and renal corpuscles with obscure Bowman's space. The number of apoptotic cells (p = 0.000) and HSP-70 (p = 0.002) expression were increased in group 2. Propolis prevented the rise in number of apoptotic cells (p = 0.017), HSP-70 (p = 0.000) expression, and improved kidney morphology. Conclusions It was found that methotrexate gives rise to serious damage in the kidney and propolis is a potent antioxidant agent in preventing kidney injury.

Abstract
Methotrexate (MTX), a folic acid antagonist, an effective chemotherapeutic agent is used in the treatment of a wide range of tumors and autoimmune diseases. Moreover, hepatotoxicity limits its clinical use. Several studies have already confirmed that the oxidative stress plays a major role in the pathogenesis of MTX-induced damage in the various organs especially in liver. The aim of this study was to determine the protective effect of Chrysin against MTX-induced hepatic oxidative stress and apoptosis in rats. In the present study, efficacy of Chrysin was investigated against hepatotoxicity caused by MTX in terms of biochemical investigations of antioxidant enzymes, apoptosis, and histopathological alteration in rat liver. In the MTX-treated group there was a significant increase in alanine transaminase, aspartate aminotransferase, lactate dehydrogenase activity and malondialdehyde content as well as decreased glutathione peroxidase, glutathione reductase, superoxide dismutase, catalase activities and reduced glutathione content were also observed compared to the control group as a marker of oxidative stress. Histopathological alterations and apoptosis through the immunopositive staining of p53, cleaved caspases-3 and Bcl-2-associated X protein in rat liver were observed. Pretreatment of Chrysin at both doses prevents the hepatotoxicity by ameliorating oxidative stress, histopathological alterations, and apoptosis and thus our results suggest that Chrysin has a protective effect against hepatotoxicity induced by MTX and it may, therefore, improve the therapeutic index of MTX if co-administration is done.

Abstract
Methotrexate (MTX) widely used in the treatments of various types of malignancies, but high toxicity and short plasma half-life have limited its use. This study was aimed at developing a polymeric drug delivery system for improving the therapeutic index of this potent drug. To achieve these goals, PLGA and PLGA-PEG nanoparticles were prepared using the emulsification-solvent diffusion technique and were optimized for particle size and entrapment efficiency. The optimum loaded nanoparticles were evaluated by cytotoxicity and their ability to induce apoptosis compared to free drug by examining of caspase-3 activity. The results showed that optimized particles were 182 ± 14 nm and 258 ± 10 nm in size for PLGA-PEG and PLGA nanoparticles, respectively, with an entrapment efficiency of more than 51%. The cytotoxicity experiment showed that the nanoparticles were more effective than pure MTX and increase the activity of caspase-3 in MCF7 and AGS and A549 cell lines.

Abstract
This study was conducted to evaluate a possible protective role of apricot in apoptotic cell death induced by methotrexate (MTX) and renal damage by different histological and biochemical parameters. Twenty-eight rats were divided into four groups, control, apricot, methotrexate, and apricot + methotrexate. Methotrexate induced renal failure, as shown by significant serum creatinine and urea elevation. Additionally, the results indicated that methotrexate significantly induced lipid peroxidation and reduced antioxidant activities in rats. In contrast, apricot significantly prevented toxic effects of methotrexate via increased catalase, superoxide dismutase, and glutathione levels but decreased formation of malondialdehyde. Also, it was determined that exposure to methotrexate leads to significant histological damage in kidney tissue such as glomerulosclerosis and apoptosis. On the other hand, these effects can be eliminated with apricot diet. These data indicate that apricot may be useful in preventing undesirable effects of MTX such as nephrotoxicity.

Abstract
Human leukocyte antigen (HLA)-G is a class I non-classical HLA molecule with an important regulatory role on the immune response. The possible role of this molecule in the pathogenesis of SLE has not been explored. In this work, we evaluated the expression and function of HLA-G in SLE patients. We studied 37 SLE patients as well as 25 healthy donors. Peripheral blood monocytes and in vitro-generated dendritic cells (DCs) were analyzed for HLA-G expression by flow cytometry. We found that monocytes from SLE patients as well as mature CD83+ DCs showed a diminished expression of HLA-G compared with healthy controls. In addition, monocytes from SLE patients showed a diminished induction of HLA-G expression in response to stimulation with IL-10. Furthermore, functional assays showed that these monocytes pre-treated with IFN-γ exhibited a diminished capability to inhibit the proliferation of autologous lymphocytes. Finally, lymphocytes from SLE patients tended to display a lower acquisition of HLA-G (by trogocytosis) from autologous monocytes compared to controls. Our results might have implications for the immune abnormalities observed in patients with SLE.

Abstract
Imatinib mesylate (STI571) is the first member of a new class of agents that act by inhibiting specific tyrosine kinases, rather than killing all rapidly dividing cells. This drug is usually used in the treatment of chronic myelogenous leukemia and gastrointestinal stromal tumors. It was recognized to inhibit activity of kinases such as Bcr/Abl, platelet-derived growth factor receptor, and c-kit. These proteins play important roles in cell growth, motility, and survival. Therefore, studies on the biological effects of imatinib on different cellular models are very important. Human colon adenocarcinoma LS180 cell line was used in the studies presented. Cells were exposed to 0.1-100 μM imatinib for 24 and 48 h. Dose-dependent decreases in cell viability and morphological changes were observed. Moreover, the apoptotic effect of imatinib (10 μM, 50 μM) after 24 h of exposure was demonstrated as evaluated by translocation of phosphatidylserine to external membrane leaflet and by increased activity of caspase-3. Special attention was focused on imatinib influence on actin cytoskeleton organization and migration ability of LS180 cells. Distinct alterations in actin cytoskeleton architecture occurred in response to drug treatment, accompanied by appearance of filamentous actin aggregates and decrease in actin polymerization state. These changes were correlated with remarkable decrease in cell migration capacity. In summary, our data clearly demonstrate that imatinib induces apoptosis and inhibits human colon adenocarcinoma cell migration. Therefore, this drug may have potential in colon cancer therapy in the future.

Abstract
During apoptosis, a number of physical changes occur in the cell membrane including a gradual increase in permeability to vital stains such as propidium iodide. This study explored the possibility that one consequence of membrane changes concurrent with early modest permeability is vulnerability to degradation by secretory phospholipase A(2). The activity of this hydrolytic enzyme toward mammalian cells depends on the health of the cell; healthy cells are resistant, but they become susceptible early during programmed death. Populations of S49 lymphoma cells during programmed death were classified by flow cytometry based on permeability to propidium iodide and susceptibility to secretory phospholipase A(2). The apoptotic inducers thapsigargin and dexamethasone caused modest permeability to propidium iodide and increased staining by merocyanine 540, a dye sensitive to membrane perturbations. Various secretory phospholipase A(2) isozymes (human groups IIa, V, X, and snake venom) preferentially hydrolyzed the membranes of cells that displayed enhanced permeability. In contrast, cells exposed briefly to a calcium ionophore showed the increase in cell staining intensity by merocyanine 540 without accompanying uptake of propidium iodide. Under that condition, only the snake venom and human group X enzymes hydrolyzed cells that were dying. These results suggested that cells showing modest permeability to propidium iodide during the early phase of apoptosis are substrates for secretory phospholipase A(2) and that specificity among isoforms of the enzyme depends on the degree to which the membrane has been perturbed during the death process. This susceptibility to hydrolysis may be important as part of the signal to attract macrophages toward apoptotic cells.
