Abstract
BACKGROUND It is necessary to develop advanced therapies utilizing natural ingredients with anti-inflammatory qualities in order to lessen the negative effects of chemotherapeutics. RESULTS The bioactive N1-(5-methyl-5H-indolo[2,3-b]quinolin-11-yl)benzene-1,4-diamine hydrochloride (NIQBD) was synthesized. After that, soluble starch nanoparticles (StNPs) was used as a carrier for the synthesized NIQBD with different concentrations (50 mg, 100 mg, and 200 mg). The obtained StNPs loaded with different concentrations of NIQBD were coded as StNPs-1, StNPs-2, and StNPs-3. It was observed that, StNPs-1, StNPs-2, and StNPs-3 exhibited an average size of 246, 300, and 328 nm, respectively. Additionally, they also formed with homogeneity particles as depicted from polydispersity index values (PDI). The PDI values of StNPs-1, StNPs-2, and StNPs-3 are 0.298, 0.177, and 0.262, respectively. In vivo investigation of the potential properties of the different concentrations of StNPs loaded with NIQBD against MTX-induced inflammation in the lung and liver showed a statistically substantial increase in levels of reduced glutathione (GSH) accompanied by a significant decrease in levels of oxidants such as malondialdehyde (MDA), nitric oxide (NO), advanced oxidation protein product (AOPP), matrix metalloproteinase 9/Gelatinase B (MMP-9), and levels of inflammatory mediators including interleukin 1-beta (IL-1β), nuclear factor kappa-B (NF-κB) in both lung and liver tissues, and a significant decrease in levels of plasma homocysteine (Hcy) compared to the MTX-induced inflammation group. The highly significant results were obtained by treatment with a concentration of 200 mg/mL. Histopathological examination supported these results, where treatment showed minimal inflammatory infiltration and congestion in lung tissue, a mildly congested central vein, and mild activation of Kupffer cells in liver tissues. CONCLUSION Combining the treatment of MTX with natural antioxidant supplements may help reducing the associated oxidation and inflammation.

Abstract
While oncotherapy has made rapid progress in recent years, side effects of anti-cancer drugs and treatments have also come to the fore. These side effects include cardiotoxicity, which can cause irreversible cardiac damages with long-term morbidity and mortality. Despite the continuous in-depth research on anti-cancer drugs, an improved knowledge of the underlying mechanisms of cardiotoxicity are necessary for early detection and management of cardiac risk. Although most reviews focus on the cardiotoxic effect of a specific individual chemotherapeutic agent, the aim of our review is to provide comprehensive insight into various agents that induced cardiotoxicity and their underlying mechanisms. Characterization of these mechanisms are underpinned by research on animal models and clinical studies. In order to gain insight into these complex mechanisms, we emphasize the role of inflammatory processes and oxidative stress on chemotherapy-induced cardiac changes. A better understanding and identification of the interplay between chemotherapy and inflammatory/oxidative processes hold some promise to prevent or at least mitigate cardiotoxicity-associated morbidity and mortality among cancer survivors.

Abstract
Psoriasis is an immune-mediated, chronic disorder that significantly alters patients' quality of life and predisposes them to a higher risk of comorbidities, including liver fibrosis. Various non-invasive tests (NITs) have been validated to assess liver fibrosis severity, while blood-count-derived inflammatory markers have been proven to be reliable in reflecting inflammatory status in psoriatic disease. The fibrosis-4 (FIB-4) index became part of the newest guideline for monitoring psoriasis patients undergoing systemic treatment. Patients with psoriasis vulgaris and fulfilling inclusion criteria were enrolled in this study, aiming to assess for the first time in the literature whether such inflammatory markers are useful in predicting liver fibrosis. Based on internationally validated FIB-4 index values, patients were divided into two study groups: a low risk of significant fibrosis (LR-SF) and a high risk of significant fibrosis (HR-SF). Patients from HR-SF were significantly older and had higher values of the monocyte-to-lymphocyte ratio (MLR) (p < 0.001), which further significantly correlated with fibrosis severity (p < 0.001). Platelet-to-lymphocyte ratio (PLR), systemic immune inflammation index (SII), platelet-to-white blood cell ratio (PWR), and aggregate index of systemic inflammations (AISI) significantly correlated negatively with liver fibrosis (p < 0.001). PWR proved to be the most reliable inflammatory predictor of fibrosis severity (AUC = 0.657). MLR, PWR, and AISI were independent inflammatory markers in multivariate analysis (p < 0.001), while the AST to platelet ratio index (APRI) and AST to ALT ratio (AAR) can be used as additional NITs for significant liver fibrosis (p < 0.001). In limited-resources settings, blood-count-derived inflammatory markers such as MLR, PWR, and AISI, respectively, and hepatic indexes APRI and AAR prove to be of particular help in predicting significant liver fibrosis.

Abstract
Psoriasis is a chronic inflammatory disease, with a major impact on the patients' quality of life. Oxidative stress (OS) is represented by the imbalance between oxidant and antioxidant mechanisms of the organism, with increased levels being described in the majority of chronic diseases. We present the first prospective study in Romania to evaluate the redox balance changes (using a CR3000 analyzer) in patients with moderate-severe psoriasis based on treatment regimens: treatment-naïve (A), treatment with novel targeted agents (B) and methotrexate (C). The study group included 53 Caucasian patients divided into three groups (A- 27 patients, B - 15 patients, and C - 11 patients) for which OS, antioxidant status, standard blood count, and inflammatory status were evaluated. Our findings demonstrate that patients with psoriasis display high levels of OS, with elevated Free Oxygen Radical Test (FORT) (p-value for group A (pA)<0.0001, p-value for group B (pB)=0.0019 and p-value for group C (pC)=0.0063) and reduced Free Oxygen Radical Defense (FORD) (pB=0.018) values noted in our subjects. Higher erythrocyte sedimentation rate (ESR) values were detected in groups B (pB=0.00012) and C (pC<0.00001). Psoriasis treatments alleviate FORT and FORD levels, but their impact is not sufficient to restore the oxidative balance to normal ranges. Moreover, despite adequate treatment, patients with psoriasis display elevated inflammation levels. Future research should explore in more detail the interplay between OS and inflammation in psoriasis, namely the long-term impact on the redox balance of biotherapies.

Abstract
Methotrexate (MTX) is an antineoplastic and anti-inflammatory agent, which is used in severe diseases. Its use should be limited due to side effects such as nephrotoxicity, myelotoxicity, and hepatotoxicity. Nebivolol (NBV), which is a beta-blocker used in the treatment of hypertension, also contributes to vasodilation in tissues by activating the endothelial nitric oxide synthase (eNOS) enzyme. The purpose of this study is to research the effect of NBV on MTX-induced nephrotoxicity through the AKT1/hypoxia-inducible factor 1-alpha (Hif-1α)/eNOS signaling pathway. The rats were randomly divided into three groups of eight each. The groups were control, MTX, and MTX + NBV. A single dose of 20 mg/kg MTX was given intraperitoneally to the rats on the first day of the study and 10 mg/kg NBV was given orally to the treatment group for 7 days. At the end of the study, rats' blood and kidney tissues were taken for histopathological, immunohistochemical, and biochemical examinations. MTX administration significantly decreased the expression levels of AKT1, eNOS, and Hif-1α compared with the control group (p < 0.001 for all), and NBV treatment increased these values compared with the MTX group (p < 0.001 for all). In conclusion, NBV treatment ameliorated the MTX-induced nephrotoxicity via AKT1/Hif-1α/eNOS signaling pathway.

Abstract
OBJECTIVE To evaluate the protective role of nanocurcumin on the toxicity induced by methotrexate in the submandibular glands of rats. DESIGN Twenty- four healthy male Wistar albino rats were randomly distributed into 3 groups, 8 rats each. Group I-control: rats received a single intraperitoneal injection of saline; Group II-methotrexate (MTX): rats received methotrexate 20 mg/ kg day 1 of the experiment; Group III-methotrexate and nanocurcumin (MTX+NCU): rats received methotrexate 20 mg/ kg on day 1 of the experimental period in addition to nanocurcumin 100 mg/kg/day for 7 days. After euthanasia, the submandibular salivary glands of all rats were collected and prepared for histological, histomorphometric, and immunohistochemical examination (Caspase 3, Bcl2), in addition to transmission electron microscopy. RESULTS Histological and ultrastructural assessment revealed less salivary gland damage in the nanocurcumin group in comparison to the methotrexate group, and the percentage of acinar vacuolization showed significantly lower values in the nanocurcumin group. Group III (MTX+NCU) showed lower immunoexpression of caspase 3 than group II (MTX), while Bcl2 immunoreactivity was higher in the MTX group than in the MTX+NCU group. CONCLUSIONS Our results suggest that simultaneous administration of nanocurcumin reduces apoptosis in salivary glands subjected to methotrexate.

Abstract
Objective Grape Seed Extract is a natural source of various polyphenols, which have been shown to possess potent antioxidant and free radical-scavenging activities. The earlier studies have reported that grape seed extract exhibits broad-spectrum pharmacological activities. Therefore, studying the hepatoprotective effects and elucidation of mechanisms of action of the Indian Variety, Manjari Medika grape seed extract (GSE), may give an insight into therapeutic benefits. Methotrexate (MTX) is the first-line pharmacological therapy for different rheumatic diseases. The major adverse events such as hepatotoxicity are evident even in the low doses used for the treatment. The present study investigated the role of MTX on hepatic damage in murine liver and the plausible protective effects of the Indian grape variety, Manjari Medika grape seed extract, in ameliorating it. Methods and Results To assess the hepatological modulation, mice were divided into eight groups to investigate the ameliorative potential of this GSE (75 and 125 mg/kg) and correlate the experimental findings. The active components of the extract were assessed through UPLC-(ESI)-QToF-MS analysis. On the other hand, various biochemical and immunological indices were carried out to correlate the experimental data. The result demonstrated that the prophylactic administration of GSE reduced MTX-induced hepatic toxicity indices, which subsequently restored the hepatic morphological architecture. Moreover, the application of GSE in a dual dosage (75 and 125 mg/kg) suppressed MTX-induced reactive oxygen species generation, followed by lipid peroxidation and cellular nitrite formation. MTX-induced inflammasome activation through the redox-assisted cascade of TLR4/NF-κB signaling was further reduced by applying the GSE. The results showed that the activation of cytoprotective transcription factor Nrf2 enhanced the level of endogenous antioxidants. Furthermore, through the regulation of TLR4/NF-κB and Nrf2/HO-1 axis, this extract could reduce the MTX-mediated hepatic damage. Conclusion Our findings suggest that Manjari Medika seed extract could be used as a therapeutic agent to relieve the side effects of MTX and other hepatic disorders.

Abstract
The noncontagious immune-mediated skin disease known as psoriasis is regarded as a chronic skin condition with a 0.09-11.4% global prevalence. The main obstacle to the eradication of the disease continues to be insufficient treatment options. Sericin, a natural biopolymer from Bombyx mori cocoons, can improve skin conditions via its immunomodulatory effect. Many external therapeutic methods are currently used to treat psoriasis, but sericin-based hydrogel is not yet used to treat plaques of eczema. Through the use of an imiquimod rat model, this study sought to identify the physical and chemical characteristics of a silk sericin-based poly(vinyl) alcohol (SS/PVA) hydrogel and assess both its therapeutic and toxic effects on psoriasis. The cytokines, chemokines, and genes involved in the pathogenesis of psoriasis were investigated, focusing on the immuno-pathological relationships. We discovered that the SS/PVA had a stable fabrication and proper release. Additionally, the anti-inflammatory, antioxidant, and anti-apoptotic properties of SS/PVA reduced the severity of psoriasis in both gross and microscopic skin lesions. This was demonstrated by a decrease in the epidermal histopathology score, upregulation of nuclear factor erythroid 2-related factor 2 and interleukin (IL)-10, and a decrease in the expression of tumor necrosis factor (TNF)-α and IL-20. Moreover, the genes S100a7a and S100a14 were downregulated. Additionally, in rats given the SS/PVA treatment, blood urea nitrogen, creatinine, and serum glutamic oxaloacetic transaminase levels were within normal limits. Our findings indicate that SS/PVA is safe and may be potentiated to treat psoriasis in a variety of forms and locations of plaque because of its physical, chemical, and biological characteristics.

Abstract
Low-dose methotrexate (MTX) is a standard therapy for rheumatoid arthritis due to its low cost and efficacy. Despite these benefits, MTX has been reported to cause chronic drug-induced liver injury, namely liver fibrosis. The hallmark of liver fibrosis is excessive scarring of liver tissue, triggered by hepatocellular injury and subsequent activation of hepatic stellate cells (HSCs). However, little is known about the precise mechanisms through which MTX causes hepatocellular damage and activates HSCs. Here, we investigated the mechanisms leading to hepatocyte injury in HepaRG and used immortalized stellate cells (hTERT-HSC) to elucidate the mechanisms leading to HSC activation by exposing mono- and co-cultures of HepaRG and hTERT-HSC to MTX. The results showed that at least two mechanisms are involved in MTX-induced toxicity in HepaRG: (i) oxidative stress through depletion of glutathione (GSH) and (ii) impairment of cellular respiration in a GSH-independent manner. Furthermore, we measured increased levels of endoplasmic reticulum (ER) stress in activated HSC following MTX treatment. In conclusion, we established a human-relevant in vitro model to gain mechanistical insights into MTX-induced hepatotoxicity, linked oxidative stress in HepaRG to a GSH-dependent and -independent pathway, and hypothesize that not only oxidative stress in hepatocytes but also ER stress in HSCs contribute to MTX-induced activation of HSCs.

This study was aimed to evaluating the influences of methotrexate iontophoresis on functional lifestyle disabilities, functional capacity, and pain after a 6-min walking distance (6MWD) test in patients with plantar psoriasis (PP).
Patients and methods
Forty‑five patients (29 females, 16 males; mean age 33.9±6.6 years; range, 20 to 45 years) with hyperkeratotic PP were enrolled in the randomized, placebo-controlled, parallel-groups, double-blinded study. They were assigned randomly into the active methotrexate iontophoresis (MI) group (n=23) and the placebo iontophoresis group (n=22). The patients in both groups were assessed before starting the treatment intervention and after completing eight sessions of the treatment intervention through functional lifestyle disabilities measured on the Arabic version of psoriasis disability index, functional capacity using the 6MWD test, and pain after the 6MWD test.
Results
The pre-treatment measurements of the three variables among the two groups did not reveal statistically significant differences (p>0.05). However, there were statistically significant differences in the post-treatment results between the two groups (p<0.05). Additionally, the pre-and post-treatment values of the three outcome measures revealed statistically significant differences within the MI group (p<0.05). In contrast, there were no significant differences within the placebo group (p>0.05).
Conclusion
Methotrexate iontophoresis is effective in improving functional lifestyle disabilities, enhancing functional capacity, and decreasing pain in patients with PP.

Abstract
Introduction: Psoriasis vulgaris is a chronic skin disease which is characterized by recurrent scales on skin. The global prevalence of this disease has increased in ten years. Plumbagin is an active compound in the P. zeylanica Linn. Some recent studies revealed that P. zeylanica Linn extracts have the antiproliferative activity, which is used for treatment of some human diseases. The aim of this study was to investigated the effect of Chloroform extract of P. zeylanica Linn roots (CEP) on epidermal thickness of Imiquimod-induced psoriatic mice.
Methods: This was a post-test only control group design. A total of 42 male BALB/c mice was divided into six groups. Mice in treatment groups orally received 25, 50, and 100 mg/kg body weight CEP, respectively while positive control orally received 1 mg/kg body weight Methotrexate for seven days. Evaluation of epidermal thickness based on histological changes, serum IL-23 level by ELISA, and Cyclin-dependent kinase 2, Cyclin A, and Caspase-3 expressions by immunohistochemistry.
Results: Administrations of CEP decreased the epidermal thickness of psoriatic plaques in all treatment groups (p = 0.002, 0.003, and 0.016 respectively) compared to negative control but it did not reduce the serum IL-23 level. The expressions of CDK2 and Cyclin A reduced in T2 and T3 groups and the expression of Caspase-3 increased was only in T3 group.
Conclusion: Chloroform extract of P. zeylanica Linn roots administrations reduce the epidermal thickness of Imiquimod-induced psoriatic mice by inhibition of keratinocyte cell cycle and induction of Caspase-3 expression.

Psoriasis between Autoimmunity and Oxidative Stress: Changes Induced by Different Therapeutic Approaches. OXIDATIVE MEDICINE AND CELLULAR LONGEVITY 2022; 2022:2249834. [PMID: 35313642 PMCID: PMC8934232 DOI: 10.1155/2022/2249834] [Citation(s) in RCA: 17] [Impact Index Per Article: 8.5] [Reference Citation Analysis] [Abstract] [Track Full Text] [Download PDF] [Figures] [Subscribe] [Scholar Register] [Received: 10/22/2021] [Accepted: 02/15/2022] [Indexed: 12/15/2022]
Abstract
Psoriasis is defined as chronic, immune-mediated disease. Regardless of the development of new therapeutic approaches, the precise etiology of psoriasis remains unknown and speculative. The aim of this review was to systematize the results of previous research on the role of oxidative stress and aberrant immune response in the pathogenesis of psoriasis, as well as the impact of certain therapeutic modalities on the oxidative status in patients with psoriasis. Complex immune pathways of both the innate and adaptive immune systems appear to be major pathomechanisms in the development of psoriasis. Oxidative stress represents another important contributor to the pathophysiology of disease, and the redox imbalance in psoriasis has been reported in skin cells and, systemically, in plasma and blood cells, and more recently, also in saliva. Current immune model of psoriasis begins with activation of immune system in susceptible person by some environmental factor and loss of immune tolerance to psoriasis autoantigens. Increased production of IL-17 appears to be the most prominent role in psoriasis pathogenesis, while IL-23 is recognized as master regulator in psoriasis having a specific role in cross bridging the production of IL-17 by innate and acquired immunity. Other proinflammatory cytokines, including IFN-γ, TNF-α, IL-1β, IL-6, IL-22, IL-26, IL-29, or IL-36, have also been reported to play important roles in the development of psoriasis. Oxidative stress can promote inflammation through several signaling pathways. The most noticeable and most powerful antioxidative effects exert various biologics compared to more convenient therapeutic modalities, such as methotrexate or phototherapy. The complex interaction of redox, immune, and inflammatory signaling pathways should be focused on further researches tackling the pathophysiology of psoriasis, while antioxidative supplementation could be the solution in some refractory cases of the disease.

[PMID: 35204165 PMCID: PMC8868066 DOI: 10.3390/antiox11020282] [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: 01/09/2022] [Revised: 01/26/2022] [Accepted: 01/28/2022] [Indexed: 02/04/2023] Open
Abstract
Psoriasis is a chronic, immune-mediated inflammatory dermatosis characterized by the appearance of erythematous plaques, covered by white scales, occasionally pruritogenic, and distributed mainly on the extensor areas. Oxidative stress is defined as an imbalance or a transient or chronic increase in the levels of free oxygen/nitrogen radicals, either as a result of the exaggerated elevation in their production or the decrease in their ability to be eliminated by antioxidant systems. Although the pathogenesis of psoriasis remains far from elucidated, there are studies that delineate an involvement of oxidative stress in this skin disorder. Thus, a systematic search was computed in PubMed/Medline, Web of Science and SCOPUS and, in total, 1293 potentially eligible articles exploring this research question were detected. Following the removal of duplicates and the exclusion of irrelevant manuscripts based on the screening of their titles and abstracts (n = 995), 298 original articles were selected for full-text review. Finally, after we applied the exclusion and inclusion criteria, 79 original articles were included in this systematic review. Overall, the data analyzed in this systematic review point out that oxidative stress markers are elevated in psoriasis and share an association with the duration and severity of the disease. The concentrations of these biomarkers are impacted on by anti-psoriasis therapy. In addition, the crosstalk between psoriasis and oxidative stress is influenced by several polymorphisms that arise in genes encoding markers or enzymes related to the redox balance. Although the involvement of oxidative stress in psoriasis remains undisputable, future research is needed to explore the utility of assessing circulating serum, plasma, urinary and/or skin biomarkers of oxidative stress and of studying polymorphisms in genes regulating the redox balance, as well as how can these findings be translated into the management of psoriasis, as well in understanding its pathogenesis and evolution.

Abstract
Purpose The aim of the study is to examine the possible therapeutic effects of a known cardiac glycoside, digoxin, on a rat model of MTX-induced hepatotoxicity. Methods The study was conducted on twenty-four male rats. While eighteen rats received a single dose of 20 mg/kg MTX to obtain an injured liver model, six rats constituted the control group. Also, the eighteen liver toxicity model created rats were equally divided into two groups, one of which received digoxin 0.1 mg/kg/day digoxin (Group 1) and the other group (Group 2) was given saline (% 0.9NaCl) with a dose of 1 ml/kg/day for ten days. Following the trial, the rats were sacrificed to harvest blood and liver tissue samples to determine blood and tissue MDA, serum ALT, plasma TNF-α, TGF-β, IL-6, IL-1-Beta, and PTX3 levels. Results MTX's structural and functional hepatotoxicity was observable and evidenced by relatively worse histopathological scores and increased biochemical marker levels. Digoxin treatment significantly reduced the liver enzyme ALT, plasma TNF-α, TGF-β, PTX3, and MDA levels and decreased histological changes in the liver tissue with MTX-induced hepatotoxicity in the rat model. Conclusion We suggest that digoxin has an anti-inflammatory and antihepatotoxic effect on the MTX-induced liver injury model.

Abstract
Methotrexate is an important immunosuppressive and antineoplastic drug and is widely used for treatment. However, hepatotoxicity is one of the major adverse effects of methotrexate. In this study, it was aimed to investigate whether ramelteon has a possible protective effect on hepatotoxicity induced by methotrexate. Thirty-two Wistar albino rats were equally divided into four groups: control, methotrexate, methotrexate + ramelteon, and ramelteon. Following a single dose of 20 mg/kg, methotrexate (i.p.), either saline or ramelteon 10 mg/kg (orally) was administered for 7 days. After treatment, animals were sacrificed, and histopathological analyses were evaluated with Hematoxylin-eosin (H-E), immunohistological analyses were evaluated with Interleukın-1 Beta (IL-1β) and Caspase 3 (CAS-3), biochemical analyzes were evaluated with Total Oxidant Status (TOS), Total antioxidants status (TAS), Oxidative Stress Index (OSI), aspartate aminotransferase (AST), alanine aminotransferase (ALT) activities, at last genetical analyses were evaluated with Sirtuin-1 (SIRT-1) - P53 gene expressions. In the control and ramelteon groups, normal histological structures were observed, while histopathological findings were observed in the methotrexate group. Increasing levels of IL-1β staining, CAS-3 staining, p53 gene expression, TOS, OSI, AST and ALT were observed in methotrexate group while were observed decreasing levels of TAS and SIRT-1 gene expression (p < 0.05). However, ramelteon reduced the increased findings in methotrexate-induced hepatotoxicity (p < 0.05). The results of the present study showed that ramelteon protects against methotrexate induced hepatotoxicity in rats via SIRT-1 signaling by histological, immunohistological, biochemical and genetical analyses.

Antioxidant-rich fraction of Amomum subulatum fruits mitigates experimental methotrexate-induced oxidative stress by regulating TNF-α, IL-1β, and IL-6 proinflammatory cytokines. J Food Biochem 2021; 46:e13855. [PMID: 34250612 DOI: 10.1111/jfbc.13855] [Citation(s) in RCA: 7] [Impact Index Per Article: 2.3] [Reference Citation Analysis] [Abstract] [Key Words] [Journal Information] [Subscribe] [Scholar Register] [Received: 04/10/2021] [Revised: 06/24/2021] [Accepted: 06/25/2021] [Indexed: 12/30/2022]
Abstract
The culinary spice Amomum subulatum was assessed for its phytochemical composition, in vitro antioxidant potential, and in vivo ameliorating effect against methotrexate (MTX)-induced toxicities. Phytochemical analysis of methanolic extract of A. subulatum dry fruits (MEAS) confirmed the presence of different bioactive secondary metabolites. MEAS scavenged reactive free radicals and inhibited lipid peroxidation in vitro. To confirm the antioxidant efficiency of MEAS, in vivo experiment was carried out in which MTX was administered to induce oxidative stress. Co-administration of MEAS reduced MTX-induced hepatic, renal, and pulmonary toxicities via significantly (p < .01) enhancing antioxidant status and reducing oxidative stress. MTX treatment significantly (p < .01) increased liver and kidney toxicity markers and increased proinflammatory cytokine (TNF-α, IL-1β, and IL-6) levels. However, co-administration of MEAS significantly (p < .01) reduced their levels, and tissue histopathology confirmed the protective effect of MEAS in maintaining normal tissue architecture following MTX treatment. Protective effect of MEAS is accredited to the antioxidant and anti-inflammatory properties exhibited by bioactive compounds in MEAS. PRACTICAL APPLICATIONS: Amomum subulatum (Black cardamom) is a folkloric and culinary spice used for its organoleptic, nutritional, and medicinal properties. This study demonstrated the phytochemical composition and antioxidant potential of methanolic extract of A. subulatum dry fruits (MEAS). Toxicities associated with MTX therapy limit its clinical application. MEAS attenuated methotrexate-induced oxidative stress, inflammation, and associated organ damages, suggesting the possible therapeutic application of A. subulatum in reducing oxidative stress and associated diseases. Our results showed that A. subulatum is a potential functional food, which may be used for the betterment of health due to its richness in antioxidant and anti-inflammatory phytochemicals.

Abstract
Psoriasis is a chronic autoimmune skin disease driven by dysregulations at the cellular, genomic and genetic levels. MicroRNAs are key mediators of gene expression regulation. However, how microRNAs control the pathogenesis of psoriasis is still unclear. Here, we reported a significant up-regulation of miR-378a-3p (miR-378a) in skin biopsies from active psoriatic lesions while it was down-regulated after treatment with methotrexate or narrow-band ultraviolet B phototherapy. Using the keratinocyte in vitro model, we showed that miR-378a disturbed the cell cycle progression, causing cell cycle arrest at G1 phase. Transcriptomic analysis of keratinocytes with miR-378a overexpression and depletion revealed several important biological mechanisms related to inflammation and tight junction. Target mRNA transcript assessed by luciferase assay identified bone morphogenetic protein 2 as a novel target gene of miR-378a. These findings offer a mechanistic model where miR-378a contributes to the pathogenesis of psoriasis.

Abstract
Cellular redox state is highly dynamic and delicately balanced between constant production of reactive oxygen species (ROS), and neutralization by endogenous antioxidants, such as glutathione. Physiologic ROS levels can function as signal transduction messengers, while high levels of ROS can react with and damage various molecules eliciting cellular toxicity. The redox state is reflective of the cell’s metabolic status and can inform on regulated cell-state transitions or various pathologies including aging and cancer. Therefore, methods that enable reliable, quantitative readout of the cellular redox state are imperative for scientists from multiple fields. Liquid-chromatography mass-spectrometry (LC-MS) based methods to detect small molecules that reflect the redox balance in the cell such as glutathione, NADH, and NADPH, have been developed and applied successfully, but because redox metabolites are very labile, these methods are not easily standardized or consolidated. Here, we report a robust LC-MS method for the simultaneous detection of several redox-reactive metabolites that is compatible with parallel global metabolic profiling in mammalian cells. We performed a comprehensive comparison between three commercial hydrophilic interaction chromatography (HILIC) columns, and we describe the application of our method in mammalian cells and tissues. The presented method is easily applicable and will enable the study of ROS function and oxidative stress in mammalian cells by researchers from various fields.

Abstract
Inflammatory diseases, including psoriasis, are characterized by changes in redox regulation. The MTH1 prevents the incorporation of oxidized nucleotides during DNA replication. Using MTH1 small-molecule inhibitors, we found induced apoptosis through 8-oxodeoxyguanosine triphosphate accumulation and DNA double-strand breaks after oxidative stress in normal and malignant keratinocytes. In psoriasis, we detected increased MTH1 expression in lesional skin and PBMCs compared with that in the controls. Using the imiquimod psoriasis mouse model, we found that MTH1 inhibition diminished psoriatic histological characteristics and normalized the levels of neutrophils and T cells in the skin and skin-draining lymph nodes. The inhibition abolished the expression of T helper type 17‒associated cytokines in the skin, which was in line with decreased levels of IL-17-producing γδ T cells in lymph nodes. In human keratinocytes, MTH1 inhibition prevented the upregulation of IL-17‒downstream genes, which was independent of ROS-induced apoptosis. In conclusion, our data support MTH1 inhibition using small molecules suitable for topical application as a promising therapeutic approach to psoriasis.

Abstract
The most common oxidative DNA lesion is 8-oxoguanine which is mainly recognized and excised by the 8-oxoG DNA glycosylase 1 (OGG1), initiating the base excision repair (BER) pathway. Telomeres are particularly sensitive to oxidative stress (OS) which disrupts telomere homeostasis triggering genome instability. In the present study, we have investigated the effects of inactivating BER in OS conditions, by using a specific inhibitor of OGG1 (TH5487). We have found that in OS conditions, TH5487 blocks BER initiation at telomeres causing an accumulation of oxidized bases, that is correlated with telomere losses, micronuclei formation and mild proliferation defects. Moreover, the antimetabolite methotrexate synergizes with TH5487 through induction of intracellular reactive oxygen species (ROS) formation, which potentiates TH5487-mediated telomere and genome instability. Our findings demonstrate that OGG1 is required to protect telomeres from OS and present OGG1 inhibitors as a tool to induce oxidative DNA damage at telomeres, with the potential for developing new combination therapies for cancer treatment.

Abstract
Methotrexate (MTX) is widely used for treating cancers and inflammatory diseases; it is a potential anti-metabolite and folate antagonist. We investigated potential protective effects of benfotiamine on MTX damage. We used a rat model of MTX induced gastric injury to assess changes in gastric histopathology, oxidative stress and visfatin levels due to MTX treatment. Rats were divided into four groups: an untreated control group, an MTX group treated with a single dose of MTX, a benfotiamine group treated with benfotiamine daily for two weeks, and a benfotiamine + MTX group treated with a single dose of MTX followed by benfotiamine daily for two weeks. Total tissue antioxidant status (TAS), total oxidant status (TOS) and visfatin levels were measured at the end of the experiment. At the end of the experiment, we investigated both visfatin expression and the histopathology of gastric tissues. The mean visfatin level was lower in the MTX group than in the benfotiamine group. The mean tissue TOS levels were higher in MTX group than in the control, benfotiamine or benfotiamine + MTX groups. Significant gastric gland dilation, and erosion and loss of mucosa were found on the gastric surface in the MTX group compared to the control group. The dilation, erosion and mucosal loss were decreased significantly in the benfotiamine + MTX group compared to the MTX group. Compared to the control group, visfatin immunoreactivity was reduced significantly in the MTX group. Decreased visfatin levels appear to play a role in the mechanism of gastric damage. Benfotiamine may be useful for preventing MTX induced gastric injuries.

The Role of Oxidative Stress in Physiopathology and Pharmacological Treatment with Pro- and Antioxidant Properties in Chronic Diseases. OXIDATIVE MEDICINE AND CELLULAR LONGEVITY 2020; 2020:2082145. [PMID: 32774665 PMCID: PMC7396016 DOI: 10.1155/2020/2082145] [Citation(s) in RCA: 107] [Impact Index Per Article: 26.8] [Reference Citation Analysis] [Abstract] [Track Full Text] [Download PDF] [Figures] [Subscribe] [Scholar Register] [Received: 05/29/2020] [Accepted: 07/08/2020] [Indexed: 01/01/2023]
Abstract
Oxidative stress (OS) has the ability to damage different molecules and cellular structures, altering the correct function of organs and systems. OS accumulates in the body by endogenous and exogenous mechanisms. Increasing evidence points to the involvement of OS in the physiopathology of various chronic diseases that require prolonged periods of pharmacological treatment. Long-term treatments may contribute to changes in systemic OS. In this review, we discuss the involvement of OS in the pathological mechanisms of some chronic diseases, the pro- or antioxidant effects of their pharmacological treatments, and possible adjuvant antioxidant alternatives. Diseases such as high blood pressure, arteriosclerosis, and diabetes mellitus contribute to the increased risk of cardiovascular disease. Antihypertensive, lipid-lowering, and hypoglycemic treatments help reduce the risk with an additional antioxidant benefit. Treatment with methotrexate in autoimmune systemic inflammatory diseases, such as rheumatoid arthritis, has a dual role in stimulating the production of OS and producing mitochondrial dysfunction. However, it can also help indirectly decrease the systemic OS induced by inflammation. Medicaments used to treat neurodegenerative diseases tend to decrease the mechanisms related to the production of reactive oxygen species (ROS) and balance OS. On the other hand, immunosuppressive treatments used in cancer or human immunodeficiency virus infection increase the production of ROS, causing significant oxidative damage in different organs and systems without widely documented exogenous antioxidant administration alternatives.

Abstract
Background:
Psoriasis is an autoimmune disease that ingeminates itself with the repeated
proliferation of keratinocytes. It globally strikes a 2-5 % population on an average. Management
of psoriasis remains a daunting task with various challenges influencing treatment, such as patient
conformity and adherence to therapy, delicate patient profiles, psychological aspects, and skin as a
barrier to topical delivery. The first part reviewed pathophysiology, triggering factors, and clinical
classification. The second part reviewed all the therapies, such as topical, oral, biological, parenteral
therapy, phototherapy, and the phyto-pharmaceuticals.
Methods:
The research data related to the existing and upcoming therapies for psoriasis treatment,
several nanocarriers, existing marketed formulations, and detailed description of phytopharmaceuticals
with their mechanism.
Results:
Topical therapy is the mainstay treatment option with limited adverse effects. Biological therapy
has reformed conventional psoriasis treatment by being more efficacious and has increased patient
acceptance due to decreased adverse events. Nanoformulations present an edge over conventional
therapy due to improved anti-psoriatic effect and decreased side effects. Phyto-pharmaceuticals act as
a complementary and alternative therapy for diminishing psoriasis symptoms.
Conclusion:
A rationalized cost-effective patient compliant therapy is required for effective management
and complete cure of psoriasis.

Abstract
Background: Systemic methotrexate (MTX) is a useful treatment for many dermatologic conditions, however, the risk of adverse events prevents its use in patients with minimal or localized disease. Topical application of MTX may be an option to avoid the systemic adverse effects of oral MTX.Objective: To assess what is known about the efficacy and safety of topical methotrexate.Methods: A search on Pubmed was conducted. There were no limits on publication date.Results: A total of 963 articles were discovered. Using our exclusion criteria, 916 articles were excluded; 47 articles were used for full text assessment. Topical MTX has been used primarily in psoriasis but also in mycosis fungoides, lymphomatoid papulosis, and oral precancerous lesions. Optimal delivery system and formulation for adequate penetration is still under investigation.Conclusion: The quality of evidence for the utility of topical methotrexate in psoriasis is good, however, for other dermatologic diseases, the quality is poor. Topical MTX with improved delivery methods may be a viable tool against certain localized dermatologic conditions for patients who do not tolerate oral MTX. Further double-blinded randomized controled studies are needed to substantiate the utility of topical methotrexate.

Abstract
Objective To examine the efficacy of vitamin E in methotrexate- (MTX-) induced transaminitis in patients with rheumatoid arthritis (RA). Methods A case-control study was conducted at a tertiary rheumatology center for 12 months. Patients with RA on MTX and deranged aminotransferases were included. Patients with previous liver diseases, baseline transaminitis before methotrexate initiation, alcohol intake, muscle diseases, under hepatotoxic drugs, and aminotransferases > 3 times the upper normal limit were excluded. The patients were divided into treatment (vitamin E 400 mg bid for 3 months) and control groups (no vitamin E) using a random number table. The dose of MTX was unaltered. Follow-up was done after 3 and 6 months. Independent t-test was done to compare means of two groups. Paired t-test was done to compare differences in mean. Results Among 230 patients, 86.5% were female with a mean BMI of 25.9 ± 4.5 kg/m2. In the treatment group, SGPT and SGOT at baseline were 73.1 ± 20.4 and 60.2 ± 24.5 IU/L, respectively; at 3-month follow-up 44.6 ± 34.2 and 38.3 ± 20.8 IU/L, respectively; and at 6-month follow-up 40.4 ± 35.7 and 34.2 ± 21.9 IU/L, respectively. In the control group, SGPT and SGOT at baseline were 63.4 ± 15.1 and 46.8 ± 13.7 IU/L, respectively, and at 3-month follow-up 55.8 ± 45.9 and 45.5 ± 30.9 IU/L, respectively. Significant decrease in the level of aminotransferases was seen in the treatment group (p value < 0.001) and not in the control group (p values 0.161 and 0.728, respectively). The change in levels of SGPT and SGOT from baseline to 3 months of follow-up was statistically significant in between two study groups (p values 0.007 and <0.001, respectively). From the control group, 29 patients were crossed over to vitamin E for the next 3 months. SGPT and SGOT decreased from 97.6 ± 44.1 to 46.1 ± 40.9 and 69.3 ± 34.9 to 29.1 ± 11.6 IU/L, respectively (p values 0.031 and 0.017, respectively). Conclusion Vitamin E significantly attenuates MTX-induced transaminitis.

Abstract
BACKGROUND The clinical application of methotrexate (MTX), an efficacious cytotoxic drug, is restricted due to its associated liver toxicity. Ellagic acid (EA), a natural polyphenol, possesses hepatoprotective, antioxidant and anti-inflammatory properties. OBJECTIVES The present study seeks to address the hepatoprotective effects of Ellagic acid (EA) against MTX-mediated oxidative stress (OS) and widen our current knowledge of the underlying molecular mechanisms of MTX toxicity. METHODS Wistar rats were orally given EA (5 mg/kg and 10 mg/kg) for 10 successive days and at the end of the third day they were administered a single dose of MTX (20 mg/kg i.p). RESULTS After performing biochemical analysis, liver enzymes and malondialdehyde were significantly higher in the MTX group, indicating hepatic oxidative damage. MTX-induced OS was further confirmed with observation of events such as reactive oxygen species (ROS) overproduction, mitochondrial outer membrane potential decrease, mitochondrial swelling, cytochrome c release and caspase-3/9 increase, resulting in apoptosis. Furthermore, overexpression of pro-inflammatory factors such as nuclear factor kappa B (NF-ĸB) and interleukin 6 (IL-6) indicated the MTX-induced inflammation in MTX-treated group. Interestingly, EA was able to significantly prevent OS, mitochondrial dysfunction, apoptosis and inflammation induced by MTX. Also, EA-treated rats demonstrated significant upregulation of both nuclear factor erythroid 2-related factor 2 (Nrf2) and hemoxygenase-1 (HO-1), which were considerably downregulated in MTX-treated rats. CONCLUSIONS EA protects rats against MTX-induced apoptosis and mitochondrial dysfunction via up-Regulating Nrf2 and HO-1 expression and inhibiting the NF-κB signaling pathway. Therefore, EA may protect patients against MTX-induced hepatotoxicity and encourage its clinical application.

Abstract
Zika virus (ZIKV), which is associated with microcephaly in infants and Guillain-Barré syndrome, reemerged as a serious public health threat in Latin America in recent years. Previous high-throughput screening (HTS) campaigns have revealed several potential hit molecules against ZIKV, including methotrexate (MTX), which is clinically used as an anti-cancer chemotherapy and anti-rheumatoid agent. We studied the mechanism of action of MTX against ZIKV in relation to its inhibition of dihydrofolate reductase (DHFR) in vitro using Vero and human neural stem cells (hNSCs). As expected, an antiviral effect for MTX against ZIKV was observed, showing up to 10-fold decrease in virus titer during MTX treatment. We also observed that addition of leucovorin (a downstream metabolite of DHFR pathway) rescued the ZIKV replication impaired by MTX treatment in ZIKV-infected cells, explaining the antiviral effect of MTX through inhibition of DHFR. We also found that addition of adenosine to ZIKV-infected cells was able to rescue ZIKV replication inhibited by MTX, suggesting that restriction of de novo synthesis adenosine triphosphate (ATP) pools suppresses viral replication. These results confirm that the DHFR pathway can be targeted to inhibit replication of ZIKV, similar to other published results showing this effect in related flaviviruses.

Abstract
This study investigated oxidative stress in patients with psoriasis of low and medium disease activity. We measured advanced oxidation protein products (AOPP) and malondialdehyde (MDA) in plasma using UV-spectrophotometry and high performance liquid chromatography connected to a fluorescence detector in 84 patients and 84 matched healthy subjects. AOPP is a marker of protein oxidation due to inflammation, whereas MDA is a hydroxyl radical initiated lipid peroxidation product. Clinico-demographic variables including age, gender, disease severity, and fatigue were assessed in relation to AOPP and MDA. Disease severity was evaluated with the Psoriasis Area and Severity Index and the Dermatology Life Quality Index. Median (interquartile range, IQR) AOPP concentrations were 66 µmol/l (IQR 54-102) in patients and 69 µmol/l (IQR 55-87) in healthy subjects (P = 0.75). Median plasma MDA concentrations were significantly lower in patients than in healthy subjects (0.68 µM, IQR 0.54-0.85 vs. 0.76 µM, IQR 0.60-0.97; P = 0.03). Plasma levels of AOPP and MDA did not indicate oxidative stress in patients with mild psoriasis. Higher AOPP concentrations were associated with male gender, high body mass index, and high hemoglobin values. Elevated MDA concentrations were associated with advanced age and male gender. No associations with disease severity were detected. Although, the two selected biomarkers do not provide a complete measure of oxidative damage, our study demonstrates that a number of physiological and methodological factors influence the levels of MDA and AOPP. Such methodological issues are important to consider when interpreting results using these biomarkers in patients with psoriasis.

Abstract
Psoriasis is a chronic hyperproliferative skin disease characterised by excessive growth of keratinocytes. Indeed, inducing keratinocyte apoptosis is a key mechanism responsible for psoriatic plaques clearance following some important existing therapies, which display pro-oxidant activity. Cold atmospheric plasma (CAP), acting as a tuneable source of reactive oxygen and nitrogen species (RONS), can controllably transfer RONS to the cellular environment, deliver antiproliferative RONS concentrations and exert antiproliferative and proapoptotic effects. This study was undertaken to evaluate the therapeutic potential of CAP in psoriasis. We used cell models of psoriasis-like inflammation by adding lipopolysaccharide (LPS) or tumour necrosis factor alpha (TNF-α) to HaCaT keratinocytes. Indirect plasma, plasma-activated medium (PAM), was administered to HaCaT cells. Atmospheric pressure plasma jet (APPJ) was applied directly to imiquimod (IMQ)-induced psoriasiform dermatitis in mice. The results showed that PAM induced an increase in intracellular ROS and caused keratinocyte apoptosis. Moreover, cells under inflammation showed lesser viability and larger apoptosis rate. With repeated administration of APPJ, psoriasiform lesions showed ameliorated morphological manifestation and reduced epidermal proliferation. Overall, this study supports that CAP holds good potential in psoriasis treatment.

Abstract
BACKGROUND Psoriasis is a T-helper (Th)1/Th17-mediated chronic inflammatory disease. There is an increased population of Th cells in skin lesions and peripheral circulation of patients with psoriasis. Systemic methotrexate (MTX) is an effective treatment for moderate to severe psoriasis; however, its effect on different T-cell subsets is not yet clear. AIM To study the effect of MTX monotherapy on the psoriatic T-cell profile in the peripheral circulation of patients with psoriasis. METHODS This was a follow-up study involving 50 patients with moderate to severe psoriasis treated with systemic MTX for 12 weeks. Blood samples (5 mL) were collected from participants, from which PBMCs were isolated, and T-cell phenotyping was performed by flow cytometry. RESULTS Following 12 weeks of MTX treatment, there was an increase in the percentages of Th2/Treg cells, and a relative decrease in the percentages of Th1/Th17 cells, along with a significant reduction in the median Psoriasis Area and Severity Index (PASI). CONCLUSION MTX helps in the restoration of the immune balance by decreasing the numbers of Th1 and Th17 cells and increasing the numbers of Th2 and Treg cells, thus resulting in a significant reduction in disease severity. MTX converts a proinflammatory T-cell phenotype to a protective anti-inflammatory phenotype, thus significantly suppressing the inflammation in psoriasis.

Psoriasis is a chronic inflammatory disease that affects approximately 7.5 million people in the United States. The disease results in significant suffering, morbidity, and economic impact. Psoriasis is a multifaceted disease with a strong genetic component. Genetic data has revealed the presence of particular risk alleles in patients with psoriasis. Triggers of the disease have been elucidated and include factors such as trauma, obesity, infection, stress, and medications. At its core, psoriasis is a result of a dysfunctional immune response with T-cells at the center of immunogenesis. Clinically, psoriasis is characterized by discrete, erythematous scaly plaques. These lesions are often found on extensor surfaces, especially the elbows and knees. Although extensor surfaces are the prototypical destination of lesions, psoriasis may affect any area of the skin including the scalp, intertriginous areas, nails, palms, and soles. Location of lesions are important in assessing the impact on quality of life for patients. Diagnosis of psoriasis can typically be made clinically based on characteristic history and physical examination findings. In rare cases, biopsy may be needed to rule out other papulosquamous disease. Histologic findings of psoriasis can be non-specific and include marked epidermal hyperplasia, dilated vessels within the dermal papilla, and elongated rete ridges. Importantly, psoriasis is a systemic disease and organ systems outside of the skin must be considered. Co-morbidities of psoriasis include psoriatic arthritis, type 2 diabetes mellitus, cardiovascular disease, psychiatric disease, inflammatory bowel disease, neoplasms, and ocular disease. Management of psoriasis depends on the severity of the disease. In mild to moderate cases, topical medications are the cornerstone of treatment. Topical corticosteroids are the most commonly used and have limited systemic effects due to the localized application of medication. In moderate to severe cases of psoriasis, topical medications are ineffective and not feasible. Phototherapy and non-biologic systemic medications have been useful treatments; however, phototherapy is time consuming and non-biologic systemics have only modest response rates. In the last decade, biologic medications have become an important component of care for treating moderate to severe psoriasis. These medications target various cytokines responsible for psoriasis manifestations such as tumor necrosis factor (TNF-α), interleukin-12, interleukin-23, and interleukin-17. In the past 15 years, numerous biologic medications have been granted FDA approval, with the majority approved in the past several years. Some of the commonly used biologics include etanercept, adalimumab, infliximab, ixekizumab, secukinumab, brodalumab, guselkumab, ustekinumab, and tildrakizumab. Given the wealth of new biologics, current treatment guidelines have rapidly become outdated. This review provides summarized information of landmark trials that led to the approval of these medications.

Abstract
Psoriasis is a commonly encountered chronic dermatological disease, presenting with inflammatory symptoms in patients. Systemic treatment of psoriasis is associated with several adverse effects, therefore the development of a customized topical treatment modality for psoriasis would be an interesting alternative to systemic delivery. The therapeutic modality explored in this article was the comparative treatment of psoriatic patients using nanoparticulated methotrexate in the form of jojoba oil-based microemulsion with or without fractional erbium YAG laser. Assessment parameters included follow-up photography for up to 8 weeks of treatment, estimation of the psoriasis severity [TES (thickness, erythema, scales)] score, and histopathological skin evaluation. The prepared methotrexate microemulsion was clinically beneficial and safe in treatment of psoriasis vulgaris. The concomitant use of the fractional laser provided improvement in the psoriatic plaques within shorter time duration (3 weeks compared to 8 weeks of treatment), presenting an alternative topical treatment modality for psoriasis vulgaris.

Abstract
Purpose: Methotrexate (MTX) is prescribed in many diseases and can result in oxidative stress (OS) followed by injuries in some tissues. Antioxidants administration are effective in reducing OS. Pomegranate exhibits high anti-oxidant capacities. This study investigated whether pomegranate seed and peel methanolic extracts (PSE and PPE) could protect against MTX-induced OS and lipid profile changes in rats. Methods: Forty-eight rats were randomly divided into 6 groups: control group (normal salin), PSE group (500 mg/kg, orally), PPE group (500 mg/kg, orally), MTX group (10 mg/kg, IM), MTX and PSE group, and MTX and PPE group. Blood samples were taken for analysis in the end of the procedure. Results: The findings showed a significant reduction in Glutathione peroxidase (GPx) and Superoxide dismutase (SOD), and an enhancement in malondialdehyde (MDA) values after MTX treatment (p < 0.05). SOD and GPx levels reached the levels of the control group in MTX+SPE and MTX+PPE groups. No significant differences were observed in catalase (CAT) and total antioxidant capacity (TAC) levels between groups. The results showed a significant decrease in total cholesterol (TC), low density lipoprotein (LDL), and high density lipoprotein (HDL) in the MTX treated group (p < 0.01). The values of TC, HDL, and LDL became elevated to the normal control levels in the MTX+PSE and MTX+PPE treated groups. Conclusion: The results showed the OS induced by MTX and the protective effects of PSE and PPE against MTX-induced serum oxidative stress and lipid profile changes in rats.

Pharmacogenetic markers to predict the clinical response to methotrexate in south Indian Tamil patients with psoriasis. Eur J Clin Pharmacol 2017; 73:965-971. [PMID: 28444425 DOI: 10.1007/s00228-017-2255-x] [Citation(s) in RCA: 30] [Impact Index Per Article: 4.3] [Reference Citation Analysis] [Abstract] [Key Words] [Track Full Text] [Journal Information] [Subscribe] [Scholar Register] [Received: 10/24/2016] [Accepted: 04/12/2017] [Indexed: 01/31/2023]
Abstract
INTRODUCTION Despite the advent of several new systemic therapies, methotrexate remains the gold standard for the treatment of moderate to severe psoriasis. However, there exists a significant heterogeneity in individual response to methotrexate. There are no consistently reliable markers to predict methotrexate treatment response till date. OBJECTIVES We aimed to demonstrate the association of certain genetic variants in the HLA (HLA-A2, HLA-B17, and HLA-Cw6) and the non-HLA genes including T-helper (Th)-1, Th-2, Th-17 cytokine genes (IFN-γ, IL-2, IL-4, IL-10, IL-12B, and IL-23R), and T-regulatory gene (FOXP3) with the methotrexate treatment response in South Indian Tamil patients with psoriasis. METHODS Of the 360 patients recruited, 189 patients with moderate to severe psoriasis were treated with methotrexate. Of the 189 patients, 132 patients responded to methotrexate and the remaining 57 patients were non-responders. We analyzed the association of aforesaid polymorphisms with the methotrexate treatment outcome using binary logistic regression. RESULTS We observed that there were significant differences between genotype frequencies of HLA-Cw6 and FOXP3 (rs3761548) among the responders compared to non-responders, with conservative estimation. We observed that pro-inflammatory cytokines such as IFN-γ, IL-2, IL-12, and IL-23 were markedly reduced with the use of methotrexate, in comparison to the baseline levels, while the plasma IL-4 levels were increased posttreatment. CONCLUSION Our results serve as preliminary evidence for the clinical use of genetic markers as predictors of response to methotrexate in psoriasis. This might aid in the future in the development of a point-of-care testing (POCT) gene chip, to predict optimal treatment response in patients with psoriasis, based on their individual genotypic profile.

Abstract
BACKGROUND For decades, methotrexate (MTX; amethopterin) has been known as an antifolate inhibitor of dihydrofolate reductase (DHFR), and it is widely used for the treatment of various malignancies and autoimmune diseases. Although the inclusion of MTX in various therapeutic regimens is based on its ability to inhibit DHFR and consequently to suppress the synthesis of pyrimidine and purine precursors, recent studies have shown that MTX is also able to target other intracellular pathways that are independent of folate metabolism. SCOPE OF REVIEW The main aim of this review is to summarize the most important, up-to-date findings of studies regarding the non-DHFR-mediated mechanisms of MTX action. MAJOR CONCLUSIONS The effectiveness of MTX is undoubtedly caused by its capability to affect various intracellular pathways at many levels. Although the most important therapeutic mechanism of MTX is strongly based on the inhibition of DHFR, many other effects of this compound have been described and new studies bring new insights into the pharmacology of MTX every year. GENERAL SIGNIFICANCE Identification of these new targets for MTX is especially important for a better understanding of MTX action in new protocols of combination therapy.

Abstract
Severe, recalcitrant dermatologic conditions often require systemic treatment. Although efficacious, these medications have been associated with wide-ranging adverse reactions. Some are reversible, predictable, and either dose-dependent or treatment length-dependent, while others are unpredictable, irreversible, and potentially fatal. This review examines the neuropsychiatric adverse effects associated with US FDA-approved medications for treatment of the following dermatologic pathologies that typically require systemic therapy: autoimmune dermatoses, acne, psoriasis, and melanoma. A search of the literature was performed, with adverse effects ranging from mild headaches and neuropathy to severe encephalopathies. The medications associated with the most serious reactions were those used to treat psoriasis, especially the older non-biologic medications such as cyclosporine A and methotrexate. Given the importance of these systemic dermatologic therapies in treating severe, recalcitrant conditions, and the wide variety of potentially serious neuropsychiatric adverse effects of these medications, neurologists, psychiatrists, dermatologists, oncologists, and primary care providers must be aware of the potential for these neuropsychiatric adverse reactions to allow for appropriate counseling, management, and medication withdrawal.

Abstract
Background Hepatocellular carcinoma (HCC) is one of the most common malignant cancers worldwide and is associated with substantial mortality. Because HCCs have strong resistance to conventional chemotherapeutic agents, novel therapeutic strategies are needed to improve survival in HCC patients. Methods Here, we developed a fluorescence image-based phenotypic screening system in vitro to identify HCC-specific drugs in co-cultures of HCC cells with hepatocytes. To this end, we identified two distinctive markers of HCC, CHALV1 and AFP, which are highly expressed in HCC cell lines and liver cancer patient-derived materials. We applied these markers to an HCC-specific drug screening system. Results Through pilot screening, we identified three anti-folate compounds that had HCC-specific cytotoxicity. Among them, pyrimethamine exhibited the greatest HCC-specific cytotoxicity. Interestingly, pyrimethamine significantly increased the size and number of lysosomes and subsequently induced the release of cathepsin B from the lysosome to the cytosol, which triggered caspase-3-dependent apoptosis in Huh7 (HCC) but not Fa2N-4 cells (immortalized hepatocytes). Importantly, Fa2N-4 cells had strong resistance to pyrimethamine relative to Huh7 cells in 2D and 3D culture systems. Conclusion These results demonstrate that this in vitro image-based phenotypic screening platform has the potential to be widely adopted in drug discovery research, since we promptly estimated anticancer activity and hepatotoxicity and elucidated functional roles of pyrimethamine during the apoptosis process in HCC.

Methotrexate treatment provokes apoptosis of proliferating keratinocyte in psoriasis patients. Clin Exp Med 2016; 17:371-381.

Abstract
Psoriasis is a chronic inflammatory skin disease characterized by hyper proliferation of keratinocytes. Recent data show that the epidermis thickening in psoriasis may be related to imbalance of homeostasis caused by abnormal apoptotic process. Maintenance of keratinocyte apoptotic process is very important in psoriasis. Methotrexate (MTX) has been used for many years to restore the normal skin in psoriasis condition. However, the exact mechanism of MTX in psoriasis condition is poorly understood. The aim of this study was to examine the role of MTX on keratinocyte apoptosis pathway in psoriasis patients. A total of 58 psoriasis vulgaris patients were recruited for this study. Nonlesional skin biopsies served as control. Skin biopsies of psoriatic patients were collected and analyzed for cytosolic, mitochondria and total cytochrome c by ELISA. Expression of caspase-9, NFκBp65, pAkt1 by western blot, real-time PCR and immunohistochemical analysis of c-FLIP protein was analyzed in nonlesional and lesional skin biopsies before (day 0) and after (at the end of 6 and 12 weeks) MTX treatment. After MTX treatment, a significant increase in cytochrome c was observed when compared with before MTX treatment in psoriasis patients (p < 0.001). Protein and gene expression of cleaved caspase-9 were significantly increased after MTX treatment, whereas the expression of Bcl-xL, c-FLIP, NFκBp65, pAkt1 significantly downregulated after MTX treatment. In conclusion, these results showed that intrinsic apoptotic pathway induced by MTX eventually adds the beneficial therapeutic role of MTX in psoriasis by controlling the acanthosis.

Abstract
Systemic biomarkers of oxidative stress can be relevant for assessment of psoriasis severity, for prediction of the outcome of therapy and of the development of comorbidities. In this review we aimed to evaluate the relationship between plasma total antioxidant capacity (TAC) and peroxidation biomarkers, as well as their association with dyslipidemia and systemic inflammation in psoriasis. The review of 59 case–control comparisons (from 41 studies) and 17 interventions (from 13 studies) suggests that peroxidation markers are more sensitive than TAC in the evaluation of oxidative stress in psoriasis. Although few studies investigated the effect of treatment on oxidative stress, it seems that biological drugs could be the better choice in the treatment of psoriasis. However, considering the limitations of TAC and plasma peroxidation markers, this review suggests that new methods should be developed in order to evaluate systemic oxidative stress in psoriasis.

Abstract
BACKGROUND AND OBJECTIVES Recent studies have implicated the association between oxidative stress and inflammation in pathogenesis of psoriasis and its associated comorbidities. Hence, we undertook to study inflammatory markers such as sialic acids and the oxidative stress index (OSI) in patients with psoriasis vulgaris. METHODS Sixty cases and 60 healthy controls were included in this cohort study. Disease severity was assessed by psoriasis area severity index scoring. Serum levels of oxidative stress (total oxidant status, total antioxidant status) and inflammation (highly sensitive C-reactive protein [hs-CRP], total sialic acid, protein bound sialic acid) markers were estimated in controls and cases at baseline and on follow-up. OSI was calculated as the ratio of total oxidant status to total antioxidant status. RESULTS Baseline serum levels of OSI, hs-CRP, and sialic acids were significantly higher in cases compared to controls. Baseline OSI and sialic acids demonstrated a significant correlation with disease severity. After 12 weeks of therapy, there was a significant decline in OSI and serum levels of hs-CRP and sialic acids. CONCLUSIONS Our results demonstrate that oxidative stress and inflammation are significantly associated with psoriasis, and treatment with methotrexate results in a significant decline of both the inflammatory and oxidative stress parameters.

Abstract
Psoriasis is a chronic multifactorial disease affecting 2–4% of the general population. Due to its nature, psoriasis has a negative impact on the quality of life of patients. Therefore, the choice of an appropriate and individually tailored treatment controlling the symptoms of the disorder is necessary and continues to be a challenge for dermatologists. Therapeutic modalities in psoriasis should on the one hand be effective and on the other hand present a good safety profile. Methotrexate (MTX) is one of treatment options for psoriasis and can be administered both as monotherapy or in combination schemes. The paper presents the current state of knowledge about the possible treatment of psoriatic patients with MTX according to contemporary guidelines.

Abstract
Methotrexate (MTX) is a folic acid antagonist used in high doses as an anti-cancer treatment and in low doses for the treatment of some autoimmune diseases. MTX use has been linked to oxidative imbalance, which may cause multi-organ toxicities that can be attenuated by antioxidant supplementation. Despite the oxidative effect of MTX, the influence of antioxidant gene polymorphisms on MTX toxicity is not well studied. Therefore, we analyzed here whether a genetic imbalance of the manganese-dependent superoxide dismutase (SOD2) gene could have some impact on the MTX cytotoxic response. An in vitro study using human peripheral blood mononuclear cells (PBMCs) obtained from carriers with different Ala16Val-SOD2 genotypes (AA, VV and AV) was carried out, and the effect on cell viability and proliferation was analyzed, as well as the effect on oxidative, inflammatory and apoptotic markers. AA-PBMCs that present higher SOD2 efficiencies were more resistance to high MTX doses (10 and 100 µM) than were the VV and AV genotypes. Both lipoperoxidation and ROS levels increased significantly in PBMCs exposed to MTX independent of Ala16Val-SOD2 genotypes, whereas increased protein carbonylation was observed only in PBMCs from V allele carriers. The AA-PBMCs exposed to MTX showed decreasing SOD2 activity, but a concomitant up regulation of the SOD2 gene was observed. A significant increase in glutathione peroxidase (GPX) levels was observed in all PBMCs exposed to MTX. However, this effect was more intense in AA-PBMCs. Caspase-8 and -3 levels were increased in cells exposed to MTX, but the modulation of these genes, as well as that of the Bax and Bcl-2 genes involved in the apoptosis pathway, presented a modulation that was dependent on the SOD2 genotype. MTX at a concentration of 10 µM also increased inflammatory cytokines (IL-1β, IL-6, TNFα and Igγ) and decreased the level of IL-10 anti-inflammatory cytokine, independent of SOD2 genetic background. The results suggest that potential pharmacogenetic effect on the cytotoxic response to MTX due differential redox status of cells carriers different SOD2 genotypes.

Abstract
The imbalance of the intracellular redox state and, in particular, of the glutathione (GSH)/GSH disulfide couple homeostasis, is involved in the pathogenesis of a number of diseases. In many skin diseases, including psoriasis, oxidative stress plays an important role, as demonstrated by the observation that treatments leading to increase of the local levels of oxidant species ameliorate the disease. Recently, dehydrocostuslactone (DCE) and costunolide (CS), two terpenes naturally occurring in many plants, have been found to exert various anti-inflammatory and pro-apoptotic effects on different human cell types. These compounds decrease the level of the intracellular GSH by direct interaction with it, and, therefore, can alter cellular redox state. DCE and CS can trigger S-glutathionylation of various substrates, including the transcription factor STAT3 and JAK1/2 proteins. In the present study, we investigated on the potential role of DCE and CS in regulating inflammatory and proliferative responses of human keratinocytes to cytokines. We demonstrated that DCE and CS decreased intracellular GSH levels in human keratinocytes, as well as inhibited STAT3 and STAT1 phosphorylation and activation triggered by IL-22 or IFN-γ, respectively. Consequently, DCE and CS decreased the IL-22- and IFN-γ-induced expression of inflammatory and regulatory genes in keratinocytes, including CCL2, CXCL10, ICAM-1 and SOCS3. DCE and CS also inhibited proliferation and cell-cycle progression-related gene expression, as well as they promoted cell cycle arrest and apoptosis. In parallel, DCE and CS activated the anti-inflammatory EGFR and ERK1/2 molecules in keratinocytes, and, thus, wound healing in an in vitro injury model. In light of our findings, we can hypothesize that the employment of DCE and CS in psoriasis could efficiently counteract the pro-inflammatory effects of IFN-γ and IL-22 on keratinocytes, revert the apoptosis-resistant phenotype, as well as inhibit hyperproliferation in the psoriatic epidermis.
