Methotrexate (MTX) is one of the most commonly prescribed and most effective drugs for the treatment of rheumatoid arthritis (RA). Given the partial response of many patients and the side effect profile of the drug, there is considerable interest in identifying biomarkers to guide MTX therapy in RA. Upon entering cells, MTX is polyglutamated. Measuring MTX polyglutamate (MTX PG) levels in circu...
OBJECTIVE To investigate whether silibinin (SDH) could overcome chemoresistance of methotrexate (MTX)-resistant human rhabdomyosarcoma (hRD). METHODS This study was conducted at the Department of Pharmacology and Toxicology, College of Pharmacy, University of Baghdad, Baghdad, Iraq from October 2012 to March 2013. In this in vitro study, resistance to MTX was induced in hRD cell line, the cel...
To avoid systemic toxicity of the cytotoxic drug methotrexate (MTX) and to improve tumor selectivity, MTX was bound to human serum albumin (HSA) as a drug carrier. To understand more about the mechanism of action of MTX conjugated to HSA (MTX-HSA), the uptake of MTX-HSA into the cell was determined as well as the effect of MTX-HSA on thymidylate synthase (TS), cell cycle distribution, and cell ...
Purpose:To evaluate the correlation between serum methotrexate (MTX) peak levels and clinical outcome of osteosarcoma, as well as to determine the correlation of these levels with the histologic response and event-free survival (EFS). Methods:To maintain the homogeneity of the study population, we selected 52 patients with localized extremity osteosarcoma who had received two cycles of neoadjuv...
Background: The application of methotrexate (MTX) as a chemotherapy agent and immune system suppressant has various side effects. Crocin, a xanthine derivative plant, has many therapeutic benefits. This study was planned to assess the effect of crocin on renal toxicity of MTX in a rat model. Methods: Forty eight rats were divided randomly into eight groups (n = 6), which received normal saline,...
OBJECTIVES To assess the variation of peripheral blood and bronchoalveolar lavage (BAL) inflammatory cell counts and lung biopsy findings with the degree of exposure to MTX therapy. METHODS Fifty-six (16 males; 40 females) reported cases of MTX-induced pneumonitis (MTX-P) on low-dose MTX (5-30 mg) were identified from a literature search and classified using Searles and McKendry's criteria. T...
PURPOSE ABCC2 (MRP2) and ABCG2 (BCRP) transport various endogenous and exogenous compounds, including many anticancer drugs, into bile, feces, and urine. We investigated the possibly overlapping roles of Abcg2 and Abcc2 in the elimination of the anticancer drug methotrexate (MTX) and its toxic metabolite 7-hydroxymethotrexate (7OH-MTX). EXPERIMENTAL DESIGN We generated and characterized Abcc2...
Rheumatoid arthritis (RA) is an inflammatory autoimmune disease characterized by joint destruction and severe morbidity. Methotrexate (MTX) is the standard first-line therapy of RA. However, about 40% of RA patients are unresponsive to MTX treatment. Regulatory T cells (Tregs, CD4(+)CD25(+)FoxP3(+)) are thought to play an important role in attenuating RA. To investigate the role of Tregs in MTX...
Methotrexate (MTX) as a chemotherapeutic agent, has adverse effects on reproductive organs by enhancing oxidative stress. In this study, the protective effects of Cornus mas fruit extract (CMFE) against MTX side effects were evaluated. Forty-eight mature male NMRI mice were divided into six groups: group 1 (control) received 0.10 mL per day of normal saline intraperitoneally (IP), grou...
OBJECTIVE We undertook this phase III study to evaluate baricitinib, an orally administered JAK-1/JAK-2 inhibitor, as monotherapy or combined with methotrexate (MTX) compared to MTX monotherapy in patients with active rheumatoid arthritis (RA) who had received no or minimal conventional synthetic disease-modifying antirheumatic drugs (DMARDs) and who were naive to biologic DMARDs. METHODS A t...
