The therapeutic effect of methotrexate (MTX)-conjugated Pluronic-based polymeric mixed micelles (F127/P105-MTX) on the folate receptor-overexpressing tumors treatment was investigated in this study. Due to its high structural similarity to folic acid and the high expression of folate receptor in most solid tumors, MTX serves as not only a cytotoxic agent but also a homing ligand. Cellular uptak...
LHRH receptor, is over-expressed in a variety of human tumors and, is a potential binding site for targeted metastatic prostate cancer therapy. The objectives of our study were to synthesize a bioconjugate of the LHRH analog [DLys6]-LHRH and the anti-tumor agent methotrexate and test the hypothesis that [DLys6]-LHRH-MTX targets and inhibits prostate cancer cell growth in vitro and in vivo. The ...
OBJECTIVE To study factors associated with toxicity, final dose, and efficacy of methotrexate (MTX) in patients with rheumatoid arthritis (RA). METHODS Data were used from a randomised clinical 48 week trial on 411 patients with RA all treated with MTX, comparing folates and placebo. Logistic regression was used to study the relation between baseline variables and various dependent factors, i...
OBJECTIVES Rheumatoid arthritis (RA) is a chronic inflammatory disease primarily affecting the synovial joints of the body. Methotrexate (MTX) is considered as a mainstay in the management of RA. However, monotherapy with MTX in RA is often limited by potential long-term toxicity. The present study was conducted to evaluate if MTX-pioglitazone combination therapy has an add-on benefit over mono...
The antifolate drugs methotrexate (MTX) and aminopterin (AM) have been tested as substrates for folylpolyglutamate synthetase (FPGS) partially purified from beef liver. The Km for MTX is 100 microM, and that for AM is 25 microM. These values are considerably higher than those for either tetrahydrofolate or folinic acid. Based on their ratios of Vmax to Km, AM is a better substrate than is MTX f...
INTRODUCTION This study evaluated various remission criteria in abatacept plus methotrexate (MTX)-treated patients with early rheumatoid arthritis (RA). We aimed to investigate the time to, and sustainability of, remission, and to evaluate the relationship between remission, function and structure. METHODS Post hoc analyses were performed from the 12-month, double-blind period of the Abatacep...
OBJECTIVE To assess radiographic progression, physical function, clinical disease activity, and safety in patients with rheumatoid arthritis (RA) who had inadequate response to methotrexate (MTX) and who were treated with tocilizumab-MTX or MTX during Year 2 of a 2-year study. METHODS During Year 1, patients were randomized to placebo-MTX, 4 mg/kg tocilizumab-MTX, or 8 mg/kg tocilizumab-MTX. ...
Today, the therapeutic efficacy of cancer is restricted by the heterogeneity of the response of tumor cells to chemotherapeutic drugs. Since those therapies are also associated with severe side effects in nontarget organs, the application of drugs in combination with nanocarriers for targeted therapy has been suggested. Here, we sought to assess whether the coupling of methotrexate (MTX) to mag...
OBJECTIVE The purpose of this experimental study was to evaluate the efficacy of carvacrol (CVR) and pomegranate (PMG) against methotrexate (MTX)-induced intestinal damage using histopathological and immunohistochemical techniques. METHODS Thirty-two male Sprague-Dawley rats, weighing 195-250 g, were divided into four groups: control, MTX treatment alone, MTX plus CVR and MTX plus PMG. A sing...
