| 摘 要： | 大剂量甲氨蝶呤治疗儿童急性淋巴细胞白血病的疗效及不良反应具有明显的个体差异。大剂量甲氨蝶呤治疗反应的多样性与甲氨蝶呤相关转运蛋白如溶脂载体转运蛋白、ABC转运蛋白以及甲氨蝶呤代谢相关酶如亚甲基四氢叶酸还原酶、二氢叶酸还原酶、胸腺嘧啶核苷酸合成酶、氨基咪唑胺甲酰转移酶等密切相关。本文就甲氨蝶呤代谢途径,甲氨蝶呤转运蛋白及代谢酶基因多态性对其疗效、不良反应的影响作一综述。

| Abstract: | The efficacy and toxicity of high-dose methotrexate(MTX)in the treatment of children with acute lymphoblastic leukemia(AML)show significant individual differences.Recent studies have found that the diversity of high-dose MTX treatment response is closely correlated with MTX-related transporters as solute carrier transporter and ABC transporter,as well as MTX metabolizing-related enzymes as methylenetetrahydrofolat reductase,dihydrofolate reductase,thymidylate synthase,and aminoimidazole carboxamide tibonucleotide transformylase.This paper reviews the research progress of the metabolizing pathway of MTX,as well as the influences of MTX-related transporters and metabolizing enzyme gene polymorphism on the efficacy and toxicity. |
