As one of the key-enzymes in folic acid metabolic pathway, Folylpolyglutamate synthetase (FPGS) content and activity directly associated with the effects of MTX.
背景:氨甲蝶呤(Methotrexate,MTX)是许多叶酸途径抗肿瘤药物的前体,存在L-(+)-MTX和D-(-)-MTX 2种形式的对映体,广泛应用于淋巴瘤、急性白血病和肺癌等多种肿瘤的治疗,作为MTX代谢途径中的关键酶之一的细胞内叶酰聚谷氨酸合成酶(folylpolyglutamate synthetase,FPGS),其含量和活性直接与MTX作用效果相关,已成为当今研究的热点,但有关FPGS定量检测的报道甚少。

Studies were carried out on influences of replacement of 25% NO~-_3-N with NH~+_4-N in nutrient solution(enhanced ammonium nutrition) on tomato growth and activity of such key enzymes in N assimilation and organic acids as nitrate reductase(NR),glutamine synthetase(GS)and phosphoenolpyruvate carboxylase(PEPcase)in tomato leaves and fruits sampled at different developmental stages.
采用砂培实验研究NH4+-N部分代替NO3--N对番茄的影响,结果表明:与全硝处理(100%NO3-)相比较,增铵处理(NH4+∶NO3-=25%∶75%)下番茄鲜果重显著提高;同时叶片内NO3--N含量随增铵而显著降低,叶片与果实内NH4+-N含量及果实的可溶性蛋白含量随增铵而升高;增铵条件抑制了叶片和果实的硝酸还原酶(NR)活性,提高了叶片和果实的磷酸烯醇式丙酮酸羧化酶(PEPcase)活性及叶片谷氨酰胺合成酶(GS)活性,但对果实的谷氨酰胺合成酶(GS)活性影响不大。
