  Biotransformation of the Mycotoxin, Zearalenone, to a Non-estrogenic Compound by a Fungal Strain ofClonostachyssp.

  摘要：

  Zearalenone（玉米赤霉烯酮）是一种具有雌激素活性的真菌毒素，由一个间苯二酚部分与一个14元大环内酯环融合而成，由多种镰刀菌属物种产生。我们发现，Clonostachys rosea IFO 7063能够有效地将玉米赤霉烯酮（1）转化为断裂产物（2），即1-(3,5-二羟基苯基)-10′-羟基-1′E-十一碳烯-6′-酮。此外，断裂产物2在人乳腺癌MCF-7细胞增殖试验中并未表现出与1及17β-雌二醇相似的强雌激素活性。

  Zearalenone (ZEN)-degrading enzymes are a promising strategy to counteract the negative effects of this mycotoxin in livestock. The reaction products of such enzymes need to be thoroughly characterized before technological application as a feed additive can be envisaged. Here, we evaluated the estrogenic activity of the metabolites hydrolyzed zearalenone (HZEN) and decarboxylated hydrolyzed zearalenone

  玉米赤霉烯酮（ZEN）降解酶是一种有前景的策略，可以抵消这种霉菌毒素对家畜的负面影响。在可以设想作为饲料添加剂的技术应用之前，需要彻底表征此类酶的反应产物。在这里，我们评估了由玉米赤霉烯酮-内酰胺酶Zhd101p水解ZEN形成的代谢产物水解玉米赤霉烯酮（HZEN）和脱羧水解玉米赤霉烯酮（DHZEN）的雌激素活性。ZEN，HZEN和DHZEN在两个体外模型中进行了测试：MCF-7细胞增殖测定（0.01-500 nM）和雌激素敏感性酵母生物测定（1-10,000 nM）。此外，我们比较了饮食中ZEN的影响（4。58 mg / kg）和等摩尔日粮浓度的HZEN和DHZEN对雌性仔猪的生殖道形态以及子宫mRNA和microRNA表达的影响（n = 6，暴露4周）。尽管ZEN增加了细胞增殖和报告基因的转录，但HZEN和DHZEN均未引发雌激素反应，这表明这些代谢产物的体外雌激素水平至少比ZEN低50-10
