作者李宜聪,廖凯,姬仁磊,方炜,徐丹,麦康森,艾庆辉（2019）在《茶多酚对大菱鲆生长、抗氧化能力及脂肪代谢相关基因表达的影响》一文中研究指出：为了研究饲料中添加茶多酚对大菱鲆生长、抗氧化能力及脂肪代谢相关基因表达的影响,以初始体质量为(13.51+0.31) g的大菱鲆幼鱼为实验对象,设计4组添加不同梯度茶多酚(0%、0.01%、0.02%和0.05%,干重添加量分别为0、100、200和500 mg/kg)的等氮等脂实验饲料,进行为期70 d的摄食生长实验。结果显示:①与对照组相比,饲料中添加0.01%～0.02%茶多酚显著提高了大菱鲆幼鱼增重率(WGR);饲料效率(FE)随饲料中茶多酚添加水平升高而升高,但各组间差异不显著;随饲料中茶多酚添加水平升高,大菱鲆肝体比(HSI)呈降低趋势,且显著低于对照组;②鱼体组成分析表明,投喂添加茶多酚饲料组大菱鲆鱼体和肝脏粗脂肪含量呈下降趋势,且在茶多酚添加水平为0.02%～0.05%时达到最低值,显著低于对照组;③与对照组相比,投喂添加茶多酚饲料组大菱鲆血清总抗氧化能力(T-AOC)及谷胱甘肽过氧化物酶(GSH-Px)活性显著升高,且各添加组间差异不显著;超氧化物歧化酶(SOD)活性随茶多酚的添加水平升高呈先升高后降低趋势,且在添加水平为0.02%时显著高于对照组;血清丙二醛(MDA)含量随茶多酚添加水平升高而降低,且在添加水平为0.02%～0.05%时显著低于对照组;④大菱鲆肝脏固醇调节元件结合蛋白1(SREBP-1)表达量随着饲料中茶多酚添加水平升高而降低,且在添加水平为0.02%～0.05%时达到最低值,显著低于对照组;脂肪酸合成酶(FAS)表达量随茶多酚添加水平的升高呈先降低后升高趋势,且在添加水平为0.02%时显著低于对照组;过氧化物酶体增殖物激活受体α(PPARα)表达量变化趋势与FAS相反,且在添加水平为0.02%时达到最高值。肉毒碱棕榈酰转移酶1(CPT1)表达量随饲料中茶多酚添加水平升高而升高,显著高于对照组,且各添加组间差异不显著。研究表明,高脂饲料中添加茶多酚能促进大菱鲆生长、降低肝脏脂肪过度沉积并提高血清抗氧化能力,高脂饲料中添加0.02%茶多酚是大菱鲆幼鱼生长的最适添加量。
