| 摘 要： | 为探讨硫代乙酰胺(TAA)诱导草鱼肝胰脏损伤与损伤修复的作用机制, 试验以腹腔注射硫代乙酰胺诱导肝胰脏损伤实验模型草鱼为对象, 分别饲喂含有酵母培养物dv、姜黄素和水飞蓟素的饲料70 d后, 采集草鱼肝胰脏样品, 采用实时定量反转录聚合酶链式反应(qPCR)方法, 检测了草鱼肝胰脏脂肪酸合成酶(FAS)、过氧化物酶增殖体激活受体γ辅助激活因子(PGC1-α)、硬脂酰辅酶A去饱和酶1(SCD1)、解偶联蛋白2(UCP2)、过氧化物酶增殖体激活受体α(PPAR-α)、过氧化物酶增殖体激活受体γ(PPAR-γ)、类胰岛素样生长因子 (IGF-Ⅰ)的mRNA丰度, 探讨在饲料中添加酵母培养物dv、姜黄素和水飞蓟素后, 草鱼肝胰脏脂代谢相关基因表达丰度的变化。结果显示, TAA诱导草鱼肝损伤后, FAS基因表达丰度上调, 调控脂质分解代谢的上游基因(如PPAR-α、ΡΡΑR-γ、PGC1-α)表达丰度没有显著性的变化, 而SCD1基因表达丰度显著性下调, 其结果可能导致脂质在肝细胞积累量增加, 诱发脂肪性肝病的发生和发展。在饲料中添加酵母培养物dv、姜黄素和水飞蓟素后, 在一定程度上修复了TAA对肝胰脏脂代谢的损伤。 |
| 关 键 词： | 草鱼 损伤 脂代谢 表达丰度 |
