Parenteral nutrition-associated liver disease (PNALD) is a liver dysfunction caused by various risk factors presented in patients receiving total parenteral nutrition (TPN). Omega-6 rich Intralipid® and omega-3 rich Omegaven® are two intravenous lipid emulsions used in TPN. TPN could affect the hepatic expression of genes in anti-oxidative stress, but it's unknown whether TPN affects genes in drug metabolism. In this study, either Intralipid®- or Omegaven®-based TPN was administered to mice and the expression of a cohort of genes involved in anti-oxidative stress or drug metabolism was analyzed, glutathione (GSH) levels were measured, and protein levels for two key drug metabolism genes were determined. Overall, the expression of most genes was downregulated by Intralipid®-based TPN (Gstp1, Gstm1, 3, 6, Nqo1, Ho-1, Mt-1, Gclc, Gclm, Cyp2d9, 2f2, 2b10, and 3a11). Omegaven® showed similar results as Intralipid® except for preserving the expression of Gstm1 and Cyp3a11, and increasing Ho-1. Total GSH levels were decreased by Intralipid®, but increased by Omegaven®. CYP3A11 protein levels were increased by Omegaven®. In conclusion, TPN reduced the expression of many genes involved in anti-oxidative stress and drug metabolism in mice. However, Omegaven® preserved expression of Cyp3a11, suggesting another beneficial effect of Omegaven® in protecting liver functions.

全肠外营养对小鼠药物代谢基因表达的影响。

肠外营养相关肝病(PNALD)是由接受全肠外营养(TPN)的患者出现的各种危险因素引起的肝功能障碍。富含 Omega-6 的 Intralipid® 和富含 Omega-3 的 Omegaven® 是 TPN 中使用的两种静脉内脂质乳剂。TPN可影响肝脏抗氧化应激基因的表达,但TPN是否影响药物代谢基因尚不清楚。在这项研究中,对小鼠施用基于 Intralipid® 或 Omegaven® 的 TPN,分析了一组参与抗氧化应激或药物代谢的基因的表达,测量了谷胱甘肽 (GSH) 水平,以及蛋白质水平确定了两个关键的药物代谢基因。总体而言,大多数基因的表达被基于 Intralipid® 的 TPN(Gstp1、Gstm1、3、6、Nqo1、Ho-1、Mt-1、Gclc、Gclm、Cyp2d9、2f2、2b10 和 3a11)。除了保留 Gstm1 和 Cyp3a11 的表达并增加 Ho-1 外,Omegaven® 显示出与 Intralipid® 相似的结果。Intralipid® 降低了总 GSH 水平,但 Omegaven® 提高了总 GSH 水平。Omegaven® 增加了 CYP3A11 蛋白水平。总之,TPN降低了许多与小鼠抗氧化应激和药物代谢有关的基因的表达。然而,Omegaven® 保留了 Cyp3a11 的表达,表明 Omegaven® 在保护肝功能方面的另一个有益作用。TPN 降低了许多参与小鼠抗氧化应激和药物代谢的基因的表达。然而,Omegaven® 保留了 Cyp3a11 的表达,表明 Omegaven® 在保护肝功能方面的另一个有益作用。TPN 降低了许多参与小鼠抗氧化应激和药物代谢的基因的表达。然而,Omegaven® 保留了 Cyp3a11 的表达,表明 Omegaven® 在保护肝功能方面的另一个有益作用。
