Abstract

Metal transporters, including divalent metal-ion transporter-1 (DMT1), Zrt-/Irt-like protein 8 and 14 (ZIP8 and ZIP14), and ferroportin-1 (FPN1), reportedly participate in cellular cadmium (Cd) uptake, but those in farm animals remain unclarified. This study aimed to examine the growth, plasma biochemical indices, Cd accumulation, and expression of metal transporter genes in the liver, kidney, and muscle of goats exposed to rice paddies contaminated with different levels of Cd. Twenty-four goats were randomly assigned across three dietary treatments: 0.23, 0.63, and 1.07 mg of Cd/kg of dry matter (DM) for 60 days. The results showed that dietary Cd exposure increased (p < 0.05) both Cd accumulation and the mRNA expressions of metal transporter genes (DMT1, ZIP, and FPN1) in the liver and kidney but not in the muscle, suggesting dietary Cd exhibited different deposition rates between goat liver, kidney, and muscle. These outcomes suggest that high levels of dietary Cd stimulated the expression of metal transporter genes and thereby enhanced the uptake and accumulation of Cd in the goat liver and kidney. As such, higher Cd concentrations in the liver and kidney observed with Cd diets could be partly explained by upregulation of metal transport genes expression.

摘要

据报道,包括二价金属离子转运蛋白1(DMT1)、锌铁调控转运蛋白8和14(ZIP8和ZIP14)以及铁转运蛋白1(FPN1)在内的金属转运蛋白参与细胞对镉(Cd)的摄取,但家畜体内的情况尚不清楚。本研究旨在检测暴露于不同镉污染水平稻田的山羊的生长、血浆生化指标、镉蓄积以及肝脏、肾脏和肌肉中金属转运蛋白基因的表达。将24只山羊随机分为三种日粮处理组:每千克干物质(DM)中镉含量分别为0.23、0.63和1.07毫克,持续60天。结果表明,日粮镉暴露会增加(p < 0.05)肝脏和肾脏中的镉蓄积以及金属转运蛋白基因(DMT1、ZIP和FPN1)的mRNA表达,但肌肉中没有,这表明日粮镉在山羊肝脏、肾脏和肌肉中的沉积速率不同。这些结果表明,高剂量日粮镉刺激了金属转运蛋白基因的表达,从而增强了山羊肝脏和肾脏对镉的摄取和蓄积。因此,镉日粮组在肝脏和肾脏中观察到的较高镉浓度,部分原因可能是金属转运基因表达上调。
