摘要:

旨在研究全价粮添加红景天苷对犬血液和肝转录组学的影响,以期为犬的肝养护及肝疾病预防工作提供试验数据支持。选取10只成年中华田园犬(平均体重8.67±1.00 kg),随机分为对照组(n=5)和试验组(n=5),分别饲喂对照犬粮和红景天苷全价粮。通过血液检查来评估红景天苷全价粮的饲喂效果和安全性,并通过转录组学技术探究红景天苷全价粮对犬潜在的调节机制,试验期为8周。血液检查结果显示,红景天苷全价粮显著降低了犬血清谷丙转氨酶的浓度(P<0.05),对其他大部分指标没有显著影响(P>0.05),但相比于对照犬粮,采食红景天苷全价粮的犬血液指标波动小,能保持血液指标的稳定。转录组学分析结果显示,差异表达基因显著富集在钙信号通路、PI3K-Akt信号通路和MAPK信号通路等。针对表型的基因集富集分析结果表明,红景天苷全价粮在脂代谢、糖代谢、炎症、氧化应激和纤维化方面起调节作用,其中对于糖脂代谢的调节更显著,相关信号通路在试验组显著上调。综上所述,红景天苷全价粮具有降低犬血清谷丙转氨酶浓度的作用,能够稳定犬的血液指标浓度,调节了犬的肝糖脂代谢,这可能主要通过调节钙信号通路、PI3K-Akt信号通路和MAPK信号通路来实现。

Abstract:

The aim of this study was to investigate the effects of salidroside-added complete nutrition food on blood and liver transcriptomics in dogs, with a view to provide experimental data to support liver conservation and prevent liver disease in dogs. Ten adult Chinese field dogs (8.67±1.00 kg) were selected and randomly divided into control (n=5) and test (n=5) groups. The control group was fed with control food, while the test group was fed with complete nutrition food supplemented with salidroside. The study evaluated the feeding effect and safety of complete nutrition food supplemented with salidroside through blood examination. Additionally, the potential regulatory mechanism of salidroside-added complete nutrition food on dogs was explored using transcriptomics technology. The trial period lasted 8 weeks. The blood test results showed that salidroside-added complete nutrition food significantly reduced the concentration of serum alanine aminotransferase in dogs (P < 0.05), and did not significantly affect most of the other indexes (P>0.05). However, compared to the control food, the complete nutrition food with added salidroside did not cause greater fluctuations in blood indexes and could maintain their stability. The transcriptomics analysis results revealed that differentially expressed genes were significantly enriched in the calcium signaling pathway, PI3K-Akt signaling pathway, and MAPK signaling pathway. The results of gene set enrichment analysis for phenotypes revealed that salidroside-added complete nutrition food played a regulatory role in lipid metabolism, glucose metabolism, inflammation, oxidative stress, and fibrosis. It showed a more significant regulation of glucose and lipid metabolism, with the related signaling pathways significantly up-regulated in the test group. In conclusion, salidroside-added complete nutrition food has been found to reduce serum alanine aminotransferase concentration in dogs and help stabilize the concentration of blood indexes in dogs, and regulate hepatic glucolipid metabolism in dogs. These effects may be primarily achieved by regulating the calcium signaling pathway, the PI3K-Akt signaling pathway, and the MAPK signaling pathway.
