概括

这项研究探讨了患有酒精使用障碍 (AUD) 和高热量摄入量的小鼠的代谢变化,确定了酒精偏好和成的潜在生物标志物. 这项研究强调了这种新的MetALD模型中改变的肠道微生物组和神经炎症.

科学领域:

代谢功能障碍代谢功能障碍
酒精使用障碍 (AUD)
肝脏疾病是一种肝脏疾病.

背景情况:

酒精使用障碍 (AUD) 带来了重大的公共卫生挑战,其全球流行率和代谢后果日益增加.
现有的模型不充分代表AUD,特别是当与过多的热量摄入相结合时.
与增加的酒精摄入量相关的代谢功能障碍脂肪性肝病 (MetALD) 是一个最近特征性的疾病,区分与酒精有关的肝脏问题.

研究的目的:

在MetALD.的小鼠模型中研究代谢表型和基因表达变化.
根据酒精偏好区分代谢特征,使用血液中脂乙醇水平和消费数据.
在MetALD.中识别与酒精偏好相关的潜在分子生物标志物.

主要方法:

在13周内,小鼠接受了高脂肪和饮食,其中含有10%的乙醇 (EtOH).
在大脑,肝脏,骨肌肉,骨髓和白色脂肪组织上进行了mRNA测序.
用16S测序评估了肠道微生物群的多样性.

主要成果:

偏爱酒精的小鼠显示葡萄糖的减少,但在脂质不良症或肝硬化症中没有显著差异.
肠道微生物群多样性的减少,Wnt信号传递,以及急性阶段反应基因的升高,都在结核中观察到.
分别在大脑和肝脏中减少了Wnt和Hippo信号,同时增加了神经炎症和脂肪线粒体翻译. 特定的基因表达变化 (Nek3, Ntf3, Cux1, Irf6) 被确定为潜在的生物标志物.

结论:

开发的MetALD小鼠模型有助于未来对干预策略的研究.
该研究确定了酒精偏好的潜在生物标志物,为了解AUD提供了新的途径.
这项研究有助于区分酒精摄入和高热量饮食的代谢后果.

关键词:

这就是ALD.在 AUD 中,AUD 是 AUD.在HFD中,HFD是指HFD.在MetALD中,我们可以使用MetALD.转录组 (transcriptome) 是一个转录组.

Cell Specific Gene Expression

Cell Specific Gene Expression

Multicellular organisms contain a variety of structurally and functionally distinct cell types, but the DNA in all the cells originated from the same parent cells. The differences in the cells can be attributed to the differential gene expression. Liver cells, whose functions include detoxification of blood, production of bile to metabolize fats, and synthesis of proteins essential for metabolism, must express a specific set of genes to perform their functions. Gene expression also varies with...

Mass Spectrometry: Alcohol Fragmentation

Mass Spectrometry: Alcohol Fragmentation

Alcohols (R-OH) ionize to lose one non-bonded electron from the oxygen atom, forming molecular ions. Due to their tendency to fragment rapidly, the intensity of the molecular ion peak in the mass spectrum is weak or sometimes absent. The fragmentation patterns for alcohols occur in two ways, i.e. ⍺-cleavage and dehydration. During ⍺-cleavage, the bond at the ⍺-position adjacent to the hydroxyl group cleaves to give a resonance-stabilized cation and a radical. However, intramolecular...
