尽管非酒精性脂肪性肝炎(NASH)的发病率随着生活方式相关疾病(如代谢综合征)的增加而增加,但对炎症和纤维化发生前肝脏蛋白质组的变化知之甚少。在这里,我们通过2D-DIGE和nano-HPLC-MS/MS研究了喂食NASH诱导饮食的雌性C57 BL/6 N小鼠的肝可溶性蛋白质组的早期变化。同时,进行了组织学和甘油三酯,胆固醇和蛋氨酸循环中间产物的肝脏含量测量。肝脏脂肪变性在喂养2天后表现出来,尽管在没有炎症或纤维化体征的情况下,肝脏可溶性蛋白质组的显著变化在第10天之前不明显。蛋白质组学改变主要影响能量和氨基酸代谢、解毒过程、尿素循环和一碳/S-腺苷甲硫氨酸途径。此外,从肝组织中定量了相关受影响途径的中间体,证实了蛋白质组学分析的结果。
Despite the increasing incidence of nonalcoholic steatohepatitis (NASH) with the rise in lifestyle‐related diseases such as the metabolic syndrome, little is known about the changes in the liver proteome that precede the onset of inflammation and fibrosis. Here, we investigated early changes in the liver‐soluble proteome of female C57BL/6N mice fed an NASH‐inducing diet by 2D‐DIGE and nano‐HPLC‐MS/MS. In parallel, histology and measurements of hepatic content of triglycerides, cholesterol and intermediates of the methionine cycle were performed. Hepatic steatosis manifested itself after 2 days of feeding, albeit significant changes in the liver‐soluble proteome were not evident before day 10 in the absence of inflammatory or fibrotic signs. Proteomic alterations affected mainly energy and amino acid metabolism, detoxification processes, urea cycle, and the one‐carbon/S‐adenosylmethionine pathways. Additionally, intermediates of relevant affected pathways were quantified from liver tissue, confirming the findings from the proteomic analysis.
