概括

患有慢性乙型肝炎 (CHB) 和非酒精性脂肪性肝病 (NAFLD) 的患者由于明显的肝蛋白水平变化,预后较差. 这项研究为CHB和NAFLD进展和机制提供了新的见解.

科学领域:

肝病学肝病学是一种肝病学.
代谢综合征研究代谢综合征研究
蛋白质组学是指蛋白质组学.

背景情况:

非酒精性脂肪性肝病 (NAFLD) 的患病率在慢性乙型肝炎 (CHB) 患者中正在上升,与肥胖和代谢综合征有关.
无论是NAFLD还是CHB都可以独立导致肝纤维化和肝细胞癌.
同时发生的CHB和NAFLD的发病因子尚未完全理解.

研究的目的:

调查同时患有CHB和NAFLD的患者的分子机制和蛋白质表达模式.
为了将这些模式与单独的CHB或NAFLD进行比较.
了解对预后的临床影响.

主要方法:

来自四组肝脏组织的蛋白质组分析:健康对照组,CHB,NAFLD和CHB+NAFLD患者.
对差异表达蛋白质 (DEP) 的生物信息学分析.
在患者样本和小鼠模型中验证选择的DEP.

主要成果:

在CHB患者中同时出现的NAFLD可能通过炎症和代谢通路激活来增强病毒清除.
肝硬化症的严重程度与脂肪酸降解和糖解/葡萄糖生成的中断有关.
改变的蛋白质水平 (例如,ACAT1,SERPINB3,LRP6) 与CHB+NAFLD患者的严重预后有关.

结论:

与单独的CHB或NAFLD相比,由NAFLD复杂化的CHB的预后不太好.
独特的肝蛋白表达模式区分了并发性CHB和NAFLD.
这项研究为疾病进展和CHB和NAFLD的临床机制提供了新的见解.

Proteomics

Proteomics

A proteome is the entire set of proteins that a cell type produces. We can study proteomes using the knowledge of genomes because genes code for mRNAs, and the mRNAs encode proteins. Although mRNA analysis is a step in the right direction, not all mRNAs are translated into proteins.
Proteomics is the study of proteomes' function. It involves the large-scale systematic study of the proteome to denote the protein complement expressed by a genome. Scientist Mark Wilkins coined the term...
