| 1 | Decoding the role of extracellular vesicles in liver diseases显示文摘Cell-to-cell communication is a fascinating process that is essential for maintaining tissue and wholebody homeostasis.Extracellular vesicles(EVs)are cell-derived membrane-bound nanoparticles that are a means of communication between cells.Accumulating evidence indicates that EVs can render either beneficial or harmful outcomes,depending on the specific cargos(e.g.,proteins,lipids,RNAs)transferred between cells.EVs also have great value as diagnostic and prognostic markers of disease because they are present in a variety of biological fluids and carry bioactive molecules from their cells or tissues of origin.Liver cells can both release and receive EVs derived from other cells and emerging evidence indicates that liver EVs play important roles in the pathogenesis of various liver diseases,including liver cancer,viral hepatitis,non-alcoholic fatty liver disease,and alcoholic liver disease.This review provides an overview of the biogenesis and secretion of EVs and summarizes the most recent advances in understanding the role of EVs in liver physiology and diseases.Additionally,we discuss potential applications of liver EVs as biomarkers and in therapeutic approaches to treat liver diseases. | Fengyan Deng Nancy Magee Yuxia Zhang | 2017 | Liver Research2017，1，3： | 1 |
| 2 | Hepatic transcriptome profiling reveals early signatures associated with disease transition from non-alcoholic steatosis to steatohepatitis显示文摘Background and aim:Non-alcoholic fatty liver disease(NAFLD)is becoming a leading cause of chronic liver disease worldwide.The molecular events that influence disease progression from non-alcoholic fatty liver(NAFL)to aggressive non-alcoholic steatohepatitis(NASH)remain incompletely understood,leading to lack of mechanism-based targeted treatment options for NASH.This study aims to identify early signatures associated with disease progression from NAFL to NASH in mice and humans.Materials and methods:Male C57BL/6J mice were fed a high-fat,-cholesterol,and-fructose(HFCF)diet for up to 9 months.The extent of steatosis,inflammation,and fibrosis was evaluated in liver tissues.Total RNA sequencing(RNA-seq)was conducted to determine liver transcriptomic changes.Results:After being fed the HFCF diet,mice sequentially developed steatosis,early steatohepatitis,steatohepatitis with fibrosis,and eventually spontaneous liver tumor.Hepatic RNA-seq revealed that the key signatures during steatosis progression to early steatohepatitis were pathways related to extracel-lular matrix organization and immune responses such as T cell migration,arginine biosynthesis,C-type lectin receptor signaling,and cytokine-cytokine receptor interaction.Genes regulated by transcription factors forkhead box M1(FOXM1)and negative elongation factor complex member E(NELFE)were significantly altered during disease progression.This phenomenon was also observed in patients with NASH. | Nancy Magee Forkan Ahamed Natalie Eppler Elizabeth Jones Priyanka Ghosh Lily He Yuxia Zhang | 2022 | Liver Research2022，6，4： | 0 |
