Small RNA-Seq for primary rat hepatic stellate cells and hepatic stellate cell-derived small extracellular vesicles

ABSTRACT: Aims: To obtain small non-coding RNA expression profiles of short-term activated and long-term activated hepatic stellate cells (HSCs). To obtain small non-coding RNA expression profiles of small extracellular vesicles (sEVs) from short-term activated and long-term activated HSCs. Methods: Primary rat HSCs were isolated and cultured in vitro. To isolate HSC-derived sEVs, culture media (CMs) from Day 0 to Day 3 and Day 7 to Day 14 were collected. The sEVs from Day 0 to Day 3 HSC CMs were referred to as short-term activated HSC-sEVs (3dHSC-sEVs), and those from Day 7 to Day 14 HSC CMs were referred to as long-term activated HSC-sEVs (14dHSC-sEVs). Day 3 HSCs, Day 14 HSCs, and HSC-sEVs were collected and lysed in TRIzol (Life Technologies) for RNA sample preparation at the indicated time points.

Human hepatic stellate cell-derived extracellular vesicles LC-MSMS

Project description:Activation and migration of hepatic stellate cells (HSCs) followed by matrix deposition are characteristics of liver fibrosis. Several studies have shown the importance of hepatocyte and endothelial cell-derived extracellular vesicles (EVs) in liver pathobiology. However, less is known about the role of HSC-derived EVs in liver diseases. In this study, we investigated the molecules released through HSC-derived EVs and whether these can promote fibrosis.

SILAC-based Quantitative Proteomic Analysis of Secretome between Activated and Reverted Hepatic Stellate Cells

Project description:Activated hepatic stellate cell (HSC) is the main myofibroblast cell in the liver fibrosis(LF). An important characteristic of the recovery of LF is not only the apoptosis of activated HSCs but also reversal of myofibroblast-like phenotype to a quiescent-like phenotype. Understanding the changes of secreted proteins in the reversion of activated HSCs may provide the broader view of cellular regulatory networks and discover candidate markers or targets for therapeutic strategies of LF. In this study, stable isotope labeling with amino acids (SILAC) combining with LTQ-FT mass spectrometer were performed on in vitro activated HSCs and reverted HSCs to obtain a proteomic view of secretory proteins. In total, 330 proteins showed significant differences in reverted HSCs. Among these, 109 up-regulated proteins were mainly involved in amino acid metabolism pathway and glucose metabolism pathway using GeneGO/MetaCore software, while 221 down-regulated proteins are closely associated with HSCs activation, such as cytoskeleton remodeling, chemokines and cell adhesion. Additionally, a set of novel proteins associated with HSCs activation and reversion were validated by Western blotting in the cell secretion and in the sera of LF, including Vitronectin, laminin beta 1(LAMB1) and Ubiquitin conjugation factor E4B(UBE4B). Our study provided the valuable insight into the mechanisms in the reversion of activated HSCs and identified some potential biomarkers of LF in clinical studies.

Glycolysis in hepatic stellate cells coordinates fibrogenic extracellular vesicle release spatially to amplify liver fibrosis

Project description:Liver fibrosis is characterized by the activation of perivascular hepatic stellate cells (HSCs), the release of fibrogenic nano-sized extracellular vesicles (EVs) and increased HSC glycolysis. Nevertheless, how glycolysis in HSCs coordinates fibrosis amplification through tissue zone-specific pathways remains elusive. Here, we demonstrate that HSC-specific genetic inhibition of glycolysis reduced liver fibrosis. Moreover, spatial transcriptomics revealed a fibrosis-mediated upregulation of EV-related pathways in the liver pericentral zone, which was abrogated by the glycolysis genetic inhibition. Mechanistically, glycolysis in HSCs upregulated the expression of EV-related genes such as RAB31 by enhancing histone-3-lysine-9 acetylation on the promoter region, which increased EV release. Functionally, these glycolysis-dependent EVs increased fibrotic gene expression in recipient HSC. Furthermore, EVs derived from glycolysis-deficient mice abrogated liver fibrosis amplification in contrast to glycolysis-competent mouse EVs. In summary, glycolysis in HSCs amplifies liver fibrosis by promoting fibrogenic EV release in the hepatic pericentral zone, which represents a potential therapeutic target.

Integrative gene expression profiling analysis of human quiescent hepatic stellate cells

Project description:Unveiling the regulatory pathways maintaining hepatic stellate cells (HSC) in a quiescent (q) phenotype is essential to develop new therapeutic strategies to treat fibrogenic diseases. To uncover the miRNA-mRNAs regulatory interactions in qHSCs, HSCs were FACS-sorted from healthy livers and activated HSCs were generated in vitro. MiRNA Taqman array analysis showed HSCs expressed a low number of miRNA, from which 46 were down-regulated and 212 up-regulated upon activation. Computational integration of miRNA and gene expression profiles revealed that 66% of qHSCs miRNAs correlated with more than 6 altered targeted mRNAs (17,28Â±10,7 targets/miRNA), whereas aHSC-associated miRNAs had an average of 1,49 targeted genes. Interestingly, interaction networks generated by miRNA-targeted genes in qHSCs were associated with key HSCs activation processes. Next, selected miRNAs were validated in healthy and cirrhotic human livers and miR-192 was chosen for functional analysis. Down-regulation of miR-192 in HSC was found to be an early event during fibrosis progression in mouse models of liver injury. Moreover, mimic assays for miR-192 in HSCs revealed its role in HSC activation, proliferation and migration. Together, these results uncover the importance of miRNAs in the maintenance of qHSC phenotype and form the basis for understanding the regulatory networks in HSCs. Transcriptomic profile derived from four quiescent hepatic stellate (QHSC), four activated hepatic stellate (AHSC), three liver sinusoidal endothelial (LSEC) and two hepatocytes cells (HEP).

Investigation of hepatic stellate cell proteomics during activa-tion with fetal bovine serum

Project description:Hepatic stellate cells (HSCs) are the major driving factor in liver fibrosis. Upon liver inflammation caused by alcohol abuse and/or a fatty liver, HSCs transform from a quiescent- into a proliferating, fibrotic phenotype. We study this transformation termed “activation”, using state of the art TIMS-TOF mass spectrometry proteomics, as well as phenotype analysis of the immortalized LX-2 HSC cell line. In our work we employ a simple, yet reliable model of HSC activation via an in-crease in growth media serum concentration (serum activation). Protein network analysis of ac-tivated LX 2 cells reveals an increase in the production of ribosomal proteins and proteins related to migration. Interestingly, we could also observe a decrease in the expression of lipogenic pro-teins and a loss of cytosolic lipid droplets during activation. Especially the downregulation of proteins associated with cholesterol biosynthesis might be a promising target for further study. This work provides an update on HSC activation characteristics using contemporary proteomic and bioinformatic analysis and presents an accessible model for HSC activation.

In vitro activation and reversion of human primary hepatic stellate cells

Project description:Liver fibrosis is characterized by the excessive formation and accumulation of matrix proteins as a result of wound healing in the liver. A main event during fibrogenesis is the activation of the liver resident quiescent hepatic stellate cell (qHSC). Recent studies suggest that reversion of the activated HSC (aHSC) phenotype into a quiescent-like phenotype could be a major cellular mechanism underlying fibrosis regression in the liver, thereby offering new therapeutic perspectives for the treatment of liver fibrosis. The goal of the present study is to identify experimental conditions that can revert the activated status of human HSCs and to map the molecular events associated with this phenotype reversion by gene expression profiling Transcriptomic profiling of primary human quiescent HSCs (qHSCs), in vitro activated HSCs (aHSCs) and in vitro reverted HSCs (rHSCs). The cell types come from different donors (This is detailed in the original manuscript.).
