RNA-Seq experiment of primary hepatic stellate cells (HSCs) and LX-2 cell line treated with TGFb

Project description:Liver fibrosis stands as the most prominent predictor of overall mortality in non-alcoholic steatohepatitis (NASH). The fibrotic liver features excessive deposition of extracellular matrix (ECM), primarily produced from "activated" hepatic stellate cells (HSCs). Whereas targeting HSC in fibrosis therapeutics shows promise, the current identification of human genetic regulators driving HSC activation is far from complete. This knowledge gap largely emanates from the limited understanding of the vast array of long non-coding RNAs (lncRNAs). Analyzing differentially regulated human lncRNAs under various regulatory patterns often provides the most practical means to inform their function. To get human lncRNA regulators in driving HSC activation, we cultured both primary human stellate cells and LX-2 cells. Then, we treated them with TGFb to mimic the activation process in vitro. Differentially expressed lncRNAs can be obtained from RNAseq results, which may guide the characterization of lncRNAs relevant to HSC activation.

Human hepatic stellate cell line LX-2 activated under acidic culture condition

Project description:We found that the number of tumor-infiltrating myofibroblasts was positively correlated to tumor acidification status in hepatocellular carcinoma (HCC). Hepatic stellate cells (HSCs), the predominant precursors of liver myofibroblasts, were activated and transdifferentiated into myofibroblasts under acidic culture condition. To identify the molecular phenotype of LX-2 cells in acidic culture conditions, we further conducted a gene expression profile analysis. LX-2 cells cultured in pH 7.2 or pH 6.2 medium separately for six days was used in gene expression microarray analysis.

MicroRNA expression profile of human hepatic stellate cells LX-2 co-cultured with human umbilical cord mesenchymal stem cells and control group

Project description:Hepatic stellate cells(HSCs) are the main effector cells of liver fibrosis. In order to study the effect of mesenchymal stem cells(MSCs) on microRNAs expression of HSCs, we co-cultured HSCs LX-2 activated by TGFβ1 with human umbilical cord MSCs(hUC-MSCs) for 48 hours, and compared the differentially expressed miRNA with LX-2 cultured alone by high-throughput sequencing. The results showed that two mature microRNAs expressed increased, and nine expressed decreased.

Effect of depletion of ADAMTS12 on gene expression in the LX-2 cell line derived from activated human hepatic stellate cells (HSCs)

Project description:Activated HSCs are liver stromal cells that play an important rôle in tissue repair and fibrosis. We performed gene expression profiling analysis using data obtained from RNA-seq of LX-2 cells treated for 48h with control siRNAs (siCTL) or siRNAs specific for ADAMTS12 (siADAMTS12)

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.

Expression data from the hepatic stellate cell line LX-2 after treatment with DMOG and from the liver sinusoidal endothelial cell line TRP3 after incubation with conditioned medium of DMOG-treated LX-2

Project description:Expression data from the hepatic stellate cell line LX-2 after treatment with the prolylhydroxylase inhibitor dimethyloxalylglycine (DMOG) and from the liver sinusoidal endothelial cell line TRP3 after incubation with conditioned medium of DMOG-treated LX-2 Prolyl-hydroxylase inhibitors such as dimethyloxalylglycine (DMOG) stabilize HIF-1α, thereby chemically inducing hypoxia, which also accelerates liver volume increase when given with portal rerouting. We used microarrays to clarify the cellular crosstalk of the different cell types in accelerated liver regeneration by examining the role of hepatic stellate cells (HSC) and liver sinusoidal endothelial cells (LSEC).

Investigating the Antifibrotic Effects of β-Citronellol on a TGF-β1-stimulated LX-2 Hepatic Stellate Cell Model

Project description:Liver fibrosis, a consequence of chronic liver damage or inflammation, is characterized by the excessive buildup of extracellular matrix components. This progressive condition significantly raises the risk of severe liver diseases like cirrhosis and hepatocellular carcinoma. The lack of approved therapeutics underscores the urgent need for novel anti-fibrotic drugs. Hepatic stellate cells (HSCs), key players in fibrogenesis, are promising targets for drug discovery. This study investigated the anti-fibrotic potential of Citrus hystrix DC. (KL) and its bioactive compound, β-citronellol (β-CIT), in a human HSC cell line (LX-2). Cells exposed to TGF-β1 to induce fibro-genesis were co-treated with crude KL extract and β-CIT. Gene expression was analyzed by Re-al-Time qRT-PCR to assess fibrosis-associated genes (ACTA2, COL1A1, TIMP1, SMAD2). The re-leasing of matrix metalloproteinase 9 (MMP-9) was measured by ELISA. Proteomic analysis and molecular docking identified potential signaling proteins and modeled protein-ligand interac-tions. Results showed that both crude KL extract and β-CIT suppressed HSC activation genes and MMP-9 levels. The MAPK signaling pathway emerged as a potential target of β-CIT. This study demonstrates the potential of KL extract and β-CIT to inhibit HSC activation during TGF-β1-induced fibrogenesis, suggesting the promising role of β-CIT in anti-hepatic fibrosis therapies.

In Vitro Investigation of The Anti-Fibrotic Potential of 1-Phenyl-2-Pentanol, Identified from Moringa Oleifera Lam. on Hepatic Stellate Cells

Project description:Liver fibrosis, characterized by excessive extracellular matrix deposition, is driven by activated hepatic stellate cells (HSCs). Due to the limited availability of anti-fibrotic drugs, research con-tinues to explore potential therapeutic agents. Moringa oleifera Lam. (MO), known for its various bioactive properties, is being investigated for its anti-fibrotic potential. This study focused on 1-phenyl-2-pentanol (1-PHE), a compound derived from MO leaves, and its impact on LX-2 hu-man hepatic stellate cell activation. TGF-β1-stimulated LX-2 cells were treated with MO extract or 1-PHE, and liver fibrosis markers were assessed at both gene and protein levels. Proteomic analysis and molecular docking were employed to identify potential protein targets and signaling pathways affected by 1-PHE. 1-PHE treatment downregulated fibrosis markers, including colla-gen type I alpha 1 chain (COL1A1), collagen type IV alpha 1 chain (COL4A1), mothers against decapentaplegic homolog 2 and 3 (SMAD2/3), and matrix metalloproteinase-2 (MMP2), and re-duced the secretion of matrix metalloproteinase-9 (MMP9). Proteomic analysis revealed the pos-sible mechanism of 1-PHE in modulating the Wnt/β-catenin pathway. These findings suggest that 1-PHE may suppress HSCs activation by inhibiting the TGF-β1 and Wnt/β-catenin signaling pathways, indicating its potential as an anti-liver fibrosis agent. Further research is warranted to validate these findings.
