Project description:Alcoholic liver disease (ALD) is a leading cause of cirrhosis in the United States, which is characterized by extensive deposition of extracellular matrix proteins (ECM) and formation of a fibrous scar. Hepatic Stellate Cells (HSCs) are the major source of Collagen Type I producing myofibroblasts in ALD fibrosis. However, the mechanism of alcohol-induced activation of human and mouse HSCs is not fully understood. We compared the gene expression profiles of primary cultured human HSCs (hHSCs) isolated from patients with ALD (n=3) or without underlying liver disease (n=4) using RNA-Seq analysis. Furthermore, the gene expression profile of ALD hHSCs was compared to that of alcohol-activated mHSCs (isolated from intragastric (IG) alcohol-fed mice), or carbon-tetrachloride (CCl4)-activated mouse HSCs (mHSCs). Comparative transcriptome analysis revealed that ALD hHSCs, and alcohol- and CCl4-activated mHSCs share the expression of common HSC activation (Col1a1, Acta1, PAI-1, TIMP1, LOXL2), indicating that a common mechanism underlies activation of human and mouse HSCs. Furthermore, alcohol-activated mHSCs most closely recapitulate the gene expression profile of ALD hHSCs. We identified the genes that are similarly and uniquely upregulated in primary cultured alcohol-activated hHSCs and freshly isolated mHSCs, which include CSF1R, PLEK, LAPTM5, CD74, CD53, MMP9, CD14, CTSS, TYROBP, ITGB2, and other genes (compared to CCl4-activated mHSCs). We identified genes in alcohol-activated mHSCs from IG alcohol-fed mice that are largely consistent with the gene expression profile of primary cultured hHSCs from ALD patients. These genes are unique to alcohol-induced HSC activation in two species, and therefore, may become new targets or readout for anti-fibrotic therapy in experimental models of ALD.

Project description:Hepatic stellate cells are involved in the development of hepatic fibrosis. We here perform transcriptional profiling of hepatic stellate cells (HSCs) isolated from Western diet/high fructose-fed C57BL6/J mice, carbon tretrachloride (CCl4)-treated C57BL6/J mice, and of murine HSCs differentiated in vitro. Specifically, gene expression profiles are obtained from hepatic stellate cells isolated from C57BL6 mice fed a Western Diet supplemented with high fructose for 12, 16 or 24 weeks or normal chow. From hepatic stellate cells isolated from C57BL6 mice treated CCl4 for 1, 4 or 8 weeks or treated with vehicle. From hepatic stellate cells isolated from healthy C57BL6 mice and seeded on normal plastic cell culture dishes for 1, 4, 8, or 12 days. And from hepatic stellate cells isolated from healthy C57BL6 mice and seeded on normal plastic cell culture dishes for 6 days in the presence of 10uM U0126 or DMSO.

Hepatic stellate cells (HSCs) are the major source of collagen type 1 producing myofibroblasts in ALD fibrosis. However, the mechanism of alcohol-induced activation of human and mouse HSCs is not fully understood. We compared the gene-expression profiles of primary cultured human HSCs (hHSCs) isolated from patients with ALD (n = 3) or without underlying liver disease (n = 4) using RNA-sequencing analysis. Furthermore, the gene-expression profile of ALD hHSCs was compared with that of alcohol-activated mHSCs (isolated from intragastric alcohol-fed mice) or CCl4-activated mouse HSCs (mHSCs). Comparative transcriptome analysis revealed that ALD hHSCs, in addition to alcohol-activated and CCl4-activated mHSCs, share the expression of common HSC activation (Col1a1 [collagen type I alpha 1 chain], Acta1 [actin alpha 1, skeletal muscle], PAI1 [plasminogen activator inhibitor-1], TIMP1 [tissue inhibitor of metalloproteinase 1], and LOXL2 [lysyl oxidase homolog 2]), indicating that a common mechanism underlies the activation of human and mouse HSCs. Furthermore, alcohol-activated mHSCs most closely recapitulate the gene-expression profile of ALD hHSCs. We identified the genes that are similarly and uniquely up-regulated in primary cultured alcohol-activated hHSCs and freshly isolated mHSCs, which include CSF1R (macrophage colony-stimulating factor 1 receptor), PLEK (pleckstrin), LAPTM5 (lysosmal-associated transmembrane protein 5), CD74 (class I transactivator, the invariant chain), CD53, MMP9 (matrix metallopeptidase 9), CD14, CTSS (cathepsin S), TYROBP (TYRO protein tyrosine kinase-binding protein), and ITGB2 (integrin beta-2), and other genes (compared with CCl4-activated mHSCs). Conclusion: We identified genes in alcohol-activated mHSCs from intragastric alcohol-fed mice that are largely consistent with the gene-expression profile of primary cultured hHSCs from patients with ALD. These genes are unique to alcohol-induced HSC activation in two species, and therefore may become targets or readout for antifibrotic therapy in experimental models of ALD.

Project description:Hepatic stellate cells (HSCs) experience phenotypic transformation, from the quiescent phenotype to the activated one, after different etiologies of liver injury. Liver fibrosis is then occurred upon the activation of HSCs. miR-16 deficiency is identified to be an important characteristic of HSCs activation. We used Affymetrix rat 230 2.0 arrays (Affymetrix, Santa Clara, U.S.A.) to uncover the global alternations of transcriptome under miR-16 restoration. We isolated quiescent hepatic stellate cells (HSCs) from adult male SD rats (normal control group) by in situ perfusion and density-gradient centrifugation. Activated HSCs were separated from rats of fibrosis model group, which were treated by 40% carbon tetrachloride (CCl4) for 8 weeks, by means of liver section, digestion and sequential centrifugation. Quiescent and activated HSCs were then divided into 4 groups at random, namely quiescent HSCs, activated HSCs, pLV-miR-16-treated HSCs and pLV-GFP-treated HSCs. The pLV-miR-16-treated group, pLV-GFP-treated group were infected with pLV-miR-16 and pLV-GFP, respectively.

Project description:Hepatic stellate cells (HSCs) exert a central pathogenic role in the development of liver fibrosis. However, the fibrosis-independent and homeostatic functions of these specialized liver pericytes remain poorly understood. Here, we demonstrate that genetic depletion of HSCs alters Wnt target gene expression in hepatocytes and liver zonation, leading to profound alterations of regeneration, cytochrome P450 metabolism and injury. HSC-selective deletion of Rspondin-3, a modulator of Wnt signalling with high enrichment in HSCs, phenocopies the effects of HSC depletion on hepatocyte gene expression, zonation, regeneration and cytochrome P450-mediated detoxification and increases alcohol-associated and metabolic dysfunction-associated steatotic liver injury. Rspondin-3 expression decreases with HSC activation and is associated with disease progression in patients with alcohol-associated and metabolic dysfunction-associated steatotic liver disease. These hitherto unknown protective and hepatocyte-regulating functions of HSCs via Rspondin-3, resembling the R-spondin-expressing stromal niche of other organs, should be integrated into therapeutic concepts for liver fibrosis.

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.

Project description:The molecular determinants of a healthy human liver cell phenotype remain largely uncharacterized. In addition, the gene expression changes associated with activation of primary human hepatic stellate cells, a key event during fibrogenesis, remain poorly characterized. Here, we provide the transriptomic profile underpinning the healthy phenotype of human hepatocytes, liver sinusoidal endothelial cells (LSECs) and quiescent hepatic stellate cells (qHSCs) as well as activated HSCs (aHSCs) We assess the transcriptome for purified, non-cultured human hepatocytes, liver sinusoidal cells (LSECs) and quiescent hepatic stellate cells (qHSCs) as well as culture-activated HSCs (aHSCs). Hepatocytes (n=2 donors), LSECs (n=3), qHSCs (n=3) and in vitro activated HSCs (n=3; from the same donors as the qHSCs and LSECs) were used for this study.
