Project description:Long noncoding RNAs (lncRNAs) play important roles in various biological processes; however, few have been identified that regulate hepatic stellate cells (HSCs) activation and the progression of liver fibrosis. To identify the possible roles of lncRNAs in regulating liver fiboris and the potential of lncRNAs as molecular markers for liver fiboris, we systematically analyzed the regulation of lncRNAs and mRNAs in a mouse model of carbon tetrachloride (CCl4)-induced liver fibrogenesis by microarray analysis, which revealed a panel of lncRNAs and mRNAs that were specifically regulated in livers of mice undergoing hepatic fibrosis. To identify the possible roles of lncRNAs in regulating liver fiboris and the potential of lncRNAs as molecular markers for liver fiboris,we determined the lncRNA and mRNA expression profiles in the livers of fibrotic mice and normal mice by lncRNA and mRNA microarrays.

Project description:Long noncoding RNAs (lncRNAs) play important roles in various biological processes; however, few have been identified that regulate hepatic stellate cells (HSCs) activation and the progression of liver fibrosis. Through a detailed analysis of the expression of lncRNAs in various tissues, we discovered the existence of a liver enriched lncRNA-LFAR1 (lncRNA-Liver Fibrosis Associated RNA1). To identify the roles of lncRNA-LFAR1 in liver fiboris, we systematically analyzed the regulation of mRNAs in the livers of mice treated with oil in combination with injection of Lenti-NC (NC, n=3), CCl4 in combination with injection of Lenti-NC (NC+CCl4, n=3), oil in combination with injection of Lenti-shLFAR1 (shLFAR1, n=3) and CCl4 in combination with injection of Lenti-shLFAR1 (shLFAR1+CCl4, n=3) by mRNA microarrays, which revealed a panel of mRNAs that were specifically regulated by lncRNA-LFAR1 in livers of mice undergoing hepatic fibrosis. To identify the roles of lncRNAs-LFAR1 in regulating liver fiboris and the potential targets of lncRNA-LFAR1 in liver fiboris,we determined the mRNA expression profiles in the livers of Balb/c mice treated with oil in combination with injection of Lenti-NC (NC, n=3), CCl4 in combination with injection of Lenti-NC (NC+CCl4, n=3), oil in combination with injection of Lenti-shLFAR1 (shLFAR1, n=3) and CCl4 in combination with injection of Lenti-shLFAR1 (shLFAR1+CCl4, n=3) by mRNA microarrays.

To identify the roles of lncRNA-LFAR1 in liver fiboris, we systematically analyzed the regulation of mRNAs in primary HSCs infected with two separated lnc-LFAR1-shRNAs by RNA-seq, which revealed a panel of mRNAs that were specifically regulated by lncRNA-LFAR1 in mouse primary HSCs.

Project description:Hepatic injury provoked by cold storage is a major problem affecting liver transplantation, as exposure to cold induces apoptosis in hepatic tissues. Long noncoding RNAs (lncRNAs) are increasingly understood to regulate apoptosis, but the contribution of lncRNAs to cold-induced liver injury remains unknown. Using RNA-seq, we determined the differential lncRNA expression profile in mouse livers after cold storage and found that expression of the lncRNA TUG1 was significantly down-regulated. Over-expression of TUG1 attenuated cold-induced apoptosis in mouse hepatocytes and liver sinusoidal endothelial cells LSECs, in part by blocking mitochondrial apoptosis and ER stress pathways. Moreover, TUG1 attenuated apoptosis, inflammation and oxidative stress in vivo in livers subjected to cold storage. Over-expression of TUG1 also improved hepatocyte function and prolonged hepatic graft survival rates in mice. These results suggest that the lncRNA TUG1 exerts a protective effect against cold-induced liver damage by inhibiting apoptosis in mice, and suggests a potential role for TUG1 as a target for the prevention of cold-induced liver damage in liver transplantation.

Project description:Hepatic fibrosis is a wound-healing response to chronic liver injury, which may result in cirrhosis and liver failure. The c-Jun N-terminal kinase-1 (JNK1) gene has been shown to be involved in liver fibrosis. Here, we aimed to investigate the molecular mechanism and identify the cell-type involved in mediating the JNK1-dependent effect on liver fibrogenesis Wild-type (WT), JNK1−/− and JNK1Δhepa (hepatocyte-specific deletion of JNK1) mice were subjected to bile duct ligation (BDL). Additionally, we performed bone marrow transplantations (BMT), isolated primary hepatic stellate cells (HSCs) and studied their activation in vitro. Serum markers of liver damage (liver transaminases, alkaline phosphatase and bilirubin) and liver histology revealed reduced injury in JNK1−/− compared to WT and JNK1Δhepa mice. Hepatocyte cell death and proliferation was reduced in JNK1−/− compared to WT and JNK1Δhepa. Parameters of liver fibrosis such as Sirius Red staining as well as Collagen IA1 and αSMA expression were down-regulated in JNK1−/− compared to WT and JNK1Δhepa livers, 4 weeks after BDL. To delineate the essential cell-type, we performed BMT of WT and JNK1-/- into JNK1-/- and WT mice, respectively. BMT experiments excluded bone marrow derived cells from having a major impact on the JNK1-dependent effect on fibrogenesis. Hence, we investigated primary HSCs from JNK1−/− livers showing reduced transdifferentiation compared with WT and JNK1Δhepa-derived HSCs. We conclude that JNK1 in HSCs plays a crucial role in hepatic fibrogenesis and thus represents a promising target for cell-directed treatment options for liver fibrosis. Control (JNK1f/f), JNK1 null (JNK1-/-) and hepatocyte-specific JNK1 null (JNK1Δhepa) mice were subjected to control, acute and chronic injury, i.e. sham or bile-duct ligation for 48h or 28 days resp., whereafter gene expression profiles were determined.

Project description:Long non-coding RNAs (lncRNAs) are involved in numerous biological functions and pathological processes. In this study, we have identified a novel lncRNA ENSMUST00000147617, named Highly Expressed in Liver Fibrosis (lnc-HELF), which is remarkably up-regulated in mouse and human fibrotic livers. To identify the roles of lnc-HELF in liver fibrosis, we performed RNA-seq to analyze the effect of lnc-HELF deficient on CCl4-induced liver fibrosis. The mice were divided in three groups: mice treated with CCl4 in combination with injection of AAV8-NC (NC_CCl4, n=3), mice treated with CCl4 in combination with injection of AAV8-shRNA-lncHELF1# (sh1_CCl4, n=3) and mice treated with CCl4 in combination with injection of AAV8-shRNA-lncHELF2# (sh2_CCl4, n=3).

Project description:To investigate the differences in microRNA expression profiles between fibrotic and normal livers, we performed microRNA microarrays for total RNA extracts isolated from mouse livers treated with carbontetrachloride (CCl4) or corn-oil for 10 weeks (n=3/group). MicroRNAs were considered to have significant differences in expression level when the expression difference showed more than two-fold change between the experimental and control groups at p<0.05. We found that 12 miRNAs were differentially expressed in CCl4-induced fibrotic liver. To induce chronic liver fibrosis, seven-week-old mice received 0.6 ml/kg body weight of carbon-tetrachloride (CCl4) dissolved in corn-oil by intraperitoneal (i.p.) injection, twice a week for 10 weeks (n=3). As a control, same number of mice was injected with equal volume of corn-oil for 10 weeks.
