Project description:The goal of this experiment was to investigate the early mechanisms of human fulminant hepatitis through ConA-induced hepatitis model.Early diagnosis and interventions are important for patients with fulminant hepatitis and gene expression may be pivotal in the early diagnosis. Keyword :ConA-induced hepatitis model ConA was injected through the mouse caudal vein at one of 4 time points (0 hr, 1 hr, 3 hr, 6 hr). The effects of ConA treatment on hepatic gene expression at these time points were analyzed .There are 3 replicates at each timepoint then 4*3=12 samples in all.

Project description:In order to further discover the resistance mechanism of Rack1F/F;Alb-cre mice to LPS/ GalN-induced fulfulant hepatitis, we used genome-wide microarray expression profiling as a discovery platform to identify potential genes associated with resistance to LPS/ GalN-induced in Rack1F/F;Alb-cre mice. Fulminant hepatitis was induced by LPS/GalN in Rack1F/F;Alb-cre mice and Rack1F/F mice for 0, 1,3 and 6 hours, respectively.

Project description:The etiology of autoimmune hepatitis is poorly understood but likely involves Th1 cells producing IFN-γ. BALB/c background TGF-β1-/- mice rapidly develop fulminant Th1-mediated autoimmune hepatitis. Our aims are to profile liver gene expression in TGF-β1-/- mice, to identify gene expression pathways dependent on IFN-γ as possible targets for rational therapy, and to test potential targets directly in vivo in mice. Keywords: Comparative analysis of gene expression in livers of WT, TGFB1 & IFN knockout mice

Keywords: Comparative analysis of gene expression in livers of WT, TGFB1 & IFN knockout mice DNA microarray analyses were applied to liver RNA from TGF-β1-/- mice, TGF-β1-/- /IFN-γ-/- mice, and TGF-β1+/+ littermate controls. 3 mice from each group were analyzed in this study.

Project description:Hepatitis B virus (HBV) is an enveloped, coated, non-cytopathic and hepatotropic partially double-stranded DNA virus in the family Hepadnaviridae genus Orthohepadnavirus. Despite significant progress in the availability of safe vaccines and antiviral therapies against HBV, it still affects approximately 257 million people worldwide and is responsible for about 887,000 deaths per year around the world [4]. HBV infection, which are associated with acute and chronic liver failure responses to viruses attacked the liver, can result in inactive carrier state, chronic hepatitis, or fulminant hepatitis and put them at high risk to develop advanced liver fibrosis and cirrhosis, and even hepatocellular cancer. Many viral factors, which could affect the disparity of clinical outcomes or disease prognosis during chronic HBV infection, have been reported in previous studies; among them, the viral genotype, as well as HBV mutations ascribing the virus to a certain phenotype, was reported to be the most important factor influencing viral pathogenesis, including the change of host immune recognition, the enhanced virulence with increased HBV replication and the facilitation of cell attachment or penetration.

Project description:Death receptor-mediated hepatocyte apoptosis is implicated in a wide range of liver diseases including viral hepatitis, alcoholic hepatitis, ischemia/reperfusion injury, fulminant hepatic failure, cholestatic liver injury and cancer. Deletion of NF-ĸB essential modulator in hepatocytes (NemoΔhepa) causes the spontaneous development of hepatocellular carcinoma preceded by steatohepatitis in mice and thus serves as an excellent model for the progression from chronic hepatitis to liver cancer. In the present study we aimed to dissect the death-receptor mediated pathways that contribute to liver injury in NemoΔhepa mice. Therefore, we generated NemoΔhepa/TRAIL-/- and NemoΔhepa/TNFR1-/- animals and analyzed the progression of liver injury. NemoΔhepa/TRAIL-/- displayed a similar phenotype to NemoΔhepa mice characteristic of high apoptosis, infiltration of immune cells, hepatocyte proliferation and steatohepatitis. These pathophysiological features were significantly ameliorated in NemoΔhepa/TNFR1-/- livers. Hepatocyte apoptosis was increased in NemoΔhepa and NemoΔhepa/TRAIL-/- mice while NemoΔhepa/TNFR1-/- animals showed reduced cell death concomitant with a strong reduction in pJNK levels. Cell cycle parameters were significantly less activated in NemoΔhepa/TNFR1-/- livers. Additionally, markers of liver fibrosis and indicators of tumour progression were significantly decreased in these animals. The present data demonstrate that the death receptor TNFR1 but not TRAIL is important in determining progression of liver injury in hepatocyte-specific Nemo knockout mice.

Project description:Hepatitis C Virus (HCV) has a extremely narrow host cell tropism and robustly infects only very few cell lines, most importantly the human hepatoma cell line Huh7. This cell line was isolated from a 57-year old Japanese male with fulminant hepatitis. Different subclones and passages of the Huh7 cell line show up to 1000-fold differences in HCV replication efficiency (permissiveness). In this experiment, we sought to identify factors responsible for these differences by correlating gene expression from eight different uninfected Huh7 variants with their respective HCV permissiveness. HCV replication efficiency was determined using electroporation of a subgenomic luciferase reporter replicon (genotype 1b, "con1/ET") and measuring luciferase activity at 48h post transfection normalized to the input value at 4h p.t.. "Relative permissiveness" of cell lines corresponds to their replication efficiency, normalized to the efficiency in the lowest permissive cells (Huh7 p13 and p28).
