Project description:The effect of Tlr4P712H mutation (rendering TLR4 non-functional), or gut-sterilization by antbiotics, on the induction of tumorgenesis by CCl4 and diethylnitrosamine (DEN) was characterized. Affymetrix Mouse 430 2.0 gene expression measurements were used to characterize the transcriptomic basis of the effects of the above treatments and genotypes on tumorgenesis. Gene expression of mouse livers of A. Normal liver from WT C3H/HeOuJ mice, B. HCC from WT C3H/HeOuJ mice treated with CCl4 and DEN, C.HCC from TLR4-mutant C3H/HeJ mice (Tlr4P712H) treated with CCl4 and DEN and D.HCC from WT C3H/HeOuJ mice treated with antibiotics (a combination of ampicillin (1 g/l), neomycin [1 g/l], metronidazole[1 g/l] and vancomycin [500 mg/l] in drinking water) and CCl4 and DEN were characterized.
Project description:To investigate the altered gene expression levels in mouse fibrotic liver tissues, C57BL6/J mice were intraperitoneally injected with CCl4 or vehicle twice every week. After 8 weeks, livers were harvested and RNA was extracted by Trizol. The gene expression levels were analyzed and compared between CCl4 treated group and vehicle treated (control) group.
Project description:Analysis of gene expression levels between CCl4 induced mouse fibrotic liver tissues and vehicle treated mouse control liver tissues.
Project description:The present study examined hypermethylated and downregulated genes specific to carbon tetrachloride (CCl4) by Methyl-Seq analysis combined with expression microarray analysis in the liver of rats treated with CCl4 or N-nitrosodiethylamine (DEN) for 28 days, by excluding those with DEN.

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.
Project description:We used Adamts12−/− and wild-type mice generated and genotyped by El Hour et al. 2010 (PMID: 20208563). eight-week-old females were treated by intraperitoneal injections of CCl4 (Sigma-Aldrich, St. Louis, MO, USA) diluted at 3% v/v in olive oil. A single dose of CCl4 0.3 ml/kg of mouse body weight was administered (acute treatment) and mice were sacrificed after 4h, 12h, 24h or 7 days. Control mice were treated with the vehicle (olive oil). Liver samples were collected, weighed and treated as previously described (Kesteloot et al. 2007, PMID: 17929299). We performed gene expression profiling analysis using data obtained from liver samples of wild-type or Adamts12_KO mice at different time points after CCl4 (or vehicle) injection.
