Project description:Deletion of the RPS6 gene in mouse liver results in the inhibition of 40S ribosome biogenesis and the failure of hepatocytes to enter S-phase following partial hepatectomy. This microarray experiment was designed to assess the effects of RPS6 deletion on the expression of genes involved in liver regeneration following partial hepatectomy. Keywords: time course, liver RNA was isolated from mouse livers at different time-points following partial hepatectomy. Conditional deletion of the RPS6 gene was perfomed by injecting polyinosinic-polycytidylic acid in mice harbouring a floxed version of the RPS6 gene and a cre recombinase under the regulation of an interferon responsive promoter (MX-CRE). The mice used a control have also a floxed version of the RPS6 gene but lack the cre recombinaste transgene.

Project description:Purpose: The goal of this study was to determine biological consequences during liver regeneration following partial hepatectomy in mice by next-generation sequencing. A particular interest was to compare mice with either a floxed b-PDGFR allele to mice that harbored a deletion of b-PDGFR in hepatic stellate cells (HSCs), by crossing b-PDGFR fl/fl mice with transgenic GFAP-Cre mice. Methods: b-PDGFR fl/fl mice or mice with a HSC-specific deletion of b-PDGFR underwent either sham operation or 70% partial hepatectomy. Following 72 hours, livers were collected and total RNA was extracted using tizol, followed by a purification using Quiagen spin columns including an on-column DNAse digestion step. Conclusion: Our study represents a detailed analysis of hepatic transcriptome, with biologic replicates, generated by RNA-seq technology of livers following sham operation or partial hepatectomy in b-PDGFR fl/fl mice or b-PDGFRfl/fl/GRAP-Cre mice. Whole liver mRNA profiles of sham operated livers or livers collected 72hours after partial hepatectomy of beta-PDGFR fl/fl and beta-PDGFR fl/fl/GFAP-Cre (creating a hepatic stellate cell-specific deletion of b-PDGFR) mice were generated by deep sequencing, in duplicate, using Illumina HiSeq2000.

Project description:We analyzed the effect of chronic alcohol intake on the genome-wide binding activity of NF-κB during the initial response phase following partial hepatectomy. We analyzed the data in the adapted state as well as in response to partial hepatectomy, using chromatin immunoprecipitation followed by promoter microarray analysis. We found several ethanol-specific NF-κB binding target promoters in the chronic adapted state.. Partial hepatectomy induced a diet-independent shift in NF-κB binding loci relative to the transcription start sites. We employed a novel pattern count analysis to exhaustively enumerate and compare the number of promoters corresponding to the temporal binding patterns between ethanol and isocaloric pair-fed control groups. We found that NF-κB bound genes govern negative regulation of cell growth and inflammatory response immediately following hepatectomy. We, integrated the ChIP-chip results with a time series gene expression data set to identify the NF-κB promoter binding targets that showed differential gene expression changes at the baseline-adapted condition as well as after PHx. We identified a set of differential patterns of NF-κB binding that were specific to the ethanol and pair-fed control groups. We found the regulatory pathways and co-incident transcription factor binding motifs corresponding some of the key comparative-binding patterns.

Project description:Disruption of the liver’s innate ability to regenerate represents an “undruggable” clinical challenge associated with poor patient outcomes. Yes-associated protein (YAP), a transcriptional co-activator which is repressed by the Hippo pathway, is instrumental in liver regeneration. We have previously described an alternative, Hippo-independent activation of YAP mediated by tyrosine-protein phosphatase non-receptor type 11 (SHP2) inhibition. Herein, we examined the effects of YAP activation with a selective SHP1/SHP2 inhibitor, NSC-87877, on liver regeneration in murine partial hepatectomy models. In our studies, NSC-87877 led to accelerated hepatocyte proliferation, improved liver regeneration, and decreased markers of injury following partial hepatectomy. Evaluation of these effects in mice with hepatocyte-specific Yap/Taz deletion demonstrated dependence on these molecules for the enhanced regenerative response. Furthermore, administration of NSC-87877 to murine models of non-alcoholic steatohepatitis was associated with improved survival and decreased markers of injury post-hepatectomy. Evaluation of transcriptomic changes in the context of NSC-87877 administration revealed reduction in fibrotic signaling and augmentation of cell cycle signaling. Cytoprotective changes included downregulation of Nr4a1, an apoptosis inducer. Collectively, the data suggest that SHP2 inhibition induce a YAP-dependent pro-proliferative and cytoprotective enhancement of liver regeneration.
