LncRNAs expression profiles in the livers of C57Bl/6 mice after partial hepatectomy

ABSTRACT: Liver regeneration has important implications because many therapeutic strategies for the surgical treatment of liver diseases, such as removal of liver tumors and liver transplantation, depend on the ability of the liver to regenerate physically and functionally. Recent studies reported that lncRNAs control cell proliferation in hepatocellular carcinoma (HCC). However, the role of lncRNAs in liver regeneration and the overall mechanisms remain largely unknown. To address this issue, we carried out a genome-wide lncRNA microarray analysis during liver regeneration in mice after 2/3 partial hepatectomy (PH) at various time points. The results revealed differential expression of thousands of lncRNAs during liver regeneration.

LncRNAs expression profiles in the livers of C57Bl/6 mice after partial hepatectomy

Project description:Liver regeneration has important implications because many therapeutic strategies for the surgical treatment of liver diseases, such as removal of liver tumors and liver transplantation, depend on the ability of the liver to regenerate physically and functionally. Recent studies reported that lncRNAs control cell proliferation in hepatocellular carcinoma (HCC). However, the role of lncRNAs in liver regeneration and the overall mechanisms remain largely unknown. To address this issue, we carried out a genome-wide lncRNA microarray analysis during liver regeneration in mice after 2/3 partial hepatectomy (PH) at various time points. The results revealed differential expression of thousands of lncRNAs during liver regeneration. Six-week-old male wildtype C57Bl/6 mouse liver samples were obtained at 0, 1.5, 12, and 24 hours after 2/3 PH, and three mice were analyzed for each time point. Total RNA was isolated using Trizol.Mouse Stringent LncRNA Array (4 x 44K, ArrayStar, Rockville, MD) were used to monitor the expression level of approximately 14000 lncRNAs identified from the NCBI RefSeq, UCSC, RNAdb2.0, NRED, Fantom3.0 and UCRs. LncRNAs differentially expressed were identified by comparing expression levels during liver regeneration in mice after 2/3 partial hepatectomy (PH) at various time points.

Expression data from human livers shortly following partial hepatectomy (PHx)

Project description:The liver has a remarkable ability to regenerate, with the best experimental model for regeneration being partial hepatectomy (PHx), in which up to two-thirds of the liver may be removed, and the residual lobes enlarge to make up for the missing mass in a few days’ time. Liver regeneration has been extensively studied, mainly in rodent models, and characterized in terms of transcriptional regulation of gene expression. However, little is known regarding regulation of gene expression in a human model of regeneration following PHx. We used microarrays to follow gene expression changes shortly following PHx.

Characterization of hepatic gene expression during liver regeneration in response to partial hepatectomy

Project description:This SuperSeries is composed of the following subset Series: GSE20425: Hepatic gene expression during liver regeneration in response to partial hepatectomy: early time points (0.5h,1h,2h,4h) GSE20426: Hepatic gene expression during liver regeneration in response to partial hepatectomy: late time points (24h, 38h, 48h) Refer to individual Series

Expression data from rat hepatocyte during liver regeneration after partial hepatectomy

Project description:The recovery of liver mass is mainly mediated by proliferation and enlargement of hepatocytes after partial hepatectomy. Studying the gene expression profiles of hepatocytes after partial hepatectomy will be helpful in exploring the mechanism of liver regeneration. We used microarrays to further highlight the regulatory role of hepatocyte in liver regeneration at gene transcription level. Rat liver regeneration after partial hepatectomy (PH) is a good model to study the regulation of cell proliferation. We isolated hepatocytes from regenerating liver at 9 time points (2, 6, 12,24, 30, 36, 72, 120, and 168h) after PH and measured gene expression profiles of hepatocytes from 2h to 168h with rat Genome 230 2.0 gene chip. Each sample corresponding to one time point was hybridized onto one array. The experiment was repeated 3 times for each time point. In total, 10 time points were measured and 0h was used control group. After careful quality control analyses of each chip, Affymetrix GCOS 2.0 software was used to analyze the data. The relevance of gene expression profiles and biological processes was analyzed by bioinformatics and systems biology.

Effect of conditional deletion of S6 ribosomal protein following partial hepatectomy

RNA-seq transcriptonal profiling in partial hepatectomy liver tissues in Arid1a WT and liver specific KO mice.

Project description:Arid1a is the subunit of SWI/SNF complex, which was reported to guide SWI/SNF to DNA. Here, we found that loss of Arid1a in the liver results in improved liver regeneration after partial hepatectomy.Genome-wide analysis showed that after hepatectomy,loss of Arid1a reduces the recruitment and activity of E2F4 on target promoters, resulting in expression programs that favor regeneration during injury.RNAseq shows transcriptional profiling in WT and Arid1a LKO livers pre- and post-hepatectomy, which confirmed the E2F4 target genes and cell cycle genes were upregulated after hepatectomy. After partial hepatectomy, liver transcriptional profiling in WT and Arid1a liver specific KO mice were generated by RNA-seq analysis.

Effect of conditional deletion of S6 ribosomal protein following partial hepatectomy

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.

Expression data from rat liver tissue during liver regeneration after partial hepatectomy.

Project description:The liver has extraordinary powers of regeneration after partial hepatectomy (PH). Changes of gene expression play a key role in cell proliferation and differentiation during liver regeneration (LR). To understand the molecular mechanisms underlying LR, this study was designed to assess the changes of rat hepatic gene expression in a timely manner. We used microarrays to further highlight the regulatory role of rat liver tissue in liver regeneration at gene transcription level.
