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.

ChIP-seq analysis of E2f4, H3K4me2 and H3K27ac in the mouse livers

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. Correspondingly, these promoters showed increased H3k4me2 and H3k27ac marks, indicating de-repression of these E2f target genes. The post partial hepatectomy mice liver cells were fixed and isolated, analysis of genomic occupancy of E2f4,H3K4me2,H3K27ac in hepatocytes from Arid1a WT and Arid1a liver specific KO mice by ChIP-seq.

Regulation of Liver Regeneration by Hepatocyte O-GlcNAcylation in Mice

Project description:We studied the role of the post-translational modification called O-GlcNAcylation during liver regeneration. Here we generated O-GlcNAc transferase (OGT-KO) and O-GlcNAcase (OGA-KO) hepatocyte-specific knock-out mice. 70% partial hepatectomy (PHX) was performed to induce liver regeneration. We showed that OGA-KO mice had normal liver regeneration whereas OGT-KO mice had a defect in the termination of liver regeneration.

H3K27ac ChIP-seq Analysis in WT and MIER1 Depletion Liver Tissues at 0 h and 24 h after 70% Partial Hepatectomy

Project description:To explore how Mier1 influence the genome H3K27ac levels during liver regeneration, we performed H3K27ac chromatin immunoprecipitation followed by sequencing in control and liver-specific Mier1 ko liver tissues at 0 h and 24 h after 70% partial hepatectomy (PHx). The mice we used were knocked in a Cre-induced Cas9 expression cassette. Through tail vein injection, we delivered the AAV expressing Cre-recombinase under TBG promoter, and sgRNA targeting Mier1 (AAV-Mier1 sgRNA), into the adult Cas9 knockin mice to knock out the Mier1 gene in liver. AAV vectors with no sgRNA inserted (AAV-Cre) were used in control animals.Then we performed 70% partial hepatectomy, 3 weeks after AAV injection. Consistent with the increased expression of cell cycle genes during liver regeneration, we observed increased signals of H3K27ac at 24 h after hepatectomy, especially near some cell cycle genes, after MIER1 depletion in liver tissue.

Transcription profiling of wild type and C/EBPbeta deficient mice during a partial hepatectomy time series to identify transcriptional targets of C/EBPbeta

Project description:The aim of this experiment was to use microarray analysis to compare the response of wild type (WT) and C/EBPbeta deficient (KO) mice during a partial hepatectomy time course in hopes of identifying transcriptional targets of C/EBPbeta. In addition, the WT time course alone was examined to analyze mammalian cellular proliferation in vivo. In the partial hepatectomy model, quiescent hepatocytes reenter the cell cycle and progress in a synchronous fashion. This allows for the elucidation of regulatory networks operative in mammalian cell cycle.

ChIP-seq analysis of Arid1a and C/ebpÎ± in the mouse livers

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 and other adult tissues results in improved organ regeneration. Within SWI/SNF complexes, Arid1a physically interacts with C/ebpÎ±, a hepatocyte transcription factor that drives maturation and limits proliferation. Genome-wide analysis showed that loss of Arid1a reduces the recruitment and activity of C/ebpÎ± on target promoters, resulting in expression programs that favor regeneration and cellular fitness during injury. Arid1a binding is enriched in promoters near transcriptional start sites (TSSs), and C/ebpÎ± binds at precisely the same positions, indicating that Arid1a facilitates C/ebpÎ± binding across the genome. Perfuse and isolate primary hepatocytes from mice livers, analysis of genomic occupancy of C/ebpÎ± and H3K4me2 in hepatocytes from Arid1a WT and Arid1a liver specific KO mice by ChIP-seq. Analysis of genomic occupancy of Arid1a in the hepatocytes from V5-Arid1a transgenic mouse by ChIP-seq.
