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.

Project description:To explore how Mier1 affiects high-fat diet-fed, aging and adipose tissue Lipe knockout mice liver regeneration, we specifically knocked out liver Mier1 in high-fat diet-fed, aging and adipose tissue Lipe knockout mice through adeno-associated virus (AAV). 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. To assess the role of MIER1 in liver regeneration, we performed 70% partial hepatectomy on high-fat diet-fed, aging and adipose tissue Lipe knockout mice. We then performed RNA sequencing analysis on liver tissues collected from control and Mier1 ko groups at 0 h, 48h or 36 h after partial hepatectomy. RNA-seq analysis showed that after partial hepatectomy, MIER1 loss caused significant upregulation of genes enriched in cell proliferation relevant pathways.

AAV vectors with no sgRNA inserted (AAV-Cre) were used in control animals. To assess the role of MIER1 in liver regeneration, we performed 70% partial hepatectomy, 3 weeks after AAV injection. We then performed RNA sequencing analysis on liver tissues collected from control and Mier1 ko groups at 0 h, 24 h, 36 h, 48 h and 72 h after partial hepatectomy. Interestingly, although MIER1 depletion did not cause a significant difference in expression of cell cycle genes before surgery, the increase of cell cycle gene expression during liver regeneration was significantly enhanced after MIER1 loss. Further analysis showed that after partial hepatectomy, MIER1 loss caused significant upregulation of genes enriched in cell proliferation relevant pathways.

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. (Identification of transcriptional networks during liver regeneration (2004) Journal of Biological Chemistry)

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.

Project description:In this study, we analyzed the effects of chronic alcohol consumption on liver repair and regeneration after partial hepatectomy (PHx). Rats were fed a liquid diet containing 36% of total calories derived from ethanol for 5 weeks; corresponding pair-fed calorie-matched controls were fed diets in which ethanol calories were replaced either by carbohydrate or by fat. After 5 weeks, rats were subjected to 70% PHx and liver samples were collected at 1, 6 and 24h after the surgery. The excised liver samples at t=0 served as within-animal controls. We used Affymetrix Rat Gene 1.0 ST arrays to obtain global gene expression data from each liver sample (n=4 replicate rats, 72 arrays total). Gene expression was profiled in the chronic ethanol-fed (EtOH) and carbohydrate control pair-fed (CHO) liver prior to (control) and 1 h, 6 h, 12 h, and 24 h after partial hepatectomy (PHx).
