Project description:To identify the MeCP2 targets gene during the very early stage of liver regeneration，ChIP-seq analyses in control and Mecp2-cKO mice livers before and 6 h after PHx were performed. We found 3048 Mecp2-dependent genes that were differentially expressed in a Mecp2-dependent manner.

Project description:miRNA expression was profiled before and during liver regeneration following 2/3 partial hepatectomy (PHx) in chronic ethanol-fed (EtOH) and pair-fed carbohydrate control (CHO) rats. Prior to PHx, EtOH animals were fed a liquid diet containing 36% of the calories from ethanol for 5 weeks. Left lateral and medial (LLM) lobes were removed at time of PHx and used as t = 0 biological controls. Remnant liver tissue (PHx) was harvested 1 h, 6 h, 12 h, and 24 h after PHx. RNA from 4 biological replicates was pooled for profiling miRNA expression on Agilent Rat miRNA Microarrays v1.0.

Project description:Genome-wide expression analysis revealed that 3653 mRNAs and 465 putative lncRNAs were differentially expressed compared to transcripts isolated from livers of control sham operated mice. Analysis was done using the NCode Mouse Non-coding RNA Microarray (Invitrogen), which contains 25,179 coding featues and 10,802 noncoding features. To identify lncRNAs that regulate cell proliferation during liver regeneration, we analysed lncRNA expression profiles in mouse liver tissue collected at 4, 12, 36, and 72 hours after PHx, using Sham operated mouse livers as control. -------------------------- submitter cannot locate original raw data files

Project description:This study was carried out to investigate the mechanism behind the enhanced liver regenerative response observed in Uhrf1hepKO mice. Livers was collected at baseline and at 24hrs, 30hrs, 40hrs, 48hrs, 96hrs, 7days and 4 weeks following 2/3 partial hepatectomy surgery (PHx). These timepoints correspond to key cell cycle events that occur following PHx as established in literature.

Project description:The liver possesses remarkable regenerative capacity in response to injury. Upon partial hepatectomy (PHx), terminally differentiated hepatocytes in the remaining liver enter the cell cycle and restore the liver mass and function within weeks. However, liver regeneration is often impaired in livers with chronic diseases. Survivin, an inhibitor of apoptosis protein (IAP) and member of chromosome passenger complex (CPC), plays versatile roles in cell mitosis and apoptosis. We and others found that the expression of Survivin was highly increased in liver during PHx-induced liver regeneration, which indicated that Survivin played important roles in this process. However, the function of Survivin in liver regeneration remains largely undefined. Here, using mice with genetic deletion of Survivin, we found that during PHx-induced liver regeneration Survivin regulated both hepatocyte G1/S phase transition by inhibiting the expression of p21 and G2/M phase transition by regulating the localization of CPC. Moreover, restoration of Survivin expression in Survivin-deficient hepatocytes inhibited p21 expression and promote both hepatocyte G1/S and G2/M transition during PHx-induced liver regeneration.

Project description:Adult liver has enormous regenerative capacity as it can regenerate after losing two-thirds of its mass while sustaining essential metabolic functions. How the liver balances dual demands for increased proliferative activity with maintenance of organ function is unknown, but essential to prevent liver failure. Using partial hepatectomy (PHx) in mice to model liver regeneration, we integrated single-cell RNA and ATAC sequencing to map state transitions in ~ 13,000 hepatocytes at single-cell resolution as livers regenerated, and validated key findings with immunohistochemistry, to uncover how the organ regenerates hepatocytes while simultaneously fulfilling its vital tissue-specific functions. After PHx, hepatocytes rapidly and transiently diversified into multiple distinct populations with distinct functional bifurcation: some retained the chromatin landscapes and transcriptomes of hepatocytes in undamaged adult livers while others transitioned to acquire chromatin landscapes and transcriptomes of fetal hepatocytes. Injury-related signaling pathways known to be critical for regeneration were activated in transitioning hepatocytes and the most fetal-like hepatocytes exhibited chromatin landscapes that were enriched with transcription factors regulated by those pathways.
