Epigenetic analysis of hepatocyte-like cells from MSC-Ucs.

ABSTRACT: Global DNA methylation profiling of hepatocyte-like cells. We established a protein-based artificial transcription system and successfully engineered human hepatocyte-like cells from human umbilical cord-derived mesenchymal stem cells (MSC-UCs). We utilized four artificial transcription factors (ATFs) that targeted hepatocyte nuclear factor (HNF)1α, HNF3γ, HNF4α and GATA4 (4F), and found that treatment with 4F for 3 (4Fd3) or 5 (4Fd5) days converted MSC-UCs to hepatocyte-like cells. We then examined global DNA methylation profiles of 4Fd3, 4Fd5, NTP-EGFP protein treated cells (NE) and non-treated cells (NC).

Gene expression profiling of hepatocyte-like cells from human mesenchymal stem cells

Project description:We established a protein-based artificial transcription system and successfully engineered human hepatocyte-like cells from human umbilical cord-derived mesenchymal stem cells (MSC-UCs). We utilized four artificial transcription factors (ATFs) that targeted hepatocyte nuclear factor (HNF)1α, HNF3γ, HNF4α and GATA4 (4F), and found that treatment with 4F for 5 days converted MSC-UCs to hepatocyte-like cells (4F-Heps). We then examined gene expression profiles of 4F-Heps and compared them with those of non-treated MSC-UCs (NC) or MSC-UCs treated with NTP-EGFP protein as control protein (NE).

HNF4α transduction and 5'azacytidine treatment of naïve rat liver epithelial cells (rLEC)

Project description:Neonatal liver-derived rat epithelial cells (rLEC) from biliary origin are liver progenitor cells that acquire a hepatocyte-like phenotype upon sequential exposure to hepatogenic growth factors and cytokines. Undifferentiated rLEC express several liver-enriched transcription factors including the hepatocyte nuclear factors (HNF) 3β and HNF6, but not the hepatic master regulator HNF4α. In this study, we investigated the impact of the ectopic expression of HNF4α in rLEC on both mRNA and microRNA level by means of microarray technology. In addition, we investigated the influence of subsequent DNA methyl transferase (DNMT) inhibition on the phenotype of undifferentiated rLEC by exposure to 5' azacytidine (AZA).

In vivo reprogramming drives dedifferentiation and enhances liver regeneration

Project description:Mammalian tissues have a limited regenerative capacity. Previous studies showed that dedifferentiation contributes to tissue regeneration in non-mammalian vertebrate species such as zebrafish and newt. However, dedifferentiation is rarely observed in mammalian tissues even in the neonatal stage and therefore artificial induction of dedifferentiation might enhance regeneration in mammalian tissues. Here we demonstrate that short-term expression of Yamanaka 4 factors (4F) induces dedifferentiation and proliferation in the liver by using lineage-traceable, hepatocyte-specific 4F inducible mouse model. Global transcriptome analysis shows that 4F expression transiently reduces the expression of hepatic-lineage markers and induces the expression of a large set of proliferative markers and epigenetic modifiers along with global epigenetic changes as assessed by DNA-accessibility analysis. More importantly, lineage-tracing experiments showed that 4F-expressing hepatocytes acquire liver stem/progenitor cell markers, suggesting that 4F induces partial reprogramming. Moreover, 4F enhances MyoD-mediated transdifferentiation in the liver, suggesting that 4F endows hepatocytes with plasticity. Lastly, 4F expression attenuated liver injury associated with more proliferative capacity and better survival rate, indicating that 4F enhances liver regeneration. Taken together, these results demonstrate that liver-specific 4F expression induces dedifferentiation and promotes liver regeneration.

Gene expression profiles for genetically engineered murine hepatoma Hepa8F5 cells treated with or without doxycycline, cultured as monolayer or spheroids

Project description:We developed genetically engineered Hepa/8F5 cells (available from RIKEN BioResource Center [RCB4661]), in which genes of eight liver-enriched transcription factors (LETFs)—hepatocyte nuclear factor (HNF)-1α, HNF-1β, HNF-3β [FOXA2], HNF-4α, HNF-6, CCAAT/enhancer binding protein (C/EBP)-α, C/EBP-β and C/EBP-γ—were transduced into murine hepatoma Hepa1-6 cells as drug-inducible expression cassettes [Biochem. Eng. J., 60, 67–73 (2012)]. Hepa/8F5 cells can induce high liver functions by the addition of an inducer drug (doxycycline; Dox) via overexpression of LETF genes.

Hepatocyte nuclear factor 1β gene regulation in E14.5 ureteric bud cells

Project description:HNF-1β mutations are one of the most common single-gene mutations that underlie kidney developmental disease. Hepatocyte nuclear factor 1β (HNF-1β) is essential for kidney development, but its functions in ureteric bud (UB) branching morphogenesis are incompletely understood. We isolated E14.5 UB cells using fluorescence-activated cell sorting, and performed RNA-sequencing to compare gene expression in wild-type and HNF-1β deficient UB cells. 1632 genes have significantly lower expression in the HNF-1β deficient UB cells and 2223 genes have significantly higher expression in HNF-1β deficient UB cells.

Gene expression profiles for genetically engineered human hepatoma HepG2/8F_HS cells with or without heat treatment, cultured as monolayer or spheroids

Project description:We developed genetically engineered HepG2/8F_HS cells, in which eight liver-enriched transcription factor (LETF) genes—hepatocyte nuclear factor (HNF)-1α, HNF-1β, HNF-3β, HNF-4α, HNF-6, CCAAT/enhancer binding protein (C/EBP)-α, C/EBP-β and C/EBP-γ— under the control of TRE/PCMVmin promoter were introduced into a previously developed human hepatoma cell line (HepG2-HSP). The heat-inducible synthetic promoter system was introduced into HepG2 cells and tetracycline-responsive transactivator (tTA) and enhanced green fluorescent protein (EGFP) were expressed via positive feedback of tTA transcription in response to heat treatment. HepG2/8F_HS cells can induce high liver functions by heat treatment via overexpression of LETF genes.

Developmentally regulated isoform of HNF4α reprograms the adult liver

Project description:Hepatocyte Nuclear Factor 4α (HNF4α), master regulator of hepatocyte differentiation, is regulated by two promoters (P1 and P2). P1-HNF4α but not P2-HNF4α is expressed in normal adult liver while both P1- and P2-HNF4α are expressed in fetal liver and liver cancer. To determine the physiological function of the HNF4α isoforms, we compared P2-HNF4α-expressing exon swap mice to wildtype (WT) using RNA-seq, ChIP-seq, proteomics, protein binding microarrays (PBMs) and metabolomics. P2-HNF4α orchestrates a distinct transcriptomic and metabolomic profile.

Developmentally regulated isoform of HNF4α reprograms the adult liver

Project description:Hepatocyte Nuclear Factor 4α (HNF4α), master regulator of hepatocyte differentiation, is regulated by two promoters (P1 and P2). P1-HNF4α but not P2-HNF4α is expressed in normal adult liver in fed conditions. Both P1- and P2-HNF4α are expressed in fetal liver. P2-HNF4α expression is increased in fasted conditions, high fat diet, alcoholic liver and liver cancer. To determine the target genes of the P1- and P2-HNF4α isoforms, we compared P2-HNF4α-expressing exon swap mice (a7HMZ) to wildtype (WT) male mice. Liver ChIP-seq samples were taken at 10:30 AM (ZT 3.5)

Expression profile analysis of inflammatory response regulated by hepatocyte nuclear factor 4α

Project description:To obtain a genomic view of hepatocyte nuclear factor-4α (HNF-4α) in the regulation of the inflammatory response, microarray analysis was used to probe the expression profile of an inflammatory response induced by cytokines in a model of knock-down HNF-4α HepG2 cells. The results indicate an extensive role for HNF-4α plays in the regulation of a large number of the liver-specific genes. Majority of genes (71%) affected by cytokine treatment are also affected by HNF-4α knock-down. This significant overlap suggests that HNF-4α may play a role in regulating the cytokine-induced inflammatory response.
