Project description:Liver sex-specific long noncoding RNAs (lncRNAs) were identified based on three pools of male and three pools of female ribosomal RNA-depleted total liver RNAs, as well as three pools of male and three pools of female ribosomal RNA-depleted nuclear liver RNAs from CD-1 mice. This dataset is part of a larger study, entitled "Sex-biased lncRNAs inversely correlate with sex-opposite gene co-expression networks in Diversity Outbred mouse liver", Endocrinology (2019) 160:989-1007, PMID:30840070.

Project description:Cirrhosis is a late stage of fibrosis that fatally impairs liver function. Unfortunately, genetic animal models mimicking human cirrhosis are lacking and the molecular mechanisms remain unknown. Here we report the first murine genetic model recapitulating clinical features of cirrhosis, which are induced by hepatocyte-specific elimination of microspherule protein 1 (MCRS1), a member of the non-specific lethal (NSL) and INO80 chromatin modifier complexes. Deregulation of bile acid (BA) transporter expression, revealed by proteomic analysis of MCRS1-depleted mouse livers, with pronounced downregulation of the Na+-taurocholate cotransporting polypeptide (NTCP), causes BA accumulation in liver sinusoids. Genetic ablation of the BA receptor FXR in hepatic stellate cells (HSCs) suppresses bile duct ligation (BDL)-induced fibrosis in mice. Moreover, in vitro experiments demonstrate that fibrotic marker expression is reduced in FXR-depleted HSCs cultured in conditioned medium containing high BAs from MCRS1-depleted hepatocytes. Additionally, hepatocytic MCRS1 overexpression increases their NTCP levels, and consequently protects mice against BDL-induced liver fibrosis. Deletion of a putative SANT domain in MCRS1, also revealed by protein sequence analysis and essential for histone H3 (H3) binding, disrupts H3/HDAC1 complex formation. This evicts MCRS1 and HDAC1 from their H3 anchoring sites and increases histone lysine acetylation of BA transporter genes, independently of the NSL or INO80 complexes. Taken together, our data reveal a previously unrecognized function of MCRS1 as a novel histone acetylation regulator that binds to H3, and recruits a novel chromatin-modifying complex that maintains gene expression homeostasis and liver health. Accordingly, loss of nuclear MCRS1 correlates with increased histone acetylation in human cirrhosis samples. Regulation of histone acetylation might thus be central to cirrhotic development.

Project description:Intestinal organoids accurately recapitulate epithelial homeostasis in vivo, thereby representing a powerful in vitro system to investigate lineage specification and cellular differentiation. Here, we applied a multi-omics framework on stem cell enriched and -depleted mouse intestinal organoids to obtain a holistic view of the molecular mechanisms that drive differential gene expression during adult intestinal stem cell differentiation. Our data revealed a global rewiring of the transcriptome and proteome between intestinal stem cells and enterocytes, with the majority of dynamic protein expression being transcription-driven. Integrating absolute mRNA and protein copy numbers revealed post-transcriptional regulation of gene expression. Probing the epigenetic landscape identified a large number of cell-type specific regulatory elements, which revealed Hnf4g as a major driver of enterocyte differentiation. In summary, by applying an integrative systems biology approach we uncovered multiple layers of gene expression regulation, which contribute to lineage specification and plasticity of the mouse small intestinal epithelium.

Project description:Liver-specific depletion of HDAC3 leads to liver steatosis (fatty liver), suggesting disregulation of lipid metabolism. This is correlated with changes in lipid metabolic gene expression. Livers depleted of HDAC3 were removed from 12 week old male HDAC3 fl/fl mice (loxP sites flanking exon 4 to 7 of the HDAC3 gene encoding the catalytic domain of HDAC3) one week after the injection of AAV2/8-Tbg-Cre virus. Livers from the HDAC3 fl/fl mice injected with AAV2/8-Tbg-GFP were used as normal controls. mRNA was extracted from 100mg mouse liver samples and hybridized to Affymetrix microarrays. For each group (HDAC3 depleted liver and normal liver), we have 5 samples from different mice.
