Liver-specific matrin-3 knockout alters the chromatin accessibility in the liver of mice [ATAC-seq]

ABSTRACT: Matrin-3 is an RNA-binding protein involved in the pathogenesis of human diseases. Here we examined its previously uncharacterized role in regulating chromatin accessibility in the liver of mice. Bulk ATAC-seq and bioinformatics analysis identified 523 and 829 differential peaks (FDR < 0.05), respectively, in the liver of female mice fed a chow diet or 60% HFD for 16 weeks. Peak annotation by HOMER and ChIPseeker identified 183 and 444 genes, respectively, that are associated with the differential peaks. Enrichr analysis of these genes revealed that Hallmark terms such as "Xenobiotic metabolism" was enriched in the liver of chow-fed and HFD-fed mice. TRRUST database analysis from Metascape uncovered that Hnf4α is the main transcription factor regulating these peak-associated genes in the liver of chow-fed mice, and Hnf4α and Nr1i3 are the main transcription factors regulating these peak-associated genes in the liver of HFD-fed mice. Our data demonstrated that liver-specific matrin-3 deficiency alters chromatin accessibility likely affecting the action of two transcription factors Hnf4α and Nr1i3 in the liver of mice.

Liver-specific matrin-3 knockout alters the hepatic transcriptome of chow diet-fed mice [RNA-seq]

Project description:Matrin-3 is an RNA-binding protein involved in the pathogenesis of human diseases. Here we examined the hepatic transcriptome of chow-diet fed mice. Bulk RNA-seq and bioinformatics analysis identified 646 and 145 differentially expressed genes (Padj < 0.05), respectively in the livers of female and male matrin-3 LKO mice. Enrichr analysis of these DEGs revealed several common Hallmark terms including cholesterol homeostasis, fatty acid metabolism, xenobiotic metabolism, and epithelial mesenchymal transition between female and male mice. Our data demonstrated that liver-specific matrin-3 deficiency re-programs the hepatic transcriptome in the liver of chow diet-fed mice.

Liver-specific matrin-3 knockout alters the hepatic transcriptome of high-fat diet-fed mice [RNA-seq]

Project description:Matrin-3 is an RNA-binding protein involved in the pathogenesis of human diseases. Here we examined its previously uncharacterized role in limiting hepatic steatosis and stress response via the constitutive androstane receptor. Matrin-3 expression was induced in the steatotic livers of mice and humans. Liver-specific matrin-3 knockout (LKO) exacerbated high-fat diet (HFD)-induced steatosis, acute phase response, and inflammation in the liver of mice. Bulk RNA-seq and bioinformatics analysis identified 1,333 and 239 differentially expressed genes (fold change > 1.5 & Padj < 0.05), respectively in the livers of female and male matrin-3 LKO mice. Gene Set Enrichment Analysis revealed that the top most enriched Gene Ontology Biological Process was the “Xenobiotic metabolic process” in female matrin-3 floxed mice that is downregulated. The top two enriched biological processes are “Acute inflammatory response” and “Acute phase response” in the liver of female LKO mice that are upregulated. Several GO terms related to lipid metabolism and xenobiotic metabolism were enriched in the livers of male mice. Real-time qPCR revealed that the expression of many genes involved in xenobiotic metabolism was reduced in the liver of female LKO mice and to a lesser extent in the liver of male LKO mice, while the expression of acute-phase response genes was induced in the liver of female but not male LKO mice. Our data demonstrated that liver-specific matrin-3 deficiency re-programs the hepatic transcriptome enriched for xenobiotic metabolism pathway, acute-phase and inflammatory response signaling in the liver of HFD-fed mice.

Systems analysis of hepatic insulin resistance identifies RGS4 as a key mediator of metabolic adaptation

Project description:We profiled the transcriptomes of chow diet-fed and high-fat diet-fed mice across insulin stimulation time points. We also profiled the effects of metformin treatment on mouse liver transcritomes. Our temporal analyses of chow-diet and 16 week high-fat diet transcriptomics following insulin stimulation uncovered several regulator of G-protein signaling genes, particularly Rgs4, that are specifically regulated transcriptionally in HFD livers following insulin stimulation. We validated these findings with additional assays of RGS4 mRNA and protein levels and characterized this molecule's role in regulating hepatic insulin responses in mice.

Gene expression in the liver, effect of maternal high-fat diet during or prior to pregnancy

Project description:The present study aimed to examine the effect of high-fat diet prior to pregnancy on the liver of mouse offspring. Female C57BL/6J mice were fed a normal chow (15.2% fat by energy) (CTR and CTR-PP groups) or a high-fat chow (31.2% fat by energy) (HFD and HFD-PP groups) for 3−4 weeks and then mated with male C57BL/6J mice fed normal chow. Some mothers continued on the same diet until pups reached 21 days of age (CTR and HFD), and others were fed the different chows from gestational day 0 (CTR-PP and HFD-PP) to determine the effects of a high-fat diet during the pre-pregnancy period in HFD-PP/CTR and HFD/CTR-PP comparisons. RNA sample was taken from liver of 3-week-old mouse prenatally received high-fat diet prior to pregnancy, during pregnancy and lactation, or through prior to and during pregnancy and lactation, while control RNA was taken from control counterpart prenatally received normal diet alone. Comparisons among groups were made by one-color method with normalized data from Cy3 channels for data analysis.

Proteomics reveals PFOS-induced alteration of lipid utilization and xenobiotic metabolism in a model of PFOS-augmented diet-induced fatty liver

Project description:Perfluorooctanesulfonic acid (PFOS) is a persistent, bio-accumulative pollutant that has been used for the last 60+ years in numerous industrial and commercial applications. In mice, PFOS administration is known to induce hepatomegaly and hepatic steatosis. The aim of the present study was to evaluate potential PFOS and diet interactions and explore the mechanism of PFOS induced liver lipid accumulation. Prior to PFOS administration, mice were fed either a standard chow diet (SD) or 60% kCal high fat diet (HFD) for 4 weeks to establish significant body weight increase. After 4 weeks of diet acclimation, the treatment groups received 0.0003% PFOS in diet for an additional 10 weeks. In addition, a subset of the mice fed HFD were switched to a SD (H-SD) to mimic weight-loss induced improvement of hepatic steatosis. A total of six treatment groups: i) SD, ii) HSD, iii) HFD (H), iv) SD +PFOS(SDP), v) H-SD +PFOS (HSDP), and vi) HFD +PFOS (HP) were included. PFOS and lipid concentrations were measured in both serum and liver. Relative liver mRNA expression was determined by targeted bead array and proteins were quantified using untargeted mass spectrometry. PFOS exposure increased liver weight, and in the HFD increased liver triglycerides and liver cholesterol content. Gene and protein expression in the liver demonstrated that PFOS exposure induced lipid utilization and xenobiotic metabolism pathways, and in a HFD, induced lipid synthesis. The data suggests that PFOS exposure acts on lipid utilization genes and exacerbates hepatic steatosis in mice fed a HFD.
