Abstract
Butyrate contributes epigenetically to the changes in cellular function and tissue development of the rumen in ruminant animals, which might be achieved by its genetic or epigenetic regulation of gene expression. To explore the role of butyrate on bovine rumen epithelial function and development, this study characterized genome-wide H3K27ac modification changes and super-enhancer profiles in rumen epithelial primary cells (REPC) induced with butyrate by ChIP-seq, and analyzed its effects on gene expression and functional pathways by integrating RNA-seq data. The results showed that genome-wide acetylation modification was observed in the REPC with 94,675 and 48,688 peaks in the butyrate treatment and control group, respectively. A total of 9750 and 5020 genes with increased modification (H3K27ac-gain) and decreased modification (H3K27ac-loss) were detected in the treatment group. The super-enhancer associated genes in the butyrate-induction group were involved in the AMPK signaling pathway, MAPK signaling pathway, and ECM-receptor interaction. Finally, the up-regulated genes (PLCG1, CLEC3B, IGSF23, OTOP3, ADTRP) with H3K27ac gain modification by butyrate were involved in cholesterol metabolism, lysosome, cell adhesion molecules, and the PI3K-Akt signaling pathway. Butyrate treatment has the role of genome-wide H3K27ac acetylation on bovine REPC, and affects the changes in gene expression. The effect of butyrate on gene expression correlates with the acetylation of the H3K27ac level. Identifying genome-wide acetylation modifications and expressed genes of butyrate in bovine REPC cells will expand the understanding of the biological role of butyrate and its acetylation.

Abstract
A recent International Diabetes Federation report suggests that more than 463 million people between 20 and 79 years have diabetes. Of the 20 million women affected by hyperglycemia during pregnancy, 84% have gestational diabetes. In addition, more than 1.1 million children or adolescents are affected by type 1 diabetes. Factors contributing to the increase in diabetes prevalence are complex and include contributions from genetic, environmental, and epigenetic factors. However, molecular regulatory mechanisms influencing the progression of an individual towards increased susceptibility to metabolic diseases such as diabetes are not fully understood. Recent studies suggest that the pathogenesis of diabetes involves epigenetic changes, resulting in a persistently dysregulated metabolic phenotype. This review summarizes the role of epigenetic mechanisms, mainly DNA methylation and histone modifications, in the development of the pancreas, their contribution to the development of diabetes, and the potential employment of epigenetic modulators in diabetes treatment.

Abstract
Here we show that scratch family transcriptional repressor 1 (SCRT1), a zinc finger transcriptional regulator, is a novel regulator of beta cell function. SCRT1 was found to be expressed in beta cells in rodent and human islets. In human islets, expression of SCRT1 correlated with insulin secretion capacity and the expression of the insulin (INS) gene. Furthermore, SCRT1 mRNA expression was lower in beta cells from T2D patients. siRNA-mediated Scrt1 silencing in INS-1832/13 cells, mouse- and human islets resulted in impaired glucose-stimulated insulin secretion and decreased expression of the insulin gene. This is most likely due to binding of SCRT1 to E-boxes of the Ins1 gene as shown with ChIP. Scrt1 silencing also reduced the expression of several key beta cell transcription factors. Moreover, Scrt1 mRNA expression was reduced by glucose and SCRT1 protein was found to translocate between the nucleus and the cytosol in a glucose-dependent fashion in INS-1832/13 cells as well as in a rodent model of T2D. SCRT1 was also regulated by a GSK3β-dependent SCRT1-serine phosphorylation. Taken together, SCRT1 is a novel beta cell transcription factor that regulates insulin secretion and is affected in T2D.

HISTONE DEACETYLASE 9 stimulates auxin-dependent thermomorphogenesis in Arabidopsis thaliana by mediating H2A.Z depletion. Proc Natl Acad Sci U S A 2019; 116:25343-25354.

Abstract
Many plant species respond to unfavorable high ambient temperatures by adjusting their vegetative body plan to facilitate cooling. This process is known as thermomorphogenesis and is induced by the phytohormone auxin. Here, we demonstrate that the chromatin-modifying enzyme HISTONE DEACETYLASE 9 (HDA9) mediates thermomorphogenesis but does not interfere with hypocotyl elongation during shade avoidance. HDA9 is stabilized in response to high temperature and mediates histone deacetylation at the YUCCA8 locus, a rate-limiting enzyme in auxin biosynthesis, at warm temperatures. We show that HDA9 permits net eviction of the H2A.Z histone variant from nucleosomes associated with YUCCA8, allowing binding and transcriptional activation by PHYTOCHROME INTERACTING FACTOR 4, followed by auxin accumulation and thermomorphogenesis.

Prominent action of butyrate over β-hydroxybutyrate as histone deacetylase inhibitor, transcriptional modulator and anti-inflammatory molecule. Sci Rep 2019; 9:742. [PMID: 30679586 PMCID: PMC6346118 DOI: 10.1038/s41598-018-36941-9] [Citation(s) in RCA: 128] [Impact Index Per Article: 25.6] [Reference Citation Analysis] [Abstract] [Track Full Text] [Download PDF] [Figures] [Journal Information] [Subscribe] [Scholar Register] [Received: 07/25/2018] [Accepted: 11/26/2018] [Indexed: 12/16/2022] Open
Abstract
Butyrate and R-β-hydroxybutyrate are two related short chain fatty acids naturally found in mammals. Butyrate, produced by enteric butyric bacteria, is present at millimolar concentrations in the gastrointestinal tract and at lower levels in blood; R-β-hydroxybutyrate, the main ketone body, produced by the liver during fasting can reach millimolar concentrations in the circulation. Both molecules have been shown to be histone deacetylase (HDAC) inhibitors, and their administration has been associated to an improved metabolic profile and better cellular oxidative status, with butyrate inducing PGC1α and fatty acid oxidation and R-β-hydroxybutyrate upregulating oxidative stress resistance factors FOXO3A and MT2 in mouse kidney. Because of the chemical and functional similarity between the two molecules, we compared here their impact on multiple cell types, evaluating i) histone acetylation and hydroxybutyrylation levels by immunoblotting, ii) transcriptional regulation of metabolic and inflammatory genes by quantitative PCR and iii) cytokine secretion profiles using proteome profiling array analysis. We confirm that butyrate is a strong HDAC inhibitor, a characteristic we could not identify in R-β-hydroxybutyrate in vivo nor in vitro. Butyrate had an extensive impact on gene transcription in rat myotubes, upregulating PGC1α, CPT1b, mitochondrial sirtuins (SIRT3-5), and the mitochondrial anti-oxidative genes SOD2 and catalase. In endothelial cells, butyrate suppressed gene expression and LPS-induced secretion of several pro-inflammatory genes, while R-β-hydroxybutyrate acted as a slightly pro-inflammatory molecule. Our observations indicate that butyrate induces transcriptional changes to a higher extent than R-β-hydroxybutyrate in rat myotubes and endothelial cells, in keep with its HDAC inhibitory activity. Also, in contrast with previous reports, R-β-hydroxybutyrate, while inducing histone β-hydroxybutyrylation, did not display a readily detectable HDAC inhibitor activity and exerted a slight pro-inflammatory action on endothelial cells.

Chriett S, Zerzaihi O, Vidal H, Pirola L. The histone deacetylase inhibitor sodium butyrate improves insulin signalling in palmitate-induced insulin resistance in L6 rat muscle cells through epigenetically-mediated up-regulation of Irs1. Mol Cell Endocrinol 2017; 439:224-232. [PMID: 27619406 DOI: 10.1016/j.mce.2016.09.006] [Citation(s) in RCA: 23] [Impact Index Per Article: 3.3] [Reference Citation Analysis] [Abstract] [Key Words] [MESH Headings] [Track Full Text] [Journal Information] [Submit a Manuscript] [Subscribe] [Scholar Register] [Received: 04/27/2016] [Revised: 09/07/2016] [Accepted: 09/08/2016] [Indexed: 02/06/2023]
Abstract
Dietary administration of the histone deacetylase (HDAC) inhibitor butyric acid - a short chain fatty acid present in milk products and also bacterially produced in the intestine - has been shown to increase energy expenditure and favour insulin sensitivity in mice through induction of PGC1α (peroxisome proliferator-activated receptor gamma co-activator 1α) and AMPK (AMP-activated protein kinase) in skeletal muscle, and a consequential increase of mitochondrial fatty acid oxidation. Here, we investigate whether such physiological improvements are associated to epigenetic effects dependent on increased histone acetylation and whether butyrate exerts a direct action on skeletal muscle insulin signalling. We show that sodium butyrate (NaBut) ameliorates the insulin-resistant phenotype, induced in L6 myotubes by prolonged exposure to palmitate, by i) increasing the insulin-induced phosphorylation of both PKB (protein kinase B) and MAPK (mitogen activated protein kinase), the two branches of insulin signalling and ii) increasing histone H3 acetylation - even in the presence of palmitate - on chromatin in proximity of the Irs1 (insulin receptor substrate 1) transcriptional start site. Consequently, NaBut induced Irs1 mRNA and protein overexpression, which in turn relayed higher insulin-stimulated IRS1 tyrosine phosphorylation and PI 3-kinase (phosphoinositide 3-kinase) association, suggesting that the increased IRS1 expression may mediate the insulin-sensitizing effects of NaBut. Furthermore, downstream of PKB, NaBut induced GSK3β gene upregulation. Our observations indicate that NaBut - through its action as HDAC inhibitor - can promote insulin responsiveness in L6 myotubes under conditions of lipid-induced insulin resistance.

Dysregulation of sirtuins and key metabolic genes in skeletal muscle of pigs with spontaneous intrauterine growth restriction is associated with alterations of circulating IGF-1. Gen Comp Endocrinol 2016; 232:76-85. [PMID: 26769588 DOI: 10.1016/j.ygcen.2015.12.028] [Citation(s) in RCA: 8] [Impact Index Per Article: 1.0] [Reference Citation Analysis] [Abstract] [Key Words] [MESH Headings] [Track Full Text] [Journal Information] [Submit a Manuscript] [Subscribe] [Scholar Register] [Received: 08/04/2015] [Revised: 12/04/2015] [Accepted: 12/29/2015] [Indexed: 12/12/2022]
Abstract
Prenatal and early postnatal life determines future health, and intrauterine growth restriction (IUGR) - associated low birth weight predisposes to metabolic syndrome in adulthood. We hypothesize here that IUGR might induce hormonal and gene expression alterations predisposing to metabolic disease. Using a porcine model of spontaneous IUGR, we determined in utero (71, 112days post-conception) and early-postnatal (2days post-birth) IGF-1, insulin and leptin levels, and in parallel we investigated, in skeletal muscle, the developmental expression patterns of sirtuins and metabolic and signaling genes IRS1, GLUT4, HK2 and GAPDH. IUGR was associated with impaired IGF-1 plasmatic levels. Gene expression of sirtuin 1, 5, 6, 7, GLUT4 and HK2 exhibited significant correlations with gestational age or body weight. SIRT1 and HK2 expression displayed an age- and weight-dependent downregulation in controls, which was lost in IUGR pigs. Conversely, SIRT2 and GLUT4 were upregulated in IUGR pigs. Within the set of genes studied, we found a significant correlation between IGF-1 levels and gene expression in control, but not IUGR samples, indicating that lower IGF-1 may be a limiting factor in IUGR. IUGR-dependent gene alterations were partly linked to epigenetic changes on histone H3 acetylation and methylation. Overall, our data indicate that several sirtuins and metabolic genes display specific gene expression trajectories during fetal and early postnatal life. Gene expression alterations observed in IUGR are correlated to IGF-1 dysregulation. Given the importance of the genes studied in metabolic control, their perinatal alterations might contribute to the predisposition to metabolic disease of adulthood.

Abstract
Obesity, through low-grade inflammation, can drive insulin resistance and type 2 diabetes. While infiltration of adipose tissue (AT) with mononuclear cells (MNCs) is well established in obesity, the functional consequences of these interactions are less understood. Herein, we cocultured human adipose-derived stem cells (ASCs) from obese individuals with MNCs and analyzed their reciprocal behavior. Presence of ASCs 1) enhanced interleukin (IL)-17A secretion by Th17 cells, 2) inhibited γ-interferon and tumor necrosis factor α secretion by Th1 cells, and 3) increased monocyte-mediated IL-1β secretion. IL-17A secretion also occurred in stromal vascular fractions issued from obese but not lean individuals. Th17 polarization mostly depended on physical contacts between ASCs and MNCs-with a contribution of intracellular adhesion molecule-1-and occurred through activation of the inflammasome and phosphatidylinositol 3-kinase pathways. ASCs favored STAT3 over STAT5 transcription factor binding on STAT binding sites within the IL-17A/F gene locus. Finally, conditioned media from activated ASC-MNC cocultures inhibited adipocyte differentiation mRNA markers and impaired insulin-mediated Akt phosphorylation and lipolysis inhibition. In conclusion, we report that obese- but not lean-derived ASCs induce Th17 promotion and monocyte activation. This proinflammatory environment, in turn, inhibits adipogenesis and adipocyte insulin response. The demonstration of an ASC-Th17-monocyte cell axis reveals a novel proinflammatory process taking place in AT during obesity and defines novel putative therapeutic targets.
