[PMID: 37509173 PMCID: PMC10377523 DOI: 10.3390/biom13071137] [Citation(s) in RCA: 2] [Impact Index Per Article: 2.0] [Reference Citation Analysis] [Abstract] [Key Words] [Track Full Text] [Journal Information] [Subscribe] [Scholar Register] [Received: 04/24/2023] [Revised: 07/12/2023] [Accepted: 07/13/2023] [Indexed: 07/30/2023] Open
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.

Short-chain fatty acid-butyric acid ameliorates granulosa cells inflammation through regulating METTL3-mediated N6-methyladenosine modification of FOSL2 in polycystic ovarian syndrome. Clin Epigenetics 2023; 15:86. [PMID: 37179374 PMCID: PMC10183145 DOI: 10.1186/s13148-023-01487-9] [Citation(s) in RCA: 3] [Impact Index Per Article: 3.0] [Reference Citation Analysis] [Abstract] [Key Words] [Grants] [Journal Information] [Subscribe] [Scholar Register] [Received: 03/06/2023] [Accepted: 04/19/2023] [Indexed: 05/15/2023] Open
Abstract
Polycystic ovary syndrome (PCOS) is an endocrine and metabolic disorder characterized by chronic low-grade inflammation. Previous studies have demonstrated that the gut microbiome can affect the host tissue cells' mRNA N6-methyladenosine (m6A) modifications. This study aimed to understand the role of intestinal flora in ovarian cells inflammation by regulating mRNA m6A modification particularly the inflammatory state in PCOS. The gut microbiome composition of PCOS and Control groups was analyzed by 16S rRNA sequencing, and the short chain fatty acids were detected in patients' serum by mass spectrometry methods. The level of butyric acid was found to be decreased in the serum of the obese PCOS group (FAT) compared to other groups, and this was correlated with increased Streptococcaceae and decreased Rikenellaceae based on the Spearman's rank test. Additionally, we identified FOSL2 as a potential METTL3 target using RNA-seq and MeRIP-seq methodologies. Cellular experiments demonstrated that the addition of butyric acid led to a decrease in FOSL2 m6A methylation levels and mRNA expression by suppressing the expression of METTL3, an m6A methyltransferase. Additionally, NLRP3 protein expression and the expression of inflammatory cytokines (IL-6 and TNF-α) were downregulated in KGN cells. Butyric acid supplementation in obese PCOS mice improved ovarian function and decreased the expression of local inflammatory factors in the ovary. Taken together, the correlation between the gut microbiome and PCOS may unveil crucial mechanisms for the role of specific gut microbiota in the pathogenesis of PCOS. Furthermore, butyric acid may present new prospects for future PCOS treatments.

How to Obtain a Mega-Intestine with Normal Morphology: In Silico Modelling of Postnatal Intestinal Growth in a Cd97-Transgenic Mouse. Int J Mol Sci 2021; 22:ijms22147345. [PMID: 34298973 PMCID: PMC8305140 DOI: 10.3390/ijms22147345] [Citation(s) in RCA: 0] [Impact Index Per Article: 0] [Reference Citation Analysis] [Abstract] [Key Words] [MESH Headings] [Download PDF] [Figures] [Journal Information] [Subscribe] [Scholar Register] [Received: 06/01/2021] [Revised: 06/29/2021] [Accepted: 07/02/2021] [Indexed: 11/19/2022] Open
Abstract
Intestinal cylindrical growth peaks in mice a few weeks after birth, simultaneously with crypt fission activity. It nearly stops after weaning and cannot be reactivated later. Transgenic mice expressing Cd97/Adgre5 in the intestinal epithelium develop a mega-intestine with normal microscopic morphology in adult mice. Here, we demonstrate premature intestinal differentiation in Cd97/Adgre5 transgenic mice at both the cellular and molecular levels until postnatal day 14. Subsequently, the growth of the intestinal epithelium becomes activated and its maturation suppressed. These changes are paralleled by postnatal regulation of growth factors and by an increased expression of secretory cell markers, suggesting growth activation of non-epithelial tissue layers as the origin of enforced tissue growth. To understand postnatal intestinal growth mechanistically, we study epithelial fate decisions during this period with the use of a 3D individual cell-based computer model. In the model, the expansion of the intestinal stem cell (SC) population, a prerequisite for crypt fission, is largely independent of the tissue growth rate and is therefore not spontaneously adaptive. Accordingly, the model suggests that, besides the growth activation of non-epithelial tissue layers, the formation of a mega-intestine requires a released growth control in the epithelium, enabling accelerated SC expansion. The similar intestinal morphology in Cd97/Adgre5 transgenic and wild type mice indicates a synchronization of tissue growth and SC expansion, likely by a crypt density-controlled contact inhibition of growth of intestinal SC proliferation. The formation of a mega-intestine with normal microscopic morphology turns out to originate in changes of autonomous and conditional specification of the intestinal cell fate induced by the activation of Cd97/Adgre5.

Abstract
Toxin A (TcdA) and toxin B (TcdB), the two exotoxins of Clostridium difficile, are main causal agents for the colonic epithelium damage in Clostridium difficile infection (CDI). The Hippo pathway is crucial for the control of tissue homeostasis and regeneration of intestines. However, the dysregulation of Hippo pathway in CDI is unclear. Here we show that YAP and TAZ, the transcriptional coactivators downstream of the Hippo pathway, are sequestered in the cytoplasm, degraded, and inactivated by treatment with TcdA and TcdB in colonic epithelial cells. The overexpression of YAP restores the messenger RNA expressions of YAP target genes, attenuates the disruption of cytoskeleton and cell rounding, and rescues the cell proliferation of colonic epithelial cells under exposure of the two toxins. Our results demonstrate that inhibition of YAP and TAZ is involved in the pathogenesis of CDI, implicating that increasing YAP activity could be a potential therapeutic strategy for the CDI treatment.

Am J Clin Nutr 2019; 109:1112-1118. [PMID: 30924493 DOI: 10.1093/ajcn/nqy367] [Citation(s) in RCA: 20] [Impact Index Per Article: 4.0] [Reference Citation Analysis] [Abstract] [Key Words] [Track Full Text] [Journal Information] [Subscribe] [Scholar Register] [Received: 06/05/2018] [Accepted: 12/03/2018] [Indexed: 02/06/2023] Open
Abstract
BACKGROUND The main cause of intestinal failure is short bowel syndrome (SBS). The management goal for children with SBS is to promote intestinal adaptation while preserving growth and development with the use of parenteral nutrition (PN). OBJECTIVES This study evaluated the intestinal absorption rate in children with SBS, focusing on the role of the remnant colon. In addition, the relation between intestinal absorption rate, citrulline concentration, and small bowel length was studied. METHODS Thirty-two children with SBS on PN were included. They were divided into 3 groups according to the European Society for Clinical Nutrition and Metabolism (ESPEN) anatomical classification system: type 1 SBS (n = 9), type 2 (n = 13), and type 3 (n = 10). Intestinal absorption rate was assessed by a stool balance analysis of a 3-d collection of stools. Plasma citrulline concentrations were measured and the level of PN dependency was calculated. RESULTS The total energy absorption rate did not differ significantly between the 3 groups: 68% (61-79% ) for type 1, 60% (40-77%) for type 2, and 60% (40-77%) for type 3 ( P = 0.45). Children with type 2 or 3 SBS had significantly shorter small bowel length than children with type 1: 28 cm (19-36 cm) and 16 cm (2-29 cm), respectively, compared with 60 cm (45-78 cm) ( P = 0.04). Plasma citrulline concentrations were lower in type 3 SBS but not significantly different: 15 µmol/L (11-25 µmol/L) in type 1, 14 µmol/L (7-21 µmol/L) in type 2 , and 9 µmol/L (6-14 µmol/L) in type 3 ( P = 0.141). A multivariate analysis confirmed the role of the remnant colon in providing additional energy absorption. CONCLUSION This study demonstrated the importance of the colon as a salvage organ in children with SBS. Plasma citrulline concentrations should be interpreted according to the type of SBS. Efforts should focus on conservative surgery, early re-establishment of a colon in continuity, and preserving the intestinal microbiota.
