Project description:Promoting rumen development is closely related to the health and efficient growth of ruminants. We investigated the effect of sodium butyrate (SB) on rumen epithelium (RE), and whether the YAP1/TAZ-dependent alteration was involved in the RE developmental process induced by sodium butyrate. In the SB-treated cells, theYAP1/TAZ-dependent changes were not observed. SB increased the expression of genes involved in short-chain fatty acid (SCFA) metabolism, while YAP1/TAZ did not. Thus, SB mediated RE development was not associated with YAP1/TAZ.
Project description:A healthy rumen is crucial for normal growth and improved production performance of ruminant animals. Rumen microbes participate in and regulate rumen epithelial function, and the diverse metabolites produced by rumen microbes are important participants in rumen microbe-host interactions. SCFAs, as metabolites of rumen microbes, have been widely studied, and propionate and butyrate have been proven to promote rumen epithelial cell proliferation. Succinate, as an intermediate metabolite in the citric acid cycle, is a final product in the metabolism of certain rumen microbes, and is also an intermediate product in the microbial synthesis pathway of propionate. However, its effect on rumen microbes and rumen epithelial function has not been studied. It is unclear whether succinate can stimulate rumen epithelial development. Therefore, in this experiment, Chinese Tan sheep were used as experimental animals to conduct a comprehensive analysis of the rumen microbiota community structure and rumen epithelial transcriptome, to explore the role of adding succinate to the diet in the interaction between the rumen microbiota and host.
Project description:We performed global scale microarray analysis to identify detailed mechanisms by which sodium butyrate (SB) induce cell growth arrest and differentiation of colonic epithelial cells by using an Affymetrix GeneChip system. Colonic epithelial MCE301 cells used in this study were derived from transgenic mice harboring a tsSV40 large T-antigen. Arrested cell growth and a differentiated phenotype accompanying elevations of alkaline phosphatase activity and histone acetylation were observed in the cells treated with 2 mM SB. Of the 22,690 probe sets analyzed, approximately 2,000 genes were down- and up-regulated by a factor of 2.0 or greater in the cells treated with SB. Keywords: sodium butyrate, gene expression, colonic epithelial cell
Project description:As a histone deacetylase inhibitor, sodium butyrate and its derivative sodium phenylbutyrate involve in cellular events such as proliferation, differentiation, apoptosis and cell cycle control via reprogramming gene expression. However, the gene associated with the cell cycle control and molecular signaling triggering cell apopotosis and death are not well elucidated. Here, we treated A549 cells,a cell line belong to the non-small cells lung cancer,with high concentration of sodium butyrate or sodium phenylbutyrate and then used microarray identified differentially-expressed mRNA during this process.
Project description:The Madin-Darby bovine kidney epithelial cells, when at approximately 50% confluence (during the exponential phase), were treated with 10mM sodium butyrate for 24h. Butyrate induced profound changes in gene expression related with multiple signal transduction pathways such as cell cycle control, apoptosis and extracellular matrix remodeling in this cell line Keywords: stress response, two class unpaired design
Project description:As a histone deacetylase inhibitor, sodium butyrate involves in cellular events such as proliferation, differentiation,apoptosis and cell cycle control via reprogramming gene expression. However, the target genes associated with the cell cycle control and molecular signaling triggering cell apopotosis and death are not well elucidated.
Project description:Rumen epithelial parakeratosis, a common disease in ruminants caused by abnormalities in the ruminal stratified squamous epithelial keratinization process, negatively impacts ruminant health and performance. While we still lack a comprehensive perception of the underlying mechanisms and the predisposing factors for this disorder.Here, we investigated rumen epithelial cell heterogeneity, differentiation trajectories, and cornification to clarify the rumen epithelial keratinization process
Project description:Analysis of colorectal cancer (CRC) cell line HT-29 treated with Sodium Butyrate. Sodium Butyrate, a HDAC inhibitor present in gut, can differentiate the undifferentiated HT-29 to enterocytes by the induction of brush border enzyme alkaline phosphatase. Results provide the transcriptional profiling underlying the butyrate-induced differentiation of CRC.
Project description:We analyzed a role of histone deacetylases in alternative splicing regulation. Using human exon arrays we identified a list of 683 genes whose splicing changes after HDAC inhibition with sodium butyrate. 6 samples (3 nontreated controls and 3 sodium butyrate treated cells)
Project description:Promoting rumen development is closely related to the health and efficient growth of ruminants. In the present study, we aimed to assess the impact of YAP1/TAZ on RE proliferation. The transcriptomic expression was analyzed to investigate the potential regulatory networks. The results indicated that GA promoted RE cell proliferation, while VP disrupted RE cell proliferation. The Hippo, Wnt, and calcium signaling pathways were altered in cells following the regulation of YAP1/TAZ. Upon YAP1/TAZ activation through GA, the CCN1/2 increased to promote RE cell proliferation. While when the YAP1/TAZ was inhibited by VP, the BIRC3 decreased to suppress RE cell proliferation. Thus, YAP1/TAZ may be potential targets for regulating RE cell proliferation. These findings broaden our understanding of the role of YAP1/TAZ and their regulators in RE and offer a potential target for promoting rumen development.
