The impacts of microbiome and microbiota-derived sodium butyrate on Drosophila transcriptome and metabolome revealed by multi-omics analysis
Ontology highlight
ABSTRACT: Drosophila melanogaster was used to investigate the influence of microbiota-derived intestinal flora and its metabolites on host transcriptional regulation by adding sodium butyrate to a sterile diet for constructing a sterile Drosophila model. In order to further investigate the effects of sodium butyrate on Drosophila melanogaster at the molecular mechanism level, we detected the abundance and composition of midgut microbial colonies based on 16S rRNA gene sequences, and analyzed the overall structure and metabolic activities of host transcriptional networks by combining transcriptome and non-target metabolomics data.

Project description:To assess the effect of sodium butyrate exposure on human ESC grown without culture support for self-renewal (I.e. without conditioned medium and added bFGF) - three groups were compared - H1 culture in feeder conditioned medium vs without conditioned medium in 0.2 mM sodium butyrate vs. grown in sodium butyrate for 4 passages followed by return to conditioned medium conditions for 3 passages. The three groups were grown in triplicate and compared on Agilent whole human genome array
Project description:To assess the effect of sodium butyrate exposure on human ESC grown without culture support for self-renewal (I.e. without conditioned medium and added bFGF) in support of data generated on H1 hESC - two groups were compared - BG02 culture in feeder conditioned versus on sodium butyrate - in triplicate and compared on Agilent whole human genome array

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:Butyrate has been proposed as a drug therapy by acting as a lysine deacetylase (KDAC) inhibitor and elevating protein acetylation, in particular on histones. Nonetheless, recent studies suggest that tissues such as the gut can utilize butyrate as a metabolite. We have previously shown that the addition of butyrate induces a rapid increase of oxygen consumption in whole Drosophila melanogaster heads. Here we show that while head oxygen consumption is increased by the addition of butyrate, no apparent changes are observed on the proteome and acetylome. Instead, we show that butyrate is metabolized and incorporated into the tricarboxylic acid (TCA) cycle. Collectively our data supports the notion that the therapeutic benefits of acute butyrate treatment may be also mediated by improving metabolic rates, rather than solely targeting the epigenome or acetylome.
Project description:To assess the effect of sodium butyrate exposure on mouse ESC grown without self-renewal support (I.e. without feeders or LIF) - these cells were compared to cells grown without sodium buytrate, but with added mouse LIF via Agilent whole mouse genome array
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:To assess the effect of sodium butyrate exposure on human ESC grown without culture support for self-renewal (I.e. without conditioned medium and added bFGF) - three groups were compared - H1 culture in feeder conditioned medium vs without conditioned medium in 0.2 mM sodium butyrate vs. grown in sodium butyrate for 4 passages followed by return to conditioned medium conditions for 3 passages. The three groups were grown in triplicate and compared on Agilent whole human genome array Experiment Overall Design: H1 hESC were grown under 3 conditions: A. 48 passages total, the last 9 passages off of feeders on Matrigel in feeder conditioned medium B. 48 passages total, within the last 9 passges, #39-41 were in conditioned medium and #42-48 were without conditioned medium and added bFGF but with 0.2 mM sodium butyrate on Matrigel C. 49 passages total, within the last 10 passages #39-41 were in conditioned medium, #42-46 in 0.2 mM sodium butyrate (without feeder of bFGF support) and #47-49 back to conditioned medium + bFGF. The RNA from these cells were compared via Agilent whole human genome array.
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 aim of this study was to evaluate the effects of sodium butyrate enemas on the mucosal genes expression profiles of patients with an enterostomy.
