Study Title | Polar metabolites in cecal tissue of mice treated with or without ampicillin and tributyrin |
Study Summary | The chromatin landscape integrates diverse cellular signals to regulate genome structure and subsequent biological functions, partly through posttranslational modifications (PTMs) on histone proteins. Many donor molecules for histone PTMs are metabolites and are therefore impacted by cellular metabolism and environmental cues. In this study, we aimed to investigate how chromatin and cellular metabolism are linked in the intestine. One class of metabolites in intestinal lumen is short chain fatty acids (SCFAs), which are generated by the commensal microbiota. We found that select histone PTMs (including acetylation, butyrylation, and propionylation) are located in intestinal epithelial cells and are dependent on the presence of microbes. Histone butyrylation is associated with active gene expression and regulated by the metabolite tributyrin, which increases metabolites related to butyrate metabolism and induces specific metabolic gene programs. Together, these studies demonstrate a physiological setting in which previously uncharacterized histone acylations are dynamically regulated through metabolites and associated with gene expression. |

Treatment:
Treatment ID: | TR003091 |
Treatment Summary: | Treatment groups are: vehicle-treated with mock gavage (Vehicle_Mock or VM), ampicillin-treated with mock gavage (Ampicillin_Mock or AM), or ampicillin-treated with tributyrin gavage (Ampicillin_Tributyrin or AT). In summary, mice were allowed to acclimate to water with 10g/L Splenda in drinking tubes for at least one day. Water was then switched to either Splenda alone (vehicle, n=5) or Splenda plus 1g/L ampicillin (Sigma catalogue# A1593; ampicillin, n=10). Mice were treated for seven days with this drinking water, and water was changed at least every several days. On day 7, mice were fasted for 4 hours and then gavaged with either 200 ul tributyrin (Sigma catalogue# W222305; n=5 of ampicillin treated group) or mock (25% glycerol, n=5 of ampicillin treated group and n=5 of vehicle treated group). Mice were sacrificed 6 hours following gavage for tissue harvesting. |
