The impacts of microbiome and microbiota-derived sodium butyrate on Drosophila transcriptome and metabolome revealed by multi-omics analysis
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. Overall design: Drosophila were reared in bacteria and sterile environment, respectively, and sodium butyrate was added to diet. Drosophila RNA-seq and midgut 16S rDNA were performed to study the effects of intestinal microflora and its metabolites on host transcription and metabolic regulation.
