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:Emerging data has highlighted the importance of short-chain fatty acids (SCFAs), particularly butyrate, in regulating ruminal homeostasis in vivo isolated epithelial cells. However, little is known about other SCFAs like acetate or propionate, and the interaction between rumen microbes and epithelial immunity are rarely reported. Here, we firstly combined infusion of three SCFAs, to study their different roles in ruminal development, antioxidant capacity, barrier functions, and immunity, as well as cross-talk with ruminal microbiome (16S rRNA sequencing data of rumen digesta) and derived transcriptome (RNA-Seq) and metabolism using an in vivo goat model.

Project description:As the unique organ, rumen plays vital roles in providing products for humans, however, the underlying cell composition and interactions with epithelium-attached microbes remain largely unknown. Herein, we performed an integrated analysis in single-cell transcriptome, epithelial microbiome, and metabolome of rumen tissues to explore the differences of microbiota-host crosstalk between newborn and adult cattle models. We found that fewer epithelial cell subtypes and more abundant immune cells (e.g., Th17 cells) in the rumen tissue of adult cattle. Metabolism-related functions and oxidation-reduction process were significantly upregulated in the adult rumen epithelial cell subtypes. The epithelial Desulfovibrio was significantly enriched in the adult cattle. To further clarify the role of Desulfovibrio in host’s oxidation-reduction process, we performed metabolomics analysis of rumen tissues and found that Desulfovibrio showed a high co-occurrence probability with the pyridoxal in the adult cattle compared with newborn ones. The adult rumen epithelial cell subtypes also showed stronger ability of pyridoxal binding. These indicates that Desulfovibrio and pyridoxal likely play important roles in maintaining redox balance in adult rumen. The integrated analysis provides novel insights into the understanding of rumen function and facilitate the future precision improvement of rumen function and milk/meat production in cattle.

Project description:The purpose of this study was to determine the effects of normal diet feed (NF) and alternative diet feed (AF) on animal performance, gene expression in adipose, liver, and muscle, and changes in bacteria and fungi in the rumen of Bos-Taurus using high-throughput sequencing methods. In addition, Interactions between differentially expressed genes (DEGs) in major metabolic organs and rumen bacteria /fungi were studied. A total of 34,360 genes were found to be expressed across all tissues examined based on transcriptome analysis. According to our findings, 34, 36, 28 genes were differentially expressed in the adipose, liver, and muscle tissues, respectively. A majority of DEGs identified were related to osteoclast differentiation, phagosomes, and immune-functions etc. A study of rumen samples revealed that Firmicutes and Bacterioidetes were the most common phyla. An AF diet significantly increased Firmicutes abundance and reduced Bacterioidetes abundance (p< 0.05). Genus-level analysis revealed that the occurrence of Faecalicatena, Intestinimonas, Lachnoclostridium, Faecalicatena, and Intestinimonas was higher (p < 0.05) in animals fed with the AF diet than in animals fed with an NF diet. As for fungi, Neocallimastigomycota accounted for 98.2% of the NF diet and 86.88% of the AF diet. The AF increased the abundance of Orpinomyces (21.15% to 29.7%), Piromyces (0.1% to 1.8%), and other fungi, but reduced the abundance of Neocallimastix (72.0% to 25.2%). Analysis of the correlation between DEGs and microbes showed that rumen bacteria/fungi significantly influenced expression levels of genes in adipose, liver, and muscle tissues

Project description:The time-resolved impact of monensin on the active rumen microbiome in a rumen-simulating technique (Rusitec) was studied with metaproteomic and metabolomic approaches. Upon monensin treatment, decreased catabolism linked to fiber degradation was observed by the reduced abundance of proteins assigned to fibrolytic bacteria and glycoside hydrolases, sugar transporters and carbohydrate metabolism. Reduced amounts of ammonium as well as branched-chain fatty acids pointed towards a decreased proteolytic activity. The family Prevotellaceae exhibited increased resilience in the presence of monensin, with a switch of metabolism from acetate to succinate production. Prevotella species harbor a membrane bound electron transfer complex, which drives the reduction of fumarate to succinate, the substrate for propionate production in the rumen habitat. Besides the increased succinate production, a concomitant depletion of methane concentration was observed upon monensin exposure. Our study demonstrates that Prevotella sp. shifts its metabolism successfully in response to monensin exposure and Prevotellaceae represents the key bacterial family stabilizing the rumen microbiota during exposure to monensin.
