Project description:Microbiome DNA from the adhering fraction of a sheep rumen. The RSTs were generated using an improved version of SARST (referred to as iSARST) from the microbiome DNA extracted from the adhering fraction of the rumen content taken from a sheep. The iSARST method is going to be submitted to Nature Biotechnology for publication. Keywords: other
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:In the present study, we studied the effect of dietary selenium (Se) supplementation on the transcriptomic profile of sheep. The main objective was to evaluate the effect of Se-supplementation on the overall transcriptome of sheep, the altered pathways, and the biological processes related to it . A custom oligo microarray platform (AMADID: 070119) was designed, then used to profile gene expression from 20 samples from 10 sheep at two time points (T0; before Se-supplementation, and T40; at the end of a 40-d Se-supplementation period). Isolated and purified total RNAs were individually hybridized to the custom (4x44k) DNA microarray. The comparison of control and treated animal transcriptomes revealed a large set of differentially expressed genes. After functional analysis and qPCR validation, the result showed several pathways and biological processes that have been altered following Se-supplementation to the diet.
