Project description:Transcriptional profiling of 25d old piglets comparing control untreated suckling jejunum with weaned piglets' jejunum. The goal was to gain new insight into the interaction between weaning and intestinal function.A keen interest is paid in deciphering expression changes of apoptosis or cell cycle control genes. The statistical analysis of gene ontology revealed that most of these altered genes are metabolic-related enzymes and regulators which may involved in the biological regulation, developmental process, and cellular process. Weaning also causes alterations in various immune response pathways. Results likely indicate that weaning induced cell cycle arrest, enhanced apoptosis, and inhibited cell proliferation. Two-condition experiment, suckling control piglets' jejunum vs. weaned piglets' jejunum. Biological replicates: 4 control replicates, 4 weaned replicates.

Project description:<p><strong>BACKGROUND:</strong> Dietary intervention has been reported to improve intestinal health. The intestinal microbiota of newborn animals plays a fundamental role in the development of intestinal function and the innate immune system. However, little is currently known about dietary interventions in the gut microbiota and barrier function of livestock, especially suckling Bamei piglets. To this end, we studied the effect of early dietary supplementation on intestinal bacterial communities and intestinal barrier function in piglets.</p><p><strong>RESULTS:</strong> 10 purebred Bamei sows were randomly allocated into two groups. In group one, the piglets received a supplementary milk replacer on day 7 of age, whereas the other control group was allowed sow’s milk alone. At 21 days, 18 and 17, respectively, piglets in each group of average weight were randomly selected and sacrificed. Tissue and digesta samples were collected from the jejunum to evaluate differences in the microbiome-metabolome and the mRNA expression of inflammatory cytokines (TLR4, TNFα and IL-8) and barrier proteins (ZO-1, Occludin and Claudin-1). Sequencing of 16S rRNA revealed that ES improved the gut microbiome composition of Bamei suckling piglets. The relative abundances of some bacterial species such as Lactobacillales, Romboutsia, Actinobacillus, Bacteroides were significantly reduced in the ES group. Metabolomics analysis indicated that 23 compounds were enriched and 35 compounds decreased in the ES group. And correlation analysis demonstrated that some gut bacterial genera were highly correlated with altered gut microbiota-related metabolites. Meanwhile, ES of Bamei suckling piglets altered the gene expression of inflammatory cytokine and barrier protein in the jejunum.</p><p><strong>CONCLUSIONS:</strong> In summary, these results provide important insights on the relationships between jejunal microbiota and related metabolites, and jejunal barrier function during the early life of Bamei suckling piglets.</p>

Project description:Gene expression profiles from pig jejunum scrapings either fed or fasted at four and six weeks of age (n=16 per group). Result indicate that the fasting intervention was more severe in the four-week-old piglets, but also induced changes functinal changes in especially metabolic function and cell proliferation in the six-week-old piglets.

Project description:Somatic cell nuclear transfer has brought considerable chances to breed excellent breeds and protect endanger animals, while also produced numerous fail embryos and abnormal individuals due to inefficient epigenetic modification at the same time. To understand some mechanisms of abnormal piglets with phenotypes such as macroglossia, standing and walking disabilities in our study and find some differences between abnormal piglets and conventionally bred normal piglets, DNA methylation profile and genome-wide gene expression were conducted in two groups, using methylated DNA immunoprecipitation binding highthroughput sequencing (MeDIP-Seq) and RNA sequencing(RNA-Seq). We generated and provided a genome-wide DNA methylation and gene expression profile for abnormal cloned and conventionally bred piglets. We detected a total of 1493 genes differentially expressed in two groups and 382 of these genes also differentially methylated in two groups. Analysis of relationship between DNA methylation and gene expression revealed that DNA methylation levels had significantly negative and monotonic correlation with gene expression levels in particular regions of genes while no obvious monotonic correlation in other regions. Besides, we found some interesting genes and pathways such as MYH7 and mTOR signalling pathway that may played essential role in muscle growth and development. Briefly, these results provide reliable data for future epigenetic studies and may help to uncover the mechanism of failure clones via SCNT. We dissected the leg muscle from the cloned piglets and the conventionally bred piglets, and analyzed the difference of MeDIP-seq and RNA-seq between the two groups. As for data of abnormal cloned piglets, we downloaded it from GEO under Super-Series accession No. GSE51477, including SubSeries accession No.GSE51282 for RNA-seq data (No. GSM1241829 for abnormal cloned group) and SubSeries accession No. GSE51476 for MeDIP-seq data (No. GSM1246252 for abnormal cloned group).
