Project description:By combining directed evolution and synthetic biology, we engineered novel synthetic yeasts probiotics for the dynamic modulation of intestinal inflammation. In this experiment we treated TNBS-colitis induced mice with these probiotics and test the amelioration of immune response in the transcriptional level in the colon.

Project description:Purpose:Our data significantly advance understanding of Probiotics and Fructooligosaccharide regulatory mechanism in ileum of Taiping chicken Methods: Using RNA-seq analysis to study the gene expression in ileum tissue after Taiping chicken was given Probiotics and Fructooligosaccharide Results: A total of 164,629,826 and 149,883,266 raw reads were generated from the CT and MP_ FOS, respectively . After removing the interference data, about 164,028,872 and 149,364,852 clean reads were obtained Conclusions: through high-throughput sequencing of the six libraries from ileum of Taiping chicken, the expression level of mRNA has significant changes after given probiotics

Project description:Gemcitabine treatment shifts the intestinal microbiota of PC mice towards an inflammatory profile which may worsen mucositis and side effects observed upon chemotherapy. We explored the effect of a specific probiotics blend administered, with or without gemcitabine treatment, to PC xenografted mice.

Project description:In animal production the use of probiotics supplements to promote animal health is increasing. The objective of this study was to assess the impact of probiotics administration on global gene expression in dairy cows. Lactating Holstein Friesian cows (n=10) from the North Carolina Agricultural and Technical State University dairy herd were used for the study. Treatment was a 10 ml oral drench of FASTtrak microbial pack (Probiotics) (Conklin Company, Kansas City, MO) at the recommended dose in water or water only (control). This treatment was carried out for 60 days. Whole blood was collected at the beginning (Day 0) and end of the study (Day 60) for microarray analysis. We employed microarray expression profiling as a discovery platform to identify genes with potential association with probiotics supplementation in cows. Gene expression analysis identified 10,859 differentially expressed genes- 1168 upregulated genes and 9691 downregulated gene. Results for pathway analysis showed significant pathways associated with innate immunity such as the Toll-like receptor (TLR) pathway, inflammation response and Wingless (Wnt) signaling pathway. Real-time PCR was used to validate gene expression of members of the TLR and Wnt signaling pathway. Treatment affected the expression of innate and adaptive immune response, cytokine and Wnt pathway genes. Daily administration of probiotics to dairy cows impacts global gene expression and particularly the expression of innate immune genes in dairy cows. Ten animals were enrolled in the study and an initial blood sample was collected (Day 0). Animals (n=5) received either daily supplementations with FASTtrak microbial pack (Probiotics) (Conklin Company, Kansas City, MO) or water daily (control animals) for 60 days. Blood samples were collected at the end of the study from probiotics-treated and control animals for RNA extraction and microarray analysis. In vitro effect of lipopolysaccharide (LPS) endotoxin treatment was evaluated using blood samples collected from probiotics-treated animals (Day 60 samples) to serve as positive control array. A pooled sample was generated by taking equal concentration of RNA from experimental animals in each group. Pooled samples from each group was hybridized on Agilent one color bovine v2 bovine (v2) 4x44KÂ array slides.
