Pharmacokinetic modeling and gene sequencing reveal the interplay between B vitamins and probiotics

ABSTRACT: The pharmacological significance of B vitamins, essential for various metabolic processes, and the therapeutic potential of probiotics in gastrointestinal health have been well-documented. However, the interactions between these entities remain poorly understood. In this study, we endeavored to elucidate the potential interplay between B vitamins and probiotics utilizing liquid chromatography-triple quadrupole mass spectrometry, pharmacokinetic modeling, and 16S rRNA gene sequencing. Employing healthy and pseudo-germ-free rat models, we revealed that probiotics significantly improve the absorption of B1, B3, B5, and B12, and that the gut microbiota played a mediating role in this enhanced absorption of B vitamins by probiotics. High-throughput genetic sequencing uncovered a synergistic effect of B vitamins and probiotics in modulating the gut microbiota, particularly increasing the abundance of Verrucomicrobia and Akkermansia. Furthermore, in vitro experiments demonstrated that probiotics used in this study had a relatively minor influence on the production and permeability of B vitamins, while B vitamins did not significantly contribute to the growth, auto-aggregation, and adhesion of probiotics. In summary, a complex network connection exists between B vitamins and probiotics, wherein the gut microbiota emerges as a pivotal factor that cannot be overlooked.

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.
