MiRNAs expression in swine monocytes stimulated with Bifidobacterium animalis ssp. lactis Bb12

ABSTRACT: Bifidobacterium animalis ssp. lactis Bb12 (Bb12) is a probiotic bacteria with several reported benefits, including immunomodulatory capacity. This is due to the bacteria recognition by receptors such as TLR2, which in turn affects the miRNA transcriptome of immune system cells. We aimed to analyze miRNA expression in swine monocytes stimulated with Bb12, and their expression when TLR2 receptor is blocked. A microarray containing 407 porcine unique miRNA probes was employed to identify differences in the miRNA expression pattern in swine monocytes in response to Bb12. A total of 143 were differentially expressed miRNAs (p<0.05); out of which, 87 miRNAs are statistically significant but have lower signals (signal <500).

Expression data from Bifidobacterium animalis ssp. lactis strains exposed to hydrogen peroxide stress

Project description:Stress survival tactics in bacteria utilize the up- and down-regulation of stress response genes. In bacteria that lack classical stress response genes for oxidative stress, other cellular systems can be used for cell survival. We used custom microarrays to study the regulation of genes in Bifidobacterium animalis ssp. lactis strains to oxidative stress to elucidate novel stress response mechanisms. Bifidobacterium cells were grown to late log phase then harvested and exposed to a sub-lethal level of hydrogen peroxide. Samples were taken at 5 and 20 mins for RNA extraction and hybridization on Affymetrix microarrays. Controls were prepared for each time point which recieved no hydrogen peroxide treatment.

Comprehensive genomic, phenotypic and transcriptomic approaches to enhance Bifidobacterium animalis subsp. animalis growth and survival in milk

Project description:Bifidobacterium animalis subsp. animalis CNCM I-4602 was tested for its ability to grow in reconstituted skimmed milk (RSM). Strain CNCM I-4602 grows and survives poorly in reconstituted skimmed milk (RSM), although this was partially countered by the addition of certain compounds, including yeast extract, uric acid, glutathione, cysteine, ferrous sulfate and a combination of magnesium sulfate and manganese sulfate. Microarray analysis of the strain grown in RSM revealed a number of up-regulated amino acid biosynthetic pathways, as well as stress-related genes. Expression profiling by array

Transcriptional and functional analysis of Bifidobacterium animalis subsp. lactis exposure to tetracycline

Project description:Commercial probiotic bacteria must be tested for acquired antibiotic resistance elements to avoid potential transfer to pathogens. The European Food Safety Authority recommends testing resistance using microdilution culture techniques previously used to establish inhibitory thresholds for the Bifidobacterium genus. Many Bifidobacterium animalis subsp. lactis strains exhibit increased resistance to tetracycline, historically attributed to the ribosomal protection gene tet(W). However, some strains that harbor genetically identical tet(W) genes show various inhibition levels suggesting that other genetic elements also contribute to observed differences. Here, we adapted several molecular assays to confirm the inhibition of B. animalis subsp. lactis strains Bl-04 and HN019, and employed RNA-seq to assess the transcriptional differences related to genomic polymorphisms. We detected specific stress responses to the antibiotic by correlating ATP concentration to viable genome copies from droplet digital PCR, and found that the bacteria were still metabolically active in high drug concentrations. Transcriptional analyses revealed that several polymorphic regions, particularly a novel multi-drug efflux transporter, were differentially expressed between the strains in each experimental condition, likely having phenotypic effects. We also found that the tet(W) gene was up-regulated only during sub-inhibitory tetracycline concentrations, while two novel tetracycline resistance genes were up-regulated at high concentrations. Furthermore, many genes involved in amino acid metabolism and transporter function were up-regulated while genes for complex carbohydrate utilization, protein metabolism, and CRISPR-Cas systems were down-regulated. These results provide high-throughput means for assessing antibiotic resistance and determine the genetic network that contributes to the global tetracycline response between two highly related probiotic strains.

Expression data from Caco-2 cells co-cultivated with B. animalis subsp. lactis BB-12

Project description:Although intestinal microbiota play a pivotal role in the development of host immune system this biological issue was not so far studied in great detail. In this study we examined immune response of Caco-2 enterocytes after incubation with common probiotic Bifidobacterium animalis subsp. lactis BB-12 for 4 hours. We used microarrays to inspect the global gene expression of Caco-2 cells upon co-culturing with B. animalis subsp. lactis BB-12 and several distinct immune-related genes up-regulated during this process.
