Project description:Analysis of gene expression in Caco-2 intestinal epithelial cells stimulated with Bifidobacterium bifidum PRL2010. We used microarrays to investigate gene expression in intestinal epithelial cells in response to Bifidobacterium bifidum PRL2010, in particular genes involved in mucin pathways.

We used microarrays to investigate gene expression in intestinal epithelial cells in response to Bifidobacterium bifidum PRL2010, in particular genes involved in mucin pathways. Caco-2 cells were grown in transwell plates to 4 days post-confluence. Cells were then incubated for 2h and 4h with Bifidobacterium bifidum PRL2010. The experiment was performed in duplicate. Caco-2 RNA was extracted and hybridized to Affymetrix NuGO_Hs1a52018 arrays.
Project description:The purpose of this project was to determine the whole transcriptome response of Bifidobacterium bifidum SC555 to pooled and individual human milk oligosaccharides (HMO) relative to lactose
Project description:We studied the global transcription profiling of mouse upon colonization with Bifidobacterium bifidum PRL2010 by using DNA microarrays.
Project description:We have shown that pre-incubation with Bifidobacterium bifidum (B. bifidum) strain BF-1, a probiotic strain known to improve H. pylori-associated gastritis, suppresses the induction of IL-8 by the pathogen. To investigate how BF-1 affects gene expression in H. pylori-infected cells, we performed microarray analysis to assess gene expression in epithelial cells, which had been pre-incubated with BF-1 and infected with H. pylori.
Project description:We studied the global transcription profiling of human cell lines upon colonization with Bifidobacterium bifidum PRL2010 by using DNA microarrays.
Project description:We studied the global transcription profiling of human cell lines upon colonization with Bifidobacterium bifidum PRL2010 by using DNA microarrays. We decided to use HT29 monolayer as an in vitro model to investigate the molecular impact of B. bifidum PRL2010 on human intestinal transcriptome. HT29 monolayers cultivated at 15 days of post confluence were placed in contact with PRL2010 cells for a range of time spanning from 0 h, 1 h (T1), 2 h (T2) to 4 h (T4).

Four-condition experiment. Biological replicates with a dye-exchange experiment. Biological replicates with a longer incubation time experiment.
