Project name: Lactiplantibacillus plantarum

Description: Whole genome transcriptional profiling was used to characterize the response of Lactobacillus plantarum WCFS1 human isolate during challenge with hydroxytyrosol. Twelve independent experiments were performed and mixed at random in groups of four for total of three RNA samples. Whole genome transcriptional profiling was used to characterize the response of Lactobacillus plantarum WCFS1 human isolate during challenge with hydroxytyrosol. Twelve independent experiments were performed and mixed at random in groups of four for total of three RNA samples. The transcriptional profile reveals the induction of genes related to defense mechanisms against oxidative challenge. This response include genes related to inactivation of toxic oxygen radicals, probably derived from the autooxidation of hydroxytyrosol and genes involved in repairing the damage of oxygen radicals on proteins, including those involved in the metabolism of sulphur amino acids. Genes involved in peptidoglycan turnover, strenghthening of the cell wall and genes coding for osmoprotectants transporters, were downregulated. In addition, genes coding for elements typically involved in the stringent response, including ribosomal proteins, enzymes involved in the metabolism of the ppGpp alarmone, nitrogen metabolism, cell division and general stress proteins, were differentially regulated by hydroxytyrosol.Overall design: Biological triplicates: untreated cells: Control vs. Hydroxytyrosol treated cells: Experimental
