Project description:Investigation of transcriptomic changes in M.luteus at 12hrs and 24hrs. Differences in fatty acid profiles of M. luteus at exponential and stationary phase is attributed to transcriptional changes of branched amino acid biosynthesis and degradation genes. This study is described by Pereira, J.H., E.B. Goh, J.D. Keasling, H.R. Beller and P.A. Adams in Crystal structure of FabH and factors affecting the distribution of branched fatty acids in Micrococcus luteus, which has been submitted to Acta Crystallographica Section D A 6 microarray study using total RNA recovered from six separate control cultures of Micrococcus luteus NCTC2665 strain with 3 harvested after 12hrs of growth and the other 3 after 24hrs of growth. Each chip measures the expression level of 2,374 ORF based on the draft genome sequence of Micrococcus luteus with ten 60-mer probe pairs (PM/MM) per gene, with 3-fold technical redundancy.

Project description:Differential transcriptomic responses of Biomphalaria glabrata (Gastropoda, Mollusca) to bacteria and metazoan parasites Schistosoma mansoni and Echinostoma paraensei (Digenea, Platyhelminthes). Transcriptional profiling of Biomphalaria glabrata comparing control uninfected M-line B. glabrata with five experimental groups. The experimental groups are: wounded but not infected M-line, Escherichia coli infected, Micrococcus luteus infected, Echinostoma paraensei infected and Schistosoma mansoni infected at 12 hours time point post infection.
Project description:Within the scope of a technical note we tested our MetaProteomeAnalyzer Portable software workflow on experimental data sets from samples with known composition. For generating a benchmarking data set, the bacterial strains (5BCT) Bacillus subtilis, Escherichia coli, Pseudomonas fluorescens, Micrococcus luteus and Desulfovibrio vulgaris were mixed with a protein ratio of 1:1:1:1:1.
Project description:Transcriptome profiling of immune-responsive genes in Drosophila melanogaster during Gram-positive bacterial infection was performed. The most highly induced gene by Micrococcus luteus infection was a novel gene CG44404, named Induced by Infection (IBIN). In the Flybase release FB2019_4 (22.8.2019) IBIN is annotated as coding for a short peptide. In the transcriptome analysis, fourteen immune-inducible long non-coding RNA (lncRNA) genes (Fold Change > 3) were also found.

Transcriptional profiling of Biomphalaria glabrata comparing control uninfected M-line B. glabrata with five experimental groups. The experimental groups are: wounded but not infected M-line, Escherichia coli infected, Micrococcus luteus infected, Echinostoma paraensei infected and Schistosoma mansoni infected at 12 hours time point post infection. Seven groups of samples: two controls, wounded, two bacterial- and two trematode-infected B. glabrata were analyzed in triplicate, using universal RNA reference.
Project description:Transcriptome profiling of immune-responsive genes in Drosophila melanogaster during Gram-positive bacterial infection and upon silencing of osa was performed. The most highly induced gene in the control set (150071 Valanne I) by Micrococcus luteus infection was CR44404, and its expression is fully dependent on osa expression (as shown in this dataset, 150071 Valanne II). The full transcriptome analysis also indicated that Osa regulates the expression of immune genes by modifying the expression of the Drosophila NF-kappaB factors Relish and Dif.
Project description:The importance of the impact of human hormones on commensal microbiota and microbial biofilms is established in lots of studies. In the present investigation, we studied the proteome of the biofilm matrix of the commensal actinobacterium Micrococcus luteus C01. In our investigation, we tested the effect of epinephrine in concentration 4.9×10-9 M on immature (24 h ) and mature (72 h) biofilms in comparison with controls without the hormone administration. We investigated the temporal changes in the matrix proteome during the incubation in control samples and in samples with epinephrine.
