Global transcriptional response to copper of Enterococcus faecalis wild-type and copY mutant

Project description:We examined the whole-genome transcriptional response of E. faecalis wild-type (WT) and copy mutant cells exposed to non toxic Cu excess. The analysis was focused in those genes which changed significantly their expression levels in the Cu-treated cells when compared to their untreated counterparts. The results indicated that after 3 h at 0.5 mM CuSO4, WT cells exhibited a significant increment of Cu content and the induction of three genes of cop operon along with other 142 genes. The comparison with the copY mutant exposed to Cu showed an extensive overlapping of transcriptional changes suggesting that other transcription factors may be mediating the response to Cu.

Transcriptome analysis of Enterococcus faecalis OG1 delta-EF2638 mutant

Project description:Analysis of changes in gene expression in Enterococcus faecalis OG1 delta-EF2638 mutant compared to wild-type OG1 strain. The deletion mutant has a growth defect when grown with aeration The mutant presented in this study is described and characterized in Vesic, D. and Kristich, C.J. 2012. A Rex-family transcriptional repressor influnces H2O2 accumulation by Enterococcus faecalis. (submitted for publication) Microarray analysis was done using RNA isolated from two independent cultures of wild-type Enterococcus faecalis OG1 and two independent cultres of Enterococcus faecalis OG1 delta-EF2638 mutant; each RNA sample was subjected to triplicate hybridization (technical replicates) . Microarrays were custom designed to investigate expression of ORFs in Enterococcus faecalis OG1RF genome. The arrays were designed based on the OG1RF annotation generated with the Rapid Annotation Using Subsystem Technology (RAST) server (Aziz et. al. 2008. BMC Genomics 9:75), as described in Frank et al (2012) Infect. Immun. 80:539. The aim was eighteen probe pairs per ORF, each of which is present in triplicate.

Enterococcus faecalis EfaR mutant transcriptome profile

Project description:Metal ions are important cofactors of inumerous enzymes and can interfere in many biological processes. Manganese is a particularly relevant metal as it is also involved in protection from oxidative stress and several Mn-dependent regulators have been shown to have a role in bacterial pathogenicity. A putative DNA-binding motif, here called efa motif was discovered in the promoter regions of genes previously shown to be differentially expressed in the presence of excess zinc, manganese and copper ions. This motif led to the finding and study of the genes putatively involved in the maintenance of manganese homeostasis in E. faecalis. In these genes is included the efaCBA operon, regulated by the Mn-dependent regulator EfaR. Other genes with this efa motif are shown to be regulated by EfaR. Regulation of these efa motif genes by EfaR is discussed as well as some clues on metal interaction with EfaR. Experiments mimicking conditions occurring on biological processes in the host showed that an EfaR plays an important role in biological processes crucial for E. faecalis colonization and virulence.
