Enterococcus faecalis OG1RF vs. Δrel mutants under control or mupirocin-treated conditions

ABSTRACT: Transcriptional profiling to define the stringent response regulon and significance of basal (p)ppGpp levels in E. faecalis OG1RF. RNA was extracted from four replicate samples of each strain of interest and labeled with Cy3. For each replicate, labeled RNA was hybridized to slides along with Cy5-labeled reference RNA, extracted from E. faecalis OG1RF cells grown to mid-log.

Enterococcus faecalis OG1RF control vs. treatment with vancomycin

Project description:Transcriptional profiling to investigate the effect of drug treatment on the E. faecalis cells. For microarray analysis, E. faecalis OG1RF was grown in FMC medium supplemented with 10 mM glucose to an optical density at 600 nm (OD600) of 0.3 and the cultures were divided in 3 aliquots. One aliquot was collected by centrifugation and immediately frozen (untreated control cells). The other aliquots were treated for 30 or 60 min with 1.25 X the minimum inhibitory concentration (MIC) of vancomycin (10 M-NM-<g ml-1). After an exposure time of 30 or 60 minutes, each of these cultures was also centrifuged and the pellets frozen. RNA was then isolated from each pellet for microarray analysis. This process was repeated 3 additional times, for a total of four replicates of each condition. RNA was extracted from four replicate samples of each condition of interest (control cells grown to OD600 = 0.3 in FMC medium supplemented with 10mM glucose, then treated with vancomycin for 30 or 60 minutes) and labeled with Cy3. For each replicate, labeled RNA was hybridized to slides along with Cy5-labeled reference RNA, extracted from E. faecalis OG1RF cells grown in BHI medium to mid-log.

Enterococcus faecalis OG1RF control vs. treatment with ampicillin, bacitracin, or cephalothin

Project description:Transcriptional profiling to investigate the effect of drug treatment on the E. faecalis cells. For microarray analysis, E. faecalis OG1RF was grown in FMC medium supplemented with 10 mM glucose to an optical density at 600 nm (OD600) of 0.3 and the cultures were divided in 7 aliquots. One aliquot was collected by centrifugation and immediately frozen (untreated control cells). The other aliquots were treated for 30 or 60 min with 1.25 X the minimum inhibitory concentration (MIC) of one of the following CW inhibitors: ampicillin (20 Î¼g ml-1), bacitracin (80 Î¼g ml-1), or cephalothin (80 Î¼g ml-1). After an exposure time of 30 or 60 minutes, each of these cultures was also centrifuged and the pellets frozen. RNA was then isolated from each pellet for microarray analysis. This process was repeated 3 additional times, for a total of four replicates of each condition. RNA was extracted from four replicate samples of each condition of interest (control cells grown to OD600 = 0.3 in FMC medium supplemented with 10mM glucose, then treated with ampicillin, bacitracin, or cephalothin for 30 or 60 minutes) and labeled with Cy3.

Genome-wide Analysis of Enterococcus faecalis OG1RF Gene Expression During Infection

Project description:Changes in Enterococcus faecalis OG1RF gene expression during infection in a rabbit model of subdermal abscess formation were studied using microarray analysis. Samples assayed in arrays consisted of the input inoculum and total RNA collected from the subdermal chambers at 2 and 8 hours post-inoculation. Alexa647-labeled samples were co-hybridized with 0.5 micrograms of sheared OG1RF genomic DNA labeled with Cy3 as a standard reference between chips. Four biological replicates were performed for each of the 3 time points.
