Transcription profiling of S. cerevisiae response to tomatidine treatment

ABSTRACT: Genome-wide expression profiling was used to identify genes that showed altered expression in response to treatment with the fungistatic saponin tomatidine. Overnight batch cultures of strain S288C were diluted to an optical density at 600nm of 0.1. After 1 hour of growth at 30Â°C, the compounds were added and the cultures were incubated for an additional 5 hours prior to harvesting. Control cultures were treated with the solvent dimethylformamide (DMF). Tomatidine treated cultures were grown in the presence of tomatidine (dissolved in DMF) at concentations of 7.5 uM and 15 uM. Growth inhibition by the compounds was monitored by measuring the OD600nm. Cells were pelleted and frozen in liquid nitrogen. Acid-washed glass beads (0.5 mm diameter; Sigma) were added and the cells disrupted using two 20 s cycles at speed setting 6 in the Savant Bio 101 Fast Prep FP120. Total RNA was isolated using the Qiagen RNeasy kit (Qiagen, Inc., Valencia, CA, USA). Microarray hybridisation was performed using the Affymetrix GeneChipÂ® Yeast genome S98 array using protocols described by Affymetrix, Inc. (Santa Clara, CA, USA) (as previously described (Zhu et al., 2001). Data were analyzed using AffymetrixÂ® Microarray Suite version 5.0 software

Experiment Overall Design: Overnight batch cultures of strain S288C were diluted to an optical density at 600nm of 0.1. After 1 hour of growth at 30Â°C, the compounds were added and the cultures were incubated for an additional 5 hours prior to harvesting. Control cultures were treated with the solvent dimethylformamide (DMF). Tomatidine treated cultures were grown in the presence of 0.625 ppm tomatidine, 13.9 ppm Tomatine and 0.313 ppm Fenpropimorph, all dissolved in DMF. Each of the three replicates of the cultures produced on 3 independent days.

P. aeruginosa and indole and 7-hydroxyindole

Project description:We used DNA microarrays to investigate the impact of indole and 7-hdroxyindole on P. aeruginosa PAO1.For the microarray experiments, 10 g glass wool (Corning Glass Works, Corning, N.Y.) were used to form biofilms in 250 mL in 1 L Erlenmeyer shake flasks which were inoculated with overnight cultures of P. aeruginosa PAO1 diluted that were 1:100. For P. aeruginosa with 7-hydroxyindole and indole, 500 uM 7-hydroxyindole in 250 uL DMF, 1000 uM indole in 250 uL DMF, or 250 uL DMF alone were added to cells grown in LB. The cells were shaken at 250 rpm and at 37oC for 7 h to form biofilms on the glass wool, and RNA was isolated from the biofilm cells.

Pseudmonas aeruginosa PAO1 wild-type and delta prpC cultured on MOPS Succinate and MOPS Succinate + Propionate

Project description:Pseudomonas aeruginosa strain PAO1 (wild-ype and prpC) was grown in 40 ml MOPS with succinate as the sole carbon source, 37 °C with shaking (250 rpm) in baffled flasks (500 ml). During exponential growth, 500 uM propionate was added to the cultures (H2O added to controls). Samples were harvested during mid-exponential growth. Four conditions, 12 samples total (triplicate). 5 ml of culture was harvested from each sample and added to an equal volume of RNAlater® RNA stabilization solution. Samples were then centrifuged at 4000 rpm for 15 min (4 °C) and the pellets were stored at – 80 °C. RNA was extracted using a RNAeasy Mini-Kit according to the manufacturers instructions. RNA was estimated with a NanoDrop ND-1000 spectrophotometer (NanoDrop technologies Inc, USA) and using agarose gel electrophoresis. Ribosomal RNA (rRNA) was then depleted from each sample (5 µg each) using the bacterial Ribo-Zero rRNA Removal Kit (Illumina). The integrity of the RNA was evaluated using an RNA 6000 Nano LabChip and an Agilent 2100 Bioanalyzer (Agilent Technologies, Germany). Eight indexed, strand-specific cDNA libraries were prepared, and samples were sequenced on an Illumina HiSeq 2000 with a 51-bp single-end read length (GATC Biotech, Germany).
