Sample GSM618313 Query DataSets for GSM618313
Status Public on Oct 20, 2011
Title BL23 bile_2
Sample type RNA
 
Source name Cultured cells
Organism Lacticaseibacillus casei
Characteristics agent: bile
strain: BL23
Treatment protocol Cells were grown in MRS medium at 37C without shaking until O.D. 595 nm. reached 0.5. The culture was then two fold diluted with prewarmed MRS medium supplemented with 0.2% bovine bile (Sigma) and incubation continued for 45 min.
Growth protocol Cells were stored at -80C in MRS medium supplemented with 15% glycerol (stock culture). For the assay, cells from the stock culture were inoculated in MRS agar plates. A single colony was used to inoculate 5 ml of MRS medium and the culture was incubated overnight at 37C. This culture was used to inoculate MRS medium at 0.05 O.D. 595 nm. for the treatment or control assays.
Extracted molecule total RNA
Extraction protocol Total RNA was isolated from L. casei by using TRIZOL reagent (Invitrogen). Cells were collected by centrifugation, washed with cold 50 mM EDTA (pH 8.0), resuspended in 1 ml of TRIZOL reagent, and then mechanically disrupted with glass beads in a cell disrupter (Savant Instruments, Holbrook, N.Y.). Additional steps were performed according to the instructions of the TRIZOL manufacturer. RNA samples purified as described above were treated with the Ambion Turbo DNA-free kit (Applied Biosystems) using the routine DNase I treatment outlined by the supplier in order to remove contaminating DNA. The quality and concentration of the RNA samples were subsequently evaluated by using the Experion automated electrophoresis system (Bio-Rad). Samples with 23S/16S ratios lower than 0.85 were discarded.
Label 33P-dCTP
Label protocol First-strand cDNA was synthesized from 45 µg RNA using the Transcriptor first strand cdna synthesis kit (Roche) with random hexamer primers as recommended by the manufacturer. Labelled cDNA was purified with illustra MicroSpin G-50 Columns (GE Healthcare) as recommended by the manufacturer.
 
Hybridization protocol SDS based hybridization solution, during 24 hours
Scan protocol FUJIFILM FLA-3000
Data processing The software for image analysis is ArrayVision 7.0 (Imaging Research Inc.). This software yields raw and background substracted data.
The Background Substracted Signals are raw individual data. After considering the three replicates performed in the experiment and after median normalization, first between replicates and after between conditions, we obtain the ratio values for each gene/ORF (see supplementary file on Series record).
