Title |
rapamycine H2O vs rapamycine NH4 replicate 2 |
Sample type |
RNA |
|
|
Channel 1 |
Source name |
Total RNA of S288C strain
|
Organism |
Saccharomyces cerevisiae S288C |
Characteristics |
addition at t0: H2O biological rep: 2
|
Growth protocol |
An overnight cell pre-culture of S288c yeast strain was firstly obtained on a YEPD medium, before to transfer cells in an YNB medium for 32h. A constant population of cells was then nitrogen starved for 16h in an YNB-N medium in order to reach the stationary phase. Ammonium chloride (20 mM) or water (control) was then added to the medium after supplementation with rapamycin.
|
Extracted molecule |
total RNA |
Extraction protocol |
After 30 minNH4 or H2O addition, sampling was performed in less than 1 min as followed: cells were filtrated under vacuum on a 0.45 µm HA membrane, collected and suspended in 1.5 ml DEPC water then stored at -80°C before RNA extraction. RNA were extracted from yeast cell culture as described previously (Chomczynski and Sacchi, 1987). The RNA concentrations were determined by measuring absorbance at 260 nm with a Nanodrop apparatus.
|
Label |
cy3
|
Label protocol |
Retrotranscription and labeling were performed using a ChipShot direct labeling and clean-up system kit (Promega) according to manufacturer’s indications.

|
Hybridization protocol |
Microarray hybridizations were performed using a Pronto Universal Microarray kit (Corning) according to manufacturer’s indications. Two biological replicates were done based on a dye swap design (S288C strain, 2 biological replicates with ammonium chloride addition and 2 biological replicates with water addition (control)).
|
Scan protocol |
Microarrays were scanned using a GenePix pro 3 scanner (Axon Instruments).
|
Description |
Biological replicate 2 of 2 of rapamycine and NH4 addition vs. Biological replicate 2 of 2 of rapamycine and H2O addition. Swap 2
|
Data processing |
Data were processed using the R software (R2.9.2) and the Limma package (R Development Core Team 2010; Smyth 2005, Smyth et al. 2005; Smyth and Speed 2003). Within and between array normalizations were performed respectively by the print-tip-loess and quantile methods. Differentially expressed genes were identified through a linear model approach and a Benjamini-Hochberg method was used to adjust the p-values (Benjamini and Hochberg, 1995).
