Project description:Measure the relative changes of gene expression upon GIS2 overexpression; 100 ml of BY4741 cells bearing plasmid pBG1805-Gis2 (GIS2 under the control of the galactose promotor) or the empty plasmid pBG1805 (=control) were grown in synthetic medium lacking uracil (SC-Ura supplemented with 2% raffinose) at 30 degrees to an OD600 of 0.45- 0.5. Expression of GIS2 was induced with 2% galactose for 1.5 h and cells were harvested by centrifugation, washed twice with 800 ul of ice-cold sterile water. 100 ul (1/8) of cells were removed and RNA was isolated by hot phenol extraction for microarray analysis. 6.7 ug of total RNA derived from cells expressing the empty vector (pBG1805) or Gis2p (pBG1805-Gis) were reverse transcribed in the presence of 5-(3-aminoallyl)-dUTP and natural dNTPs with a mixture of N9 and dT20V primers, and cDNAs were covalently linked to Cy3 and Cy5 NHS-monoesters (GE HealthSciences Cat# RPN5661), respectively, and competitively hybridized on yeast oligo arrays at 42 degrees celsius for 14 hours in formamide-based hybridization buffer. Microarrays were scanned with an Axonscanner 4200 (Molecular Devices) and analyzed with GenePix Pro 5.1 (Molecular devices). Biological Replicate

Project description:Measure the relative changes of gene expression upon GIS2 overexpression; BY4741 cells bearing plasmid pBG1805-Slf1 or control plasmid pBG1805 were grown in SC ura- gal at 30 C for 6 or 24 hours. An overnight culture of cells was inoculated at an OD600 of 0.1 and further grown to an OD600 of 0.5- 0.7 in 60 ml SC Ura- Gal at 30 C. Cells were harvested by centrifugation, washed twice with 600 ul of ice-cold sterile water. 200 ul of cells were removed and RNA was isolated by hot phenol extraction for microarray analysis. 7.5 ug of total RNA derived from cells expressing the empty vector (pBG1805) or Slf1p (pBG1805_Slf1) were reverse transcribed in the presence of 5-(3-aminoallyl)-dUTP and natural dNTPs with a mixture of N9 and dT20V primers, and cDNAs were covalently linked to Cy3 and Cy5 NHS-monoesters (GE HealthSciences Cat# RPN5661), respectively, and competitively hybridized on yeast oligo arrays at 42 degrees celsius for 14 hours in formamide-based hybridization buffer.

Project description:To compare total RNA levels in miR-124 and mock-transfected cells (Figure S3), 5-10 ug of total RNA from miR-124-transfected cells or mock-transfected cells or universal reference RNA (Stratagene Cat# 740000) was reverse transcribed with Superscript III (Invitrogen Cat# 18080085) in the presence of aminoallul-dUTP 5-(3-aminoallyl)-dUTP (Ambion Cat# AM8439) and natural dNTPs (GE Healthsciences Cat# US77212) with 10 ug of N9 primer (Invitrogen). Subsequently, amino-allyl-containing cDNAs from miR-124 and mock-transfected cells were covalently linked to Cy5 NHS-monoesters, and universal reference cDNA was covalently linked to Cy3 NHS-monoesters (GE HealthSciences Cat# RPN5661). Cy5- and Cy3-labeled cDNAs were mixed and diluted into 50 ul of solution containing 3x SSC, 25 mM Hepes-NaOH (pH 7.0), 20 ug human Cot-1 DNA (Invitrogen Cat# 15279011), 20 ug of poly(A) RNA (Sigma Cat# P9403), 25 ug of yeast tRNA (Invitrogen Cat# 15401029), and 0.3% SDS. The sample was incubated at 95 C for 2 min, spun at 14,000 rpm for 10 mins in a microcentrifuge, then hybridized at 65 C

Project description:MicroPoly(A)Pure kits (Ambion) were used to prepare mRNA from P. salmonis-infected and control Atlantic salmon head kidney. Head kidney mRNA samples were prepared from pooled (n = 10) infected or control kidney. Approximately 200 ng of infected or control head kidney mRNA was used as template in aRNA synthesis reactions. Two infected head kidney samples were pooled to yield 8.9 ug of aRNA, and a single control head kidney sample contained 8.4 ug of aRNA. Infected and control head kidney aRNA samples were visualized on agarose gels to check quality and quantity (data not shown). Except for the amounts of aRNA and reverse transcription (RT) primer used, head kidney target labeling reactions and microarray hybridizations were identical. Head kidney target syntheses used 2 ug of aRNA and 2 ug of random primers (Roche). RT primers were mixed with aRNA samples, and nuclease-free H2O (Invitrogen) was added to make 10 ul total volume. Samples were incubated at 70 degrees C for 4 min, then placed on ice. RT reactions included 50 mM Tris HCl pH 8.3, 75 mM KCl, 3 mM MgCl2, 10 mM DTT, 0.5 mM each dATP, dCTP, and dGTP, 0.2 mM dTTP, 0.05 mM Cy3-dUTP or Cy5-dUTP (Amersham), 40U RNAguard ribonuclease inhibitor (Amersham), and 400U Superscript II Rnase H- reverse transcriptase (Invitrogen). RT reactions were incubated at 42 degrees C for 2.5 h, followed by addition of 0.025U RNase A (Sigma) and 1.5U RNase H (New England BioLabs) and incubation at 37 degrees C for 30 min. Labeled targets were cleaned using the Qiaquick PCR purification kit (Qiagen) and precipitated, with 300 mM sodium acetate, 1 ul of 20 ug/ul glycogen (Invitrogen), and 2.5 volumes of 100% ethanol, at -20 degrees C overnight. Each labeled target was recovered by centrifugation (14,000 rpm, 4 degrees C, 1 h), washed in 70% ethanol, air-dried, and resuspended in 60 ul of hybridization buffer: 50% deionized formamide, 5X SSC, 0.1% SDS, 5 ul of 5 ug/ul oligo dT (5’T18[Q-N]3’), 5 ul of 2 ug/ul BSA (Pierce), and 2 ul of 10 ug/ul sonicated human placental DNA (Sigma). Targets were incubated at 96 degrees C for 3 min, and then at 65 degrees C until applied to microarrays. Microarrays were prepared for hybridization by washing 2 X 5 min in 0.1% SDS, washing 5 X 1 min in MilliQ H2O, immersing 3 min in 95 degrees C MilliQ H2O, and drying by centrifugation (2000 rpm, 5 min, in 50 ml conical tube). Microarray hybridizations were run in the dark under HybriSlips hybridization covers (Grace Biolabs) in slide hybridization chambers (Corning) submerged in a 45 degrees C water bath for 16 h. Coverslips were floated off in 45 degrees C (1X SSC, 0.2% SDS), and arrays were washed 1 X 10 min in 45 degrees C (1X SSC, 0.2% SDS), 3 X 4 min in room temperature (0.1X SSC, 0.1% SDS), and 4 X 4 min in room temperature 0.1X SSC. Slides were dried by centrifugation as before. Fluorescent images of hybridized arrays were acquired immediately at 10 um resolution using ScanArray Express (PerkinElmer). The Cy3 and Cy5 cyanine fluors were excited at 543 nm and 633 nm respectively, and the same laser power (90%) and photomultiplier tube (PMT) settings were used for all slides in a study (PMT 75 Cy3, PMT 63 or 64 Cy5 for head kidney study). Fluorescent intensity data were extracted from TIF images using Imagene 5.5 software (Biodiscovery). Keywords: other
