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).

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:We have performed a genome wide expression profile study of the essential transcriptional co-repressor protein Ssn6 in Schizosaccharomyces pombe. Ssn6 affected targets were identified by over expression of Ssn6 protein in a WT strain. A WT strain holding a plasmid expressing Ssn6 (pDUAL-Ssn6) was compared against the expression in a WT with the empty plasmid (pDUAL-EMPTY) strain. Keywords: Overexpression/WT

Project description:We performed a genome-wide screen for genetic MDM33 interaction partners. Using the opposite approach of the well known synthetic dosage lethality (screening for deletion strains in which a non-toxic overexpression is associated with a synthetic growth arrest) we screened the whole genome for genes that are essential for the growth arrest associated with MDM33 overexpression. In a pooled collection of viable haploid gene deletion mutants, of which each is tagged with a unique identifying molecular â??â??bar-codeâ??â?? sequence, the overexpression of MDM33 was induced using a galactose responsive promotor. While overexpression resulted in a growth arrest in almost all strains a small fraction of deletion mutants was able to grow under inductive conditions. We identified these strains using a microarray DNA hybridization technique that quantifies the abundance of the molecular barcodes. We propose that the affected genes are possible functional genetic interaction partners of MDM33. Replicate set 1: knockout strains transformed with empty vector and MDM33 overexpression vector; each transformation plated on glucose and galactose media; uptags and downtags were labelled and detected independently; Replicate set 2: same as replicate set 1, plus dye-swap;
