ABSTRACT: Expression data from yeast exposed to Caspofungin (wild type strain and rlm1, slt2, msn2/4 and bcy1 mutants) and Aminocandin (wild type strain)
Project description:We did transcription profiling on the effect of rlm1 (MAPK Slt2 transcription factor) deletion, slt2 (MAPK of Cell wall intregity pathway) deletion, bcy1 (Regulatory subunit of the cyclic AMP-dependent protein kinase (PKA)) deletion and msn2/4 (Stress-responsive transcriptional activators) deletion in genes involved in Caspofungin response (2 hours of treatment). In addition, we analyzed the genome-wide expression profile of the wild type strain in response to Aminocandin (2 hours of treatment).

Project description:hog1, slt2, rlm1, and msn2/4 mutants exposed to zymolyase
Project description:This SuperSeries is composed of the following subset Series: GSE9930: Wild type 3 hour exposure to zymolyase GSE9931: hog1 mutant 3 hour exposure to zymolyase GSE9932: slt2 mutant 3 hour exposure to zymolyase GSE9933: rlm1 mutant 3 hour exposure to zymolyase GSE9934: msn2/4 mutant 3 hour exposure to zymolyase S. cerevisiae wild type (BY4741) and mutants were grown on YEPD. For Zymolyase experiments, yeast cells were grown overnight at 24 °C to an optical density 0.8 - 1 (A600). The culture was refreshed to 0.2 O.D and grown at 24 °C for 2h 30min. Next, culture was divided into two parts. One continues growing under same conditions (non-treated culture) while the other was supplemented with 5units/ml Zymolyase 100T. Cells were collected at 3 hours of growth, frozen at -80 °C and processed for RNA extraction. The total RNA from one culture was analyzed, and, in addition, for this sample two different hybridizations were performed, including fluorochrome swapping in order to minimize transcriptional changes due to technical variability. This therefore corresponded to two DNA microarrays analyzed.
Project description:Samples GSM206658-GSM206693: Acquired Stress resistance in S. cerevisiae: NaCl primary and H2O2 secondary Transcriptional timecourses of yeast cells exposed to 0.7M NaCl alone, 0.5mM H2O2 alone, or 0.5mM H2O2 following 0.7M NaCl, all compared to an unstressed sample. Repeated using msn2∆ strain. Samples GSM291156-GSM291196: Transcriptional response to stress in strains lacking MSN2 and/or MSN4 Transcriptional timecourses of yeast cells (WT, msn2∆, msn4∆, or msn2∆msn4∆) exposed to 0.7M NaCl for 45 minutes or 30-37˚C Heat Shift for 15 min compared to an unstressed sample of the same strain.

Project description:Investigation of whole genome gene expression level changes in response to tunicamycin, an inhibitor of protein N-glycosylation, in Candida glabrata CBS138 delta-cnb1, delta-crz1, delta-slt2, and delta-ire1 mutants, compared to the wild-type strain. The mutations engineered into these strains render them hypersusceptible to tunicamycin. The mutants analyzed in this study are further described in Miyazaki, T. et al. (2010) Antimicrob Agents Chemother. 54(4):1639-1643 (PMID: 20100876) and Miyazaki, T. et al. (2010) FEMS Yeast Res 10(3):343-352, 2010 (PMID: 20214686).
Project description:The yeast PP2A-Cdc55 Serine/Threonine phosphatase regulates transcription under certain conditions. It is required for full activation of the environmental stress response mediated by the transcription factors Msn2 and Msn4. PP2A-Cdc55 contributes to sustained nuclear accumulation of Msn2 and Msn4 and extended chromatin recruitment under stress conditions such as hyperosmolarity stress. Transcript profiles of Msn2 and Msn4 double mutants are similar to cdc55 and the corresponding triple mutants. This argues for a Msn2/4 specific function of PP2A-Cdc55. Time course of 10 20 and 30 minutes hyperosmolarity treated yeast cells of wild type (W303), msn2msn4, cdc55, msn2msn5cdc55 genetic background.

A fifteen chip study using total RNA isolated from Candida glabrata wild-type control and four mutant strains, in which the entire ORFs of CNB1 (XP_448800), CRZ1 (XP_449644), SLT2 (XP_447735), or IRE1 (XP_446111) are deleted. Each chip measures the expression level of 5,217 genes from Candida glabrata CBS138 with six 60-mer-probe pairs per gene, with two-fold technical redundancy.
Project description:Candida parapsilosis wild type strain #12108 was exposed to 400ng/ml caspofungin. Randomly 30 adaptors were chosen. These adaptors as well as the parent were sequenced.
Project description:We did transcription profiling on the effect of rlm1 (MAPK Slt2 transcription factor) deletion and swi3 (component of SWI/SNF complex involved in chromatin remodeling) deletion in genes involved in cell wall stress (Congo Red) response.
