Project description: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:Data processing included: 1. Filtering of those bad quality image spots (these includes alterations on the shape or hybridization) 2. Filtering of low intensity which was done flagging with -50 those spots whose feature intensity was lower in any of both channels than the average of the local background in the corresponding channel for all spots. However, those genes whose feature intensity in one channel was under the limit but in the other channel was 5 times over limit were considered as on-off genes and were not filtered. 3. Filtering of low reproducibility intrachip replicated spots. Normal distribution was created with the value obtained from the formula: log2(Rax1/Rb) which means logarithm (two-based) of one ratio multiplied by the inverse of its replicate. This value for each gene shoud keep between the range of average ± 3SD. Those genes out of these range are flagged as -25 4. Normalization of ratios was done by Lowess mathematical method. Correction factor was 0.33 This SuperSeries is composed of the following subset Series: GSE960: wild type 0 hours exposure to congo red GSE961: wild type 2 hours exposure to congo red GSE962: wild type 4 hours exposure to congo red GSE963: wild type 6 hours exposure to congo red GSE964: slt2 mutant 4 hours exposure to congo red GSE965: rlm1 mutant 4 hours exposure to congo red GSE966: wild type two hours exposure to zymolyase Keywords: SuperSeries Refer to individual Series
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.
