Genes with significantly increased expression in eat-2(ad465) treated with 2% DMSO for 72 hours, comparing to in N2 treated with 2% DMSO for 72 hours. |
Analysis of gene expression data was carried out with the Affymetrix Transcriptome Analysis Console. Data preprocessing (using RMA normalization) and QC metrics were performed using Affymetrix Expression Console TM and manually inspected afterwards. Expression analysis was carried out for each two pairwise conditions. FDR statistical correction for multiple testing resulted in a slightly lower number of DEGs in most cases. P-value < 0.05 and fold change > 2.0 were used to determine differentially expressed genes. |

Down-regulated genes (fold change > 1.5) in two CoQ-deficient clk-1 mutant strains (e2519, qm30) compared to wild types N2. |
Fold-changes of intensities were calculated from the arithmetic mean of gene expression values between experimental and corresponding control group. Fold change >= 1.5 was used as cut-off. |

Coexpression clique No. 211, srj-42-srw-113, on the genome-wide coexpression clique map for the nematode GPL200 platform. |
All available microarray datasets for the GPL200 platform (Affymetrix C. elegans Genome Array) were obtained from the GEO repository. This included 2243 individual microarray experiments. These were normalized against each other with the software RMAexpress (Bolstad, 2014). Based on these normalized values, Pearsons correlation coefficients were obtained for each probe-probe pair of the 22,620 probes represented on this array type. The resulting list of correlation coefficients was then ranked to generate the ranked coexpression database with information on each probe represented on the GPL200 platform. |

Fungi infection: Candida albicans, heat-killed C. albicans versus heat-killed E. coli. |
Differentially expressed genes in the following exposure comparison :heat-killed C. albicans versus heat-killed E. coli. |
Data were analyzed using Resolver Gene Expression Data Analysis System, version 5.1 (Rosetta Inpharmatics). Three biologic replicates per condition were normalized using the Resolver intensity error model for single color chips. Conditions were compared using Resolver to determine the fold change between conditions for each probe set and to generate a P value using a modified t-test. Probe sets were considered differentially expressed if the fold change was 2-fold or greater (P < 0.01). When comparing datasets, the overlap expected by chance alone was determined in 50 groups of randomly selected C. elegans genes using Regulatory Sequence Analysis Tools (http://rsat.ulb.ac.be/rsat/), a technique that has been used for similar analyses. P values were determined using chi-square tests. |
