Reduced humidity (98% relative humidity). |
Genes that were down-regulated after one day exposure to reduced humidity (98% relative humidity) according to microarray analysis. |
Multiple hypothesis testing with the Benjamini-Hochberg correction was applied on calculated p-values. A change in the expression level was considered to be significant if the adjusted p-value was less than 0.001. |

Genes that showed expression levels higher than the corresponding reference sample (embryonic 24hr reference). |
A Mann-Whitney U test with an empirical background model and FDR correction for multiple testing was used to detect expressed transcripts (Benjamini and Hochberg 1995). Genes and TARs with an FDR <= 0.05 were reported as expressed above background. Authors detected differentially expressed transcripts using a method based on linear models. Genes and TARs were called differentially expressed if the FDR was <= 0.05 and the fold change (FC) >= 2.0. To more strictly correct for potential false-positives resulting from multiple sample comparisons, authors divided individual FDR estimates by the number of samplesor sample comparisons, respectively. This resulted in an adjusted FDR of 1.3 * 0.0001 for expression above background and of 7.4 * 0.0001 for differential expression. Authors called genes selectively enriched in a given tissue if they met the following requirements: (1) enriched expression in a given tissue (FDR <= 0.05 and FC >= 2.0), (2) fold change versus reference among the upper 40% of the positive FC range observed for this gene across all tissues, and (3) fold-change entropy among the lower 40% of the distribution observed for all genes. |

male soma-enriched |
Comparisons were made between genotypes by subtracting the mean log value of one ratio from another, and the significance of the difference was evaluated using Student t-test for two populations. For the fem-3(gf) versus fem-1(lf) direct comparison, authors performed the same analysis, except they used a Students t-test for one population. Author chose a combination of a twofold difference with a t value exceeding 99% confidence (P < 0.01), because these criteria allowed the inclusion of essentially all genes that had previously been identified as germline-enriched in a wt/glp-4 hermaphrodite comparison. Additionally, requiring a twofold difference reduced false positives, as the number of genes with two-fold difference and a P<0.01 only included ~100 genes more than with P < 0.001, and almost all genes showed germline expression by in situ hybridization. |

control(maintained under normal lab light (mostly dark, in incubators).) vs UVC-EtBr-exposed(exposed to 7.5 J/m2 UVC radiation 3 times, 24 h apart (48 h total) and exposed to EtBr (5ug/mL in agar).) at 3 h after the third UVC dose (51h), which is also 3 h after being placed on food. |
Genes differentially expressed in control vs after UVC exposure and EtBr treatment at the 3h timepoint (3 h after the third UVC dose (51h), which is also 3 h after being placed on food). |
Transcripts were defined as fold-change >1.2, p < 0.05 based on Rosetta Resolver analysis for all pairwise treatment comparisons. The fold-change refers to the second intensity over the first. |

Genes that showed increased expression in bar-1(ga80) animal comparing to in N2. |
All statistical analyses were performed using the statistical programming language R (version 2.13.1 x 64). A linear model was used to determine the effect and significance of the genotype on the expression levels (probe intensity + genotype + error). Using permutations of the original data in the same linear model, authors determined thresholds adjusted for multiple testing (FDR 0.05: -log10(p) > 2; FDR 0.01: -log10(p) > 3). To correct for the developmental difference between bar-1(ga80) and N2 authors used the developmental gene expression data from Snoek et al. (2014) together with the gene expression data generated for this study (bar-1(ga80) vs. N2) in one linear model (probe intensity, sample age + genotype + error). The intensities were corrected for batch effect and for sample age authors used an age of 44 hours for the bar-1(ga80) samples (as estimated), and 48 hours for the N2 samples. |

Genes that showed flat mRNA expression level throughout the 16 hour time courses from L3 larva to young adult. |
The following three lines of R code were used to perform the classification: increasing <-2*amplitude-PC1 < -1.7; oscillating <-!increasing & (amplitude > 0.55); flat <-!increasing & !oscillating; Note that the amplitude of a sinusoidal wave corresponds to only half the fold change between trough and peak. |

After array normalization, significance analysis of microarray was performed on data from individual time points (two class unpaired response) to identify genes with small but consistent changes. A false-discovery rate (FDR) of ~1% was used as criteria to consider a gene differentially regulated.Authors chose this particular FDR because it was the lowest FDR that did not significantly reduce the number of estimated true positives. |

Coexpression clique No. 270, ZC373.2-Y62H9A.6_1596, 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. |
