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. |

Up-regulated genes under 0.5mg/l CPF treatment at 16 centigrade. |
The Rank Product package was used to identify the differentially expressed genes between controls and treatment in each experiment. Briefly, genes were ranked based on up- or downregulation by the treatment in each experiment. Then, for each gene a combined probability was calculated as a rank product (RP). The RP values were used to rank the genes based on how likely it was to observe them by chance at that particular position on the list of differentially expressed genes. The RP can be interpreted as a p-value. To determine significance levels, the RP method uses a permutation-based estimation procedure to transform the p-value into an e-value that addresses the multiple testing problem derived from testing many genes simultaneously. Genes with a percentage of false-positives (PFP) < 0.05 were considered differentially expressed between treatments and control in each experiment. This method has the advantage to identify genes with a response to the toxicants even when the absolute effect of the response was low. Because authors used sub-lethal concentrations of the toxicants, methods that use thresholds based on absolute fold change would not identify small changes in gene expression. Moreover, RP has proved to be a robust method for comparing microarray data from different sources and experiments. |

Genes that showed increased expression after exposure to 7.5uM CH3HgCl for 24 hours. |
Rosetta Resolver was used to identify differentially expressed genes using an error-weighted, 1-way ANOVA with a Bonferroni correction. A 2-fold change in expression, relative to untreated controls, and a p-value < 0.01 was required for a gene to qualify as significantly, differentially expressed. |

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. |

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 with differential expression under 0.5mg/l Chlorpyrifos (CPF) and 0.5mg/l Diazinon (DZN) treatment at 24 centigrade. |
To identify the differentially expressed genes in each treatment authors used linear models per toxicant and temperature (gene expression = Toxicant (effect) + error). The lm function in R stats package was used to implement the linear models analysis with recommended default options. For threshold determination authors used a permutation approach. For each of the 23,232 permutations used authors randomly picked a transcript (array spot), which could only be picked once. Authors combined all the expression values of this transcript and randomly distributed them over the replicates and used them in the linear model. In this way authors obtained a threshold for each of the toxicants. Authors used a -log10 p-value 2 as common threshold for the analysis, which resembles to the following FDR per toxicant: 0.0155 for CPF at 24 centigrade, 0.0148 for DZN at 24 centigrade, 0.0168 for CPF+DZN at 24 centigrade, 0.0142 for CPF at 16 centigrade, 0.0151 for DZN at 16 centigrade, and 0.0148 for CPF+DZN, at 16 centigrade. |
