Genes with expression level regulated by genotype (N2 vs CB4856) and age at L3 larva and Late reproduction stage (96 hours at 24 centigrade). |
For model 2, authors used 100 permutations to estimate the FDR threshold. Per permutation, genotypes and ages were independently randomly distributed, keeping the among-gene structure intact. Then for each spot (23,232) on the array, model 2 was tested. The obtained P-values were used to estimate a threshold for each of the explanatory factors. Authors also used a genome-wide threshold of -log10 P-value = 2, which resembles an FDR of 0.072 and 0.060 for marker and the interaction age-marker for the developing worms and FDR of 0.050 and 0.065 for marker and age-marker for the aging worms. For the physiological age effect, authors used a log10 P-value = 8 in developing worms (0.012 FDR) and -log10 P-value = 6 (0.032 FDR). |

Genes from N2 animals with significantly increased expression after 72 hours of treatment on growth media with 10uM rapamycin in 2% DMSO. |
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. |

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. |

Expression Pattern Group E, enriched for genes involved in dephosphorylation. |
The significance (P 0.0001) of the relative age (time) was used to determine if a gene was differentially expressed between the three age (time) groups. The effect of this factor explaining gene expression differences was used to determine if the expression went up or down during the two age/time periods (t1 - t2 and t2 -t3). Authors used a permutation approach to determine the thresholds for the different mapping strategies. For each of the used models for eQTL mapping, authors used 23,000 permutations. For each permutation, authors randomly picked a spot; each spot could only be picked once. The gene expression and relative lifespan values were than randomly distributed over the RILs (and time points) and used for mapping. In this way, authors obtained a threshold for each of the explaining factors. For the single time points, authors used a FDR of 0.01 to adjust for multiple testing. The genome-wide threshold for this FDR is -log10 P = 3.8 for each of the three time points. For the combined models (t1 to t2 and t2 to t3), authors used a genome-wide threshold of -log10 P = 4, which resembles an FDR of 0.006, 0.001, and 0.006 for marker, age, and the interaction between marker and age, respectively. To determine the threshold for the single gene examples, authors used 1000 permutations as in the genome-wide threshold. The difference is that they use the gene under study in all of the permutations. The P-values for the gene specific thresholds were determined at FDR = 0.05. |

spermatogenesis-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 up regulated in aak-2 over expression line uthIs202[Paak-2c |
To identify genes that were significantly differentially expressed between each mutant and the control, linear modelling and empirical Bayes analysis was performed using the limma package. Limma computes an empirical Bayes adjustment for the t-test (moderated t-statistic), which is more robust than the standard two-sample t-test comparisons. To correct for multiple testing, Benjamin and Hochbergs method to control for false discovery rate was used. Genes with an adjusted P value of 0.05 or smaller and a fold-change in expression larger than twofold were considered differentially expressed. |
