Genes with expression level regulated by genotype (N2 vs CB4856) and age at old adults stage (214 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). |

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 with expression level regulated by genotype (N2 vs CB4856) at Old adults stage (214 hours at 24 centigrade). |
Authors permuted transcript values and used a genome-wide threshold of log10 P-value = 2, which resembles a false discovery rate (FDR) of 0.0136. |

Genes from eat-2(ad465) 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 differentially expressed under UVC exposure and EtBr treatment vs under EtBr treatment but without UVC exposure at the -1h timepoint (just prior to the third UVC dose (48h)). |
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 with differential expression under 0.5mg/l Chlorpyrifos (CPF) 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. |
