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). |

Genes that showed significantly decreased expression in daf-19(m86);daf-12(sa204) comparing to in daf-12(sa204), at L1 larva stage. |
BRB Array Tools were used to identify genes with statistically significant variation in expression. The probability threshold was set at a maximum of 0.05 (p-value <= 0.05) for genes to be considered statistically differentially expressed in wild-type and mutant populations. Genes with a signal variation of 1.5-fold or greater were selected for subsequent experiments. To reduce false discoveries, a class comparison test was conducted using a multivariate per mutation test with a confidence level of 97% (L1 analysis) and 90% (adults). |

Genes enriched in intestine. |
To identify genes that are significantly enriched by mRNA tagging, we first normalized the total amount of Cy3 and Cy5 signal to each other in each hybridization. We measured the ratio of the signals from the co-immunoprecipitated mRNA (Cy5) to total RNA in the cell extract (Cy3), and calculated the percentile rank for each gene relative to all genes in each hybridization. The mean percentile rank was determined from eight repeats of the mRNA-tagging experiment. Student's t-test was used to determine which genes showed a mean enrichment significantly greater than the median enrichment for all genes (P<0.001). |

Genes up-regulated following nhr-25(RNAi). |
Pair-wise significance testing (mutant/RNAi vs. wild-type/vector) was performed using the Bioconductor package limma and p-values were initially corrected for multiple testing using the false discovery rate (FDR) method of Benjamini and Hochberg. Authors defined differential expression as log2(ratio) >= 0.848 with the FDR set to 5%, and p-value <= 0.001. |

Expression Pattern Group H, enriched for genes involved in embryonic development. These patterns have in common that they all have genes of which the expression goes up after the juvenile stage. The expression of the genes in these patterns remains high or even goes up after reproduction. |
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. |
