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. |

Genes that were downregulated in lin-15B(n744). |
For each gene in each microarray hybridization experiment, the ratio of RNA levels from the two samples was transformed into a log2 value and the mean log2 ratio was calculated. The log2 ratios were normalized by print-tip Loess normalization (Dudoit and Yang, 2002). All genes with a false discovery rate of <= 5% (q <= 0.05) (Storey and Tibshirani, 2003) and a mean fold-change ratio of >= 1.5 were selected for further analysis. |

Maternal class (M): genes that are called present in at least one of the three PC6 replicates. |
A modified Welch F statistic was used for ANOVA. For each gene, regressed error estimates were substituted for observed error estimates. The substitution is justified by the lack of consistency among the most and least variable genes at each time point. Regressed error estimates were abundance-dependent pooled error estimates that represented a median error estimate from a window of genes of similar abundance to the gene of interest. A randomization test was used to compute the probability Pg of the observed F statistic for gene g under the null hypothesis that developmental time had no effect on expression. P-values were not corrected for multiple testing. |

mRNAs that showed increased expression in P-granule RNAi animales (simultaneously targeting pgl-1, pgl-3, glh-1 and glh-4) comparing to in control RNAi animals. Set 1 transcripts were defined as P-value < 0.05 and fold change > 2. |
DESeq was used. Fold change between the average of the four control replicates and the average of the four test replicates was used to calculate the significance using a negative binomial distribution. An adjusted P-value was calculated using the Benjamini-Hochberg method for multiple testing correction. |

Expression Pattern Group C, enriched for genes involved in metabolic processes. |
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. |

Genes that showed increased expression after nicotic acid (NA) treatment. |
Raw counts for the genes were analyzed using the R Statistical Computing Environment and the Bioconductor packages DESeq and edgeR. Both packages provide statistical routines for determining differential expression in digital gene expression data using a model based on the negative binomial distribution. The resulting p-values were adjusted using the Benjamini and Hochberg's approach for controlling the false discovery rate (FDR). If both FDR values (by DESeq and edgeR) were smaller than p = 0.05, genes were assigned as differentially expressed. |
