  Transcripts of coding genes that showed significantly decreased expression in muscle. DESeq2 (version 1.24.0). Transcripts with a false-discovery rate adjusted p-value less than 0.05 were considered significantly differentially expressed. WBPaper00062325:muscle_depleted_coding-RNA
adult vs dauer larva Transcripts that showed differential expression in adult vs dauer lava in N2 animals at 20C. N.A. WBPaper00050488:adult_vs_dauer_regulated_N2_20C
  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.

Osmotic stress Transcripts that showed significantly altered expression with 500 mM salt (NaCl) vs 100 mM salt when no food was present DESeq(version 1.10.1), FDR < 0.05. WBPaper00050726:OsmoticStress_regulated_NoFood

For log2 fold changes > 0.00001 the values > 81.25th percentile were defined as up-regulated and for log2 fold changes < -0.00001 the values < 18.75th percentile were defined as down-regulated.

  Genes up regulated in alg-1(gk214) comparing to in N2. Differential expression was assessed using an empirical Bayes statistics using the eBayes function. WBPaper00040823:alg-1(gk214)_upregulated
  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). WBPaper00040858:eQTL_age_regulated_aging
