  Genes with expression level regulated by genotype (N2 vs CB4856) 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). WBPaper00040858:eQTL_regulated_developing
  Transcripts detected in germline isolated from day-1 adult hermaphrodite animals. All three experiments have CPM >= 1. WBPaper00067147:germline_expressed
  Significantly differentially expressed genes as determined by microarray analysis of wild-type and cde-1 mutant germlines. RNAs that changed at least 2-fold with a probability of p < 0.05 were considered differentially regulated between wildtype and cde-1. WBPaper00035269:cde-1_regulated
  Transcripts that showed significantly altered expression after 24 hour exposure to stavudine (d4T) starting at L1 lava stage. DESeq WBPaper00053302:stavudine_24h_regulated
  Genes down regulated by mir-243(n4759). RNAs that changed at least 2-fold with a probability of p > 0.05 in three biological replicates were considered differentially regulated between wild-type and mir-243. WBPaper00036130:mir-243_down_regulated
  Transcripts that showed significantly increased expression in 10-days post L4 adult hermaphrodite N2 grown at 20C, comparing to in 1-day post L4 adult hermaphrodite N2 animals grown at 20C. CuffDiff, fold change > 2. WBPaper00065096:Day10_vs_Day1_upregulated
  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. [cgc5767]:expression_class_M

  Genes with increased RNA expression after 24 hours rotenone treatment EdgeR provides 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 Hochbergs approach for controlling the false discovery rate (FDR). Transcripts with an adjusted p-value smaller 0.05 were assigned as differentially expressed. WBPaper00044426:rotenone_24h_upregulated
Temprature shift to 28C for 24 hours. Transcripts that showed significantly decreased expression after animals were exposed to 28C temperature for 24 hours. Differentially expressed genes wereidentified using DESeq (v.1.18.0) by normalizing readsbased on the negative binomial distribution method andcomparing each HS timepoint to the 0-h control.

  Genes that were not enriched in either spermatogenic fem-3(q96gf) nor oogenic fog-2(q71) gonads, according to RNAseq analysis. To identify differentially expressed transcripts, authors used R/Bioconductor package DESeq. WBPaper00045521:Gender_Neutral

  TGF- Dauer pathway adult transcriptional targets. Results obtained by comparing the microarray results of the dauer-constitutive mutants daf-7(e1372), daf-7(m62), and daf-1(m40) with dauer-defective mutants daf-3(mgDf90), daf-5(e1386), and daf-7(e1372);daf-3(mgDf90) double mutants at the permissive temperature, 20C, on the first day of adulthood. SAM WBPaper00031040:TGF-beta_adult_downregulated
  Transcripts down regulated in hpl-2(tm1489) embryo comparing to N2 in tiling array analysis. Oligos from the tiling array were mapped to chromosome coordinates of the exons from Wormbase WS180. Any oligo that mapped to a gene on both the Watson and Crick strands was excluded. The remaining oligos were then grouped together (perfect match and mismatch) into probe sets and written out into an Affymetrix CDF file. The CDF file was converted into an R-package and loaded into R. The expression values were calculated using the justRMA function from Bioconductor. This used a Benjamini and Hochberg false discovery rate correction. WBPaper00040560:hpl-2_embryo_downregulated
  Genes expressed in N2. Expressed transcripts were identified on the basis of a Present call in 3 out of 4 N2 experiments as determined by Affymetrix MAS 5.0. WBPaper00025141:N2_Expressed_Genes
  Embryonic class (E): genes that significantly increase in abundance at some point during embryogenesis. 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. [cgc5767]:expression_class_E
  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.
