  Transcripts expressed in intestine, according to PAT-Seq analysis using Pges-1-GFP-3XFLAG mRNA tagging. Cufflinks FPKM value >=1. WBPaper00050990:intestine_expressed
  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
  Transcripts that showed significantly decreased expression in day 3 adult hermaphrodite comparing to in L4 larva daf-16(mu86);glp-1(e2141) animals. Fold change > 2, FDR < 0.05 WBPaper00064088:Day-3-adult_vs_L4_downregulated_daf-16(mu86);glp-1(e2141)
  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

  Transcripts that showed significantly increased expression in xrep-4(lax137). DESeq2. Genes were selected if their p value < 0.01. WBPaper00066062:xrep-4(lax137)_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. WBPaper00061341:28C_24h_downregulated
  Genes that showed expression levels higher than the corresponding reference sample (L2 all cell 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 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
Bacteria infection: Enterococcus faecalis OG1RF. Exposure for 16 hours. Transcripts that showed significantly decreased expression in hpx-2(dg047) after animals were exposed to E. faecalis OG1RF for 16 hours comparing to exposure to E. Coli OP50. Cuffcompare and Cuffdiff WBPaper00056090:E.faecalis_downregulated_hpx-2(dg047)
  Genes found to be regulated by low-copy overexpression of sir-2.1 with p < 0.014. N.A. WBPaper00026929:sir-2.1_overexpression_regulated
  Germline-intrinsic transcripts. Comparisons were made between genotypes by subtracting the mean log value of one ratio from another, and the significance of the difference was evaluated using Student t-test for two populations. For the fem-3(gf) versus fem-1(lf) direct comparison, authors performed the same analysis, except they used a Students t-test for one population. Author chose a combination of a twofold difference with a t value exceeding 99% confidence (P < 0.01), because these criteria allowed the inclusion of essentially all genes that had previously been identified as germline-enriched in a wt/glp-4 hermaphrodite comparison. Additionally, requiring a twofold difference reduced false positives, as the number of genes with two-fold difference and a P<0.01 only included ~100 genes more than with P < 0.001, and almost all genes showed germline expression by in situ hybridization.

  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.

  Transcripts unqiuely expressed in intestine, according to PAT-Seq analysis using Pges-1-GFP-3XFLAG mRNA tagging. Cufflinks FPKM value >=1. WBPaper00050990:intestine_enriched
  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

    Expr10500 Inferred Expression. EPIC dataset. http://epic.gs.washington.edu/ Large-scale cellular resolution compendium of gene expression dynamics throughout development. This reporter was inferred to be expressing in this cell or one of its embryonic progenitor cells as described below. To generate a compact description of which cells express a particular reporter irrespective of time, the authors defined a metric "peak expression" for each of the 671 terminal ("leaf") cells born during embryogenesis. For each of these cells, the peak expression is the maximal reporter intensity observed in that cell or any of its ancestors; this has the effect of transposing earlier expression forward in time to the terminal set of cells. This metric allows straightforward comparisons of genes' cellular and lineal expression overlap, even when the expression occurs with different timing and despite differences in the precise time point that curation ended in different movies, at the cost of ignoring the temporal dynamics of expression, a topic that requires separate treatment. For simplicity, the authors use the term "expressing cells" to mean the number of leaf cells (of 671) with peak expression greater than background (2000 intensity units) and at least 10% of the maximum expression in that embryo.
