Regulated By Treatment Description Algorithm Primary Identifier
  Transcripts expressed in neuronal cells, by analyzingfluorescence-activated cell sorted (FACS) neurons. DESeq. False discovry rate (FDR) < 0.1. WBPaper00048988:neuron_expressed
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
  Transcripts that showed significantly higher expression in somatic gonad precursor cells (SGP) vs. head mesodermal cells (hmc). DESeq2, fold change >= 2, FDR <= 0.01. WBPaper00056826:SGP_biased
  Proteins interacting with NHR-49-GFP according to co-IP and LC-MS. N.A. WBPaper00064071:NHR-49_interacting
  Genes with expression level regulated by genotype (N2 vs CB4856) at Late reproduction stage (96 hours at 24 centigrade). Authors permuted transcript values and used a genome-wide threshold of log10 P-value = 2, which resembles a false discovery rate (FDR) of 0.0118. WBPaper00040858:eQTL_regulated_reproductive
  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
Bacteria infection: Staphylococcus aureus MW2. 4 hours of exposure. Transcripts that showed significantly increased expression after N2 animals had 4 hours of infection by Staphylococcus aureus (MW2). DEseq 1.18.0, adjusted p-value < 0.05. WBPaper00056471:S.aureus-4h_upregulated_N2
  Strictly maternal class (SM): genes that are the subset of maternal genes that are not also classified as embryonic. 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_SM
  Transcripts that showed significantly altered expression after 24 hour exposure to stavudine (d4T) starting at L1 lava stage. DESeq WBPaper00053302:stavudine_24h_regulated
  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.

  Transcripts that showed significantly increased expression in isp-1(qm150) comparing to in N2. Differential gene expression analysis was performed using the quasi-likeli-hood framework in edgeR package v. 3.20.1 in R v. 3.4.1. WBPaper00053810:isp-1(qm150)_upregulated

UVC-EtBr-exposed(exposed to 7.5 J/m2 UVC radiation 3 times, 24 h apart (48 h total) and exposed to EtBr (5ug/mL in agar).) vs EtBr-exposed(maintained under normal lab light (mostly dark, in incubators) and exposed to EtBr (5ug/mL in agar).) at 3 h after the third UVC dose (51h), which is also 3 h after being placed on food. Genes differentially expressed under UVC exposure and EtBr treatment vs under EtBr treatment but without UVC exposure at the -3h timepoint (3 h after the third UVC dose (51h), which is also 3 h after being placed on food). Transcripts were defined as fold-change >1.2, p < 0.05 based on Rosetta Resolver analysis for all pairwise treatment comparisons. The fold-change refers to the second intensity over the first.
