  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
  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

Bacteria infection: Photorhabdus luminescens Genes down-regulated in animals infected with Photorhabdus luminescens compared to the E. coli OP50 control after 24h of infection. MAANOVA and BRB-Array-Tools. WBPaper00030985:Photorhabdus_luminescens_downregulated
  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

  Proteins that showed significantly decreased expression after 1-day-old wild type adults were exposed to cisplatin (300ug per mL) for 6 hours.

  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
  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
  Transcripts that showed significantly altered expression after 24 hour exposure to stavudine (FLT) starting at L1 lava stage. DESeq WBPaper00053302:alovudine_24h_regulated
  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.

  Embryonic A-class motor neuron enriched genes. A two-class unpaired analysis of the data was performed to identify genes that differ by >= 1.5-fold from the reference at a FDR of <1% for the larval pan-neural, embryonic pan-neural, and larval A-class motor neuron datasets. WBPaper00030839:Embryo_A_Class
  Transcripts enriched in germline by comparing dissected germline tissue with dissected intestine tissue, both injected with empty RNAi vector. Genes were determined germline-enriched if the lowest expression value (log2(FPKM+1)) observed in the germline empty vector samples was at least 2-fold higher than the highest expression value observed in the intestine empty vector samples. WBPaper00051039:germline_enriched
Bacteria infection: Xenorhabdus nematophila Caenorhabditis elegans Genes with expression levels changed significantly after treatment of Xenorhabdus nematophila. Differential expression were calculated by empirical eBayes method using eBayes function. P_value <= 0.01 and log2 fold change > 1 were used to call differentially expressed genes in all datasets.
