Genes that were upregulated in lin-15B(n744). |
For each gene in each microarray hybridization experiment, the ratio of RNA levels from the two samples was transformed into a log2 value and the mean log2 ratio was calculated. The log2 ratios were normalized by print-tip Loess normalization (Dudoit and Yang, 2002). All genes with a false discovery rate of <= 5% (q <= 0.05) (Storey and Tibshirani, 2003) and a mean fold-change ratio of >= 1.5 were selected for further analysis. |

Bacteria infection: Enterococcus faecalis |
Genes with increased expression after 24 hours of infection by E.faecalis Fold changes shown are pathogen vs OP50. |
For RNA-seq and tiling arrays, log2 fold changes between gene expression values of infected versus uninfected nematodes were calculated. 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 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. |

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. |

heat-shock hlh-1 |
Genes enriched in HLH-1 heat shock dataset. |
A two-class unpaired analysis was performed to identify genes that are elevated 1.7-fold or greater when compared with the reference for each dataset, at a false discovery rate of 1.8% or less for M0 and 1.2% or less for the M24 datasets. |

Genes that showed significantly decreased experssion after 22.5 hours of treatment in 200nM delta7-dafachronic acid comparing with in ethanol vehicle control. |
To identify the differentially expressed genes, we applied Significance Analysis of Microarrays (SAM) analysis using the R package samr [46]. Genes with median false discovery <5% and fold changes >2.0 were considered differentially expressed. |

control(maintained under normal lab light (mostly dark, in incubators).) vs UVC-exposed(exposed to 7.5 J/m2 UVC radiation 3 times, 24 h apart (48 h total).) at 3 h after the third UVC dose (51h), which is also 3 h after being placed on food. |
Genes differentially expressed in control vsafter UVC exposure without EtBr treatment, 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. |

Genes in the bottom 10% of expression level across the triplicate L3 samples. To generate the top10 and bottom10 gene sets, authors ranked all genes by mean expression array signal intensity across the three replicates, then took the top and bottom deciles (1,841 genes each) to represent genes with high and low expression. |

Coexpression clique No. 211, srj-42-srw-113, on the genome-wide coexpression clique map for the nematode GPL200 platform. |
All available microarray datasets for the GPL200 platform (Affymetrix C. elegans Genome Array) were obtained from the GEO repository. This included 2243 individual microarray experiments. These were normalized against each other with the software RMAexpress (Bolstad, 2014). Based on these normalized values, Pearsons correlation coefficients were obtained for each probe-probe pair of the 22,620 probes represented on this array type. The resulting list of correlation coefficients was then ranked to generate the ranked coexpression database with information on each probe represented on the GPL200 platform. |
