Osmotic stress	Transcripts that showed significantly altered expression with 500 mM salt (NaCl) vs 100 mM salt when food was present	DESeq(version 1.10.1), FDR < 0.05.	WBPaper00050726:OsmoticStress_regulated_Food
	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.

	Transcripts expressed in intestine, according to PAT-Seq analysis using Pges-1-GFP-3XFLAG mRNA tagging.	Cufflinks FPKM value >=1.	WBPaper00050990:intestine_expressed
	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 that showed significantly decreased expression in tetraploid N2 comparing to diploid N2 animals at L4 larva stage.	DESeq2 R package (1.20.0), fold change > 2, and FDR < 0.05.	WBPaper00066110:tetraploid_vs_diploid_downregulated
	Genes that showed expression levels higher than the corresponding reference sample (L3/L4 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.

• Primary Identifier: Expr14296
• Pattern: To gain insight into the role of AP endonucleases a er embryogenesis, we measured the temporal change in the mRNA expression level of exo-3 or apn-1. At 0, 24 and 48 hours, when most N2 worms are in the egg stage, L1 stage and L4 stage, respectively, no di erence in mRNA expression level was found for both exo-3 and apn-1. At 60 hours, when most N2 worms are in the young adult stage, the exo-3 and apn-1 expression levels were approximately 13-fold and 2.3- fold higher than those at 0 hours, respectively. e expression level at 72 hours, when most N2 worms are in the gravid adult stage, was the same at 60 hours. These results suggest that AP endonucleases are required after embryogenesis, especially a er the L4 stage.
