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
	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 that showed significantly increased expression in csr-1a(tor159) comparing to in N2 at 25C.	DESeq2, fold change > 2, p-value < 0.05.	WBPaper00061753:csr-1(tor159)_upregulated_25C
	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.

	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
	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.

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.

	Transcripts of coding genes that showed significantly increased 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_enriched_coding-RNA
	Transcripts down regulated in hpl-2(tm1489) embryo comparing to N2 in tiling array analysis.	Oligos from the tiling array were mapped to chromosome coordinates of the exons from Wormbase WS180. Any oligo that mapped to a gene on both the Watson and Crick strands was excluded. The remaining oligos were then grouped together (perfect match and mismatch) into probe sets and written out into an Affymetrix CDF file. The CDF file was converted into an R-package and loaded into R. The expression values were calculated using the justRMA function from Bioconductor. This used a Benjamini and Hochberg false discovery rate correction.	WBPaper00040560:hpl-2_embryo_downregulated

8 Expression Patterns

• Primary Identifier: Expr4890
• Remark: Picture: Fig 5.
• Pattern: Several globin genes (C06E4.7, C09H10.8, C36E8.2, C52A11.2, F52A8.4, R01E6.6, R13A1.8, R90.5, and W01C9.5) are similarly upregulated in L3 and dauers relative to young adults, although some reach significance in dauers only. Many genes exhibited more than 2- fold upregulation but didn't reach statistical significance because strong upregulation was only seen in 2 biological replicates, A significant downregulation in L3 stage relative to young adults was observed for C26C6.7, T22C1.2 and ZK637.13. A similar trend was seen in dauers. C26C6.7 was the only globin which exressed at a significantly higher level in dauers relative to L3. Quantitative real-time RT-PCR experiments were done to compare the relative bundance of all 33 globins in wild type adults. Results demonstrate T22C1.2 and ZK637.13 are expressed at substantially higher levels. The difference with the other globins ranges within 1-3 orders of magnitude.

• Primary Identifier: Expr8506
• Remark: Picture: Figure 4.
• Pattern: Expressed in head mesodermal cell, stomato-intestinal muscle.

• Primary Identifier: Expr10701
• Pattern: GLB-26 is expressed in the head mesodermal cell, and in the tail in the stomato-intestinal and anal depressor muscle cell. GLB-26 was also found to be expressed in the male anal depressor muscle. The expression pattern observed here is in accordance with the results of a localization study conducted by Hoogewijs and coworkers, who used a transcriptional reporter.
• Subcellular Localization: In the head region expression is seen in the head mesodormal cell, with apparent enrichment in the nucleus. This reporter shows that GLB-26 is membrane bound.
