WormBase Gene ID  ? WBGene00001697 Gene Name  grd-8
Sequence Name  ? C37C3.4 Brief Description  grd-8 encodes a hedgehog-like protein, with an N-terminal signalsequence, a central low-complexity proline-rich domain, and a C-terminalGround domain; GRD-8 is expressed in larval intestine and neurons; thegrd-8 gene is directly bound by DAF-12 and requires DAF-12 for fulltranscription; GRD-8's Ground domain is predicted to form acysteine-crosslinked protein involved in intercellular signalling, andit has subtle similarity to the N-terminal Hedge domain of HEDGEHOGproteins; GRD-8 is weakly required for normal molting; GRD-8 is alsorequired for normal adult alae formation, growth to full size,locomotion, and male tail development; all of these requirements mayreflect common defects in cholesterol-dependent hedgehog-like signallingor in vesicle trafficking.

  Coexpression clique No. 203, sre-33-ZK1025.1_8337, 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.

  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.

  Genes with significantly increased expression in eat-2(ad465) treated with 2% DMSO for 72 hours, comparing to in N2 treated with 2% DMSO for 72 hours. Analysis of gene expression data was carried out with the Affymetrix Transcriptome Analysis Console. Data preprocessing (using RMA normalization) and QC metrics were performed using Affymetrix Expression Console TM and manually inspected afterwards. Expression analysis was carried out for each two pairwise conditions. FDR statistical correction for multiple testing resulted in a slightly lower number of DEGs in most cases. P-value < 0.05 and fold change > 2.0 were used to determine differentially expressed genes. WBPaper00048989:eat-2(ad465)_upregulated_in-DMSO

  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. WBPaper00046548:dafachronic-acid_downregulated

  Genes enriched in intestine. To identify genes that are significantly enriched by mRNA tagging, we first normalized the total amount of Cy3 and Cy5 signal to each other in each hybridization. We measured the ratio of the signals from the co-immunoprecipitated mRNA (Cy5) to total RNA in the cell extract (Cy3), and calculated the percentile rank for each gene relative to all genes in each hybridization. The mean percentile rank was determined from eight repeats of the mRNA-tagging experiment. Student's t-test was used to determine which genes showed a mean enrichment significantly greater than the median enrichment for all genes (P<0.001). WBPaper00026980:intestine_enriched
  Transcripts that showed significantly decreased expression in mex-1(or286) comparing to in N2 at early embryo when there were only 3 -5 eggs in the adult. RPKM fold change > 2. WBPaper00058598:mex-1(or286)_downregulated

  Transcripts that showed significantly decreased expression in drh-3(rrr2) comparing to in N2. edgeR, log2 fold change > 2 or < -2. WBPaper00053888:drh-3(rrr2)_downregulated
  Potental DAF-12 target genes identified by ChIP-chip analysis performed on strain ALF4 [daf-12 Affymetrix TAS software that computed for each probe estimates of fold enrichment (in linear scale) over hybridization with input DNA. At the same time, TAS calculated for each probe a p-value by applying a Wilcoxon signed rank test. A threshold of 2.5 was selected, which corresponds to probe intensities approximately 2.5 times stronger on the ChIP array than on the Input array. Additional TAS threshold parameters were MinRun=180 bp, MaxGap=300 bp. TAS analysis showed that the selected threshold of 2.5 corresponds approximately to a p-value of 0.01.

  Transcripts that showed differential expression between 24 and 26 hours post hatching L2d and dauer committed larvae of daf-9(dh6), triggered by the dafachronic acid (DA) growth hormone. Cluster 4 genes increased expression transiently during dauer commitment. Benjamini Hochberg corrected q-value < 0.01. WBPaper00053388:dauer_regulated_Cluster4
  Genes that showed decreased expression after exposure to 7.5uM CH3HgCl for 24 hours. Rosetta Resolver was used to identify differentially expressed genes using an error-weighted, 1-way ANOVA with a Bonferroni correction. A 2-fold change in expression, relative to untreated controls, and a p-value < 0.01 was required for a gene to qualify as significantly, differentially expressed.

Expression analysis was carried out for each two pairwise conditions. FDR statistical correction for multiple testing resulted in a slightly lower number of DEGs in most cases. P-value < 0.05 and fold change > 2.0 were used to determine differentially expressed genes. WBPaper00048989:N2_allantoin_upregulated
