WormBase Gene ID  ? WBGene00000441 Gene Name  ceh-18
Sequence Name  ? ZC64.3 Brief Description  ceh-18 encodes a POU-class homeodomain transcription factor; CEH-18 is required in hermaphrodites for specific aspects of gonadal sheath cell differentiation, such as normal cell shape and position, that are essential for negative regulation of oocyte meiotic maturation by the sheath cells; in this process, CEH-18 functions in parallel with the VAB-1/Ephrin receptor as part of a sperm-sensing checkpoint mechanism that prevents oocyte maturation, MAPK activation, and ovulation in the absence of sperm; CEH-18 is expressed in the sheath cell nuclei beginning at the L4 larval stage
Organism  Caenorhabditis elegans Automated Description  Predicted to enable DNA-binding transcription factor activity, RNA polymerase II-specific and RNA polymerase II cis-regulatory region sequence-specific DNA binding activity. Involved in several processes, including determination of adult lifespan; gamete generation; and negative regulation of oocyte maturation. Located in nucleus. Expressed in body wall musculature; gonad; neurons; non-striated muscle; and somatic nervous system. Is an ortholog of human POU2F2 (POU class 2 homeobox 2) and POU2F3 (POU class 2 homeobox 3).

  Transcripts that showed significantly increased expression in L1 neural cells comparing to in adult neural cells. DESeq2 (v1.18.1) fold change > 2, P-adj<0.05, using BenjaminiHochberg correction. WBPaper00060811:L1_vs_adult_upregulated_neural
  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
  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_upregulated
  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 that showed significantly increased expression glp-1(e2141); TU3401 animals comparing to in TU3401 animals. Fold change > 2, FDR < 0.01. WBPaper00065993:glp-1(e2141)_upregulated
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.

  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 expression level regulated by genotype (N2 vs CB4856) and age at L3 larva and Late reproduction stage (96 hours at 24 centigrade). For model 2, authors used 100 permutations to estimate the FDR threshold. Per permutation, genotypes and ages were independently randomly distributed, keeping the among-gene structure intact. Then for each spot (23,232) on the array, model 2 was tested. The obtained P-values were used to estimate a threshold for each of the explanatory factors. Authors also used a genome-wide threshold of -log10 P-value = 2, which resembles an FDR of 0.072 and 0.060 for marker and the interaction age-marker for the developing worms and FDR of 0.050 and 0.065 for marker and age-marker for the aging worms. For the physiological age effect, authors used a log10 P-value = 8 in developing worms (0.012 FDR) and -log10 P-value = 6 (0.032 FDR). WBPaper00040858:eQTL_age_regulated_developing

  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. 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.

  Transcripts that showed significantly increased expression after four-day-old young adult worms were placed on NGM plates seeded with OP50 in the presence 5% Agaro-oligosaccharides(AGO) for 24 h, comparing to animals grown in the absence of AGO.

  Transcripts that showed significantly increased expression in alg-1(gk214), comparing to in N2. DESeq2, Fold change > 1.5. WBPaper00051404:alg-1(gk214)_upregulated
  Genes that showed significantly increased expression in daf-2(e1370) comparing to in N2. To identify DEGs, Students t test and the log2 median ratio test were performed to compute t values and median ratios for all the annotated genes. The adjusted P values from each test were computed using an empirical distribution of the null hypothesis, which was obtained from random permutations of the samples. Finally, the adjusted P values from the individual tests were combined to compute the overall P values using Stouffers method , and genes with overall P < 0.05 and fold change > 1.5 were selected as DEGs.

  Genes that showed increased expression after nicotic acid (NA) treatment. Raw counts for the genes were analyzed using the R Statistical Computing Environment and the Bioconductor packages DESeq and edgeR. Both packages provide 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 Hochberg's approach for controlling the false discovery rate (FDR). If both FDR values (by DESeq and edgeR) were smaller than p = 0.05, genes were assigned as differentially expressed. WBPaper00044260:nicotinc-acid_upregulated
