WormBase Gene ID  ? WBGene00022277 Gene Name  homt-1
Sequence Name  ? Y74C9A.3 Brief Description  homt-1 encodes a putative hydroxyindole-O-methyltransferase orthologous to human C1orf184 and C9orf32; by homology, HOMT-1 is expected to catalyze the conversion of N-acetyl serotonin to melatonin; homt-1 is expressed in the tail neuron PVT, and in uterine cells; since exogenous melatonin slows C. elegans locomotion and enhances slowing by food, Y74C9A.3 may inhibit locomotion.
Organism  Caenorhabditis elegans Automated Description  Predicted to enable N-terminal protein N-methyltransferase activity. Predicted to be involved in methylation. Predicted to be located in cytoplasm. Expressed in PVT and uterus. Is an ortholog of human NTMT1 (N-terminal Xaa-Pro-Lys N-methyltransferase 1).

  WT-Pico Pan-neural Depleted Genes, with genes found multiple times in a single dataset removed (without dups). To identify differentially expressed transcripts, normalized intensity values from the pan-neural data sets were compared to a reference (from all larval cells) using Significance Analysis of Microarray software (SAM). A two class unpaired analysis of the data was performed to identify neuron-enriched genes. Pan-neural enriched transcripts in the IVT and WT-Pico-derived data set were defined as 1.5X elevated vs the reference at a False Discovery Rate (FDR) = 3%. WBPaper00031532:Larva_Pan_Neuronal_Depleted
  Transcripts with significantly increased expression in nuo-6(qm200) vs. N2, and in nuo-6(qm200);ced-4(n1162) vs. ced-4(n1162). Comparisons of each genotype were compared to the wild-type using the Empirical Base (Wright & Simon) algorithm and fold changes were represented on a log2 scale. A threshold of p < 0.05 and a fold change of 1.3 (log2) was set to determine differentially expressed targets. WBPaper00045263:nuo-6(qm200)_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 depleted expression in sensory neuron (labeled by iaIs25[Pgcy-37::GFP + unc-119(+)]) comparing to in whole worm. Fold change > 2, p-value < 0.05. WBPaper00060661:sensory-neuron_depleted
Exposure to Au-NP. Genes with differeiential expression after exposed to Au-NP. Hierarchical clustering was performed in Partek to confirm that the samples match to the treatment groups. Analysis of variance (ANOVA) was used to partition the variance due to treatment from technical and biological noise. The list of differentially expressed genes was generated by identifying the genes showing fold change of more than 1.5 and less than -1.5 at p < 0.05 with and without multiple sample correction, False Discovery Rate (FDR). False discovery correction according to Benjamini and Hochberg produced a list of 37 significant transcripts. FDR was not applied when selecting differential expressed genes, because this approach can increase the type II error and result in elimination of the genes responsive to the treatment. WBPaper00040821:Au-NP_regulated
  Genes depleted in muscle cells (24hr muscle dataset). Dissociated myo-3::GFP embryos were cultured for 24 hours before FACS sorting. 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.
