WormBase Gene ID  ? WBGene00000522 Gene Name  clc-1
Sequence Name  ? C09F12.1 Brief Description  clc-1 encodes a claudin homolog, closely similar to CLC-2, that is required for normal cohesion of apical junctions in epithelia; claudins are integral membrane proteins with four transmembrane sequences that are found in mammalian tight junctions (TJs), induce TJs when transgenically expressed in cells normally lacking them, and can mediate the specific conductance of of specific ions (e.g., magnesium or calcium) through TJs while blocking the flow of water; CLC-1 maintains the impermeability ('barrier function') of epithelia, since clc-1(RNAi) animals have abnormal permeability of the pharynx to dyes; clc-1 is expressed in spermatheca, pharynx, intestine, hypodermis, the excretory-secretory system, and the cell-cell junctions of the vulva; in pharyngeal cells, CLC-1 colocalizes with AJM-1 in long thin lines, parallel to the pharyngeal axis and lining the lumenal surface, that appear to correspond with apical intercellular junctions.
Organism  Caenorhabditis elegans Automated Description  Involved in defense response to Gram-positive bacterium; epithelial cell-cell adhesion; and innate immune response. Located in cell-cell junction. Expressed in pharynx.
Biotype  SO:0001217 Genetic Position  X :2.85734 ±0.000156

  mRNAs that showed decreased expression in 1 cell mebryo comparing to in oocyte, according to RNAseq analysis. Gaussian error propagation. As cutoff for the up-regulated genes authors used log2 fold change > 1 and P < 0.05 and as cutoff for the down-regulated genes authors used log2 fold change < -1 and P < 0.05.

  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

  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. 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_SM

  Significantly differentially expressed genes as determined by microarray analysis of wild-type and cde-1 mutant germlines. RNAs that changed at least 2-fold with a probability of p < 0.05 were considered differentially regulated between wildtype and cde-1. WBPaper00035269:cde-1_regulated

  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 with an adjusted p-value smaller 0.05 were assigned as differentially expressed. WBPaper00044426:rotenone_24h_upregulated
Starvation Starvation-induced transcripts that showed significantly increased expression in post dauer animals comparing to wild type control. edgeR WBPaper00053713:Starvation-induced_postdauer_vs_control_upregulated
  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. WBPaper00037950:A-class-motor-neurons_L2-larva_expressed
  Genes that showed oscillating mRNA expression level throughout the 16 hour time courses from L3 larva to young adult. The following three lines of R code were used to perform the classification: increasing <-2*amplitude-PC1 < -1.7; oscillating <-!increasing & (amplitude > 0.55); flat <-!increasing & !oscillating; Note that the amplitude of a sinusoidal wave corresponds to only half the fold change between trough and peak. WBPaper00044736:oscillating_dev_expression
  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).

This distribution of CLC-1 was confirmed by whole-mount immunofluorescence staining with antiCLC-1 pAb, although the staining signals were not so intense.   Expr2559 Intense GFP signals were detected as lines from the pharyngeal region of the digestive tubes in addition to other types of cells. The pharyngeal region of the digestive tubes can be subdivided into four portions: procorpus, metacorpus, isthmus, and terminal bulb. Among them, the procorpus and isthmus portions are elongated. In both portions, three parallel GFP-positive lines (occasionally one or two additional lines in the isthmus portion) were observed to run longitudinally and to surround the interior lumen. Close inspection revealed that each of these thick lines occasionally resolved into two thinner lines. These findings suggested that CLC-1 is expressed in the epithelial cells of the pharyngeal region of the digestive tubes and is concentrated at the intercellular junctions located at the most apical portion of the lateral membranes. Intercellular junctions located at the most apical portion of the lateral membranes.
