WormBase Gene ID  ? WBGene00003888 Gene Name  osm-8
Sequence Name  ? R07G3.6 Brief Description  osm-8 encodes a mucin-like secreted protein with a PST (proline/serine/threonine) domain similar to the PST domain in human mucin, Muc2; osm-8 is a negative regulator of the osmotic stress response, mutants for osm-8 show inappropriate activation of physiological responses to osmotic stress; osm-8 acts through the hypodermally expressed transmembrane protein PTR-23 to activate osmosensitive gene expression, glycerol accumulation and other responses to osmotic stimuli; osm-8 is expressed in the hypodermis and is most likely secreted from the hypodermal apical membrane.
Organism  Caenorhabditis elegans Automated Description  Involved in regulation of gene expression and response to osmotic stress. Located in extracellular space. Expressed in hyp7 syncytium.
Biotype  SO:0001217 Genetic Position  II :0.5056±

  Genes with expression level regulated by genotype (N2 vs CB4856) 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_regulated_developing

  Genes regulated by DAF-12, according to whole transcriptome profiling to compare genome-wide regulatory influences of DPY-21 and SET-4 to those of the key transcription factors controlling dauer arrest in eak-7;akt-1 animals, DAF-16 and DAF-12. Authors identified genes differentially expressed between wild-type and eak-7;akt-1 double mutant animals [fold change >= 1.5 and false discovery rate (FDR) < 0.05]. Authors then compared the transcriptomes of eak-7;akt-1 double mutants to those of eak-7;akt-1 animals harboring mutations in dpy-21, set-4, daf-16, or daf-12, and identified genes that are differentially expressed in the opposite direction as in wild-type relative to eak-7;akt-1. Annotated gene expression data output from CuffDiff v2.2.1 was read into R version 3.2.1 for six comparisons: eak-7;akt-1 compared to (1) wild-type, (2) daf-16(mu86);eak-7;akt-1, (3) daf-12;eak-7;akt-1, (4) set-4(n4600);eak-7;akt-1, (5) set-4(dp268);eak-7;akt-1, and (6) dpy-21;eak-7;akt-1. Authors filtered genes by the following criteria: (1) status = OK for wild-type vs. eak-7;akt-1, (2) fold change (FC) >= 1.5 or FC <= 1/1.5 for wild-type vs. eak-7;akt-1 and (3) FDR < 0.05 for at least two separate comparisons.

    Expr1031831 Tiling arrays expression graphs  
    Expr11207 The osm-8 promoter is only expressed at detectable levels in the hypodermis. GFP expression was observed in the hypodermal syncitium and was excluded from the hypodermal seam cells. While the osm-8 promoter was active in larval stages up to and including the L4, expression in adults was strongly attenuated, suggesting that osm-8 mRNA expression might be developmentally regulated. Indeed, quantitative RT-PCR analysis of osm-8 mRNA showed weakly oscillating expression levels that were similar to the expression levels in another secreted protein, the collagen gene dpy-7.
