WormBase Gene ID  ? WBGene00003475 Gene Name  mtm-1
Sequence Name  ? Y110A7A.5 Brief Description  mtm-1 encodes a myotubularin lipid phosphatase orthologous to human MTM1, MTMR1, and MTMR2; MTM-1 activity is required for negative regulation of endocytosis and apoptotic cell engulfment; mtm-1(RNAi)suppresses the endocytosis defect seen in animals with mutations in let-512 mutants, which encodes a phosphatidylinositol 3-kinase orthologous to yeast Vps34; MTM-1 localizes to the plasma membrane.
Organism  Caenorhabditis elegans Automated Description  Enables phosphatidylinositol-3,5-bisphosphate 3-phosphatase activity; phosphatidylinositol-3-phosphate phosphatase activity; and phosphatidylinositol-4,5-bisphosphate binding activity. Involved in negative regulation of engulfment of apoptotic cell and phospholipid dephosphorylation. Located in apical cortex; cytosol; and plasma membrane. Expressed in several structures, including coelomocyte; hermaphrodite somatic gonadal cell; neurons; pharynx; and vulva. Used to study centronuclear myopathy. Human ortholog(s) of this gene implicated in Charcot-Marie-Tooth disease type 4B1 and congenital structural myopathy. Is an ortholog of human MTM1 (myotubularin 1); MTMR1 (myotubularin related protein 1); and MTMR2 (myotubularin related protein 2).

  Genes with expression level regulated by genotype (N2 vs CB4856) and age at old adults stage (214 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_aging

  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.

  Expression Pattern Group B, enriched for genes involved in embryonic development. These patterns have in common that they all have genes of which the expression goes up after the juvenile stage. The expression of the genes in these patterns remains high or even goes up after reproduction. The significance (P 0.0001) of the relative age (time) was used to determine if a gene was differentially expressed between the three age (time) groups. The effect of this factor explaining gene expression differences was used to determine if the expression went up or down during the two age/time periods (t1 - t2 and t2 -t3). Authors used a permutation approach to determine the thresholds for the different mapping strategies. For each of the used models for eQTL mapping, authors used 23,000 permutations. For each permutation, authors randomly picked a spot; each spot could only be picked once. The gene expression and relative lifespan values were than randomly distributed over the RILs (and time points) and used for mapping. In this way, authors obtained a threshold for each of the explaining factors. For the single time points, authors used a FDR of 0.01 to adjust for multiple testing. The genome-wide threshold for this FDR is -log10 P = 3.8 for each of the three time points. For the combined models (t1 to t2 and t2 to t3), authors used a genome-wide threshold of -log10 P = 4, which resembles an FDR of 0.006, 0.001, and 0.006 for marker, age, and the interaction between marker and age, respectively. To determine the threshold for the single gene examples, authors used 1000 permutations as in the genome-wide threshold. The difference is that they use the gene under study in all of the permutations. The P-values for the gene specific thresholds were determined at FDR = 0.05. WBPaper00036286:Pattern_B
Wounding: 2 hours after a single stab of a microinjection needle to either anterior or posterior body of lateral hyp7 (avoid the gonad) 24 hr after the L4 stage. Transcripts that showed significantly increased expression 2 hours after animals had a single stab of a microinjection needle to either anterior or posterior body of lateral hyp7 (avoid the gonad) 24 hr after the L4 stage. The cutoff for differential expressed genes (DEGs) were: Benjamini-Hochberg adjustedP-valueless than 0.05 and fold change larger than 1.5. WBPaper00059987:Wounding_upregulated

    Expr9266 In larvae, broad MTM-1 expression is observed in L1 heads, particularly in pharynges. In adults, MTM-1 is expressed in coelomocytes and in the gonadal sheath cells. MTM-1 is broadly expressed at the apical cortex of gut cells and around gut granules. As previously reported, MTM-1 was also expressed in a few head and tail neurons. MTM-1 is abundantly expressed at the cell cortex (e.g. on the apical membrane of intestinal cells) with the rest of the protein being distributed throughout the cytosol.
Picture: Figure 7B.   Expr8826   By time-lapse analysis, GFP::MTM-1 and CED-1::mCHERRY appeared on the surface of dying cells simultaneously during the early stage of engulfment (Figure 7B). However, GFP::MTM-1 disappeared more quickly than CED-1::mCHERRY from the phagosome after internalization.
Picture: Figure 6A, .   Expr8825 The expression of MTM-1::GFP was seen from embryogenesis throughout larval and adult stages in many known engulfing cell types including hypodermal cells, body wall muscle cells, pharyngeal muscle cells and sheath cells. MTM-1::GFP was also observed in vulva cells, distal tip cells and coelomocytes. MTM-1::GFP is mainly localized to the plasma membrane and coincides with myri::mCHERRY, which specifically labels cell membranes.
