WormBase Gene ID  ? WBGene00009834 Gene Name  lsy-27
Sequence Name  ? F47H4.1 Brief Description  lsy-27 encodes a nematode specific, fast evolving family of C2H2 zinc finger transcription factor; lsy controls the left/right asymmetric expression of gcy genes; lsy-27 acts during the initiation, but not maintenance phase of ASE laterality control, to assist in the initiation of lim-6 expression; lsy cooperates with ASEL-expressed die-1 to trigger lim-6 expression in the embryo; LSY-27 is broadly expressed in the embryo from one cell to comma stage, in ASE neurons at comma stage.
Organism  Caenorhabditis elegans Automated Description  Predicted to enable DNA-binding transcription factor activity, RNA polymerase II-specific and sequence-specific DNA binding activity. Involved in neuron differentiation and regulation of DNA-templated transcription. Predicted to be located in nucleus. Expressed in ASE; embryonic cell; head; somatic nervous system; and tail neurons.

  Genes with expression altered >= 3-fold in dpy-10(e128) mutants. Data across the wild type series was analyzed using the Significance analysis of Microarrays (SAM) algorithm (to calculate the False Discovery Rate (FDR)). WBPaper00035873:dpy-10_regulated

  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

  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 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 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.

  Transcripts that showed significantly decreased expression in hpl-2(tm1489) comparing to in N2 animals. DESeq2, adjusted p-value < 0.05, log2 fold change > 2 or < -2. WBPaper00054493:hpl-2(tm1489)_downregulated

15 Expression Patterns

Remark Reporter Gene Primary Identifier Pattern Subcellular Localization
Clone: pUL#JRH/AE11   Expr7574 From 100-cell embryo to hatching, all cells express strongly. Post hatching can see expression in dorsal and ventral nerve cords plus a dorsal cell body near the terminal bulb of pharynx; four nerve cells in tail; two lateral cells adjacent to terminal pharyngeal bulb; two lateral cells adjacent to the metacorpus of the pharynx. Also weak expression in anterior head muscles in all stages post-hatching.  
    Expr11402 lsy-27 is expressed very broadly throughout the embryo. Expression can already be observed in one-cell embryos and continues to about the comma stage, when expression starts to fade out. By the comma stage, most neurons, including ASEL/ASER, have terminally divided and begun to terminally differentiate. No expression is observed after hatching in larvae or in adult animals. Through colocalizing expression of the lsy-27 reporter with an ASE-specific mCherry reporter, we confirmed that lsy-27 is expressed in both ASE neurons in the comma-stage embryo when ASE laterality is established.

    Expr10357 Inferred expression. EPIC dataset. http://epic.gs.washington.edu/ Large-scale cellular resolution compendium of gene expression dynamics throughout development. This reporter was inferred to be expressing in this cell or one of its embryonic progenitor cells as described below. To generate a compact description of which cells express a particular reporter irrespective of time, the authors defined a metric "peak expression" for each of the 671 terminal ("leaf") cells born during embryogenesis. For each of these cells, the peak expression is the maximal reporter intensity observed in that cell or any of its ancestors; this has the effect of transposing earlier expression forward in time to the terminal set of cells. This metric allows straightforward comparisons of genes' cellular and lineal expression overlap, even when the expression occurs with different timing and despite differences in the precise time point that curation ended in different movies, at the cost of ignoring the temporal dynamics of expression, a topic that requires separate treatment. For simplicity, the authors use the term "expressing cells" to mean the number of leaf cells (of 671) with peak expression greater than background (2000 intensity units) and at least 10% of the maximum expression in that embryo.
