WormBase Gene ID  ? WBGene00002393 Gene Name  lpr-1
Sequence Name  ? Y65B4BR.2 Brief Description  lpr-1 encodes one of seven C. elegans proteins related to the lipocalin family of structurally related, low molecular weight, secreted proteins that bind and transport lipophilic molecules and participate in intercellular signaling; in C. elegans, LPR-1 activity is required for connectivity between the lumens of two unicellular tubes in the nematode excretory system formed by the excretory duct cell and pore cell; LPR-1 functions cell non-autonomously and its activity is required during the comma stage of embryogenesis; an lpr-1::GFP promoter fusion is expressed beginning at the comma stage of embryogenesis and continues through larval development; expression is seen in the excretory duct cell, pore cell, and the G2 cell, as well as in hyp7, the hypodermal seam cells, and P cells.
Organism  Caenorhabditis elegans Automated Description  Involved in nematode larval development and tube development. Predicted to be located in extracellular region. Expressed in several structures, including P1; P12; P2; excretory system; and hypodermal cell.
Biotype  SO:0001217 Genetic Position  I :-18.9527 ±0.003336

  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

  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.

  Transcripts that showed significantly increased expression in hda-1(ne4752[3xFLAG-Degron-HDA-1]) in gonads dissected from 1-day old adult animals. Salmon was used to map the mRNA-seq reads with the worm database WS268, and its output files were imported to DESeq2 in R. The differentially expressed genes were filtered by fold change more than 2 and adjusted p-value < 0.05. The scatter plots were generated by the plot function in R.

  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). 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:hypodermis_L3-L4-larva_expressed
  Genes significantly enriched (> 2x, FDR < 5%) in a particular cell-type versus a reference sample of all cells at the same stage. 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.

Picture: Figure 8.   Expr8580 Consistent lpr-1::GFP expression initiates immediately after the comma stage of embryogenesis and continues throughout the remainder of embryonic and larval development. At the three-fold stage of embryogenesis, lpr-1::GFP is expressed within both the excretory duct cell and pore cell, and in G2, which adopts excretory pore cell function later in development. Authors observed no expression within the excretory canal cell. lpr-1::GFP is also expressed in hyp7, seam cells, and P cells, all of which are epidermal cell types that surround the excretory system.  
    Expr13230 LPR-1 localizes to both intracellular and apical extracellular compartments. Secreted protein. When driven by the lpr-1 promoter, all fusions rescued lpr-1 lethality and were detected within the duct and pore cells and other external epithelia beginning at the 1.5-fold stage. The fusions were also secreted apically between the embryo and the eggshell and appeared enriched in or near the duct and pore lumens at the 3-fold stage.  
    Expr2013259 Single cell embryonic expression. Only cell types with an expression fraction of greater 0.2 of the maximum expressed fraction are labeled (Full data can be downloaded from http://caltech.wormbase.org/pub/wormbase/datasets-published/packer2019/). The colors represent the broad cell class to which the cell type has been assigned. The size of the point is proportional to the log2 of the numbers of cells in the dataset of that cell type. Interactive visualizations are available as a web app (https://cello.shinyapps.io/celegans/) and can also be installed as an R package (https://github.com/qinzhu/VisCello.celegans).  
    Expr14487   LPR-1::SfGFP was only variably visible in the embryonic excretory duct/pore lumen (Pu et al. 2017), which is open to the extraembryonic environment, but was more robustly observed in the developing vulval lumen, which is a closed compartment. LPR-1::SfGFP filled the entire vulva lumen and did not appear to associate specifically with any glycocalyx layer.
