WormMine: Gene WBGene00003007

• WormBase Gene ID: WBGene00003007
• Gene Name: lin-18
• Sequence Name: C16B8.1
• Brief Description: lin-18 encodes a predicted receptor tyrosine kinase that is a member of the Ryk/Derailed family of tyrosine kinase-related receptors (OMIM:600524, mutations in humans are associated with cleft palate); in C. elegans, LIN-18 is required for establishing the polarity of the secondary vulval cell lineage produced by the P7.p vulval precursor cell; LIN-18 may be a receptor for Wnt-like signaling molecules, and in vulval development appears to function independently of, but in parallel with, LIN-17, a Frizzled-like Wnt receptor, also required for proper orientation of the P7.p lineage; a lin-18 reporter gene is expressed in body wall muscle, neurons, and the developing vulva; in the vulva, expression is detected in P5.p, P6.p, and P7.p and all of their descendants during the L3 and L4 larval stages.
• Organism: Caenorhabditis elegans
• Automated Description: Predicted to enable transmembrane receptor protein tyrosine kinase activity. Involved in several processes, including asymmetric protein localization involved in cell fate determination; axis specification; and positive regulation of axon guidance. Located in cytoplasm; nucleus; and plasma membrane. Expressed in body wall musculature; neurons; vulva; and vulval precursor cell. Is an ortholog of human RYK (receptor like tyrosine kinase).

Reduced humidity (98% relative humidity).	Genes that were down-regulated after one day exposure to reduced humidity (98% relative humidity) according to microarray analysis.	Multiple hypothesis testing with the Benjamini-Hochberg correction was applied on calculated p-values.

	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.

Differentially-expressed genes (DEG) were identified based on two criteria: FDR (False discovery rateusing Benjamini-Hochberg adjusted p-values) < 0.01 and absolute value of log2(Fold Change) > 1.

	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).

7 Expression Patterns

• Primary Identifier: Expr1031402
• Pattern: Tiling arrays expression graphs

• Primary Identifier: Expr3049
• Remark: Reporter gene fusion type not specified.
• Pattern: Expression from both extrachromosomal arrays and chromosomal integrants was observed, and the results were fully consistent. LIN-18::GFP was expressed in neurons, body wall muscle, and vulval tissue. In the vulva, LIN-18::GFP was expressed in P5.p, P6.p, and P7.p and all their descendants throughout the L3 and L4 stages. In most (>90%) L4 stage individuals, descendants of P5.p and P7.p expressed higher levels of LIN-18::GFP than descendants of P6.p. No obvious difference in expression levels was found among different descendants of a single VPC (e.g., between P7.paa, P7.pap, P7.ppa, and P7.ppp).

• Primary Identifier: Expr15708
• Pattern: The translational LIN-12::GFP reporter was expressed on the apical membrane of the VPCs, while the LIN-18::GFP and PAT-3::GFP translational reporters localized predominantly to the basolateral compartment.

• Primary Identifier: Expr2013164
• Pattern: 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.
