WormMine: Gene WBGene00018304

• WormBase Gene ID: WBGene00018304
• Gene Name: agr-1
• Sequence Name: F41G3.12
• Brief Description: agr-1 encodes a large (1396-residue) putative agrin, orthologous to human AGRIN (OMIM:103320), EGFLAM, and Q9NQ15; AGR-1 is expressed in buccal epithelium and deposited in pharyngeal basal epithelium; AGR-1 is also expressed in IL1 neurons, distal tip cells, and intestine; an AGR-1 fragment can cluster vertebrate dystroglycan in cell culture; agr-1(eg1770) mutations show no obvious phenotype, including levimasole resistance, and do not enhance other mutations perturbing acetylcholine signalling, the dystrophin-glycoprotein-complex, muscle cell differentiation, or the extracellular matrix.
• Organism: Caenorhabditis elegans
• Automated Description: Enables dystroglycan binding activity. Located in basement membrane. Expressed in hermaphrodite distal tip cell; hyp7 syncytium; motor neurons; and pharynx. Human ortholog(s) of this gene implicated in congenital myasthenic syndrome 8. Is an ortholog of human AGRN (agrin).

In the pooled data set, 1453 C. elegans proteins were identified with a probability >= 0.9 according to ProteinProphet, of which 1165 proteins were identified by more than one unique peptide.

	Transcripts of coding genes that showed significantly decreased expression in muscle.	DESeq2 (version 1.24.0). Transcripts with a false-discovery rate adjusted p-value less than 0.05 were considered significantly differentially expressed.	WBPaper00062325:muscle_depleted_coding-RNA
	Transcripts expressed in neuronal cells, by analyzingfluorescence-activated cell sorted (FACS) neurons.	DESeq. False discovry rate (FDR) < 0.1.	WBPaper00048988:neuron_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. 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.

	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 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 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).

10 Expression Patterns

• Primary Identifier: Expr4838
• Remark: Picture: Figure 8 C and D.
• Pattern: The major site of agrin expression was around the pharynx and the staining was particularly enriched in the anterior part. The posterior bulb was labeled more weakly correlating with the fainter GFP reporter expression in the posterior part. Polyclonal antiserum staining resulted in the same staining pattern in wild type worms of different developmental stages. Young larvae (L1) generally showed stronger agrin staining compared to young adults. In addition to the pharynx staining in the wild type worms, the polyclonal antiserum stained the gut lumen both in the wild type worms as well as in the agrin mutants, but not when preimmune serum was used. The staining of the lumen of the gut represents an unrelated cross-reactivity of the antiserum, possibly corresponding to the background bands detected on the western blots.
• Subcellular Localization: Agrin was detected in the basal lamina around the pharynx procorpus and anterior bulb. Posterior bulb staining was weaker possibly due to poor antibody penetration.

• Primary Identifier: Expr4837
• Remark: Picture: Figure 5.
• Pattern: Fluorescence started to be visible in two cells of young embryos at around the 64 AB cell stage. Towards the end of gastrulation expression was visible in about 40 cells throughout the embryo including neuronal precursors, ventral hypodermal cells, and pharyngeal precursor cells. At the 1 to 2 fold stages fluorescence was observed in IL1 neurons (the identity was determined post-embryonically), the nine buccal epidermal cells, and additional cells in the head, most likely arcade cells. Transient expression was also observed in embryonic motoneurons (no longer visible in 3 fold stage embryos) and in a few apoptotic cells in the head. Based on their position they could be the sister cells of some of the IL1 neurons, which are known to undergo programmed cell death at this developmental stage. At the 3 fold stage expression was restricted to the buccal epidermal cells, most of the arcade cells (3 anterior and the DL and DR posterior arcade cells), and the six IL1 neurons. The two lateral IL1 neurons expressed the marker only weakly also in the L1 larval stage (but not later during development), whereas the dorsal and ventral IL1 neurons expressed GFP strongly throughout all larval stages and in the adults. Starting from the L1 larval stage expression could also be observed in the posterior cells of the gut. Starting from the L2 stage, when gonad development and migration begins, fluorescence became also visible in the distal tip cells of the gonad.
