WormMine: Gene WBGene00002975

• WormBase Gene ID: WBGene00002975
• Gene Name: lev-8
• Sequence Name: C35C5.5
• Brief Description: lev-8 encodes a novel nicotinic acetylcholine receptor (nAChR) alpha subunit that is a member of the ACR-8 group of nAChR subunits; LEV-8 activity is required for normal rates of pharyngeal pumping and for fully wild-type responses (increased egg laying and body wall muscle contraction) to the nAChR agonist and antihelmintic levamisole; expression of a LEV-8::GFP reporter construct begins at the L1 larval stage and is detected in neurons, body wall and uterine muscle cells, and socket cells of the IL and OL mechanosensory neurons; expression in body wall muscles is strongest in the anterior, consistent with increased levamisole resistance of head, or anterior, muscles seen in lev-8 mutant animals.
• Organism: Caenorhabditis elegans
• Automated Description: Predicted to enable acetylcholine-gated monoatomic cation-selective channel activity. Predicted to be involved in excitatory postsynaptic potential and monoatomic ion transmembrane transport. Predicted to be located in neuron projection; plasma membrane; and synapse. Predicted to be part of acetylcholine-gated channel complex. Expressed in several structures, including DD neuron; anal depressor muscle; ganglia; head neurons; and uterine-vulval cell. Human ortholog(s) of this gene implicated in congenital myasthenic syndrome 1A and congenital myasthenic syndrome 1B. Is an ortholog of human CHRNA1 (cholinergic receptor nicotinic alpha 1 subunit).

	Transcripts expressed in neuronal cells, by analyzingfluorescence-activated cell sorted (FACS) neurons.	DESeq. False discovry rate (FDR) < 0.1.	WBPaper00048988:neuron_expressed

	Genes that showed expression levels higher than the corresponding reference sample (embryonic 24hr 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.

	Genes with expression level regulated by genotype (N2 vs CB4856) 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_regulated_developing

	Genes that showed decreased expression after 1-methylnicotinamide (MNA) treatment.	Raw counts for the genes were analyzed using the R Statistical Computing Environment and the Bioconductor packages DESeq and edgeR. Both packages provide statistical routines for determining differential expression in digital gene expression data using a model based on the negative binomial distribution. The resulting p-values were adjusted using the Benjamini and Hochberg's approach for controlling the false discovery rate (FDR). If both FDR values (by DESeq and edgeR) were smaller than p = 0.05, genes were assigned as differentially expressed.	WBPaper00044260:1-methylnicotinamide_downregulated

• Primary Identifier: Expr3225
• Remark: Reporter gene fusion type not specified.
• Pattern: LEV-8 is first detected in L1 animals in a single pair of neurons in the head, approximately midway along the isthmus. It is also expressed in the PVT interneuron situated in the lumbar ganglion, at the rear of the animal. By L4, LEV-8 is expressed in all six DD motor neurons in the ventral nerve cord. As well as expression in several neuronal cell types, LEV-8 is expressed in body wall and in uterine muscles UV1 and UV2. Expression in the body wall was strongest anteriorly, which accords with the higher level of resistance exhibited by the head muscles of lev-8(x15) mutant worms. In the adult worm, LEV-8 is expressed in many neurons in the anterior nervous system. One of the more prominent of these is a single cell in the dorsal ganglion, ALA. LEV-8 is expressed in the IL and OL socket cells but not the neurons themselves.
