WormMine: Gene WBGene00013746

• WormBase Gene ID: WBGene00013746
• Gene Name: lgc-55
• Sequence Name: Y113G7A.5
• Brief Description: lgc-55 encodes an amine-gated chloride channel; LGC-55 activity is required for backward locomotion and suppression of lateral head oscillations in response to anterior touch; LGC-55 is expressed in neurons and muscles that receive synaptic input from tyraminergic neurons, and localizes to the neuronal cell body and regions suggestive of postsynaptic specializations; when expressed in Xenopus oocytes, LGC-55 can be activated by both Beta-phenylethylamine as well as amphetamine, although the former acts more efficiently; additionally, amphetamine can potentiate the effects of Beta-phentylethylamine on LGC-55.
• Organism: Caenorhabditis elegans
• Automated Description: Enables chloride channel activity. Involved in chloride transport and mechanosensory behavior. Located in neuronal cell body and postsynaptic density. Expressed in GLR; egg-laying apparatus; head muscle; nerve ring; and neurons.

	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.
