WormMine: Gene WBGene00000085

• WormBase Gene ID: WBGene00000085
• Gene Name: aex-2
• Sequence Name: T14B1.2
• Brief Description: aex-2 encodes a G-protein-coupled receptor; aex-2 functions in the nervous system to activate a G(s) alpha (gsa-1) signaling pathway that regulates defecation in the hermaphrodite digestive tract; in regulating the defecation cycles, AEX-2 likely serves as the receptor for the NLP-40 neuropeptide secreted by the intestine; an AEX-2::GFP reporter fusion is expressed in the nerve ring, ventral nerve cord, the head mesodermal cell and enteric muscles; tissue-specific expression studies suggest that AEX-2 acts in GABAergic neurons, such as AVL and DVB, to control the expulsion, and possibly anterior body contraction, steps of defecation.
• Organism: Caenorhabditis elegans
• Automated Description: Predicted to enable neuropeptide receptor activity. Involved in several processes, including lipid transport involved in lipid storage; positive regulation of digestive system process; and positive regulation of triglyceride transport. Predicted to be located in cilium and plasma membrane. Expressed in alimentary muscle; head mesodermal cell; intestine; and nervous system.

	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

	Transcripts that showed significantly decreased expression in N2 animals exposed to 0.1mM Paraquat from hatching to reaching adult stage.	DESeq2 version 1.22.2, p < 0.05	WBPaper00064716:paraquat_downregulated
	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.
