WormMine: Gene WBGene00000096

• WormBase Gene ID: WBGene00000096
• Gene Name: ahr-1
• Sequence Name: C41G7.5
• Brief Description: ahr-1 encodes an aryl hydrocarbon receptor (ligand-activated basic helix-loop-helix transcription factor) ortholog that biochemically resembles its vertebrate relatives (OMIM:600253) which mediate the carcinogenic and teratogenic effects of environmental toxins; AHR-1 activity is required for specification of RMEL and RMER GABAergic neuron cell fate and negative regulation of spontaneous movement; AHR-1 binds HSP90 tightly, and forms a dimer with AHA-1 that binds DNA fragments containing the mammalian xenobiotic response element; AHR-1 is expressed in neurons.
• Organism: Caenorhabditis elegans
• Automated Description: Enables DNA binding activity and RNA polymerase II-specific DNA-binding transcription factor binding activity. Involved in negative regulation of locomotion and response to xenobiotic stimulus. Predicted to be located in nucleus. Predicted to be part of nuclear aryl hydrocarbon receptor complex. Expressed in ALML; ALMR; RMEL; RMER; and neurons. Human ortholog(s) of this gene implicated in pancreatic cancer and retinitis pigmentosa 85. Is an ortholog of human AHR (aryl hydrocarbon receptor).

	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 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

• Primary Identifier: Expr2009271
• 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. Interactive visualizations are available as a web app (https://cello.shinyapps.io/celegans/) and can also be installed as an R package (https://github.com/qinzhu/VisCello.celegans).

• Primary Identifier: Expr1030046
• Pattern: Tiling arrays expression graphs

• Primary Identifier: Expr2937
• Pattern: Both ahr-1:GFP reporters are expressed during embryonic and larval development. Expression is first detected in two cells 260 min after the first cleavage. By midembryogenesis (pre-comma stage), 14 cells express the pJ360 ahr-1:GFP fusion gene. At the 2-fold stage of embryogenesis, two cells express ahr-1:GFP in the tail, and the remaining fluorescing cells are in the forming head. During the first larval stage. ahr-1:GFP is expressed in 28 neurons, several blast cells, and two phasmid socket cells. The neurons that express ahr-1:GFP include ALNR/ALNL, AQR/PQR, AVM/PVM, BDUR/BDUL, PLMR/PLML, PLNR/PLNL, PHCL/PHCR, PVWL/PVWR, RMEL/RMER, SDQR/SDQL, and URXR/URXL. The T.pa, T.ppa, and T.ppp blast cells in the tail express ahr-1:GFP, as do all of their descendents, including the PHso1 and PHso2 phasmid socket cells. ahr-1:GFP is also expressed in the MI and I3 neurons in the pharynx and the G2 and W blast cells. Four additional cells in the head express ahr-1:GFP, tentatively identified as the ASK and RIP neurons.
• Subcellular Localization: The pJ360 construct includes the entire ahr-1 genomic sequence, and transgenic animals express this fusion protein in a subset of neuronal nuclei. The pHT102 transgene lacks most of the ahr-1 coding sequence and labels axons as well as nuclei.

• Primary Identifier: Expr2855
• Remark: Reporter gene fusion type not specified.
• Pattern: This transgene was expressed in many neurons. Pahr-1 GFP was expressed in RMEL and RMER, but not in RMED and RMEV, cells.

• Primary Identifier: Expr7905
• Remark: Picture: Figure 2. Reporter gene fusion type not specified.
• Pattern: Expressed in less than 10 neurons but not ASE.

• Primary Identifier: Expr13952
• Pattern: ahr-1 is expressed in all six TRN.

• Primary Identifier: Expr2027508
