WormMine: Gene WBGene00000238

• WormBase Gene ID: WBGene00000238
• Gene Name: bar-1
• Sequence Name: C54D1.6
• Brief Description: bar-1 encodes a beta-catenin; during C. elegans development, BAR-1 likely functions as a transcriptional coactivator whose activity is required for Q neuroblast migration, P12 cell fate specification, and P3.p through P8.p vulval cell fate specification at two different stages of development; in specifying vulval cell fates, bar-1 interacts with Wnt and MAPK signaling pathways to regulate proper expression of the LIN-39 homeodomain transcription factor, overexpresion of which can partially rescue the bar-1 mutant phenotype; in yeast two-hybrid assays, BAR-1 interacts strongly with the POP-1/TCF transcription factor, and when fused to the Gal4 DNA binding domain, BAR-1 can function in yeast as a transcriptional coactivator; during larval development, BAR-1 expression begins in P3.p through P8.p at the late L1 stage and then disappears from these cells by the mid-L3 stage; BAR-1 is also expressed in P12, in the seam cells, and in cells of the somatic gonad; BAR-1 subcellular localization, assessed using an integrated transgene, reveals localization to the cytoplasm, nucleus, and cell junctions; genetic mosaic analyses indicate that, in P4.p and in P12, bar-1 acts cell autonomously to specify cell fates.
• Organism: Caenorhabditis elegans
• Automated Description: Enables RNA polymerase II-specific DNA-binding transcription factor binding activity and transcription coactivator activity. Involved in several processes, including nematode larval development; reproductive behavior; and response to stress. Located in several cellular components, including adherens junction; cytosol; and nucleus. Expressed in several structures, including gonad; intestine; and vulva.

	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.

14 Expression Patterns

• Primary Identifier: Expr2009530
• 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.

• Primary Identifier: Expr1030152
• Pattern: Tiling arrays expression graphs

• Primary Identifier: Expr12634
• Pattern: A BAR-1::GFP translational fusion is faintly expressed throughout the body, with highest expression in the posterior gut, consistent with reports that egl-5 also is expressed and functions in the posterior end.

• Primary Identifier: Expr1395
• Pattern: Similar expression patterns were obtained using either the BAR-1 antibodies in immunocytochemistry experiments or by direct observation of the functional BAR-1-GFP. BAR-1 is present in P3.p through P8.p in the late L1/early L2 stage and disappears in the mid-L3 stage before the first divisions of P3.p-P8.p. Did not observe BAR-1 in P1.p, P2.p, P9.p, P10.p or P11.p at this time. P6.p occasionally showed higher BAR-1 expression than the other vulval precursor cells, and was often observed to be the last vulval precursor cell to lose BAR-1 staining. In addition to the vulval precursor cells, BAR-1 is expressed in several other postembryonic cells, including the seam cells , cells in the somatic gonad and P12.
• Subcellular Localization: In the vulval precursor cells, BAR-1 is predominantly cytoplasmic, with some protein present in the nucleus and some at cell junctions.

• Primary Identifier: Expr3089
• Pattern: GFP expression was seen in hypodermal seam cells. This expression began in the mid-L1 stage and was present in all larval stages and the adult. GFP expression was seen in sheath cells of the somatic gonad. Expression was also seen in a subset of ventral cord neurons (VCNs) and in the anchor cell of the gonad that was not previously observed with antibody staining or a BAR-1 translational GFP reporter. Expression is seen in 7 to 15 neurons between the posterior bulb of the pharynx and the anus in L1 animals 1 h after hatching, indicating that some embryonically derived neurons in the ventral cord are expressing bar-1. During the rest of the L1 and L2 stages, the number of GFP-expressing neurons increases to 20 40 per animal. By the L4 stage, the number of ventral cord neurons showing GFP expression anterior to the vulva is 0 9, and posterior to the vulva is 11 24. In regard to vulval development, GFP expression from the transcriptional fusion was first seen in Pn.p cells after their birth in the L1 stage. This expression persisted in the L2 and L3 stages and continued throughout the divisions of the VPCs until the early L4 stage. In the adult, strong GFP expression is confined to the vulval muscles, but faint expression is still seen in adult vulval cells.

• Primary Identifier: Expr12877
• Pattern: An 11-kb regulatory region upstream of the bar-1/b-catenin gene fused to GFP is not expressed in cloacal cells or in the trailing gonad but is strongly expressed in the linker cell.

• Primary Identifier: Expr1021743
• Pattern: Developmental gene expression time-course. Raw data can be downloaded from ftp://caltech.wormbase.org/pub/wormbase/datasets-published/levin2012

• Primary Identifier: Expr2027767

• Primary Identifier: Expr12041
• Pattern: BAR-1-GFP expression first appeared in P11.p in the late L1 stage. In the early-to-middle L2 stage, BAR-1-GFP accumulated in the cytoplasm of P11.p in a punctate pattern, presumably resulting from the stabilization of BAR-1 in response to increased Wnt signaling. The punctate GFP fluorescence in the cytoplasm of P11. p rapidly decreased during the mid-to-late L2 stage. By the mid-L3 stage, just before P11.p divides, BAR-1-GFP expression appeared to be brighter in the nucleus than in the cytoplasm. The switch of cytoplasmic-to-nuclear BAR-1-GFP accumulation is initiated in the mid-to-late L2 stage, coincident with the time window critical for the specification of HCG cell fates. BAR-1-GFP expression was undetectable in P10.p prior to cell division but became visible in the nucleus of the posterior daughter, P10.pp, suggesting that Wnt signaling through BAR-1 likely acts during fate execution of some descendants of the P10.p lineage. Although we did not observe lin-17::GFP expression in P9.p, faint, mostly cytoplasmic expression of BAR-1-GFP was sometimes seen in P9.p up to the mid-L2 stage, just before P9.p fuses with hyp7.

• Pattern: BAR-1-GFP expression first appeared in P11.p in the late L1 stage. In the early-to-middle L2 stage, BAR-1-GFP accumulated in the cytoplasm of P11.p in a punctate pattern, presumably resulting from the stabilization of BAR-1 in response to increased Wnt signaling. The punctate GFP fluorescence in the cytoplasm of P11. p rapidly decreased during the mid-to-late L2 stage. By the mid-L3 stage, just before P11.p divides, BAR-1-GFP expression appeared to be brighter in the nucleus than in the cytoplasm. The switch of cytoplasmic-to-nuclear BAR-1-GFP accumulation is initiated in the mid-to-late L2 stage, coincident with the time window critical for the specification of HCG cell fates. BAR-1-GFP expression was undetectable in P10.p prior to cell division but became visible in the nucleus of the posterior daughter, P10.pp, suggesting that Wnt signaling through BAR-1 likely acts during fate execution of some descendants of the P10.p lineage. Although we did not observe lin-17::GFP expression in P9.p, faint, mostly cytoplasmic expression of BAR-1-GFP was sometimes seen in P9.p up to the mid-L2 stage, just before P9.p fuses with hyp7.

	Genes that showed increased expression in bar-1(ga80) animal comparing to in N2.	All statistical analyses were performed using the statistical programming language R (version 2.13.1 x 64). A linear model was used to determine the effect and significance of the genotype on the expression levels (probe intensity + genotype + error). Using permutations of the original data in the same linear model, authors determined thresholds adjusted for multiple testing (FDR 0.05: -log10(p) > 2; FDR 0.01: -log10(p) > 3). To correct for the developmental difference between bar-1(ga80) and N2 authors used the developmental gene expression data from Snoek et al. (2014) together with the gene expression data generated for this study (bar-1(ga80) vs. N2) in one linear model (probe intensity, sample age + genotype + error). The intensities were corrected for batch effect and for sample age authors used an age of 44 hours for the bar-1(ga80) samples (as estimated), and 48 hours for the N2 samples.

	Genes that were considered as putative WNT pathway targets because they have higher expression in WNT overactivated (by delNTbar-1 overexpression in huIs10) animals comparing to in N2.	Genes that were considered as putative WNT pathway targets based on the following criteria. (1) an average fold change of 1.5-fold or more in deIs10; huIs1 (Wnt pathway overactivation) compared to control (N2); (2) present and increased calls in at least two of three biological replicates; (3) ANOVA P <=0.05; and (4) ratio of average fold change >= 1.5-fold between Wnt pathway overactivated (deIs10; huIs1) and underactivated (deIs10; deIs26) conditions.	WBPaper00046887:WNT-target
	Genes showing a statistically-significant decrease in gene expression of 2 fold or greater in response to expre ssion of delNTBAR-1 protein.	Criteria used for selection of BAR-1 responsive gene targets were (1) at least a twofold change in signal response to (del)NTBAR-1 overexpression compared with control average, (2) concurrence in directional change for at least two of the three (del)NTBAR-1 induced replicates (e.g., increase or decrease of signal), and (3) an analysis of variance p-value of <=0.05.	WBPaper00044857:BAR-1_downregulated
	Transcripts that showed significantly increased expression in Q neuroblast descendant cells expressing a constitutively active, N terminally truncated form of BAR-1 (beta-catenin) (del-N-BAR-1 Q) (huIs179).	Differential gene expression analysis was done with DESeq2 R-package using an FDR based on adjusted P < 0.05. (The threshold was reset from FDR < 0.1 to FDR < 0.05 by WormBase curator.)
