WormMine: Gene WBGene00015981

• WormBase Gene ID: WBGene00015981
• Gene Name: elt-7
• Sequence Name: C18G1.2
• Brief Description: elt-7 encodes a GATA-type transcription factor; during embryonic development, ELT-7 functions together with ELT-2 in the endoderm/gut to regulate the transition from cell fate specification to differentiation; expression of ELT-7 is sufficient to induce gut-specific differentiation; an elt-7::gfp promoter fusion is expressed in the gut lineage beginning at the 2E-cell stage of gut development and continuing through adulthood; elt-7 expression is initiated through the combined action of the END-1 and END-3 transcription factors.
• Organism: Caenorhabditis elegans
• Automated Description: Predicted to enable DNA-binding transcription factor activity, RNA polymerase II-specific and RNA polymerase II cis-regulatory region sequence-specific DNA binding activity. Involved in endodermal cell fate determination. Located in nucleus. Expressed in E lineage cell.

	Genes that were downregulated in lin-15B(n744).	For each gene in each microarray hybridization experiment, the ratio of RNA levels from the two samples was transformed into a log2 value and the mean log2 ratio was calculated. The log2 ratios were normalized by print-tip Loess normalization (Dudoit and Yang, 2002). All genes with a false discovery rate of <= 5% (q <= 0.05) (Storey and Tibshirani, 2003) and a mean fold-change ratio of >= 1.5 were selected for further analysis.

	Transcripts that showed significantly altered expression after 24 hour exposure to nitroguanidine (NQ).	Multivariate permutation tests with random variance model implemented in BRB-Array Tools version 4.5 were performed to infer differentially expressed genes (DEGs). One thousand random permutations were computed per chemical class (i.e., a group of 16 arrays or samples). The confidence level of false discovery rate assessment was set at 80%, and the maximum allowed portion of false-positive genes was 10%.	WBPaper00055899:nitroguanidine_regulated
Bacteria infection: Serratia marcescens	Genes with increased expression after 24 hours of infection by S.marcescens Fold changes shown are pathogen vs OP50.	For RNA-seq and tiling arrays, log2 fold changes between gene expression values of infected versus uninfected nematodes were calculated. For log2 fold changes > 0.00001 the values > 81.25th percentile were defined as up-regulated and for log2 fold changes < -0.00001 the values < 18.75th percentile were defined as down-regulated.

	Genes expressed in N2.	Expressed transcripts were identified on the basis of a Present call in 3 out of 4 N2 experiments as determined by Affymetrix MAS 5.0.	WBPaper00025141:N2_Expressed_Genes
	Genes uniquely expressed in endoderm, according to RNAseq studies on blastomere (with isolated AB, MS, E, C, D founder cells dividing in vitro) time course and whole embryo time course.	Germ layers were assigned by correlating the average expression with germ-layer-specific patterns with a cutoff of 0.6 correlation with the following idealized vectors: endoderm = [00100]; ectoderm = [10000]; mesoderm = [01011], where the order is AB, MS, E, C and P3. Germ-layer genes were defined according to the sum of the genes identified by the clusters and are indicated in Fig. 2b. Authors further filtered the germ-layer gene sets by keeping only those genes whose expression was partitioned across the germ layers such that at least two-thirds of the expression was in that germ layer.	WBPaper00046121:endoderm_unique
	Transcripts that showed significantly increased expression in day 3 adult hermaphrodite comparing to in L4 larva daf-16(mu86);glp-1(e2141) animals.	Fold change > 2, FDR < 0.05	WBPaper00064088:Day-3-adult_vs_L4_upregulated_daf-16(mu86);glp-1(e2141)
	Transcripts enriched in intestine by comparing dissected germline tissue with dissected intestine tissue, both injected with empty RNAi vector.	Genes were determined intestine-enriched if the lowest expression value (log2(FPKM+1)) observed in the intestine empty vector samples was at least 2-fold higher than the highest expression value observed in the germline empty vector samples.	WBPaper00051039:intestine_enriched
	Embryonic class (E): genes that significantly increase in abundance at some point during embryogenesis.	A modified Welch F statistic was used for ANOVA. For each gene, regressed error estimates were substituted for observed error estimates. The substitution is justified by the lack of consistency among the most and least variable genes at each time point. Regressed error estimates were abundance-dependent pooled error estimates that represented a median error estimate from a window of genes of similar abundance to the gene of interest. A randomization test was used to compute the probability Pg of the observed F statistic for gene g under the null hypothesis that developmental time had no effect on expression. P-values were not corrected for multiple testing.	[cgc5767]:expression_class_E

• Pattern: Inferred expression. EPIC dataset. http://epic.gs.washington.edu/ Large-scale cellular resolution compendium of gene expression dynamics throughout development. This reporter was inferred to be expressing in this cell or one of its embryonic progenitor cells as described below. To generate a compact description of which cells express a particular reporter irrespective of time, the authors defined a metric "peak expression" for each of the 671 terminal ("leaf") cells born during embryogenesis. For each of these cells, the peak expression is the maximal reporter intensity observed in that cell or any of its ancestors; this has the effect of transposing earlier expression forward in time to the terminal set of cells. This metric allows straightforward comparisons of genes' cellular and lineal expression overlap, even when the expression occurs with different timing and despite differences in the precise time point that curation ended in different movies, at the cost of ignoring the temporal dynamics of expression, a topic that requires separate treatment. For simplicity, the authors use the term "expressing cells" to mean the number of leaf cells (of 671) with peak expression greater than background (2000 intensity units) and at least 10% of the maximum expression in that embryo. Quantitative expression data for all cells are located here: ftp://caltech.wormbase.org/pub/wormbase/datasets-published/murray2012/
