WormMine: Gene WBGene00003167

• WormBase Gene ID: WBGene00003167
• Gene Name: mec-3
• Sequence Name: F01D4.6
• Brief Description: mec-3 encodes a founding member of the LIM (Lin-11, Isl-1, Mec-3) homeodomain family of transcriptional regulators; during C. elegans development, MEC-3 activity is required for proper differentiation and maturation of the mechanosensory neurons; MEC-3 is expressed in the mechanosensory neurons, where initiation of expression is dependent upon the UNC-86 homeodomain protein and maintenance of expression is dependent upon MEC-3 itself and mec-17.
• Organism: Caenorhabditis elegans
• Automated Description: Enables several functions, including DNA-binding transcription factor activity, RNA polymerase II-specific; RNA polymerase II transcription regulatory region sequence-specific DNA binding activity; and transcription coactivator activity. Involved in several processes, including mechanosensory behavior; neuron projection organization; and positive regulation of transcription by RNA polymerase II. Part of RNA polymerase II transcription regulator complex. Expressed in VA neuron; touch receptor neurons; ventral nerve cord; and vulva. Is an ortholog of human LHX1 (LIM homeobox 1) and LHX5 (LIM homeobox 5).

	Transcripts that showed significantly increased expression in L1 neural cells comparing to in adult neural cells.	DESeq2 (v1.18.1) fold change > 2, P-adj<0.05, using BenjaminiHochberg correction.	WBPaper00060811:L1_vs_adult_upregulated_neural
	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.

Bacteria infection: Enterococcus faecalis	Genes with increased expression after 24 hours of infection by E.faecalis 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.

	Transcripts expressed in NMDA neuron, according to PAT-Seq analysis using Pnmr-1-GFP-3XFLAG mRNA tagging.	Cufflinks FPKM value >=1.	WBPaper00050990:NMDA-neuron_expressed
	Genes with expression level regulated by genotype (N2 vs CB4856) and age 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_age_regulated_developing
