WormMine: Gene WBGene00021237

• WormBase Gene ID: WBGene00021237
• Gene Name: crtc-1
• Sequence Name: Y20F4.2
• Brief Description: crtc-1 encodes a CREB-regulated transcriptional coactivator orthologous to mammalian CRTCs (OMIM: 608972); CRTC-1 is a central node linking the upstream lifespan modifiers AMPK and calcineurin to CREB activity via a shared signal-transduction pathway; posttranslational modification of CRTC-1 is required for their effects on longevity; CRTC-1 is both a critical and direct target of aak-2-mediated longevity; the longevity effects of inactivating crtc-1 are mediated by crh-1; crtc-1 is expressed throughout the intestine of the worm, as well as in head and tail neurons.
• Organism: Caenorhabditis elegans
• Automated Description: Enables cAMP response element binding protein binding activity. Involved in determination of adult lifespan. Located in cytosol and nucleus. Expressed in RICL; RICR; head neurons; intestine; and tail neurons. Is an ortholog of human CRTC1 (CREB regulated transcription coactivator 1).

	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.

	Genes regulated by DAF-16, according to whole transcriptome profiling to compare genome-wide regulatory influences of DPY-21 and SET-4 to those of the key transcription factors controlling dauer arrest in eak-7;akt-1 animals, DAF-16 and DAF-12.	Authors identified genes differentially expressed between wild-type and eak-7;akt-1 double mutant animals [fold change >= 1.5 and false discovery rate (FDR) < 0.05]. Authors then compared the transcriptomes of eak-7;akt-1 double mutants to those of eak-7;akt-1 animals harboring mutations in dpy-21, set-4, daf-16, or daf-12, and identified genes that are differentially expressed in the opposite direction as in wild-type relative to eak-7;akt-1. Annotated gene expression data output from CuffDiff v2.2.1 was read into R version 3.2.1 for six comparisons: eak-7;akt-1 compared to (1) wild-type, (2) daf-16(mu86);eak-7;akt-1, (3) daf-12;eak-7;akt-1, (4) set-4(n4600);eak-7;akt-1, (5) set-4(dp268);eak-7;akt-1, and (6) dpy-21;eak-7;akt-1. Authors filtered genes by the following criteria: (1) status = OK for wild-type vs. eak-7;akt-1, (2) fold change (FC) >= 1.5 or FC <= 1/1.5 for wild-type vs. eak-7;akt-1 and (3) FDR < 0.05 for at least two separate comparisons.
