WormMine: Gene WBGene00019376

• WormBase Gene ID: WBGene00019376
• Gene Name: lipl-4
• Sequence Name: K04A8.5
• Brief Description: lipl-4 encodes a triglyceride lipase; by homology, LIPL-4 is predicted to function in lipid hydrolysis; genetic studies indicate that lipl-4 functions as part of an endocrine signaling pathway that coordinates reproductive status, fat metabolism, and longevity; in response to reduced insulin signaling or germline removal (glp-1 mutant animals), lipl-4 expression is induced in the intestine, in a DAF-16-dependent manner; overexpression of lipl-4 can extend lifespan, in a manner dependent upon autophagy genes, such as bec-1, vps-34, and lgg-1.
• Organism: Caenorhabditis elegans
• Automated Description: Enables triglyceride lipase activity. Involved in cellular lipid metabolic process; determination of adult lifespan; and positive regulation of macroautophagy. Located in lysosome. Expressed in intestine and seam cell. Human ortholog(s) of this gene implicated in Wolman disease; autosomal recessive congenital ichthyosis 8; and cholesterol ester storage disease. Is an ortholog of several human genes including LIPA (lipase A, lysosomal acid type); LIPF (lipase F, gastric type); and LIPJ (lipase family member J).

	Genes that showed significantly increased expression in daf-2(e1370) comparing to in N2.	To identify DEGs, Students t test and the log2 median ratio test were performed to compute t values and median ratios for all the annotated genes. The adjusted P values from each test were computed using an empirical distribution of the null hypothesis, which was obtained from random permutations of the samples. Finally, the adjusted P values from the individual tests were combined to compute the overall P values using Stouffers method , and genes with overall P < 0.05 and fold change > 1.5 were selected as DEGs.

	Expression Pattern Group C, enriched for genes involved in metabolic processes.	The significance (P 0.0001) of the relative age (time) was used to determine if a gene was differentially expressed between the three age (time) groups. The effect of this factor explaining gene expression differences was used to determine if the expression went up or down during the two age/time periods (t1 - t2 and t2 -t3). Authors used a permutation approach to determine the thresholds for the different mapping strategies. For each of the used models for eQTL mapping, authors used 23,000 permutations. For each permutation, authors randomly picked a spot; each spot could only be picked once. The gene expression and relative lifespan values were than randomly distributed over the RILs (and time points) and used for mapping. In this way, authors obtained a threshold for each of the explaining factors. For the single time points, authors used a FDR of 0.01 to adjust for multiple testing. The genome-wide threshold for this FDR is -log10 P = 3.8 for each of the three time points. For the combined models (t1 to t2 and t2 to t3), authors used a genome-wide threshold of -log10 P = 4, which resembles an FDR of 0.006, 0.001, and 0.006 for marker, age, and the interaction between marker and age, respectively. To determine the threshold for the single gene examples, authors used 1000 permutations as in the genome-wide threshold. The difference is that they use the gene under study in all of the permutations. The P-values for the gene specific thresholds were determined at FDR = 0.05.	WBPaper00036286:Pattern_C
