WormMine: Gene WBGene00001396

• WormBase Gene ID: WBGene00001396
• Gene Name: fat-4
• Sequence Name: T13F2.1
• Brief Description: fat-4 encodes a delta-5 fatty acid desaturase; when expressed heterologously in S. cerevisiae, FAT-4 converts di-homo-gamma-linolenic acid (20:3delta8,11,14) to arachidonic acid (20:4delta5,8,11,14), an important precursor in eicosanoid metabolism, as well as on other fatty acids (C18 to C20); FAT-4 is is required in vivo for delta-5 unsaturated fatty acid synthesis.
• Organism: Caenorhabditis elegans
• Automated Description: Enables stearoyl-CoA 9-desaturase activity. Involved in unsaturated fatty acid biosynthetic process. Predicted to be located in membrane. Expressed in nerve ring and touch receptor neurons. Used to study alcohol use disorder. Is an ortholog of human FADS1 (fatty acid desaturase 1).

	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.

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.

	Maternal class (M): genes that are called present in at least one of the three PC6 replicates.	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_M
