WormMine: Gene WBGene00001451

• WormBase Gene ID: WBGene00001451
• Gene Name: flp-8
• Sequence Name: F31F6.4
• Brief Description: flp-8 encodes three copies of a FMRFamide-related short peptide neurotransmitter; although the FLP-8 peptide can increase pharyngeal action potential frequency, loss of FLP-8 function does not result in a mutant phenotype, suggesting that FLP-8 may function redundantly with other FMRFamide-like peptides in the nervous system; FLP-8 expression is detected in embryos and larval stages, but not in adults; FLP-8 is expressed in the sensory neurons ASEL/R, URXL/R, and PVM.
• Organism: Caenorhabditis elegans
• Automated Description: Involved in negative regulation of turning behavior involved in mating. Predicted to be located in extracellular region. Expressed in PVM; head; nerve ring; and tail.
• Biotype: SO:0001217
• Genetic Position: X :21.4805 ±0.007182
• Length (nt): 849

The resulting p-values were adjusted using the Benjamini and Hochbergs approach for controlling the false discovery rate (FDR). Transcripts with an adjusted p-value smaller 0.05 were assigned as differentially expressed.	WBPaper00044426:rotenone_24h_upregulated
	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.

• Primary Identifier: Expr2381
• Remark: Immunostaining increased in neuronal cell bodies of unc-104 KIF1A mutants, whereas staining in axons was proportionately diminished. In addition, a broader expression pattern was observed in unc-104 KIF1A mutants compared with wild-type controls, because retention in the cell bodies enabled identification of previously undetected neurons.

• Pattern: Nerve ring and other neuronal processes.
• Subcellular Localization: In wild-type animals, FaRPs immunostaining was most concentrated in the nerve ring and other neuronal processes, whereas neuronal cell bodies had lower levels of expression.
