WormBase Gene ID  ? WBGene00009218 Gene Name  acs-20
Sequence Name  ? F28D1.9 Brief Description  acs-20 encodes a protein homologous to the mammalian FATP1 and FATP4 fatty acid transport proteins (FATP)/very long chain fatty acid acyl-CoA synthetases; acs-20 activity is required for proper cuticle development, specifically formation of a cuticle surface barrier that prevents penetration of small molecules; acs-20 may affect cuticle development via its role in incorporation of very long chain fatty acids, but not other fatty acids, into sphingomyelin; acs-20; acs-22 doubly mutant animals have moresevere cuticle barrier defects than acs-20 single mutants, suggesting that the two genes function redundantly; acs-20 defects can be rescued by human Fatp4; an ACS-20::GFP fusion protein is expressed in the hyp7 and seam hypodermis, as well as the vulval and anal muscles; in hypodermal cells, ACS-20 localizes in a reticular pattern suggestive of localization to the endoplasmic reticulum.
Organism  Caenorhabditis elegans Automated Description  Predicted to enable long-chain fatty acid transmembrane transporter activity and long-chain fatty acid-CoA ligase activity. Predicted to be involved in long-chain fatty acid import into cell and long-chain fatty acid metabolic process. Located in intracellular membrane-bounded organelle. Expressed in anal depressor muscle; anal sphincter muscle; head; hyp7 syncytium; and seam cell. Human ortholog(s) of this gene implicated in obesity. Is an ortholog of human SLC27A1 (solute carrier family 27 member 1) and SLC27A4 (solute carrier family 27 member 4).

  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
Dietary restriction Transcripts that showed significantly decreased expression after N2 animals were under dietary restriction (DR, OP50 OD = 0.1) from 3-day post L4 till 6-day post L4 adult hermaphrodite stage, comparing to under ad libtum (AL, OP50 OD = 3) condition. Bioconductor package edgeR, p < 0.05. WBPaper00056443:DietaryRestriction_downregulated
  Strictly maternal class (SM): genes that are the subset of maternal genes that are not also classified as embryonic. 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_SM

  Top 300 transcripts enriched in excretory duct, excretory pore according to single cell RNAseq. Top 300 enriched transcripts were determined by log2.ratio of the tpm in the cell type vs the tpm in the other cells * the log2 of the cell.type tpm. WBPaper00061340:Excretory_duct_and_pore

  Proteins that showed significantly decreased expression after 1-day-old wild type adults were exposed to cisplatin (300ug per mL) for 6 hours. The differential expression analysis was performed in R. Differentially expressed proteins were identified by using a two-sided t-test on log-transformed data. WBPaper00065373:Cisplatin_downregulated_WT
  Genes that showed oscillating mRNA expression level throughout the 16 hour time courses from L3 larva to young adult. The following three lines of R code were used to perform the classification: increasing <-2*amplitude-PC1 < -1.7; oscillating <-!increasing & (amplitude > 0.55); flat <-!increasing & !oscillating; Note that the amplitude of a sinusoidal wave corresponds to only half the fold change between trough and peak. WBPaper00044736:oscillating_dev_expression
  Transcripts that showed significantly increased expression in hpk-1(pk1393) comparing to in N2 at adult day 2. DESeq 2, fold change > 2, FDR < 0.05. WBPaper00065581:hpk-1(pk1393)_upregulated
  Transcripts that showed significantly increased expression in hda-1(ne4752[3xFLAG-Degron-HDA-1]) in gonads dissected from 1-day old adult animals. Salmon was used to map the mRNA-seq reads with the worm database WS268, and its output files were imported to DESeq2 in R. The differentially expressed genes were filtered by fold change more than 2 and adjusted p-value < 0.05. The scatter plots were generated by the plot function in R. WBPaper00061479:hda-1(ne4752)_upregulated
  Genes that showed expression levels higher than the corresponding reference sample (embryonic 0hr 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.
