  Genes regulated by DAF-12, 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.

  Transcripts that showed significantly increased expression in animals lacking P granules by RNAi experiments targeting pgl-1, pgl-3, glh-1 and glh-4, and unc-119-GFP(-), comparing to in control animals, at 2-day post L4 adult hermaphrodite stage. DESeq2, Benjamini-Hochberg multiple hypothesis corrected p-value < 0.05 and fold change > 2. WBPaper00050859:upregulated_P-granule(-)GFP(-)_vs_control_day2-adult
  Transcripts that showed significantly altered expression after 24 hour exposure to nitroguanidine (NQ). Multivariate permutation tests with random variance model implemented in BRB-Array Tools version 4.5 were performed to infer differentially expressed genes (DEGs). One thousand random permutations were computed per chemical class (i.e., a group of 16 arrays or samples). The confidence level of false discovery rate assessment was set at 80%, and the maximum allowed portion of false-positive genes was 10%. WBPaper00055899:nitroguanidine_regulated
  Transcripts that showed significantly increased expression in cfp-1(tm6369) comparing to in N2 at early embryo stage. DESeq2, FDR < 0.05 WBPaper00058691:cfp-1(tm6369)_upregulated
  Transcripts that showed significantly increased expression in set-2(tm1630) animals at embryo stage, comparing to in N2 animals. DESeq2 (v2.1.8.3) was used to determine DE genes and to generate principal component and scatter plots. DE genes with FDR < 0.05 were analysed using g:Profiler with Bonferroni correction. WBPaper00060014:set-2(tm1630)_upregulated
  Genes that showed expression levels higher than the corresponding reference sample (embryonic 24hr 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.

Differential expression analysis was performed in RStudio (v1.1.453) using R (v3.50) and Bioconductor (v3.7) packages. As outlined in the RNAseq123 vignette, data was imported, filtered and normalized using edgeR, and linear modeling and differential expression analysis was performed using limma. An FDR cutoff of <0.01 was used to define differentially expressed genes; no fold-change criteria was used. WBPaper00056034:pals-22(jy3)_upregulated
