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. |

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. |

mRNAs that were significantly enriched in the AIN-1 immunoprecipitation samples, compared to the control total mRNAs in the input extracts (p < 0.01). |
Signals from replicates of total worm lysates from wt and strains containing the ain-2::gfp or the ain-2 promoter::gfp transgene were mean normalized and averaged respectively to generate standard profiles of gene expression in these worm strains. Authors then calculated the ratio of signal of each gene from each IP sample to the standard gene expression profile of the corresponding worm strain. Based on this ratio, a percentile rank of each gene relative to all genes in each IP replicate was calculated. The percentile ranks in the three replicates of each IP were averaged. Student t test was utilized to determine if the average percentile ranks of enrichment of individual genes were significantly higher (p value) than the mean enrichment of all genes in the IP samples. To determine the AIN-1 or AIN-2 associated genes, we used the following criteria: (1) average percentile ranks of enrichment is greater than the mean enrichment of all genes in AIN-1 or AIN-2 IP with p < 0.01; (2) average signal in AIN-1 or AIN-2 IP replicates is greater than the background signal (including 2X standard deviation (SD)) (Background signal and SD were calculated based on signals from empty spots on each microarray); (3) criteria 1 is not be satisfied for the same gene in the corresponding control IP. |

Potental DAF-12 target genes identified by ChIP-chip analysis performed on strain ALF4 [daf-12 |
Affymetrix TAS software that computed for each probe estimates of fold enrichment (in linear scale) over hybridization with input DNA. At the same time, TAS calculated for each probe a p-value by applying a Wilcoxon signed rank test. A threshold of 2.5 was selected, which corresponds to probe intensities approximately 2.5 times stronger on the ChIP array than on the Input array. Additional TAS threshold parameters were MinRun=180 bp, MaxGap=300 bp. TAS analysis showed that the selected threshold of 2.5 corresponds approximately to a p-value of 0.01. |

Coexpression clique No. 211, srj-42-srw-113, on the genome-wide coexpression clique map for the nematode GPL200 platform. |
All available microarray datasets for the GPL200 platform (Affymetrix C. elegans Genome Array) were obtained from the GEO repository. This included 2243 individual microarray experiments. These were normalized against each other with the software RMAexpress (Bolstad, 2014). Based on these normalized values, Pearsons correlation coefficients were obtained for each probe-probe pair of the 22,620 probes represented on this array type. The resulting list of correlation coefficients was then ranked to generate the ranked coexpression database with information on each probe represented on the GPL200 platform. |

Genes from N2 animals with significantly decreased expression after 72 hours of treatment on growth media with 10uM rapamycin in 2% DMSO. |
Analysis of gene expression data was carried out with the Affymetrix Transcriptome Analysis Console. Data preprocessing (using RMA normalization) and QC metrics were performed using Affymetrix Expression Console TM and manually inspected afterwards. Expression analysis was carried out for each two pairwise conditions. FDR statistical correction for multiple testing resulted in a slightly lower number of DEGs in most cases. P-value < 0.05 and fold change > 2.0 were used to determine differentially expressed genes. |
