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. |

Coexpression clique No. 203, sre-33-ZK1025.1_8337, 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 with expression level regulated by genotype (N2 vs CB4856) and age at old adults stage (214 hours at 24 centigrade). |
For model 2, authors used 100 permutations to estimate the FDR threshold. Per permutation, genotypes and ages were independently randomly distributed, keeping the among-gene structure intact. Then for each spot (23,232) on the array, model 2 was tested. The obtained P-values were used to estimate a threshold for each of the explanatory factors. Authors also used a genome-wide threshold of -log10 P-value = 2, which resembles an FDR of 0.072 and 0.060 for marker and the interaction age-marker for the developing worms and FDR of 0.050 and 0.065 for marker and age-marker for the aging worms. For the physiological age effect, authors used a log10 P-value = 8 in developing worms (0.012 FDR) and -log10 P-value = 6 (0.032 FDR). |

Transcripts that showed significantly increased expression in set-2(zr2012) 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. |

Genes with differential expression under 0.5mg/l Chlorpyrifos (CPF) treatment at 24 centigrade. |
To identify the differentially expressed genes in each treatment authors used linear models per toxicant and temperature (gene expression = Toxicant (effect) + error). The lm function in R stats package was used to implement the linear models analysis with recommended default options. For threshold determination authors used a permutation approach. For each of the 23,232 permutations used authors randomly picked a transcript (array spot), which could only be picked once. Authors combined all the expression values of this transcript and randomly distributed them over the replicates and used them in the linear model. In this way authors obtained a threshold for each of the toxicants. Authors used a -log10 p-value 2 as common threshold for the analysis, which resembles to the following FDR per toxicant: 0.0155 for CPF at 24 centigrade, 0.0148 for DZN at 24 centigrade, 0.0168 for CPF+DZN at 24 centigrade, 0.0142 for CPF at 16 centigrade, 0.0151 for DZN at 16 centigrade, and 0.0148 for CPF+DZN, at 16 centigrade. |

Genes that showed decreased expression after 50uM TBBP treatment comparing with control. |
Differentially expressed genes (DEGs) were identified with a random variance t test and a significance analysis of microarrays (SAM) test. Genes were considered statistically significant if their p value was less than 0.05, the false discovery rate less than 0.3 and the fold change compared to control at least <= 0.67 or >= 1.5. |

Genes specifically expressed in germline when comparing RNAseq data of N2 to glp-4(bn2ts). |
Authors extracted all genes with more than 25 mapped reads and computed fold changes for all gene loci between wild type and mutants. The group of genes with 4-fold up-regulation in wild type was considered to be specifically expressed in the germline, while genes with 4-fold down-regulation in wild type where assumed to be specific to somatic cell lineages. |
