WBPaper00031903:prg-1_regulated

The fold differences from the three experiments were averaged, and a Z test [Z = (observed - expected) / SE] was performed. Genes with up- or downregulation greater than 1.5-fold, p < 0.05, in any given mutant were selected for inclusion. Genes with differential expression in prg-1(tm872) male gonads comparing to N2.

WBPaper00027758:Group_I

For each set of mutant data, the repeats were averaged, and a Z test [Z=(observedexpected)\/SE] was performed in Excel. A moderate correction for multiple testing (~17,600 genes) was performed by multiplying the calculated P-value by 10,000. After this correction, all genes with up- or downregulation greater than twofold, P<0.05 in any given mutant were selected. The hypergeometric probability test was used to calculate the significance of overlap of gene groups. Authors determined whether transcripts of Group I-IV genes are bound by GLD-1, based on a minimum criteria of >1.5 enrichment in GLD-1 immunoprecipitated samples compared to control immunoprecipitations (P < 0.01). Genes downregulated in dpl-1(n3316) and efl-1(n3639) mutants.

[cgc5767]:expression_class_SE

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. Strictly embryonic class (SE): genes that are the subset of embryonic genes that are not also classified as maternal.

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. Strictly embryonic (SE) subclasses are based on the earliest significant increase(abbreviated pi for primary increase).

Genes with higher expression in one or more mutants of efl-1, dpl-1 and lin-35 relative to controls.
