cgc4489_hermaphrodite_enriched_neuronal_genes

Authors first used a Student t test to select only those genes that were significantly regulated using both the observed standard deviation (local SD) and the global standard deviation compiled from a large number of different DNA microarray experiments (global SD). Authors selected genes that are sex regulated above the 95% confidence level. hermaphrodite-enriched neuronal genes

WBPaper00032948:FedUp

For each average expression value, the larger of the model-based error and empirical error was reported. ANOVA and T-tests were also computed in Rosetta Resolver using the reported errors. Expression values, errors, and P-values corresponding to transcript detection, ANOVAs, and T-tests were exported from Rosetta Resolver and analyzed elsewhere. A large cluster of genes up-regulated during early larval development..

WBPaper00046024:sleep_upregulated_oscillating

Genes were counted as significantly up or down regulated for L3 sleep-like if the calculated false discovery rate (FDR) was equal or smaller then 5.0% and the fold change was > 2. p-values were obtained from the moderated t-statistic and corrected with the Benjamini-Hochberg method.Only genes consistently up or down regulated in both the L3 and L4 molt were selected to eliminate the effect of developmental progression. Authors reasoned that gene expression changes that would be biologically relevant would oscillate with substantial amplitude in phase with the molting cycle. They applied an arbitrary threshold and selected only those genes that oscillated with an amplitude of at least 50%. Genes that were upregulated during lethargus (sleep-like) stage with oscillating expression, according to microarray analysis comparing L3 lethargus to L4 large, and L4 lethargus to young adult.

WBPaper00037901:GLD-1_mRNA_targets

Authors calculated the mean IP enrichment from the two analyses and given a cutoff of three-fold, they identified 948 reproducibly enriched mRNAs (14.2%) from of a total of 6635 detected by the array. 948 reproductively enriched mRNAs that co-immunoprecipitate with GLD-1. To identify GLD-1 mRNA targets, authors performed immunoprecipitation (IP) of GLD-1, followed by microarray analysis of the co-IPed mRNAs (RIP-chip). Extracts from young adult transgenic worms expressing a rescuing FLAG and GFP-tagged GLD-1, hereafter referred to as tagged GLD-1, were subjected to IP in triplicate with anti-FLAG (aFLAG IP) or anti-MYC (aMYC IP) antibodies as controls. Comparison of aFLAG IP versus aMYC IP to input revealed a large population of GLD-1-associated transcripts. Authors additionally performed complementary aFLAG IPs upon worms expressing either tagged GLD-1(GGF IP) or non-tagged GLD-1(N2 IP). Comparing transcript 'IP-enrichment values' from both approaches revealed a correlation of 0.96, which indicated high reproducibility of GLD-1 association with specific mRNAs even on a quantitative level.
