Candidate daf-19 down regulated genes with a statistically significant signal variation of 1.5-fold or greater. These were identified using a class comparisons tool from BRB Array Tools. |
BRB Array Tools (version 3.3) was subsequently used to identify genes with a statistically significant variation in expression when comparing between the two classes defined in this study. The probability threshold was set at a maximum of 0.05 (p-value <= 0.05) for genes to be considered statistically different. Genes with a signal variation of 1.5-fold or greater were selectively identified for use in all subsequent experiments. To reduce the chances of false discoveries, a class comparison test was conducted using a multivariate permutation test with the confidence level of 97%. |

Genes that showed significantly decreased expression in daf-19(m86);daf-12(sa204) comparing to in daf-12(sa204), at 3-fold embryo stage. |
BRB Array Tools were used to identify genes with statistically significant variation in expression. The probability threshold was set at a maximum of 0.05 (p-value <= 0.05) for genes to be considered statistically differentially expressed in wild-type and mutant populations. Genes with a signal variation of 1.5-fold or greater were selected for subsequent experiments. To reduce false discoveries, a class comparison test was conducted using a multivariate per mutation test with a confidence level of 97% (L1 analysis) and 90% (adults). |

Candidate daf-19 down regulated genes with a statistically significant signal variation of 1.5-fold or greater. These were identified using a Significance Analysis of Microarrays (SAM). |
Lists of genes were generated using SAM (version 2.2) with a false discovery rate (FDR) of less than or equal to 5% (Q-value <= 5%). Twenty-seven repeated runs of SAM were performed using variable random seed numbers for each run. During each run of SAM, 100 permutations were performed. Genes (n =129 downregulated, n = 1 upregulated) appearing in at least 80% of all twenty-seven runs of SAM were further considered for signal variation filtering, which was used to selectively identify genes with a 1.5-fold or greater variation between the two genetic conditions used for comparison. |
