WBPaper00038168:lin-35_downregulated

For each gene in each microarray hybridization experiment, the ratio of RNA levels from the two samples was transformed into a log2 value and the mean log2 ratio was calculated. The log2 ratios were normalized by print-tip Loess normalization (Dudoit and Yang, 2002). All genes with a false discovery rate of <= 5% (q <= 0.05) (Storey and Tibshirani, 2003) and a mean fold-change ratio of >= 1.5 were selected for further analysis. Genes that were downregulated in lin-35.

All genes with a false discovery rate of <= 5% (q <= 0.05) (Storey and Tibshirani, 2003) and a mean fold-change ratio of >= 1.5 were selected for further analysis. Genes that were upregulated in lin-35.

All data were analyzed using Stat View J 5.0, with all experimental data checked for assumptions of homogeneity of variance across manipulations using Bartletts test. Once the assumptions were satisfied, the data were analyzed by one-way analysis of variance followed by Dunnetts multiple comparison test. When homogeneity was not evident in the data, we used the nonparametric KruskalWallis test, followed by the MannWhitney U-test with a Bonferroni adjustment. Differences were considered significant at P < 0.05. Genes suppressed following 24h exposure to lithium compounds (78uM LiCl and 375uM Li2CO3), according to custom DNA microarray.
