- Each entry in this table is the number of significant genes when comparing treatment (DMSO + drug) with control (just DMSO) for a cell type (embryoid blast or myeloid) and a time point (4 or 24 hours). All data were subject to quantile-quantile normalization and summarized using RMA. The Benjamini and Hochberg algorithm was used on P values generated by the standard t test, cyber t, and scheme 4 to calculate false discovery rate. The values for SAM were generated by the TIGR Multiple Array Viewer (see Materials and methods) with 100 permutations and the default parameters. DMSO, dimethyl sulfoxide; RMA, Robust Multichip Average; SAM, significance analysis of microarrays.
