:The Statistical Analysis for Microarrays (SAM) program was used to determine the statistically significant differences in gene expression. Merrell et al.(2002) used at least a twofold change (50% fold change) to determine these genes with statistical significant differences whereas we are using a 20% fold change. | :The Statistical Analysis for Microarrays (SAM) program was used to determine the statistically significant differences in gene expression.
