  1. Significance analysis of microarray (SAM; academic version 2.23B) was used to identify differentially expressed genes. Different number of significant genes could be obtained depending on the SAM median false discovery rate (FDR) and a minimum fold change. a number of genes up-regulated; b number of genes down-regulated
