The number of genes that were differentially expressed per group is described in S1 Table. Gene expression analyses showed that 81 genes were commonly overexpressed throughout the three tested groups (see S2 Table) (a differential expression larger than |2| was consider statistically significant). Table 1 presents the genes from this list that were overexpressed at least a 10-fold. It was noted that there were no trends in the differential expression of most genes with respect to drug concentration.
