Figure 3. Expression of c-Myc target genes at different Tc concentrations. Average expression profiles of groups 1 - 10 were calculated from 447 induced genes. Genes in the different groups required a 2-fold or higher change in expression compared with control cells (100ng/ml Tc). The graphs of groups 1 - 10 show the normalized average expression profiles calculated from the genes that belong to each group (number of genes per group in brackets).
