  1. Results are expressed as normalized N-fold differences in target gene expression relative to the ‘Total-TBP’ expression. These Ntarget values of the tumor samples were normalized such that the value for the ’basal mRNA level‘ (Ct = 35) was 1Target mRNA levels that were total absence or very low (Ct > 38) in tumor samples were scored ‘0’ for non expressed.
  2. Median and range in () are given for each gene in the different experimental conditions. 1Mann Whitney Test; NS, not significant; in bold, significant.
