The relative expression of genes analysed by qRT-PCR is reported for each sample. The mean expression of controls was used as calibrator (set equal to 1) and beta actin was used to normalise data. Fold changes obtained from microarray analysis are shown for each analysed gene. Page 9 of 12 (page number not for citation purposes)
