Quantitative real time RT-PCR analysis of microarray results. Real time RT-PCR of seven up-regulated and three down-regulated genes in response to camptothecin treatment. Relative expression values were normalised using actin as housekeeping gene. Induction values obtained in the microarray hybridization are indicated for each gene (*). The fold-change expression were calculated from three independent biological replicates; the biological replicates and standard errors are indicated (error bars). PDI (protein disulfide isomerase, U90944), HRGP (hydroxyproline-rich glycoprotein, BM073956), LRR (leucine rich repeats protein, CK370970), RNR1 (ribonucleotide reductase large subunit, BM079174), TBPIP1 (TBP-1 interacting protein, CA827618), RAD51B (AF079429) XRI-1 (X-ray induced gene 1, AY108750), CycB1 (cyclin IaZm, AI622454), B3 (B3 domain containing DNA binding protein, CO531505), E98 (HMG1/2 family transcription factor, AY104178).
