DNA copy number validation by qPCR (A) and mRNA expression validation by RT-qPCR (B) of four candidate genes in clinical samples. The Y-axis is the mean DNA dosage ratio (A) or mean mRNA expression ratio (B) between candidate gene and the internal control gene in all samples analyzed. The P values of comparison between normal (N) and tumor (T) samples for each gene is as indicated.
