Validation of array data by RT-PCR. Plots of relative gene expression (log2 values) measured with RT-PCR are shown. The x-axis shows the samples, the y-axis shows the log2 relative gene expression value. Samples with retention are compared with samples with loss (18q) or gain (1q, 8q and 20q) of a specific chromosome arm. The line indicates the mean. P-values were computed by Student's t-test.
