Quantitation of differentially expressed genes in ten paired tumor and non-neoplastic samples. Panel A. Relative expression of epithelial genes in tumor tissue compared to paired non-neoplastic tissue. Panel B. Relative expression of stromal genes in non-neoplastic tissue compared to paired tumor tissue. Data indicates fold changes in gene expression using the 2-ddCt method. Values greater than 1 indicate greater expression in tumor (A) or non-neoplastic (B) tissue. The upper and lower boundaries of the boxes define the quartiles, 75% and 25%, respectively, and the black bar represents the median value. The diamond indicates the mean.
