Overlapping gene lists in gene expression comparisons in tumor and pretumor B cells. Nineteen probes are significantly differentially expressed when comparing LMP2A/λ-MYC and λ-MYC tumor B cells. In contrast, 199 probes are differentially expressed when comparing LMP2A/λ-MYC and λ-MYC pretumor B cells. A total of 1196 probes and 1763 probes are differentially expressed when comparing pretumor B cells with tumor B cells in LMP2A/λ-MYC and λ-MYC, respectively. Each circle in the Venn diagram represents the probes that are differentially expressed in comparing the samples indicated in the corners. The probes that are differentially expressed in multiple comparisons are shown by the overlapping circles.
