TP53 and thymus lymphoma: In comparison to transcriptome of thymic lymphomas from p53+/− mice, we found 1215 and 1235 mapped genes differentially expressed in thymic lymphomas from vehicle and rapamycin treated Fbxw7+/−p53+/− mice respectively (fold-change 1.3; p < 0.05, Figure 1A), with 259 overlapping genes that were differentially expressed independent of rapamycin treatment (Figure 1A and 1B).
