CASP2 and neoplasm: Comparisons of the differentially expressed genes (DEGs) were performed between (i) WT and Casp2−/− tumors to identify genes associated with tumorigenesis following Casp2 loss and (ii) between the EμMyc/Casp2−/− and Th-MYCN/Casp2−/− tumor samples, to narrow down candidate genes affected by Casp2 deficiency and/or that enhance lymphomagenesis in EμMyc/Casp2−/− mice.
