Indeed, GSEA highlighted the proximity of 4-h-CTX-in vivo-challenged senescence-capable Eμ-myc lymphomas without Bcl2 protection and 5d-ADR-in vitro-senescent bcl2-engineered lymphomas based on similar ES of a large number of common gene sets in their expression profiles (Fig. 5c). Here, BCL2 is linked to lymphoma.
