To that end, the authors initially compared the gene expression profiles of doxorubicin-exposed versus untreated lymphomas, specifically senescence-competent primary Eμ-Myc transgenic Bcl2-overexpressing lymphomas (dubbed as Eμ-Myc;Bcl2) and senescence-incompetent Suv39h1-deficient Eμ-Myc;Bcl2 lymphomas. Here, MYC is linked to lymphoma.
