Importantly, Eμ-Myc;Nfkb2-/- transgenic displayed a moderately accelerated course of lymphoma development and, accordingly, had a shorter lifespan, with a median survival of 171 days compared to 205 days median survival in their Eμ-Myc;Nfkb2+/+ littermates (Figure 4a, p = 0.0307). The gene discussed is NFKB2; the disease is lymphoma.
