P53/R26-Zeb2tg/+ or P53/R26-Zeb2tg/tg mice developed tumours significantly faster, after 15.5 and 12.7 weeks, respectively, and with a complete shift towards haematopoietic neoplastic lesions (100%), mainly precursor T-cell lymphoma (85.7 and 87.5%; Fig. 2j and Supplementary Table 1). Here, TP53 is linked to T-cell non-Hodgkin lymphoma.
