Mechanistically, we showed that mutant p53 collaborates with the Notch1 intracellular domain (NICD) to abrogate p63\/p73-mediated repression of HES1 and ECM1. As a result, HES1 and ECM1 are overexpressed, leading to lymphomagenesis. Thus, we identify a context where mutant p53 contributes to pathogenesis of T lymphoblastic lymphoma by collaborating with the Notch1 pathway to hijack the p63\/p73-regulated transcriptional program.\n
