Oncogenic p53 in lung cancer does more than disrupt genome integrity. A new study shows that mutant, gain-of-function p53 actively drives a replication-based loop that both accelerates tumor growth and creates a targetable vulnerability.
Mutations in tumor suppressor p53 that gain oncogenic functions (Onc-p53) are frequent in lungs and many other solid tumors often associated with chromosome aberrations. Why cells or tumors with Onc-p53 develop chromosomal aberrations and whether the abnormalities contribute to tumor growth remain e...
