Cancer: Three birds with one stone

Franck Toledo1 & Boris Bardot1

The core domain of the p53 protein has been found to affect microRNA processing — its third known antitumour activity. Most cancerous p53 mutations affect this domain and may abolish all tumour-suppressor functions.

The p53 protein is a major tumour suppressor. The gene that encodes it (TP53) is mutated in about half of human cancers, and most remaining tumours find other ways to inactivate the p53 pathway1.
