Cheresh and colleagues delineate a pathway that regulates tumour cell stemness and resistance to therapy. They find that the unliganded integrin αvβ3 is able to promote cancer cell self-renewal, tumour initiation and resistance to EGFR inhibitors by binding KRAS and RalB to activate the NF-κB pathway.
