The cellular origins of drug resistance in cancer
Nature Medicine, 2016Two new studies show that mechanisms of acquired resistance to targeted therapy in lung cancer do not necessarily pre-exist in resistant subclones. Instead, some cancers may harbor the potential to acquire a variety of drug-resistance mechanisms after response to targeted therapy.
