Normal mammary epithelial cells require attachment to the extracellular matrix (ECM) for survival, but in breast cancers tumour cells acquire the ability to survive outside their natural ECM niches. Here it is found that cell detachment induces metabolic defects which can be rescued by both the expression of the oncogene ERBB2 and — unexpectedly — by antioxidants, which, in this context, help promote cancer cell survival and proliferation.
