摘要

Evidence linking metabolic alterations to cancer progression is accumulating. It seems that cancer cells must sustain their energy production and remain well fed to survive detachment from their normal habitat.rnGood cells perform their physiological activities only at the right time and in the right place. When removed from their natural surroundings they self-destruct - an event that is termed anoikis (Greek for homelessness). Not so cancer cells: they survive, invade other tissues and continue to grow in unfamiliar territories. On page 109 of this issue, Schafer et aV show that cancer-inducing oncogenes may protect cells from anoikis by maintaining the cells' glucose consumption. Their work demonstrates that the death of normal 'away-from-home' cells is caused by starvation, and strongly connects cellular metabolism to cancer.rnAnoikis occurs when cells detach from the basement membrane or the extracellular matrix, both of which provide them with survival signals.
