Cancer cell’s “self eating” tactic may be its weakness

Cancer cells use a bizarre strategy to reproduce in a tumor’s low-energy environment; they mutilate their own mitochondria! Researchers at Cold Spring Harbor Laboratory (CSHL) also know how this occurs, offering a promising new target for pancreatic cancer therapies. Why would a cancer cell want to destroy its own functioning […]
