Cell's recycling center implicated in division decisions

Researchers at The Johns Hopkins University have now identified a mechanism that overrides the cells’ warning signals, enabling cancers to continue to divide even without a robust blood supply. In the process, the researchers found that lysosomes — the cell’s protein “recycling centers” — help govern cell division decisions. They also uncovered new evidence that certain drugs can halt the growth of tumors that have high levels of the protein HIF-1alpha. Read more here.
