Cancer researchers identify new function in an old acquaintance

Cells have two different programs to safeguard them from developing cancer. One of them is senescence. It puts cancer cells into a permanent sleep. Now researchers have discovered that an enzyme known to be active in breast cancer blocks this protection program and boosts tumor growth. They succeeded in blocking this enzyme in mice with breast cancer, thus reactivating senescence and stopping tumor growth. (Mehr in: Cancer News — ScienceDaily)
