Study revises theory of how PTEN, a critical tumor suppressor, shuts off growth signals

Today, scientists at Cold Spring Harbor Laboratory (CSHL) publish new evidence explaining precisely how the protein encoded by PTEN (called PTEN) works -- specifically, how it is recruited to particular locations in our cells where pro-growth signals need to be shut off. The new evidence, assembled by a team led by CSHL Associate Professor Lloyd Trotman, contradicts a long-held assumption about PTEN function, and could help scientists design more effective drugs to counteract cancer's hallmark trait, uncontrolled cellular growth...
