PTEN

PTEN is a gene that produces a protein acting as a tumor suppressor, meaning it helps regulate cell growth and prevent uncontrolled cell division. It does this by turning off certain signals that encourage cells to grow and divide. When PTEN doesn't work properly due to mutations, it can lead to excessive cell growth, increasing the risk of developing cancers, especially in the brain, prostate, and other tissues. Overall, PTEN plays a vital role in maintaining healthy cell function and preventing tumor formation.
