Pills of PTEN? In and out for tumor suppression

Cell Res. 2013 Oct;23(10):1155-6. doi: 10.1038/cr.2013.103. Epub 2013 Aug 6.

Abstract

The tumor-suppressive activity of PTEN has always been attributed to its endogenous intracellular function. Recently two different groups have demonstrated that PTEN is secreted/exported into the extracellular environment for uptake by recipient cells, and functions as a tumor suppressor in a cell non-autonomous manner.
