Tissue Microenvironment Affects Activity of PTEN in Leukemia
The tumor suppressor PTEN, which is underexpressed in many cancers, dephosphorylates phosphatidylinositol (3,4,5)-triphosphate and thus inhibits activity of phosphatidylinositol 3-kinases involved in growth factor and survival factor signaling through effectors such as Akt and mTOR. As reported in...
