PTEN is a lipid phosphatase that functions as a dose-dependent tumor suppressor through the PI3K/AKT pathway. Here the authors describe a signaling feedback mechanism where PTEN stability is regulated through transcriptional upregulation of X-linked ubiquitin-specific protease 11 (USP11) via the PI3K/FOXO pathway.
