Phosphatase and tensin homologue deleted on chromosome 10 ( PTEN ), also referred to as mutated in multiple advanced cancers ( MMAC1 ) and TGF-β regulated and epithelial cell enriched phosphatase ( TEP1 ), was first discovered in 1997.1–3 Since its discovery, an entire network of interconnections to various other cellular pathways has been uncovered ...

Methods, 2015
PTEN was discovered as a membrane-associated tumor suppressor protein nearly two decades ago, but the concept that it can be secreted and taken up by recipient cells is revolutionary. Since then, various laboratories have reported that PTEN is indeed secreted and available for uptake by other cells in at least two different guises.

Expression of PTEN and PTEN pseudogene in endometrial carcinoma.
International Journal of Molecular Medicine, 2000PTEN is a tumor suppressor gene and its mutation is frequently found in endometrial carcinoma. Recently, the pseudogene of PTEN has been reported to be actively transcribed in a number of cells and tissues and a potential for translation is suggested.

For years, clinical and basic researchers have been aware of the presence of PTEN in the nucleus in cell culture, animal models, and both healthy and diseased human tissues. Despite the early recognition of nuclear PTEN, the understanding of the mechanisms of its nuclear localization, function in the nucleus, and importance in biology and human disease

Regulation of the PTEN phosphatase
Gene, 2006Phosphatase and tensin homologue deleted on chromosome 10 (PTEN) is a phosphatidylinositol phosphate phosphatase and is frequently inactivated in human cancers. The balance between phosphoinositide 3-kinase (PI3K) and PTEN determines PI(3,4,5)P3 levels. PI3K is regulated by a variety of intracellular and extracellular signals, but little is known about

0 d hysiological PTEN substrate is the lipidic second messener phosphatidylinositol-3,4,5-trisphosphate (PIP3). Thus, TEN reverts the phosphoinositide-3-kinases (PI3K) phoshorilation of phosphatidylinositol-4,5-bisphosphate (PIP2) o PIP3. As PIP3 activates the serine–threonine kinase Akt, hich is involved in anti-apoptosis, proliferation and oncoenesis,

Expert Review of Neurotherapeutics, 2008
The tumor suppressor PTEN dephosphorylates phospholipids generated through the activity of PI3K. PTEN thus antagonizes PI3K activity and regulates a multitude of cellular processes such as angiogenesis, motility, invasiveness, survival and proliferation, all of which can initiate and sustain the malignant phenotype.

The PTEN phosphatase has an active site motif characteristic for the protein tyrosine phosphatase superfamily, yet its major substrate is the membrane lipid phosphatidylinositol (3,4,5) trisphosphate (PIP3). PTEN is thus the major antagonist of PI3 kinase signaling, which explains its supreme role in tumor suppression, development, and growth control ...

Genetic profile, PTEN mutation and therapeutic role of PTEN in glioblastomas
International Journal of Oncology, 2002New therapeutic strategies are needed to improve survival in glioblastoma (GBM) the most malignant astrocytic tumor. We evaluated: a) the genetic status of 22 GBMs by comparative genomic hybridization (CGH); b) the specific role of mutation and/or homozygous deletion of PTEN in the genesis of GBM; and c) the possible therapeutic role of PTEN against ...
