Space-filling model of the PTEN protein (blue) complexed with tartaric acid (brown) [5] Phosphatase and tensin homolog (PTEN) is a phosphatase in humans and is encoded by the PTEN gene. [6] Mutations of this gene are a step in the development of many cancers, specifically glioblastoma, lung cancer, breast cancer, and prostate cancer.
Pentaerythritol tetranitrate (PETN), also known as PENT, pentyl, PENTA (ПЕНТА, primarily in Russian), TEN (tetraeritrit nitrate), corpent, or penthrite (or, rarely and primarily in German, as nitropenta), is an explosive material.
PTEN also refers to a member of the class, phosphatase and tensin homolog. [ citation needed ] This enzyme participates in 10 metabolic pathways : inositol phosphate metabolism , phosphatidylinositol signaling system , p53 signaling pathway , focal adhesion , tight junction , endometrial cancer , glioma , prostate cancer , melanoma , and small ...
The Prime Time Entertainment Network (PTEN) was an American television network that was operated by the Prime Time Consortium, a joint venture between the Warner Bros. Domestic Television Distribution subsidiary of Time Warner and the BHC Communications subsidiary of Chris-Craft Industries. First launched on January 20, 1993, and operating ...
PTEN inhibitors, such as bisperoxovanadium, [35] can enhance the PI3K/AKT pathway to promote cell migration, [36] survival [37] and proliferation. [7] While there are some concerns over possible cell cycle dysregulation and tumorigenesis, temporary and moderate PTEN inhibition may confer neuroprotection against traumatic brain injury [ 38 ] and ...
PTEN may mean: Prime Time Entertainment Network; PTEN (gene), a human tumour suppressor gene on chromosome 10 (and its protein: phosphatase and tensin homolog)
Loss of PTEN function leads to over-activation of Akt and is common in cancer cells (PTEN is a tumour suppressor). SH2-containing Inositol Phosphatase (SHIP) also dephosphorylates PI(3,4,5)P 3, at the 5' position of the inositol ring. [22] The PI3K-Akt pathway regulates PTEN levels by affecting its transcription and activity.
PtdIns(3,4,5)P 3 is dephosphorylated by the phosphatase PTEN on the 3 position, generating PI(4,5)P 2, and by SHIPs (SH2-containing inositol phosphatase) on the 5' position of the inositol ring, producing PI(3,4)P 2. [5] The PH domain in a number of proteins binds to PtdIns(3,4,5)P 3. Such proteins include Akt/PKB, [6] PDPK1, [7] Btk1, and ARNO ...
