Gene Information

General description

The protein and lipid phosphatase PTEN (phosphatase and tensin homolog deleted on chromosome ten) has been suggested to play a role in tumorgenesis. PTEN is a tumor suppressor whose loss permits constitutive signaling through the PI3K pathway and is sufficient to cause cancer. In normal cells, in conjunction with FOXO1A and PTEN function together to restrain cell growth. PTEN metabolizes the product of PI3K phosphorylation of PI(4,5)P2 following receptor activation, creating PI(3,4,5)P3. In cells lacking PTEN, there are elevated levels of PI(3,4,5)P3, which acts as a potent second messenger promoting oncogenesis. Restoration of PTEN function is considered a novel approach to cancer therapy. Overexpression of PTEN inhibits cell migration, and expression of antisense PTEN mRNA enhances migration.

PTEN and p16 frequently undergo (epi)genetic aberrations in melanoma resulting in decreased, or absent, protein levels. We investigated the prognostic significance of these tumor suppressor genes in melanoma brain metastases (MBMs). Immunohistochemical analysis was performed on archived tissue sections from

PTEN is among the most commonly mutated tumor suppressor genes in human cancer. However, studying the role of PTEN in the pathogenesis of cancer has been limited, in part, by the paucity of human cell-based isogenic systems that faithfully model
