WebNov 21, 2006 · Examination of frequent genetic alterations in human cancer showed that PTEN (phosphatase with tensin homology on chromosome 10) is the major enzyme that decreases PI (3,4)P 2 and PI (3,4,5)P 3 cell content. Nonetheless, interpretation of the complexity of PTEN regulation remains a matter of debate. WebWe found that the phosphatase PTEN links Treg cell stability to repression of type 1 helper T cell (TH1 cell) and follicular helper T cell (TFH cell) responses. Depletion of PTEN in Treg cells resulted in excessive TFH cell and germinal center responses and spontaneous inflammatory disease. These defects were considerably blocked by deletion of ...

WebNov 15, 2010 · Using a retrovirus vector encoding PTEN phosphatase mutants that retain either protein- or lipid-phosphatase activity on a Src(Y527F)background, we report here that both lipid- and protein-phosphatase activities of PTEN contribute to the suppression of Src-induced podosome formation and associated invasive phenotypes in rat aortic smooth … WebDec 16, 2009 · This effect of PTEN re-expression in J82 was subsequently confirmed in an independent study . The G129E mutant form of PTEN has been used to demonstrate that the invasive phenotype of T24, which contains a mutation in PTEN, can be inhibited by the protein phosphatase activity of PTEN alone . This phenotype is likely to be of critical …
