Reactivation of the tumor suppressor pten
WebJan 16, 2013 · Whereas much is known about gene activation by MYC, there is no established mechanism for the majority of MYC-repressed genes. We report that MYC transcriptionally activates the PTEN tumor suppressor in normal cells to inactivate the phosphoinositide 3-kinase (PI3K) pathway, thus suppressing AKT activation. WebJun 7, 2002 · The tumor suppressor PTEN regulates cell migration, growth, and survival by removing the 3′-phosphate of phosphoinositides. Exposure of purified PTEN or of cells to H 2 O 2 resulted in inactivation of PTEN in a time- and H 2 O 2 concentration-dependent manner. Analysis of various cysteine mutants, including mass spectrometry of tryptic …

WebJul 6, 2015 · Summary: Enzymes (PI3K and PTEN) controlling cellular levels of 3-phosphorylated phosphoinositides are known as important drivers or suppressors of tumorigenesis in various cancers. In this issue of Cancer Discovery, Kofuji and colleagues and Chew and colleagues identify the lipid phosphatase INPP4B as a context-specific … WebThe PTEN gene provides instructions for making an enzyme that is found in almost all tissues in the body. The enzyme acts as a tumor suppressor, which means that it helps regulate cell division by keeping cells from growing and dividing (proliferating) too rapidly or in an uncontrolled way. To function, the PTEN enzyme attaches (binds) to ...
