Reactivation of the tumor suppressor pten
WebSep 15, 2024 · Loss of the tumor suppressor PTEN in human cancers has recently been shown to contribute to resistance to immunotherapy; unfortunately, therapeutic reactivation of PTEN has remained elusive. Chemerin (retinoic acid receptor responder 2, RARRES2 ) is a leukocyte chemoattractant known to recruit effector immune cells, and is often … WebPTEN is a critical tumor suppressive phosphatase that is active in its dimer configuration at the plasma membrane. Polyubiquitination by the ubiquitin E3 ligase WWP1 (WW domain–containing ubiquitin E3 ligase 1) suppressed the dimerization, membrane recruitment, and function of PTEN.
