Web1 dec. 2024 · HIF-1a is thought to be the key driver of angiogenesis in PanNET [32]. HIF-1a can be activated by two mechanisms in PanNETs [7,32]. First, HIF-1a is regulated by the von Hippel-Lindau tumor suppressor (VHL); the genetic or epigenetic inactivation of VHL can lead to an accumulation of HIF-1a. Second, tumor hypoxia can also activate HIF-1a. Web11 oct. 2012 · The mammalian target of rapamycin (mTOR) is a highly conserved PI3K-like serine/threonine kinase with functional homologs found in all studied eukaryotic organisms. 11 mTOR integrates nutrient, energy, oxygen sensing, and mitogenic input signals. 12 We found that mTOR also responds to inflammatory signals and mediates a previously …
WebWe demonstrate that TME-specific stressors including transforming growth factor–β (TGF-β), hypoxia, and nutrient deprivation selectively induce two Foxp3-specific deubiquitinases, ubiquitin-specific peptidase 22 (Usp22) and Usp21, by regulating TGF-β, HIF, and mTOR signaling, respectively, to maintain Treg fitness.
