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.
