Background: The 5-year survival rate for patients with advanced pancreatic neuroendocrine tumors (pNETs) is less than 30%. Notch signaling is a transmembrane receptor pathway with four distinct isoforms, activation of which is linked to cellular differentiation, cell fate, and viability. Both Notch1 and Notch3 signaling have been shown to be dysregulated in pNETs. Notch3 activation has been shown to repress Notch1 activity in other cancers. We hypothesize that activation of No...

Background: Cancer cells utilize both oxidative phosphorylation (OXPHOS) and glycolysis to generate energy. Switching between OXPHOS and glycolysis can promote tumor progression. The mechanisms governing oncogenic metabolic flexibility are largely unknown, but recent data has suggested that Notch1 dysregulation in cancer cells can contribute to altered metabolic phenotypes. We hypothesized that Notch1 signaling supports metabolic flexibility in pancreatic neuroendocrine tumor ...
